By having subjects drive a virtual taxicab through a computer-rendered town, we examined how landmark and layout information interact during spatial navigation. Subject-drivers searched for passengers, and then attempted to take the most efficient route to the requested destinations (one of several target stores). Experiment 1 demonstrated that…

The old adage that a picture is worth a thousand words also holds true in cell biology. Much of the knowledge that we have of the structures and functions of cells has been acquired by biologists peering through the eyepieces of microscopes. The point of this lesson is to provide an opportunity for students to observe cell biological data while…

Lecture recording provides learning material for local and distance education. The TeleTeachingTool uses the very flexible screen recording technique to capture virtually any material displayed during a presentation. With its built-in annotation system teachers can add freehand notes and emphasize important parts. Unlike other screen recorders,…

Lecture recordings can be a powerful addition to traditional lectures and they can even serve as a main content source in a number of didactic scenarios. If users can quickly locate relevant passages in a recording, the recording combines the ease of search that comes with electronic text based media with the authenticity and wealth of information…

Many children with autism have severe difficulty in "reporting" on events at schools to mothers at home despite their ability to tact some objects and actions in discrete trial setting. Many studies have attempted to establish tact as labeling in children with autism. Few studies, however, have attempted to establish tact as a functional…

Even though the appearance and spread of new technologies offer considerable challenges in the design of far reaching and complex pre-test and assessment situations which are in keeping with the trends of teaching and learning, the thematic map is still an insuperable document to value either integral training or academic performance of future…

Parents' object labels can be distinguished by whether the child is already attending to the object (follow-in) or not (lead-in). Lead-in labels have been found to be associated with low vocabulary. The current study examines whether the relation between lead-in labels and child vocabulary is influenced by whether the child's attention is…

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.
