Title: Multilingual CS Education Pathways: Implications for Vertically-Scaled Assessment
The expansion of computer science (CS) into K-12 contexts has resulted in a diverse ecosystem of curricula designed for various grade levels, teaching a variety of concepts, and using a wide array of different programming languages and environments. Many students will learn more than one programming language over the course of their studies. There is a growing need for computer science assessment that can measure student learning over time, but the multilingual learning pathways create two challenges for assessment in computer science. First, there are not validated assessments for all of the programming languages used in CS classrooms. Second, it is difficult to measure growth in student understanding over time when students move between programming languages as they progress in their CS education. In this position paper, we argue that the field of computing education research needs to develop methods and tools to better measure students' learning over time and across the different programming languages they learn along the way. In presenting this position, we share data that shows students approach assessment problems differently depending on the programming language, even when the problems are conceptually isomorphic, and discuss some approaches for developing multilingual assessments of student learning over time.  more » « less

    Pair programming is a popular strategy in computer science education to teach programming to novices. In this study, we examined the effect of three different pair programming conditions on up- per elementary school students’ CS conceptual understanding. The three conditions were one-computer with roles (1C with roles), two computers without roles (2C no roles), and two computers with roles (2C with roles). These students were engaged in four days of computer programming activities and took the CS concept assessment, CS attitudes, and collaboration perceptions before and after the activities. We used the validated E-CSCA (Elementary Computer Science Concepts Assessment) to measure elementary students’ understanding of CS concepts. We tested the relation- ship of different pair programming conditions on the students’ CS conceptual understanding and found that different conditions impacted students’ CS conceptual understanding, wherein students in 2C roles demonstrated better CS learning than the other two conditions. The results also showed no changes in students’ CS attitudes and perceptions of collaboration before and after the activities. Furthermore, the results indicated no significant impact of these attitudinal factors on students’ learning CS concepts in pair programming settings. Our study highlights the importance of the roles and number of computers in pair programming settings, especially for elementary students.

    The rapid expansion of K-12 CS education has made it critical to support CS teachers, many of whom are new to teaching CS, with the necessary resources and training to strengthen their understanding of CS concepts and how to effectively teach CS. CS teachers are often tasked with teaching different curricula using different programming languages in different grades or during different school years, and tend to receive different professional development (PD) for each curriculum they are required to teach. This often leads to a lack of deep understanding of the underlying CS concepts and how different curricula address the same concepts in different ways. Empowering teachers to develop a deep understanding of CS standards, and use formative assessments to recognize common student challenges associated with the standards, will enable teachers to provide more effective CS instruction, irrespective of the curriculum and/or programming language they are tasked with using. This position paper advocates supporting CS teacher professional learning by supplementing existing curriculum-specific teacher PD with standards-aligned PD that focuses on teachers' conceptual understanding of CS standards and ability to adapt instruction based on student understanding of concepts underlying the CS standards. We share concrete examples of how to design standards-aligned educative resources and instructionally supportive tools that promote teachers' understanding of CS standards and common student challenges and develop teachers' formative assessment literacy, all essential components of CS pedagogical content knowledge.

    Subgoal labels are function-based instructional explanations that describe the problem-solving steps to the learner, highlighting the solution process. There is strong evidence that the use of subgoal labels within worked examples improves student learning in other STEM fields. Initial research shows that using subgoal labels within computer science improves student learning, but this has only been tested using a single programming concept (indefinite loops) with text-based programming languages. The proposers are currently expanding subgoal labels to the main programming concepts taught in an introductory programming course using an imperative programming language. In this BOF we seek to uncover tacit knowledge that programming instructors have in order to develop instructional materials that bridge the gap between students, who are CS novices, and instructors, who are CS experts, to improve learning for students who are under-prepared for or struggle in CS1. We will be seeking feedback on the selection of programming topics to be covered, the defined subgoals for those topics and the worked examples created for instructional purposes.

    Abstract: 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 students’ interest in computing. These students represent one of the fastest growing populations in the US, yet they are dramatically underrepresented in computer science education. This study examines identity development of upper elementary multilingual students as they engage in a year-long computational thinking curriculum, and follows their engagement across multiple settings (i.e., school, club, home, community). Findings from pre- and -post surveys of identity showed significant differences favoring students’ experiences with computer science, their perceptions of computer science, their perceptions of themselves as computer scientists, and their family support for computer science. Findings from follow-up interviews and prior research suggest that tailored instruction provides opportunities for connections to out-of-school learning environments with friends and family that may shift students’ perceptions of their abilities to pursue computer science and persist when encountering challenges.

    Until recently, computer science (CS) has been predominantly taught at upper-secondary or tertiary levels. Lately, however, CS curricula have been introduced into school systems from the very first year of school. In this paper, we undertake a participatory research approach, using focus group discussions between a group of experts in the field of evaluation and assessment at the primary level (K-5). The group considered the evaluation and assessment measures they have used, what their current needs are and how the CS education community can move towards meeting those needs. We present the discussion results as a position paper, situated in the context of broader education research. The experts identified three key priorities for the education research community: creating a universal taxonomy of assessment in the primary grades (K-5), creating measurements of student progression and growth over time, and creating culturally relevant evaluations and assessments. Through identifying key priorities, this work provides direction for urgently needed resource development and research directions for K-5 evaluation and assessment.
