Discusses strategies to make life science classes more fun by planning activities that include preserved and live specimens. Discusses field trips and collections. (JRH)

Proposes that chemistry, biochemistry, physics, and arithmetic form a base from which students can focus on consumer issues. Describes a hands-on science program that stresses real world topics and employs portfolios which consist of a term paper, a student designed experiment, lab reports, and tests. (DDR)

Asserts that traditional teaching methods are unintentionally biased towards the elite and against many non-traditional students. Outlines several easily accessible changes in teaching methods that have fostered dramatic changes in student performance with no change in standards. These approaches have proven effective even in the fields of…

Researchers at the University of Utrecht (Netherlands) examined preservice physics teachers' motives for attending an orientation course, noting how the motives developed and changed. Periodic surveys indicated that students had five motives, the most important being desire to learn whether they wanted to be secondary teachers (followed by…

An experimental lesson is described in which student teachers verbalized preconceptions about a natural object (mushrooms) and completed personal response activities about a poem entitled "Mushrooms." The approach stimulated enhanced awareness of mushrooms and more questions about growth and reproduction. Possible applications in…

Examines the scientific concept of evaporation. Attempts to show how students develop their understanding through the levels of the Structure of the Observed Learning Outcome (SOLO) taxonomy. Shows how designing learning experiences to suit the learners' developmental stages in understanding a concept is paramount to the overall growth of the…

Investigates the knowledge of elementary school teacher candidates on rock-cycle processes. Three different instructional interventions were used to improve their knowledge: (1) conceptual-change teaching; (2) traditional didactic teaching; and (3) microteaching. The conceptual-change group showed the most growth in understanding, supporting…

Examines some of the misconceptions about the nature of critical thinking. Focuses on the characterization of critical thinking in terms of processes or skills and the separation of critical thinking and knowledge. Offers a different conception of critical thinking. (Contains 46 references.) (DDR)

This article describes an inquiry-based science project, presents the professional development that supported it, gives recommendations to teachers of inclusive classrooms, and provides a practical checklist for program assessment. A list of teacher characteristics recommended for the inquiry approach is also provided, along with classroom design…

This article discusses how Magnetic Levitation (Maglev) can be taught to gifted students in grades 4-9 using hands-on activities that align to the National Science Standards. Principles of magnetic levitation, advantages of magnetic levitation, construction of a Maglev project, testing and evaluation of vehicles, and presentation of the unit are…

Presents an online trivia game on laboratory safety. (YDS)

Reviews the history of and describes what biology educators should know about the topic of bioterrorism. Suggests materials that can be used to communicate more effectively with students and the community and prepare a classroom discussion on bioterrorism. (KHR)

Presents a 10-week unit on rocks and minerals for 2nd and 3rd grade classes of students with disabilities. Focuses on children's science process skills. Includes a sample worksheet. (KHR)

Improvements in the mechanism of the whirlybird used in the Science Curriculum Improvement Study (SCIS) unit "Subsystems and Variables" are presented. Variables which can be investigated using this device are discussed. An illustration of the improved device is provided. (CW)
