Alasdair MacIntyre described the late modern West as driven by two moral values: efficiency and effectiveness. Regardless of whether you accept MacIntyre's overarching story, it seems clear that efficiency and effectiveness have achieved a zenith in institutional health care structures, such that these two aspects of care become the final arbiters of what counts as “good” care. At the very least, they are dominant in many clinical contexts and act as the interpretative lens for the judgments of successful health care (...) managers. The drive of efficiency can also be seen in “lean” management methods (originally imported from the automotive manufacturing industry) increasingly deployed in the intensive care unit. This drive gives us pause. The high stress of the ICU is exacerbated by the enormous complexity of technological interventions designed to maintain physiological functioning as the body heals, as well as the ever‐present concerns related to cost, effectiveness, and efficiency. The ICU, therefore, provides an illustrative view of the challenges facing clinicians, as well as resource managers, in terms of delivering care. In short, the goal of technocratic efficiency often ends up at odds with humane purposes. To better understand these contemporary health care dynamics, we conducted a limited series of focus group discussions and interviews with residents experienced in the challenges of delivering care in the ICU environment. In what follows, we highlight some narrative observations drawn from these focus groups. We found a recurrent and disconcerting refrain among our informants that has not been adequately described or addressed in the literature: technocratic management techniques have crept into and bifurcated clinical care strategies in the ICU. Specifically, we highlight the influence of concerns around efficiency and effectiveness and the ways in which these foci have contributed to a bifurcation in care in the ICU along two trajectories: either compassionate care or curative care.

Quarantine and spatial distancing measures associated with COVID-19 resulted in substantial changes to individuals’ everyday lives. Prominent among these lifestyle changes was the way in which people interacted with media—including music listening. In this repeated assessment study, we assessed Australian university students’ media use throughout early stages of the COVID-19 pandemic in Australia, and determined whether media use was related to changes in life satisfaction. Participants were asked to complete six online questionnaires, capturing pre- and during-pandemic experiences. The results indicated (...) that media use varied substantially throughout the study period, and at the within-person level, life satisfaction was positively associated with music listening and negatively associated with watching TV/videos/movies. The findings highlight the potential benefits of music listening during COVID-19 and other periods of social isolation. (shrink)

This qualitative study focused on how two women African American teachers understand the purpose of teaching social studies and citizenship. The multiple identities as African American women and teachers along with their knowledge of African American history impacted the way notions of citizenship were understood and taught to students. The teachers drew on tenets of Black Feminist thought to make sense of construct of citizenship. Instead of conveying traditional notions of citizenship that include personal responsibility, patriotism, and membership to the (...) nation state, they rejected these constructs of citizenship and understood their role as social studies teachers to instill notions of community membership and agency as aspects of citizenship. African American teacher's alternative notions of citizenship may provide a framework by which reconceptualized multiple views of American citizenship may be presented. (shrink)

A recent surge of research has begun to examine music participation and well-being; however, a particular challenge with this work concerns theorizing around the associated well-being benefits of musical participation. Thus, the current research used Self-Determination Theory to consider the potential associations between basic psychological needs (competence, relatedness, and autonomy), self-determined autonomous motivation, and the perceived benefits to well-being controlling for demographic variables and the musical activity parameters. A sample of 192 Australian residents (17-85, Mage = 36.95), who were currently (...) participating in a musical activity at the time, completed an online questionnaire. Results indicated that females were more likely to perceive benefits to their well-being; and that how important an individual considers music in their life was positively related to perceived well-being. Importantly, the analyses also revealed that the basic needs of competency and relatedness were related to overall perceived well-being as well as specifically social, cognitive, and esteem dimensions of well-being. Autonomous motivation demonstrated significant associations with both an overall well-being score as well as four of five specific well-being subscales measured. Collectively, the findings indicate that Self-Determination Theory offers a useful theoretical framework to understanding the relationship between musical participation and well-being. Further, the pattern of findings reiterates the positive associations between musical participation and one’s psychosocial well-being, with broad implications for people involved in the facilitation of musical activity.

This paper explores the continuing relevance of Karl Rahner’s work on development of doctrine to a church within a world marked by an emerging postmodern consciousness. It focuses primarily on three elements of development as Rahner understands it, theological discussion, the influence of the Spirit and the role of church authority. The discussion of a possible definition of Mary as co-redemptrix and the controversy over the ordination of women are cited as concrete examples of issues of development facing the church (...) today. Rahner’s increasing awareness of the context of irreducible plurality that marks the world-church of today and tomorrow led him to the increasing conviction in the later works that the Spirit is leading the church to a deepening understanding of the central mysteries of faith rather than to a further proliferation of defined dogmas. In the later works especially, he encouraged an attitude of open discussion that reflects the confidence that the Spirit is with the whole church as it struggles to express its faith in ever changing contexts. The paper concludes that Rahner’s understanding of the complex balance of elements involved in authentic doctrinal development continues to offer valuable insight to today’s discussions. (shrink)

In this article I argue that despite the claims of some, all whites in racialized societies “have race.” But because of the current context of race in our society, I argue that scholars of “whiteness” face several difficult theoretical and methodological challenges. First is the problem of how to avoid essentializing race when talking about whites as a social collective. That is, scholars must contend with the challenge of how to write about what is shared by those racialized as white (...) without implying that their experiences of racialization all will be the same. Second, within the current context of color-blind racial discourse, researchers must confront the reality that some whites claim not to experience their whiteness at all. Third, studies of whiteness must not be conducted in a vacuum: racial discourse or “culture” cannot be separated from material realities. Only by attending to and by recognizing these challenges will empirical research on whiteness be able to push the boundaries of our understandings about the role of whites as racial actors and thereby also contribute to our understanding of how race works more generally.

Previous research has indicated older adults value listening to music as a leisure activity. Yet, recent research into listening practices broadly has often focused on younger adults and the use of newer, digital listening technologies. Nonetheless, the radio, which is familiar to older people who grew up with it at the forefront of family life, is important to consider with regard to listening practices and the potential associated well-being benefits. This research investigated older adults’ everyday radio listening practices, in order (...) to begin to understand how the radio fits into their daily lives and how it might influence their sense of well-being. Twenty-five Australian residents participated in semi-structured, one-to-one interviews. The results of a qualitative thematic analysis revealed themes concerning listening preferences, listening routines, access, and motivations/outcomes. While personal preferences were diverse, individuals clearly communicated these as well as their established listening routines and habits. Listener motivations varied: some people focused on the enjoyment that listening to the radio creates while some noted benefits to their well-being, such as relaxation, modifying their mood, and feelings of comfort and community. Radio listening practices can be defined in terms of differing engagement styles, as characterized using continua ranging from passive to active, or focused, listening as well as generalized or specific listening. Based on participants’ experiences, a proposed engagement space model links how people engage with the radio to the possible outcomes mentioned. Importantly, benefits to well-being can result from varied engagement styles. The findings presented provide an in-depth understanding of how the radio fits into older adults’ everyday life, with implications for considering how the radio might be used as a widely accessed, low-cost tool for maintaining and enhancing quality of later life.

Following Kenya’s independence in 1963, scientists converged on an ecologically sensitive area in southern Kenya on the northern slope of Mt. Kilimanjaro called Amboseli. This region is the homeland of the Ilkisongo Maasai who grazed this ecosystem along with the wildlife of interest to the scientists. Biologists saw opportunities to study this complex community, an environment rich in biological diversity. The Amboseli landscape proved to be fertile ground for testing new methods and lines of inquiry in the biological sciences that (...) were generalizable and important for shaping natural resource management policies in Kenya. However, the local community was in the midst of its own transformation from a primarily transhumant lifestyle to a largely sedentary one, a complex political situation between local and national authorities, and the introduction of a newly educated generation. This article examines the intersection of African history and field science through the post-colonial Africanization of Kenyan politics, the broadening of scientific practices in Amboseli in previously Western-occupied spaces to include Kenyan participants, and an increasing awareness of the role of local African contexts in the results, methods, and implications of biological research. “Africanization” as an idea in the history of science is multifaceted encompassing not just Africans in the scientific process, but it needs an examination of the larger political and social context on both a local and national level.

Strategies to support the psychosocial well-being of older adults living in aged-care are needed; and evidence points toward music listening as an effective, non-pharmacological tool with many benefits to quality of life and well-being. Yet, the everyday listening practices of older adults living in residential aged-care remain under-researched. The current study explored older adults’ experiences of music listening in their daily lives while living in residential aged-care and considered how music listening might support their well-being. Specifically, what might go into (...) autonomous listening activities? 32 Australian residents living in two Australian care facilities participated in semi-structured interviews. The results of a qualitative thematic analysis revealed three themes pertaining to “previous music experiences and interest,” “current music listening,” and “barriers to listening.” While an interest in and access to music did not necessarily result in everyday listening practices, of those participants who did listen to music, perceived benefits included outcomes such as entertainment, enjoyment, relaxation, and mood regulation. Drawing on Ruud’s notion of music as a “cultural immunogen” supporting well-being and Self-Determination Theory, theoretical implications of the findings are addressed, relating to how to create and support music activities in aged-care facilities so that they are engaging, meaningful, and promote emotional regulation, community, and well-being.

Statistical properties in the visual environment can be used to improve performance on visual working memory tasks. The current study examined the ability to incidentally learn that a change is more likely to occur to a particular feature dimension and use this information to improve change detection performance for that dimension . Participants completed a change detection task in which one change type was more probable than others. Change probability effects were found for color and shape changes, but not location (...) changes, and intentional strategies did not improve the effect. Furthermore, the change probability effect developed and adapted to new probability information quickly. Finally, in some conditions, an improvement in change detection performance for a probable change led to an impairment in change detection for improbable changes. (shrink)

Throughout the animal kingdom, p53 genes function to restrain mobile elements and recent observations indicate that transposons become derepressed in human cancers. Together, these emerging lines of evidence suggest that cancers driven by p53 mutations could represent “transpospoathies,” i.e. disease states linked to eruptions of mobile elements. The transposopathy hypothesis predicts that p53 acts through conserved mechanisms to contain transposon movement, and in this way, prevents tumor formation. How transposon eruptions provoke neoplasias is not well understood but, from a broader (...) perspective, this hypothesis also provides an attractive framework to explore unrestrained mobile elements as inciters of late‐onset idiopathic disease.Also see the video abstract here.

The use of remember–know judgments to assess subjective experience associated with memory retrieval, or as measures of recollection and familiarity processes, has been controversial. In the current study we had participants think aloud during study and provide verbal reports at test for remember–know and confidence judgments. Results indicated that the vast majority of remember judgments for studied items were associated with recollection from study , but this correspondence was less likely for high-confidence judgments . Instead, high-confidence judgments were more likely (...) than remember judgments to be associated with incorrect recollection and a lack of recollection. Know judgments were typically associated with a lack of recollection , but still included recollection from the study context . Thus, although remember judgments provided fairly accurate assessments of retrieval including contextual details, know judgments did not provide accurate assessments of retrieval lacking contextual details.

It is estimated that 300,000 children 0–14 years of age are diagnosed with cancer worldwide each year. While the absolute risk of cancer in children is low, it is the leading cause of death due to disease in children in high‐income countries. In spite of this, the etiologies of pediatric cancer are largely unknown. Environmental exposures have long been thought to play an etiologic role. However, to date, there are few well‐established environmental risk factors for pediatric malignancies, likely due to (...) technical barriers in collecting biological samples prospectively in pediatric populations for direct measurements. In this review, we propose the use of novel or underutilized biospecimens (dried blood spots and teeth) and molecular approaches for exposure assessment (epigenetics, metabolomics, and somatic mutational profiles). Future epidemiologic studies of pediatric cancer should incorporate novel exposure assessment methodologies, data on molecular features of tumors, and a more complete assessment of gene‐environment interactions.

What happens when we blur time and allow ourselves to haunt or to become haunted by ghosts of the past? Drawing on archaeological, historical, and ethnographic data, Blurring Timescapes, Subverting Erasure demonstrates the value of conceiving of ghosts not just as metaphors, but as mechanisms for making the past more concrete and allowing the negative specters of enduring historical legacies, such as colonialism and capitalism, to be exorcised.

There are increasing concerns that research regulatory requirements exceed those required to manage risks, particularly for low- and negligible-risk research projects. In particular, inconsistent documentation requirements across research sites can delay the conduct of multi-site projects. For a one-year, negligible-risk project examining biobank operations conducted at three separate Australian institutions, we found that the researcher time required to meet regulatory requirements was eight times greater than that required for the approved research activity. In total, 76 business days were required to (...) obtain the necessary approvals, and site-specific processes required twice as long as primary Human Research Ethics Committee and Research Governance Office processes. We describe the impact of this administrative load on the conduct of a one-year, externally-... (shrink)

Objective: To examine changes in patients’ desired control of the deep brain stimulator and perception of global life control throughout DBS.Methods: A consecutive cohort of 52 patients with Parkinson’s disease was recruited to participate in a prospective longitudinal study over three assessment points. Semi-structured interviews assessing participants’ desire for stimulation control and perception of global control were conducted at all three points. Qualitative data were coded using content analysis. Visual analog scales were embedded in the interviews to quantify participants’ perceptions (...) of control over time.Results: Participants reported significant increases in their perception of global control over time and significant declines in their desired control of the stimulation. These changes were unrelated to improvements in motor symptoms. Improvements in global control were negatively correlated with a decline in desired stimulation control. Qualitative data indicate that participants have changed, nuanced levels of desired control over their stimulators. Increased global life control following DBS may be attributed to increased control over PD symptoms, increased ability to engage in valued activities, and increased overall self-regulation, while other domains related to global control remained unaffected by DBS.Conclusions: There are few empirical data documenting patients’ desire for stimulation control throughout neuromodulation and how stimulation control is related to other aspects of control despite the growing application of neuromodulation devices to treat a variety of disorders. Our data highlight distinctions in different types of control and have implications for the development of patient-controlled neurostimulation devices. (shrink)

The present study investigated relations between personality and values on the one hand and compensation preferences on the other. We hypothesized that HEXACO Honesty-Humility and self-transcendence versus self-enhancement values predict preference for higher relative compensation level and that HEXACO Openness to Experience and openness to change versus conservation values predict preference for compensation variability. Furthermore, we expected perceived utility of money and risk aversion to mediate the respective relations. The hypotheses were tested using a sample of 2,210 employees from a (...) large international organization. The results provided support for the direct and mediated relations between personality and values on the one hand and preferences for compensation variability and level on the other. (shrink)

Karl Rahner was one of the most significant theological voices of the twentieth century. For many his theology has come to symbolise the Catholic Church's entry into modernity. Part of his enduring appeal lies in his ability to reflect on a whole variety of issues in theology and spirituality and concentrate this plurality into a few basic convictions. This Cambridge Companion provides an accessible introduction to the main themes of Rahner's work. Written by an international array of experts, it will (...) be of interest to both students and scholars alike. Each chapter serves as a guide to its topic and recommends further reading for additional study. The contributors also assess Rahner's significance for contemporary theology by bringing his thought into dialogue with many current concerns including: religious pluralism, spirituality, postmodernism, ecumenism, ethics and developments in political and feminist theologies.

Mirrored-self misidentification is the delusional belief that one's own reflection in the mirror is a stranger. In two experiments, we tested the ability of hypnotic suggestion to model this condition. In Experiment 1, we compared two suggestions based on either the delusion's surface features (seeing a stranger in the mirror) or underlying processes (impaired face processing). Fifty-two high hypnotisable participants received one of these suggestions either with hypnosis or without in a wake control. In Experiment 2, we examined the extent (...) to which social cues and role-playing could account for participants' behaviour by comparing the responses of 14 hypnotised participants to the suggestion for impaired face processing (reals) with those of 14 nonhypnotised participants instructed to fake their responses (simulators). Overall, results from both experiments confirm that we can use hypnotic suggestion to produce a compelling analogue of mirrored-self misidentification that cannot simply be attributed to social cues or role-playing.

The empirical literature exploring lawyers and their moral decision making is limited despite the “crisis” of unethical and unprofessional behavior in the bar that has been well documented for over a decade. In particular we are unaware of any empirical studies that investigate the moral landscape of the health lawyer’s practice. In an effort to address this gap in the literature, an interdisciplinary team of researchers at Vanderbilt University designed an empirical study to gather preliminary evidence regarding the moral reasoning (...) of health care attorneys. The primary research question was how health lawyers respond when they encounter ethical or moral dilemmas in their practice for which the law fails to offer a bright-line solution. In exploring this question, we sought to understand better what motivations or influences guide action when health lawyers confront ethical quandaries, and whether there are specific differences, e.g., gender, experience, or religiosity, that are associated with specific responses to situations testing ethical or moral boundaries.

A função social da biblioteca pública está estreitamente vinculada a um determinado espaço geográfico para desenvolver ações que integrem demandas de informação, educação e cultura na comunidade. Essa noção fundamental outorga o rol de atributos operacionais das competências políticas legitimadas em processos históricos para essas instituições. Com o objetivo de analisar o contexto teórico qualificado ao sentido de comunidade é que o presente artigo estabeleceu uma reflexão sobre o papel social da biblioteca pública na contemporaneidade. Metodologicamente foi realizada uma pesquisa (...) bibliográfica que se orientou pela revisão de literatura guiada pelos questionamentos apresentados por Rabello (1987), Sperry (1993), Pinheiro (2009) e Milanesi (2013). Como resultado, verificou-se que atualmente as bibliotecas públicas estão perdendo espaços norepertório de interesses de sua comunidade. Failla (2021) constatou essa tendência em duas pesquisas realizadas sucessivamente no Brasil, nos anos de 2015 e 2020.

Writing in 1999, legal ethics scholar Brad Wendel noted that “[v]ery little empirical work has been done on the moral decision making of lawyers.” Indeed, since the mid-1990s, few empirical studies have attempted to explore how attorneys deliberate about ethical dilemmas they encounter in their practice. Moreover, while past research has explored some of the ethical issues confronting lawyers practicing in certain specific areas of practice, no published data exists probing the moral mind of health care lawyers. As signaled by (...) the creation of a regular column “devoted to ethical issues arising in the practice of health law” in the Journal of Law, Medicine & Ethics, the time to address the empirical gap in the professional ethics literature is now. Accordingly, this article presents data collected from 120 health care lawyers. Presenting this population with a number of hypothetical scenarios relating to how they would respond when confronting an ethical dilemma without an obvious solution or when facing a situation in which their personal values were in tension with their professional obligations, this article represents a first step toward better understanding how lawyers who practice in health care settings understand and resolve the moral discomfort they encounter in their professional lives.

Participants were asked to draw inferences about correlation from single x,y observations. In Experiment 1 statistically sophisticated participants were given the univariate characteristics of distributions of x and y and asked to infer whether a single x, y observation came from a correlated or an uncorrelated population. In Experiment 2, students with a variety of statistical backgrounds assigned posterior probabilities to five possible populations based on single x, y observations, again given knowledge of the univariate statistics. In Experiment 3, statistically (...) naïve participants were given a problem analogous to that given in Experiment 1, framed verbally. Experiment 4 replicated Experiment 3 but added an “impossible to determine” response option. Models that rely on computing sample correlations make no predictions about these investigations. From a Bayesian perspective, participants’ inferences in all four experiments tended to make probabilistically valid inferences as long as the single datum was directional. The results are discussed in light of the Brunswikian notion of vicarious functioning. (shrink)

Introduction The goal of this project was to develop and validate a new tool to evaluate learners' knowledge and skills related to research ethics. Methods A core set of 50 questions from existing computer-based online teaching modules were identified, refined and supplemented to create a set of 74 multiple-choice, true/false and short answer questions. The questions were pilot-tested and item discrimination was calculated for each question. Poorly performing items were eliminated or refined. Two comparable assessment tools were created. These assessment (...) tools were administered as a pre-test and post-test to a cohort of 58 Indian junior health research investigators before and after exposure to a new course on research ethics. Half of the investigators were exposed to the course online, the other half in person. Item discrimination was calculated for each question and Cronbach's α for each assessment tool. A final version of the assessment tool that incorporated the best questions from the pre-/post-test phase was used to assess retention of research ethics knowledge and skills 3 months after course delivery. Results The final version of the REKASA includes 41 items and had a Cronbach's α of 0.837. Conclusion The results illustrate, in one sample of learners, the successful, systematic development and use of a knowledge and skills assessment tool in research ethics capable of not only measuring basic knowledge in research ethics and oversight but also assessing learners' ability to apply ethics knowledge to the analytical task of reasoning through research ethics cases, without reliance on essay or discussion-based examination. These promising preliminary findings should be confirmed with additional groups of learners. (shrink)

The basis of science is the hypothetico-deductive method and the recording of experiments in sufficient detail to enable reproducibility. We report the development of Robot Scientist "Adam," which advances the automation of both. Adam has autonomously generated functional genomics hypotheses about the yeast Saccharomyces cerevisiae and experimentally tested these hypotheses by using laboratory automation. We have confirmed Adam's conclusions through manual experiments. To describe Adam's research, we have developed an ontology and logical language. The resulting formalization involves over 10,000 different (...) research units in a nested treelike structure, 10 levels deep, that relates the 6.6 million biomass measurements to their logical description. This formalization describes how a machine contributed to scientific knowledge. (shrink)

Psychedelics have been recognized as model interventions for studying altered states of consciousness. However, few empirical studies of the shamanic state of consciousness, which is anecdotally similar to the psychedelic state, exist. We investigated the neural correlates of shamanic trance using high-density electroencephalography (EEG) in 24 shamanic practitioners and 24 healthy controls during rest, shamanic drumming, and classical music listening, followed by an assessment of altered states of consciousness. EEG data were used to assess changes in absolute power, connectivity, signal (...) diversity, and criticality, which were correlated with assessment measures. We also compared assessment scores to those of individuals in a previous study under the influence of psychedelics. Shamanic practitioners were significantly different from controls in several domains of altered states of consciousness, with scores comparable to or exceeding that of healthy volunteers under the influence of psychedelics. Practitioners also displayed increased gamma power during drumming that positively correlated with elementary visual alterations. Furthermore, shamanic practitioners had decreased low alpha and increased low beta connectivity during drumming and classical music and decreased neural signal diversity in the gamma band during drumming that inversely correlated with insightfulness. Finally, criticality in practitioners was increased during drumming in the low and high beta and gamma bands, with increases in the low beta band correlating with complex imagery and elementary visual alterations. These findings suggest that psychedelic drug-induced and non-pharmacologic alterations in consciousness have overlapping phenomenal traits but are distinct states of consciousness, as reflected by the unique brain-related changes during shamanic trance compared to previous literature investigating the psychedelic state.

The weed philosophy as a proposal for the decolonization of knowledge in education and resistance to contemporary challenges Abstract: Brazilian education is structured based on the coloniality of knowledge (QUIJANO, 2005) that permeates the history of our territory, determining a monoculture of the mind (SHIVA, 2003) in the way we understand the world. However, an education that has monocultural curricula at its core silences own and local thinking in different ways, leads to a subordinate relationship with knowledge. In view of the enormous challenges that the contemporary world in crisis has imposed, it is necessary that we rethink school curricula in order to promote a more meaningful education for the world to come. With this article, we aim to point out ways to deal with differences in the school context, redefining what is in fact “harmful” for today's world. We will analyze the relationship between the monoculture of mind and soil and the coloniality of knowledge, pointing out the potential of non-hegemonic knowledge to resist coloniality and its consequences. We will bring as a proposal a weed philosophy that seeks to learn from what was discarded and considered "harmful" by hegemonic knowledge, and that presents knowledge and strategies that allow us to resist contemporary challenges in a humanized way.

A questão que procuramos desenvolver neste artigo pode ser enunciada do seguinte modo: será que o conhecimento pode ser transmitido de forma representacional, por meio de uma explicação, sem que aquele que aprende faça uma experiência por si só daquilo que aprende? Amparado-se no pensamento de Hume, Deleuze, Rancière e Gallo, pretende-se mostrar que somente a experiência com o objeto pode promover a aprendizagem efetiva, violentando o pensamento para que este busque por si só seu sentido e forme sua própria (...) apreensão, e não a mera repetição de conteúdos partilhados e tidos como importantes, como temos encontrado nas escolas.The question that we develop in this study can be proposed as follows: can knowledge be transmitted in a representational way through an explanation in such a way that the one who is learning does not have an experience itself of what he is learning? Grounded on Hume, Deleuze, Rancière and Gallo, we aim to show that only the experience with the object can promote effective learning, for violating the thought to search by itself for its meaning and for its own understanding, and not for the mere repetition of contents that have been shared and taken as important, as we have seen in schools.

Learning in educational settings most often emphasizes declarative and procedural knowledge. Studies of expertise, however, point to other, equally important components of learning, especially improvements produced by experience in the extraction of information: Perceptual learning. Here we describe research that combines principles of perceptual learning with computer technology to address persistent difficulties in mathematics learning. We report three experiments in which we developed and tested perceptual learning modules to address issues of structure extraction and fluency in relation to algebra and (...) fractions. PLMs focus students’ learning on recognizing and discriminating, or mapping key structures across different representations or transformations. Results showed significant and persisting learning gains for students using PLMs. PLM technology offers promise for addressing neglected components of learning: Pattern recognition, structural intuition, and fluency. Using PLMs as a complement to other modes of instruction may allow students to overcome chronic problems in learning. (shrink)
