This study aims to determine the perceptions of undergraduates, who are receiving coding in a faculty of education, on modal representations employed in the teaching process and identify their transition skills between representations. The research used the quantitative research method, non-experimental design, and descriptive search models,…

The purpose of this study is to introduce a developed activity which is named "CityMap" and to present an example of the implementation and evaluation process of a computer science unplugged activity through this activity. The aim of this activity is to write algorithms of going from one place to another using step by step instructions.…

With the advancement in technology and the emphasis on computer science education, there has been a strong push for more widespread programming instruction at K-12 and higher education levels. Existing research has mostly focused on students at the secondary and post-secondary levels. Not much research has involved students at the elementary…

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…

This study employs a potential outcomes modeling approach to estimate the effect of Code.org's Professional Learning Program on Advanced Placement (AP) Computer Science Principles test taking and qualifying score earned for a recent cohort of 167 schools compared to a matched group of comparison schools. Results indicate substantial and…

Evaluating the quality of students' programs is necessary for better teaching and learning. Although many innovative learning environments for computer science have been introduced, the scarcity of program evaluation frames and tools is a demanding issue in the teaching practice. This study examined the quality of students' Scratch programs by…

Increasing the inclusion of underrepresented individuals in coding is an intractable problem, with a variety of initiatives trying to improve the situation. Many of these initiatives involve STEAM education, which combines the arts with traditional STEM disciplines. Evidence is emerging that this approach is making headway on this complex problem.…

Computational Thinking (CT) is pervasive in our daily lives and is useful for problem-solving. Decision-making is a crucial part of problem-solving. In the extant literature, problem-solving strategies in educational settings are often conveniently attributed to intuition; however, it is well documented that computer programmers might even have…

The purpose of this study is to identify secondary computer science (CS) teachers' pedagogical needs in the United States. Participants were selected from secondary teachers who were teaching CS courses or content in a school setting (public, private, or charter) or an after-school program during the time of data collection. This is a qualitative…

This paper is part of a wider action research project taking place at a secondary school in South Wales, UK. The overarching aim of the project is to examine the potential for aspects of literacy and computational thinking to be developed using extensible 'build your own block' programming activities. This paper examines classroom talk at an…
