Three generations of learning 普通类
The purpose of the present paperwas to examine three generations of research on technology-mediated learning carried on by the present investigator’s research group. The first generation focused on examining computersupported collaborative learning from the cognitive perspective. The main focus was to examine to what extent knowledge-seeking inquiry elicited conceptual change. Problems of transferring inquiry learning culture from one country to another pushed us to examine social practices and other participatory aspects of learning that had been invisible to cognitive researchers. The second-generation research focused on analyzing patterns of participation in computer-supported collaborative learning. The emerging third generation research aims at overcoming the dichotomy between the cognitive (knowledge acquisition) perspective and socio-cultural (participation) perspective by means of long-standing and deliberate efforts of knowledge-creation, involving what is called objects of activity. Theoretical and methodological implications of the generations are discussed.

Training teachers to use new technologies impacts 普通类
A pair of papers re-examined the evidence from a national initiative to train all teachers in England to bring them up to the level of newly qualified teachers, who are required to know when to use and when not to use information and communication technologies (ICT) in their professional practice. The first paper confirmed that multilevel evaluation of professional development was robust for ICT teacher training. This second paper contrasts the highest and lowest rated designs for ICT teacher training: an ‘organic’ approach that provided training in schools was highly rated, whereas a centralised computerassisted learning approach with online access to trainers was the lowest rated design. The study supports an ecological view of the diffusion of ICT innovations in education and recommends that ICT teacher training be designed to support evolution of each teacher’s classroom, school and region, as well as the training of the ICT teacher trainers.

The impact of the use of response pad system on 普通类
Although a number of researchers have examined response pad systems (RPSs) in higher education, there has been very little research at the K-12 level. This paper investigated the impact of using an RPS in the learning of physics concepts in a secondary school in Singapore. Two classes (n = 35 students in each class) of secondary five students participated in this study. One of the classes used an RPS while the other did not. Both classes completed a pretest and a posttest which tested the students in the application of the physics concepts taught. Results suggested that the class that used an RPS performed better in the posttest compared to the class that did not use the system. In addition,we explored the teacher and students’ perceptions of using the RPS.

I’ve stuck to the path I’m afraid 普通类
This paper draws on qualitative data from a study of student use of blended learning as part of a conventionally taught undergraduate Sociology course. Findings from an early evaluation questionnaire highlighted an overwhelming pattern of non-use of the materials and subsequent research with a group of 16 students evidenced limited and inconsistent engagement with the resources. In an analysis of the category ‘non-use’, the students’ rejection of the materials is seen to be closely related to a trust in traditional texts as authentic academic knowledge and an instrumental and strategic approach to study. Blended learning resources are shown to challenge existing learning patterns and practices, reconfigure existing understandings and expectations of academic scholarship and reconstruct academic boundaries in new spaces.

aper-based and computer-based concept mappings 普通类
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.

Rubrics for designing and evaluating 普通类
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.

Effects of multimedia on cognitive load 普通类
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.

Editorial Who pays for publishing 普通类
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.

An experience of teaching 普通类
In order to facilitate senior primary school students in Hong Kong to engage in learning by observation of the phenomena related to electrical circuits, a design of a specific courseware system, of which the interactive human–machine interface was created with the use of an open-source software called the LabVNC, for conducting online remote-controlled experiments was developed in this study. The statistically significant results of a pre-test–post-test evaluation study showed that the LabVNC-based system has potential to promote students to learn the target topic under the approach of learning by observation. The assertion of the teacher on the pedagogical value of the remote-controlled experimentation and the enthusiasm of students in using the LabVNC-based system reveal the potential to integrate the use of the LabVNC-based system with the practice of scientific experiments. Based on the feedback from the teacher and students, the existing LabVNC-based system will be refined under the design-based research approach.

How gender matters 普通类
Is the negative stereotype of women with regard to computer competence still exerting power in our society? In this study, 206 participants observed a target person (either a woman or a man) on a video who was about to solve a complex computer task. Participants had to estimate whether the target person was successful on this task in a limited amount of time. After they had received the information that the target person had solved the task successfully in the required time period, and that the person’s performance was above average, they were asked to provide a reason for the success (luck vs. skill attribution) and to evaluate the general computer competence of the target. Then, participants had to evaluate their own (hypothetical) computer competence in comparison to the target. Results suggest that for the direct evaluation of the target persons and for the causal attribution of success, no systematic gender-related biases occurred. In the self-ratings of participants; however, findings showed that (a) women judged their computer competence to be lower than did men, and (b) both women and men judged their own hypothetical performance in the computer-related task to be relatively higher when comparing it to the identically scripted performance of a woman vs. a man.
