General experiences + race + racism = Work lives of Black faculty in postsecondary science education
Eileen R. C. Parsons Domonique L. Bulls Tonjua B. Freeman Malcolm B. Butler Mary M. Atwater 《Cultural Studies of Science Education》2018,13(2):371-394
Existent research indicates that postsecondary Black faculty members, who are sorely underrepresented in the academy especially in STEM fields, assume essential roles; chief among these roles is diversifying higher education. Their recruitment and retention become more challenging in light of research findings on work life for postsecondary faculty. Research has shown that postsecondary faculty members in general have become increasingly stressed and job satisfaction has declined with dissatisfaction with endeavors and work overload cited as major stressors. In addition to the stresses managed by higher education faculty at large, Black faculty must navigate diversity-related challenges. Illuminating and understanding their experiences can be instrumental in lessening stress and job dissatisfaction, outcomes that facilitate recruitment and retention. This study featured the experiences and perceptions of Black faculty in science education. This study, framed by critical race theory, examines two questions: What characterizes the work life of some Black faculty members who teach, research, and serve in science education? How are race and racism present in the experiences of these postsecondary Black faculty members? A phenomenological approach to the study situates the experiences of the Black participants as valid phenomena worthy of investigation, illuminates their experiences, and seeks to retain the authenticity of their voices. 相似文献

Age and Socialization Effects on the Development of Social Comparison Motives and Normative Ability Assessment in Kibbutz and Urban Children 总被引:1,自引:0,他引:1
We hypothesized that tendencies to explain interest in peers' work in terms of mastery-promotion or of relative ability assessment is related both to the development of the normative conception of ability and to educational emphases on cooperative or competitive learning goals. Study 1 tapped acquisition of the normative conception, normative self-assessment, and reasons for looking at others' work among 208 kibbutz and urban Israeli subjects at ages 4–8. Results confirmed that acquisition of normative understandings was associated with a shift from mastery to ability explanations in urban, but not kibbutz, children. Study 2 revealed similar differences in the frequency of mastery versus ability assessment reasons among 48 kibbutz and urban third-grade children asked to explain the videotaped glances of an unfamiliar child. Thus, cooperative learning settings seem to maintain interest in using peers to promote mastery, even after acquisition of the normative conception. 相似文献

This study investigated the effects of using different forms of computer-based feedback on high school students' learning of science material. The basic design consisted of two conditions of instructional support (text and questions vs. questions only), two testings (immediate vs. retention), five levels of similarity between lesson and posttest questions, and five feedback conditions: knowledge of correct response (KCR), delayed KCR, answer until correct (AUC), questions only (no feedback), and no questions. Results showed significant benefits for feedback over no feedback, with AUC becoming more advantageous and delayed feedback less so as lesson-posttest question similarity decreased. Also, with decreased question similarity and the availability of supporting text, overall feedback effects tended to decrease. The results are discussed in terms of the information processing effects of the different feedback forms, a factor that CBI designers often fail to exploit in planning feedback conditions.This article is based on a doctoral dissertation submitted to the faculty of Memphis State University by the first author.

Principals’ written assessments of 50 high school teachers whom they judged competent for full registration and 32 whom they judged not yet competent and in need of an extended period of provisional registration were analysed in terms of the characteristics used to describe and determine beginning teacher competence. It was found that principals consistently refer to a narrow range of characteristics when describing competent beginning teachers and focus on an even narrower range in deciding whether or not full registration should be granted. Characteristics that describe approaches to teaching are used most often in this regard. While the majority of beginning teachers possess an adequate knowledge base in their subject area, success in the first year of school experience hinges on the ability to communicate such knowledge and concepts to students. The need for further refinement of the appraisal process, including professional development programmes for principals, is highlighted. 相似文献

Many students have a deep interest in astronomy, but a limited opportunity to use telescopes to explore the heavens. The MicroObservatory Network of automated telescopes is designed to provide access to classroom teachers who wish their students to conduct projects over the World Wide Web. The intuitive interface makes it easy for even 10-year-olds to take pictures. Telescopes can be remotely pointed and focused: filters, field of view, and exposure times can be changed easily. Images are archived at the website, along with sample challenges and a user bulletin board, all of which encourage collaboration among schools. Wide geographic separation of instruments provides access to distant night skies during local daytime. Since first light in 1995, we have learned much about remote troubleshooting, designing for unattended use, and for acquiring the kinds of images that students desire. This network can be scaled up from its present capability of 240,000 images each year to provide telescope access for all US students with an interest in astronomy.

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

Black and White students who enrolled in college by age 20 were selected from a national probability sample, in order to estimate the prevalence of having children and the effect of having a child on probability of graduation with a bachelors degree. Black students reported significantly higher rates of having children than White students, but rates for Black students at historically Black universities were similar to those of Black students at predominantly White universities. After controlling for family background, achievement, and other student characteristics, having a child within 5 years of starting college generally reduced the probability of graduating with a bachelors degree for Black women and White women and men. The independent effect of attending a historically Black college was significantly positive for Black women but not statistically significant for Black men. 相似文献
