A comparison of student performance in an introductory biology class that used a lecture-based approach (N = 15 classes; 462 students) with those that had a no-lecture approach (N = 9 classes; 238 students). All classes were taught by the principal researcher. In the no- lecture environment, shifts in student perceptions of science were…

This qualitative study compares the views about nature of science (NOS) between students enrolled in a traditional lecture and laboratory course and students in an inquiry-based class to the view of the scientists who taught the course. We administered the Views of Nature of Science Form C (VNOS-C) to identify students' views after partaking in…

Students come into the classroom with a variety of background knowledge. Therefore, it is imperative that educators are able to help all students, regardless of their familiarity with the content. Since it can be challenging for some large enrollment classes to schedule recitation classes after lectures due to logistical constraints, this study…

This column shares reflections or thoughtful opinions on issues of broad interest to the community. This month's issue discusses the value of traditional lecturing.

This article reports on an investigation into the correlations between students' understandings of introductory astronomy concepts and the correctness and coherency of their written responses to targeted Lecture-Tutorial questions.

In very large lecture classes, student engagement is always a challenge, and many instructors use electronic student response systems (SRS) to promote student engagement and active learning. The conventional wisdom in using student response systems is that the technology matters less than the pedagogy; it is the added value of the instructor that…

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…

Multiple national reports have pushed for the integration of quantitative concepts into the context of disciplinary science courses. The aim of this study was to evaluate the quantitative and statistical literacy of biology students and explore learning gains when those skills were taught implicitly in the context of biology. I examined gains in…

A case that reads well on paper can absolutely fail in the classroom unless the faculty member is up to the task. This article focuses on why the teaching notes are vital to the success of a case, and how they are often more difficult to write then the case story itself. It is in the notes that the reader can see what the writer was trying to do.…

Engaging students, checking for understanding, and encouraging oral participation are ongoing pedagogical challenges in large lecture courses. In this study, the instructor used notecard-facilitated cold-calling as a means of encouraging attendance and participation in a large-lecture biology class.

We describe how a practical instructional development process helped a first-year assistant professor rapidly develop, implement, and assess the impact on her Analytical Chemistry course caused by three changes: (a) moving the lab into the same semester as the lecture, (b) developing a more collaborative classroom environment, and (c) increasing…

The authors present the findings of a small-scale study of student opinions drawn from an anonymous and voluntary survey in an undergraduate science classroom. The survey questions focused on the use of basic tools in a college classroom. The tools included in the survey were PowerPoint, overhead projectors/chalkboards, personal response units,…

Introductory science courses play a critical role in the recruitment and retention of undergraduate science majors. In particular, first-year courses are opportunities to engage students in scientific practices and motivate them to consider scientific careers. We developed an introductory course using a semester-long series of established…

At the authors' public liberal arts institution, biology masters students are required to enroll in BIOL 5050: Teaching Techniques. Course topics include designing effective lectures, assessment, classroom management, diversity in the classroom, and active learning strategies. The impact of this type of training on graduate students' attitudes and…

Large-enrollment undergraduate science courses are often seen as "gatekeepers" and tend to support less-than-ideal pedagogical approaches. Student satisfaction with teaching and learning and gains in student conceptual understanding in these courses is often limited at best. At University of Colorado Denver, the Learning Assistant (LA)…
