The purpose of this study is to investigate the ways in which Swedish seventh grade students (12 and 13 years old) handle chance encounters. Four groups of students working in pairs participated in the study. In the group discussions, which were tape-recorded and fully transcribed, the students were encouraged to explore strategies for winning a specifically designed dice game based on the sum of two dice. The dice game included four different set-ups of dice designed to bring to the fore different aspects of probability modelling and to offer the student the opportunity to encounter small differences in the mathematical structure of the sample space and of the probability distribution between the four different set-ups. The study describes strategies that the students use when confronted with these different set-ups, what their activities imply in terms of resources in handling random phenomena and what the dice game offers in terms of opportunities for learning probability. In order to explain such meaning-making processes the students’ activities are viewed from a perspective that takes into consideration how the students’ understanding varies with their interpretations of the situation they are confronted with, i.e., how they contextualize the different set-ups of the dice game. The results show how the students, during the course of the game, reorganize their interpretations of the mathematical content confronting them, and how a variation of guiding principles becomes the object of exploration. Approaches of extremes and a number model are described as a means for the students to identify and assign probabilities for the total of two dice.  相似文献

This study investigates Pakistan's secondary school children's constructions of their national identity in a Pakistani school in Dubai by drawing on data collected from students and teachers from the case school and analysing national curriculum textbooks used in the school. Informed by Foucault's concepts, the article problematises how the curriculum textbooks are employed as a technology of power for inculcating national consciousness in the students. The findings suggest that Pakistan's national curriculum textbooks deploy a specific version of Islam as a major technology, which then influences other national identity signifiers in the textbooks for shaping students' national identity. The school affords a crucial space for the complex interplay of these technologies, which construct students' ethnocentric national identities, encouraging social polarisation. This has implications for Pakistan's national social cohesion as well as the potential for subverting international peaceful coexistence and working relationships, particularly in the selected overseas study context.  相似文献

Abstract

This study investigates the effects on learning‐disabled students of embedding a drill and practice task within an arcade game‐like context. We identified 30 learning‐disabled and 30 nondisabled students who had conceptual understanding of addition but had not achieved automaticity in addition facts. We trained students on either a drill‐and‐practice game or an unadorned, straightforward drill (i.e., “plain vanilla") program. We assessed automaticity in three modes of responding—oral, computer keyboard, and written response. There was a significant interaction effect indicating that the learning‐disabled students were relatively disadvantaged by repeated practice in the game format. We infer learning‐disabled students' lower performance is attributed to attentional difficulties, particularly selective attention problems, when potentially distracting elements of a game environment are present.  相似文献

Students' difficulties in interpreting what counts as knowledge have been addressed in past research on science education. The implementation of progressivist pedagogy in terms of more student-active classroom practice and the introduction of a variety of discourses into the science classroom deepens students' difficulties. The integration of different forms and demands of knowledge and discourses typified by Science-in-Context initiatives, such as within the socioscientific framework, exemplifies this development in science education. Here, the diffuse boundaries between school subjects and other silos of knowledge lead to considerable difficulties for students to interpret what is expected from them. Such contexts having diffuse boundaries between, for example, subject discourses and other forms of knowledge, have been describes as contexts with weak classification. The present study aims to explore students' interpretation of what knowledge or meaning they are requested to produce in contexts with weak classification, here exemplified within an SSI-task. We use Bernstein's concepts of recognition rules and classification to analyze how 15- to 16-year-old students develop their discussions in groups of 4–6 students. This study reports how students' recognition of the educational demands enabled integration of different discourses in their discussion, and that the use of both universalistic and particularistic meanings can produce new understandings. Students who had not acquired recognition rules were found to keep discourses apart, expressed either as rejection of the relevance of the task, answering questions as in a traditional school task, or just exchange of personal opinions. Furthermore, they included discourses irrelevant to the issue. An important outcome of the study was that socioscientific thinking was hampered when students kept universalistic and particularistic meanings apart. This hampering results from the inhibition of dynamic exploration during SSI discussions. The results provide new insights with relevance for teachers' guiding students toward a fruitful SSI-discourse.  相似文献

Previous research has demonstrated the potential of examining log-file data from computer-based assessments to understand student interactions with complex inquiry tasks. Rather than solely providing information about what has been achieved or the accuracy of student responses (product data), students' log files offer additional insights into how the responses were produced (process data). In this study, we examined students' log files to detect patterns of students' interactions with computer-based assessment and to determine whether unique characteristics of these interactions emerge as distinct profiles of inquiry performance. Knowledge about the characteristics of these profiles can shed light on why some students are more successful at solving simulated inquiry tasks than others and how to support student understanding of scientific inquiry through computer-based environments. We analyzed the Norwegian PISA 2015 log-file data, science performance as well as background questionnaire (N = 1,222 students) by focusing on two inquiry tasks, which required scientific reasoning skills: coordinating the effects of multiple variables and coordinating theory and evidence. Using a mixture modeling approach, we identified three distinct profiles of students' inquiry performance: strategic, emergent, and disengaged. These profiles revealed different characteristics of students' exploration behavior, inquiry strategy, time-on-task, and item accuracy. Further analyses showed that students' assignment to these profiles varied according to their demographic characteristics (gender, socio-economic status, and language at home), attitudes (enjoyment in science, self-efficacy, and test anxiety), and science achievement. Although students' profiles on the two inquiry tasks were significantly related, we also found some variations in the proportion of students' transitions between profiles. Our study contributes to understanding how students interact with complex simulated inquiry tasks and showcases how log-file data from PISA 2015 can aid this understanding.  相似文献

Although students' affects and behaviors in achievement situations have been shown to be influenced by their previous learning experiences, less is known about how they relate to students' dispositional characteristics, such as temperament. This study examined to what extent children's temperament is related to their affective and behavioral responses in achievement situations. Teachers rated first-graders' (n = 153) temperamental characteristics in the Fall semester. Children's active task avoidance, anxiety, and helplessness were rated in test situations in the Fall and Spring semesters. The results showed that the more easily distracted the children were, the more task avoidance they showed, and the more their task avoidance increased during the first grade. Moreover, children's high level of inhibition was related to high levels of anxiety and helplessness. The findings suggest that characteristics that are related to students' behavioral regulation and inhibition are particularly important for their affective and behavioral responses in achievement situations.  相似文献

We probed the impact of two teaching strategies, guided inquiry and argumentation, on students' conceptual understanding of the conservation of matter. Conservation of matter is a central concept in middle school science curriculum and a prerequisite upon which rests more complex constructs in chemistry. The results indicate that guided inquiry was particularly effective in improving students' conceptual understanding, as evidenced by pre/posttest results and by a skill analysis of in-depth interviews of student dyads. We also discuss how the challenges inherent to educational contexts can undermine the quality and limit the impact of empirical research carried out in many schools. We suggest how these challenges could be met in the emerging infrastructures for change called the Research Schools Network.  相似文献

Abstract

This study examined how six Singapore teachers approached the design and implementation of a unit of work (topic) to demonstrate exemplary classroom practices that engage learners and use ICT in knowledge-generative rather than presentational activities. After a reflection and feedback session on the first lesson observation involving the researcher and the teacher, the teacher redesigned the lesson to enhance ICT use and involve students more actively in their learning. Our study revealed that there is a difference between students' physical engagement and cognitive engagement in a task and that the teacher, as a designer of the learning environment, needs to make explicit the cognitive processes involved in using the tool to ensure students' effective use of ICT. The teachers' understanding of what constitutes effective learning and their roles in students' learning determine how they design the learning environment. In essence, it is the teacher's skill in managing the “tripartite” partnership of IT tool, learning task, and teacher support that brings about higher levels of student engagement.  相似文献

There has been extensive investigation into factors affecting digital technology integration in learning and teaching, but the complexity of integration continues to elude understanding. Thus, questions about how digital technologies can be best used to support learning persist. This paper argues that methods designed to address complex systems are needed to understand the interplay between teaching, learning and digital technologies. Starting with a developing system model of teachers' technology integration, this study revises the model to include factors of students' experience using digital technologies and beliefs about learning. The revised model is then used to demonstrate possible effects of student experiences in a technologically integrated group learning task. Analysis draws on data from a large-scale Australian study of technology innovation (N = 7406). Data mining techniques are used to identify patterns of students' technology use and perceptions of group work. Findings inform revision of the model to include factors of students' experience and learning and their effects on teachers' practice. Implications for learning design and students' learning experiences are explored.  相似文献

Assessing the credibility of evidence in complex, socio‐scientific problems is of paramount importance. However, there is little discussion in the science education literature on this topic and on how students can be supported in developing such skills. In this article, we describe an instructional design framework, which we call the Credibility Assessment Framework, to scaffold high school students' collaborative construction of evidence‐based decisions and their assessment of the credibility of evidence. The framework was employed for the design of a web‐based reflective inquiry environment on a socio‐scientific issue, and was enacted with 11th grade students. The article describes the components of the Credibility Assessment Framework and provides the details and results of an empirical study illustrating this framework in practice. The results are presented in the form of a case study of how 11th grade students investigated and evaluated scientific data relating to the cultivation of genetically modified plants. Multiple kinds of data were collected, including pre‐ and post‐tests of students' conceptual understanding and their skills in assessing the credibility of evidence, and videotapes of students' collaborative inquiry sessions. The analysis of the pre‐ and post‐tests on students' conceptual understanding of Biotechnology and their skills in assessing the credibility of evidence revealed statistically significant learning gains. Students' work in task‐related artifacts and the analysis of two groups' videotaped discussions showed that students became sensitive to credibility criteria, questioned the sources of data and correctly identified sources of low, moderate, and high credibility. Implications for designers and educators regarding the application of this framework are discussed. © 2011 Wiley Periodicals, Inc. J Res Sci Teach 48: 711–744, 2011  相似文献

The importance of students' sense of school belonging for many adaptive outcomes is becoming well established; however, few researchers have focused on college-aged populations. In this study, the authors examined associations between undergraduate students' sense of class belonging and their academic motivation in that class, their sense of class belonging and perceptions of their instructors' characteristics, and their class and campus-level sense of belonging. They distributed questionnaires to students at a southeastern university; freshmen (N = 238) completed the questionnaire. The authors found associations between (a) students' sense of class belonging and their academic self-efficacy, intrinsic motivation, and task value; (b) students' sense of class-level belonging and their perceptions of instructors' warmth and openness, encouragement of student participation, and organization; and (c) students' sense of university-level belonging and their sense of social acceptance. The authors found smaller effects on students' sense of university-level belonging for faculty pedagogical caring and for class-level sense of belonging.  相似文献

Empirical research reveals that students face difficulties engaging in learning and achieving their goals in a variety of learning contexts. To study effectively, students need to regulate their learning process. In spite of increased understanding of cognitive aspects of self-regulation, motivational aspects of regulation have not yet been thoroughly probed. This study investigates how motivation is connected to self-regulated learning when elementary school students (N = 32) study science in real classroom contexts using gStudy software. This was done by: (1) identifying students' situated motivation during the learning process, (2) analyzing how the students with different motivational approaches activated cognitive self-regulation in authentic learning situations across multiple learning episodes, and (3) complementing the understanding with the students' individual accounts of their motivation regulation during the learning process. The results show that there are qualitative differences in the self-regulation tactics used by the high- and low-motivation students as they study. Motivation is linked closely to active self-regulation.  相似文献

Interactive engagement (IE) is a process that promotes students' conceptual understanding through activities, combined with immediate feedback from peers and/or instructors. The present study investigates the impact of IE on students' academic performance, using the comprehensive model of educational effectiveness. Engineering students (n?=?158), randomly divided into three groups (self-assessment, collaborative learning, and control) provided the study data on questionnaires as well as with their test scores. Analyses of covariance reveal significant differences across groups, along with significant interaction effects. These findings have notable implications for improving students' academic achievement.  相似文献

This study investigated how students' level of motivation and use of specific cognitive and self-regulatory strategies changed over time, and how these motivational and cognitive components in turn predicted students' course performance in chemistry. Participants were 458 students enrolled in introductory college chemistry classes. Participants' motivation and strategy use were assessed at three time points over the course of one semester using self-report instruments. Results showed an overall decline in students' motivational levels over time. There was also a decline in students' use of rehearsal and elaboration strategies over time; students' use of organizational and self-regulatory strategies increased over time. These trends, however, were found to vary by students' achievement levels. In terms of the relations of motivation and cognition to achievement, the motivational components of self-efficacy and task value were found to be the best predictors of final course performance even after controlling for prior achievement.  相似文献

Background: In England, the promotion of ‘national values’ within the history curriculum has become an increasingly topical issue in the wake of recent debates about ‘Britishness’ and community cohesion. However, despite the swathe of policy statements and pronouncements, there is little empirical evidence linking young people's identities and their attitudes towards history.

Purpose: Drawing on a survey of undergraduates, we explore young people's attitudes towards the history curriculum and how these relate to their ethnic, national and political identity. We anticipated that students ascribing to a strong sense of national identity may be particularly receptive to a traditional approach to teaching national values within history classes, while those with a strong sense of political identity would be receptive to a multicultural approach; and vice versa.

Sample: The sample consisted of 353 undergraduates attending five universities in the North of England. The sample was composed of British citizens, the majority of whom would have recently experienced secondary education including discrete or cross-curricular teaching designed to promote ‘British’ national values.

Design and methods: Students' attitudes towards history and their self-identity were estimated using a questionnaire survey asking respondents a series of questions about history teaching and identity. Exploratory factor analysis was used to reveal underlying patterns in students' responses to items assessing their attitudes towards history. Items gauging relevant dimensions of self-identification, such as the relative importance of their national identity, along with other individual background characteristics, were then regressed on to attitudes towards history.

Results: We found that students' attitudes towards history were connected with two distinct factors: traditional/conservative and multicultural/liberal. The regression results revealed a positive relationship between a strong sense of national identity and a traditional attitude towards history, and, a negative relationship between a strong sense of national identity and a multicultural attitude towards history, even when controlling for students' background characteristics.

Conclusions: Our exploratory research suggests that students' self-identity is likely to influence their attitudes towards approaches to history teaching. Educational policy-makers and practitioners must therefore pay careful attention to students' self-identity and the context in which this is formed when seeking to inculcate an inclusive national identity in history classes.  相似文献

Literature suggests that the type of context wherein a task is placed relates to students' performance and solution strategies. In the particular domain of logical thinking, there is the belief that students have less difficulty reasoning in verbal than in logically equivalent symbolic tasks. Thus far, this belief has remained relatively unexplored in the domain of teaching and learning of mathematics, and has not been examined with respect to students' major field of study. In this study, we examined the performance of 95 senior undergraduate mathematics and education majors in symbolic and verbal tasks about the contraposition equivalence rule. The selection of two different groups of participants allowed for the examination of the hypothesis that students' major may influence the relation between their performance in tasks about contraposition and the context(symbolic/verbal) wherein this is placed. The selection of contraposition equivalence rule also addressed a gap in the body of research on undergraduate students' understanding of proof by contraposition. The analysis was based on written responses of all participants to specially developed tasks and on semi-structured interviews with 11 subjects. The findings showed different variations in the performance of each of the two groups in the two contexts. while education majors performed significantly better in the verbal than in the symbolic tasks, mathematics majors' performance showed only modest variations. The results call for both major- and context- specific considerations of students' understanding of logical principles, and reveal the complexity of the system of factors that influence students' logical thinking.  相似文献

This article contains the results of how a selected group of Finnish upper secondary students understand Lutheranism. The data consisted of 63 students' responses to a writing task together with complementary interviews of 11 students. The outcomes of phenomenographic analysis of variation in the students' understanding of Lutheranism are presented in five hierarchically ordered categories. The implications for religious education are discussed in terms of what teachers could learn from differences in students' understandings of the subject matter in order to enhance their learning of it.  相似文献

Carefully scaffolded dynamic visualizations have potential to promote science learning for all students, including English language learners (ELLs) who are often underserved in mainstream science classrooms, but little is known about how to design effective scaffolding to support such diverse students' learning with dynamic visualizations. This study investigated how two forms of scaffolding embedded in dynamic visualizations, expert guidance and generating guidance, can foster ELLs' and non-ELLs' understanding of unobservable scientific phenomena. While interacting with dynamic visualizations, students in the expert guidance condition were provided with scientifically accurate explanations to interpret visual representations, whereas students in the generating guidance condition were prompted to generate their own explanations using visual representations. The results show the significant advantage of generating guidance over expert guidance for both ELLs and non-ELLs, although students in the generating guidance condition did not receive feedback on their generated artifacts. Analyses of video data and log data from 40 pairs revealed that each form of scaffolding affected the quantity and quality of linguistically diverse students' conversations. The results show that generating guidance enabled students, particularly ELLs, to engage in discourse-rich practices to evaluate various sources of evidence from the visualization and compare the evidence to their alternative ideas to develop a coherent understanding of the target concepts. This study shows the unique benefits of generating guidance as an effective strategy to support linguistically diverse students' science learning with dynamic visualizations.  相似文献

This article introduces the cognitive affective engagement model (CAEM) of multiple source use. The CAEM is presented as a way of unifying cognitive and behaviorally focused models of multiple text engagement with research on the role of affective factors (e.g., interest) in text processing. The CAEM proposes that students' engagement with multiple texts may be explained by the default stance toward task completion they adopt. Students' default stances are defined according to two dimensions: their level of affective engagement with the topic of the task and their habits with regard to text evaluation. Default stances are used to explain a host of multiple text use behaviors, such as text selection, duration of text access, and document information access, and performance outcomes, including text recall and integration. Directions for future research on the CAEM are proposed.  相似文献
