• Title: Integrating Personalized Parsons Problems with Multi-Level Textual Explanations to Scaffold Code Writing
• Authors: Xinying Hou, Barbara J. Ericson, Xu Wang
• Abstract summary: Novice programmers need to write basic code as part of the learning process, but they often face difficulties. To assist struggling students, we recently implemented personalized Parsons problems, where students arrange blocks of code to solve them as pop-up scaffolding. Students found them to be more engaging and preferred them for learning, instead of simply receiving the correct answer.

• Abstract: Novice programmers need to write basic code as part of the learning process, but they often face difficulties. To assist struggling students, we recently implemented personalized Parsons problems, which are code puzzles where students arrange blocks of code to solve them, as pop-up scaffolding. Students found them to be more engaging and preferred them for learning, instead of simply receiving the correct answer, such as the response they might get from generative AI tools like ChatGPT. However, a drawback of using Parsons problems as scaffolding is that students may be able to put the code blocks in the correct order without fully understanding the rationale of the correct solution. As a result, the learning benefits of scaffolding are compromised. Can we improve the understanding of personalized Parsons scaffolding by providing textual code explanations? In this poster, we propose a design that incorporates multiple levels of textual explanations for the Parsons problems. This design will be used for future technical evaluations and classroom experiments. These experiments will explore the effectiveness of adding textual explanations to Parsons problems to improve instructional benefits.

  Large language models (LLMs) may offer a solution by allowing students to produce on-demand Parsons problems. In this paper, we introduce PuzzleMakerPy, an educational tool that uses an LLM to generate unlimited contextualized drag-and-drop programming exercises. We evaluated PuzzleMakerPy by deploying it in a large introductory programming course, and found that the ability to personalize the contextual framing was highly engaging for students.

• Understanding the Effects of Using Parsons Problems to Scaffold Code Writing for Students with Varying CS Self-Efficacy Levels [7.277912553209182]
  We investigated the impact of using Parsons problems as a code-writing scaffold for students with varying levels of CS self-efficacy. For students with low CS self-efficacy levels, those who received scaffolding achieved significantly higher practice performance and in-practice problem-solving efficiency. Students with higher pre-practice knowledge on the topic were more likely to effectively use the Parsons scaffolding.

  We introduce a scaffolding framework based on pop quizzes presented as multi-choice programming tasks. To automatically generate these pop quizzes, we propose a novel algorithm, PQuizSyn. Our algorithm synthesizes new tasks for pop quizzes with the following features: (a) Adaptive (i.e., individualized to the student's current attempt), (b) Comprehensible (i.e., easy to comprehend and solve), and (c) Concealing, do not reveal the solution code.
