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…

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,…

Describes a two-week lesson on electric fields that combined lecture, interactive video, lab experimentation, computer spread sheets, and computer-assisted-graphing. (PR)

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…

This interpretive case study describes a collaborative project involving a physics professor and a science educator. We report what was learned about factors that influenced the professor's development of teaching strategies, alternative to lecture, that were intended to promote prospective teachers' meaningful learning and their use of canonical…

Study investigated whether the use of videotaped models demonstrating effective teaching strategies in an elementary science lesson would promote increased use of effective questioning strategies among preservice teachers (n=38). Results show that the use of the videotaped teaching models increased the use of high-level, divergent,…
