Recent instructional reforms in science education aim to change the way students engage in learning in the discipline, as they describe that students are to engage with disciplinary core ideas, crosscutting concepts, and the practices of science to make sense of phenomena (NRC, 2012). For such sensemaking to become a reality, there is a need to understand the ways in which students' thinking can be maintained throughout the trajectory of science lessons. Past research in this area tends to foreground either the curriculum or teachers' practices. We propose a more comprehensive view of science instruction, one that requires attention to teachers' practice, the instructional task, and students' engagement. In this study, by examining the implementation of the same lesson across three different classrooms, our analysis of classroom videos and artifacts of students' work revealed how the interaction of teachers' practices, students' intellectual engagement, and a cognitively demanding task together support rigorous instruction. Our analyses shed light on their interaction that shapes opportunities for students' thinking and sensemaking throughout the trajectory of a science lesson. The findings provide implications for ways to promote rigorous opportunities for students' learning in science classrooms.  相似文献

This article focuses on ion and ways in which students cope with abstraction. The article has two goals: first, it illustrates how the theme of reducing abstraction (Hazzan, 1999) is useful for analyzing students' thinking about abstract concepts in mathematics and in computer science; second, it demonstrates how theories based on mathematics education research can be applied to analyzing students' understanding of computer science concepts. The main section of the article analyzes the understanding of concepts from four fields – abstract algebra, computability, data structures and differential equations – through the lens of reducing abstraction. The analysis shows that a wide range of cognitive phenomena can be explained by one theoretical framework.  相似文献

This article reports on analyses of the instructional practices of six middle- and high-school science teachers in the United States who participated in a research-practice partnership that aims to support reform science education goals at scale. All six teachers were well qualified, experienced, and locally successful—respected by students, parents, colleagues, and administrators—but they differed in their success in supporting students' three-dimensional learning. Our goal is to understand how the teachers' instructional practices contributed to their similarities in achieving local success and to differences in enabling students' learning, and to consider the implications of these findings for research-practice partnerships. Data sources included classroom videos supplemented by interviews with teachers and focus students and examples of student work. We also compared students' learning gains by teacher using pre–post assessments that elicited three-dimensional performances. Analyses of classroom videos showed how all six teachers achieved local success—they led effectively managed classrooms, covered the curriculum by teaching almost all unit activities, and assessed students' work in fair and efficient ways. There were important differences, however, in how teachers engaged students in science practices. Teachers in classrooms where students achieved lower learning gains followed a pattern of practice we describe as activity-based teaching, in which students completed investigations and hands-on activities with few opportunities for sensemaking discussions or three-dimensional science performances. Teachers whose students achieved higher learning gains combined the social stability characteristic of local classroom success with more demanding instructional practices associated with scientific sensemaking and cognitive apprenticeship. We conclude with a discussion of implications for research-practice partnerships, highlighting how partnerships need to support all teachers in achieving both local and standards-based success.  相似文献

Current science education reforms highlight the importance of students making sense of scientific ideas. While research has studied how to support sensemaking in classrooms, we still know very little about what drives students to pursue and persist in it on their own. In this article, we use a set of parallel case studies of undergraduate students discussing introductory physics to show how certain student-generated, vexing questions both initiate and sustain students' sensemaking processes. We examine affective and linguistic markers in student discourse in paired-clinical interviews to demonstrate both of these functions of vexing questions and detail their role in the explanations students construct. We conclude by discussing the implications of this analysis both for supporting sensemaking in classrooms and for studying it in research.  相似文献

Zimbabwe's Belvedere Technical Teachers' College requires students to complete a Curriculum Depth Studies (CDS) project investigating some aspect of their teaching. The Professional Studies (PS) section at the college is undergoing an action research project to improve how students are prepared for and supported in doing their CDS projects. At the same time, the section is promoting action research as a model for the students' projects. By participating in the process that they are advocating, PS section lecturers examined the complexities of doing action research. The college-wide dialogue reflects the deep thinking, tensions and contradictions involved in the process  相似文献

Attaining the vision for science teaching and learning emphasized in the Framework for K‐12 Science Education and the next generation science standards (NGSS) will require major shifts in teaching practices in many science classrooms. As NGSS‐inspired cognitively demanding tasks begin to appear in more and more science classrooms, facilitating students' engagement in high‐level thinking as they work on these tasks will become an increasingly important instructional challenge to address. This study reports findings from a video‐based professional development effort (i.e., professional development [PD] that use video‐clips of instruction as the main artifact of practice to support teacher learning) to support teachers' learning to select cognitively demanding tasks and to support students' learning during the enactment of these tasks in ways that are aligned with the NGSS vision. Particularly, we focused on the NGSS's charge to get students to make sense of and deeply think about scientific ideas as students try to explain phenomena. Analyses of teachers' pre‐ and post‐PD instruction indicate that PD‐participants began to adopt instructional practices associated with facilitating these kinds of student thinking in their own classrooms. The study has implications for the design of video‐based professional development for science teachers who are learning to facilitate the NGSS vision in science classrooms.  相似文献

The purpose of this research was to demonstrate an empirical relationship between classroom community and students' achievement goals in higher education, and to offer a possible explanation for differences in this relationship for cooperative and non-cooperative classrooms. Structural equation modeling techniques revealed that students' perceptions of interactive learning significantly mediated the relationship between students' goals and their sense of classroom community, but only for classrooms that used cooperative learning techniques. In the traditional lecture-style course surveyed, students' feelings of classroom community and interactive learning were significantly lower than in cooperative learning classrooms. Finally, while mastery goals were significantly higher for cooperative learning students, performance-approach goals were significantly higher for traditional lecture students.  相似文献

As part of a project to identify opportunities for reasoning that occur in good but typical science classrooms, this study focuses on how sixth graders reason about the goals and strategies of experimentation and laboratory activities in school. Collaborating with teachers, we explore whether reasoning can be deepened by developing instruction that capitalizes more effectively on the classroom opportunities that arise for fostering complex thinking and understanding. The design of the study includes (a) a baseline interview probing students' understanding of experimentation in the context of a standard, 40-min "hands-on" activity that is part of the standard sixth-grade curriculum; (b) a 3-week teaching study, in which five teachers, informed by the cognitive science research concerning the development of scientific reasoning, designed and taught a special experimentation unit in their classrooms; and (c) a series of follow-up interviews, in which students' understanding of experimentation was reexamined. The findings from the two learning contexts-one more supportive of student reasoning than the other-inform us about the kinds of reasoning that are developing in middle-school students and the forms of instruction best suited to exercising those developing skills.  相似文献

Preparing teachers for inclusive classrooms   总被引：2，自引：0，他引：2  
Effective teaching skills consist of high levels of student engagement based on good classroom and time management skills; the ability to scaffold learning that is adapted to students' current levels of understanding; cognitively engaging students in higher-order thinking; and encouraging and supporting success. The research reported here suggests that in elementary classrooms, effective teaching skills are effective for all students, both with and without special education needs.  相似文献

Why do some students avoid seeking help in the classroom when they need it? When students do not seek the help they need, they put themselves at a disadvantage for learning. We discuss how students' personal motivational characteristics relate to their avoidance of help seeking. In particular, we discuss our work regarding perceived academic and social competence and achievement- and social-goal orientations. We also discuss how various dimensions of the classroom context relate to help avoidance. Specifically, we discuss rules and norms of classrooms as well as our work examining the achievement goal structure and social climate of classrooms. We conclude by discussing how new developments in achievement goal theory distinguishing between approach- and avoidance-goal orientations might add to psychologists' understanding of help avoidance. We also consider how students' strivings for autonomy and different aspects of the social climate might be incorporated into theories of students' help avoidance behavior.  相似文献

This article discusses the process of a study designed to develop university students' sketching skills in schools of architecture. Acknowledging the relationship between cognition and writing, it aims to investigate the role of writing in learning sketching among architecture students and to examine how students regulate their thoughts by writing as they work on their free hand sketches. It includes writing texts before and after sketching tasks to improve sketching. The study was implemented in a school of architecture at a Turkish university as part of an elective course on sketching. The students' works were evaluated in terms of their sketches, texts and self‐reports of their thinking and the views and comments of the tutor who carried out the programme. This article discusses how the study was conceived and developed. The results of this study may provide insights for educators in developing strategies in teaching and learning of sketching and design, using multi modes of thinking.  相似文献

Meaningful participation in science and engineering practices requires that students make their thinking visible to others and build on one another's ideas. But sharing ideas with others in small groups and classrooms carries social risk, particularly for students from nondominant groups and communities. In this paper, we explore how students' perceptions of classrooms shape their contributions to classroom knowledge building in science across a wide range of classrooms. We examine the claim that when students feel a sense of belonging in class, they contribute more and perceive their ideas to be more influential in knowledge building. Data comes from classroom exit tickets (n = 10,194) administered in 146 classrooms as part of a 10-state field test of a new middle-school science curriculum, OpenSciEd, which were analyzed using mixed effects models. We found that students' sense of belonging predicted the degree to which they contributed ideas out loud in class (Odds ratio = 1.57) as well as the degree to which they perceived their contributions as influencing others (Odds ratio = 1.53). These relationships were particularly strong for students who reported a lower a sense of belonging. We also found significant differences by both race and gender in whether students said they contributed and believed their ideas influenced those of others. These findings suggest that a learner's sense of belonging in class and willingness to contribute may be mutually reinforcing, highlighting the need to promote content-specific strategies to foster belonging in ways that support collaborative knowledge building.  相似文献

The increasing number of people studying abroad has drawn significant scholarly attention to the experiences of international students. While these works have productively informed policy and practice regarding how international students may be better supported, they have not always considered the active ways international students contribute to higher education. This article suggests that adopting the notion of experience as a conceptual starting point is problematic because it only partially illuminates international students' agency and reproduces understandings of them as a vulnerable group. The more active notion of practice, by contrast, suggests a more agentive subject who is a pivotal actor in spaces of education. The main argument in this article is that the abiding focus on international students' experiences will be productively unsettled by orienting attention to their practices and theorising the notion of practice in more fluid and dynamic ways. After critically engaging with the existing literature, the article outlines four ways that a focus on international students' practices may reanimate debates. A focus on practice will: (1) show how international students actively contribute to spaces of higher education, including classrooms, campuses and other sites of sociality; (2) demand that researchers theorise agency in more expansive ways and consider the practices of a broader set of social groups; (3) encourage researchers to make use of a wider set of qualitative research methods; and (4) create a stronger political foundation from which to defend the interests of international students in a post-COVID-19 world.  相似文献

Learning environment,motivation, and achievement in high school science   总被引：1，自引：0，他引：1  
In a study of the relationship between high school students' perceptions of their science learning environments and their motivation, learning strategies, and achievement, 377 students in 22 introductory science classrooms completed surveys in the fall and spring of their ninth‐grade year. Hierarchical linear regression was used to model the effects of variables at both the classroom and individual level simultaneously. High intraclass agreement (indicated by high parameter reliability) on all classroom environment measures indicated that students shared perceptions of the classroom learning environment. Controlling for other factors, shared perceptions that only the most able could succeed in science classrooms and that instruction was fast‐paced and focused on correct answers negatively predicted science achievement, as measured on a districtwide curriculum‐linked test. Shared perceptions that classrooms focused on understanding and independent thinking positively predicted students' self‐reported satisfaction with learning. Implications of these results for both teaching and research into classroom environments are discussed. © 2003 Wiley Periodicals, Inc. J Res Sci Teach 40: 347–368, 2003  相似文献

The efficacy of placing students with special needs in inclusive classrooms may depend in part on how instructional factors contribute to student outcomes. Differences in frequencies and levels of cognitive engagement of interactions among nine teachers in inclusive elementary classrooms were related to three other variables: teachers' ratings on the Pathognomonic-Interventionist (PATH/INT) Scale, students' designation either as exceptional or at-risk (EX/AR) or as typically achieving (TA), and students' scores on the Piers Harris Children's Self-Concept Scale. Teachers with PATH beliefs, who attribute learning difficulties to permanent characteristics of the student that are beyond the teacher's mandate, interacted infrequently with their EX/AR students at low levels of cognitive engagement. Teachers with INT beliefs, who see themselves as responsible for the achievement of all their students irrespective of their disabilities, interacted with all students more frequently, and at higher levels of cognitive engagement. In contrast to the PATH teachers, their EX/AR students received more instructional interactions than their TA students. As expected, the EX/AR students in all classrooms had lower Piers Harris Self-Concept Total Scale scores than typically achieving students. However, both TA and EX/AR students had lower Self-Concept Total Scale scores in the classrooms of teachers with PATH beliefs, compared to students in the classrooms of INT teachers. The relationship is discussed between teachers' beliefs, their different patterns of instructional interactions with students with and without disabilities in inclusive classrooms, and the possible impact of instructional interventions on students' self-concept.  相似文献

This article discusses students' pedagogical thinking in situations where the use of information and communication technologies (ICTs) has a (well-defined) pedagogical role and rationale. By analysing students' pedagogical thinking in this setting, it is also possible to better understand their motivations and self-regulation. Pedagogical thinking as viewed from the student's angle is a new area of educational research. Our research method is a combination of the Stimulated Recall interview and the semi-structured theme interview. In addition, some background data were gathered by questionnaire to discern students' different uses of ICTs and their contexts. The findings suggest how the educational use of ICTs is considered to be meaningful and motivating by both genders and among all the interviewed age groups, in spite of the fact that an acute and vocal critique seems to develop among older students. The differences reside in students' reasoning regarding decision making in task operations between genders, which was one of the background variables—girls actively include identity and opinion, while boys emphasize the quality of performance as motives for decisions.  相似文献

To effectively cultivate students' growth mindset, it is important to identify contextual factors that may communicate mindset messages to students. The present study examined the association of students' growth mindset with various dimensions of teacher beliefs (mindset, self-efficacy), teaching practices (guided inquiry, group work, task differentiation, in-class ability grouping, mastery and normative evaluations), and school climate (holistic development, in-school ability grouping). Participants were 2200 ten-year-old students, 358 teachers, and 65 principals from Finnish elementary schools that participated in the OECD Survey on Social and Emotional Skills. Multilevel analyses show that students endorsed more of a growth mindset in classrooms where teachers used guided inquiry and in schools that emphasized students' social-emotional development. In contrast, students endorsed more of a fixed mindset when teachers assigned different tasks to different students based on ability. Implications for how to combine teaching practices to support students’ growth mindset are discussed.  相似文献

This investigation examined 10th‐grade biology students' decisions to enroll in elective science courses, and explored certain attitudinal perceptions of students that may be related to such decisions. The student science perceptions were focused on student and classroom attitudes in the context of differing learning cycle classrooms (high paradigmatic/high inquiry, and low paradigmatic/low inquiry). The study also examined possible differences in enrollment decisions/intentions and attitudinal perceptions among males and females in these course contexts. The specific purposes were to: (a) explore possible differences in students' decisions, and in male and female students' decisions to enroll in elective science courses in high versus low paradigmatic learning cycle classrooms; (b) describe patterns and examine possible differences in male and female students' attitudinal perceptions of science in the two course contexts; (c) investigate possible differences in students' science perceptions according to their decisions to enroll in elective science courses, participation in high versus low paradigmatic learning cycle classrooms, and the interaction between these two variables; and (d) examine students' explanations of their decisions to enroll or not enroll in elective science courses. Questionnaire and observation data were collected from 119 students in the classrooms of six learning cycle biology teachers. Results indicated that in classrooms where teachers most closely adhered to the ideal learning cycle, students had more positive attitudes than those in classrooms where teachers deviated from the ideal model. Significantly more females in high paradigmatic learning cycle classrooms planned to continue taking science course work compared with females in low paradigmatic learning cycle classrooms. Male students in low paradigmatic learning cycle classrooms had more negative perceptions of science compared with males in high paradigmatic classrooms, and in some cases, with all female students. It appears that using the model as it was originally designed may lead to more positive attitudes and persistence in science among students. Implications include the need for science educators to help teachers gain more thorough understanding of the learning cycle and its theoretical underpinnings so they may better implement this procedure in classroom teaching. © 2001 John Wiley & Sons, Inc.

Picturebook discussions are commonplace literacy events in contemporary classrooms. The different experiences, backgrounds and ways of being that individual students draw upon during talk around texts prompt a broad range of ways to make, negotiate and share meanings. In addition to developing students' literacy skills such as oral language, vocabulary and comprehension, these discussions have been shown to be instrumental in developing students' interpretive competence which is important for achieving learning outcomes. In this article, we report a study that investigated how four diverse groups of 10‐ and 11‐year‐old students and teachers from two schools experienced such reading events. The study found that making sense of these books was more productive when students were given permission to switch identities and make connections to their out‐of‐school cyber and popular culture worlds. Using discourse analytic techniques, we uncover the identity work during a number of discussions around two different picturebooks and show how this enabled these learners to enter the academic space and demonstrate interpretive competence.  相似文献
