Table 1.

Student evaluation of the benefits of the lab session. As part of routine course evaluations, students were asked whether the lab session was “beneficial and contributed to overall learning” using a Likert-type scale of 1 (strongly disagree) to 5 (strongly agree). The percent of responders indicating “Agree” or “Strongly Agree” was recorded in addition to the average response each year, relative to the total number of responders for that specific question. The mean Likert scale score for each year was also noted
