Nearly 100 teachers worked with staff members at the Exploratorium museum in San Francisco, California, to create scaled-down versions of Exploratorium exhibits that teachers could make on their own using common, inexpensive, readily-available materials. The experiments--called "snacks"--are divided into easy-to-follow sections that…

Developed by classroom teachers during the development phase of Minnesota's Graduation Standards, this performance package is made up of locally designed assignments that, taken together, show whether a student has learned and can apply the knowledge and skills related to comprehending technical information from documents or electronic media and…

The emphasis on laboratory activities for science students has increased. This paper describes research that sought to determine which laboratory skills and competencies are viewed by current teachers as necessary for the preservice teacher to develop. The skills and competencies survey included 145 items in three categories (general, biological…

"How Students Learn: Science in the Classroom" builds on the discoveries detailed in the best-selling "How People Learn." Now these findings are presented in a way that teachers can use immediately, to revitalize their work in the classroom for even greater effectiveness. Organized for utility, the book explores how the principles of learning can…
