Demystifying computational thinking

This paper examines the growing field of computational thinking (CT) in education. A review of the relevant literature shows a diversity in definitions, interventions, assessments, and models. After synthesizing various approaches used to develop the construct in K-16 settings, we have created the following working definition of CT: The conceptual foundation required to solve problems effectively and efficiently (i.e., algorithmically, with or without the assistance of computers) with solutions that are reusable in different contexts. This definition highlights that CT is primarily a way of thinking and acting, which can be exhibited through the use particular skills, which then can become the basis for performance-based assessments of CT skills. Based on the literature, we categorized CT into six main facets: decomposition, abstraction, algorithm design, debugging, iteration, and generalization. This paper shows examples of CT definitions, interventions, assessments, and models across a variety of disciplines, with a call for more extensive research in this area.     

基于Scratch的儿童编程教育教学模式的设计与构建——以小学科学为例

儿童编程教育与基础课程的融合已成为编程教育领域研究的重要课题。儿童编程教育融入学科教学是转变与重塑计算教育观念的一次新尝试,也是推广与普及儿童编程教育的创新举措,更能助力编程教学与学科知识彼此协同发展。Scratch具有算法简化、媒体丰富的图像空间,自上而下、分而治之的修补理念,设计建造、交流协作的自由情境等特征优势,成为“用编程学”的媒介首选。基于此,文章以基于设计的研究为设计原则,并以4P学习法为理论基础,构建了以小学科学内容为案例的儿童编程与学科融合的教学模式,以期丰富与优化小学科学教学方式并探索推广多样化的儿童编程教学形式。

Collegiate athletes and career identity

Given the unique experiences of collegiate athletes and the need to facilitate their transition as they complete postsecondary education and join the workforce, the present study sought to evaluate a group-administered career development program at a US university focused on preparing students for the transition into professional life upon graduation. Utilizing the quantitative portion of the Life After Sport Scale, we surveyed National Collegiate Athletic Association Division I student athletes to examine the relationship between attending the career intervention sessions and career-athlete identity. Results suggested that attending one or more program session workshops was not significantly related to career-athlete identity, while student gender had the strongest association with this potentially important construct in student athlete career development. Research and practice implications of these findings are discussed.
