Context: With the introduction of Computer Science (CS) into curricula worldwide, teachers' adoption of CS pedagogical content is essential to ensure the long-term success of reform initiatives. Continuing Professional Development (CPD) programs play a key role in this process. Unfortunately, adoption is seldom evaluated in CS-CPDs or CPDs in…

Developing student interest is critical to supporting student learning in computer science. Research indicates that student interest is a key predictor of persistence and achievement. While there is a growing body of work on developing computing identities for diverse students, little research focuses on early exposure to develop multilingual…

Background and Context: Educators and researchers are interested in building the computational thinking (CT) skills of K-12 students. However, the availability of language-agnostic assessments for lower elementary graders remains limited. Objective: We present preliminary insights into the reliability and validity of the Computational Thinking…

Elementary school teachers are increasingly being asked to teach computer science (CS)--a subject area with which they often have little familiarity. To address this gap, teacher professional development (PD) is a common approach for helping teachers become familiar with CS content. This paper describes a collaborative PD designed to accompany a…

METRICS was a 5-year grant program funded by the U.S. Department of Education designed to immerse elementary school students in computer science. METRICS components included 1) creation and implementation of rigorous computer science curriculum units and assessments to support STEM coursework connected across all subjects through problem-based…

While increasing emphasis has been placed on computer science (CS) and computational thinking (CT) little is known about these topics in elementary classrooms. Significant equity gaps exist within CS/CT at the elementary level, with a major contributor being the lack of highly qualified CS/CT elementary teachers. Professional development (PD) for…

Background: Early exposure to Computer Science (CS) and Computational Thinking (CT) for all is critical to broaden participation and promote equity in the field. But how does the introduction of CS and CT into primary school curricula impact learning, perception, and gaps between groups of students? Methodology: We investigate a CS-curricular…

The focus of this research project was to examine how problem- based learning (PBL) impacts students' interest and knowledge in computer science (CS) at the elementary level. By focusing on a problem that emphasizes social activism, we hypothesized that PBL CS could increase interest for students. We employed an iterative design-based research…
