Reform based curriculum offer a promising avenue to support greater student achievement in science. Yet teachers frequently adapt innovative curriculum when they use them in their own classrooms. In this study, we examine how 19 teachers adapted an inquiry‐oriented middle school science curriculum. Specifically, we investigate how teachers' curricular adaptations (amount of time, level of completion, and activity structures), teacher self‐efficacy (teacher comfort and student understanding), and teacher experience enacting the unit influenced student learning. Data sources included curriculum surveys, videotape observations of focal teachers, and pre‐ and post‐tests from 1,234 students. Our analyses using hierarchical linear modeling found that 38% of the variance in student gain scores occurred between teachers. Two variables significantly predicted student learning: teacher experience and activity structure. Teachers who had previously taught the inquiry‐oriented curriculum had greater student gains. For activity structure, students who completed investigations themselves had greater learning gains compared to students in classrooms who observed their teacher completing the investigations as demonstrations. These findings suggest that it can take time for teachers to effectively use innovative science curriculum. Furthermore, this study provides evidence for the importance of having students actively engaging in inquiry investigations to develop understandings of key science concepts. © 2010 Wiley Periodicals, Inc., J Res Sci Teach 48: 149–169, 2011  相似文献

Inquiry-based curricula are an essential tool for reforming science education yet the role of the teacher is often overlooked in terms of the impact of the curriculum on student achievement. Our research focuses on 22 teachers’ use of a year-long high school urban ecology curriculum and how teachers’ self-efficacy, instructional practices, curricular enactments and previous experience impacted student learning. Data sources included teacher belief surveys, teacher enactment surveys, a student multiple-choice assessment focused on defining and identifying science concepts and a student open-ended assessment focused on scientific inquiry. Results from the two hierarchical linear models indicate that there was significant variation between teachers in terms of student achievement. For the multiple-choice assessment, teachers who spent a larger percentage of time on group work and a smaller percentage of time lecturing had greater student learning. For the open-ended assessment, teachers who reported a higher frequency of students engaging in argument and sharing ideas had greater student learning while teachers who adapted the curriculum more had lower student learning. These results suggest the importance of supporting the active role of students in instruction, emphasising argumentation, and considering the types of adaptations teachers make to curriculum.  相似文献

ABSTRACT

We first examined the effects of a year-long professional development (PD) programme for elementary science teachers on fifth grade student performance on state-mandated science achievement tests of students from a treatment and a comparison group of teachers in the 2009–2010 academic year. Then, we investigated the longer-term impacts by comparing the 2010–2011 student test results of the teachers one year after receiving treatment in 2009–2010 with the students of teachers who received treatment during 2010–2011. Test scores were analysed using a propensity score matching method to examine the relationship between the PD and student achievement. Results showed that even though the treatment teachers were out of the classroom 20% of the school year to attend the PD, there was no difference between their students’ science achievement scores and those of the comparison teachers who were in the classroom every day. This is an important finding because many principals and parents are reluctant to provide teachers with release time for PD. We also determined that students of teachers one year after participating in the PD significantly (p?<?0.001) with a medium effect size (η2?=?.088) outperformed students of teachers who had just completed the programme. This suggests that it takes time for teachers to implement new teaching strategies and that to observe the impact of an intervention programme, it may be important to expand the timeframe of the programme evaluation.  相似文献

This is one of a series of studies conducted by a high school physics teacher, who used constructivist referents to plan and enact the curriculum, and to understand and improve the learning environment in his physics classes. Data were collected in the course of a two-year physics course including (a) repeated administrations of a classroom learning environment survey, (b) written essays on the topics of knowing, learning, and classroom learning environment, and (c) interviews. While there was a general trend for students to adopt more constructivist views of knowing and learning, there was also a small number who resisted to adapt to the constructivist learning environment in their physics course. Two case studies of individual students are used to illustrate the interactions of the learning environment, student understanding of scientific knowledge, and the nature of science, and students' views of their own learning.  相似文献

This article examines secondary-school physics teaching with respect to three levels of curriculum. These are the curriculum as designed by educational authorities and intended for school guidance, as perceived by teachers and translated into classroom practice, and as internalized by students and expressed by achievement on physics tests. In keeping with international usage we refer to these levels of curriculum as the intended, the translated and the achieved. The article is based upon the analysis of curriculum documents and guidelines, teacher assessments of opportunity provided students to learn, and student achievement on a comprehensive physics test. The context for analysis is provided by an ongoing international study of science education in which some 30 participating countries analyze the three curriculum levels and attempt to draw conclusions concerning possible relationships among them. The article reports limited but nevertheless significant relationships found among intentions, translations, and achievement in the teaching of physics in Canadian secondary schools.  相似文献

This study investigates the effect of physics education on students' achievement in a large‐scale quantitative study of pre‐academic high school students throughout the Netherlands. Two aspects of teacher characteristics as perceived by their students are included: their “pleasantness” principally defined by their perceived friendliness and positive feedback and their “centeredness” principally defined by the perceived teacher centeredness in the lessons. Furthermore, this study includes four student aspects: their “general capability,” their “quantity of work,” their “quality of work,” and their “interest in the lessons.” Structural Equation Modeling is used in order to cluster the different variables defining the perceived pleasantness and the perceived centeredness of the teacher and the general capability, interest, and learning attitudes of the students. Furthermore, interrelations among these components and students' achievement are analyzed. Eventually, a very large effect of the students' general capability (61–72%) and a remarkably smaller effect of the remaining parameters (<3%) on achievement are detected. However, one should not yet conclude that teacher effect on high‐achieving‐students' achievement is consistently low. To the contrary, these results should be seen as an incentive to consider nonlinear effects, to vary ones viewpoint and to include more/other variables. In spite of the almost negligible correlation between the measured aspects of the physics teachers and achievement, the correlations between the teacher variables and the remaining student variables are quite significant. Both the perceived pleasantness and the centeredness of the teachers have a significant effect on the interest of their students. Furthermore, the pleasantness of the teacher correlates with the quality of the students' work and the centeredness of the teacher with their quantity of work. © 2012 Wiley Periodicals, Inc.

Despite the wide agreement among educators that classroom learning and teaching processes can gain much from student and teacher questions, their potential is not fully utilized. Adopting the view that reporting both teachers’ (of varying age groups) views and actual classroom practices is necessary for obtaining a more complete view of the phenomena at hand, the present study closely examines both cognitive and affective domains of: (a) teachers’ views (via interviews) concerning: (1) importance and roles of teacher and student questions, (2) teacher responses, and (3) planning and teacher training; and (b) teachers’ actual practices (via classroom observations) concerning: (1) number and (2) level of teacher and student questions, as well as (3) teachers’ responses to questions. The data were collected from 3 elementary, 3 middle, and 3 high school science teachers and their respective classroom students. The findings lay out a wide view of classroom questioning and teachers’ responses, and relate what actually occurs in classes to teachers’ stated views. Some of the study’s main conclusions are that a gap exists between how science researchers and teachers view the role of teacher questions: the former highlight the cognitive domain, while the latter emphasize the affective domain.  相似文献

The present study investigates whether teacher perceptions of students’ cognitive skills, their learning motivation, and their classroom behavior differ according to students’ socioeconomic status, immigrant background, and gender. Data from N = 4746 German fourth graders and data from their parents and teachers were analyzed using structural equation modeling. Controlling for student achievement as measured in a standardized achievement test and student motivation as measured by student and parent reports, we found that teachers overestimated the cognitive skills of high-SES students and girls in comparison to those of low-SES students and boys. Similarly, teachers perceived high-SES students, students who are not from an immigrant background, and girls as having a higher learning motivation and as having more cognitive skills. Finally, we found that teachers’ perceptions of students’ learning motivation and classroom behavior mediated the relationship between student characteristics and cognitive skills as perceived by the teacher.  相似文献

In this paper, we consider whether teachers' explicit and implicit prejudiced attitudes underlie the ethnic achievement gap. To date, most research on teacher expectation effects has relied on explicit expectation measures that are prone to social desirability biases. In contrast, we examine the effects of teachers' (a) explicit ethnicity-based expectations for academic achievement and (b) implicit prejudiced attitudes about academic achievement on students' actual academic success over time. A total of 38 teachers completed both a traditional teacher expectation measure and a modified Implicit Association Task designed to assess ethnic stereotypes associated with academic achievement and failure. A multi-level analytic framework showed that students in classrooms of teachers with high expectations performed better in reading at the end of the year and that these effects were found across all ethnic groups. In contrast, whereas students' mathematics achievement scores were largely unrelated to teachers' explicit expectations, teachers' implicit prejudiced attitudes predicted student performance. Specifically, students benefited most academically when their teachers' implicit biases favored the ethnic group to which the student belonged. Findings are discussed in relation to differences in the salience of teachers' expectations and implicit prejudiced attitude in the classroom, and the ethnic achievement gap.  相似文献

This paper examines students’ achievement and interest and the extent to which they are predicted by teacher knowledge and motivation. Student achievement and interest are both considered desirable outcomes of school instruction. Teacher pedagogical content knowledge has been identified a major predictor of student achievement in previous research, whereas teacher motivation is considered a decisive factor influencing students’ interest. So far, however, most research either focused on knowledge or motivation (both on the students’ as well as the teachers’ side), rarely investigating them together or examining the instructional mechanisms through which the supposed effects of teacher knowledge and motivation are facilitated. In the present study, N = 77 physics teachers and their classes in Germany and Switzerland are investigated utilizing a multi‐method approach in combining data obtained from test‐instruments (teacher pedagogical content knowledge, student achievement) and questionnaires (teacher motivation, student interest, student perceived enthusiastic teaching) as well as videotaped instruction (cognitive activation rated by observers). Multi‐level structural equation modeling was used to support the assumptions that teacher pedagogical content knowledge positively predicted students’ achievement; the effect was mediated by cognitive activation. Teachers’ motivation predicted students’ interest which was mediated by enthusiastic teaching as perceived by students. Neither did teacher pedagogical content knowledge predict students’ interest, nor teacher motivation students’ achievement. This implies that in order to improve students’ cognitive as well as affective outcomes, both teachers’ knowledge but also their motivation need to be considered. © 2016 The Authors.

There is increasing evidence of a gap between curricular requirements and what students actually want to know. One of the factors influencing what is taught in the classroom is teachers’ attitudes towards integrating their students’ interests. This study investigated what prompts high-school teachers who prepare students for national matriculation examination to adjust the curriculum to match their students’ interests. In the first stage of the study, 350 students’ biology questions that are not covered by the Israeli biology curriculum were presented to 15 experienced biology teachers. These teachers provided 19 reasons why they would or would not address these questions in their teaching. In stage 2, these 19 reasons were presented to another 175 high-school teachers from different disciplines. These teachers were asked to rank the importance of each reason in deciding whether to include or exclude topics raised by the student which are not required by the curriculum. Based on these answers, the 19 reasons were classified into four groups: civic literacy, curricular compatibility, topic suitability, and curricular limitations. The findings show that demographic factors such as gender, experience, and sector, as well as the subject taught by the teacher, all influence decisions. Thus, many teachers are aware of the interest gap, but the solutions and the attention given to this problem vary.  相似文献

ABSTRACT

Background: Physics is often seen as a discipline with difficult content, and one that is difficult to identify with. Socialisation processes at the upper secondary school level are of particular interest as these may be linked to the subsequent low and uneven participation in university physics. Focusing on how norms are construed in physics classrooms in upper secondary school is therefore relevant.

Purpose: The purpose of this paper is to identify discursive patterns in teacher–student interactions in physics classrooms.

Design and methods: Three different physics lessons with one class of students taught by three different teachers in upper secondary school were video-recorded. Positioning theory was used to analyse classroom interaction with a specific focus on how physics was positioned.

Results: We identified seven different storylines. Four of them (‘reaching a solution to textbook problems’, ‘discussing physics concepts in order to gain better understanding’, ‘doing empirical enquiry’ and ‘preparing for the upcoming exam’) represent what teaching physics in an upper secondary school classroom can be. The last three storylines (‘mastering physics’, ‘appreciating physics’ and ‘having a feeling for physics’) all concern how students are supposed to relate to physics and, thus, become ‘insiders’ in the discipline.

Conclusions: The identification and analysis of storylines raises awareness of the choices teachers make in physics education and their potential consequences for students. For example, in the storyline of mastering physics a good physics student is associated with ‘smartness’, which might make the classroom a less secure place in general. Variation and diversity in the storylines construed in teaching can potentially contribute to a more inclusive physics education.  相似文献

As part of a project concerned with developing a better understanding of the detail of appropriate teaching of direct current (DC) electricity concepts, extensive individual interviews were conducted with a number of experienced senior high school physics teachers. These interviews explored teachers’ perceptions of difficulties in student learning and their own teaching of DC electricity, their uses of models and analogies in this teaching, and their own understandings of the concepts of DC electricity. Eight high school physics teachers from the Australian state of Victoria were interviewed: three who had a strong focus on student understanding in their classrooms and five who used more traditional approaches. We also interviewed three authors of textbooks then currently used in senior high school physics in Victoria, all of whom were also teachers of high school physics. All but one of these eleven interviewees was a very experienced teacher of DC electricity at the senior high school level. The interview data are summarized and implications for curriculum and teaching/learning of electricity are considered. There was a wide range of views among the teachers about the difficulties of both the concepts of DC electricity and the teaching of these concepts, and about the nature of physics knowledge. A number of the interviewees revealed levels of conceptual understanding that we see as of concern. Some of the teachers whose understanding causes us concern made clear early in the interview their view that the concepts of DC electricity were essentially straight forward; in all cases these interviewees had by the end of the interview reconsidered this position.  相似文献

We investigated how Chinese physics teachers structured classroom discourse to support the cognitive and social aspects of inquiry-based science learning. Regarding the cognitive aspect, we examined to what extent the cognitive processes underlying the scientific skills and the disciplinary reasoning behind the content knowledge were taught. Regarding the social aspect, we examined how classroom discourse supported student learning in terms of students' opportunities to talk and interaction patterns. Our participants were 17 physics teachers who were actively engaged in teacher education programs in universities and professional development programs in local school districts. We analyzed one lesson video from each participating teacher. The results suggest both promises and challenges. Regarding the cognitive aspect of inquiry, the teachers in general recognized the importance of teaching the cognitive processes and disciplinary reasoning. However, they were less likely to address common intuitive ideas about science concepts and principles. Regarding the social aspect of inquiry, the teachers frequently interacted with students in class. However, it appeared that facilitating conversations among students and prompting students to talk about their own ideas are challenging. We discuss the implications of these findings for teacher education programs and professional development programs in China.  相似文献

Background: This study investigates the role of figures of speech in the process of conceptual change in the physics classroom. Purpose: Its objectives are to examine what teachers and students perceive to be the advantages in using figures of speech in teaching physics concepts, what they perceive to be the challenges in using them, and how teachers use these in their classrooms to minimize the challenges faced. Sample We chose a purposive sample of 95 students and nine teachers of physics, in four schools in Lebanon. Design and methods: A mixed-method approach was used. Interviews were conducted with physics teachers; questionnaires were distributed to students, and non-participant classroom observations were carried out. Results: Teachers viewed figures of speech as a tool that helps them transmit abstract physics concepts to students in a simpler and concrete way. Questionnaires and non-participant observations revealed several examples of figures of speech used and the positive responses of students towards them. Conclusions: The study suggests several ways to overcome the drawbacks. This study highlights the urgent need for all stakeholders to work collaboratively to include figures of speech in the curriculum to enhance the process of conceptual change in the physics classroom.  相似文献

Conclusions Of all the aspects of classroom environment studied in this research, attention to the social relevance of physics had one of the strongest associations, in a positive sense, with each of the student outcomes. The research showed that positive student outcomes tended to be closely associated with low levels of frustration. Integration of experimental and theoretical aspects of physics tended to be accompanied by positive student outcomes. The integration could well go beyond using experiments merely to illustrate and/or verify principles and theories previously taught. At least in some topics, student understanding of physics could well follow upon and be the outcome of experiences gained during practical work, and some problem-solving by experiments could be given. Despite some inveitable tensions, teachers who favoured student autonomy were generally satisfied with their physics teaching. Moreover, their students reported more growth in personal development areas such as a sense of responsibility than did students who did not experience much autonomy. The multi-media characteristics of Project Physics makes it a particularly suitable approach for including student autonomy. The results indicated that academic achievement is not likely to suffer when attention is given to encouraging student initiative, sense of responsibility, improved study methods and persistence at a task. Such goals are long-term goals and working towards them tends to be accompanied by greater interest in and enjoyment of physics.  相似文献

In this study, we examine the relationship between contextual variables related to teachers and student performance in Advanced Algebra classrooms in the USA. The data were gathered from a cluster-randomized study on the effects of SimCalc MathWorlds®, a curricular and technological intervention as a replacement for Algebra 2 curriculum, on student learning of Algebra 2 content. Conditional measures (teacher background characteristics) and instructional measures (self-reported instructional preferences, stances, and classroom practices) were subjected to a variety of empirical analyses to discern their relationship to student learning. Researchers examined both the overall effect of teacher contextual variables on student learning and the specific effect of SimCalc on both teacher instructional measures and student performance. There is evidence to support that teachers who use the SimCalc curriculum value classroom communication, deep understanding of math concepts, and support for both routine and non-routine problems.  相似文献

Assessment of student learning outcomes is often discussed in relation to curriculum, standards and even administration practices. However, assessment of learning outcomes is rarely discussed in light of students’ socio-emotional contexts, which might help or hinder learning outcomes. For example, do students’ perceptions of the teacher as trustworthy influence their empathic views on classmates, learning engagement, academic achievement and wellbeing? The present paper reports the results of a theoretically-driven, short-term longitudinal study designed to explore the effects of socio-emotional variables, specifically students’ trust in teachers and empathy towards self and peers on engagement for learning, academic achievement, and wellbeing. Grounded in attachment theory and the LEAFF model, Panel Structural Equation Modeling (P-SEM) results revealed three significant pathways, which provide evidence that student trust in teachers may serve to launch a domino effect of outcomes, predicting students’ empathic views of classmates, learning engagement, academic achievement, and wellbeing.  相似文献
