As computer science education makes its way into schools, diverse initiatives worldwide promote computer science education in K-12, often focusing on teaching algorithms and programming with block-based programming languages such as Scratch or App Inventor. However, alternatives to assess the learning of computer science concepts on this educational stage are still scarce. This chapter presents an automated rubric for assessing algorithms and programming concepts of App Inventor projects at middle school level. The assessment is based on a rubric proposed in alignment with the K-12 Computer Science Framework with satisfactory reliability and validity. The rubric has been automated through a web-based system that allows assessing App Inventor projects through static code analysis. As a result, it can support computer science education in practice providing feedback to students and teachers.

Although teachers need to assess computational thinking (CT) for computer science education in K-12, it is not easy for them to evaluate students’ programs based on the perspective. The purpose of this study was to investigate students’ CT skills reflected in their Scratch programs. The context of the study was a middle school coding club where seven students voluntarily participated in a five-week coding activity. A total of eleven Scratch programs were analyzed in two aspects: problem decomposition and program development. Results revealed that students demonstrated proper decompositions of problems, which supported program development processes. However, in some cases, students failed to decompose necessary parts as their projects got sophisticated, which resulted in the failure or errors of programs. Regarding program development, algorythmic thinking had been identified as the area to be improved. Debugging and evaluation of programs were the necessary process students needed to practice. Implications for teaching CT skills were discussed.

The purpose of this study was to identify international trends in K–12 computer science curricula in countries that have introduced computer science education. Content analysis method was used to analyze the country-wide curricula of 10 countries which have introduced computer science education at the primary level. The K–12 Computer Science Framework was used as a theoretical frame to analyze the curricula. The results show that most countries begin their curricula with subconcepts of algorithms, program development, and under impact of computing, along with the practice of creating computational artifacts; then, countries expand upon computer science concepts and practices as learners progressed through the higher grades. Further, countries tend to introduce computer science concepts and practices in stages; once concepts and practices are introduced, they continue across multiple grades. Three approaches to implementing computer science education into the country-wide curriculum were found: introducing computer science (a) as an independent subject, (b) within multiple subjects, and/or (c) as a part of transversal competencies or an independent computer science curriculum with a cross-curricular approach. These study findings can contribute to a worldwide effort to introduce computer science education at the primary level.

Many initiatives have focused on attracting girls and young women (K-12 or college) to computer science education. However, professional women who never learned to program have been largely ignored, despite the fact that such individuals may have many opportunities to benefit from enhanced skills and attitudes about computer programming. To provide a convenient learning space for this population, we created and evaluated the impacts of a nine-week web development workshop that was carefully designed to be both comfortable and engaging for this population. In this article, we report how the professionals’ attitudes and skills grew over the course of the workshop and how they now expect to integrate these skills and attitudes into their everyday lives.

AbstractThe pervasiveness of Computer Science (CS) in today’s digital society and the extensive use of computational methods in other sciences call for its introduction in the school curriculum. Hence, Computer Science Education is becoming more and more relevant. In CS K-12 education, computational thinking (CT) is one of the abused buzzwords: different stakeholders (media, educators, politicians) give it different meanings, some more oriented to CS, others more linked to its interdisciplinary value. The expression was introduced by two leading researchers, Jeannette Wing (in 2006) and Seymour Papert (much early, in 1980), each of them stressing different aspects of a common theme. This paper will use a historical approach to review, discuss, and put in context these first two educational and epistemological approaches to CT. We will relate them to today’s context and evaluate what aspects are still relevant for CS K-12 education. Of the two, particular interest is devoted to “Papert’s CT,” which is the lesser-known and the lesser-studied. We will conclude that “Wing’s CT” and “Papert’s CT,” when correctly understood, are both relevant to today’s computer science education. From Wing, we should retain computer science’s centrality, CT being the (scientific and cultural) substratum of the technical competencies. Under this interpretation, CT is a lens and a set of categories for understanding the algorithmic fabric of today’s world. From Papert, we should retain the constructionist idea that only a social and affective involvement of students into the technical content will make programming an interdisciplinary tool for learning (also) other disciplines. We will also discuss the often quoted (and often unverified) claim that CT automatically “transfers” to other broad 21st century skills. Our analysis will be relevant for educators and scholars to recognize and avoid misconceptions and build on the two core roots of CT.
