There is growing interest in teaching computational thinking to preschool children given evidence that they are able to understand and use CT concepts. One of the concepts that is central in CT definitions, is the concept of control structures, but it is not clear which tools and activities are successful in teaching it to young learners. This work aims at providing a comprehensive overview of tools that enable preschool children to build programs that include control structures, and analyzing empirical evidence (...) of the usage of these tools to teach control structures to children between 3 and 6. It consists of three parts: systematic literature review to identify tools to teach CT to young children, analysis of tools characteristics and the possibilities that they offer to express control structures, and SLR to identify empirical evidence of successful teaching of control structures to young children using relevant tools. This work provides an understanding of the current state of the art and identifies areas that require future exploration. (shrink)

IntroductionPreoperative neurocognitive disorder is a common condition affecting 14–51. 7% of the elderly population. General anesthesia has already been associated with the one-year post-operative neurocognitive disorder, specifically, a deficit in executive function, measured by the Trail Making Test B, but its long-term effects on cognitive function have not been investigated. We aimed to detect preO-NCD prevalence in patients scheduled for cardiac surgery and further investigate the possible role of previous general anesthesia in general preoperative cognitive status [measured via the Montreal (...) Cognitive Assessment ] and/or in executive functioning.MethodsIn this observational, prospective study, 151 adult patients scheduled for elective cardiac surgery underwent MoCA and TMT-B. Data on age, education, pGA, comorbidities, and laboratory results were collected.ResultsWe discovered a general cognitive function impairment of 79.5% and an executive function impairment of 22%. Aging is associated with an increased likelihood and education with a decreased likelihood of general cognitive impairment, but only education was significantly associated with a decreased likelihood of executive function impairment. While pGA did not significantly affect preO-NCD, a noteworthy interaction between aging and pGA was found, resulting in a synergistic effect, increasing the likelihood of executive function impairment.ConclusionWe found a high prevalence of preO-NCD in patients scheduled for cardiac surgery. General cognitive function impairment is highly associated with advancing age. However, older patients with at least one pGA appeared to be at an increased risk of preO-NCD, especially executive function impairment, suggesting that TMT-B should be associated with MoCA in the preoperative cognitive evaluation in this population.
