Figure 8.

Comparison of student responses on the 20 learning gain items (mean and SEM) from the SURE survey. The data are classified by instructor reports of the number of hours devoted to the annotation project. These were divided into four quartiles as shown in Figure 7; the responses from the Q1 (1–10 h) and Q4 (>36 h) students are shown here. The Q1 group includes 86–112 observations; the Q4 group includes 149–175 observations. (Respondents tallied here were those who answered the specific question on the SURE survey.) Error bars represent 2 SEM.
