An important question which is often overlooked addresses the nature and quantity of higher‐order thinking activities when teachers are not explicitly ‘teaching for thinking’ but rather acting and behaving routinely. This study investigates the scope and nature of tasks demanding students’ application of higher‐order thinking skills while studying biology in junior and senior high schools in Israel. The method used is the collection and analysis of questions asked by teachers during classroom discourse, in homework assignments and in tests. The main findings show: (a) that the frequency of higher‐order thinking questions in biology class discourse in Israel is approximately 20%; (b) that the cognitive level of teachers’ questioning in HS is higher than in JHS; (c) that the matriculation exam has a strong influence on tests given by teachers; and (d) that while inquiry questions permeated HS testing they are less salient in HS class discourse, indicating the need for remedial treatment which should include the integration of more inquiry‐oriented pedagogies into classroom practice. 相似文献

Due to the growth in both the number and use of e-books, the question arises as to which factors may influence information professionals and library and information science (LIS) students when considering adopting e-books in their organizations. This study uses the technology acceptance model (TAM), a well-known theory for explaining individuals' technology behaviors, and cognitive appraisal theory as theoretical bases from which to predict factors that may influence information professionals and LIS students in their adoption of e-books in their organizations. This study explored two main themes: whether there are differences between information professionals' and LIS students' perspectives towards e-books, and to what extent the TAM, as well as other personal characteristics such as threat, challenge, and motivation, explain information professionals' and LIS students' perspectives. Researchers used questionnaires to gather data on computer competence, attitudes to ebooks, motivation, and cognitive appraisal. Findings reveal that there are major differences between the two groups concerning computer competence, motivation, and challenge. In addition, the TAM, as well as other personal characteristics, can predict the likelihood of e-book adoption, and highlights the importance of individual characteristics when considering technology acceptance. 相似文献

The current research explores whether librarians, whose main work focuses on information, are familiar with new technological changes and innovations, and whether they make use of different Web 2.0 applications. The research examines whether personality characteristics (resistance to change, cognitive appraisal, empowerment and extroversion or introversion), as well as computer expertise, motivation, importance and capacity towards studying and integrating different applications of Web 2.0 in future, influence librarians' use of Web 2.0. Different questionnaires were distributed to 168 randomly Israeli librarians throughout the country. The research revealed that personality characteristics as well as computer expertise, motivation, importance and capacity towards studying and integrating different applications of Web 2.0 in the future, influence librarians' use of Web 2.0. These findings have theoretical as well as practical implications. 相似文献

Blogging, though a relatively new phenomenon, has already gained greatly in popularity, and blogs have become an essential information channel in the Web 2.0 information world. Research into 30 topic-oriented blogs dealing with librarianship and information science, focusing specifically on tagging and folksonomies, was conducted over a period of two months. The purpose of the analysis was to describe and classify the LIS blogosphere, with the purpose of understanding the tagging patterns of librarian and information scientist bloggers and the nature of the folksonomies they form. Findings indicate that professional LIS blogs reflect the most up-to-date interests of LIS professionals as well as bloggers' personal lives and experiences. Content analysis reveals that the tag schemes generated by users contain their own internal logic and order. 相似文献

This study was concerned with the interactive role of experience of athletic skill with other relevant environmental variables (display complexity, attentional resources, exposure time of stimuli) on perception (recall) of structured handball game situations. Nineteen experienced (older) and 19 less experienced (younger) handball players were assigned randomly either to ball‐bouncing (diverted attention) or to calm seated (focused attention) conditions. In each of the two conditions, the subjects were exposed to a total of 36 slides containing 2–3, 5–6 and 8–10 players. Eighteen slides were exposed for 0.5 s and 18 for 1.0 s. All the slides contained structured defence and offence situations. Recall scores were subjected to repeated‐measures ANOVA using attention condition and age as between‐subject factors and task complexity and exposure duration as within‐subject factors. The results showed that the recall of less experienced players deteriorated more than the recall of more experienced players following exposure to complex displays (≥ 8 players) while engaging in a secondary task (bouncing). The findings suggest that research paradigms should be applied in the field of sport which share both ecological validity and a potential to discover the cognitive substrates underlying experience and age in skilled motor performance. 相似文献

To examine the development of triplets, 23 sets of triplets were matched with 23 sets of twins and 23 singletons (N=138). Maternal sensitivity was observed at newborn, 3, 6, and 12 months, and infants' cognitive and symbolic skills at 1 year. Triplets received lower maternal sensitivity across infancy and exhibited poorer cognitive competencies compared with singletons and twins. The most medically compromised triplet showed the lowest regulation, received lower maternal sensitivity, and demonstrated the weakest outcomes compared with siblings. Structural modeling charted three levels of influence on cognitive outcomes: direct, indirect, and contextual. The triplet ecology provides a context for assessing the relations among infant inborn dispositions, the rearing environment, and the role of exclusive parenting in development. 相似文献

This article reports the development and application of two instruments for assessing science teachers’ pedagogical knowledge in the context of teaching higher‐order thinking: a Likert‐type research instrument, and an instrument that analyzes classroom observations. The rationale for developing these instruments and their main categories is described. One hundred and fifty Israeli science teachers replied to the Likert‐type questionnaire. Results show that biology teachers gained a significantly higher score than either physics or chemistry teachers, that junior high school teachers scored significantly higher than high school teachers, and that a significant negative correlation was found between final scores and teaching experience. Participants in the classroom observation study were 14 teachers who attended a one‐year professional development course for teaching higher‐order thinking. The instrument was sensitive in detecting progress in teachers’ pedagogical knowledge in several categories, such as: Frequency of tasks that required higher‐order thinking; The variety of thinking strategies that teachers addressed during their lessons; Engagement of students in metacognitive thinking; and Using the “language of thinking” in class. The implications of the findings for research and practice are described. 相似文献

There is emerging interest on the interactions between modelling and argumentation in specific contexts, such as genetics learning. It has been suggested that modelling might help students understand and argue on genetics. We propose modelling gene expression as a way to learn molecular genetics and diseases with a genetic component. The study is framed in Tiberghien’s (2000) two worlds of knowledge, the world of “theories & models” and the world of “objects & events”, adding a third component, the world of representations. We seek to examine how modelling and argumentation interact and connect the three worlds of knowledge while modelling gene expression. It is a case study of 10th graders learning about diseases with a genetic component. The research questions are as follows: (1) What argumentative and modelling operations do students enact in the process of modelling gene expression? Specifically, which operations allow connecting the three worlds of knowledge? (2) What are the interactions between modelling and argumentation in modelling gene expression? To what extent do these interactions help students connect the three worlds of knowledge and modelling gene expression? The argumentative operation of using evidence helps students to relate the three worlds of knowledge, enacted in all the connections. It seems to be a relationship among the number of interactions between modelling and argumentation, the connections between world of knowledge and students’ capacity to develop a more sophisticated representation. Despite this is a case study, this approach of analysis reveals potentialities for a deeper understanding of learning genetics though scientific practices. 相似文献

This study applies discourse analysis to Israeli media coverage of national and international standardized examinations within Israel's public education system. Through systematic analysis of the topic in the two main Israeli financial publications between the years 2000 and 2013, we explore the nature and narrative of the media and compare the coverage of national and international standardized testing. We find that most of the media attention was devoted to international examinations, while national examinations were covered in a more limited yet critical way, perceived as unnecessary and even dubious. International examinations, in contrast, were described as axiomatic components of the education system. Articles on both national and international standardized testing criticize the education system, blaming teachers, the Ministry of Education, budget constraints, and marginalized populations for Israeli students’ inadequate results. We frame our analysis by alignment of the articles along global–local and also neoliberal–humanistic axes. We structure our assessment within the global–local nexus and discuss the broader implications of the role of the testing in framing the local educational public discourse. 相似文献
