In this article, the author introduces the usage of case studies to be an excellent method for engaging students through stories. The author notes she developed a series of mini-case studies that can be implemented, with a little advance preparation, within a 10- to 15-minute window during lecture. What makes them "mini" case studies?…

Learning takes place mostly through communication. This is why teachers employ different types of interaction in the classroom in order to provide a varied environment for the students. Apart from the commonly used Student-Teacher-Talk or Teacher-Student-Talk, presentations or lectures may offer advantages with regard to the promotion of…

Problem-based learning can enhance reasoning and concept development among undergraduate college students by presenting content within authentic contexts. However, large lecture sections present problems and barriers to implementing PBL. This article discusses approaches used by the author to infuse PBL into large biology lecture sections, and…

The cAcL[subscript 2] approach (concept Advancement through chemistry Lab-Lecture) incorporates three major educational methodologies into one: a student-centered approach, the full integration of lecture and laboratory formats, and hands-on activity based-instruction. This format has been tested for cognitive and attitudinal gains in students and…

Anyone who has taught a lecture to a large group of students has probably experienced undesirable student behaviors. The author, who has taught an introductory college biology course at Syracuse University for 45 years, relates that an important part of his teaching philosophy is that everyone should learn from everything that they do, and…

Points out that second-language learners, females, low-income students, and students of color sometimes experience difficulties and struggle with science instruction. Describes the interactive lecture in which students use critical thinking skills and suggests possible techniques that teachers can use when conducting an interactive lecture. (YDS)

Lists postulates on which the author bases his approach to large class instruction. Suggestions are given for such administrative, operational, and academic procedures as organizing handouts and class information; avoiding "busy work"; finding out about the students (personal and academic); making an assignment due every class; and providing quick…

Reports a classification of expository teaching styles of biology, chemistry and integrated science teachers in Nigeria. No evidence was found of pupil-pupil interaction in any of the lessons observed. Compares results with other studies from Britain, Canada, and Indonesia and indicates significant differences. (CW)

To determine the effect of collaborative learning methods on the success rate of physics students at Northern Maine Technical College (NMTC), a study was undertaken to compare the mean final exam scores of a students in a physics course taught by traditional lecture/lab methods to those in a group taught by collaborative techniques. The…

Describes and evaluates a technique used in two science lecture courses (biochemistry and introductory meteorology), in which lectures were interspersed with frequent, brief discussions within spontaneously formed small groups. Some differences were found in the ways the two professors managed the technique, but both felt in-class participation…

Presented are studies which confirm the idea that factors related to the format, the order of items presented, and the presentation style can affect the impact of information and student recall. Discussed are dynamic presentations, enumerated items, impact and timing, pairing of items, data summaries, and information load. (CW)

Courseware was developed to facilitate knowledge transfer between lecture and laboratory for general chemistry at the University of Notre Dame (Indiana). One project uses a tutorial strategy. Another uses tool-based courseware for modeling and manipulation of simulated representations of chemical systems; worksheets guide student use of courseware…

Reports on a study intended to compare the effects of two methods of instruction designed to teach preservice elementary teachers to acquire and retain integrated science process skills. Results indicated that the self-instructional method was significantly more effective than the teacher-directed method. (TW)

Forms and characteristics of small group physics instruction in the Russian university are examined and in some cases, compared to those used in Britain. Topics discussed include the lecture method, classroom communication during lectures, postlecture discussion, specialized small-audience lectures, problem solving, individual research projects,…

In its use of complex, real-world problems to introduce concepts and motivate learning in an active and cooperative learning environment, problem-based learning is a powerful alternative to the passive lecture in introductory college science. Use of technology and multimedia instruction, focus on large classes, and use of interdisciplinary…
