美国《国家科学教育标准》倡导在课堂教学中实施形成性评价,形成性评价的一般模式,师生均需明确的问题:学生想达到什么目标?学生现在所处的是什么位置?如何能够达到目标?评价要遵循平等原则、有效性原则和可靠性原则。评价的重点要转向最被重视的内容、"活性"知识、科学理解力和推理能力、学生的进步和成绩及学习机会、学生自我评价以及教师参与外部评价。课堂评价还需要着力避免走进误区。 相似文献

Identifying exemplary science teachers through students’ perceptions of their learning environment 总被引：1，自引：0，他引：1
The purpose of this study was to examine students’ psychosocial perceptions of their science classroom learning environment in order to identify exemplary teachers. This mixed-method study used the valid and reliable What Is Happening In this Class? (WIHIC) questionnaire with over 3,000 middle school students in 150 classrooms in Australia. Exemplary teachers were defined as those whose students’ perceptions were more than one standard deviation above the mean for three of the five scales of Student Cohesiveness, Teacher Support, Involvement, Task Orientation and Equity. The reliability of the WIHIC scales ranged from 0.75 to 0.87. Eta2 showed that the WIHIC was able to distinguish between the perceptions of the students in the classroom. The construct validity of the WIHIC for identifying these exemplary teachers was confirmed through interviews with students and these views are reported in the article. 相似文献

Students’ perceptions of their classroom climate have been found to relate significantly to students’ learning outcomes. The purpose of the present study was to construct an instrument for assessing elementary-school students’ perceptions of classroom climate, based on a previous instrument that was being used in Chile by a public national school mental health program as a tool for aiding teachers in improving classroom management, but which showed poor psychometric properties. We used a six-staged mixed-methods approach to construct relevant items and dimensions based on this measure and by adapting previously-existing scales. Item development included participatory construction of items involving program officials, focus groups with students, and a pilot study. The final version was administered to a sample of 6813 elementary-school students. Results showed adequate reliability and construct validity, convergent validity with school climate, and divergent validity with peer victimisation. When consequential validity was explored through semi-structured interviews with program officials and school administrators, we found that the instrument was being used as a tool for helping teachers to improve their school climate and management skills. We discuss the importance of constructing instruments using a mixed-methods approach. 相似文献

Various item selection techniques are compared on resultant criterionreferenced reliability and validity. Techniques compared include three nominal criterion-referenced methods, a traditional point biserial selection, teacher selection, and random selection. Eighteen volunteer junior and senior high school teachers supplied behavioral objectives and item pools ranging from 26 to 40 items. Each teacher obtained reponses from four classes. Pairs of tests of various length were developed by each item selection method. Estimates of test reliability and validity were obtained using responses independent of the test construction sample. Resultant reliability and validity estimates were compared across item selection techniques. Two of the criterion-referenced item selection methods resulted in consistently higher observed validity. However, the small magnitude of improvement over teacher or random selection raises a question as to whether the benefit warrants the necessary extra effort on the part of the classroom teacher. 相似文献

The broad cognitive abilities defined by the Cattell–Horn–Carroll (CHC) theory have been shown to predict school achievement. However, the ecological validity of these constructs has not been studied in classroom settings. This study compares ratings by a sample of teachers (n = 53) and school psychologists (n = 86) of the importance of the CHC cognitive abilities in the classroom. The scale demonstrated adequate reliability (total scale α = .93, median α = .74), although evidence of construct validity varied between teachers and school psychologists. Both teachers and school psychologists rated quantitative ability, crystallized knowledge, and fluid reasoning as most important to school success. However, school psychologists rated short‐term memory and quantitative ability as more important than did the teachers. Importance of these differences for consultation is discussed. © 2009 Wiley Periodicals, Inc. 相似文献

Classroom communication often involves interactions between students and teachers from dissimilar cultures, which influence classroom learning because of their dissimilar communication styles influenced by their cultures. It is therefore important to study the influence of culture on classroom communication that influences the classroom verbal and nonverbal interactions. The purpose of this study was to develop and validate a new instrument to assess eight scales of students?? classroom communication learning environment: Body Language, Communication Rate, Communication Loudness, Eye Contact, English Usage, Verbal Support, Intra-gender Communication and Inter-gender Communication. The instrument was administered to 1,723 upper-secondary biology students in Brunei government schools. The alpha reliability (0.58?C0.91) and discrimination validity (0.08?C0.13) coefficients for these scales were within acceptable ranges. Statistically significant ??2 coefficients suggested that the instrument was able to differentiate between participating biology classes. Students perceived a low level verbal support and sometimes higher teacher communication rate in their classes. Dialects other than English, which is the medium of instruction, have been used in biology classes to some extent. There is a strong tendency for intra-gender than inter-gender communications in classes, which could limit the effectiveness of teaching and learning in constructivist classes 相似文献

This article suggests that a critical perspective of the notion of social representations can offer useful insights into understanding practices of teaching and learning in mathematics classrooms with immigrant students. Drawing on literature using social representations, previous empirical studies are revisited to examine three specific questions: what are the dominant social representations that permeate the mathematics classroom with immigrant students? What impact do these social representations have on classroom practices? What are the spaces for changing these practices through becoming reflective and critically aware of these representations? These questions are addressed mostly in relation to teachers’ representations, though the article also draws on data from research with students and parents to illustrate the diversity of representations and to argue for a critical and reflective perspective. 相似文献

In this paper, we support the validity of drawing from science studies to reshape science education. While true educational
reform must involve alternative curricular structures, we stress that we do not propose here either a comprehensive curricular
framework or a report on a pilot classroom project, as our research perspective comes from science studies rather than from
education. Instead this paper is intended to encourage educators to draw from methodologies used in science studies to further
their goals in education research and in classroom teaching. First, we examine theoretical connections and divergences between
science studies and theories of education. Secondly, we discuss the benefits of teaching science as a social process and offer
some suggestions that can be introduced by classroom teachers into pre-existing science curricula. 相似文献

Teachers' Grading Practices: Meaning and Values 总被引：3，自引：0，他引：3

Classroom teachers do not always follow recommended grading practices. Why not? It is possible to conceptualize this question as a validity issue and ask whether teachers' concerns over the many uses of grades outweigh concerns about the interpretation of grades. The purpose of this study was to investigate the meaning classroom teachers associate with grades, the value judgments they make when considering grades, and whether the meaning or values associated with grades differed by whether teachers had measurement instruction. A sample of 84 teachers, 40 with and 44 without measurement instruction, responded to classroom grading scenarios in two ways–with multiple-choice responses indicating what they would do and with written responses to the question, “Why did you make this choice?” A coding scheme based on Messick's (1989a, 1989b) progressive matrix of facets of validity was used for quantitative and qualitative analyses of written responses. The meaning of grades is closely related to the idea of student work; grades are pay students earn for activities they perform. The relationship of this notion to classroom management should be investigated. Teachers do make value judgments when assigning grades and are especially concerned about being fair. Teachers also are concerned about the consequences of grade use, especially for developing student self-esteem and good attitudes toward future school work. Measurement instruction made very little difference, although it did reduce the amount of self-referenced grading reported. 相似文献

The authors examined the ecological validity of using observation-based scores to evaluate individual teachers’ effectiveness, mirroring their use by school administrators. Using the Classroom Assessment Scoring System, the authors asked (a) how similar are teachers’ emotional support, classroom organization, and instructional support scores from each other; and (b) to what extent are these scores stable from day-to-day? Using a time-series, single-case methodology, the authors examined patterns of eight Kindergarten teachers’ performance in all lessons within a 4–5 week, thematically coherent science unit. Thus, the opportunity for identifying within-teacher stability was maximized. Teachers' instructional quality was significantly less effective than their emotional supportiveness and classroom organization. Furthermore, teachers’ effectiveness ratings varied markedly from one lesson to the next, for all three dimensions. 相似文献

Classroom management research is an important topic as teachers cannot effectively educate students in unstructured environments. With that said, few psychometrically sound measures are available to measure behavior and instructional management. Using 1520 Portuguese teachers, we evaluated the Behavior and Instructional Management Scale's (BIMS) psychometric properties using Bayesian estimation and found that the original 12-item scale provided reasonable evidence of factorial validity and internal consistency reliability; however, a slightly revised model may be more promising. The BIMS subscales also had strong concurrent validity evidence based on the associations with perceived student engagement, perceived instructional strategies, and perceived classroom management. 相似文献

This study investigated firstly the reliability and validity of an Indonesian version of the Questionnaire on Teacher Interaction (QTI). Second, perceptions of Indonesian secondary school teachers?? interpersonal behaviour as perceived by students and teachers were studied with the QTI. Third, differences between students?? and teachers?? perceptions regarding interpersonal teacher behaviour were compared. The QTI itself is based on the Model of Interpersonal Behaviour which maps teacher behaviour in terms of Influence (Dominance?CSubmission) and Proximity (Cooperation?COpposition). In this study, an Indonesian version of the QTI was constructed and distributed to 2,380 students of 69 teachers from 85 classes (grade 7?C9) from 12 public lower secondary schools in Indonesia. The results showed high reliability and validity for the instrument. Students?? and teachers?? average ratings on Influence were similar, while teacher??s ratings of Proximity were higher than those of students. 相似文献

This article reports the development, validation and use of an instrument designed to provide teachers with feedback information,
based on students’ perceptions, about their classroom environments. The instrument was developed to provide teachers with
feedback that they could use to reflect on their teaching practices and, in turn, guide the implementation of strategies to
improve their learning environments. To determine the validity and reliability of the new instrument, data from 2043 grade
11 and 12 students from 147 classes in 9 schools were analysed. The Rasch model was used to convert data collected using a
frequency response scale into interval data that are suitable for parametric analyses. During an action research process,
reflective journals, written feedback, discussions at a forum and interviews with eight teachers helped to illuminate the
processes used by teachers during action research. This article reports the views of these teachers in general and examines
more closely how one of the teachers used student responses to the learning environment questionnaire as a tool for reflection
and as a guide in transforming her classroom environment. This case study helped us to gauge the extent to which action research
based on students’ perceptions of the learning environment was useful in guiding teachers’ improvements of their classroom
learning environments. 相似文献

The extent to which teachers understand the concept of self-regulation skills and how best to implement practices that enhance self-regulation in children in the early childhood education classroom remains unexamined. The purpose of this study is to examine the psychometric properties of the self-reporting Early Childhood Educators Knowledge of Self-Regulation Questionnaire (ECESRQ) instrument designed to identify teachers’ knowledge and instruction of self-regulation skills in the classroom. Exploratory factor analysis (EFA) was used to determine three latent factors: teacher attitudes and beliefs, classroom management techniques, and child behavior. The findings identified parallel the literature in the preservice teacher-training arena, suggesting a theoretical basis for the underlying constructs. EFA contributed to establishing good estimates of construct validity in the ECESRQ; in addition Cronbach’s alpha results demonstrated moderate levels of internal reliability. Pearson correlation was used to additionally determine the extent to which teachers understand self-regulatory skills and their ability to implement effective tools in the classroom to enhance these skills. Results and implications for practice in the early childhood classroom are discussed. 相似文献

Monitoring the quality of teaching practices of primary school teachers in low-and-middle-income countries is often hampered by the lack of freely available classroom observation tools that are feasible to administer, validated in their own setting, and can be used as part of national monitoring systems. To address this discrepancy, Teach, an open-access classroom observation tool, was developed to measure the quality of teaching practices of primary school teachers in low-and-middle-income countries. This paper uses data from Punjab, Pakistan to evaluate the validity of Teach. Results show that Teach scores were internally consistent, presented good inter-rater reliability, and provided sufficient information to differentiate low from high-quality teaching practices. Further, higher Teach scores were associated with higher student outcomes. 相似文献
