Describes the development of a two-week National Science Foundation (NSF)-funded course at the Virginia Military Institute to promote the lecture demonstration technique. (SK)

Describes the application of the Piaget-based learning cycle technique for teaching an introductory organic chemistry course. Explains the step-by-step process used to convert a lecture course into a discussion-based active learning course. A learning cycle provides students with concrete material and aids them in understanding abstract concepts…

An experiment was conducted that compared the teaching effectiveness of a computer assisted instructional module and a lecture-discussion. The module, Predator Functional Response (PFR), was developed as part of the SUMIT (Single-concept User-adaptable Microcomputer-based Instructional Technique) project. A class of 30 students was randomly…

A new technique described as computer augmented lectures (CAL) is being used at the University of Texas at Austin. It involves the integration of on-line, interactive, time sharing computer terminals and theater size video projectors for large screen display. This paper covers the basic concept, pedagogical techniques, experiments conducted,…

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)

Surveyed 1200 students in a second semester general chemistry course at Purdue. Investigates areas where student and faculty perceptions of the content of chemistry courses differ. Elaborates on each area and suggests explanations for the findings involved. (MVL)

Using data from a national study of instructional practices in 7th- through 8th-grade science classes, this study examined a subset of Christian school teachers to determine what instructional practices predominated in Christian-school science classes. Results indicated that participants used 10 teaching methods (six constructivist and four…

We carried out an experiment to determine whether student learning gains in a large, traditionally taught, upper-division lecture course in developmental biology could be increased by partially changing to a more interactive classroom format. In two successive semesters, we presented the same course syllabus using different teaching styles: in…

A learning cycle consists of three phases: exploration; conceptual invention; and expansion of an idea. These phases parallel Piaget's functioning model of assimilation, disequilibrium and accomodation, and organization respectively. The learning cycle perceives students as actors rather than reactors to the environment. Inherent in that…

Three assessments of the status of school science discovered that textbooks frequently determine course content, the preparation science provides for next academic level is its justification, lecture method is widely used, science is a low educational priority, and students feel it is irrelevant to later life experiences. (MBR)

Four different methods of teaching--cooperative learning, class discussions, concept maps, and lectures--were integrated into a freshman-level general chemistry course to compare students' levels of participation. Findings support the idea that multiple modes of learning foster the metacognitive skills necessary for mastering general chemistry.…

The discussion board feature that is included with most course management software packages is a potentially valuable tool to augment instructor-student interactions in science lecture courses and increase student motivation. However, many teachers seem to have been frustrated that students do not readily make use of this feature when it is added…

We developed a hybrid course format (part online, part face-to-face) to deliver a high-enrollment, introductory environmental biology course to resident (living on or near campus), non-science majors at a large, public university. The hybrid course was structured to include bi-weekly online assignments and weekly meetings in the lecture hall…

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…

There is much information from educational psychology studies on how people learn. The thesis of this paper is that we should use this information to guide the ways in which we teach rather than blindly using our traditional methods. In this context, problem-based learning (PBL), as a method of teaching widely used in medical schools but…
