Prior research has established that teachers' use of curriculum materials is affected by a range of factors, such as teachers' conceptions of mathematics teaching, and the nature and extent of their teaching experience. What is less clear, and far less examined, in prior research is the role that the teacher guide (TG) may play in mediating the…

This paper defines correlation, describes the Mix It Up program, discusses the teachers' beliefs about the value of correlating mathematics and science prior to program participation, and identifies problems teachers associated with correlation before and during the program. Teachers' beliefs about the value of correlation and about the problems…

An overview is provided of 50 years of research on naive theories in human biology. A set of recommendations aimed at confronting student misconceptions and facilitating conceptual change about the structure and function of the human body is presented, with five lessons described. (MNS)

A handbook for teachers of calculus and analytic geometry is described. Five categories of materials are included, with illustrative examples and a lesson plan. (MNS)

Presents five integrated mathematics and science lessons in which students investigate the characteristics, behavior, lifecycles, and motion of mealworms and the feasibility of raising mealworms for profit. Purpose, time, materials needed, procedures, and extensions for each activity are provided. (MDH)

Presents a historical and content background of the metric system. Describes 1 of a series of integrated hands-on lessons for grades 4-7 to teach the measuring of volume with metrics. Provides a worksheet for the lesson and a concept map of the metric system. (MDH)

Presents activities to supplement lessons on length and mass measurement or as part of a unit on atoms or orders of magnitude. Provides a lesson plan using aluminum foil to estimate unit measures, calculate the foil's thickness, and do an atom count. (MDH)

Describes a teaching experiment that evaluated published supplemental materials used to aid preparation of lessons at the fourth grade level involving nonroutine word problems. Lists 12 insights gained that can be useful to teachers using commercially produced problem-solving materials. (MDH)
