ABSTRACT— Effective teaching should focus on representational change, which is fundamental to learning and education, rather than conceptual change, which involves transformation of theories in science rather than the gradual building of knowledge that occurs in students. This article addresses the question about how to develop more efficient strategies for promoting representational change across cognitive development. I provide an example of an integrated structural model that highlights the underlying cognitive structures that connect numbers, mathematical operations, and functions. The model emphasizes dynamic multiple representations that students can internalize within the number line and which lead to developing a dynamic mental structure. In teaching practice, the model focuses on a counting task format, which integrates a variety of activities, specifically addressing motor, visual, and verbal skills, as well as various types of learning transfer. 相似文献

The emphasis given to experimental problem-solving skills in science curriculum innovation has not been matched by the development of comparable assessment tools. Multiple-choice tests were constructed for seven skills using learning hierarchies based on expert-novice differences. The instruments were refined in three phases of field testing. The reliabilities of the tests are sufficient for making judgments of group performance, but are insufficient in a single administration for individual assessment. Evidence of the validity of the tests is presented and their worth is discussed within the framework of a theory of instruction. 相似文献

ABSTRACTContext-based learning (CBL) is advocated as beneficial to learners, but more needs to be understood about how different contexts used in courses influence student outcomes. Gilbert defined several models of context that appear to be used in chemistry. In one model that achieves many criteria of student meaning-making, the context is provided by ‘personal mental activity’, meaning that students engage in a role to solve a problem. The model’s predicted outcomes are that students develop and use the specialised language of chemistry, translate what they learn in the immediate context to other contexts, and empathise with the community of practice that is created. The first two of these outcomes were investigated in two large-enrolment university chemistry courses, both organised as this CBL model, in which students were introduced to kinetic molecular theory (KMT). Sample 1 students (N1?=?105) learned KMT through whole-class kinaesthetic activity as a human model of a gas while focusing on a problem identifying substances in balloons filled with different gases. Sample 2 students (N2?=?110) manipulated molecular dynamics simulations while focusing on the problem of reducing atmospheric CO2. Exam answers and pre-/post-test responses, involving a new KMT context, were analysed. Students in Sample 1 demonstrated a stronger understanding of particle trajectories, while Sample 2 students developed more sophisticated mechanistic reasoning and greater fluidity of translation between contexts through increased use of chemists’ specialised language. The relationships of these outcomes to the contexts were examined in consideration of the different curriculum emphases inherent in the contexts. 相似文献

This comparative study examined the relationship between self-efficacy theory and contraceptive practices in male and female adolescents enrolled in Midwestern University. A survey method was employed to obtain data from 101 female and 106 male subjects aged 18-20, sexually active, single, and who had one sexual partner for at least 3 months. Findings suggest that both genders need to develop the necessary communication skills in sexual matters and contraceptive issues. Females scored low on several self-efficacy statements that involve the ability to communicate about sexual matters and securing the use of contraception. They also obtained a low score in statements that require assertiveness in preventing sexual intercourse in highly involved situations. Meanwhile, male subjects scored low in items involving communication skills. Finally, contraceptive self-efficacy was found to be significantly different for males and females in the following areas: females need to learn how to assume responsibility and to become more effective in securing contraceptives; and males need to learn to be assertive about avoiding sexual intercourse when not using contraception and to develop the ability to talk about using contraceptives. 相似文献

The purpose of the paper is threefold. First, it presents empirical data about paternal and maternal games displayed with toddlers in a play situation with polyvalent objects. Both parents proposed predictable routines through conventional games. But differences in parental games also occurred, as fathers proposed new ways of using the objects through non conventional games more than mothers did. Second, those results are interpreted in terms of paternal specific contributions to development. In fact, in such play situations with toddlers, paternal behaviors are more destabilizing than maternal ones. Last, we discuss whether paternal irregularities in such play situation with objects may favor cognitive development, as well as structurant maternal regularities in the same situation. More generally, the complementary contributions of maternal and paternal perturbations in different kind of situations (play, language development) are questioned. 相似文献

This multiple case study examined the coauthorship process in research laboratories of different university departments. The study focused on two cases comprising five writing teams, one in biochemistry and microbiology and four in earth and ocean sciences. The role of the research supervisor, the role of the student (graduate and postgraduate), the interaction of the supervisor and the student, the activities and processes inherent in the coauthorship process, and the student's beliefs, expertise, scientific writing, and entry into an academic discourse community were documented utilizing multiple sources of data and methods. Several activities and processes were found to be common across all coauthorship teams, including aspects of planning, drafting, and revising. Elements of scientific and writing expertise, facets of enculturation into scientific research and discourse communities, academic civility, and the dynamics of collaborative groups also were apparent. There was healthy tension and mutual respect in the research groups as they attempted to make sense of science, report their results clearly and persuasively, and share the responsibilities of expertise. The novice scientists came to appreciate that the writing, editing, and revising process influenced the quality of the science as well as the writing. © 2004 Wiley Periodicals, Inc.

Transition to Kindergarten: Family Experiences and Involvement 总被引:2,自引:0,他引:2

The transition to kindergarten is an important developmental milestone for young children, their families, and teachers. Preparing
students for successful kindergarten transition has been identified as a national priority, yet the degree to which parents
are involved in kindergarten preparation is rarely considered. This study investigated the family experiences and involvement
in kindergarten transition in 132 families whose children had completed early education programs and were beginning kindergarten.
Results suggest that the majority of families wanted more involvement in the transition to kindergarten planning and wanted
information about kindergarten readiness, including academic and behavioral expectations. The top concerns expressed by families
were attending a new school and difficulties with following directions or other behavior problems. Families with fewer financial
resources reported less involvement in transition activities than families with more resources. Implications for early childhood
education are discussed, in light of the growing emphasis on parent involvement and kindergarten readiness.
