Conclusions about the effectiveness of the course differ based on which data are used. (A) The conclusion from only examining the data from the volunteers in the research-based course is that students show gains in both confidence in lab-based tasks and interest in pursuing future research. (B) The conclusion from comparing the volunteers in the research-based course with non-volunteers in the cookbook course is that students in the research-based course show higher gains than those in the cookbook course. (C) The conclusion from assessing non-volunteer students in the research-based course is that students show gains in confidence but no gains in interest. (D) The conclusion from comparing non-volunteers in the research-based course to non-volunteers in the cookbook course is that there are no differences between the students in interest or confidence in their ability to do lab-based tasks.
