Many national science frameworks (e.g., Next Generation Science Standards) argue that developing mathematical modeling competencies is critical for students' deep understanding of science. However, science teachers may be unprepared to assess these competencies. We are addressing this need by developing virtual lab performance assessments that…

This paper reports on data collected via an audience response system, where a convenience sample of 300 adults aged 17-50 pressed a button to register their answers for twenty multiple choice questions. The responses were then discussed with the respondents at the time. The original dataset includes physics, biology and chemistry questions. The…

Systems used for the management of learning and strategies students use to answer tests are highlighted. (Author/EJS)
