In recent years, science education has placed increasing importance on learners' mastery of scientific reasoning. This growing emphasis presents a challenge for both developers and users of assessments. We report on our effort around the conceptualization, development, and testing the validity of an assessment of students' ability to reason around physical dynamic models in Earth Science. Building from the research literature on analogical mapping and informed by the current perspectives on learning progressions, we present a three‐tiered construct describing the increasing sophistication of students' analogical reasoning around the correspondences and non‐correspondences between models and the Earth System: at the level of entities (Level 1), configurations in space or relative motion of entities (Level 2), and the mechanism or cause for observed phenomena (Level 3). Grounded in a construct‐centered design approach, we describe our process for developing assessments in order to examine and validate this construct, including how we selected topics and models, designed items, and developed outcome spaces. We present the specific example of one assessment centered on moon phases, which was administered to 164 8th and 9th grade Earth Science students as a pre/postmeasure. Two hundred ninety‐four responses were analyzed using a Rasch modeling approach. Item difficulties and student proficiency scores were calculated and analyzed regarding their relative performance with respect to the three levels of the construct. The analysis results provided initial evidence in support of the construct as conceived, with students displaying a range of analogical reasoning spanning all three construct levels. It also identified problematic items that merit further examination. Overall, the assessment has provided us the opportunity to better describe and frame the cognitive uses of models by students during learning situations in Earth Science. Implications for instruction and future directions for research in this area are discussed. © 2012 Wiley Periodicals, Inc. J Res Sci Teach 49: 713–743, 2012  相似文献

Research on young children's reasoning show the complex relationships of knowledge, theories, and evidence in their decision-making and problem solving. Most of the research on children's reasoning skills has been done in individualized and formal research settings, not collective classroom environments where children often engage in learning and reasoning together to solve classroom problems. This study posits children's reasoning as a collective social activity that can occur in science classrooms. The study examined how children process their reasoning within the context of Grade 2/3 science classrooms and how the process of collectivity emerges from classroom interactions and dialogue between children as they attempt to solve their classroom problems. The study findings suggest that children's reasoning involves active evaluation of theories and evidence through collective problem solving, with consensus being developed through dialogical reasoning.  相似文献

We examine characteristics of classroom contexts that influence motivations for reading. We frame the discussion in terms of design principles. First, we propose several general criteria that a set of design principles should meet if the set is to be sufficient to increase long-term motivations for reading. Next, we propose 8 principles derived from research on motivational and cognitive processes, instructional research, and classroom innovations. These design principles relate to (a) conceptual themes, (b) real-world interactions, (c) self-direction, (d) interesting texts, (e) social collaboration, (f) self-expression, (g) cognitive strategy instruction, and (h) curricular coherence. We constructed these design principles from sets of design principles offered by psychologists and educators, our studies, and a literature review we conducted. In particular, we note problems of underspecification typical of psychologists' proposed sets of principles and problems of overspecification typical of educators' designs. We conclude with suggestions for needed research on classroom contexts for increasing students' motivations for reading.  相似文献

Despite compelling evidence that analogy skills are available to beginning readers, few studies have actually explored the possibility of identifying individual differences in young children's analogy skills in early reading. The present study examined individual differences in children's use of orthographic and phonological relations between words as they learn to read. Specifically, the study addressed whether general analogical reasoning, short‐term memory and domain‐specific reading skills explain 5‐ to 6‐year‐olds' reading analogies (n=51). The findings revealed an orthographic analogy effect accompanied by high levels of phonological priming. Single‐word reading and use of visual analogies predicted young children's orthographic and phonological analogies in the regression analyses. However, different findings emerged from exploring profiles based on individual differences in reasoning skill. Indeed, when individual differences in composite scores of orthographic and phonological analogy were examined, group membership was predicted by word reading and early phonological knowledge, rather than general analogical reasoning skills. The findings highlight the usefulness of exploring individual differences in children's analogy development in the early stages of learning to read.  相似文献

We report a case study of model‐based reasoning in which a small group of fourth‐grade students analyzes the energy flow when a solar panel is used to power an electric motor that spins a propeller. In developing their explanation of energy flow, the students draw on a general model of energy developed collectively by their class in the course of an experimental classroom curriculum led by a trained teacher. They also construct a model‐based representation of the specific system under study. Their investigation and reasoning process exhibit all the features of authentic scientific model‐based inquiry, including the revision of their models to incorporate new information. In the course of their work the students recruit and seamlessly integrate nearly all of the practices of science designated in the Next Generation Science Standards. This case study provides an example of what modeling‐based teaching and learning can look like in an elementary school classroom. It also suggests that the study of energy offers a particularly promising context for developing students' use of science practices, especially the practice of developing and using models.  相似文献

There is an increasing emphasis in mathematics education on the importance of estimation abilities in children. This study investigates the role of context upon primary‐aged children's estimation skills. Children in three age groups (from aged 5 to 8 years) were asked to carry out a range of estimation tasks involving distance, area and volume measurements. The tasks varied in type and complexity and were either of a ‘real‐world’ or ‘mathematics task’ form. In addition to performance measures the children's answers to questions on how they carried out the estimates were recorded and analysed. Quantitative and qualitative analyses found significant effects for context and child strategy. Estimates in contexts perceived as mathematical were different, both in that they changed with age and in their error patterns, from contexts involving perceptual‐motor skills. The children's answers highlight the importance of imagery and classroom experience. The results are discussed within a model of estimating.  相似文献

Peer collaboration can be a useful tool in a school classroom to help students perform at their best. With whom should students be paired, though? Previous research yields inconsistent findings regarding whether the benefits of peer collaboration depend on the gender or friendship of collaborators. We paired students with a same‐gender friend or a nonfriend in their classroom to examine whether friendship and specific dimensions of relationship quality were important for understanding adolescent (N = 132 high‐school students) boys' and girls' performance on a scientific reasoning task. Dimensions of relationship quality were related to task performance with greater perceived conflict predicting poorer performance. Girls outperformed boys, but the difference was marginal and nonsignificant after accounting for dimensions of relationship quality. Friends' and nonfriends' performance was similar. Results are informative for educators who use collaboration as an instructional technique and for other professionals who work to support the development of effective reasoning and problem‐solving skills among adolescents. © 2008 Wiley Periodicals, Inc.  相似文献

Setting examination questions in real‐world contexts is widespread. However, when students are reading contextualized questions there is a risk that the cognitive processes provoked by the context can interfere with their understanding of the concepts in the question. Validity may then be compromised. We introduce the concept of focus: a question in a given context is focused to the extent that it addresses the aspects of the context that will be most salient in real life for the students being tested. A more focused context will then help activate relevant concepts, rather than interfering with comprehension and reasoning. In this study, the contexts of questions from a science test for 14‐year‐olds in England were manipulated to increase or decrease the amount of focus. In every instance more focused questions proved better than less focused ones. With additional evidence from interview protocols, we also consider the effects of context focus on the question answering process.  相似文献

Children's developing reasoning skills are better understood within the context of their social and cultural lives. As part of a research–museum partnership, this article reports a study exploring science‐relevant conversations of 82 families, with children between 3 and 11 years, while visiting a children's museum exhibit about mammoth bones, and in a focused one‐on‐one exploration of a “mystery object.” Parents' use of a variety of types of science talk predicted children's conceptual engagement in the exhibit, but interestingly, different types of parent talk predicted children's engagement depending on the order of the two activities. The findings illustrate the importance of studying children's thinking in real‐world contexts and inform creation of effective real‐world science experiences for children and families.  相似文献

Learning to teach is a difficult and challenging process for beginning teachers in the national curriculum contexts due to several pressures that the centralised system presents for school and classroom contexts. This study investigated the difficulties beginning middle school mathematics teachers faced in the Turkish national curriculum context without any structured beginning teacher support through the experiences of six beginning teachers. They were interviewed after their first year teaching and after the fourth year or during the fifth year about factors in the national curriculum, school, and classroom contexts that affected their learning to teach. Findings revealed that the national curriculum context interfered with the school and classroom contexts, often by presenting many additional difficulties. The teacher education period seemed to be ineffective in preparing beginning teachers for the difficulties arising from the national curriculum context. Teacher education programmes in centralised systems should provide pre‐service teachers with knowledge of possible difficulties specific to these contexts that they might face in their first years.  相似文献

Worldwide, a tendency is visible in which upper secondary science curricula are innovated in the direction of context‐based education. Crucial to these innovations is the way teachers interact with newly developed teaching materials and implement them in classroom practice. The focus of our research is to identify characteristics of the interaction between innovative context‐based materials and teachers that hinder or facilitate classroom implementation as intended by the designers. Four cases of classroom implementation by four experienced teachers with different degrees of experiences in context‐based education, all implementing ‘Chemie im Kontext’ (CHiK) teaching materials, were carried out using a previously developed framework for analysis. It was found that a crucial aspect of CHiK, that of taking students' questions and using them as an orientation as the ‘focal event’ for the following lessons, was difficult to implement. The employed contexts are too general and broad to be effectively applicable as a setting in which activities such as students developing their own ideas and exploring them logically take place. Therefore, it is recommended that extensive teacher professionalization is required on this aspect to show teachers its value and to increase their repertoire of necessary teaching activities.  相似文献

In science education, students should come to understand the nature and significance of models. In the case of chemistry education it is argued that the present use of models is often not meaningful from the students' perspective. A strategy to overcome this problem is to use an authentic chemical modelling practice as a context for a curriculum unit. The theoretical framework for this strategy is activity theory rooted in socio‐cultural theories on learning. An authentic chemical modelling practice is characterized by a set of motives for model development through a well‐defined modelling procedure using only relevant issue knowledge. The aim of this study was to explore, analyse, and select authentic chemical modelling practices for use in chemistry education. The suitability of the practices was reviewed by applying a stepwise procedure focused on criteria such as students' interest and ownership, modelling procedure, issue knowledge, and feasibility of the laboratory work in the classroom. It was concluded that modelling drinking‐water treatment and human exposure assessment are both suitable to serve as contexts, because both practices exhibit clear motives for model construction and the applied modelling procedures are in line with students' pre‐existing procedural modelling knowledge. The issue knowledge involved is consistent with present Dutch science curriculum, and it is possible to carry out experimental work in the classroom for model calibration and validation. The method described here to select and evaluate practices for use as contexts in chemistry education can also be used in other science domains.  相似文献

Empirical evidence has attested to the benefits of autonomy support in a classroom context, in facilitating students' autonomous motivation, well-being, creativity, engagement, and persistence. However, most interventional research aiming to increase teachers' autonomy-supportive behaviors has been conducted in school and college contexts, with few studies aimed at university tutors. The current study implemented a brief theory-driven autonomy-supportive intervention in university seminars and developed an observational checklist instrument to assess behavior change. Tutors who received brief training in autonomy-supportive teaching techniques showed significant increases from baseline in two important autonomy-supportive behaviors in their classes. Potential implications and suggestions for further development of the intervention are discussed.  相似文献

Science includes more than just concepts and facts, but also encompasses scientific ways of thinking and reasoning. Students' cultural and linguistic backgrounds influence the knowledge they bring to the classroom, which impacts their degree of comfort with scientific practices. Consequently, the goal of this study was to investigate 5th grade students' views of explanation, argument, and evidence across three contexts—what scientists do, what happens in science classrooms, and what happens in everyday life. The study also focused on how students' abilities to engage in one practice, argumentation, changed over the school year. Multiple data sources were analyzed: pre‐ and post‐student interviews, videotapes of classroom instruction, and student writing. The results from the beginning of the school year suggest that students' views of explanation, argument, and evidence, varied across the three contexts with students most likely to respond “I don't know” when talking about their science classroom. Students had resources to draw from both in their everyday knowledge and knowledge of scientists, but were unclear how to use those resources in their science classroom. Students' understandings of explanation, argument, and evidence for scientists and for science class changed over the course of the school year, while their everyday meanings remained more constant. This suggests that instruction can support students in developing stronger understanding of these scientific practices, while still maintaining distinct understandings for their everyday lives. Finally, the students wrote stronger scientific arguments by the end of the school year in terms of the structure of an argument, though the accuracy, appropriateness, and sufficiency of the arguments varied depending on the specific learning or assessment task. This indicates that elementary students are able to write scientific arguments, yet they need support to apply this practice to new and more complex contexts and content areas. © 2011 Wiley Periodicals, Inc.

This investigation examined the efficacy of a verbal scaffolding instructional program designed to teach young children how to use private speech while working on school tasks and problems. Two different contexts for solving problems were used; common school tasks and analogical reasoning problems. Thirty-four 5-year olds who attended public school kindergartens were assigned to either the comparison group or the treatment group. Comparison group subjects were presented with a series of 8 lessons which focused on a cognitive strategy to be used in the solutions of geometric analogy problems. Treatment group subjects were presented with a series of 8 lessons which employed cognitive self-instruction in a verbal scaffolding format. After initial instruction using self-verbalizations, treatment group subjects were shown how to apply the cognitive self-instruction to routine school tasks and geometric analogy problems. The data analysis revealed that there was an effect on the treatment group's use of 3 of the 4 levels of private speech. When the two groups were compared, the treatment group used significantly less task irrelevant private speech and significantly more task relevant private speech. There were no significant differences between the two groups on the post-assessment of geometric analogy reasoning. Additionally, when the two groups were compared there were positive effects of the instructional program on the treatment group's classroom behavior (near transfer) and locus of control scores (far transfer). The results of this study provide support for the use of cognitive self-instruction to improve young children's problem-solving private speech in the context of a public school classroom.Portions of this paper were presented at the 2nd Annual European Congress of Psychology, Budapest Hungary, July 1991 by the first author.This paper was presented at the 1993 annual meeting of the American Educational Research Association, Atlanta, GA.  相似文献

A poetry workshop can present opportunities to integrate students' knowledge and perspectives in classroom contexts, encouraging the use of language for expression, communication, learning and even empowerment. This paper describes how adolescent students respond to a poetry workshop in an English classroom centred on teaching writing that is based on their knowledge from their various life experiences and understanding of events beyond the classroom. Informed by New Literacy Studies and third space theories, ethnographic methods of participant observation were used to document an eighth‐grade urban public school classroom where a community member implemented a weekly programme using music lyrics and poetry for an entire school year. Findings illustrate how the poetry workshop encouraged students to contribute to the classroom learning context and engage critically with ideas that were relevant to their lives. Collaborating with a community member and tapping in to the powerful ways of using language to communicate led to important learning opportunities for students in this classroom. Poetic devices such as rhyme, rhythm, metaphor and wordplay enhanced and supported students' own language practices; students used these sophisticated writing strategies as they worked to convey their ideas, experiences and opinions.  相似文献

Children's judgments about inclusion and exclusion of children with disabilities were investigated in a Swiss sample of 6‐, 9‐, and 12‐year‐old children from inclusive and noninclusive classrooms (N = 422). Overall, the majority of children judged it as morally wrong to exclude children with disabilities. Yet, participants were less likely to expect the inclusion of children with mental or physical disabilities in academic and athletic contexts compared to social contexts. Moreover, older children more consistently coordinated disability type with context of exclusion. There were also significant differences depending on the type of classroom. The findings extend existing research on exclusion by investigating exclusion based on disability across different age groups and educational settings.  相似文献

In the context of growing awareness of young children's capabilities, and debates about the nature of their reasoning in science, this study set out to explore the ways in which reception children make sense of classroom experiences in science. A particular challenge of the study was to develop appropriate and productive approaches to investigating young children's developing thinking. The first phase of research, reported in this paper, concentrated on the topic of electricity. A series of case studies was undertaken to examine children's learning in a classroom context. Classroom sessions were video recorded and transcribed to examine the development of children's practical competence in circuit making, and interviews were carried out to elicit children's views about electric circuits. Analysis of the classroom sessions revealed children's growing competence in circuit making through their self‐directed efforts. The interviews prompted predictions and explanations that were not offered spontaneously. Responses indicated a range of models of the circuit and forms of explanation for what was happening in the circuit. The relationship between children's practical competence, predictions and explanations was not straightforward. Analysis revealed marked differences in models of the circuit and forms of explanation in children with the same levels of practical competence. This has important implications for the ways in which children's views are assessed.  相似文献

This article discusses an intervention project by means of motivational approaches in a British culture survey course for English majors in mainland China's university classroom context. The intervention uses such motivational theories as attribution and task orientation to motivate the teaching and learning of the EFL course so as to create a cooperative classroom environment. Theoretical bases of the Chinese heritage culture and motivation are examined, specific intervention procedures discussed, relevant data analysed and finally some suggestions regarding the EFL teachers' important role in promoting the quality of EFL education are made. The intervention results show that an innovative pedagogy to motivate students' metacognitive awareness, cognitive and socio‐cognitive ability in cooperative classroom learning situations different from the traditional cramming methods and examinations proves effective. Motivation should be given a central role in promoting China's EFL quality education.  相似文献
