  1. Teaching-focused professional development (PD) programs offered at institutions of higher education (IHEs) are uniquely positioned to be levers of change that improve the quality of undergraduate science, technology, engineering, and mathematics (STEM) education in ways that broaden participation in STEM education, workforce development, and career pathways in the United States (US). PD programs and their potential to transform undergraduate STEM education, however, are understudied. This multiple-case study compares suites of PD programs offered at three IHEs in the US: a community college, an emerging research institution, and a research-intensive university. Each suite of PD programs is characterized in terms of program structure, implementation, and potential to transform undergraduate STEM education. The presented results illustrate the existence of a wide range of ways in which PD programs are structured and implemented. A key finding is a suite of PD programs offered at these IHEs has greater potential to transform undergraduate STEM education when embedded in an institutional culture that highly prioritizes the teaching enterprise. Lastly, the results are synthesized into an innovative framework. The framework can be used as a tool to design, implement, and evaluate PD programs so they have greater potential to transform undergraduate STEM education in the US.

  2. Within the field of K-2 CS education, unplugged computational thinking (CT) activities have been suggested as beneficial for younger students and shown to impact young students’ skills and motivation to learn about CS. This study sought to examine how children demonstrate CT competencies in unplugged sequencing tasks and how children use manipulatives to solve unplugged sequencing tasks. This case study approach examined two unplugged sequencing tasks for six children ranging from ages four to seven (pre-kindergarten to 2nd grade). Children showed evidence of several CT competencies during the sequencing tasks: (1) pattern recognition, (2) algorithms and procedures, (3) problem decomposition, and (4) debugging. The strategies and use of manipulatives to showcase CT competencies seemed to evolve in complexity based on age and developmental levels. Taking into account children’s abilities to demonstrate CT competencies, this study suggests that sequencing is a developmentally appropriate entry point for young children to begin engaging in other CT competencies. In addition, these unplugged sequencing tasks can also be easily integrated into other activities commonly experienced in early childhood classrooms.

  3. Students can begin to lose interest in CS as early as 2nd grade, indicating the importance of engaging students in CS as early as possible. This study examined the integration of computational thinking (CT) into literacy activities in early childhood education (K-2). We describe the co-design process of developing computational thinking literacy integrated curriculum for K-2, and preliminary results of K-2 student engagement in CT and literacy activities
