This study assessed the impact that reflective journals used in an introductory college science course had on preservice teachers' science literacy. Fourteen preservice teachers enrolled in an introductory physical science course taught using a variety of constructivist instructional methods (hands-on activities, cooperative group work,…

This paper documents a 3-year longitudinal study designed to track changes in preservice teachers' attitudes toward teaching and learning mathematics and science while enrolled in an Urban Preservice Degree Articulation in Teacher Education (UPDATE) Project. The primary goal of this project was to provide a pathway for urban para-educators of…

This paper addresses the issue of effectively integrating technology such as the World Wide Web and computer software technology into diverse classrooms. Significant ideas and support for constructivist, project-based teaching and learning approaches are also provided. This paper argues for schools, universities, and departments of education…

This study reports on the effects of a major reform initiative which was implemented in the Iowa City Community Schools District. The Science: Parents, Activities, and Literature (Science PALs) Project was launched in 1994 to reform the district's elementary science program. It was designed to increase teacher effectiveness by providing a…

This paper describes an intergenerational science program called Sisters in Science which fosters girls' interest and achievement in science. The program is designed to encourage and prepare girls and women for careers in math, science, and technology. A group of fourth grade girls from 19 classrooms across 6 elementary schools met once a week…

This study investigated whether seventh- and ninth-grade students who did prewriting activities in English class preceding a related literature comprehension test would produce higher raw test scores on literal and interpretive questions than would students who did not use prewriting. The study took place in 1993 and 1995. Participants included…

The nature of science encompasses the entire world and within that realm, patterns of life can be observed, interpreted, and organized into a sensible arrangement of understanding. By discovering, through an intricate process, how shapes and images form into a complete design or sequence, students related similar scientific patterns to their own…

This paper reports on some early findings from an assessment of the impact of mathematics and science reforms in Chicago, Illinois, Memphis, Tennessee, Miami, Florida, and El Paso, Texas. These reforms have been part of the National Science Foundation's Urban Systemic Reform program. Standards-based curriculum and instructional approaches with a…

Describes six divergent forms of constructivism in providing an overview of constructivist theory. Suggests a scheme for characterizing constructivist writing on the basis of its relative emphasis on personal versus social construction of knowledge, and objectivist versus relativist views of the nature of science. Contains 31 references. (DDR)

Argues that some forms of constructivism propose an epistemological idealism with a concomitant relativism, while other forms are explicitly opposed to such positions. Explains that all forms of constructivism are often presented as being relativistic. Contains 31 references. (DDR)

Examines central parts from the first two papers in this journal by Peter Slezak criticizing the "sociology of scientific knowledge". Considers some of the main philosophical issues raised by sociologists of science. Contains 87 references. (DDR)

Discusses misconceptions about constructivism by identifying related myths such as students should always be actively and reflectively constructing, manipulatives make learners active, and cooperative learning is constructivist. One central goal of constructivism should be that students become autonomous and self-motivated in their learning.…

Describes how the current mathematics education reform principles are implemented in a third-grade classroom. Focus areas include how to conduct whole-group discussion and examination of children's thought processes. (AIM)

The eight chapters of this theme issue describe studies of learning environments conducted in a variety of conceptual and methodological perspectives by researchers in the United States, Canada, Australia, and the Netherlands. Studies reflect perspectives on conceptualizations of learning environments that range from objectivist to more…

Discussion of constructivist learning environments focuses on the concept of grounded design, a process that involves linking the practices of learning systems design with related theory and research. Topics include directed versus situated learning environments, situated cognition and anchored instruction, social constructivism and problem…
