A perennial challenge for urban education in the United States is finding effective ways to address the academic achievement gap between African American and White students. There is widespread and justified concern about the persistence of this achievement gap. In fact, historical evidence suggests that this achievement gap has existed at various times for groups other than African Americans. What conditions prevailed when this achievement gap existed for these other groups? Conversely, under what conditions did the gap diminish and eventually disappear for these groups? This article explores how sociocultural factors involved in the manifestation and eventual disappearance of the gap for these groups may shed some light on how to address the achievement gap for African American students in urban science classrooms. Our conclusion is that the sociocultural position of groups is crucial to understanding and interpreting the scholastic performance of students from various backgrounds. We argue for a research framework and the exploration of research questions incorporating insights from Ogbu's cultural, ecological theory, as well as goal theory, and identity theory. We present these as theories that essentially focus on student responses to societal disparities. Our ultimate goal is to define the problem more clearly and contribute to the development of research‐based classroom practices that will be effective in reducing and eventually eliminating the achievement gap. We identify the many gaps in society and the schools that need to be addressed in order to find effective solutions to the problem of the achievement gap. Finally, we propose that by understanding the genesis of the gap and developing strategies to harness the students' responses to societal disparities, learning can be maximized and the achievement gap can be significantly reduced, if not eliminated entirely, in urban science classrooms. © 2001 John Wiley & Sons, Inc.

This article reports the validity and use of a new form of the Constructivist Learning Environment Survey (CLES). As part of a larger study, a comparative student version (CLES-CS) was developed to evaluate the impact of an innovative teacher development program (based on the Integrated Science Learning Environment, ISLE, model) in school classrooms. Two separate response blocks for 30 items comprising five scales are presented in side-by-side columns to measure students’ perceptions on a five-point frequency response scale of the extent to which certain psychosocial factors are prevalent in the science class taught by a teacher who had attended the ISLE program (THIS), as well as their perceptions of other science and non-science classes taught by other teachers in the same school (OTHER). The five scales of the CLES are called Personal Relevance, Uncertainty of Science, Shared Control, Critical Voice, and Student Negotiation. Using data collected from 1079 students in 59 classes in north Texas, principal components factor analysis with varimax rotation and Kaiser normalization confirmed the
a priori structure of the CLES-CS. The factor structure, internal consistency reliability, discriminant validity, and the ability to distinguish between different classes and groups were supported for the CLES-CS. Students whose science teachers had attended the ISLE program (THIS) perceived higher levels of Personal Relevance and Uncertainty of Science in their classrooms relative to the classrooms of other science and non-science teachers in the same schools (OTHER). Similar results were found when comparing the classroom environment perceptions of students whose science teachers had attended the ISLE program with the perceptions of students whose science teacher had attended alternative field trip programs (non-ISLE). 相似文献

No previous research has employed learning environments criteria in evaluating the effectiveness of the system of teacher certification sponsored by the National Board for Professional Teaching Standards. Because the litmus test of any professional development effort is the extent of the changes in teaching behaviours in participating teachers’ classrooms, our study drew on the field of learning environments in evaluating the effectiveness of National Board Certified (NBC) teachers in terms of their students’ perceptions of their classroom environments. A sample of 443 students in 21 Grade 8 and 10 science classes taught by NBC teachers in South Florida was compared with a matched group of 484 students in 17 classes taught by non-NBC teachers in terms of classroom environment (as assessed by the What Is Happening In this Class?) and students’ attitudes and achievement. Statistically significant differences (with small to medium effect sizes ranging from 0.14 to 0.35 standard deviations) were found in favour of NBC teachers for numerous classroom and environment scales (Teacher Support, Involvement, Task Orientation, Investigation and Cooperation) and for student attitudes. 相似文献

This study compares the effects of two methods of teaching—teacher-centered and cooperative learning—on students’ science
achievement and use of social skills. The sample consists of 163 female elementary science students in 8 intact grade 5 classes
who were assigned to 2 instructional methods and were taught an identical science unit by 4 classroom teachers. The students’
science achievement was measured by a researcher-designed achievement test given to students as a pretest and a posttest.
Students’ social skills were determined by a researcher-designed survey administered as a pretest and posttest. Analysis of
the achievement test scores and the social skills survey responses revealed that cooperative learning strategies have significantly
(p > 0.05) more positive effects on both students’ achievement and social skills than teacher-centered strategies. These results
provide an evidential base to inform policy decisions and encourage and persuade teachers to implement cooperative learning
methods in Kuwaiti classrooms. 相似文献

The current reform movement in science education promotes standards‐based teaching, including the use of inquiry, problem solving, and open‐ended questioning, to improve student achievement. This study examines the influence of standards‐based teaching practices on the achievement of urban, African‐American, middle school science students. Science classes of teachers who had participated in the professional development (n = 8) of Ohio's statewide systemic initiative (SSI) were matched with classes of teachers (n = 10) who had not participated. Data were gathered using group‐administered questionnaires and achievement tests that were specifically designed for Ohio's SSI. Analyses indicate that teachers who frequently used standards‐based teaching practices positively influenced urban, African‐American students' science achievement and attitudes, especially for boys. Additionally, teachers' involvement in the SSI's professional development was positively related to the reported use of standards‐based teaching practices in the classroom. The findings support the efficacy of high‐quality professional development to change teaching practices and to enhance student learning. © 2000 John Wiley & Sons, Inc.

This study explored learning competency based on the Indonesian National Examination focusing especially on chemistry performance and the circumstances of senior high school students and teachers in rural areas of Simeulue Island, Indonesia. The National Examination total score and chemistry score for students in rural areas were consistently lower than students in urban areas during 2008–2010. The majority of rural students were failing to master key chemistry concepts. Their low performance on laboratory-based questions appeared to indicate that the associated practical work was not done as part of the chemistry courses. Some chemistry topics were not taught due to insufficient time, student weaknesses, insufficient textbooks, and other reasons. The issues of low competency of teachers, poverty for the majority of students, low enrollment in schools, and low competition among students in these rural senior high schools appeared to be common problems across rural settings. The local government has recommended providing a consolidated rural high school with qualified chemistry teachers, laboratories, and transportation to address factors negatively influencing student achievement. Furthermore, local rural school officials need to recruit and retain qualified teachers in these isolated areas, provide effective textbooks and instructional resources, and facilitate the professional development of chemistry teachers. 相似文献

I use unusually detailed data on schools, teachers and classrooms to explain student achievement growth in rural Guatemala. Several variables that have received little attention in previous studies – including the number of school days, teacher content knowledge and pedagogical methods – are robust predictors of achievement. A series of decompositions by student ethnicity and type of school shed some additional light on important questions in the Guatemalan context, and beyond. The large indigenous test score gap is not explained by differences in an extensive list of observable features of schools. The large effect for community characteristics suggests peer group effects or more general institutional differences related to services or labor markets. PRONADE community schools are associated with moderate gains vis-à-vis public schools in areas related to utilization of capacity, such as days worked. But these gains are largely offset by lower teacher capacity, which highlights the challenge of improving school quality in poor, rural areas. 相似文献

The science achievement of 226 5th graders from districts that have a kit-based inquiry science curriculum supported by intensive
professional development (PD) is compared with data from a group of 173 5th graders from other districts that use nonkit science
materials and do not have systematic science PD for teachers. Within the kit-based project, the sample of project teachers
is stratified to select teachers with a high number of science PD hours versus those with few hours. While there were no significant
differences in the mean total scores for kit-based students with low PD versus high PD teachers, the kit-based classrooms
scored significantly higher than students in nonkit classrooms on both the pretest and posttest, though there were significantly
more minutes of science instruction in the nonkit classrooms. Finally, nonkit teachers taught more units of shorter length
and reported lower levels of preparedness to use reform pedagogical approaches. 相似文献

Abstract The accuracy of achievement test score inferences largely depends on the sensitivity of scores to instruction focused on tested objectives. Sensitivity requirements are particularly challenging for standards-based assessments because a variety of plausible instructional differences across classrooms must be detected. For this study, we developed a new method for capturing the alignment between how teachers bring standards to life in their classrooms and how the standards are defined on a test. Teachers were asked to report the degree to which they emphasized the state's academic standards, and to describe how they taught certain objectives from the standards. Two curriculum experts judged the alignment between how teachers brought the objectives to life in their classrooms and how the objectives were operationalized on the state test. Emphasis alone did not account for achievement differences among classrooms. The best predictors of classroom achievement were the match between how the standards were taught and tested, and the interaction between emphasis and match, indicating that test scores were sensitive to instruction of the standards, but in a narrow sense. 相似文献

Since 1999, Slovenia has been in the process of introducing nine years of compulsory education to replace the previous eight-year system of compulsory education. Under the new system, the school entry age is six years rather than the former seven years. This reform of the system necessitated a number of other changes, such as those relating to the curriculum and teaching approaches. The purpose of this study was to compare the “new” Slovenian science curriculum with the “old” to ascertain if different relationships exist between the two in terms of achievement and gender, attitudes toward science, and the amount of experimental work undertaken by students in school. Data from the IEA TIMSS 2003 study were used to analyze these relationships. The analyses employed basic statistics and log-linear modeling of the effects of gender, school system, amount of experimental work in school, and students’ science achievement. Compared to students taught under the old curriculum, students taught under the new curriculum performed slightly better on the overall science test. A large decrease in gender differences in achievement was also apparent. The relationship between experimental work and achievement strengthened. Conducting experiments at every lesson related to lower student achievement, while conducting experiments during half of the science lessons related to higher achievement. These findings have a clear message for teachers and policymakers. A moderate amount of time devoted to student experimental work seems to raise science achievement of students as well as promote more positive attitudes toward learning science. 相似文献

This paper investigates empirically whether immigrant students in Switzerland perform poorly compared to their native counterparts and provides some explanations. Using a national sample of the 2000 PISA (Programme for International Student Assessment) database, we first analyze the impact of immigrant status on pupils’ achievement. We find a negative and significant impact of immigrant status on test scores in reading, mathematics and science literacy, even after controlling for a set of characteristics. We then decompose the observed reading score gap between Swiss and immigrant students to identify whether gaps in endowments explain test score differences along the distribution. Lower endowments explain most of the achievement gap in reading between Swiss and second-generation immigrants. However, lower returns explain around one quarter of the achievement gap between Swiss and first-generation immigrants for the weakest pupils. 相似文献

In this paper I describe and discuss the way that a book I had written on a five-year longitudinal study of school science teaching was received by the pupils and teachers it featured. By and large the pupils’ reception was positive. However, one group of teachers was deeply hurt by the book. I trace this mainly to my failure to consider adequately their fears of the consequences of the book’s publication and possibly to my failure to consider with them the psychological significance of my withdrawing from the school after five years of regular study. I hope that there are lessons not only for myself but also for others considering longitudinal and ethnographic research in science education and more broadly. 相似文献

The effect of inquiry‐based learning on the achievement goal‐orientation of grade 10 physical sciences learners at township schools in South Africa 
下载免费PDF全文
下载免费PDF全文 Due to apartheid policies, Black African learners in South Africa have been severely disadvantaged in school science. Despite policy changes to redress these historical imbalances, Black African learners continue to underperform in science. Previous research has identified motivation as a key factor that impacts performance. Achievement goal orientation is a construct of motivation that explains learning behaviour. In an attempt to address the problem of learner motivation, this study investigated the effect of inquiry‐based learning on the achievement goal‐orientation of grade 10 physical sciences learners at historically disadvantaged township schools in South Africa. In South Africa, the term “township” usually refers to under‐developed urban areas that were historically created for “non‐whites” during the apartheid era. The findings showed that the experiment group of learners who experienced inquiry‐based learning significantly gained in mastery goal orientation, while the control that were taught through a traditional direct didactic approach had an insignificant change in their mastery goal orientation. From these results, it can be concluded that inquiry‐based learning does support a mastery goal orientation in learners. This orientation is regarded as desirable because mastery approach goals could support positive outcomes in conceptual learning, leading to an improvement in science achievement of learners. 相似文献

This article explores pre-service and in-service science teachers’ perceptions on active learning, and examines the effectiveness of active learning by pre-service science teachers in the Irish second level classroom through a two-phase study. In the first phase, data on perceptions were gathered from final year pre-service teachers and in-service teachers in Irish post-primary schools. In the second phase, pre-service science teachers, working with teacher educators, designed a comparative test for students in lower secondary science classrooms. This tested achievement differences for students taught in traditional ways and students taught using active learning approaches. While the test results show a significant difference between traditional teaching and active learning, overall analysis indicates that the majority of teachers in the study were not convinced of the value of this way of teaching. The findings have implications for science teaching and the enactment of curriculum reform measures in compulsory education. 相似文献

When evaluating equity, researchers often look at the “achievement gap.” Privileging knowledge and skills as primary outcomes of science education misses other, more subtle, but critical, outcomes indexing inequitable science education. In this comparative ethnography, we examined what it meant to “be scientific” in two fourth‐grade classes taught by teachers similarly committed to reform‐based science (RBS) practices in the service of equity. In both classrooms, students developed similar levels of scientific understanding and expressed positive attitudes about learning science. However, in one classroom, a group of African American and Latina girls expressed outright disaffiliation with promoted meanings of “smart science person” (“They are the science people. We aren't like them”), despite the fact that most of them knew the science equally well or, in one case, better than, their classmates. To make sense of these findings, we examine the normative practice of “sharing scientific ideas” in each classroom, a comparison that provided a robust account of the differently accessible meanings of scientific knowledge, scientific investigation, and scientific person in each setting. The findings illustrate that research with equity aims demands attention to culture (everyday classroom practices that promote particular meanings of “science”) and normative identities (culturally produced meanings of “science person” and the accessibility of those meanings). The study: (1) encourages researchers to question taken‐for‐granted assumptions and complexities of RBS and (2) demonstrates to practitioners that enacting what might look like RBS and producing students who know and can do science are but pieces of what it takes to achieve equitable science education. © 2011 Wiley Periodicals, Inc., Inc.

Comparative research in multilingual urban primary schools indicates that the pedagogical and political goals of schooling may operate at cross-purposes. Classroom observations and teacher interview-discussions were conducted in classes for immigrant children in Montreal, Quebec, Canada, where the language of instruction is French, and in classes in Pretoria, Gauteng Province, South Africa, where children from many different language backgrounds are taught in English. Two main themes emerged: (1) pedagogically, effective teacher–learner communication can break down when teachers are unaware of the roles that language and culture play in second language classrooms; (2) politically, efforts to assimilate learners into new socio-cultural/political contexts sometimes take precedence over sound pedagogical practice, such as drawing on the linguistic and cultural repertoire that learners bring to the classroom. This ongoing qualitative research underlines the importance of preparing pre-service and in-service teachers for the linguistic and cultural diversity they are bound to encounter in their classrooms, and of deepening their understanding of the influence of such diversity on the teaching–learning process. 相似文献

This study explores teachers’ observable value orientations in literature and history classrooms, wishing to investigate how teachers infuse their values into instructional settings through their conceptions of the taught subject, the process of making meaning, and their involvement in the process of value communication.Through consideration of observation, interview and additional data, the common features underlying teachers’ value orientations are identified. One may conclude that although participants avoid the clear involvement in value communication, they search for a balance in defending the humanistic tradition and enacting a more critical and multi-perspective development of students’ sense about values. The taught subject seems to affect the displayed value orientations. 相似文献

While it is generally acknowledged that increased use of formative assessment (or assessment for learning) leads to higher quality learning, it is often claimed that the pressure in schools to improve the results achieved by students in externally‐set tests and examinations precludes its use. This paper reports on the achievement of secondary school students who worked in classrooms where teachers made time to develop formative assessment strategies. A total of 24 teachers (2 science and 2 mathematics teachers, in each of six schools in two LEAs) were supported over a six‐month period in exploring and planning their approach to formative assessment, and then, beginning in September 1999, the teachers put these plans into action with selected classes. In order to compute effect sizes, a measure of prior attainment and at least one comparison group was established for each class (typically either an equivalent class taught in the previous year by the same teacher, or a parallel class taught by another teacher). The mean effect size in favour of the intervention was 0.32. 相似文献

This study examines teachers’ perceptions of classroom motivation and achievement among students displaying culture-based classroom behaviors. Sixty-two elementary school teachers read scenarios of hypothetical students who behaviorally manifested themes purported to be consistent with a European/mainstream cultural ethos (competition, individualism) or Afrocultural ethos (communalism, verve). Teachers then rated students’ motivation and achievement as if they were in their classrooms. Motivation and achievement ratings were significantly higher for students displaying competitive and individualistic classroom behaviors than communal or vervistic behaviors. These findings suggest that the value teachers assign to academic success should not be understood in the absence of cultural considerations. 相似文献
