How we should control time on task—or should we?

Typical experimental studies of learning aids will control in various ways for the time spent on the learning task. This paper reviews such methods and compares the possible confounding influences of indirect time effects in experiments with broad or restrictive time limits. Indirect time effects refer to changes in time spent on a text that are caused by learning aids. They are to be discerned from direct time effects that refer to the time the reading of the learning aids take. In particular, we give an overview of the adequacy of various time limits for answering different research questions. It is argued that experiments without time limits are potentially more likely to bring out performance effects. In the final part of this paper we give some illustrations of the different effects and methods, based on a series of six experiments into the influence of concrete analogies on learning. Those experiments show that indirect time effects are important and that performance results depend on the way one controls reading time.     

Adding a design perspective to study learning environments in higher professional education

How to design learning environments leading to learning-, thinking, collaboration- and regulation skills which can be applied to transferable, knowledge oriented learning outcomes is still controversial. We studied the designs of learning environments in innovative higher professional education more closely. To characterize learning environments we identify designable elements and position them on a scale ranging from specified, to emergent elements. Next, the main problems with the designs are identified. We introduce adaptive elements as a potential solution. We observed participants adapting such elements to suit their own needs or the needs of others. The designable and adaptive elements fulfill a dual function: they should offer contextual clues that would be available in professional practice and scaffold learners in need of support.     

Computer‐Assisted Instruction and Conceptual Change

Abstract

In this study, the question was addressed which instructional conditions are required to teach students how they themselves can initiate and perform learning activities aimed at conceptual change. The CONTACT‐2 strategy (a computer‐assisted instructional strategy for promoting conceptual change in the domain of basic physical geography) served as starting point for the design of several training procedures aimed at enhancing self‐regulated learning. With the first experimental condition, strategic support was gradually withdrawn ('faded') within each instructional step, while, with the second experimental condition, the number of steps was reduced as the training continued. The original CONTACT‐2 condition served as control condition. Subjects were 65 fifth‐ and sixth‐graders (primary education). Dependent variables concerned students’ abilities to initiate and perform learning activities aimed at conceptual change, the quality of their conceptions, and their learning performance. Results suggested that ‘fading’ can be a fruitful instructional approach to foster self‐regulated learning aimed at conceptual change, provided that the ‘fading’ procedure is tuned to the students’ actual level of self‐regulated learning: external control should not be withdrawn until students are able (and prepared) to initiate and perform the learning activities being required. When these conditions are met, designing effective training procedures aimed at ‘learning for conceptual change’ seems possible.     

Test of gross motor development-2 for Filipino children with intellectual disability: validity and reliability

This study aimed to examine aspects of validity and reliability of the Test of Gross Motor Development-2 (TGMD-2) in Filipino children with intellectual disability. Content and construct validity were verified, as well as inter-rater and intra-rater reliability. Two paediatric physiotherapists tested 81 children with intellectual disability (mean age = 9.29 ± 2.71 years) on locomotor and object control skills. Analysis of covariance, confirmatory factor analysis and analysis of variance were used to test validity, while Cronbach’s alpha, intra-class correlation coefficients (ICC) and Bland–Altman plots were used to examine reliability. Age was a significant predictor of locomotor and object control scores (P = 0.004). The data fit the hypothesised two-factor model with fit indices as follows: χ² = 33.525, DF = 34, P = 0.491, χ²/DF = 0.986. As hypothesised, gender was a significant predictor for object control skills (P = 0.038). Participants’ mean scores were significantly below mastery (locomotor, P < 0.001; object control, P < 0.001). Cronbach’s alpha was 0.830 for locomotor and 0.792 for object control components. ICC for locomotor and object control scores ranged from 0.995 to 0.998, suggesting excellent intra-rater and inter-rater reliability, confirmed by Bland–Altman analysis. This study provides evidence of sufficient content and construct validity, internal consistency and rater reliability of TGMD-2 for Filipino children with intellectual disability.     

Effects of network treatments on perceptions of a political campaign film: Can rhetorical criticism make a difference?

Presented here are the findings from a quasi‐experimental comparison of three network treatments of “A New Beginning,” a campaign film that aroused considerable controversy when the Republicans substituted it for a speech at the 1984 Republican National Convention as a way of getting the networks to air it. Of paramount interest in the study were the effects on viewers of one network's critical preview of the film. Of the three major networks, only NBC elected to air the entire film, but they preceded its showing with a commentary on the film that was far more critical than those by CBS and ABC. Surprisingly, Ss predisposed toward Ronald Reagan did not derogate the NBC treatment of the film, but neither did NBC's criticisms adversely affect perceptions of the film. To the contrary, ratings of the film and network treatments of the film were highest for NBC viewers. The findings are discussed with a view toward assessing the uses and limitations of rhetorical criticism in television coverage of political campaigns.     

Librarians,Faculty, and the Writing Center Partnering to Build an Interdisciplinary Course: A Case Study at the University of Houston,USA

This article covers how an interdisciplinary course was developed using the expertise and resources of a history professor, the history and psychology subject librarians, and the university's writing center. The course, supported by a grant, was aimed at helping students improve their research, information literacy, and writing skills across disciplines. The article discusses the involvement of the partners from the initial planning stages to its conclusion, focusing especially on how the librarians created a library session, course-specific guide, annotated bibliography assignment and grading rubric, and how these were used as opportunities to interact with the students throughout the course. Also covered are research and writing challenges, especially for English-language learner students, and how they were addressed by all the partners. It also discusses how the librarians used this experience to seek out opportunities to create similar collaborations with other instructors, and to strengthen ties with support services on campus.
