Studies on the effectiveness of clickers in undergraduate chemistry courses are mixed, and there is disagreement on how to effectively leverage clickers to improve student learning performance. To fill a gap in the research, we analyzed three different teaching strategies (two involving clickers) in a General Chemistry I course over a 13-year time…

Critical thinking skills are sought after in the workforce and are often included in course, departmental, and programmatic learning objectives. However, in the curriculum of many courses we tend to focus on content rather than on fostering the growth of the cognitive skills needed to improve critical thinking ability. Further, skills are…

This case study outlines the use of multilevel modeling for meta-analysis to analyze the meta-analytic data for a 3-year project. The focus of the project, which was funded by the National Science Foundation, was on comparing the performance (achievement) of undergraduate students who were taught using one of the various types of active…

We compare student learning and perception data from astronomy, physics, and geology courses taught in a traditional classroom with individual desks to the same classes taught in a large auditorium. In a large student sample (1,593 students), there is no clear difference between rooms in measures of failure rates or average final grades. However,…

One critical element of increasing science literacy is student engagement. In this article, I report on the impacts of changing an introductory environmental science class to move away from standard lecture delivery and increase student engagement in science. The class was designed around small-group activities, inquiry labs, and substantial use…

We report the results of a study designed to investigate the effectiveness of peer-led, small-group discussions in a large (N greater than 400) general chemistry course usually taught in a traditional lecture format. The administrative structure, the training of the peer facilitators, and the achievement of students exposed to this environment…

This paper describes the development and evaluation of a blended learning resource in the biosciences, created by combining online learning with formal face-face lectures and supported by formative assessments. In order to improve the effectiveness and efficiency of teaching large classes with mixed student cohorts, teaching was delivered through…

An experimental study was designed to study the effectiveness of Problem Based Learning (PBL) in the context of higher education in an urban-city university in Lima, Peru. In the fall semester of 2004, eleven sections of Chemistry 1 were offered to first year students in the College of Science at this University. In six of these eleven sections…

College physics teachers describe their experience using a computer-based classroom communication system that facilitates presentation of questions for small-group work, collection of student answers, and display of histograms showing how the class answered, all feeding into classwide discussions. The technique engages students in active learning…
