A teaching team composed of a faculty member (lecture) and a graduate teaching assistant (lab) endeavored to engage students enrolled in several sections of the same organic chemistry course through the use of social media. Students were encouraged to follow both instructors on Twitter and were asked to share aspects of the class using the social…

Several active-learning pedagogies involve groups of students working together to construct their own understanding of course content. In these classrooms, the instructor serves as a facilitator of learning, by interacting with every group, engaging students in discussions, answering questions, and providing formative feedback. This type of…

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)…

This paper presents a model for teaching large classes that facilitates a "small class feel" to counteract the distance, anonymity, and formality that often characterize large lecture-style courses in higher education. One author (E. P.) has been teaching a 300-student general education critical thinking course for ten years, and the…

This paper provides a brief review of blended learning as a didactic method, and discusses the issues and challenges of using blended learning models in post-secondary education. Blended learning refers to mixed modes of instruction that combine traditional face-to-face classroom teaching methods and online learning materials. The paper will…

The typical "Astro 101" lecture-based course is passive, and adding well-designed learner-centered labs allows students to experience science as a pattern of thought. In this article, we present an approach to developing an introductory lab course. Identification of goals and student outcomes, particularly skills, and process and attitudinal…

Ideally, college classes are small. Kilgore and Cook (2007) observed that large class size can be an obstacle to good teaching. However, there is financial and human resource value in delivering quality course content in large lectures. Consequently, large lecture classes are a fundamental part of the undergraduate student experience at many…

Describes an undergraduate general education course offered at Harvard College during the 1950s and 1960s. Looks at the course's use of lectures, section meetings, and term papers. Emphasizes the mutual learning of the undergraduates and their graduate section leaders, course content, and adjustments to changing student attitudes and temperaments.…

Describes ten common technical mistakes most graduate teaching assistants make while teaching, such as projecting a weak presence, relying too heavily on their notes, posing vague questions, and not reinforcing student participation. Offers suggestions for correcting the mistakes. States that faculty might want to monitor their own teaching…

Biology students in their first year at university have difficulty understanding the abstract concepts of photosynthesis. The traditional didactic lecture followed by practical exercises that show various macroscopic aspects of photosynthesis often do not help the students visualise or understand the submicroscopic (molecular-level) reactions that…

Lecture is a common presentation style that gives instructors a lot of control over topics and time allocation, but can limit active student participation and learning. This article presents some ideas to increase the level of student involvement in lecture. The examples and suggestions are based on the author's experience as a senior lecturer for…

A study of the communication skill needs of the foreign teaching associate (TA) in American universities focused on two questions: (1) What does a foreign TA do to communicate information in an American classroom in terms of comunication strategies and devices for cohesion and coherence of discourse? and (2) How does this compare with the way an…

Large lecture classes can often be quite impersonal. Creating a teaching team, consisting of the instructor, graduate assistants, and a few undergraduates, is one of the ways the University of Arizona has adopted in order to make the large lecture class more personal. As members of the Department of Mathematics we train the undergraduates, who are…

The experiences of a chemistry professor and a physics professor at a regional branch campus of Penn State University are described. In both instances, the faculty members had previously served as teaching assistants at a research intensive institution, the University of Illinois at Urbana-Champaign. The unique pedagogical struggles involved in…
