Visual aids are important to student learning, and they help make the teacher's job easier. Keeping with the "TPT" theme of "The Art, Craft, and Science of Physics Teaching," the purpose of this article is to show how teachers, lacking equipment and funds, can construct a durable 3-D model reference frame and a model gravity…

A hands-on approach to introduce the chemical elements and the atomic structure to elementary/middle school students is described. The proposed classroom activity presents Bohr models of atoms using common and inexpensive materials, such as nested plastic balls, colored modeling clay, and small-sized pasta (or small plastic beads).

Discussion of visible models of training course organization covers uses for course designers, including clarifying course structure, planning lessons, communicating course requirements, and presenting a course overview; six steps to produce a visible model; and benefits for designers, instructors, and students. An example of a schematic diagram…

Having used the apperception-interception method (AIM) of adult basic education (ABE) successfully abroad, World Education, with Office of Education funding and working at several American sites, developed a model of innovative ABE methods and materials for the United States, based on addressing learners' motivational problems. By using…

While much visually oriented teaching material that uses the new technologies is being developed, there is little understanding or research into the demands such material makes on students' information processing. This paper outlines an innovative approach to teaching complex economic models that incorporates the convergence of text and graphics…
