In 2011 the Integrated Strategic Planning Framework for Teacher Education and Development in South Africa was promulgated. This framework proposes the establishment of teaching schools to strengthen pre-service teacher education. This study arises from this initiative. A generic qualitative study was undertaken to explore the views of research participants from selected teacher education institutions and schools in South Africa on the potential of teaching schools to enable student teacher learning for the teaching profession. The key findings are that teaching schools can potentially make a distinctive contribution towards enabling student teacher learning for the teaching profession through student teachers experiencing good teaching in a model environment and through coordinating experiences in coursework and at the school. The discussion of the findings points to the distinctive potentialities of teaching schools for strengthening teacher education. The notion of hybridity and third space is invoked as a heuristic to shed light on the developing of a true collaborative relationship between the teacher education institution and the teaching school for enabling student teacher learning for the teaching profession. 相似文献

AbstractReferring to Haraway’s concept of tentacularity, this article embarks on a curious research practice-inspired speculative journey to think with material tentacular becomings in an Australian kindergarten. Some of the questions that guided our curious research practice asked: How does curious practice as a postqualitative methodology enable us, as researchers, to cultivate a presence that creates the conditions for these research encounters and events to be perceived? What becomes possible for generative relational diverse learning with matter-energies if we accept that there is no rational explanation at hand? What worlds come into being if we speculate instead of rationalize? How do children animate, and are animated relationally, in particular worlds and not in others? How do we, as researchers, become entangled within children’s ways of perceiving and naming encounters? We experimented with Haraway’s notion of tentacularity as our navigational tool to map four entangled territories in this article. 相似文献

Undergraduate students are often expected to be participants in academic research. However, decisions relating to student participation in research are typically based on speculation or educator assumptions rather than a solid research base. We conducted three studies to investigate student experiences of research participation. These included online surveys (Study 1), semi-structured interviews (Study 2), and analysis of reflective essays (Study 3). A range of pedagogic and ethical issues were considered including motivation to participate, distress, and the educational value of participation. Findings suggest that the experience provides students with important opportunities to learn about research methodology and ethical issues which inform their own research practice. Further, students cite additional non-academic benefits of research participation such as self-discovery and networking opportunities. Negative experiences typically consisted of nervousness prior to the first laboratory study or boredom, though for some students (e.g. those uncomfortable in social situations) engagement in research may lead to anxiety. We conclude that participation in research has pedagogic value to students, and educators should promote those elements of the research experience (e.g. critiquing studies, networking with researchers) that are most beneficial. However, researchers and educators should also actively work to reduce apprehension and minimise potential distress. 相似文献

Retinopathy of prematurity (ROP) is a major cause of blindness in children. Free radicals are implicated in the development of this retinopathy. We studied the role of free radicals in ROP and enrolled 60 preterm neonates at 30–32 weeks age. Thirty neonates predisposed to development of ROP, were placed in study group and 30 normal neonates in control group. Malondialdehyde and antioxidant enzymes superoxide dismutase (SOD) and glutathione peroxidase (GPX) were measured in blood spectrophotometrically. Both the groups were followed-up to 40–42 weeks age. Serum MDA levels, erythrocyte SOD and plasma GPX were significantly high in study group at 30–32 weeks as compared to control group. At follow up visit significant increase in MDA level and decrease in SOD and GPX level among the study group was seen. This disturbance in equilibrium of oxidant and antioxidant status initiates an inflammatory process in retinal tissue leading to development of ROP. 相似文献

Increased oxidative stress is a widely accepted participant in the development and progression of diabetes and its complications.
The present study has been undertaken to evaluate oxidative stress in type 2 diabetes mellitus and effect of vitamin E supplementation
on oxidative stress. In all 120 subjects were enrolled in the present study, 40 subjects are age and sex matched controls.
Test group comprised of clinically diagnosed (n = 80) type 2 diabetic patients. Biochemical parameters like serum MDA, nitric oxide, superoxide dismutase, erythrocyte reduced
glutathione and platelet aggregation were analyzed in control and diabetic group. Test group is further categorized as Group
I (n = 40) diabetics were treated by only hypoglycemic drugs and Group II (n = 40) diabetics were treated by hypoglycemic drugs with vitamin E supplementation. All above biochemical parameters were
again reassessed after 3 months follow-up in both group and its values were compared with its respective baseline levels.
The study shows, reduction of oxidative stress, improvement in antioxidant enzymes and endothelial dysfunction in group II,
those were on treatment of hypoglycemic drugs along with vitamin E supplementation. Hence the present study may conclude that
vitamin E supplementation along with hypoglycemic drugs may be beneficial to type 2 DM patients to minimize vascular complications. 相似文献

Student ratings of satisfaction with feedback are consistently lower than other teaching and learning elements within the UK higher education sector. However, reasons for this dissatisfaction are often unclear to teaching staff, who believe their students are receiving timely, extensive and informative feedback. This study explores possible explanations for this mismatch between staff and students’ perceptions of feedback quality. One hundred and sixty-six first year undergraduate students completed a questionnaire detailing their experiences of feedback on coursework before and throughout their first year at university. Results indicate that whilst procedural elements of feedback (timeliness and legibility) are considered satisfactory, past experiences (pre-university) may influence student expectations of feedback. Some students had a severe, negative emotional response to the feedback provided and few students engaged in self-help (independent learning) behaviours to improve their performance following feedback. We consider how changes in feedback practices could improve students’ use of, and satisfaction with, their feedback. 相似文献

Glutathione, the dominant intracellular thiol, plays an important protective role against oxidative stress. The accidental
findings of increased reduced glutathione level postprandially as compared to post absorptive level prompted the design of
present study. Reduced Glutathione levels were estimated in 50 healthy individuals in post absorptive and postprandial phase
by taking whole blood in ACD bulb. Mean postprandial reduced Glutathione (9.60±3.39 μmole/gm of Hb) is significantly increased
than mean postabsorptive level (5.53±0.88 μmole/gm of Hb; p<0.001). It also shows positive correlation (r=0.65) between these
two GSH levels. So present study suggests that post absorptive specimen collection is preferable over random or postprandial
as the former reflects the true basal level of reduced glutathione. 相似文献
