About 1500 children from an inner city school district and a suburban school district were asked to perform eight tasks of basic skills. There were differences in the performances of the children. The differences depended upon the socio-economic background of the children. On many of the skills, third grade urban children were similar to first grade suburban children. It is for this reason that the inner city children in this study were considered disadvantaged and a program of skill development has begun. Inner city children must have experiences that will help them acquire the skills that suburban children have acquired before entering school. 相似文献

Teaching Basic Science and Clinical Medicine at a distance: An Evaluation of Satellite Communication
The evaluation plan arid preliminary results are reported for the ATS‐6 Satellite interactive telecommunication program for teaching at sites remote from an established medical school. The technical aspects of the system were seen as quite adequate and did not appear to substantially inhibit interaction. In the Fairbanks broadcasts analyzed, the average number of interactions ranged from 1.49 to 2.60 per minute. Ninety percent of the interaction flowed across the Satellite during Omak transmissions. Participants tended to initiate communication when they were on camera rather than when viewing their counterparts. Omak participants directed a higher percentage of the communication in student/resident programs (70%) than in faculty continuing education programs (59%). Interaction analysis indicated the categories of giving opinion, information, and suggestion were most frequent. Asking for opinion and suggestion occurred infrequently. The most frequent emotional expression was offering solidarity (e.g., reassurance), while there were exceedingly few expressions of disagreement, tension and antagonism. User acceptance of the system was determined to be very high. Participants with frequent exposure to the Satellite modality tended to have positive reaction. A significant difference in knowledge gain is reported in one of two basic science areas taught via Satellite as compared to regular instruction. 相似文献

Empirical analysis requires researchers to choose which variables to use as controls in their models. Theory should dictate this choice, yet often in social science there are several theories that may suggest the inclusion or exclusion of certain variables as controls. The result of this is that researchers may use different variables in their models and come to disparate conclusions with respect to predicted effects and their statistical significance. In such cases one is uncertain of which particular set of regressors forms the model that represents the data. The approach used below accounts for uncertainty in variable selection by using Bayesian model averaging (BMA). Accounting for uncertainty, we demonstrate that BMA provides better out-of-sample prediction for university graduation rates than results based on alternative variable selection methods. 相似文献

Information framing was investigated as a classroom management technique for academic task completion. Framing effect refers to the finding that people's choices are affected by how pre‐decisional information is framed (Tversky & Kahneman, 1984). In five 3rd and 4th Grade classrooms, teachers observed task completion rates of their students under five different framing conditions: unframed instruction; positively framed instruction with (a) group and (b) individual consequence; negatively framed instruction with (a) group and (b) individual consequence. Task completion rates were significantly greater under all framed instruction conditions than unframed, with effect sizes ranging from 0.21 to 0.32 and much greater at the class level. Improvement rates corresponding to effect sizes ranged from 20% to 70% at the class level, showing the usefulness of framing instructional directives. 相似文献

Executives recognize the value of maintaining access to information. More managers filter their own e-mail rather than have assistants do this task. Organizing and storing data for future use are left to the personal preference of the individual manager. Is this in the best interest of the organization? Are data being stored in a manner causing them to be irretrievable in the future? Are irrelevant data being stored? This study investigates the strategies used to store and retrieve e-mail. The results revealed that the primary search strategy was a reliance on memory. The labels assigned to the e-mail folders triggered the user's memory. Although, in the short term, memory is sufficient for organizing and retrieving information, the lack of transferability and preservation of this information poses a danger. The association between the electronic file label and the stored information is unique to the manager and may lead to inaccessibility of relevant corporate knowledge in the future. 相似文献

This study reports the results of a needs analysis of literacy programs for a library system serving three rural and suburban
counties. It examines the computing skills and needs of literacy tutors as well as native-speaking and English language learner
(ELL) literacy tutees enrolled in the programs. Paper surveys were mailed to tutors, who were asked to complete a survey themselves
and assist their tutees to complete one. Results of this study offer insights into the incorporation of digital literacy into
traditional adult literacy programs focusing on the needs, wants, and support systems of user groups. 相似文献

Students with LD who struggle with reading comprehension can benefit from instruction on how to read strategically. One strategy that has been demonstrated to increase reading comprehension is self‐questioning. In this study, two fifth graders with LD were taught to self‐generate questions using a prompt fading procedure. The participants were provided with expository reading passages with embedded questions. As each participant demonstrated proficiency with answering the embedded questions correctly, the embedded questions were systematically faded and replaced with a prompt for the students to generate their own questions. A multiple baseline across participants design demonstrated that the self‐questioning intervention resulted in improvements in reading comprehension for both students. Additionally, the students demonstrated evidence of maintenance and generalization of reading comprehension outcomes. 相似文献
