The purpose of this study was to analyze a five-week graduate-level education course taught entirely at a distance via the
Internet using the Blackboard.comSM e-learning system, with emphasis on exploring the dynamics of sense of classroom community. Subjects were 20 adult learners,
evenly divided between males and females, who were administered the sense of classroom community index at the beginning and
end of the course in order to measure classroom community. Findings indicated that on-line learners took advantage of the
“learn anytime” characteristics of the Internet by accessing the course seven days per week, 24 hours per day. Sense of classroom
community grew significantly during the course. Females manifested a stronger sense of community than their male counterparts
both at the start and end of the course. Additionally, female students exhibited a mostly connected communication pattern
while the communication pattern of males was mostly independent. 相似文献

ABSTRACTThis article describes how the University of Utah's J. Willard Marriott Library implemented a competency-based talent management system across the organization to address organizational, departmental, and individual needs. Success of the implementation was mixed. Designing human resources systems around core competencies made organizational values and goals concrete but proved unsustainable in the long-term. Using core competencies to shape departmental goals, coach staff and library faculty, and onboard new employees proved beneficial at the middle management level. 相似文献

Twenty-four mathematics teachers were asked to think aloud when posing a word problem whose solution could be found by computing 4/5 divided by 2/3. The data consisted of verbal protocols along with the written notes made by the subjects. The qualitative analysis of the data was focused on identifying the structures of the problems produced and the associated ways of thinking involved in constructing the problems. The results suggest that success in doing the interview task was associated with perception the given fractions as operands for the division operation and, at the same time, the divisor 2/3 as an operator acting over 4/5. The lack of success was associated with perception of division of fractions as division of divisions of whole numbers and using the result of division of fractions as the only reference point. The study sheds new light on the teachers’ difficulties with conceptualization of fractions. 相似文献

A closer look at split visual attention in system- and self-paced instruction in multimedia learning
Two experiments examined visual attention distribution in learning from text and pictures. Participants watched a 16-step multimedia instruction on the formation of lightning. In Experiment 1 (N = 90) the instruction was system-paced (fast, medium, slow pace), while it was self-paced in Experiment 2 (N = 31). In both experiments the text modality was varied (written, spoken). During learning, the participants’ eye movements were recorded. Results from both experiments revealed that learners spent more time studying the visualizations with spoken text than those with written text. In written text conditions learners consistently started reading before alternating between text and visualization; moreover, they spent more time reading the text than inspecting the visualizations. While in Experiment 1 additional time that was made available in conditions with a slow or medium instruction pace was spent inspecting visualizations, in Experiment 2 longer learning times resulted from reading the text more intensively. With respect to learning outcomes (retention, transfer, and visual memory) Experiment 1 revealed an effect of text modality for visual memory only. In Experiment 2 no modality effects were found. Instruction pace was hardly related to learning outcomes. Overall, the results confirm prior findings suggesting that the distribution of visual attention in multimedia learning is largely guided by the text. 相似文献
