Practical work in secondary-level chemistry laboratories involves a high cognitive load for students. In addition to reading and understanding instructions, students have to think about observations and the underlying chemical concepts, as well as deal with the noise and social interaction of a busy classroom. One form of extraneous cognitive load…

To address the needs of the high population of students with learning disabilities at their school, the author and a colleague created an inclusion science class that focuses on active, hands-on science. The course prepares students of various learning abilities for the state-mandated end-of-course biology assessment. Many of their students have…

In the lesson on which this practical article is based, third grade students constructed a "lift-the-flap" page to explore food webs on the prairie. The moveable papercraft focused student attention on prairie animals' external structures and how the inferred functions of those structures could support further inferences about the…

This paper presents a new course, Radionavigation Systems, whose laboratory and theoretical components complement each other to enhance student learning. Radionavigation skills and knowledge are taught by means of various instructional methods, and the laboratory successfully merges hands-on learning using specific instrumentation and software…

Visual intelligence is a key element in the thought processes of the most capable and creative among individuals, and this intelligence is closely related to analogical thinking, a learner's ability to make connections between prior knowledge and newly presented information. This article describes an approach to teaching scientific inquiry at…

For three biology professors, visualizing molecular processes is central to thinking in their discipline. This chapter reports their attempts at getting students to make this same cognitive move and the results of their assessments. (Contains 2 figures.)
