Student ratings of instruction have been the subject of numerous studies with much of the research focusing on the validity and reliability of the ratings themselves. Comparatively little empirical investigation has been devoted to the perceptions of the individuals who are the subjects of the ratings, that is, the faculty. The current study explored faculty perspectives on the usefulness of student ratings for formative and summative purposes, and the actual use of student ratings for summative purposes. Contrary to what might have been deduced from the anecdotal literature, the results of this study do not portray a great deal of resistance to student ratings in general or to their use for formative and summative evaluation. It was also found that student ratings are actually being used for the latter purpose. The usefulness of the student feedback was viewed differentially by the faculty, with feedback on their interaction with students seen as most useful, followed by feedback on their grading practices, global ratings of instructor and course, and finally structural issues of the course. 相似文献

In this paper, we consider theories about processes of visual perception and perception-based knowledge representation (VPR)
in order to explain difficulties encountered in figural processing in junior high school geometry tasks. In order to analyze
such difficulties, we take advantage of the following perspectives of VPR: (1) Perceptual organization: Gestalt principles,
(2) recognition: bottom-up and top-down processing; and (3) representation of perception-based knowledge: verbal vs. pictorial
representation, mental images and hierarchical structure of images. Examples given in the paper were mostly taken from Gal's
study (2005) which aimed at identifying and analyzing Problematic Learning Situations (after Gal & Linchevski, 2000) in junior high school geometry classes. Gal's study (2005) suggests that while this theoretical perspective became part of teachers' pedagogic content knowledge, the teachers were
aware of their students' thinking processes and their ability to analyze and cope with their students’ difficulties in geometry
was improved. 相似文献

A cognitive gap between arithmetic and algebra 总被引：1，自引：0，他引：1
Serious attempts are being made to improve the students' preparation for algebra. However, without a clear-cut demarcation between arithmetic and algebra, most of these undertakings merely provide either an earlier introduction of the topic or simply spread it out over a longer period of instruction. The present study investigates the upper limits of the students' informal processes in the solution of first degree equations in one unknown prior to any instruction. The results indicate the existence of acognitive gap between arithmetic and algebra, a cognitive gap that can be characterized asthe students' inability to operate spontaneously with or on the unknown. Furthermore, the study reveals other difficulties of a pre-algebraic nature such as a tendency to detach a numeral from the preceding minus sign in the grouping of numerical terms and problems in the acceptance of the equal symbol to denote a decomposition into a difference as in 23=37–n which leads some students to read such equations from right to left.This research was funded by the Quebec Ministry of Education (Fonds FCAR-92-ER-1032).The authors wish to thank Patricia Lytle for her many helpful suggestions in the preparation of this paper. 相似文献

The objective of the teaching experiment reported in this article was to overcome the cognitive gap, that is, students' inability to spontaneously operate with or on the unknown. Following an analysis of the cognitive obstacles involved, this paper reports the results of an alternative approach. We designed an individualized teaching experiment which was tested in six case studies. In the first part the students' natural tendency to group singletons in the unknown within the equations was expanded to a process of grouping like terms. In the second part we introduced a reverse process to grouping like terms, that of decomposition of a term into a sum. This process, combined with the cancellation of identical terms, provides a procedure for the solution of first degree equations with the unknown on both sides of the equality sign. The last part of the teaching experiment involved the decomposition of an additive term into a difference. The first two parts proved very successful and the students developed procedures on their own that were more efficient than the initial ones. The results of the third part, however, revealed the limits of this approach. The students experienced difficulties in choosing the required decomposition. It seems that some of these obstacles are rather robust and perhaps should not be dealt with incidentally but should be addressed as part of a pre-algebra course.This research was funded by the Quebec Ministry of Education (Founds FCAR 92-ER-1032). 相似文献

We report here an instructional method designed to address the cognitive gaps in children's mathematical development where
operational conceptions give rise to structural conceptions (such as when the subtraction process leads to the negative number
concept). The method involves the linking of process and object conceptions through semiotic activity with models which first
record processes in situations outside mathematics and subsequently mediate activity with the signs of mathematics. We describe
two experiments in teaching integers, an interesting case in which previous literature has focused on the dichotomy between
the algebraic approach and the modelling approach to instruction. We conceptualise modelling as the transformation of outside-school
knowledge into school mathematics, and discuss the opportunities and difficulties involved.

The research on student ratings of instruction, while voluminous, has had minimal focus on the perceptions of the students who do the ratings. The current study explored student perspectives on course and teacher ratings as well as some issues related to teaching effectiveness and faculty roles. It was found that students are generally willing to do evaluations and to provide feedback, and have no particular fear of repercussions. However, they have little confidence that faculty or administrators pay attention to the results, and do not even consult the ratings themselves. The students view teaching and advising as the most important roles that should be played by faculty, yet project that faculty, while also viewing teaching as the most important, would rank research above the more student-interactive advising. Canonical correlations among various scales reveal a strong emphasis on such issues of the importance of faculty respect for student views. 相似文献

ABSTRACTContext-based learning (CBL), promoting students' scientific text comprehension, and fostering metacognitive skills, plays an important role in science education. Our study involves CBL through comprehension and analysis of adapted scientific articles. We developed a module which integrates metacognitive prompts for guiding students to monitor their understanding and improve their scientific text comprehension. We investigated the effect of these metacognitive prompts on scientific text comprehension as part of CBL in chemistry. About 670 high school chemistry students were randomly divided into three groups exposed to high- and low-intensity CBL. One of the high-intensity groups was also exposed to metacognitive prompts. Research tools included pre- and post-questionnaires aimed at measuring students' conceptual chemistry understanding and metacognitive knowledge in the context of reading strategies, before and after exposure to the CBL. Chemistry understanding was reflected by students' ability to identify the main subject of the adapted article and by explaining concepts both textually and visually. We found that high-intensity CBL combined with metacognitive prompts improved students' chemistry understanding of the adapted scientific articles and the ability to regulate their learning. Our study establishes that reading context-based adapted scientific articles advances students' conceptual chemistry understanding. These gains are strongly amplified by domain-specific metacognitive prompts. 相似文献

The unique contribution of grandparents to families of children with and without disabilities is often overlooked in the clinical and empirical literature. Perceptions and practice of teachers regarding grandparents were examined. Eighty‐two special education teachers and 80 teachers from regular classes completed a 30‐item questionnaire tapping perceptions of structural and functional aspects of grandparents’ support to parents, and actual practice with grandparents. Results show that, on the whole, few differences were found between special and regular education. Although teachers acknowledge the significant and stable role that grandparents play, they rarely translate this to actual practice. Moreover, more than half the teachers showed no interest in acquiring more professional training in this area. The findings present a challenge to educators and policy‐makers to be more attentive to the significant family resource of grandparents that is currently practically ignored. 相似文献

Algebraic symbols do not speak for themselves. What one actually sees in them depends on the requirements of the problem to which they are applied. Not less important, it depends on what one is able to perceive and prepared to notice. It is this last statement which becomes the leading theme of this article. The main focus is on the versatility and adaptability of student's algebraic knowledge.The analysis is carried out within the framework of the theory of reification according to which there is an inherent process-object duality in the majority of mathematical concepts. It is the basic tenet of our theory that the operational (process-oriented) conception emerges first and that the mathematical objects (structural conceptions) develop afterward through reification of the processes. There is much evidence showing that reification is difficult to achieve.The nature and the growth of algebraic thinking is first analyzed from an epistemological perspective supported by historical observations. Eventually, its development is presented as a sequence of ever more advanced transitions from operational to structural outlook. This model is subsequently applied to the individual learning. The focus is on two crucial transitions: from the purely operational algebra to the structural algebra of a fixed value (of an unknown) and then from here to the functional algebra (of a variable). The special difficulties experienced by the learner at both these junctions are illustrated with much empirical data coming from a broad range of sources. 相似文献
