关于高等数学教学的几点思考

随着素质教育的推进与高等教育走向大众化,高等数学这门基础课程的教学工作面临了巨大的压力。为保证教学质量更好的完成教学工作,笔者提出了关于认清课程开设意义、树立统一合理的教学理念,从学生心理特点出发开展有效教学和立足长远注重课程建设与完善三方面的想法并给出了详细的分析。     

Light's retention scale: Does it have content validity?

The content validity of the Light's Retention Scale (LRS) was examined by assessing the use of selected retention criteria from the scale. Results indicated that several criteria were not typically considered in retention decisions and the remaining criteria varied widely in their use. Suggestions for limitations on use of the LRS were included.     

Relationships between age and raw score increases on the Kaufman-assessment battery for children

Raw scores on the 16 K-ABC subtests and the total raw scores on the sequential and simultaneous processing scales and the achievement scale were correlated with age in months for two separate samples, each subdivided by race and sex: the K-ABC standardization sample (N = 2000) and an additional group of blacks and whites tested during the development of the K-ABC sociocultural norms (N = 615). Within each sample, the highest and lowest correlations from all race/sex groups were contrasted across all K-ABC subtests and scales. All correlations between age and raw scores were statistically significant (p ⩽ .05). No significant differences occurred in the magnitude of these relationships as a function of race/sex grouping, supporting the construct validity of the K-ABC as a developmental measure of children's aptitude and achievement for blacks, whites, Hispanics, males, and females.     

Reflections on “teaching discrete skills to students with moderate mental retardation in small‐group instructional arrangements”

Several response‐prompting strategies exist for teaching students with disabilities (Wolery, Ault, & Doyle, 1992). With these strategies, prompts are provided to ensure that students perform the target behaviors in the presence of the target stimuli. However, to transfer stimulus control from the prompts to the target stimuli (i.e., to establish independent and appropriate responding), the prompts must be faded. Often, the various strategies differ on the manner in which prompts are faded.     

Audio-Visual Training in the Netherlands

In 1972 the Netherlands Institute for Audio-Visual Media (NIAM) in the Hague established a new department in Rotterdam to provide information and advice on the selection of audiovisual equipment and training in the use and applications of the different media. The information service was to be provided free of charge, but a fee would be charge for the training courses.
