This study examined the effect of fidelity of implementation (FOI) on the science achievement gains of third grade students broadly and students with limited literacy in English specifically. The study was conducted in the context of a professional development intervention with elementary school teachers to promote science achievement of ELL students in urban schools. As the criterion for measuring FOI, we focused on the quality of instructional delivery in teaching science to ELL students. We measured FOI using both teachers' self‐reports and classroom observations during the first year of the intervention. Science achievement was measured by a pretest and posttest over the school year. The results indicate that none of the measures of FOI using teachers' self‐reports or classroom observations had significant effects on science achievement gains. The results are discussed in terms of issues about conceptualization and measurement of FOI in educational interventions. © 2009 Wiley Periodicals, Inc. J Res Sci Teach 46: 836–859, 2009  相似文献

Reform‐based curriculum materials have been suggested as a mechanism to make inquiry‐based instruction more prevalent in secondary science classrooms, specifically when accompanied by comprehensive professional development (Loucks‐Horsley, Hewson, Love, & Stiles, 1998 ; Powell & Anderson, 2002 ). This research examines the implementation of a reform‐based high school chemistry curriculum in a large, urban school district. We explicitly consider the role of the teachers' knowledge and beliefs in their implementation of the reform‐based chemistry curriculum, as well as school level factors. Qualitative and quantitative data were collected in the form of beliefs interviews and classroom observations from 27 high school chemistry teachers. Analysis of the data revealed that implementation of the curriculum was strongly influenced by the teachers' beliefs about teaching and learning, and the presence of a supportive network at their school sites. © 2007 Wiley Periodicals, Inc.

Evidence of a gap in student understanding has been well documented in chemistry: the typical student holds an abundance of misconceptions. The current expectation is that educational reform will foster greater student achievement via inquiry teaching within classrooms. Using assessments involving both conceptual and algorithmic knowledge of gas behaviour, gas laws, and phase changes in chemistry, this study aims to determine the relationship between inquiry teaching and student achievement. The topics were tested in the context of a unit from a reform‐based curriculum that features inquiry, hands‐on activities, and cooperative learning. This curriculum provides step‐by‐step guidance for each lesson in the teacher materials, in order to promote quality inquiry teaching. Two schools were involved in this study, with two high school chemistry teachers from each school. Each teacher participated in professional development and implemented this curriculum with sufficient training and guidance to develop reform methods. Student achievement was found to positively correlate with the use of inquiry teaching about the assessed concepts, regardless of teacher experience or school context.  相似文献

The purpose of this study was to examine the extent to which public school teachers implemented evidence‐based interventions for students with autism in the way these practices were designed. Evidence‐based practices for students with autism are rarely incorporated into community settings, and little is known about the quality of implementation. An indicator of intervention quality is procedural implementation fidelity (the degree to which a treatment is implemented as prescribed). Procedural fidelity likely affects student outcomes. This project examined procedural implementation fidelity of three evidence‐based practices used in a randomized trial of a comprehensive program for students with autism in partnership with a large, urban school district. Results indicate that teachers in public school special education classrooms can learn to implement evidence‐based strategies; however, they require extensive training, coaching, and time to reach and maintain moderate procedural implementation fidelity. Procedural fidelity over time and across intervention strategies is examined.  相似文献

Findings from two studies are discussed in relation to the experiences and challenges faced by teachers trying to implement effective group work in schools and classrooms and to reflect on the lessons learnt about how to involve pupils with special educational needs (SEN). The first study reports on UK primary school teachers' experiences of implementing a year-long intervention designed to improve the effectiveness of pupils' collaborative group-working in classrooms (the SPRinG [Social Pedagogic Research into Group-work] project). The second study (the MAST [Making a Statement] project) involved systematic observations of 48 pupils with SEN (and comparison pupils) and case studies undertaken in the context of primary school classrooms.  相似文献

The present study investigated the effectiveness of a novel class‐wide intervention, the Classroom Password, for increasing the academic engaged behavior of middle school students. The effectiveness of an independent group contingency was evaluated using a concurrent multiple baseline design across three seventh‐ and eighth‐grade classrooms. Results indicated that the intervention was effective across all three classrooms in increasing students’ academic engagement, or on‐task behavior, as evidenced by visual analysis and moderate to large effect sizes. Decreases in disruptive behavior were also observed across all three classrooms. Off‐task behavior was not substantially affected in any of the three classrooms. The intervention received mixed ratings by the classroom teachers regarding its social validity. Results of the present study suggest that the Classroom Password may be an effective class‐wide intervention for increasing the academically engaged behavior and decreasing the disruptive behavior of middle school students during instructional time.  相似文献

To be an effective urban educator requires teachers to understand the contextual factors of students, the school, and the community, and their cumulative effects on learning. Urban teacher academies support a better understanding of urban classrooms and challenge stereotypes of the urban context. The focus of this study was to compare participants' perceptions of urban settings before and after 2 weeks spent at an urban teacher academy for high school students.  相似文献

The Biology Workbench (BW) is a web‐based tool enabling scientists to search a wide array of protein and nucleic acid sequence databases with integrated access to a variety of analysis and modeling tools. The present study examined the development of this scientific tool and its consequent adoption into the context of high school science teaching in the form of the Biology Student Workbench (BSW). Participants included scientists, programmers, science educators, and science teachers who played key roles along the pathway of the design and development of BW, and/or the adaptation and implementation of BSW in high school science classrooms. Participants also included four teachers who, with their students, continue to use BSW. Data sources included interviews, classroom observations, and relevant artifacts. Contrary to what often is advocated as a major benefit accruing from the integration of authentic scientific tools into precollege science teaching, classroom enactments of BSW lacked elements of inquiry and were teacher‐centered with prescribed convergent activities. Students mostly were preoccupied with following instructions and a focus on science content. The desired and actual realizations of BSW fell on two extremes that reflected the disparity between scientists' and educators' views on science, inquiry science teaching, and the related roles of technological tools. Research on large‐scale adoptions of technological tools into precollege science classrooms needs to expand beyond its current focus on teacher knowledge, skills, beliefs, and practices to examine the role of the scientists, researchers, and teacher educators who often are involved in such adoptions. © 2010 Wiley Periodicals, Inc.

This study examined issues in supporting middle-school teachers to become more learner centered when implementing computer-based, workplace simulations in their classrooms. Specifically, this report focuses on a participant observation study of two teachers to develop and evolve a framework for professional development. The framework was developed based on prior professional development efforts, information on developing learner-centered classrooms, and data about teacher change. The framework included five key pieces: (a) reflection, (b) proximal goals, (c) collegial support groups, (d) one-on-one feedback, and (e) support materials for the teachers. The foundation for the framework was a belief that change is individual and needs to be supported in context and over time. The data included field observations as the teachers used the simulations in their classrooms made by the author and three outside observers, and interviews with each teacher following her use of the simulation program. During the four-month study, the original framework evolved in response to the data collected. The final version of the framework focuses on the professional developer working with teachers to develop reflective skills. Proximal goals became a focusing tool for reflection after teachers had begun to develop their reflective skills. The interplay between reflection and proximal goals was enhanced by outside resources, one-on-one feedback, and collegial group meetings. The work reported here was comp;eted as part of a dissertation conducted at Indiana University’s Center for Innovation in Assessment, and was supported in part by grants from the Andrew W. Mellon Foundation and the Russell Sage Fundation. The school and participant names have been changed to protect their identity. All researcher names are actual.  相似文献

Education in the United Arab Emirates (UAE) faces major problems which may hinder its future development. These include low achievement in science and a negative attitude toward science subjects, which have resulted in a high number of student dropouts from the science track in high school. It is believed among UAE educators that the main reason is the way science that has been taught in its schools. A solution to this problem depends on finding effective teaching methods, which maintain student achievement, improve students' attitude and provide opportunities to develop essential scientific skills. The effectiveness of Student Team-Achievement Division (STAD) for teaching science to high school classes in the UAE was investigated. The sample was selected randomly. A representative group of UAE high school students was chosen from the northern province, which includes urban areas, and from the eastern province, which includes rural areas. The study involved sixteen tenth grade classes. During the second semester of the academic year 1998/1999, three units in the chemistry curriculum were covered. This study was designed to investigate the effectiveness of STAD in teaching high school chemistry in the UAE and to find out which groups, gender, area, and ability benefitted most.  相似文献

The Learning Environment Inventory (LEI), adapted to conditions in Israeli schools and factor analysed on an Israeli sample, was administered to 572 students in 10th‐grade biology classes. Fourteen classes were in urban schools, six in Kibbutz district schools. All classes used the same BSCS (yellow version) curriculum. Seven out of the nine scales of the LEI Israeli version yielded significantly different scores for urban and Kibbutz samples indicating a more positive social learning climate in the Kibbutz than in the city. Differences were most marked on scales assessing cohesiveness, favouritism and cliquishness. Results were interpreted to indicate that social climate in classrooms is influenced by school‐wide policies regarding relationships in school, and not only by within‐class factors such as curriculum and teaching method.  相似文献

We investigated differences between field-study classrooms and traditional science classrooms in terms of the learning environment and students’ attitudes to science, as well as the differential effectiveness of field-study classrooms for students differing in sex and English proficiency. A modified version of selected scales from the What Is Happening In this Class? questionnaire was used to assess the learning environment, whereas students’ attitudes were assessed with a shortened version of a scale from the Test of Science Related Attitudes. A sample of 765 grade 5 students from 17 schools responded to the learning environment and attitude scales in terms of both their traditional science classrooms and classrooms at a field-study centre in Florida. Large effect sizes supported the effectiveness of the field-studies classroom in terms of both the learning environment and student attitudes. Relative to the home school science class, the field-study class was considerably more effective for students with limited English proficiency than for native English speakers.  相似文献

Research-based digital games hold great potential to be effective tools in supporting next-generation science learning. However, as with all instructional materials, teachers significantly influence their implementation and contribute to their effectiveness. To more fully understand the contributions and challenges of teacher implementation of digital games, we studied the replacement of existing high school biology genetics lessons over a 3- to 6-week period with Geniverse, an immersive, game-like learning environment designed to be used in classrooms. The Geniverse materials infuse virtual experimentation in genetics with a narrative of a quest to heal a genetic disease; incorporate the topics of meiosis and protein synthesis with inheritance; and include the science practices of explanation and argumentation. The research design involved a quasi-experiment with 48 high school teachers and about 2000 students, student science content knowledge and argumentation outcome measures, and analysis using hierarchical linear modeling. Results indicate that when Geniverse was implemented as the designers intended, student learning of genetics content was significantly greater than in the comparison, business-as-usual group. However, a wide range of levels of Geniverse implementation resulted in no significant difference between the groups as a whole. Students’ abilities to engage in scientific explanation and argumentation were greater in the Geniverse group, but these differences were not statistically significant. Observation, survey, and interview data indicate a range of barriers to implementation and teacher instructional decisions that may have influenced student outcomes. Implications for the role of the teacher in the implementation of game-based instructional materials are discussed.  相似文献

In this paper, we examine how students discuss and interpret data and whether these actions vary depending on the type of data they analyse. More specifically, we are interested in whether students perform differently when analysing first‐hand data, which they collect themselves, compared with second‐hand data provided to them. Our data analysis focused on two classrooms using two different curriculum units, chemistry in Grade 7 and biology in Grade 8, collected during the 2002/03 school year from a Mid‐western urban middle school in the USA. We analysed classroom videotape associated with lessons in which students discussed first‐hand and second‐hand data both in small group settings and full class discussions. We found the two types of data offer different benefits and limitations, suggesting that both types of data are important for students to work with as they develop skills in scientific inquiry practices. We discuss the characteristics of classroom discussions around different data sources as well as implications for the design of curriculum materials, instructional environments, and student learning in science.  相似文献

This article describes the results of a second school improvement study directed at schools with mixed‐age classes, and compares the results of this second study with the first study. The second improvement study examines the effects of a staff development programme which introduced selected findings from teaching effectiveness research into ongoing school settings with mixed‐age classes. In addition to the staff development programme the effects of coaching are also evaluated. In contrast to the first improvement study the staff development programme was implemented by teacher educators and school counsellors in the regular educational support context (in‐service teacher education). A quasi‐experimental, treatment‐control group investigation was designed to test the effects of the staff development programme ‘Dealing with mixed‐age classes’, and the effects of coaching. Based on pre‐ and post‐training classroom observations, the second improvement study‐‐like the first one‐‐revealed a significant treatment effect for pupils’ time‐on‐task levels in mixed‐age classrooms, and for teachers’ instructional and classroom management skills. Only two coaching effects were found: for organising effective instruction and for dealing with disturbances. Time‐on‐task levels improved more strongly in classes of coached teachers. In the second improvement study the effects on teacher instructional and classroom management skills, and pupil behaviour are smaller than in the first study. The staff development programme as conducted in regular in‐service settings by teacher educators and school counsellors was less effective than the staff development programme as conducted in an evaluation setting by the designers of the programme.  相似文献

Many state and federal governments have mandated in such documents as the National Science Education Standards that inquiry strategies should be the focus of the teaching of science within school classrooms. The difficult part for success is changing teacher practices from perceived traditional ways of teaching to more inquiry‐based approaches. Arguments are often made about the effectiveness of these traditional strategies. The purpose of this study was to compare the effectiveness of the inquiry‐based approach known as the Science Writing Heuristic approach as a treatment to traditional teaching practices on students' post‐test scores in relation to students' achievement level and teacher's implementation of the approach. A mixed‐method research approach was used to analyze the teacher observational data and students' test results. The major findings of this study are that the quality of the implementation does have an impact on student performance on post‐test scores and that high‐quality implementation of the Science Writing Heuristic approach has significant advantages in closing the achievement gap within science classrooms.  相似文献

What are the barriers to technology‐rich inquiry pedagogy in urban science classrooms, and what kinds of programs and support structures allow these barriers to be overcome? Research on the pedagogical practices within urban classrooms suggests that as a result of many constraints, many urban teachers' practices emphasize directive, controlling teaching, that is, the “pedagogy of poverty” (Haberman, 1991 ), rather than the facilitation of students' ownership and control over their learning, as advocated in inquiry science. On balance, research programs that advocate standards‐based or inquiry teaching pedagogies demonstrate strong learning outcomes by urban students. This study tracked classroom research on a technology‐rich inquiry weather program with six urban science teachers. The teachers implemented this program in coordination with a district‐wide middle school science reform. Results indicated that despite many challenges in the first year of implementation, students in all 19 classrooms of this program demonstrated significant content and inquiry gains. In addition, case study data comprised of twice‐weekly classroom observations and interviews with the six teachers suggest support structures that were both conducive and challenging to inquiry pedagogy. Our work has extended previous studies on urban science pedagogy and practices as it has begun to articulate what role the technological component plays either in contributing to the challenges we experienced or in helping urban science classrooms to realize inquiry science and other positive learning values. Although these data outline results after only the first year of systemic reform, we suggest that they begin to build evidence for the role of technology‐rich inquiry programs in combating the pedagogy of poverty in urban science classrooms. © 2002 John Wiley & Sons, Inc.

This quantitative study investigated the differences in perceptions and attitudes toward technology integration of K-12 public school teachers in rural, suburban, and urban environments. The purpose was to examine the relationship between frequency of use and perception of effectiveness of web-based learning tools based upon the type of school setting. A survey of 2,200 school teachers in a Mid-Atlantic state revealed significant differences of usage and perceived effectiveness among respondents. The research found teachers from urban schools trailed rural and suburban schools in usage and perception. Suburban schools indicated the highest perceptions of technology effectiveness, followed by their rural peers. Current teachers, administrators, and teacher educators may benefit from this insight to identify the most effective technologies, as well as work focus on improved use of technology, particularly in the urban classroom.  相似文献

Evaluating multigrade school reform in Latin America   总被引:1,自引:0,他引:1  
This paper describes three multigrade school reforms in Latin America: (1) Colombia’s Escuela Nueva, (2) Guatemala’s Nueva Escuela Unitaria, and (3) Chile’s MECE‐Rural. Each reform endowed primary teachers and students with special training and instructional materials, and encouraged new kinds of instruction in rural classrooms, with the goal of improving student learning. The paper discusses the challenges to evaluating school reforms in a rural context. It then reviews the international literature on each reform, assessing whether reforms were effectively implemented and whether they caused improvement in student outcomes. Even in the best cases, multigrade schools were not fully implemented. There is consistent evidence of positive effects on student achievement. Yet, the causal interpretation of evaluation findings is severely limited, especially in Guatemala and Chile. It concludes with suggestions for improving multigrade evaluations.  相似文献
