In this paper, we have developed a classification model for online learning environments that relates the Instructors Overall Performance (IOP) rating (according to students’ perceptions) with the course characteristics, students’ demographics and the effectiveness of the instructor in his/her teaching roles. To that end, a comprehensive Student Evaluation of Teaching (SET) instrument is proposed, which includes not only conventional teaching elements, but also items that encourage twenty-first century skills. The goal of the study is twofold: (i) to quantify the extent to which the selected variables explain the IOP rating, and (ii) determine which teaching and non-teaching variables most affect the IOP rating. The best performing classifier achieved a competitive accuracy, highlighting that the selected variables mainly determine the IOP values. Other important findings include: (i) the IOP value is mainly influenced by the effectiveness of the instructor in his/her teaching roles; (ii) teaching strategies that involve the cooperation between the technical and pedagogical roles should be promoted; (iii) the pedagogical role has the highest impact on the final IOP value; and (iv) the most influential demographic variable is the student’s status (working commitments and family responsibilities). 相似文献

A surprising result of the Third International Mathematics and Science Study (TIMSS) is that computer use was negatively associated with high student achievement in some countries. More specifically, the students from all three countries who indicated that they use computers in the classroom most frequently were those with the lowest achievement on the TIMSS in 1995. For the purpose of this study, a similar comparison was made for 15-year-old U.S.A. students, based on the data from the Program for International Student Assessment (PISA). The results of this study show that it is not computer use itself that has a positive or negative effect on the science achievement of students, but the way in which computers are used. For example, after controlling for the student's socioeconomic status in the United States of America, the results indicated that the students who used computers frequently at home, including for the purpose of writing papers, tended to have higher science achievement. However, the results of this study also show that science achievement was negatively related to the use of certain types of educational software. This indicates a result similar to that found in the TIMSS data, which might reflect the fact that teachers assign the use of the computer and of educational software to the lower achieving students more frequently, so that these students can obtain more personal and direct feedback through educational software. 相似文献

AN EMPIRICAL INVESTIGATION OF DIFFERENCES BETWEEN MATHEMATICS SPECIALISTS AND NON-SPECIALISTS AT THE HIGH-SCHOOL LEVEL in
Cyprus – The data obtained from high-school seniors for the Third International Mathematics and Science Study (TIMSS) for
the country of Cyprus appear to be contradictory. Although Cypriot students did not perform well in mathematics in elementary
school, middle school, and in the non-advanced sectors of high school, students in advanced mathematics courses in high school
managed to perform exceptionally well. In seeking to account for this apparent disparity, the present study examines the differences
between mathematics specialists and non-specialists at the high-school level and discusses the implications that these have
for teaching practice. It shows how students educated in an environment that might not be optimal for producing high-achieving
students in mathematics and science in elementary and middle school (according to the TIMSS) might nonetheless manage to excel
in these fields at the end of their schooling. In conclusion, the authors address the implications of their study for similar
educational systems in other developing countries. 相似文献

ITERS (Infant and Toddler Environment Rating Scale), ECERS (Early Childhood Environment Rating Scale) and SACERS (School Age Care Environment Rating Scale) are used to measure process quality. The psychometric characteristics of the three scales are established, and high reliability and adequate validity are observed. The global quality process for the classrooms under study is less than good; process quality based on the direct interaction of adults with children in the classroom is better when compared with quality related to the experiences that children have with learning materials, equipment and space. The associations between child development outcomes and childcare quality are examined. Vocabulary, social development and adaptive behaviour show a strong and positive association with ECERS. Hierarchical regression analyses show that preschool quality has a significant and persistent effect in the variation of child outcomes (5%). These effects are maintained three years later, when children are in primary school (8%). 相似文献

After a short introduction to the Italian context relating to science teachers’ training and updating course we explain the motives that led us to produce educational material based on interactive methodologies (role‐playing) and to present it to in‐service teachers during updating courses. The role‐playing activities that we prepared draw from specific historical and geographical situations in order to face the problems of global environmental issues, such as, for example, water resources management, waste‐disposal, reforestation techniques. Some observations on the didactic effect of our proposals and on the importance of encouraging a change in the teachers’ way of thinking are presented. The latter is a prerequisite for a correct use of the educational material supplied. This means introducing a problematic concept of scientific knowledge and stimulating new attitudes to establish less hierarchic inter‐relations in class. 相似文献

AbstractIf service-learning is to fulfil its potential to contribute to meaningful social change, scholars and practitioners must consider how service might foster a dynamic relationship between knowledge, the learner and the community. This paper challenges modernist conceptions of knowledge as a ‘commodity’ that can be delivered and consumed, and instead identifies service to the community as a meaningful context for learners to interact with knowledge in a coherent framework for the explicit purpose of individual and social change. The Preparation for Social Action programme in Uganda is offered as an example in which relationships between knowledge, learners and the community can be examined. Findings from an analysis of curricular materials, participant observation and interview and focus-group data collected from its local instructors and administrators are discussed. 相似文献

This study tested the hypothesis that infants with iron-deficiency anemia show behaviors, such as increased proximity to caregivers, increased wariness or hesitance, and decreased activity, that could contribute to “functional isolation.” The behavior of 52 Costa Rican 12- to 23-month-old infants with iron-deficiency anemia was contrasted with that of 139 comparison group infants with better iron status during free play and mental and motor testing and in the home. Infants with iron-deficiency anemia maintained closer contact with caregivers; showed less pleasure and delight; were more wary, hesitant, and easily tired; made fewer attempts at test items; were less attentive to instructions and demonstrations; and were less playful. Adult behavior also differed. The results indicate that iron-deficiency anemia in infancy is associated with alterations in affect and activity, suggesting that functional isolation is a useful framework for understanding poorer developmental outcome in iron-deficiency anemia, the world's most common single nutrient deficiency. 相似文献
