Bootstrap：代数是一个课程模块，旨在将入门计算整合到代数课程中;该模块旨在帮助学生提高州和国家代数标准的各种基本学习成果。在之前的工作中，我们发表了关于学生在使用Bootstrap后在代数问题上的表现增益的初步研究结果。虽然结果是有希望的，但数据集并不大，并且学生们正在处理用Bootstrap的教学法搭建的代数问题。本文报告了一个更详细的研究与（a）数据从三倍以上的学生，（B）分析性能的变化，不正确的答案，（c）的一些问题，其中Bootstrap脚手架已被删除，（d）的IRT分析Bootstrap的程序设计教学法的元素。我们的研究结果证实，学生提高代数字问题完成模块后，即使在unscaffolded问题。在Bootstrap之后，符号形式问题的错误答案的性质似乎也有所改善。
Bootstrap:Algebra is a curricular module designed to integrate introductory computing into an algebra class; the module aims to help students improve on various essential learning outcomes from state and national algebra standards. In prior work, we published initial findings about student performance gains on algebra problems after taking Bootstrap. While the results were promising, the dataset was not large, and had students working on algebra problems that had been scaffolded with Bootstrap's pedagogy. This paper reports on a more detailed study with (a) data from more than three times as many students, (b) analysis of performance changes in incorrect answers, (c) some problems in which the Bootstrap scaffolds have been removed, and (d) an IRT analysis across the elements of Bootstrap's program-design pedagogy. Our results confirm that students improve on algebraic word problems after completing the module, even on unscaffolded problems. The nature of incorrect answers to symbolic-form questions also appears to improve after Bootstrap.
