One of the strongest instructional interventions documented in educational literature is the use of feedback to influence learning outcomes. However, there is lack of empirical research specifically pertaining to the use of multimedia in the feedback message. The purpose of this research was to test whether organizational pictures and modality as a feedback strategy had an effect on learner comprehension and satisfaction. The research design was a 2 Multimedia (Picture Present vs. Picture Absent) × 2 Modality (Narration vs. On-screen Text) × Trial (Trial 1 vs. Trial 2) with Multimedia and Modality serving as between-subject conditions and Trial serving as a repeated measure. One-hundred fifteen university students participated in the study. Findings show statistically significant increases in comprehension scores from Trial 1 to Trial 2 assessments for all four treatment conditions. Learners in the Picture present conditions were statistically more satisfied with the learning experience. Additionally, we used eye-tracking to verify the extent to which the pictures were used in the feedback message. A discussion and recommendations for future research and feedback design are provided. 相似文献

This paper explores recent trends in the size of scientific teams and in institutional collaborations. The data derive from 2.4 million scientific papers written in 110 top U.S. research universities over the period 1981-1999. The top 110 account for a large share of published basic research conducted in the U.S. during this time.We measure team size by the number of authors on a scientific paper. Using this measure we find that team size increases by 50% over the 19-year period. We supplement team size with measures of domestic and foreign institutional collaborations, which capture the geographic dispersion of team workers. The time series evidence suggests that the trend towards more geographically dispersed scientific teams accelerates beginning with papers published at the start of the 1990s. This acceleration suggests a sharp decline in the cost of collaboration. Our hypothesis is that the decline is due to the deployment of the National Science Foundation's NSFNET and its connection to networks in Europe and Japan after 1987.Using a panel of top university departments we also find that private universities and departments whose scientists have earned prestigious awards participate in larger teams, as do departments that have larger amounts of federal funding. Placement of former graduate students is a key determinant of institutional collaborations, especially collaborations with firms and with foreign scientific institutions. Finally, the evidence suggests that scientific output and influence increase with team size and that influence rises along with institutional collaborations. Since increasing team size implies an increase in the division of labor, these results suggest that scientific productivity increases with the scientific division of labor. 相似文献

This article provides a review of the contemporary instructional leadership research base in Malaysia. The core aim of this review is to assess the recent knowledge base on instructional leadership in Malaysia and to evaluate its current contribution to the existing international literature. The article explores a range of published material that has focused explicitly on instructional leadership and instructional leadership practices in Malaysia, including that written in Bahasa Malaysia. The article outlines the findings from the review and highlights certain strengths and limitations. The article concludes by identifying areas for further enquiry and investigation. 相似文献

This paper presents the story of a mathematics teacher's transformation that resulted from her engagement in collaborative action research. The collaborative research, conducted by a university mathematics educator and an eighth-grade mathematics teacher (Marylin), centered on investigating the outcomes of implementing a Hands-On Equations approach to teaching algebra. This algebraic study, which is briefly reported herein, serves as a vehicle for examining the questions, reflections, and changes brought forth by Marylin throughout the collaborative process. Thus, the project of investigating the teaching and learning of algebra can be viewed as the sub-study within the broader study of the effects of collaborative action research on the mathematics teacher involved in the investigation. Within this paper, issues related to the broader study of collaborative action research in the mathematics classroom, that are connected to Marylin's transformation, are discussed. These issues include the characterization of and goals for collaborative action research as well as the challenges for collaborative action research in mathematics classrooms.This revised version was published online in September 2005 with corrections to the Cover Date. 相似文献

This study examined the contributions of the different components of the working memory (WM) model to a range of mathematical skills in children, using measures of WM function that did not involve numerical stimuli. A sample of 148 children (78 Year 3, mean age 8 years and 1 month, and 70 Year 5 pupils, mean age 9 years and 10 months) completed WM measures and age‐appropriate mathematics tests designed to assess four mathematical skills defined by the National Curriculum for England. Visuo‐spatial sketchpad and central executive, but not phonological loop, scores predicted unique variance in children’s curriculum‐based mathematical attainment but the relative contributions of each component did not vary much across the different skills. Subsequently, the mathematics data were re‐analysed using cluster analysis and new performance‐related mathematics factors were derived. All three components of WM predicted unique variance in these performance‐related skills, but revealed a markedly distinct pattern of associations across the two age groups. In particular, the data indicated a stronger role for the visuo‐spatial sketchpad in the younger children’s mathematics performance. We discuss our findings in terms of the importance of WM in the development of early mathematical ability. 相似文献
