Using Analogy to Help Young Children Understand

Analogies offer conceptual models for supporting the development of understanding. Contrary to some expectations, there is growing evidence that young children can reason analogically. Much of this evidence comes from experiments intended to test psychological theories. This study aimed to gauge the practical potential of analogy in topics often considered by teachers difficult for young children to understand. Aspects of young children's understanding of current electricity were compared in two conditions, namely with and without an analogy (87 and 89 children, respectively; 6‐7 years of age). The results indicated that the analogy was of practical value in teaching for understanding. It is suggested that their bases be carefully prepared prior to teaching the target topic and that what is to be understood is modelled directly and is explicitly related to its equivalent in the topic. Further investigations to determine conditions for the effective use of analogies when teaching young children, who benefits particularly and in what ways seem warranted.     

Designing a program to prepare graduate students for careers as college teachers

Graduate students have few opportunities to gain experience in the full range of teaching and to become aware of the issues related to a career of teaching in higher education. A program designed to provide these opportunities must accommodate both the variation within the institution's graduate programs and the complexities of graduate student life to be successful. The University of California, Davis, developed the Program in College Teaching in which participants develop and then fulfill contractual agreements for a faculty guided investigation into teaching in the discipline and supporting individualized activities focused on the practice and issues of teaching in higher education. This article notes five factors and assumptions of program development, discusses how they impact a program for training graduate students to be college teachers, describes the current Program and evaluates its pilot year.William E.

Does Early Mathematics Intervention Change the Processes Underlying Children's Learning?

Early educational intervention effects typically fade in the years following treatment, and few studies have investigated why achievement impacts diminish over time. The current study tested the effects of a preschool mathematics intervention on two aspects of children's mathematical development. We tested for separate effects of the intervention on “state” (occasion-specific) and “trait” (relatively stable) variability in mathematics achievement. Results indicated that, although the treatment had a large impact on state mathematics, the treatment had no effect on trait mathematics, or the aspect of mathematics achievement that influences stable individual differences in mathematics achievement over time. Results did suggest, however, that the intervention could affect the underlying processes in children's mathematical development by inducing more transfer of knowledge immediately following the intervention for students in the treated group.     

Learning from Tables

Information is often tabulated, both for the general public and for students in the classroom. The relative effectiveness of tabulated data and prose for making some aspects of data and co‐variation memorable was investigated. Three types of variable (categoric, discrete and continuous) and various patterns in the data were tested on 94 Year 9 students (13—14 years old). The effect of post‐questions on recall was also studied. Tabulating data was found to be generally superior to embedding it in prose as far as recall of data and co‐variation are concerned. Other factors which particularly affected recall included the pattern in the data and the ability of the student as defined by the school. The type of variable seemed to be less important for these students and the data tested. The post‐questions used here did not enhance recall of data or co‐variation. Some aspects of mental model theory were found useful in explaining the effects.     

The place of qualitative research in science education

This article develops a way to conceptualize the complementarity of quantitative and qualitative research in science education. The differing sets of metaphysical presuppositions that give rise to the two approaches are systematically examined by using Stephen Pepper's “world hypotheses”: it is argued and demonstrated that quantitative research is formist/ mechanist in its metaphysical preoccupation, while qualitative research is contextualist/organicist. The vehicle for demonstrating how these metaphysical systems actually influence science education research is Stephen Toulmin's “argument pattern.” It is demonstrated through analysis of examples that quantitative and qualitatitive research reports follow the same pattern of argument, even though the metaphysical roots behind the approaches, which control their differing methodologies and other features, are obviously different. Given the emergence of qualitative research styles, implications are explored for the development of science education research as a total enterprise. Special attention is paid to the problems of appraising the quality of qualitative research reports and to the need for a comprehensive view of what constitutes legitimate research in science education.     

Using curriculum-based measurement to inform reading instruction

The focus of this article is recent CBM work that incorporates diagnostic reading assessment. The goal is to help general and special educators tailor more effective reading instruction for developing readers. The development process for this CBM diagnostic reading assessment is described; the resulting assessment is presented; and preliminary data on its technical features and utility are provided. This research was supported in part by Grant #H324C000022 from the US Department of Education, Office of Special Education Programs, and Core Grant #HD15052 from the National Institute of Child Health and Human Development to Vanderbilt University.

Evaluating Discipline-Based Education Research for Promotion and Tenure

Discipline-based education research (DBER) is an emergent, interdisciplinary field of scholarship aimed at understanding and improving discipline-specific teaching and learning. The number of DBER faculty members in science, technology, engineering, and mathematics (STEM) departments has grown rapidly in recent years. Because the interdisciplinary nature of DBER involves social science, senior STEM faculty members may find it challenging to evaluate the quality or impact of DBER scholarship. This essay aims to address this issue by providing guidance on evaluating the scholarly accomplishments of DBER faculty members in a way that is useful to departmental colleagues and administrators during the tenure and promotion evaluation process.     

Using Mothers versus Trained Observers in Assessing Children's Secure Base Behavior: Theoretical and Methodological Considerations

The Attachment Q-Set (AQS) has emerged as a psychometrically sound method for assessing young children's secure base behavior in the home. However, considerable disagreement exists about whether mothers versus trained observers should be used as AQS sorters. The present study examined associations between mothers' and trained observers' AQS sorts for preschoolers, and assessed mother-observer concordance in relation to observers' confidence about how representative the behavioral samples they witnessed were of the domain of AQS items. Mothers with careful training and supervision on the AQS system completed AQS sorts with regard to their children's current behavior, and the same children were assessed with the AQS during a 2–3 hour visit 1–2 weeks later by trained, "blind" observers. Trained observers provided a confidence rating regarding the degree to which the samples of behavior observed were representative of the universe of AQS items. Mothers' and observers' sorts were significantly intercorrelated; however, observer sorts converged with mother sorts as observers' confidence ratings increased. Results are discussed in relation to circumstances that affect mother-observer reliability with the AQS and to factors that should be weighed when considering whether to use mothers versus trained observers as sorters.     

Developmental Change in Infants' Responses to Stress

Infant stress responses to a well-baby physical examination and inoculation were observed longitudinally at 2, 4, and 6 months of age. In general, there were cortisol increases over base to the procedures. Cortisol level and cortisol response decreased with age. These data indicate a developmental shift in adrenocortical functioning between 2 and 6 months of age. Further evidence for this shift was seen in the stability of individual responses between 4 and 6 months of age. Individual differences in both cortisol and behavioral responses showed the most stability between these 2 ages. Moreover, diurnal variation in baseline cortisol level was present only at 6 months of age. While a sizable minority of infants showed stress-related cortisol decreases to the procedures at a given age, there was no evidence for cross-age consistency in individual infants showing these cortisol decreases.
