Teachers play a critical role in student success with digital game-based learning in the classroom. That is a key finding from a study the Friday Institute for Educational Innovation’s STEM Cyberlearning team recently conducted to investigate how teachers utilized a digital genetics game to meet students’ learning needs.

The Undergraduate Computer Science Concept Assessment (UG-CSCA) is intended to assess STEM undergraduate students’ understanding of basic computer science and programming concepts – variables, conditionals, loops, and algorithms. The validation process of this assessment was guided and informed by a Focal Knowledge, Skills, and Abilities (FKSAs) Framework proposed by Grover and Basu (2017) and the K-12 CS Framework (K–12 Computer Science Framework, 2016). Block-based programming is used as the context for each item in the UG-CSCA. Several studies suggest that block-based programming is effective and appropriate computer programming for novices (Grover, Pea, & Cooper, 2015; Weintrop & Wilensky, 2015), and thus aligns with the intention of this assessment. The current version of the UG-CSCA was written for undergraduate students who are novices in computer science and programming. We believe that this assessment will be useful to instructors who teach introductory computer science and programming courses, as well as computer science education researchers. The instrument was designed for use in pre-intervention-post or longitudinal contexts, as well as for a diagnostic tool. We suggest providing 30-35 minutes for students to complete the assessment which consists of 26 multiple-choice questions.

The CS Concepts Inventory is intended to measure students’ understanding of the four core concepts of CS—variables, conditionals, loops and algorithms— taught at the middle school level. Additionally, we incorporated the concepts of debugging, comprehension and development into the assessment. The assessment was guided by a conceptual framework informed by a Focal Knowledge, Skills and Abilities—FKSAs framework developed by Grover and Basu (2017), the K-12 CS Framework (K–12 Computer Science Framework, 2016) and the Computer Science Teachers Association (CSTA) Standards (CSTA, 2017). The assessment utilizes elements from a block-based programming environment as the context for every question, based on findings that suggest learners, especially novice ones, experience less conceptual and cognitive difficulties using these tools (e.g., Grover, Pea & Cooper, 2015; Robins, Rountree, & Rountree, 2003).
