This paper provides a commentary on research on models-based practice within physical education and presents a tutorial that aims to guide the reporting of future research using pedagogical models. Three key elements are presented that could be considered as essential for inclusion in any methods section in order for readers to gain an accurate…

This article describes an instructional program which starts with the student and then identifies three elements which operate interactively as a means to achieving desired ends. The three elements (educational objectives, learning experiences, and evaluation activities), when specified and cross-checked, yield a configuration indicating what the…

Presents a mechanical analog designed to reduce the conceptual difficulties experienced by many students in thinking about age distribution concepts in demography. (JR)

Analysis of first-grade reading instruction reveals that teaching contains important technological elements, which can be formulated as principles expressing coherent connections between means and ends; they pervade school-system organization and are not restricted to classes. Teaching is not largely intuitive, unpredictable, or resistant to…

Presents several models to describe the instructional approaches adopted by many teachers, and analyzes the roles of the teacher and students that seem to be implicit in each model. (JR)

Explores the applicability of Mulliken's united atom model to a variety of chemical systems and demonstrates its value as a teaching tool. Considers applications to first row hydrides, compounds of the first and second periods, heavy atoms, and cluster systems. (MVL)

Discusses the least squares technique and states the difficulty in finding suitable examples for using it in the chemical laboratory. Provides several least squares equations and the accompanying three dimensional drawings. Notes graphic lecture aids are available from the author as either slides or overheads. (MVL)
