This multiple case study examined pre-service teachers perceptions of effective post-secondary instruction. Pre-service teachers
were asked to write essays describing an effective teacher of their choice. Twenty-one essays were randomly selected. Data
analysis involved open coding of each essay, content analysis of each essay using Anderson and Burns’ (Research in classrooms:
The study of teachers, teaching, and instruction (1st ed.). Oxford, England; New York: Pergamon Press, 1989) empirically derived
dimensions of instruction, and effect size analysis of student and teacher roles. Instructional components were identified
that differentiate between effective inquiry instruction and effective instruction. Effective inquiry instruction was associated
with more and different teacher and student roles, more activities as part of instruction, and more student small group discussion
than was effective instruction. 相似文献

This research investigated the impact of teacher questions, question types, and interaction patterns that coincide with high and low levels of constructivist teaching practices. Through both quantitative and qualitative methods the findings revealed that teachers facilitating classrooms with high levels of constructivist teaching practices (HLCTP) were very active as they asked a significantly greater number of questions compared to teachers facilitating classrooms with low levels of constructivists teaching practices (LLCTP). In addition, teachers facilitating with HLCTP used a significantly greater number of open‐ended questions when compared with other types of questions (closed‐ended questions and task‐oriented questions). Closed‐ended questions were found in the HLCTP classrooms as teachers were concerned with focusing students on completing investigations, but open‐ended questions were more often found with the aim of promoting student actions attuned to knowledge construction. 相似文献

The present study explores the relationship between students’ views of the nature of science (NOS) and their views of the nature of scientific measurement. A questionnaire with two‐tier diagnostic multiple‐choice items on both the NOS and measurement was administered to 179 first‐year physics students with diverse school experiences. Students’ views on the NOS were classified into four NOS ‘profiles’, and views on measurement were classified according to either the point or set paradigms. The findings show that students with a NOS profile dominated by a belief that the laws of nature are to be discovered by scientists are more likely to have a view of the nature of scientific measurement characterised by a belief in ‘true’ values. On the other hand, students who believe that scientific theories are inventions of scientists, constructed from observations that are then validated through further experimentation, are more likely to have a view of the nature of scientific measurement that is underpinned by the uncertain nature of scientific evidence. The implications for teaching scientific measurement at tertiary level are discussed. 相似文献

Education for national identity: Arab schools principals and teachers dilemmas and coping strategies
AbstractThis article discusses strategies used by Arab principals and teachers in Israel to cope with dilemmas involved in education for national identity stemming from conflict between two national narratives. While the Israeli Ministry of Education expects the Arab education system to educate students according to the Jewish State’s values, Palestinian Arab society expects its schools to educate its children according to Palestinian Arab national-cultural values. A qualitative research employed a semi-structured interview to elicit views on this issue from 7 principals and 14 teachers in the Arab education system in Israel. The findings indicate a conflictual reality. Interviewees expressed fear, humiliation and affront when required to obey Ministry of Education instructions in contradiction to attitudes prevalent in their society. They therefore developed coping strategies to foster students’ national identity without disrupting the necessary balance; primarily the construction of a covert learning program through manipulations in the official overt learning program. This study contributes to our understanding of minority education in a reality of conflict between the state and its national minority. 相似文献

The purpose of this study is to document the significance of four practices employed by parents that contribute to such development. Those practices encompassed the availability of materials, activities at home, parent attitude and visits to their child's class. Subjects consisted of 314 male and female parents of kindergarten children in the Sultanate of Oman. The researchers developed a 25-item questionnaire intended to measure the degree of parent involvement in their children's development at acceptable levels of validity and reliability. Results indicated that the role of parents ranged from medium to high on all practice domains of the tool. There were no significant differences for parents reading and writing practices, education levels, income levels, gender of children and siblings order. It is suggested that additional investigation in rural areas and other locales districts with different socially and economical levels should be conducted. In addition, the role of technology at homes and kindergartens such as child's learning style, parent's knowledge of child development and the availability of related outside resources available to families should be considered. 相似文献

This study evaluated the changes in ratios of different intensity (rating of perceived exertion; RPE, heart rate; HR, power output; PO) and load measures (session-RPE; sRPE, individualized TRIMP; iTRIMP, Training Stress Score?; TSS) in professional cyclists. RPE, PO and HR data was collected from twelve professional cyclists (VO2max 75 ± 6 ml?min?kg?1) during a two-week baseline training period and during two cycling Grand Tours. Subjective:objective intensity (RPE:HR, RPE:PO) and load (sRPE:iTRIMP, sRPE:TSS) ratios and external:internal intensity (PO:HR) and load (TSS:iTRIMP) ratios were calculated for every session. Moderate to large increases in the RPE:HR, RPE:PO and sRPE:TSS ratios (d = 0.79–1.79) and small increases in the PO:HR and sRPE:iTRIMP ratio (d = 0.21–0.41) were observed during Grand Tours compared to baseline training data. Differences in the TSS:iTRIMP ratio were trivial to small (d = 0.03–0.27). Small to moderate week-to-week changes (d = 0.21–0.63) in the PO:HR, RPE:PO, RPE:HR, TSS:iTRIMP, sRPE:iTRIMP and sRPE:TSS were observed during the Grand Tour. Concluding, this study shows the value of using ratios of intensity and load measures in monitoring cyclists. Increases in ratios could reflect progressive fatigue that is not readily detected by changes in solitary intensity/load measures. 相似文献

Following past researches, student background, learning strategies, self-related cognitions in mathematics and school climate variables were important for achievement. The purpose of this study was to identify a number of factors that represent the relationship among sets of interrelated variables using principal component factor analysis and examine the contribution of each factor to the explanation of the variance in the students' mathematics score using multiple regression analysis. The sample was prepared from students who participated in Programme for International Student Assessment (PISA) in Turkey. These data consisted of 3765 15 year-old Turkish students in 158 schools. The results showed that four factors under study totally accounted for approximately 34 percent of the variance in mathematics achievement. All of the factors had statistically significant effects on the achievement. The findings are very important for Turkish education system because the fact that changing school climate and improving the learning strategies are much easier to achieve than changing background factors affecting students' performance. 相似文献

The research reported in this article investigated the effect of manufacturing strategy on organizational performance in the Malaysian electrical and electronic sector. It was revealed that a cost‐based strategy greatly affected the performance of organizations participating in this study. This result implied that a cost‐based strategy is still a dominant concern for manufacturing firms. The information gathered through this study is useful for strategy formulation and for understanding how a strategy can lead to improved organizational performance in general. 相似文献

Antitryptic, antichymotryptic and alpha 2- macroglobulin activities were measured in sera of normal nonpregnant and normal
pregnant women and women with tubal ectopic pregnancy and molar pregnancies in the first 5 to 7 weeks of pregnancy calculated
from the last menstrual period. While alpha 2-macroglobulin decreased in early normal pregnancy compared to nonpregnant state
(p<0.001), in ectopic and molar pregnancies there was an increase in alpha 2- macroglobulin activity (p < 0.001), as compared
to nonpregnant and normal pregnant women. Antitryptic activity did not increase in normal and ectopic pregnancy, however was
increased in molar pregnancy (p < 0.01). Antichymotryptic activities did not show a change either in normal pregnancy or in
cases of ectopic and molar pregnancy. Drop in alpha 2- macroglobulin activity to near normal levels in ectopic, 6 weeks post
surgery, correlated well with the decrease in β-hCG. However, in molar pregnancy, alpha 2- macroglobulin remained elevated
even when the β-hCG levels in serum returned to zero 10 weeks after surgery. The studies suggest a major role for circulating
proteinase inhibitors especially alpha 2-macroglobulin in regulating proteinase activity in normal, ectopic and molar pregnancy. 相似文献

The purpose of the study was to test a structural model which involves training variables and work environment variables in the United Arab Emirates and Jordan. Two instruments were used to collect data from people with a disability (n = 113) about their views of the training program and work environment. The Structural Equation Model (SEM) analysis revealed the following results: the factor representing psychological support and suitability of training environment influenced positively the disabled workers' view of their work; the factor representing job selection, trainers, and efficacy of program had a negative effect on the view of the people with disability on their work environment; while job selection had a direct negative effect on how others perceive the disabled person. 相似文献
