The aim of the present study is to explore the effects of Meta‐strategic Knowledge (MSK) on scientific inquiry learning. MSK is a subcomponent of metacognition defined as general, explicit knowledge about thinking strategies. Following earlier studies that showed considerable effects of explicit instruction of MSK regarding the strategy of variables control, the present study explores whether similar effects are found in two additional scientific thinking strategies: Define Research Questions and Formulate Research Hypotheses. Participants were 119 eighth‐grade students from six classes of a heterogeneous school. Equal numbers of low‐achieving and high‐achieving students were randomly assigned into experimental and control groups. The findings showed dramatic developments in students’ performance following instruction. The effect of the treatment was preserved in a delayed transfer test. Our findings show that explicit teaching of MSK had a stronger effect for low‐achieving students than for high‐achieving students. The implications of the findings for teaching and learning in the context of scientific inquiry are discussed. 相似文献

The present research explored how mothers’ own childhood experiences are linked to their perceptions of their children's sleep regulation. It focused on collective sleeping; a practice used in the past in the Israeli kibbutz, and used a quasi-experimental research design to examine whether mothers who were raised in collective sleeping arrangements differed from mothers who were raised in home sleeping. Two typically developing cohorts: infants (n = 68; ages 9–15 months; M = 12.2, SD = 2.2) and preschool children (n = 113; ages 48–55 months; M = 51.5, SD = 1.85) participated in this investigation. Sleep regulation and temperament were reported for infants and children, whereas for mothers data were collected on separation anxiety and appraisal of the ecology in which they were raised. Collectively raised mothers evaluated their upbringing significantly more negatively than home-raised mothers, expressed higher separation anxiety with regard to an alternative caregiver, but were not different in their views of their child's sleep difficulties. For infants, it was maternal separation anxiety that contributed uniquely to the explained variance in maternal view of sleep regulation difficulties. For preschool children, it was maternal evaluation of own childhood ecology and child's temperament that contributed uniquely to the explained variance in maternal view of sleep regulation difficulties. These findings suggest that mothers’ representations of their sleep-related early experiences, rather than their childhood ecology in and of itself, influenced their perceptions about their child's sleep, which, in turn, affect child's sleep patterns. Implications to caregiving are discussed. 相似文献

The most recent science and technology curriculum for junior high school in Israel contains a new guideline stating that the
cell topic is to be taught “longitudinally in conjunction with other study contents.” This guideline confers a change in teaching
the cell topic and provides an opportunity to form meaningful relationships between biological phenomena at the macro level
and their cellular explanations. Here, we examined the extent to which six textbooks, available for junior high schools in
Israel, support this teaching approach. We found that the textbooks differ in how they express the guideline and that most
of them do not support the new teaching approach to any significant extent. Moreover, the textbooks generally emphasize cells’
structure and pay less attention to the processes occurring in them. Our findings could shed light on students’ difficulties
in comprehending the living cell and in correlating macroscopic phenomena with their cellular explanations. 相似文献

One of the central unresolved conceptual issues that concerns researchers of personal epistemology is the characterization of the intersection between personal epistemology and metacognition. The contested and diverse nature of both constructs makes untangling their connections a complex yet vital task. The purpose of this article is to advance the discussion regarding this intersection by offering a theoretical approach that may serve as a basis for analyzing epistemic thinking and aligning it with current views of metacognition. Based on a synthesis of theoretical and empirical studies, we argue that epistemic thinking is a multifaceted construct with both cognitive and metacognitive aspects. Furthermore, we propose that epistemic metacognition includes several aspects such as metacognitive skills; metacognitive knowledge about persons, strategies and tasks; and metacognitive experiences. The theoretical, methodological, and instructional implications of this approach are explored. 相似文献

The current study examined the predictive roles of L2 vocabulary knowledge and L2 word reading skills in explaining individual differences in lexical inferencing in the L2. Participants were 53 Israeli high school students who emigrated from the former Soviet Union, and spoke Russian as an L1 and Hebrew as an L2. L2 vocabulary knowledge and decoding accuracy predicted L2 reading comprehension, which in turn was strongly related to lexical inferencing abilities in the L2. In addition, decoding accuracy predicted additional variance in lexical inferencing, beyond the role of reading comprehension. These findings support the idea that beginning L2 readers with more precise and efficient lexical representations demonstrate better lexical inferencing abilities, most likely due to the increased automatization of word reading, which frees up resources for higher level processing. These results suggest that lexical inferencing from text in the L2 might be limited not only by vocabulary knowledge and higher order comprehension processes, but also by basic decoding skills. 相似文献

Reading Science Texts—Epistemology, Inquiry, Authenticity—A Rejoinder to Jonathan Osborne 总被引：1，自引：1，他引：0

We shall structure this rejoinder around two main sections. In the first, we address three underlying assumptions of our work
that Osborne has identified. We indicate points of agreement, disagreement, and clarification. In the second section, we discuss
briefly and add our clarifications to three understandings of his that Osborne introduces into the discussion. It should be
noted that Osborne’s response is grounded in the same basic assumption as our set of papers, namely, the central role played
by reading and writing, and communicative activities in general, both in science and in learning science. 相似文献
