Recent reports have begun to lay the foundation for a re-visioned K-8 science curriculum which includes four strands that could be used to define and assess science proficiency for all students. Using these strands as an analytic lens, this pre-post multiple-case case study explores elementary school science teachers' practices and their students'…

Examines three anecdotal cases of the teaching of evolution theory in an exploration of the best approaches for teaching about evolution. Three instructional options are presented: (1) readings in natural history, (2) commercially prepared activities, and (3) the use of small-group (peer) discussions. (LZ)

Presents a narrative account of an activity designed to extend the understanding of both science curriculum and alternative assessment for prospective science teachers enrolled in an advanced undergraduate course. The activity models instructional practice in a methods class. (LZ)

Discusses the following questions: (1) What is hands-on science? (2) What does it mean to be engaged in hands-on science activities (HOSA)? (3) How can teachers tell good HOSA? (4) When is a good time to use HOSA? (5) What can students learn from HOSA? (6) What assessment techniques will help teachers understand what students are learning? (PR)
