Development of an Integrated Educational Environment for both Learners and Teachers in Training of Algorithm and Programming

在这项研究中，我们构建了一个由支持学习者和支持教师的工具组成的算法与程序设计集成教育环境。对于学习者，我们构建了以下两个工具：(1)支持学习者对目标算法的理解的工具。(2)支持学习者理解目标算法与表示算法的程序代码之间关系的工具。对于教师，我们构建了以下两个工具：(1)支持学习者对目标算法的理解；(2)支持学习者理解目标算法与表示算法的程序代码之间的关系。对于教师，我们构建了以下两个工具：(1)支持学习者对目标算法的理解。(2)支持学习者理解目标算法与表示算法的程序代码之间的关系。对于教师，我们构建了以下三个工具：(1)从程序代码生成标准算法表示的工具。(2)支持教师对学习者的报告进行评分的工具。(3)对学习者程序进行自动分类的工具。我们还对这些工具进行了实验评估，发现这些工具具有预期的效果。

In this research, we construct an integrated Educational Environment for algorithm and programming that consists of tools supporting learners and ones supporting teachers.For learners, we construct the following two tools: (1) A tool supporting learners to externalize their understanding on a target algorithm.(2) A tool supporting learners to understand relation between the target algorithm and a program code which represents the algorithm.And for teachers, we construct the following three tools: (1) A tool generating a standard algorithm representation from a program code.(2) A tool supporting teachers to mark learners’ reports.(3) A tool classifying learners programs automatically.We also conduct experimental evaluation of the tools and we find the tools have expected effects.
