The purpose of this paper is to compare the effects of paper-based and computer-based concept mappings on computer hardware achievement, computer anxiety and computer attitude of the eight grade secondary school students. The students were randomly allocated to three groups and were given instruction on computer hardware. The teaching methods used for each group were the conventional method, paper-based concept mapping and computerbased concept mapping. At the end of a 4-week instruction, posttests were administered to assess computer hardware achievement, computer anxiety and computer attitude of the students. The findings indicate that paper-based and computer-based concept mapping strategies produce better results than the conventional method. However, the effects of paper-based and computerbased concept mapping strategies were not significantly different.
The purpose of the study reported on in this paper was to identify performance criteria and ratings in rubrics designed for the evaluation of learning in online asynchronous discussions (OADs) in post-secondary contexts. We analysed rubrics collected from Internet sources. Using purposive sampling, we reached saturation with the selection of 50 rubrics. Using keyword analysis and subsequent grouping of keywords into categories, we identified 153 performance criteria in 19 categories and 831 ratings in 40 categories. We subsequently identified four core categories as follows: cognitive (44.0%), mechanical (19.0%), procedural/managerial (18.29%) and interactive (17.17%). Another 1.52% of ratings and performance criteria were labelled vague and not assigned to any core category.
This study investigates effects of multimedia on cognitive load, self-efficacy and learners’ ability to solve multiple rule-based problems. Two hundred twentytwo college students were randomly assigned to interactive and noninteractive multimedia groups. Based on Engelkamp’s multimodal theory, the present study investigates the role of multimedia in multiple rule-based problem solving. The findings indicate that providing learners with manipulative function in multimedia would facilitate their problem solving through reduced cognitive load and improved self-efficacy. The study identifies a significant mediator effect for self-efficacy that mediates between multimedia and learners’ problem solving. Discussion focuses on the effects of multimedia and self-efficacy on learners’ performance in multiple rule-based problem solving. Suggestions are made with regard to the design of problem solving in future studies.
At the recent Wiley-Blackwell executive seminar for journal editors, there was much discussion of the relative merits of subscription publishing versus author paid publishing. For those who are not familiar with these two approaches, let me set out a very simplified description.
