本文报告了一项实验，其中明确鼓励一年级编程学生在多项选择题中跟踪代码时使用对象（实例）图。我们推测，通过在这种技术中提供脚手架，将帮助学生更好地理解代码，然后他们将继续在类似的情况下绘制自己的图表。事实证明并非如此。虽然通常绘制图表的学生在测试他们对代码行为和对象引用的理解的问题上表现更好，但我们的干预似乎并没有帮助学生，而且接受干预的学生也不太可能继续自己使用该技术。
This paper reports on an experiment in which first year programming students were given explicit encouragement to use Object (Instance) diagrams when tracing code in multiple-choice questions. We conjectured that by providing scaffolding in this technique, students would be helped to understand the code better and that they would then continue to draw their own diagrams in similar situations. This turned out not to be the case. Although generally students who draw diagrams do better in questions that test their understanding of code behaviour and object referencing, our intervention does not appear to have helped students and the students who were exposed to the intervention were not more likely to go on to use the technique themselves.
