A project addressed the lack of rural school laboratory facilities and limited opportunities for staff development by training 22 high school physics teachers in rural Missouri to use videotaped "virtual" laboratory experiments and student data-collection worksheets. Surveys identified 19 topics for which physics teachers reported…

An American Institute of Physics survey was modified to determine major physics topics emphasized in small Missouri high schools and teachers' perceived adequacy to teach them. Data tables show the emphasis that 103 Missouri teachers placed on 38 physics topics, compared to national counterparts, as well as teachers' perceptions of their knowledge…

The purpose of this study was to determine which magnet concepts were found in various science textbook series, how the concepts were presented, and to identify potential misconceptions related to magnets. Magnet concepts presented as prose, illustration, and/or laboratory activities are identified and analyzed. (KR)

Examines elementary science methods textbooks to determine how magnet concepts are presented. Focuses on the organization, sequence of concepts, and potential misconceptions, and includes types of investigations. Analyzed 11 elementary science methods textbooks in detail and found great variation in the magnet concepts presented, general omission…
