This article describes how phenomenography, as a qualitative research method, can be used to tackle key challenges in science education. It begins with an overview of the development of phenomenography. It then describes the philosophical underpinnings of phenomenographic inquiry, including ontological and epistemological roots, and its unique second-order perspective. From theoretical background to practicality, the paper uses rich examples to describe in detail the procedures of conducting a phenomenographic study, including sampling and data collection, analyzing phenomenographic data, and communicating key (...) findings. The paper concludes by showing how the phenomenographic method can be used to develop students’ conceptual understanding of scientific concepts, to inform effective instructional design in science teaching, and to identify and improve evidence-based factors in student learning to enhance learning outcomes in science.

With an increasing number of international schools, traditional EFL teaching methods may not satisfy students’ needs. This study aims to investigate perceptions of social media technologies and willingness to adopt such technologies to collaborate and communicate in multicultural classrooms among novice EFL schoolteachers in the Czech Republic. The participants were 100 novice EFL schoolteachers in Prague and the South Moravian regions of the Czech Republic. The study used a mixed research method consisting of a survey and a semi-structured interview. The (...) survey examined the participants’ appraisal and concerns of using social media technologies to collaborate and to communicate as well as the level of willingness to use social media technologies. A hierarchical cluster analysis using participants’ responses regarding their attitudes and behavioural tendency towards using Web 2.0 social media technologies in language classrooms identified three clusters of teachers. The teachers who were most likely to adopt social Web 2.0 technologies were those who had the highest ratings on both appraisals and concerns regarding the use of social media in language classrooms. The results from the semi-structured interviews were consistent with those from the survey. Together, the results from the two stages demonstrated that most pre-service teachers favoured using Web 2.0 technology for collaboration and communication among colleagues and stakeholders in a broader community, but they displayed contrasting levels of appraisal of and concerns towards using social media technologies. Participants believed that this might be due to their different levels of ICT proficiency, workload, and working environment. The political and practical implications in K-12 education in the Czech context are also discussed. (shrink)

Feedback plays a crucial role in the writing processes. However, in the literature on foreign language writing, there is a dearth of studies that compare the effects of teacher feedback and automated feedback on both cognitive and psychological aspects of FL writing. To fill this gap, the current study compared the effects of teacher feedback and automated feedback on both revision quality and writing proficiency development, and perceived usefulness and perceived ease of use of the feedback in English writing among (...) English learners as an FL in China. It also investigated students’ perceptions of the strengths and weaknesses of the two types of feedback. The study adopted a mixed-methods design. The quantitative method collected the data through a pre-test and a post-test, which measured the participants’ English writing proficiency development; a writing task, which received either teacher feedback or automated feedback; and a close-ended questionnaire, which examined students’ perceived usefulness and perceived ease of use of the feedback. The qualitative method collected the data through an open-ended questionnaire, which examined the participants’ perceptions of the strengths and weaknesses of teacher feedback or automated feedback depending on the type of feedback they received. Chinese university EFLs in two English classes taught by the same English teacher participated in the study: one class received teacher feedback while the other received automated feedback using Pigaiwang. While the students in the two classes did not differ significantly on the pre-test of students’ writing proficiency, students who received teacher feedback scored significantly higher on revision than those who received automated feedback. Students in the teacher feedback class also had significantly higher ratings on perceived usefulness and perceived ease of use of the feedback than those in the automated feedback class. However, students in the automated feedback class obtained significantly higher scores on the post-test of the writing proficiency. The qualitative results identified three themes of strengths and two themes of weaknesses for the teacher feedback and the automated feedback, respectively. The results suggest that while teacher feedback has a more positive effect on the psychological aspect of FL writing, automated feedback may be more effective in developing FL writing proficiency in the long run.
