This study tested the assumption that the effectiveness of feedback with regard to performance, motivation, and affect is moderated by the learners’ self-concept. A total of 72 sixth-graders completed a web-based interactive learning program. Half of the sample received feedback and the other half received no feedback. Differential feedback effects were detected. For students with a positive academic self-concept, feedback led to a decline in performance and in mood but an increase in effort. With regard to participants with a negative self-concept, feedback worked against the decrease in mood but did not increase performance and motivation. These findings support the claim that feedback effects should be assessed with regard to (1) multiple dimensions and (2) possible moderating variables. 相似文献

In this article, we describe the rationale, design and evaluation of a widget-based dashboard to support scholars’ awareness of their Research Networks. We introduce the concept of a Research Network and discuss Personal Research Environments that are built of as a development parallel to Personal Learning Environments. Based on the results of an international interview study, we report on the design of a paper prototype of an awareness dashboard (AWESOME). Research in the Internet age has changed; the dashboard is tailor-made for use in modern research. We compared existing scholarly toolsets with our paper prototype. The evaluation of the user tests shows that, on all tested items, AWESOME performs better than the existing toolsets: it is easier to use, less time-consuming, more user-friendly, more supportive with regards to technology and awareness and, finally, helps researchers to carry out their tasks more effectively. 相似文献

Interactive and non-interactive pictures in multimedia learning environments: Effects on learning outcomes and learning efficiency 总被引:2,自引:2,他引:0
New technologies enable flexible combinations of text and interactive or non-interactive pictures. The aim of the present study was to investigate (a) whether adding pictures to texts is generally beneficial for learning or whether it can also have detrimental effects, (b) how interactivity of pictures affects learning, (c) whether the visualization format of pictures affects the structure of the learner's mental model, and (d) whether the visualization format modifies the effects of interactivity. One hundred university students were randomly assigned to five groups. In four groups, a text about the different daytimes and days on the earth was combined with interactive or non-interactive pictures of different visualization formats. In the fifth group, the text was presented without pictures. According to the results, adding pictures to text was neither beneficial nor harmful for learning. In terms of learning efficiency, however, learning from text only was more successful than learning from text and pictures. Interactivity was beneficial for one learning task, but not for the other task. The visualization format affected participants’ interaction with pictures, but not the learning outcomes; however this effect was not influenced by interactivity. Implications for multimedia design and for further research are pointed out. 相似文献

This article reports results of a four-year longitudinal study that investigated the impact of specific and non-specific precursors on mathematical school achievement. Preschool quantity-number competencies (QNC) predicted mathematical achievement in primary school. Furthermore, basic arithmetic fact retrieval in Grade 1 had an impact on early mathematics school achievement. The influence of socioeconomic status and number naming speed, assessed in kindergarten, became especially important at the end of Grade 4. Particularly, a subgroup of mathematically low-achieving children in Grade 4 had already performed more poorly than normal children in tasks assessing preschool QNC, number naming speed, and basic arithmetic fact retrieval, as well as nonverbal intelligence and socioeconomic status. 相似文献
