This paper introduces various visual models for the analysis and description of learning processes. The models analyse learning on two levels: the dynamic level (as a process over time) and the functional level. Two types of model for dynamic modelling are proposed: the session trace, which documents a specific learner in a particular learning…

Wallsheets are used by teachers to instruct or to stimulate the class, are studied by the pupils under the teacher's guidance, or are used by the learners on their own in association with some sort of study guide. This booklet offers a close examination of ways of organizing learning opportunities so that the potential of wallsheets can be…

A study comparing the presentation of a completed diagram vs. one that is shown in successive stages produced no differences in recall, but students preferred the build-up method. (Author)

Techniques and advantages of using the flannel board as a communication device. Procedures are described for constructing visuals for flannel board manipulation from high contrast film. (STS)

The use of props in the early lessons of bookkeeping classes will help develop the analysis skills students need to know the "why" as well as the "how" of fundamental accounting principles. (Author/JOW)

In many ways, the role of visualization in science is distinct from other disciplines. Many natural processes--and even some objects--are too small, too fast, too slow, or too far away to view without highly specialized equipment. Of course, students at every grade level can understand a phenomenon better when they can see it. That is why…

In practice, videomaking in the classroom takes dedication, inspiration, and plenty of extra time. Despite these difficulties, teachers have always made great videos. Perhaps this is due to a combination of the tremendous appeal of video, the deep satisfaction of seeing stellar projects on the television set, and the knowledge that work can be…

The coordinates of an n-dimensional regular simplex are found. These coordinates are used to derive properties of the regular simplex that generalize their two- and three-dimensional counterparts.

An account of the impetus given by the Brynmor Jones report ("Audio visual aids in Higher Education", 1965) to the development of educational technology in Britain. The author, who was closely involved in the developments, discusses the influence of the audio-visual movement in the United States and the emergence of a national…

Introduction: This paper extends a series on summaries of Web objects, in this case, the alt attribute of image files. Method: Data were logged from 1894 pages from Yahoo!'s random page service and 4703 pages from the Google directory; an img tag was extracted randomly from each where present; its alt attribute, if any, was recorded; and the…

The equations for the liquid and gas lines in the binary temperature-composition phase diagram are derived by approximating that delta(H)[subscript vap] of the two liquids are equal. It is shown that within this approximation, the resulting equations are not too difficult to present in an undergraduate physical chemistry lecture.

This study explores the use of a mapping technique to test the invariance of proficiency standards over time for state performance tests. First, the state proficiency standards are mapped onto the National Assessment of Educational Progress (NAEP) scale. Then, rather than looking at whether there is a deviation in proficiency standards directly,…

Our main goal in this study was to explore whether the use of models in high school molecular genetics instruction can contribute to students' understanding of concepts and processes in genetics. Three hundred and nineteen students from four comparable groups of 11th- and 12th-grade students participated. The control group (116 students) was…

Two-time Caldecott Honor winner (Free Fall, Sector 7) and three-time Caldecott Medal winner (Tuesday, The Three Pigs, Flotsam), David Wiesner is regarded as one of the most remarkable creators of visual storytelling living today. Wiesner is well known for his innovative and unique subject matter and his sophisticated painting-like illustrations…
