Qualitative changes in intuitive biology 总被引:1,自引:0,他引:1
Recent studies on children’s intuitive biology have indicated that a form of autonomous biology is acquired early in childhood and that later qualitative changes occur within the domain. In this article we focus on two of such changes: (a) In predicting behaviors and attributing properties to an animate object, young children rely on the target’s similarity to people, whereas older children and adults use its category membership and category-behavior (or property) associations; and (b) The modes of explanation change from vitalistic to mechanistic. Whereas young children prefer vitalistic explanations, older children and adults like mechanistic explanations better. We present some experimental findings for these changes. We also indicate how social contexts induce or enhance conceptual change. We discuss three theo-retical issues: implications for conceptual change in biology, for conceptual change in general, and for biology instruction. 相似文献

The present study examined the effectiveness of video hero modelling and praising (VHMP), which has been proved as effective in behaviour change for students with autism spectrum disorders (ASD), in improving the transition-related behaviours of two elementary-aged students with Down Syndrome (DS). Each participant watched a video in which she exhibited appropriate transition-related behaviours side by side with her hero in the setting where the target behaviours were expected to occur. In addition, the hero praised the student for exhibiting the target behaviours in the video. A multiple-baseline-across-settings design was utilised for one student and an AB design for the other to determine if VHMP contributed to their behaviour change. Results showed that their transition-related behaviours dramatically improved immediately after VHMP was introduced. These findings imply that VHMP can be applied to behaviour change not only for students with ASD but also for those with DS. 相似文献

A word problem that requires addition of fractions with different denominators was presented to 11 classes of 4th- or 5th-graders, 10 years of age. It had three answer alternatives: adding the denominators and numerators separately, transforming fractions into decimals before adding them, and the standard, most appropriate solution. Students in each class were required to choose an alternative themselves, state their reason for the choice, and discuss which alternative would be right. After whole-class discussion, they were asked to choose an alternative again and nominate the student who had offered the most plausible idea. Then students in six classes were informed which alternative was the most appropriate, whereas those in five classes were not. Finally, the students, irrespective of the presence/absence of feedback, were required to solve the initial problem without the alternatives as the post-test, and two new problems as the transfer test.The results showed that (a) the students could offer more or less plausible arguments for or against each alternative, which in most classes included the correct explanation; (b) both vocal and silent students could write a mathematical expression for the post-test problem and manipulated it correctly, incorporating other students' ideas presented during the discussion, with or without the teacher's feedback, though their generalization was rather limited; and (c) the students could recognize and memorize reasonable explanations offered by other students in the discussion. 相似文献

This study aimed to examine the relations between educational and interpersonal identity trajectories and psychosocial functioning based on a three-factor identity process model. A total of 968 Japanese adolescents including 13- and 16-years-olds (49.7% female) participated in a four-wave longitudinal study. Latent class growth analysis extracted five identity trajectories in each educational and interpersonal identity domain and revealed (a) high prevalence of low commitment identity trajectories, (b) absence of the closure trajectory, and (c) changeable identity trajectories that have not been identified in Western context (i.e., the Netherlands). Furthermore, a latent change model revealed dynamic relations between identity trajectories and psychosocial functioning. These findings provide critical insights into the diverse and dynamic pathways of identity formation during adolescence in Japan. 相似文献

Young Children's Understanding of the Mind-Body Distinction 总被引:3,自引:0,他引:3
4 experiments investigated children's understanding of the mind-body distinction. Children of ages 4 and 5 recognized not only the differential modifiability of changeable versus unchangeable human properties and bodily versus mental properties, but also the independence of activities of bodily organs from a person's intention (Experiment 1). When presented 3 types of causal explanations (i.e., intentional, vitalistic, mechanical), 6-year-olds chose most often as most plausible for bodily functions vitalistic explanations (i.e., those ascribing the phenomena to a relevant bodily organ's initiative and effortful engagement in activity); 8-year-olds chose the vitalistic explanations second most often, following mechanical ones (Experiment 2). However, 6-year-olds, as well as 8-year-olds and adults, did not always choose vitalistic explanations over intentional explanations (Experiment 3); whereas they tended to prefer vitalistic explanations for biological phenomena, they predominantly accepted intentional ones for psychological phenomena (Experiment 3A). These results suggest that children as young as 6 years of age have acquired a form of biology as an autonomous domain which is separate from that of psychology. 相似文献
