Title: Learning Computational Thinking Efficiently with Block-based Parsons Puzzles
To investigate learning system elements and progressions that affect computational thinking (CT) learning in block-based environments, we developed a Parsons Programming Puzzle (PPP) module within Scratch with scaffolding customized via a novel Blockly grammar. By varying the presentation and types of feedback encountered between- and within-subjects in a study of 579 adults, we identified features and scaffolding strategies that yield manageable cognitive load (CL), improved CT learning efficiency, and increased motivation, for a general populace. Findings indicate: 1) PPPs with feedback induce lowest CL; 2) an isolated palette, correctness feedback, and fading correctness feedback increase learning efficiency; 3) fading scaffolding can increase CT motivation. We analyze 12 conditions to provide insight to those developing block-based PPP systems with the aim to advance equitable CT education for all.  more » « less

    Using a design thinking approach, we surveyed and interviewed grade 6-9 teachers on their experience with Scratch and Parsons Programming Puzzles (PPP). The results lead us to extend Scratch with gameful PPP functionality focused on individual computational thinking (CT) concepts. In this paper, we vary elements of PPPs presented to 624 adult learners to identify those yielding manageable cognitive load (CL), and maximum CT motivation and learning efficiency, for a general populace. Findings indicate PPPs with feedback and without distractors limit CL, those with feedback produce highest CT motivation, and those with an isolated block palette and without distractors produce highest CT learning efficiency. We analyze study data across nine conditions to offer insight to those developing PPP systems with the aim to advance equitable CT education for all.

    We surveyed grade 6-9 teachers to learn teacher perceptions of student engagement with computational thinking (CT) and how well their needs are met by existing CT learning systems. The results and a literature review lead us to extend the trend of balancing Scratch’s agency with structure to better serve learners and reduce burden on teachers aiming to learn and teach CT. In this paper, we integrate Parsons Programming Puzzles (PPPs) with Scratch and analyze the effects on adults, who crucially influence the education of their children. The results from our small pilot study suggest PPPs catalyze CT motivation, reduce extraneous cognitive load, and increase learning efficiency without jeopardizing performance on transfer tasks.

    A literature review revealed that students learning computational thinking via Scratch often require substantial teacher support. We surveyed grade 6-9 teachers to learn their perceptions of student engagement with computational thinking (CT) and how well their needs are met by existing CT learning systems. The results led us to extend the trend of balancing Scratch’s agency with structure to better serve learners and reduce burden on teachers aiming to learn and teach CT. In this paper, we review architecture and implementation strategies developed to integrate Parsons Programming Puzzles (PPPs) with Scratch, and then analyze their effects on adults, who crucially influence the education of their children. The results from our pilot study suggest PPPs catalyze CT motivation, reduce extraneous cognitive load, and increase learning efficiency without jeopardizing performance on transfer tasks.

    Background Computational thinking (CT) is a crucial domain for children to develop in their early years. To increase children's access to CT learning resources, educational programs like PBS KIDS “Lyla in the Loop” have been developed to incorporate CT concepts through narrative structures where characters solve problems using the CT cycle. However, children need explicit guidance to effectively process both educational and narrative content. Engaging children in dialogues that connect educational content with the narrative has proven to enhance comprehension. Aims This study explores the effectiveness of using AI to enable this type of dialogues between children and a media character, supporting children in learning CT by connecting these concepts with everyday situations in “Lyla in the Loop.” Method Through a between-subject randomized control study with 160 children aged four to eight, we will compare children's learning and applications of CT concepts as well as narrative comprehension from AI-assisted dialogues to those who watched the broadcast version of the show without such dialogues. The study also examines the role of children's cognitive abilities and prior CT knowledge in their learning from the show, with or without AI-assisted dialogues. Expected results The findings could enhance our understanding of AI-based scaffolding strategies in children's media and offer practical implications for improving children's learning experiences.

    Solving mathematical problems is cognitively complex, involving strategy formulation, solution development, and the application of learned concepts. However, gaps in students' knowledge or weakly grasped concepts can lead to errors. Teachers play a crucial role in predicting and addressing these difficulties, which directly influence learning outcomes. However, preemptively identifying misconceptions leading to errors can be challenging. This study leverages historical data to assist teachers in recognizing common errors and addressing gaps in knowledge through feedback. We present a longitudinal analysis of incorrect answers from the 2015-2020 academic years on two curricula, Illustrative Math and EngageNY, for grades 6, 7, and 8. We find consistent errors across 5 years despite varying student and teacher populations. Based on these Common Wrong Answers (CWAs), we designed a crowdsourcing platform for teachers to provide Common Wrong Answer Feedback (CWAF). This paper reports on an in vivo randomized study testing the effectiveness of CWAFs in two scenarios: next-problem-correctness within-skill and next-problem-correctness within-assignment, regardless of the skill. We find that receiving CWAF leads to a significant increase in correctness for consecutive problems within-skill. However, the effect was not significant for all consecutive problems within-assignment, irrespective of the associated skill. This paper investigates the potential of scalable approaches in identifying Common Wrong Answers (CWAs) and how the use of crowdsourced CWAFs can enhance student learning through remediation.
