Computer Science (31)This project addresses student learning obstacles and low motivation in introductory programming courses. This project utilizes two effective instruction methodologies, the cognitive apprenticeship learning (CAL) model and cognitive tutors (CT), to improve student problem solving skills with fundamental programming concepts, such as basic statements, if/switch statements, loops, and functions. There are two steps involved. First, task analysis of expert problem solving process is conducted and scaffolding techniques are developed. Second, computer tutor programs are constructed and delivered online. These tutoring programs interact with students as their personal coaches. They utilize explicit expert problem-solving processes and scaffolding techniques to guide students through their problem-solving practice. The tutors can accommodate multiple solution paths that students might choose for solving a problem. As students work through program-writing problems, the tutors provide step-by-step feedback and upon the student's request will provide advice on what to do next. Therefore, the student can always reach a successful conclusion to problem solving.Evaluation is conducted based on collected test scores for students in the first introductory programming course over a four-semester period. Pretest-posttest two-group control group design methodology is used for evaluation.

计算机科学（31）这个项目解决了学生在入门编程课程的学习障碍和低动机。该项目利用两种有效的教学方法，认知学徒学习（CAL）模型和认知导师（CT），以提高学生解决问题的能力与基本的编程概念，如基本语句，如果/开关语句，循环和函数。有两个步骤。首先，专家问题求解过程的任务分析和支架技术的发展。第二，计算机辅导课程的建设和在线交付。这些辅导项目与学生互动，作为他们的私人教练。他们利用明确的专家解决问题的过程和脚手架技术，通过他们的解决问题的实践指导学生。导师可以容纳学生可能选择解决问题的多个解决方案路径。当学生解决程序编写问题时，导师会提供一步一步的反馈，并根据学生的要求提供下一步该怎么做的建议。因此，学生总是能够成功地解决问题。评估是根据学生在四个学期的第一次入门编程课程中收集的考试成绩进行的。采用前测-后测两组控制组设计方法进行评价。
