We present an account of the work of Niels Bohr and Paul Dirac, their interactions and personalities.     

The use of public learning diaries in blended learning

Learning diaries—as we employ them—are students’ written reflections of their learning experiences and outcomes over the course of university seminars. The writing of such diaries is ‘tutored’ by a computer program: eHELp supports the writing of sophisticated learning diaries through a modelling and scaffolding of the phases of planning, production and revision. In addition, the learning diaries get published—by uploading them in a cooperation platform—so that the learners can read and discuss their peers’ diaries. The main function of such public learning diaries is to enrich traditional university courses (Blended Learning) with additional elaborative, organisational, critical reasoning, and metacognitive activities in order to foster a deeper processing and better retention of the contents to be learnt. We would like to present the educational rationale of our approach and report the findings of corresponding empirical studies.     

TEST ITEM ARRANGEMENT, TESTING TIME, AND PERFORMANCE

Two experiments were conducted to determine if a relationship exists between test item arrangements and student performance on power tests. The primary hypotheses were: item arrangements based upon item difficulty, similarity of content, or order of class presentation do not influence test score or required testing time. In the first experiment 122 subjects were randomly assigned to three item difficulty arrangements of 139 test items with a 0–100% difficulty range, and in the second experiment 156 subjects were randomly assigned to three item content arrangements of 103 items. Results of analyses of variance with test anxiety used as a classification factor supported the hypotheses.     

Ecumenical Worldview Development by Gender, Race, and Worldview: A Multiple-Group Analysis of Model Invariance

Based upon a national longitudinal dataset of 14,527 college students generated by the UCLA Spirituality in Higher Education Project, this study used structural equation modeling to test the applicability of a model of ecumenical worldview development for students of diverse genders, races, and worldviews. The model suggests that challenging co-curricular experiences and the salience of religion and spirituality in academic encounters tend to provoke religious/spiritual struggles, which in turn enhance ecumenical worldview. However, tests for model invariance revealed group differences in the applicability of the model. Differences by gender and race/ethnicity are minimal in comparison to differences by worldview.     

Identifying correlates of reabuse in maltreating parents

Forty-five abusive parents (40 mothers, 5 fathers) in treatment at a large, urban medical center's child abuse program were compared on 22 parent, child, and treatment variables posited to bear on reabuse. While no one variable by itself was strongly associated with reabuse, the data indicated that interactions involving several variables (e.g., income source, marital status, and the abuser's personal abuse history) significantly differentiated between reabusers and nonreabusers. Implications of the findings for research and clinical intervention are discussed.     

Differences on Bayley's infant behavior record for a sample of high-risk infants and their controls

3 groups of high-risk newborns and their controls were assessed at 92 weeks post-conceptional age using Bayley's Infant Behavioral Record (IBR). The 3 groups of high-risk infants were those who weighed 1,500 grams or less at birth and required no ventilator therapy, those weighing 1,500 grams or less at birth who required ventilator therapy, and newborns weighing more than 1,500 grams at birth who required ventilator therapy. Controls were healthy term infants matched for 7 socioeconomic and demographic variables. The first principal component of the IBR ratings for the 3 groups of high-risk infants and the controls were similar. All 3 groups of high-risk infants received less desirable IBR ratings on most items than their controls. In addition, there were some differences among high-risk groups; ventilated infants regardless of birth weight received the lowest ratings reflecting overall performance on the IBR, very low birthweight, ventilated newborns were more likely to receive ratings characterizing an overly active infant with a short attention span, and very low birth-weight, never-ventilated infants were most likely to be rated as happy but passive and delayed. The differences between the high-risk infants and controls in large part resulted from infants who were also delayed in terms of their mental and motor development.     

Training to use Television as a Teacher

Television, no longer in its infancy, no longer a novelty, still possesses the unique ability to focus, one may even say command, the attention of both the individual and the group. It is no doubt due to this quality that the use of television has developed greatly during recent years. The fact that it can keep pace with the contemporary scene (e.g. important events can be shown ‘live’ or soon after they have taken place) plus the personal method of presentation may have made it something more than a ‘teaching aid’.     

Needed: new models for linking the two cultures

Summaries

English

In recent years problems facing humankind have become more complex and challenging and have increasingly involved science and technology. While the public, generally, has been inadequately informed about such scientific and technical issues, public understanding of issues at the interface of science, society, and technology are an essential part of the resolution of societal problems. This paper outlines specific ways to promote understanding enabling individuals to participate more responsibly in enlightened democratic decision‐making responsive to societal needs. A systematic scheme is outlined with examples from two science education centres at tertiary institutions through activities including teaching, outreach, curriculum development, and research.     

Identifying the training experiences and needs of bilingual school psychologists

The purpose of this pilot study was to better understand the training experiences of bilingual school psychologists (BSPs) and identify their training needs in the provision of psychological services to English language learner students. The secondary aims of the study were to determine how school psychology programs can better prepare BSPs and incorporate best practices in bilingual competencies into their training models. Six BSPs (Spanish/English‐speakers) participated in the study; findings revealed four themes related to their training experiences: (a) programmatic limitations, (b) assumption that language equals competence, (c) going beyond the classroom, and (d) experiential training. In addition, as a result of their training experiences, the BSPs provided training recommendations in two major areas: (a) trainers and (b) culturally relevant curriculum. Implications for school psychology trainers will be provided.
