This study aimed at establishing if the level of performance of 500 Jamaican Grade 11 students on an achievement test on the concept of respiration was satisfactory (mean=28 or 70% and above) or not (<70%); if there were statistically significant differences in their performance on the concept linked to their gender, cognitive abilities in biology, self-esteem, school location, socioeconomic background (SEB), school-type and school location; and if there were significant relationships among the six variables and the students’ performance. The sample (n=500) consisted of 212 boys and 288 girls selected from five all-boys’ schools (119 students), five all-girls’ schools (159 students), and six coeducational schools (222 students). The students were from six rural schools (137 students) and ten urban schools (363 students), out of which 291 were from a high SEB and 209 were from a low SEB. A 40-item multiple choice test on respiration and a self-esteem questionnaire were used to collect data. The results revealed that the students’ level of performance (mean=23.44 or 58.60%, SD=6.86) was regarded as fairly satisfactory; there were statistically significant differences in the students’ performance on respiration based on their cognitive abilities, and school-type in favour of students with high cognitive ability in biology and all-boys’ schools respectively. There was a positive statistically significant but weak relationship between the students’ (a) cognitive abilities, and (b) school-type and their performance on respiration. 相似文献

Eight teachers were interviewed concerning how students verify conjectures. The study is a sequel to a previous study, “How Students Verify Conjectures” [Bergqvist, T. (2000). How students verify conjectures. Research reports in Mathematics Education 3]. Teachers’ expectations of students’ reasoning and performance are examined, and also how they wish students would work. The results indicate that the teachers tend to underestimate the students’ reasoning levels and that they believe that only a small group of students in each class can use higher level reasoning in mathematics. 相似文献

In the present study, we develop and deploy a conceptual framework of “scaffolding” in groupwork learning, through the analysis of the pursuit of a learning goal over time. The analysis follows individuals’ different experiences of an interaction as well as collective experiences, considering individual attainment as a result of a bi-directional contextualized conversation and action. We detect, describe and evaluate two (2) types of interaction that can be characterized as “scaffolding process”: the first concerns “Scaffolding individual thinking” and the second “Scaffolding collective thinking”. The latter, apart from presenting the educational advantages of collective thinking through peer discussion (D) and curriculum-focused evaluation context of Teacher Initiation – Student Response – Teacher Follow up (IRF), also presents the advantage of ‘spiral’ verbal exchanges in which the teacher “tunes in” to the students’ present state of ability or understanding (spiral IDRF). 相似文献

This study details the development and results of a campus-based writing assessment plan that was mandated by a state-wide university system in order to explore the “value-added” from a writing program curriculum to undergraduate students’ competence with written expression. Four writing samples (two timed essays and two conventional essays) that are produced before, during and at the close of enrollment in the writing program are scored for critical thinking, genre knowledge, rhetorical skills, and mechanics. The results indicate that local campus student achievement related to writing is comparable with performance captured by nationally normed technologies and larger assessment projects at similar state universities. The data also suggest significant performance difference related to the institutional position of students’ instructors as well as students’ own enrollment status. The article concludes that while the data produced by this research project are compelling, the policy and political implications of the undertaking suggest greater sensitivity to the institution's culture and program direction as well as its impact on instructor morale, student learning environment and the place of composition studies in the university. 相似文献

The paper presents a case study of a secondary school in Israel and its efforts at attending to students’ needs without resorting to tracking and ability grouping. It explores an organisational process the school has established, called “Opening triads”, which involves periodical regrouping of three classrooms of students of the same age and same subject matter into three new groups. The findings suggest that ability grouping is difficult to eliminate, but there are alternatives that may reduce its social and emotional harmful effect. Ability grouping can be avoided altogether through other, more equalitarian forms of regrouping students. 相似文献

Are students’ mathematical procedures as unstable as they seem? Students often produce different errors in response to the same kind of problems on different testing occasions. This finding is puzzling. Past research has shown that students induce overly general procedures from worked-out examples during learning, which lead to a host of predictable errors on new problems. Do students create rule-based errors only to then switch between them at random? In this paper, we show that seemingly diverse errors on two different testing episodes may result from the same underlying stable procedure and are part of the same error category. These findings suggest that students’ errors are more stable on a category vs. on an individual level. The current study consists of teaching students addition in a new number system, called NewRoman, and analyzing students’ solution strategies in detail. Implications for teaching are discussed. 相似文献

This paper will consider ways to study educational reform efforts in order to allow policy-making to be developed on a relatively sound basis. At present, educational policy-making often derives from a pastiche of available anecdotes, research-based “good” ideas, and previous administrative guidelines. Educational evaluation efforts should not be used merely to identify and label programs as either “successes” or “failures” at a global level, but rather to permit the analyses of elements or components of programs which seem to be making positive contributions to a common sense perception of program success. A comprehensive, developmental sequence for such evaluation will be described. 相似文献

Since Grossman’s seminal paper in 1972, there have been a number of studies concerning the effect of education on health and health care demand. Though several studies have distinguished between preventive and curative care, no study has investigated the effects of general education on the utilization of unnecessary emergency department use. We test whether general education reduces “potentially unnecessary” emergency department utilization and provide a measure of the resulting private benefits associated with increased education. Our results partially confirm our hypothesis regarding “potentially unnecessary” emergency department use. We find that moving from a high school to greater than high school education appears to reduce “potentially unnecessary” emergency department use, with the impact being greater among the insured. However, though reducing the education level from high school to less than high school increases “potentially unnecessary” emergency department use among the insured as predicted, it has the opposite impact on the uninsured. 相似文献

The paper reports a cross-cultural investigation conducted in 2001–2002 that seeks to reveal students’ alternative ideas in two countries, Taiwan and Germany. It was carried out by means of semi-structured interviews in a story form. The targeted students were arbitrarily selected from grades 3 to 6 in both countries and amounted to 64. The questions in the interview were centered around “the heavens” (space, heavenly bodies, and familiar astronomical events) and “the earth” (the appearance, shape, movement, and, in some cases, gravity). The results indicated that, first, the students presented their ideas in a consistent manner, regardless of their cultural backgrounds, if we take into account the scope of questions and phenomena which were in their concern or of their interest. The comments from the student can be patterned into a structure-like whole, which we term “model” in the study. Second, the alternative models of “the heavens and the earth” elicited in the interviews appear to have various strengths of explaining familiar astronomical events. Interestingly, the more advanced a model is (in regard with the present-day cosmological model), the higher explanatory power it contains. As for the difference between the sample of two countries, the German students show more intention (or are more aware of the need) to explain astronomical phenomena than their Taiwanese counterparts, and thereby presented more precise models with stronger explanatory power. On the other hand, the Taiwanese students appeared to have more imagination and conceptual flexibility that should also be valued. 相似文献

Although well established in a range of situations, the application of operant methodologies to typical classrooms is often difficult for teachers because of logistic considerations which may lead to a subgroup of a class being rewarded, with peers showing performance decrement. This paper reviews the use of “vicarious” and “implicit” rewards in both special and normal classrooms, critically examining previous literature and concluding that several key issues are open to speculation. A series of four further studies which were designed to investigate some of these issues and overcome some of the design and methodology flaws of previous research are reported, with several important distinctions being drawn between “vicarious reinforcement” effects and outcomes from “implicit reward” situations. Criterion variables are discussed, with several key findings suggesting that the concept of vicarious reinforcement as based upon the general literature is simplistic and inaccurate. Suggestions are made for the successful use of “implicit reward” procedures in the classroom. 相似文献

An important question that must be answered is whether cognitive styles, abilities, and aptitudes provide complementary or redundant information regarding students' characteristics. Measures of 6 styles, 6 abilities, and 12 aptitudes were administered to 201 Navy recruits. Relationships among all cognitive attributes and between sets of styles and abilities as well as styles and aptitudes were examined by computing product-moment correlations and two canonical analyses. A principal-factor analysis and varimax rotation were also computed for all 24 characteristics. The results indicated that many styles are significantly related to abilities and aptitudes. However, the amount of shared variance between styles and abilities or aptitudes is small. Three significant factors were extracted (i.e., technical aptitude, verbal ability, and general problem solving) which underlie much of the variability of these cognitive characteristics. The data demonstrated (1) the relative dependence of most cognitive styles with abilities and aptitudes inherent to general problem solving, and (2) the relative independence of some cognitive styles from technical aptitude and verbal ability dimensions. 相似文献

This paper reports findings from a study of undergraduates’ expectations about, and experiences of, networked learning using computer-mediated conferencing (CMC). The data come from questionnaires administered at the start and end of four different courses, and their interpretation is informed by a set of interviews with students and teachers involved in these and other networked learning courses. Students’ views were generally positive at the start and at the end of each course, though they became more moderate over time. The structure of students’ reported feelings remained relatively stable over time. There was no evidence to suggest that male or younger students had more positive feelings about networked learning. The thoroughness with which CMC is integrated into a networked learning course appears as a significant factor in explaining differences in students’ feelings about the worth and value of their experience. As might be expected, a well-integrated course was associated with more positive experiences. 相似文献

We report the results of an experiment designed to elicit students’ subjective beliefs about the economic returns to college education. An important feature of our experimental design is the inclusion of financial incentives for accurate reporting. We also consider the extent to which individuals’ beliefs about their own returns differ from their beliefs about the returns for others. The evidence shows that students do have a self-enhancement tendency, and this finding cannot be attributed to previously uncontrolled order effects. The evidence also indicates that there is no significant difference between beliefs elicited using hypothetical surveys or real financial incentives in the elicitation procedure. This finding suggests that economists’ reluctance to gather subjective data on earnings expectations may not be warranted. 相似文献

The purpose of this article is to describe findings from a study of teachers’ social interaction during discussions about students’ thinking. The goal of the discussions was for the teachers to interpret their students’ thinking as revealed from work on non-routine, thought-revealing mathematical tasks, known as model-eliciting activities. The research reported in this article focuses on instances during the discussions when the teachers engaged in what the researcher termed ‘mini-inquiries’, occasions during which the teachers inquired into why their students thought about the associated model-eliciting activities as they did or when the teachers inquired into the underlying mathematical complexities associated with the model-eliciting activities. During these mini-inquiries, the teachers typically engaged in one of four types of interaction patterns that enabled them to meet some of the challenges of attending to students’ thinking that are described in United States reform documents. 相似文献

Village Elders’ and Secondary School Students’ Explanations of Natural Phenomena in Papua New Guinea
This research investigated the sources of explanations and understanding of natural phenomena in terms of the students’ cultural and school science experiences. The first phase involved interviews with eight village elders that probed their explanations and understanding of natural phenomena. The second phase involved the design, development and administration of two questionnaires on natural phenomena to 179 students in a rural boarding high school in Papua New Guinea (PNG). Most village elders gave explanations of many of the phenomena in terms of spirits, spells, magic, religion, and personal experiences. Most school-aged students choose scientific explanations of natural phenomena in terms of what they had learned in school or from personal experiences. However, many choose explanations of the same phenomena about spirits, spells and magic that came from the village, family or home. The study revealed that students’ ideas about natural phenomena are strongly governed and controlled by their school science knowledge in the school setting. It is likely that their own traditional knowledge cannot be identified in a school setting but that questionnaires in the students’ local language be given to students in their villages (as opposed to school). In addition, so as not to diminish the value of this traditional knowledge, science education programs are needed that are able to consider and harmonise traditional knowledge with school science. 相似文献

In 2004, the Department of Writing Studies at Roger Williams University in Bristol, Rhode Island, the U.S., began an assessment of student outcomes for two first-year writing courses (Fall 04 to Fall 05) to evaluate performance on previously established criteria. A study of the students’ Portfolio Assessment Sheets concluded that one pervasive problem was “Development” as determined partly by low A grades in the two courses. To engage the faculty (full-time and adjunct), the grades from Fall 04, Spring 05, and Fall 05 were presented during a Summer Workshop in June 2006. After analyzing a sample student essay, the 28 faculty participants discussed the implications of “Development” and evaluated the presentation itself. This case study of one college's participatory exercise in improving writing found some faculty resistance and some unintended results. 相似文献

Among the aims of education is the endeavor to bring students closer to an understanding of the world-at-large. Although pedagogical methods vary, educators would certainly agree that changing students’ knowledge and beliefs is among the end-goals of successful education (Murphy, 1998, Unpublished Doctoral Dissertation. University of Maryland, College of Education, College Park, MD). In the educational research literature, this “coming to know” has been referred to as conceptual change, and more recently there has been a resurgence of interest in “coming to believe” most often referred to as persuasion. Given that many researchers have defined belief as a form of knowledge, the delineating features of these two constructs are somewhat opaque. This present work closely examines these two constructs by identifying theoretical forbears of conceptual change and persuasion theory in the domains of philosophy and psychology with the intent of tracing their influence on educational research and practice. 相似文献

This paper analyzes how James Tobin’s widely cited concept of “intergenerational equity” for university endowments relates to the economic concepts of intertemporal substitutability and risk aversion. I show that Tobin’s concept of intergenerational equity is a very special case of intertemporal substitutability; a special case that implies very low tolerance for risk. Using the more general case, I show that the observed reduction in university spending rates during the 1990s can be viewed as a reasonable response to a period of non-recurring capital gains. 相似文献

This article aimed to examine the relationship between mirror neuron and theory of mind functions and to explore their possible roles in the emergence of an achievement goal contagion in educational settings such as classrooms. Based on the evidence from different lines of research such as neurobiology, neuropsychology, social psychology, and educational psychology, a multilevel model of achievement goal contagion was suggested in order to clarify the role of the goal contagion effect in achievement-related settings such as classrooms. In the model, it was assumed that the well-known effects of perceived classroom goal structures on students’ achievement goals were mediated by students’ theory of mind and mirroring abilities while the interaction between them was examined. Finally, it was concluded that the hypothesized model of achievement goal contagion may provide a solid neurobiological and psychological basis for the effects of perceived classroom goal structures on students’ achievement goals. Educational implications and directions for future research were also discussed. 相似文献

For decades traditional methods of testing have been criticized for saying relatively little reliably about students’ ability as well as causing anxiety, which can negatively affect students’ recall of learned information. The reform movement with its innovative approaches focusing on learner-centered education perceives assessment as an interactive feedback mechanism, which must provide for active, collaborative reflection by both teacher and students. This means that students must be active participants in designing assessment tasks and be given responsibility for using assessment data to monitor and improve their own learning (Valencia, 1990, p. 339). Focusing on alternative methods of assessment proposed by the opponents of traditional ones, the present study aimed at investigating the impact of cooperative test construction on Iranian EFL (English as a Foreign Language) students’ achievement as well as their attitudes towards such tests. The participants in this study were second- grade high school students (equivalent to Grade 11 in US senior high school) who were assigned to experimental and control groups based on their scores on a standardized retired version of Nelson test. Both groups received the same schedule of instruction for sixteen weeks. The students in the experimental group experienced cooperative test construction while the students in the control group did not have any role in the construction of their tests. The findings revealed statistically significant difference between grammatical knowledge of the students who cooperatively made their own test items and that of those who were tested traditionally. Furthermore, the students’ reactions to cooperative test construction were overwhelmingly positive. 相似文献
