Uses a test to assess teachers' science knowledge and understanding and monitors change over two years of a primary science in-service program in 31 schools. Despite moves to improve primary science teachers' subject knowledge, many still held typical misconceptions. Concludes that teachers need a thorough understanding of interrelated concepts…

This study investigates student misconceptions in the areas of continent, ocean, permanence of ocean basins, continental drift, Earth's magnetic field, and plates and plate motions. A teaching-learning model was designed based on a constructivist approach. Results show that students held a substantial number of misconceptions. (Author/DKM)

Reports on a study designed to investigate secondary school students' misconceptions of conservation principles and fields. Results indicate that misconceptions appear to persist and that students were unable to transfer knowledge readily. Also teachers appear not to be fully aware of students' misconceptions. (ML)

Offers perspectives on research related to students' ideas about science prior to instruction. Discusses possible origins of prior knowledge, the requirements for conceptual change, and reviews instructional implications. (ML)

Reports on the procedure and results of the trial of support materials that were developed for primary teacher mentors to help trainee teachers improve their medium-term and individual lesson plans. Concludes that trainees' practice in science improved in subsequent unmentored lessons, but good practice was not transferred to other subjects.…

Presents a study to determine whether biology students in preservice training to become high school teachers hold correct scientific views that will eventually allow them to plan and implement instructional strategies which in turn will lead their future students to achieve a correct scientific concept of force. (Author/DKM)

Presents findings from a case study into the development of student understanding of chemical bonding. Reveals significant progression in student understanding but also highlights issues of how such progression should be addressed. Emphasizes factors associated with blocks to appropriate concept development. (33 references) (Author/MKR)

Presents a method for representing students' knowledge about basic scientific concepts by classifying ideas produced in a free-writing task. Implies that those differences which exist can best be attributed to general fluency in the language of instruction rather than factors that are specific to the learning of science. (Author/CW)

Investigates 5th and 6th grade students' learning when taught with the aid of dome and computer planetaria. Finds both planetaria equally effective with female pupils. Recommends the use of planetaria, which might enable females to catch up with males in areas that place heavy demands on spatial ability such as astronomy. (Contains 16 references.)…
