Recently, there has been a push within engineering curricula to adopt more learner-centered pedagogies, such as case-based instruction. Case-based instruction has been hypothesized to make the curriculum more relevant and motivating for students by pushing them to integrate the concepts they have learned with other experiences. The current study…

This quasi-experimental, mixed methods study examined the transfer of a well-established pedagogical strategy, Peer-Led Team Learning (PLTL), to an online workshop environment (cPLTL) in a general chemistry course at a research university in the Midwest. The null hypothesis guiding the study was that no substantive differences would emerge between…

Poor instruction has been cited as a primary cause of attrition from STEM majors and a major obstacle to learning for those who stay [Seymour and Hewitt [1997]. Talking about leaving: Why undergraduates leave the sciences. Boulder, CO: Westview]. Using a double-blind design, this study tests the hypothesis that the lack of explicit instructions in…

We conducted a laboratory-based randomized control study to examine the effectiveness of inquiry-based instruction. We also disaggregated the data by student demographic variables to examine if inquiry can provide equitable opportunities to learn. Fifty-eight students aged 14-16 years old were randomly assigned to one of two groups. Both groups of…

Our main goal in this study was to determine whether the use of computer animation and illustration activities in high school can contribute to student achievement in molecular genetics. Three comparable groups of eleventh- and twelfth-grade students participated: the control group (116 students) was taught in the traditional lecture format,…

Explores the types of written questions students ask after reading one or more chapters from a textbook and investigates students' ability to improve their questions during the course of a single semester. Examines two comparable populations, undergraduate students who were taught in the traditional lecture format and students who were taught in…

Investigated preservice physics teachers' ability to make judgments of observed teaching during one of two courses. Students in an inductive course (N=24) engaged in peer teaching before receiving instruction in theory. Students in a deductive course (N=26) received instruction in theory before peer teaching.

Students in classes using a self-instructional unit on meteorology and climatology which provided research data from which generalizations could be drawn increased their critical thinking skills more than groups using conventional earth science texts but did not differ significantly in performance on an achievement test. (AL)

A Biological Sciences Curriculum Study (BSCS) inquiry approach for university general biology laboratory was tested against a well-established commercial program judged to be highly directive. The BSCS was found to be more effective in learning biology laboratory concepts than the commercial program as measured by a laboratory concepts test.…

Science curriculum evaluation studies (1963-1978) were examined to assess impact of innovative curricula compared with traditional curricula on student learning outcomes. Results suggest students in secondary school science courses scored moderately better than students in traditional courses on innovative and neutral tests and negligibly lower on…

"Hands-on" activities play an important, but controversial, role in early science education. In this study we attempt to clarify some of the issues surrounding the controversy by calling attention to distinctions between: (a) type of instruction (direct or discovery); (b) type of knowledge to be acquired (domain-general or domain-specific); and…

Determined differences between lecture-demonstration and small-group laboratory approaches on students' (N=74) chemistry achievement and attitudes toward science. Findings indicate that students taught by the laboratory approach achieved better on immediate/delayed posttests than students taught by lecture-demonstration method. More desirable…

Summarizes results of the meta-analysis of 105 research studies dealing with effects of new science curricula on student performance. Twenty-seven different new science curricula involving one or more measures of student performance were included in the analysis. Positive performance patterns were found in all new curricula examined. (JN)

Compared effectiveness of discovery and expository instructional strategies on science knowledge and attitudes of fifth-grade Egyptian students (N=276). Although there were no sex differences, students taught by discovery scored higher in achievement (recall and application) and attitudes than those taught by the expository method. (JN)

Two approaches to the content of thermodynamics were used in an introductory college physics course: traditional organization and organization based on Ausubel's learning theory. The influence of these organizations on engineering student's (N=58) cognitive structure was investigated using a word association test analyzed through hierarchical…
