A dynamic measure (number of examples needed to reach mastery) predicted transfer but not maintenance of a learned strategy for 64 third graders trained by scaffolded (n=32) or nonscaffolded (n=32) methods. A static measure had some predictive utility in the nonscaffolded condition. The potential superiority of scaffolded instruction is discussed.…

A non-informative cue (C) elicits an inhibition of manual reaction time (MRT) to a visual target (T). We report an experiment to examine if the spatial distribution of this inhibitory effect follows Polar or Cartesian coordinate systems. C appeared at one out of 8 isoeccentric (7[degrees]) positions, the C-T angular distances (in polar…

We describe a case study of an in-service professional development project with four experienced biology teachers in two upper secondary schools. The objective was to better understand the role of laboratory work (labwork) in science education with a special emphasis on assessment. Research questions include the following: 1. What does the teacher…

As science and technology develop, the use's areas of Fuzzy Logic Theory develop too. Measurement and evaluation in education is one of these areas. The purpose of this research is to explain the influence of fuzzy logic theory on students' achievement. An experimental method is employed in the research. The traditional achievement marks and The…

In this study an attitude questionnaire was developed and applied to identify student teachers' interests and attitudes for basic physics laboratory. In physics laboratory practices run by a higher education institution a new attitude questionnaire was developed and applied twice in two terms by researchers to increase student teachers' success…

The target of difficulty of the Educational Technology Center (ETC) Heat and Temperature Group is basic thermal physics, particularly the differentiation between heat and temperature. High school teachers often find that thermal concepts are very difficult for their students to master and attribute students' difficulties at least in part to the…

Students from science, engineering, and technology programs should be able to work together as members of project teams to find solutions to technical problems. The exercise in this paper describes the methods actually used by a project team from a Biomedical Instrumentation Corporation in which scientists, technicians, and engineers from various…

An "undesigned" experiment is one in which the predictor variables are correlated, either due to a failure to complete a design or because the investigator was unable to select or control relevant experimental conditions. The traditional method of analyzing this class of experiment--multiple regression analysis based on a least squares…

The concept of experiential education, defined as learning outside the normal classroom environment that has been planned for prior to the experience, is reviewed. This includes internships, field experience, practicums, and cooperative education. Topics covered deal with the liberal arts, professional training, institutional reform and the…

The voucher plan--a proposal to give parents the right and the financial means in the form of a voucher to send their child to the public, private, or parochial school of their choice--was developed as a "model" and, necessarily, without great sensitivity to differences among local school districts. The San Francisco Unified School…

In February 1971, the Seattle School District received funds to conduct a study of the feasibility of implementing the education voucher plan in Seattle. The study was divided into two preliminary phases. Phase 1 conducted over a 4-month period, consisted of an investigation of the areas of the city where the plan could best be tested, an analysis…

A study was made: (1) to determine whether children allowed to choose the difficulty levels of their arithmetic problems in a Computer Assisted Instruction (CAI) task would show greater engagement in learning than children who were not given a choice, (2) to discover possible patterns in the choices made, and (3) to determine the relationship of…

Using Fiedler's Contingency Model of Leadership Effectiveness, which postulates that the behavior of a leader depends on the interaction between leadership style and the degree to which the environment gives the leader control and influence, a study investigated the effects of training and changes in position power on the behavior of three types…

Reports on a study that examined and compared the cognitive effectiveness of a traditional hands-on laboratory exercise with a computer-simulated program on the same topic. Sought to determine if coupling these formats would provide optimum student comprehension. Suggests hands-on exercises be followed by computer simulations as postlaboratory…

The emphasis on laboratory activities for science students has increased. This paper describes research that sought to determine which laboratory skills and competencies are viewed by current teachers as necessary for the preservice teacher to develop. The skills and competencies survey included 145 items in three categories (general, biological…
