Gaining Insight into Students' Thinking through Assessment Tasks
Keyword(s):
The task in Figure 1A, which was given to middle school students, asked them to find the number of dots in the twentieth step of the pattern. As shown in figure 1b, the answers that students gave ranged from 20 dots to well over 60 million dots. If your students gave these answers without providing work or explanations, would you be able to tell how they obtained them? Probably not. Without looking closely at the students' work or explanations or talking to them about their solution strategies, it is difficult to understand how they were thinking about the pattern task and how their thinking could have produced such a wide range of answers.
