Collaborative Research: Promoting a Growth Mindset Using Automated Feedback

“使用自动反馈促进成长心态”项目将开发和评估一种新的策略，用于在编程作业中生成自动反馈，这将为学生提供更受欢迎的体验，并认可他们在解决方案上所付出的努力。该项目的目标是促进“成长心态”的采用，即相信一个人的能力会通过练习和努力工作而提高，这与一系列改善的教育成果有关。该策略将包括四个关键思想：评估学生努力程度的测量方法；使用非积分奖励来奖励努力和认可努力工作的积极强化；学生代码的热图，以突出bug所在的位置；还有一种策略，可以清楚地确定学生需要解决的首要问题，以便取得进步。在项目的第一年，所有三所学校将使用现有的“传统”反馈方法收集基线数据。新的反馈干预将在项目的第二年和第三年进行评估。将收集和分析定量和定性数据，以检查成绩和学生行为的变化。混合方法数据收集计划将通过文献回顾和研究人员在教学这些课程中的直接经验对定量和定性数据进行三角测量，以得出有关研究问题的结论，并为设计可扩展和可复制的干预措施提供框架，以提高学生在编程项目中的表现。

The "Promoting a Growth Mindset Using Automated Feedback" project will develop and evaluate a new strategy for generating automated feedback on programming assignments that will provide a more welcoming experience for students, recognizing the effort they put in as they work on solutions. The goal of the project will be to promote the adoption of a "growth mindset" - a belief that one's abilities will improve with practice and hard work, which is associated with a range of improved educational outcomes. This strategy will encompass four key ideas: a measurement approach for assessing student effort; the use of non-points-based bonuses to reward effort and recognize hard work for positive reinforcement; heat maps of student code to highlight where bugs are located; and a strategy for clearly identifying the top priority for students to tackle in order to make progress. During the first year of the project, all three schools will collect baseline data using existing "conventional" feedback approaches. The new feedback intervention will be evaluated in years two and three of the project. Quantitative and qualitative data will be collected and analyzed to examine changes in performance and students' behavior. A mixed-method data collection plan will triangulate the quantitative and qualitative data with the review of literature and the researchers' direct experience in teaching these courses to reach conclusions regarding research questions of the study and provide the framework for the design of a scalable and replicable intervention to improve students' performance in the programming projects.
