This study investigated the effects of presenting domain information (basic information about the domain) either together with or instead of offering exploratory practice (an exploratory opportunity in a simulation-based representation of the learning domain) prior to inquiry learning for facilitating students' hypothesis generation and subsequent inquiry processes and their knowledge acquisition. Secondary school students (n = 118) completed a simulation-based inquiry task on force and motion. They were randomly assigned to one of four conditions: the D + E condition (n = 29), in which domain information and exploratory practice were available; the D condition (n = 30), in which only domain information was available; the E condition (n = 32), in which only exploratory practice was available; or the C condition (n = 27), with no support at all. Students' knowledge was measured with a pre- and posttest and a test on knowledge of variables. Inquiry processes were inferred from information students entered in a Hypothesis Scratchpad and an Observation tool, and from a final summary that they had to write. Results indicated that providing students with domain information alone helps to foster their knowledge of variables before generating hypotheses and leads to knowledge acquisition. The results also showed that the opportunity to explore before experimenting does not affect students' inquiry behavior or learning performance, even when combined with providing students with domain information. 相似文献

It is known that the incidence of bullying reported by primary school children varies greatly between schools. It has also been shown that schools in which staff express a greater level of concern with managing the problem generally experience lower levels of bullying. This study examines the children’s, rather than the teachers’, views about the level of care and attention which the teachers pay to issues relating to behaviour and the social organisation of their school. It is shown that the children’s views are a good indicator of the frequency of bullying that will be found in that school. 相似文献

Assisting self-explanation prompts are more effective than open prompts when learning with multiple representations 总被引：1，自引：0，他引：1
Learning with multiple representations is usually employed in order to foster understanding. However, it also imposes high
demands on the learners and often does not lead to the expected results, especially because the learners do not integrate
the different representations. Thus, it is necessary to support the learners’ self-explanation activity, which concerns the
integration and understanding of multiple representations. In the present experiment, we employed multi-representational worked-out
examples and tested the effects of two types of self-explanation prompts as help procedures for integrating and understanding
multiple representations. The participants (N = 62) learned about probability theory under three conditions: (a) open self-explanation prompts, (b) self-explanation prompts
in an assistance-giving-assistance-withholding procedure (assisting self-explanation prompts), or (c) no prompts (control
group). Both types of self-explanation prompts fostered procedural knowledge. This effect was mediated by self-explanations
directed to domain principles. Conceptual knowledge was particularly fostered by assisting self-explanation prompts which
was mediated by self-explanations on the rationale of a principle. Thus, for enhancing high-quality self-explanations and
both procedural knowledge and conceptual understanding, we conclude that assisting self-explanation prompts should be provided.
We call this the assisting self-explanation prompt effect which refers to the elicitation of high-quality self-explanations and the acquisition of deep understanding. 相似文献

Students in introductory biology courses frequently have misconceptions regarding natural selection. In this paper, we describe six activities that biology instructors can use to teach undergraduate students in introductory biology courses how natural selection causes evolution. These activities begin with a lesson introducing students to natural selection and also include discussions on sexual selection, molecular evolution, evolution of complex traits, and the evolution of behavior. The set of six topics gives students the opportunity to see how natural selection operates in a variety of contexts. Pre- and postinstruction testing showed students’ understanding of natural selection increased substantially after completing this series of learning activities. Testing throughout this unit showed steadily increasing student understanding, and surveys indicated students enjoyed the activities. 相似文献

Viral flows of counterpublicity are an increasingly common occurrence in the global modular network of the modern public spheres. This article applies a public sphere theoretical framework built upon the radical or agonistic tradition and a critical discourse analytical methodological framework to interpret the example of the 2009 New Zealand Internet Blackout, which was mobilized in protest against impending copyright legislation that would have rendered the Aotearoa New Zealand environment one of the harshest in the world. It shows that viral counterpublicity can generate successful counterhegemonic projects and even bring about legislative change, and in doing so, makes the argument that our understanding of what the modern public sphere is should allow for more unruly and contentious forms of democratically legitimate communication. 相似文献

Many students do not recognize that individual organisms within populations vary, and this may make it difficult for them to recognize the essential role variation plays in natural selection. Also, many students have weak scientific reasoning skills, and this makes it difficult for them to recognize misconceptions they might have. This paper describes a 2-h laboratory for college students that introduces them to genetic diversity and gives them practice using hypothetico-deductive reasoning. In brief, the lab presents students with DNA sequences from Africans, Europeans, and Asians, and asks students to determine whether people from each continent qualify as distinct "races." Comparison of the DNA sequences shows that people on each continent are not more similar to one another than to people on other continents, and therefore do not qualify as distinct races. Ninety-four percent of our students reported that the laboratory was interesting, and 79% reported that it was a valuable learning experience. We developed and used a survey to measure the extent to which students recognized variation and its significance within populations and showed that the lab increased student awareness of variation. We also showed that the lab improved the ability of students to construct hypothetico-deductive arguments. 相似文献

Previous research has shown that adolescents' attention for a peer is determined by the peer's status. This study examined how it is also determined by the status of the perceiving adolescent, and the gender of both parties involved (perceiver and perceived). Participants were 122 early adolescents (M age = 11.0 years) who completed sociometric measures and eye‐tracking recordings of visual fixations at pictures of high‐status (popular) and low‐status (unpopular) classmates. Automatic attention (first‐gaze preference) and controlled attention (total gaze time) were measured. Target popularity was associated with both measures of attention. These associations were further moderated by perceiver popularity and perceiver and target gender. Popular adolescents attracted attention especially from other popular adolescents. Popular boys attracted attention especially from girls. 相似文献

An attempt is made to reconsider the implications of Piaget's theories for the teaching of reading. It is argued that the way the theories have typically been interpreted in relation to reading is unhelpful and does not accord with the behaviour of young readers. Alternative ways of linking Piagetian theory to the teaching of reading are proposed. It is considered that they both provide a more adequate explanation and offer the teacher more helpful directions along which to develop reading. 相似文献
