Testing the ATI hypothesis: Should multimedia instruction accommodate verbalizer-visualizer cognitive style?

College students (Experiment 1) and non-college adults (Experiment 2) studied a computer-based 31-frame lesson on electronics that offered help-screens containing text (text group) or illustrations (pictorial group), and then took a learning test. Participants also took a battery of 14 cognitive measures related to the verbalizer-visualizer dimension including tests of cognitive style, learning preference, spatial ability, and general achievement. In Experiment 3, college students received either both kinds of help-screens or none. Verbalizers and visualizers did not differ on the learning test, and almost all of the verbalizer-visualizer measures failed to produce significant attribute x treatment interactions (ATIs). There was not strong support for the hypothesis that verbal learners and visual learners should be given different kinds of multimedia instruction.     

The effect of frequency of testing upon the measurement of achievement in an intensive time-series design

Progress in the development of an intensive time-series design for use in classroom situations has raised several questions regarding the validity of the data obtained. One such question is related to the effect of frequency of testing upon the data. This study was designed to determine the presence of such an effect. Use of the design with eighth grade students studying a unit on crustal evolution indicated that the frequency of data collection did not adversely affect student attitudes toward the science class nor did it have any measurable effect upon class achievement data. The results of a previous study were also replicated, giving increased confidence in the validity of the data yielded by the intensive time-series design as used in these studies.

Frequency norms and structural analysis of algebra story problems into families,categories, and templates

The goal of this study was to develop a framework for classifying algebra story problems and to determine observed frequencies for each problem type. A total of 1097 algebra story problems were selected from ten standard algebra textbooks. These are divided into eight families based on the nature of the source formula involved; for example, nearly 300 problems were classified in the time rate family because they were based on the source formula, distance = rate x time or output = rate x time. Each family was divided into problem categories based on the general form of the story line; for example, the time rate family consisted of motion, current, and work categories. Each category was divided into templates based on the specific propositional structure of the problem; for example, there were a dozen templates for motion problems such as overtake, closure, round trip, etc. This article describes the procedure for generating families, categories, and templates and provides frequency counts for each observed template. Implications for fostering productive research and instruction are discussed.This research was supported by grant NIE-G-78-0162 from the National Institute of Education.

面向意义学习的认知过程

学习不仅包括获取知识,还包括在各种各样的新情况下运用知识的能力,即学习包括“保持”和“迁移”这两个过程,本文以此观点为基础分析了意义学习与机械学习的区别,依据新修订的布卢姆认知目标分类学,对意义学习中的六类19种认知过程具体要素作出了说明,以此凸现认知过程中的“迁移”,帮助教育者更全面地完成教学和评估目标。     

What really matters in the early literacy development of deaf children

With much earlier identification of hearing loss come expectations that increasing numbers of deaf children will develop literacy abilities comparable to their hearing age peers. To date, despite claims in the literature for parallel development between hearing and deaf learners with respect to early literacy learning, it remains the case that many deaf children do not go on to develop age-appropriate reading and writing abilities. Using written language examples from both deaf and hearing children and drawing on the developmental models of E. Ferreiro (1990) and D. Olson (1994), the discussion focuses on the ways in which deaf children draw apart from hearing children in the third stage of early literacy development, in the critical move from emergent to conventional literacy. Reasons for, and the significance of, this deviation are explored, with an eye to proposing implications for pedagogy and research, as we reconsider what really matters in the early literacy development of deaf children.
