To investigate the affective and cognitive gains produced in an auto-tutorial world civilizations course, two groups of students were compared. A traditionally-taught (TT) section of 145 students and an auto-tutorially (AT) taught section of 140 were given pre- and posttests and used the same text and Modular Learning Program. The TT section…

Seven mastery instruction courses offered in different quarters at the University of Washington are examined. The study method involved obtaining student ratings of these courses for comparison among themselves and with student ratings of traditional lecture method courses in the same subject field. For this purpose a Mastery Instruction Student…

An integrated learning strategy program emphasizing a connection technique employing questions and answers was developed and tested. Components were derived from a review of educational and psychological literature and from an analysis of responses to a learning-strategy inventory. Visual imagery and paraphrasing connection also were evaluated.…

A computer-assisted simulation of experiments in eyelid conditioning was conducted as part of an introductory psychology course. This instructional format was then compared with a traditional instructor-led seminar and with a seminar in which computer-produced information obtained elswhere was used. A total of 120 students participated in 11…

The results of a number of experiments with the memorizing of several different subject-matters are presented in such a way that the relationship between number of opportunities for error (word elements faded) and number of errors actually made can be observed for individuals and groups. The particular selection of word elements to be taught by…

Designed to determine the feasibility of remote supervision of college students during their preservice teaching experience, this study focused on the use of three techniques of college supervision--face-to-face, audio-phone, video-phone--to ascertain their effects on student teacher improvement in specific teaching skills and in teaching…

A computer-assisted instruction (CAI) physics lesson on magnetism was supplemented with slides and film loops to provide a simulated encounter with simple magnetism experiments. Two groups of students took the CAI lesson, but one group viewed the simulated experiments, while the other group performed the actual laboratory experiments. Since…

An experimental course in college-level, introductory German, based on a modification of Fred S. Keller's work in individualized instruction, is described in this study. The establishment of specific time limits for completion of predetermined subject matter and the provision of tutorial services are essential variations from the classical…

This evaluation of two programs of materials used in introductory French classes tests two basic hypotheses: (1) pretests are good predictors of subsequent French achievement at the junior high school level, and (2) students in different programs will achieve to the same degree on a final French test. Results of the groups using the "audiolingual"…

This study explores the effect of visual stimuli on second language vocabulary development. An experiment performed at Georgetown University postulates the hypothesis that concrete target words learned through translation and visual aids should offer better learning than the same words learned through translation alone. Findings are determined…

Describes a simple thermodynamics experiment recommended for use in beginning chemical engineering laboratory courses. Outlines the theory behind the experiment, which determines the specific heat of a liquid. Discusses the construction, operation, and maintenance of the apparatus involved, along with the experimental procedure. (TW)

Describes efforts in devising a method for determining sulfate quickly and accurately from rainwater samples. Explains the design and operation of the apparatus and identifies the solutions for the testing. (ML)

Presents as part I of a two-part series a study involving the intercellular transfer of bacterial DNA that codes for the resistance to antibiotics. Demonstrates to students that such transfers occur. Discusses laboratory procedures, materials and results. (CW)

Presents the organization of a one-semester graduate course in structural chemistry including lectures and problems. Discusses the coverage of diffraction from real crystals and structure determination. Summarizes experiments on real crystals conducted by students in the X-ray laboratory. (CW)

Describes a simulation of the results of real experiments which use different strains of Escherichia coli. Provides an inexpensive practical problem-solving exercise to aid the teaching and understanding of the Jacob and Monod model of gene regulation. (Author/CW)
