When and why do initially high-achieving poor children fall behind?

In this paper, we examine the trajectories of initially higher- and lower-achieving children from lower and higher socio-economic status families from primary school through to university in England for the first time. We also explore what explains these trajectories. This enables us to provide new insights into when and why the performance of children with similar initial achievement diverges on the basis of their socio-economic background. Our results indicate that pupils from poor backgrounds who are higher achievers in primary school fall behind their better-off but lower-achieving peers during secondary school. This suggests that secondary school may be a critical period to intervene to prevent poor children from falling behind their richer peers. Our analysis suggests that there is less divergence in performance between pupils from different socio-economic backgrounds who attend the same schools. This result is particularly strong for children with low initial achievement. While we remain cautious about the implications of these findings, they provide suggestive evidence that schools (or the sorting of pupils into schools) play an important role in explaining why the test scores of richer and poorer children diverge over time.     

Collaborative development of anatomy workshops for medical and dental students in Cambodia

After Phnom Penh was liberated from the Khmer Rouge in 1979, health science education in Cambodia had to be completely rebuilt. In this article, the authors report the results of a teaching collaboration between the University of Melbourne (Australia), the International University (Cambodia), and the University of Health Sciences (Cambodia). The main objectives in this collaboration were to provide the opportunity for dental and medical students in Cambodia to attend resourced anatomy workshops and to provide an opportunity for anatomy teachers in Cambodia to gain experience in implementing anatomy workshops of the style that are routinely used in the medical and dental curricula at the University of Melbourne. Experienced anatomy educators from the Department of Anatomy and Cell Biology, University of Melbourne, designed and resourced a series of workshops and then delivered these in collaboration with Cambodian teaching staff in Phnom Penh. The Cambodian students who participated in the workshops were incredibly engaged and enthusiastic. The students' evaluations (by questionnaire) indicated a very positive response to the workshops. All of the workshop resources were donated to the two universities so that the staff could continue to implement similar workshops, and plans were developed to continue our collaboration by developing more resourced workshops for this purpose in the future. Two staff members from Cambodia will travel to Melbourne to participate in anatomy workshops and dissection classes at the University of Melbourne. We hope that this extension of the collaboration provides further support and impetus for the development of anatomy education in Cambodia in the future.     

Measurements of drag and lift on tennis balls in flight

Measurements are presented of drag and lift on new tennis balls in flight. Two video cameras were used to measure the velocity and height of the balls at two positions separated horizontally by 6.4 m. The balls were fired from a ball launcher at speeds between 15 and 30 m/s and with topspin or backspin at rates up to 2,500 rpm. Significant shot-to-shot variations were found in both the drag and lift coefficients. The average drag coefficient was 0.507 ± 0.024, independent of ball speed or spin, and lower than the value usually observed in wind tunnel experiments. The lift coefficient increased with ball spin, on average, but significant lift was observed even at very low spin. The latter effect can be attributed to a side force arising from asymmetries in the ball surface, analogous to the side force responsible for the erratic path of a knuckleball in baseball.     

Developing a Test of Scientific Literacy Skills (TOSLS): Measuring Undergraduates�� Evaluation of Scientific Information and Arguments

Life sciences faculty agree that developing scientific literacy is an integral part of undergraduate education and report that they teach these skills. However, few measures of scientific literacy are available to assess students’ proficiency in using scientific literacy skills to solve scenarios in and beyond the undergraduate biology classroom. In this paper, we describe the development, validation, and testing of the Test of Scientific Literacy Skills (TOSLS) in five general education biology classes at three undergraduate institutions. The test measures skills related to major aspects of scientific literacy: recognizing and analyzing the use of methods of inquiry that lead to scientific knowledge and the ability to organize, analyze, and interpret quantitative data and scientific information. Measures of validity included correspondence between items and scientific literacy goals of the National Research Council and Project 2061, findings from a survey of biology faculty, expert biology educator reviews, student interviews, and statistical analyses. Classroom testing contexts varied both in terms of student demographics and pedagogical approaches. We propose that biology instructors can use the TOSLS to evaluate their students’ proficiencies in using scientific literacy skills and to document the impacts of curricular reform on students’ scientific literacy.     

LONGITUDINAL PREDICTION OF 1ST AND 2ND GRADE ENGLISH ORAL READING FLUENCY IN ENGLISH LANGUAGE LEARNERS: WHICH EARLY READING AND LANGUAGE SKILLS ARE BETTER PREDICTORS?

This study investigates the relation between Spanish and English early literacy skills in kindergarten and first grade, and English oral reading fluency at the end of first and second grade in a sample of 150 Spanish‐speaking English language learners. Students were assessed in kindergarten, first, and second grades on a broad bilingual academic battery that included phonological awareness, letter knowledge, vocabulary, word reading, and oral reading fluency. These measures were analyzed using hierarchal multiple regression to determine which early reading skills predicted English oral reading fluency scores at the end of first and second grade. Predictive relationships were different between English and Spanish measures of early literacy and end of year first grade and second grade English oral reading fluency. This study has important implications for early identification of risk for Spanish‐speaking English language learners as it addresses the input of both Spanish and English early reading skills and the relation between those skills and English oral reading fluency.     

The Effect of Computer-Based Tests on Racial-Ethnic and Gender Groups

In this study data were examined from several national testing programs to determine whether the change from paper-based administration to computer-based tests (CBTs) influences group differences in performance. Performances by gender, racial, and ethnic groups on the Graduate Record Examination General Test, Graduate Management Admissions Test, SAT I: Reasoning Test, and Praxis: Professional Assessment for Beginning Teachers, were analyzed to determine whether the shift in testing format from paper-and-pencil tests to CBTs posed a disadvantage to any of these subgroups, beyond that already identified for paper-based tests. Although all differences were quite small, some consistent patterns were found for some racial-ethnic and gender groups. African-American examinees and, to a lesser degree, Hispanic examinees appear to benefit from the CBT format. On some tests, female examinees' performance was relatively lower on the CBT version.     

Sexual approach conditioning: Omission contingency tests

Male Japanese quail learned to approach a light that predicted visual exposure to a female quail. In Experiment 1, duration of visual exposure to the female did not systematically affect the speed or strength of conditioning. Introduction of an omission contingency for approach to the light after acquisition did not suppress conditioned approach relative to the performance of yoked controls. In Experiment 2, males learned to approach a light that predicted visual exposure to a female despite an omission contingency for approach in effect during acquisition. Experimental males were not slower to acquire the approach response under an omission contingency than were yoked controls. The findings indicate strong Pavlovian control of sexual conditioned approach in Japanese quail.     

An urban school renewal program: A case analysis

Conclusion One of the most gratifying returns was a chance comment offered by a teacher as we walked across the lawn toward a local fast food restaurant. We were chatting about what he had experienced during the preceding two years. You know, he said, when we began this, I didn't see many hopeful signs, but I think that most of us (teachers) feel now that we work in the best high school in the city. The source may have been biased, and rigorous controls were obviously lacking, but that is the way one teacher perceived the changes. Many gained planning, leadership, problem solving, and other important behavioral and coping skills that contributed in interactively subtle, but nevertheless real ways.Can good things be made to happen in urban schools? The quantified data are equivocal, but we believe that the associations among interventions and perceived changes support cautious optimism.     

Making and Mistaking Reality: What is Emotional Education?

A central thesis of this paper is that the mind and its thought evolve out of the experience of the whole person in their unique surroundings. It attempts to articulate the meaning and value of Emotional Education, especially in its relation to thought processes. It shows the value of learning from the particular, and from awareness of feeling states. It shows how making emotional enquiry can change the nature of the thinking, reducing the need of the thinker, and involves experiencing while not-knowing as well as more usual rational approaches.Recent affirmations from neuroscience of the psychoanalytic picture of conscious awareness arising from unconscious emotional processes are noted. Systemic and emotional thought processes are described and illustrated.While the nature of unconscious choice is recognised as part of all thought process, the “use of self” is explored as a conscious means of influencing the nature of thinking, and the attributes of both person and context necessary to flourishing thought are contrasted with the human needs which produce mistaken thought. Some questions which have been asked by students in Emotional Education classes, about free will, abuse, and ethics are raised. I hope the gratitude to people who have shared their feelings in order to think and be thought about in “emotional thinking” is evident; it is very real to me.
