A distinguishing feature of all the formative assessment probes in the "Uncovering Student Ideas" series is that each probe has two parts: (1) a selected answer choice that usually mirrors the research on commonly held ideas students have about concepts or phenomena; and (2) an explanation that supports their answer choice. It is this…

The study describes a new methodology and learning cycle, which will give a better understanding of the periodic table to the students. The students following the cycle have now started focusing more on the chemical instead of physical properties when developing their schemes.

Describes exploratory activities for a young child seeking to become acquainted with the world in which he lives. (EB)

Presents an exploratory experience that allows students an opportunity to practice science process skills and use all of their senses. Describes a fruit study activity, appropriate for grades three through six, that incorporates the learning cycle (exploration, concept development, and concept application) and cooperative learning strategies.…

Correlates the kinds of strategies associated with a deep approach to learning science. Analyzes the interactions of two groups of grade 8 students while they were engaged in hands-on science activities during instruction in a chemistry unit. Focuses on two students who showed a deep approach to learning. (Contains 47 references.) (Author/YDS)

Some ways in which exploratory activities of the preschool child involve science concepts are described. The role of adults knowledgeable about both science and child development is stressed. Emphasis is placed on hands-on experiences. (EB)

Reports on a study that explored the types of questions that students ask for open-ended science investigations. Discusses how teachers can help students identify problems and pose questions that are feasible for investigation. (Contains 55 references.) (DDR)

THIS VOLUME IS A COLLECTION OF EIGHT PAPERS DEALING WITH ASPECTS OF TEACHING PHYSICS TO RUSSIAN STUDENTS IN GRADES FIVE THROUGH ELEVEN. TOPICS OF PAPERS ARE (1) THE PRESENT SITUATION IN THE METHOD OF HIGH-SCHOOL PHYSICS AND ITS BEARING ON THE POLYTECHNICAL INSTRUCTION SYSTEM, (2) THE DEVELOPMENT OF RATIONAL THOUGHT IN STUDENTS DURING THE TEACHING…

Demonstrations are presented in which children can be introduced to evidence of specific concepts enabling them to participate in such a way that any conceptual conflicts that might arise in this learning situation can be gradually reduced. (EB)

Describes a scientific investigation of sexual dimorphism with regard to chela size in crayfish in which students utilize the skills, tools, and techniques associated with the formulation and testing of scientific hypotheses. Indicates that students find the investigation effective in aiding their understanding of fundamental aspects of scientific…

The material presented in this article is intended to help students learn how to learn. The seven key concepts of David Ausubel's assimilation theory for cognitive learning are discussed with reference to the classroom. Concept mapping is suggested as a tool for demonstrating how the seven key concepts function. (SA)

Examined are some of the distinctive features of the biological sciences. Discussed are the use of models with case studies, universal principles, and alternative frameworks. (CW)

Describes a study designed to compare student success in a concept mapping exercise with the cognitive preference of the student, and to determine whether students achieve better using individualistic or cooperative learning modes in the concept mapping exercise. Discusses the background, methodology and results. (CW)

This paper describes the design and results of a study carried out with elementary pupils ages 8-9 years on the topic of sinking and floating, with the aim of checking the validity of a general scheme for classroom activities based on a constructivist perspective. Children's "ways of looking" at buoyancy and the production of materials…

This paper discussed the use of structured observations as a research strategy in two recently completed studies that investigated students thought processes and behaviors in a microcomputer-based laboratory (MBL) environment and in other instrument-based laboratory environments. In the first study, students' behaviors and thought processes were…
