For some elementary science teachers, a unit on land and water brings nightmares of dirt and water all over the room. Several Earth science "kits" contain hands-on exercises that allow the students to "get messy" as they manipulate materials; however, these lessons may lack the necessary opportunities for students to ask unique…

In general, laboratories are exercises with a primary focus on the verification of established laws and principles, or on the discovery of objectively knowable facts. In laboratories, students gather data without comprehending the meaning of their actions. The cognitive demand of laboratory tasks is reduced to a minimal level. To prevent these…

This article reports on the qualitative aspects of a study that examined whether introducing a "Problem-based Learning" ("PBL") approach in a one-year foundation programme can create conditions for learners to develop and sustain self-directed learning skills. This interpretive constructivist case study was located in…

If our chosen aim in science education is to be inclusive and to improve students' learning achievements, then we must identify teaching methodologies that are appropriate for teaching and learning specific knowledge. Karagiorgi and Symeo (2005) remind us that instructional designers are thus challenged to translate the philosophy of…

Problem-based learning (PBL) is a constructivist method of instruction aligned with the science educational reform movement to increase scientific literacy for all Americans. As such, PBL instruction is an increasingly popular topic for professional development workshops offered to teachers in secondary learning environments. This research…

Researchers are skeptical about the role of authoritative sources of information in a constructivist learning environment for fear of usurping students' critical thinking. Taking a social semiotics perspective in this study, authoritative sources are regarded as inscriptions of cultural artifacts, and science learning involves meaning-making of…

One of the challenges higher education institutions face is to effectively endow science primary teachers with competences on "how", "where", "when" and "whether" to use technological resources (software and hardware) in teaching contexts. Teachers' Technological Pedagogical Content Knowledge (TPCK) requires…

Focuses on problem-based learning (PBL). Explains ill-defined problems of PBL and compares PBL with the typical problem solving approach. Lists 10 steps to involve students in constructing understanding for use with PBL. (YDS)

Discusses the problem based learning (PBL) environment and positive and negative factors affecting the implementation of PBL in K-12 education. Identifies and examines design guidelines for PBL. (Contains 23 references.) (YDS)

In this study, with selecting the focusing point of the problem as the availability of cartoons, the teaching of global environmental problems according to the constructivist theory is investigated on the 7th graders in rural areas. This study is restricted with the global warming (G), ozone depletion (O) and the acid rain (A) problems. In the…

This document identifies five types of learning experiences which are relevant to understanding students' understanding of concepts and principles. These include exploring existing concepts, honing and clustering concepts, developing analytical and reasoning skills, developing problem solving skills, and structuring knowledge in memory. Each of…

This paper identifies five types of learning experiences which are relevant to understanding students' grasp of concepts and principles. These include exploring existing concepts, honing and clustering concepts, developing analytical and reasoning skills, developing problem solving skills, and structuring knowledge in memory. Each of these…

In the Discover Lab, a science education center at the State University of New York at Stony Brook, students learn to investigate, critique, and test big scientific questions and devise their own answers. Students are guided through cyclical processes of inquiry, logic and reasoning, testing and experimentation, and communication. (MLH)

This self-study was designed to explore problem-based learning (PBL) as an instructional approach in the context of a pre-service science education methods course. Through the development and implementation of PBL curriculum, the author's goals were to improve her classroom practice and her understanding of that practice, to contribute to the…

Describes action research on the efficacy of problem-based learning using a hermeneutic dialectic methodology. Focuses on the emergence of students' critical-thinking skills, the relevance of science concepts taught, the interdisciplinary nature of the problems addressed, and the changing roles of the teacher and students. Reports that the course…
