Video Presentations that have to Teach

To be successful, an instructional video presentation needs to be effective, valued, liked and efficient, and educationalists and designers should strive (explicitly and implicitly) to satisfy these criteria. In the interests of optimum teaching effect, a didactical distinction is recommended between video presentations that have to ‘instruct’, ‘explain’, ‘tell’ and ‘let encounter’. A schema or frame of reference is proposed, the use of which (it is claimed) can help to optimise communication between video producer, teacher and instructional designer     

Concurrent validity of the test of nonverbal intelligence with learning disabled children

Results of the TONI, WISC-R, and WRAT were compared for a sample of 66 learning disabled children: 51 males (32 white, 19 black) and 15 females (9 white, 6 black) whose mean age was 9–5 (SD = 1–10). The mean score of the TONI was significantly different from the Performance IQ. Nonsignificant differences were found between the TONI and Full Scale IQ and between the TONI and Verbal IQ. Correlation coefficients between the TONI and WISC-R ranged from a low of .35 for the Verbal IQ to .44 for both the Full Scale and Performance IQs. The correlation coefficients between the TONI and standard scores of the WRAT were .38, .27, and .23, for Reading, Spelling, and Arithmetic, respectively. Implications of these findings are discussed.     

Are mastery learning strategies beneficial for developing problem solving skills?

The purpose of the present study was to investigate instructional methods appropriate for developing problem solving skills (PSS) in a paramedical course. Three instructional methods were compared: Frontal Lecture Strategies (FLS), Mastery Learning Strategies (MLS) and Experiential Mastery Learning Strategies (EMLS) in which feedback corrective procedures were embedded within experiential learning situations. Results showed that FLS produced the highest scores on Lower Mental Process subtest while EMLS yielded the highest scores on all measures of problem solving skills. Several implications of this study for future research are suggested and discussed.     

Evidence for confounding in computer-based instruction studies: Analyzing the meta-analyses

A thirty percent sample of the computer-based instruction (CBI) studies meta-analyzed by Kulik et al was examined for evidence of confounding. The purpose of the analysis was to explore the validity of competing claims about the contribution of the computer to measured achievement gains found in CBI studies. Some of these claims propose that CBI effects are overestimated and others argue that CBI effects are underestimated. The result of the analysis strongly suggests that achievement gains found in these CBI studies are overestimated and are actually due to the uncontrolled but robust instructional methods embedded in CBI treatments. It is argued that these methods may be delivered by other media with achievement gains comparable to those reported for computers. Construct validity cautions are offered for those who wish to use meta-analytic results as evidence for implementing CBI in schools and for the design of future CBI research.     

School Effects in Scottish Secondary Schools

The present paper examines whether there is significant variation in schooling outcomes between Scottish secondary schools, and if so, how much is associated with pupil intake, and how much is associated with the schools they attend. It also examines whether schools vary in their effectiveness for different types of pupils, and whether schools tend to be superior, or inferior, across three different outcome measures. The study employed a subsample of data from the 1977 Scottish School Leavers Survey on over 700 pupils from 15 schools in one administrative division. These data were linked to data on the verbal reasoning quotients of the pupils, derived from a test administered to them before they entered secondary school. For each of the 15 schools we estimated the expected scores on measures of English, arithmetic and overall attainment for pupils with below average, average, and above average ability, controlling for pupils’ verbal ability, gender, prestige of father's occupation, mother's education, and number of siblings. The study shows there was wide variation in schooling outcomes between secondary schools in the division, even after controlling for family background characteristics and pupil ability prior to entering secondary school. There were few schools that were particularly effective for low ability pupils, but not high ability pupils and vice versa. Schools tended to be effective, or ineffective, across all three outcome measures.     

Experiential Learning and Management Education

Two core subjects in operations and strategic management have been developed for the final year of a Bachelor of Business (Management) degree. The subjects are interrelated and emphasise experiential learning. Objectives of the subjects are presented, and the reasons for their experiential emphasis given. Experiential exercises for some topics are briefly described, together with an assessment of their worth and the reasons for their development. The exercises include a work study of leggo block construction, role plays, environmental scanning, industrial negotiations, and a business simulation that threads through both subjects.     

Prediction of the science inquiry skill of seventeen-year-olds: A test of the model of educational productivity

The study was designed to investigate the influence of student characteristics and classroom characteristics on students' inquiry skill. The sample consisted of a national stratified random sample of 1955 17-year-olds who were assessed as part of the 1981-1982 national assessment in science. The dependent variable was a 17-item measure of students' inquiry skill. The independent variables were selected from the available data using the Model of Educational Productivity as a guide in the selection of the variables. The first purpose of the study was to test the effectiveness of the Model of Educational Productivity for predicting the inquiry skill of 17-year-olds. The results of this study indicate that this model was capable of accounting for between 24 and 32% of the variance in inquiry skill for the general population of 17-year-olds. More specifically, students' reporting of their general ability alone accounted for between 17 and 22% of the variance. The second question posed by this study asked whether the prediction of inquiry skill differed for males and females. While there was some difference in the contribution of the minor predictors, there was very little difference in the prediction of inquiry skill for males and females using the Model of Education Productivity. The third question posed by this study asked whether the prediction of inquiry skill differed for white and nonwhite students. For nonwhite students, the Model of Educational Productivity accounted for only 18% of the variance in science inquiry skill. Thus, it would appear that there is a great deal that is not known about the factors that contribute to the science inquiry skill of nonwhite students.     

Comparing preservice,elementary, and junior high teachers' perceptions of school psychologists: Two decades later

One hundred eighty-one experienced teachers (elementary and junior high), and 189 preservice teachers were surveyed regarding their perceptions of school psychologists. The survey instrument used essentially the same categories as Styles in 1965, including: (a) level of training, (b) effectiveness, (c) qualifications for tasks, and (d) usefulness in specific duties. Analysis of the survey data showed there were significant differences between preservice and experienced teachers' effectiveness ratings of school psychologists on eight tasks typically performed by school psychologists. Significant differences also were found between preservice and experienced teachers on their ratings of school psychologists' qualifications to undertake specific tasks, although almost half of the experienced teachers were unable to rate the effectiveness of school psychologists. There was a small, but significant, negative relationship between the amount of contact with the school psychologist and the perceived effectiveness. Limitations inherent in survey methodology and the need to foster greater teacher awareness of the school psychologist's role are discussed.
