In the spring of 1988, the Massachusetts Department of Education administered its second biennial assessment (the Massachusetts Educational Assessment Program), testing students in grades 4, 8, and 12 in reading, mathematics, science, and social studies. This report discusses the use of open-ended questions in one form of the science tests.…

The Educational Technology Center (ETC) has devoted the last five years to studying ways of using the computer and other information technologies to teach understanding in science, mathematics, and computing in the nation's elementary and secondary schools. The Center's research has focused on targets of difficulty, topics and concepts that are…

Incorporating engineering in the elementary school curriculum provides students with ways of connecting, applying, and reinforcing knowledge in math, science, and design. To bring what is essentially a new discipline to K-12 education means developing and supporting new tools for the classroom, additional curriculum, teacher training, and support…

We have designed model-development sequences using a common context to provide authentic problem-solving experiences for first-year students. The model-development sequence takes a model-eliciting activity a step further by engaging students in the exploration and adaptation of a mathematical model (e.g., procedure, algorithm, method) for solving…

Students' conceptual understanding of Newton's third law has been the subject of numerous studies. These studies have often pointed out the importance of addressing the concept of interaction in teaching Newtonian mechanics. In this study, teachers were interviewed in order to examine how they understand interaction and use it in their…

Research in social psychology will be more useful to society if researchers incorporate evaluation research into their inquiries. Evaluation research is interpreted to include overall assessment of a program or project as well as methodological procedures used to assess implementation and outcome of social and cultural action programs.…

A science fiction unit on space designed for secondary schools is described and advocated in this article. This experimental program, presented to 9th grade students at University High School, State University of Iowa, provides a highly imaginative experience in literature while raising unique philosophical and moral problems not found in other…

This book offers broad, practical strategies for teaching science and engineering courses and describes how faculty can provide a learning environment that helps students comprehend the nature of science, understand science concepts, and solve problems in science courses. The student-centered approach focuses on two main themes: reflective writing…

Describes interdisciplinary activities for teaching elementary science using eggs. Each activity is designed to introduce larger thematic units. Activities include making egg animals (study of animal survival), throwing raw eggs at taut vertical sheets and making cars for egg passengers (force and momentum), and making eggshell domes (dome…

Presents findings from a case study of one fifth grade student's efforts to construct meaning in her science class during a unit on light. Contends that students' efforts to construct meaning may suggest instructional approaches that guide learners to consider and grasp scientific explanations while still valuing their own insights and abilities…

Describes Project ARTIST (Astronomy-Related Teacher Inservice Training). Using hands-on science experiences, an integrated curriculum, and translated materials, teachers can make space science accessible and interesting to elementary and middle school children. (ZWH)

Using ideas adopted from Project ARTIST (Astronomy-Related Teacher Inservice Training), a teacher develops a sixth-grade astronomy program which incorporates ancient folklore and sky stories from a variety of ethnic backgrounds. (ZWH)

The purpose of this article is to present various techniques that will engage young children, ages 3-8, in learning science and mathematics. Children actively engage in acquiring basic science and mathematics concepts as they explore their environment. The methods presented are intended to meet the developmental levels of young learners as they…

The Water and Molecular Networks (WAMNet) Project uses graduate student written Reduced Instruction Set Computing (RISC) computer simulations of the molecular structure of water to assist high school students learn about the nature of water. This study examined: (1) preconceptions concerning the molecular structure of water common among high…

One hundred and forty students in grades 6 and 7 were asked to process 32 science statements. Half of the statements were consistent with their prior knowledge, whereas the remaining facts were inconsistent with it. Half of the students were instructed to read the sentences for understanding (reading controls). The remaining students were…
