Educational stakeholders across the globe are demanding science education reform that attends simultaneously to culturally diverse students’ needs and promotes academic excellence. Although professional development programs can foster science teachers’ growth as culturally responsive educators, effective supports to this end are not well identified. This study examined associations between specific Science Teachers are Responsive to Students (STARTS) program activities and United States high school life science teachers’ understanding and enactment of culturally responsive science teaching. Findings suggest: (a) critically examining their practices while learning of students’ needs and experiences enabled teachers to identify responsive instructional strategies and relevant science topics for culturally responsive teaching; (b) evaluating culturally responsive exemplars while identifying classroom-based needs allowed teachers to identify contextually appropriate instruction, thereby yielding a robust understanding of the purpose and feasibility of culturally responsive science teaching; and (c) by justifying the use of responsive and reform-based instructional strategies for their classrooms, teachers made purposeful connections between students’ experiences and science instruction. We propose a set of empirically based design conjectures and theoretical conjectures to generate adaptable knowledge about preparing culturally responsive science teachers through professional development.  相似文献

Abstract

This article focuses on the impact of culturally relevant teaching and learning during a summer enrichment program for high school students. Culturally relevant science instruction and curriculum helped students to foster a more positive interest in science and STEM careers as it provided students the opportunity to do science in meaningful and relevant ways. Students were able to see themselves represented in the curriculum and recognized their own strengths; as a result, they were more validated and affirmed in and transformed by, their learning. We use this case to warrant increased support for summer learning programs focused on providing African American youth with access to high quality, culturally relevant/responsive science education.  相似文献

As part of a larger project aimed at promoting science and literacy for culturally and linguistically diverse elementary students, this study has two objectives: (a) to describe teachers' initial beliefs and practices about inquiry‐based science and (b) to examine the impact of the professional development intervention (primarily through instructional units and teacher workshops) on teachers' beliefs and practices related to inquiry‐based science. The research involved 53 third‐ and fourth‐grade teachers at six elementary schools in a large urban school district. At the end of the school year, teachers reported enhanced knowledge of science content and stronger beliefs about the importance of science instruction with diverse student groups, although their actual practices did not change significantly. Based on the results of this first year of implementation as part of a 3‐year longitudinal design, implications for professional development and further research are discussed. © 2004 Wiley Periodicals, Inc.

Culturally relevant science pedagogy is seldom discussed in terms of infusion of literary resources, such as adivinanzas and dichos in the design of instruction. In this study, the authors narrate how a science methods course was infused with the use of culturally responsive tools to purposefully connect to the elementary science curriculum. Results indicate that prospective Latino teachers found multiple opportunities to address specific science objectives with adivinanzas and expressed the advantages of using these culturally responsive tools to introduce and summarize science concepts as they implemented lessons during field experience.  相似文献

What teaching practices foster inquiry and promote students to learn challenging subject matter in urban schools? Inquiry‐based instruction and successful inquiry learning and teaching in project‐based science (PBS) were described in previous studies (Brown & Campione, 1990 ; Crawford, 1999 ; Krajcik, Blumenfeld, Marx, Bass, & Fredricks, 1998 ; Krajcik, Blumenfeld, Marx, & Solloway, 1994 ; Minstrell & van Zee, 2000 ). In this article, we describe the characteristics of inquiry teaching practices that promote student learning in urban schools. Teaching is a major factor that affects both achievement of and attitude of students toward science (Tamir, 1998 ). Our involvement in reform in a large urban district includes the development of suitable learning materials and providing continuous and practiced‐based professional development (Fishman & Davis, in press; van Es, Reiser, Matese, & Gomez, 2002 ). Urban schools face particular challenges when enacting inquiry‐based teaching practices like those espoused in PBS. In this article, we describe two case studies of urban teachers whose students achieved high gains on pre‐ and posttests and who demonstrated a great deal of preparedness and commitment to their students. Teachers' attempts to help their students to perform well are described and analyzed. The teachers we discuss work in a school district that strives to bring about reform in mathematics and science through systemic reform. The Center for Learning Technologies in Urban Schools (LeTUS) collaborates with the Detroit Public Schools to bring about reform in middle‐school science. Through this collaboration, diverse populations of urban‐school students learn science through inquiry‐oriented projects and the use of various educational learning technologies. For inquiry‐based science to succeed in urban schools, teachers must play an important role in enacting the curriculum while addressing the unique needs of students. The aim of this article is to describe patterns of good science teaching in urban school. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 43: 722–745, 2006  相似文献

Situated in the context of an in-service professional development (PD) program focused on Interdisciplinary Science Inquiry, this quantitative study tests the validity of and further explores the theoretical model adapted from Desimone's (2009), Educational Researcher, 38, 181–199 conceptual framework on effectiveness of PD. The participants include 204 teachers and 5,581 students within 12 local public schools from 2012 to 2016. The multilevel models indicate that PD participation, school-, and teacher-level factors influence teacher pedagogical content knowledge and inquiry instruction in different ways. Furthermore, the inquiry instruction significantly relates student understanding of interdisciplinary science concepts (ISCs) through a few mediators. Therefore, this study reinforces calls to provide teachers with high quality PD and contributes to current knowledge base of the mechanisms of how inquiry instruction influences students' understanding of ISCs.  相似文献

This research investigated the effect of reflective discussions following inquiry‐based laboratory activities on students' views of the tentative, empirical, subjective, and social aspects of nature of science (NOS). Thirty‐eight grade six students from a Lebanese school participated in the study. The study used a pretest–posttest control‐group design and focused on collecting mainly qualitative data. During each laboratory session, students worked in groups of two. Later, experimental group students answered open‐ended questions about NOS then engaged in reflective discussions about NOS. Control group students answered open‐ended questions about the content of the laboratory activities then participated in discussions of results of these activities. Data sources included an open‐ended questionnaire used as pre‐ and posttest, answers to the open‐ended questions that experimental group students answered individually during every session, transcribed videotapes of the reflective discussions of the experimental group, and semi‐structured interviews. Results indicated that explicit and reflective discussions following inquiry‐based laboratory activities enhanced students' views of the target NOS aspects more than implicit inquiry‐based instruction. Moreover, implicit inquiry‐based instruction did not substantially enhance the students' target NOS views. This study also identified five major challenges that students faced in their attempts to change their NOS views. © 2010 Wiley Periodicals, Inc. J Res Sci Teach 47: 1229–1252, 2010  相似文献

We find ourselves at a time when the need for transformation in science education is aligning with opportunity. Significant science education resources, namely the Next Generation Science Standards (NGSS) and the Ambitious Science Teaching (AST) framework, need an intentional aim of centering social justice for minoritized communities and youth as well as practices to enact it. While NGSS and AST provide concrete guidelines to support deep learning, revisions are needed to explicitly promote social justice. In this study, we sought to understand how a commitment to social justice, operationalized through culturally sustaining pedagogy (Paris, Culturally sustaining pedagogies and our futures. The Educational Forum, 2021; 85, pp. 364–376), might shape the AST framework to promote more critical versions of teaching science for equity. Through a qualitative multi-case study, we observed three preservice teacher teams engaged in planning, teaching, and debriefing a 6-day summer camp in a rural community. Findings showed that teachers shaped the AST sets of practices in ways that sustained local culture and addressed equity aims: anchoring scientific study in phenomena important to community stakeholders; using legitimizing students' stories by both using them to plan the following lessons and as data for scientific argumentation; introducing local community members as scientific experts, ultimately supporting a new sense of pride and advocacy for their community; and supporting students in publicly communicating their developing scientific expertise to community stakeholders. In shaping the AST framework through culturally sustaining pedagogy, teachers made notable investments: developing local networks; learning about local geography, history, and culture; building relationships with students; adapting lessons to incorporate students' ideas; connecting with community stakeholders to build scientific collaborations; and preparing to share their work publicly with the community. Using these findings, we offer a justice-centered ambitious science teaching (JuST) framework that can deliver the benefits of a framework of practices while also engaging in the necessarily more critical elements of equity work.  相似文献

This study assessed the influence of a 3‐year professional development program on elementary teachers' views of nature of science (NOS), instructional practice to promote students' appropriate NOS views, and the influence of participants' instruction on elementary student NOS views. Using the VNOS‐B and associated interviews the researchers tracked the changes in NOS views of teacher participants throughout the professional development program. The teachers participated in explicit–reflective activities, embedded in a program that emphasized scientific inquiry and inquiry‐based instruction, to help them improve their own elementary students' views of NOS. Elementary students were interviewed using the VNOS‐D to track changes in their NOS views, using classroom observations to note teacher influences on student ideas. Analysis of the VNOS‐B and VNOS‐D showed that teachers and most grades of elementary students showed positive changes in their views of NOS. The teachers also improved in their science pedagogy, as evidenced by analysis of their teaching. Implications for teacher professional development programs are made. © 2006 Wiley Periodicals, Inc.

We conducted a laboratory‐based randomized control study to examine the effectiveness of inquiry‐based instruction. We also disaggregated the data by student demographic variables to examine if inquiry can provide equitable opportunities to learn. Fifty‐eight students aged 14–16 years old were randomly assigned to one of two groups. Both groups of students were taught toward the same learning goals by the same teacher, with one group being taught from inquiry‐based materials organized around the BSCS 5E Instructional Model, and the other from materials organized around commonplace teaching strategies as defined by national teacher survey data. Students in the inquiry‐based group reached significantly higher levels of achievement than students experiencing commonplace instruction. This effect was consistent across a range of learning goals (knowledge, reasoning, and argumentation) and time frames (immediately following the instruction and 4 weeks later). The commonplace science instruction resulted in a detectable achievement gap by race, whereas the inquiry‐based materials instruction did not. We discuss the implications of these findings for the body of evidence on the effectiveness of teaching science as inquiry; the role of instructional models and curriculum materials in science teaching; addressing achievement gaps; and the competing demands of reform and accountability. © 2009 Wiley Periodicals, Inc.

This paper reports the results of a study of the relationship of robotics activity to the use of science literacy skills and the development of systems understanding in middle school students. Twenty‐six 11–12‐year‐olds (22 males and 4 females) attending an intensive robotics course offered at a summer camp for academically advanced students participated in the research. This study analyzes how students utilized thinking skills and science process skills characteristic of scientifically literate individuals to solve a robotics challenge. In addition, a pre/post test revealed that course participants increased their systems understanding, t (21) = 22.47, p < .05. It is argued that the affordances of the robotics environment coupled with a pedagogical approach emphasizing open‐ended, extended inquiry prompts the utilization of science literacy‐based thinking and science process skills and leads to increased systems understanding. © 2008 Wiley Periodicals, Inc.

Although science has received much attention as a political and educational initiative, students with learning disabilities (LD) perform significantly lower than their nondisabled peers. This meta‐analysis evaluates the effectiveness of instructional strategies in science for students with LD. Twelve studies were examined, summarized, and grouped according to the type of strategy implemented. Effect sizes (ES) were calculated for each study. Across all studies, a mean ES of .78 was obtained, indicating a moderate positive effect on students with LD science achievement. Findings also align with past reviews of inquiry‐based instruction for students with special needs, indicating that students with LD need structure within an inquiry science approach in order to be successful. Additionally, results suggest that mnemonic instruction is highly effective at increasing learning disabled students' acquisition and retention of science facts.  相似文献

Science education standards established by American Association for the Advancement of Science (AAAS) and the National Research Council (NRC) urge less emphasis on memorizing scientific facts and more emphasis on students investigating the everyday world and developing deep understanding from their inquiries. These approaches to instruction challenge teachers and students, particularly urban students who often have additional challenges related to poverty. We report data on student learning spanning 3 years from a science education reform collaboration with the Detroit Public Schools. Data were collected from nearly 8,000 students who participated in inquiry‐based and technology‐infused curriculum units that were collaboratively developed by district personnel and staff from the University of Michigan as part of a larger, district‐wide systemic reform effort in science education. The results show statistically significant increases on curriculum‐based test scores for each year of participation. Moreover, the strength of the effects grew over the years, as evidenced by increasing effect size estimates across the years. The findings indicate that students who historically are low achievers in science can succeed in standards‐based, inquiry science when curriculum is carefully developed and aligned with professional development and district policies. Additional longitudinal research on the development of student understanding over multiple inquiry projects, the progress of teacher enactment over time, and the effect of changes in the policy and administrative environment would further contribute to the intellectual and practical tools necessary to implement meaningful standards‐based systemic reform in science. © 2004 Wiley Periodicals, Inc.

In this article we assert a potential research agenda for the teaching and learning of science as inquiry as part of the JRST series on reform in science education. Drawing on the theoretical frameworks of cognitive and sociocultural constructivism, cultural models of meaning, the dialogic function of language, and transformational models of teacher education, we propose that more research is needed in the areas of teachers' beliefs, knowledge, and practices of inquiry‐based science, as well as, student learning. Because the efficacy of reform efforts rest largely with teachers, their voices need to be included in the design and implementation of inquiry‐based curriculum. As we review the literature and pose future research questions, we propose that particular attention be paid to research on inquiry in diverse classrooms, and to modes of inquiry‐based instruction that are designed by teachers. © 2001 John Wiley & Sons, Inc.

This study continues research previously conducted by a nine‐university collaborative, the Salish I Research Project, by exploring science teachers' beliefs and practices with regard to inquiry‐oriented instruction. In this study, we analyzed the relationship among secondary science teachers' preparation, their beliefs, and their classroom practices after completion of a course designed to provide authentic inquiry experiences. From Teacher Pedagogical Philosophy Interview data and Secondary Science Teacher Analysis Matrix observational data, we analyzed links between the teachers' conveyed beliefs and observed practice regarding the teachers' actions (TA) and students' actions (SA). Also presented is a listing of teachers' perceived influences from university preparation course work. Results indicated that 7 of the 8 teachers professed a belief in teacher‐centered or conceptual style with regard to TA and SA. The observational results indicated that 7 of the 8 teachers displayed a teacher‐centered or conceptual style with regard to TA and SA. Inconsistencies between interview and observational data were unexpected, as half of the teachers professed slightly greater teacher‐centered styles with regard to TA than what they actually practiced in their classrooms. All teachers reported that an inquiry‐based science course was valuable. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 43: 938–962, 2006  相似文献

To help explain the differences in students' performance on internationally administered science assessments, cross-national, video-based observational studies have been advocated, but none have yet been conducted at the elementary level for science. The USA and Germany are two countries with large formal education systems whose students underperform those from peers on internationally administered standardized science assessments. However, evidence from the 2011 Trends in International Mathematics and Science Exam assessment suggests fourth-grade students (9–10 year-olds) in the USA perform higher than those in Germany, despite more instructional time devoted to elementary science in Germany. The purpose of this study is to comparatively analyze fourth-grade classroom science in both countries to learn more about how teachers and students engage in scientific inquiry, particularly explanation-construction. Videorecordings of US and German science instruction (n 1?=?42, n 2?=?42) were sampled from existing datasets and analyzed both qualitatively and quantitatively. Despite German science lessons being, on average, twice as long as those in the USA, study findings highlight many similarities between elementary science in terms of scientific practices and features of scientific inquiry. However, they also illustrate crucial differences around the scientific practice of explanation-construction. While students in German classrooms were afforded more substantial opportunities to formulate evidence-based explanations, US classrooms were more strongly characterized by opportunities for students to actively compare and evaluate evidence-based explanations. These factors may begin to help account for observed differences in student achievement and merit further study grounded in international collaboration.  相似文献

Reform efforts in science education emphasize the importance of supporting students' construction of knowledge through inquiry. Project‐based science (PBS) is an ambitious approach to science instruction that addresses concerns of reformers. A sample of 142 10th‐ and 11th‐grade students enrolled in a PBS program completed the 12th‐grade 1996 National Assessment of Educational Progress (NAEP) science test. Compared with subgroups identified by NAEP that most closely matched our student sample, White and middle class, PBS students outscored the national sample on 44% of NAEP test items. This study shows that students participating in a PBS curriculum were prepared for this type of testing. Educators should be encouraged to use inquiry‐based approaches such as PBS to implement reform in their schools. © 2002 Wiley Periodicals, Inc. J Res Sci Teach 39: 410–422, 2002  相似文献

The Science Teachers Learning from Lesson Analysis (STeLLA) project is a videobased analysis‐of‐practice PD program aimed at improving teacher and student learning at the upper elementary level. The PD program developed and utilized two “lenses,” a Science Content Storyline Lens and a Student Thinking Lens, to help teachers analyze science teaching and learning and to improve teaching practices in this year‐long program. Participants included 48 teachers (n = 32 experimental, n = 16 control) and 1,490 students. The STeLLA program significantly improved teachers' science content knowledge and their ability to analyze science teaching. Notably, the STeLLA teachers further increased their classroom use of science teaching strategies associated with both lenses while their students increased their science content knowledge. Multi‐level HLM analyses linked higher average gains in student learning with teachers' science content knowledge, teachers' pedagogical content knowledge about student thinking, and teaching practices aimed at improving the coherence of the science content storyline. This paper highlights the importance of the science content storyline in the STeLLA program and discusses its potential significance in science teaching and professional development more broadly. © 2011 Wiley Periodicals, Inc., J Res Sci Teach 48: 117–148, 2011  相似文献

ABSTRACT

This study investigates the discrete effects of inquiry-based instructional practices that described the PISA 2015 construct ‘inquiry-based instruction’ and how each practice, and the frequency of each practice, is related to science achievement across 69 countries. The data for this study were drawn from the PISA 2015 database and analysed using hierarchical linear modelling (HLM). HLMs were estimated to test the contribution of each item to students’ science achievement scores. Some inquiry practices demonstrated a significant, linear, positive relationship to science achievement (particularly items involving contextualising science learning). Two of the negatively associated items (explaining their ideas and doing experiments) were found to have a curvilinear relationship to science achievement. All nine items were dummy coded by the reported frequency of use and an optimum frequency was determined using the categorical model and by calculating the inflection point of the curvilinear associations in the previous model e.g. students that carry out experiments in the lab in some lessons have higher achievement scores than students who perform experiments in all lessons. These findings, accompanied by detailed analyses of the items and their relationships to science outcomes, give stakeholders clear guidance regarding the effective use of inquiry-based approaches in the classroom.  相似文献
