Research on learning and instruction of science has shown that learning environments applied in preschool and primary school rarely makes use of structured learning materials in problem-based environments although these are decisive quality features for promoting conceptual change and scientific reasoning within early science learning. We thus developed and implemented a science learning environment for children in the first years of schooling which contains structured learning materials with the goal of supporting conceptual change concerning the understanding of the floating and sinking of objects and fostering students' scientific reasoning skills. In the present implementation study, we aim to provide a best-practice example of early science learning. The study was conducted with a sample of 15 classes of the first years of schooling and a total of 244 children. Tests were constructed to measure children's conceptual understanding before and after the implementation. Our results reveal a decrease in children's misconceptions from pretest to posttest. After the curriculum, the children were able to produce significantly more correct predictions about the sinking or floating of objects than before the curriculum and also relative to a control group. Moreover, due to the intervention, the explanations given for their predictions implied a more elaborated concept of material kinds. All in all, a well-structured curriculum promoting comparison and scientific reasoning by means of inquiry learning was shown to support children's conceptual change.  相似文献

Thought experiments (TEs) play a central role in physics. Wesuggest that erroneous TEs may be as important as correct TEs,and that both have a special role in an ongoing process ofconceptual refinement for physicists and for naive physicslearners. We analyze TEs related to stellar evolution andgeneral relativity made by Schwarzschild, Eddington, Landau,and Einstein. We identify the stages at which crucial errorsare done in these TEs, and the cognitive processes which leadto these errors. We argue that necessary conditions for asuccessful TE (i.e., a TE which leads to correct conclusions)are self-consistency and comprehensiveness of the relevantpicture of the world. We show that the TEs by expert physicistsand TEs by students are similar on a metacognitive level, butdifferent in details. Students' erroneous reasoning occur inall stages of a TE, whereas physicists usually make errors inthe first two stages of TEs. Then we bring evidence that Tesare more prone to errors than laboratory experiments. Next wediscuss the implications for naive physics learners, and makesuggestion for using TEs in physics education.  相似文献

This short report identifies the academic and environmental experiences that support the reclaiming of students at high academic risk and describes an applicable school‐wide programme emanating from the call for educational change in Israel. The proposed structured academic programme demonstrates how schools can achieve broad student knowledge and set high performance standards while accommodating diverse student needs. As such, the programme provides school practitioners with intervention targets that promote school engagement and higher school performance. In addition, the report provides illustrative examples of the implemented programme within schools for students at high academic risk in Israel. It is argued that a movement towards an adaptive model of schooling as portrayed within the structured academic programme may prove to be effective in academically engaging students at academic risk, thus providing all students with democratic possibilities for learning and knowing.  相似文献

This study explored the abilities of 5th, 8th, and 10th graders, and College students to reason logically about what they read. Both students’ metacognitive behavior (looking back at previously read text) and their performance on logical deduction questions were recorded and analyzed in a reading task. Conditional logic premises and deductive questions were embedded in three narratives containing premise information that was factual (True Story), contrary to fact (False Story), or unverifiable via common world knowledge (Neutral Story). The texts and questions were presented one sentence at a time on a computer screen; participants controlled the presentation of sentences. For answering the questions, three response tasks were devised. One task (labeled Generate) required readers to generate their own logical conclusions in response to deduction questions. Two tasks (labeled Valid and Invalid) required readers to evaluate logically valid or logically invalid conclusions drawn by story characters in the texts. Students in early and late adolescence looked back more when asked to evaluate logical conclusions than when asked to generate conclusions on their own; College students’ lookback frequencies were not significantly affected by response task, but were greater overall than those of younger students. With conditional forms requiring an uncertainty response (Affirmed Consequent and Denied Antecedent), readers looked back more when evaluating logically invalid conclusions than when evaluating logically valid ones. Readers of all ages were more likely to agree with story characters’ (valid) uncertain conclusions with the AC and DA forms than they were to disagree with story characters’ (invalid) certain conclusions to these forms. Both lookback frequency and performance on logic questions were lowest when readers were required to reason from contrary to fact premises.  相似文献

This study examines changes in teachers’ thinking as they participated in a video club designed to help them learn to notice and interpret students’ mathematical thinking. First, we investigate changes in teachers’ talk about classroom video segments before and after participation in the video club. Second, we identify three paths along which teachers learned to notice students’ mathematical thinking in this context: Direct, Cyclical, and Incremental. Finally, we explore ways the video club context influenced teacher learning. Understanding different forms of teacher learning provides insight for research on teacher cognition and may inform the design of video-based professional development.  相似文献

Attachment has been assessed in the extreme environment of orphanages, but an important issue to be addressed in this chapter is whether in addition to standard assessment procedures, such as the Strange Situation, the lack of a specific attachment in some institutionalized children should be taken into account given the limits to the development of stable relationships in institutionalized care. In addition, this chapter discusses disinhibited or indiscriminately friendly behavior that is often seen in institutionalized children. Enhanced caregiving quality alone appears to be insufficient to diminish indiscriminate behavior, at least in some children, as evidenced by the persistence of indiscriminate behavior in children adopted out of institutions into adoptive families. We suggest that the etiology and function of indiscriminate, “friendly” behavior may be different for institutionalized versus not‐institutionalized children. In the first case it may reflect a distortion or disruption of early attachment relationships; in the latter case it is likely to result from the lack of expected input in the form of contingent interactions with a stable caregiver in early life. We try to delineate infant and caregiver characteristics that are associated with secure attachment in institutional settings, given the inevitable fact that large numbers of infants worldwide are being raised, and will be raised, in contexts of institutional care. We conclude that much further study is needed of the development of children's attachments following adoption out of an institutional setting.  相似文献

Proficiency in digital literacy refers to the ability to read and write using online sources, and includes the ability to select sources relevant to the task, synthesize information into a coherent message, and communicate the message with an audience. The present study examines the determinants of digital literacy proficiency by asking 150 students who had 50 min of access to the Internet and a word processor to produce a research report on whether or not their college should require all students to own a laptop computer. The resulting essay received a holistic rating from 1 to 5. Concerning knowledge underlying digital literacy, the major predictors of digital literacy proficiency (as measured by essay rating) were academic experience (undergraduate versus graduate status) and domain knowledge (based on a questionnaire), rather than technical knowledge about how to use computers (based on a questionnaire). Concerning processing during the task, the major predictors of digital literacy proficiency were integrating processes (such as number of unique sources, citations, or supporting details) rather than search processes (such as number of actions, web pages, websites, links, or search terms). In short, proficiency in digital literacy depended mainly on academic experience rather than technical experience, and on how learners organize and integrate the information they find rather than on how much information they peruse. Findings from this study suggest that the basic tenets of good scholarship apply to digital media.  相似文献

ABSTRACT

The increased use of quantitative education data is often regarded by scholars as evidence of the emergence of’governing by numbers’. These scholars ascribe major stakeholders such as the OECD and nation states agency as they produce, distribute and consume data, and respond to these with policy and management initiatives. This paper argues that metrics themselves have a configurative agency that affects education in terms of educational ideas and designs. The paper illustrates this point by analysing two cases of graduate employability metrics, each of which configures education differently, and discusses how the configurative agency of metrics can become the focal point of a different research agenda using distinct analytical concepts drawn from the sociology of quantification and new materialism. The paper concludes that such a research agenda can enable actors involved in the design and development of education to enter into a professional dialogue and engagement with education data, rather than merely dismissing it.  相似文献

OBJECTIVE: This exploratory study examines the reported dating violence and its association with sexual risk behavior among Israeli adolescents, who are at risk for dropping out of school. METHODOLOGY: A convenience sample of 105 at-risk youth (51 boys and 54 girls) completed self-administered anonymous, questionnaires in small same-gender groups. The questionnaire included a Hebrew version of the Conflict in Adolescent Dating Relationships Inventory, a valid scale developed in the US especially for adolescents, the Hebrew version of the Conflict Tactics Scale and the Self-Efficacy to Refuse Sexual Behavior Scale. RESULTS: We found high rates of perpetration of verbal-emotional abuse for both girls and boys. Rates of reported victimization by physical abuse were higher among boys but that by sexual abuse were higher among girls. We found a moderate inverse association between victimization by dating violence and practicing safe sex among girls. There was a similar but much stronger association for boys who were victims of dating violence. CONCLUSIONS: The high rates of various types of dating violence in Israel, at least among at-risk adolescents, should raise concern and motivate designing and implementing specific prevention interventions. The high reported rates of victimization from dating violence among boys are somewhat surprising and call for special attention and more indepth studies.  相似文献
