Diagrams and explains construction of an actograph which quantitatively records daily movements of animals for a 24-hour period. Combines use of a kymograph and the teetering box of Palmer. Biorhythm activities with fiddler crabs, cockroaches, and hamsters are suggested. (CS)

A mathematics laboratory approach used with hearing-impaired junior high youngsters is described and discussed. (DT)

Preliminary evaluations of the University of Florida's pharmacy practicum-internship program cover: (1) the interns' subjective evaluations of their experiences; (2) the preceptor's subjective evaluation of interns' performance over two years; and (3) objective measurements of student competencies. (LBH)

Reports on a Listen-Read Program exposing children to a variety of language in sound and print through the coordinated use of books and listening centers; a study of the program indicated higher scores on a standardized reading test resulted from children's listening to the text while they read. (HOD)

Listening comprehension exercises in second language instruction are expected to: (1) increase students' efficiency at message extraction, and (2) lead to assimilation of new vocabulary and expressions. Data from a small experiment using such exercises illustrate the distinctions drawn and the limitations. (CHK)

Presents short articles on: display of line spectra, calorimeters, filling balloons from gas jets, and digital mini-module systems. (MLH)

Directions are given for an activity in which students are introduced to infinite geometric series. (DT)

After summarizing the findings of laboratory experimental geropsychological research pertinent to the instruction of older adults, this review focused on delineating the explicit implications of the research for adult education. Thirty-six implications were culled from the literature and categorized under 10 instructional variables. (Author/LAS)

Examines student and teacher perceptions about the purpose and effectiveness of laboratory work at Year 10. The views of students and their teacher on the goals, conduct, and assessment of laboratory work were compared. Findings suggest that the relevance of laboratory work to everyday life could be made clearer to students. This may entail…

A study of 144 patients assigned to eight orthodontic residents over two years found residents requested lateral tomograms of the temporomandibular joint (TMJ) 28% of the time, commonly citing TMJ clicking, pain, and medico-legal protection. Posteroanterior cephalograms were ordered 26% of the time, commonly for facial asymmetry and maxillary…

Presents a laboratory in which students are provided with cultures of three bacterial strains. Using the results, students will determine which of the strains corresponds to a mutant lacking a particular functional gene. (DDR)

Describes a high school chemistry class that regularly studies a local river to incorporate hands-on environmental studies into chemistry topics. This integration has proven to be a successful technique to make science come alive for students, arouse students' curiosity, and convince students that chemistry is indeed everywhere. (DKM)

Presents an activity that focuses on insects and the choices they make in response to sensory input. Involves students and teachers in inquiry-oriented investigations and presents details of preparation, a discussion of the teacher's role, and a materials list. (DDR)

Presents an exercise to demonstrate two fundamental concepts of fluid mechanics: the Reynolds number and the Principle of Continuity. The exercise demonstrates flow in a major blood vessel, such as the aorta, with and without a stenosis. Students observe the transition from laminar to turbulent flow as well as downstream persistence of turbulence.…

Access to professional development opportunities for in-service high school chemistry teachers remains a problem. In an effort to increase teacher access, a new cross-listed course called Chemistry 869/Curriculum and Instruction 869 was created at the University of Nebraska and offered via the Internet. Describes this course in microscale…
