A Path Analysis of Nutrition,Stimulation, and Child Development Among Young Children in Bihar,India

Nutrition plays an important role in the development of a child, particularly in low‐ and middle‐income countries where malnutrition is often widespread. The relation between diet, hemoglobin, nutritional status, motor development, stimulation and mental development was examined in a cross‐sectional sample of 1,079 children 12–18 months of age living in rural Bihar, India. Path analysis revealed associations between (a) length‐for‐age z‐scores and motor development, standardized β (β) = .285, p < .001, and (b) motor and all mental development outcomes (language: β = .422; personal‐social: β = .490; memory: β = .139; and executive function: β = .072, all p < .001). Additionally, stimulation was significantly associated with language scores and hemoglobin concentration with memory. These findings inform interventions aimed at improving child development in Northern India.     

Evaluation of evidence-based medicine search skills in the clinical years

The librarians of the Health Sciences Library worked with the director of the Primary Care Clerkship to reinforce the principles of Evidence-Based Medicine (EBM) searching, taught during the first two years of medical school, through an intensive workshop. The purpose of the program was to ensure that students apply EBM principles in a timely and effective manner in clinical situations. Working in teams led by a resident and librarian, students researched real cases and then evaluated the effectiveness of their approach to the problems. This paper outlines the rationale for the team approach, reviews the administration of a computer-based workshop, and discusses the evaluation process. Evaluation focused on both the current workshop and its implications for the informatics program presented to students during years one and two.     

Evidence-based practice instruction by faculty members and librarians in North American optometry and ophthalmology programs

North American optometry and ophthalmology faculty members and vision science librarians were surveyed online (14% response rate) about teaching evidence-based practice (EBP). Similar to studies of other health care programs, all five EBP steps (Ask, Acquire, Appraise, Apply, Assess) were taught to varying degrees. Optometry and ophthalmology EBP educators may want to place further emphasis on (1) the Apply and Assess steps, (2) faculty- and student-generated questions and self-assessment in clinical settings, (3) online teaching strategies, (4) programmatic integration of EBP learning objectives, and (5) collaboration between faculty members and librarians.     

First-generation college students: Characteristics,experiences, and cognitive development

This study sought answers to three questions: (1) Do the precollege characteristics of first-generation students differ from those of traditional students? (2) Do first-generation students' college experiences differ from those of other students? (3) What are the educational consequences of any differences on first-year gains in students' reading, math, and critical thinking abilities? Answers come from 2,685 students (825 first-generation and 1,860 traditional students) who entered 23 diverse institutions nationwide in Fall 1992 and who completed one year of study. First-generation students differ from their traditional peers in both entering characteristics and college experiences. Although traditional students make greater net gains in reading during their first year, the two groups gain to about the same degree in math and critical thinking skills. Those gains, however, appear to result from somewhat different experiences.     

Approaches to teaching in mainstream and separate postsecondary classrooms

The study examined attitudes toward teaching reported by university instructors who normally teach hearing students (with the occasional deaf or hard of hearing student) and by instructors who normally teach deaf and hard of hearing students at the same institution. Overall, a view of instruction as information transmission was associated with a teacher-focused approach to instruction, whereas viewing instruction as a means of promoting conceptual change was associated with a student-focused approach. Instructors in mainstream classrooms were more oriented toward information transmission than conceptual change, whereas instructors experienced in separate classrooms for deaf and hard of hearing students reported seeking to promote conceptual change in students and adopting more student-focused approaches to teaching. These results are consistent with previous findings concerning instructors' approaches to teaching and deaf and hard of hearing students' approaches to learning, and may help explain recent findings regarding student outcomes in separate versus mainstream secondary classrooms.     

The Use of the Course Experience Questionnaire as a Monitoring Evaluation Tool in a Problem-based Medical Programme

This paper reports on the use of the Course Experience Questionnaire (CEQ) as an instrument to monitor the medical programme at the University of Sydney and in particular to measure improvements in teaching quality with the introduction of the new graduate-entry problem-based programme. In addition, it raises the more general issue of interpretation of CEQ results in courses designed around problembased learning (PBL). Students' perceptions of teaching quality were sought using a whole class questionnaire survey and small group interviews. Students in the new programme rated their course more highly than did students in the old programme with respect to good teaching, appropriate assessment, generic skills and overall satisfaction. These improvements did not hold with respect to the clarity of goals and standards, nor for perceptions of an appropriate workload. The results are interpreted in context and it is argued that particular items in the CEQ do not reflect the educational philosophy or the instructional processes of PBL programmes.     

Effectiveness of Spanish intervention for first-grade English language learners at risk for reading difficulties

The effectiveness of an explicit, systematic reading intervention for first-grade students whose home language was Spanish and who were at risk for reading difficulties was examined. Participants were 69 students in 20 classrooms in 7 schools from 3 districts who initially did not pass the screening in Spanish and were randomly assigned within schools to a treatment or comparison group; after 7 months, 64 students remained in the study. The intervention matched the language of instruction of their core reading program (Spanish). Treatment groups of 3 to 5 students met daily for 50 min and were provided systematic and explicit instruction in oral language and reading by trained bilingual intervention teachers. Comparison students received the school's standard intervention for struggling readers. Observations during core reading instruction provided information about the reading instruction and language use of the teachers. There were no differences between the treatment and comparison groups in either Spanish or English on any measures at pretest, but there were significant posttest differences in favor of the treatment group for the following outcomes in Spanish: Letter-Sound Identification (d = 0.72), Phonological Awareness composite (d = 0.73), Woodcock Language Proficiency Battery-Revised Oral Language composite (d = 0.35), Word Attack (d = 0.85), Passage Comprehension (d = 0.55), and two measures of reading fluency (d = 0.58-0.75).     

Nonreinforced flavor exposure attenuates the effects of conditioned taste aversion on both flavor consumption and cue palatability

Nonreinforced exposure to a cue tends to attenuate subsequent conditioning with that cue—an effect referred to as latent inhibition (LI). In the two experiments reported here, we examined LI effects in the context of conditioned taste aversion by examining both the amount of consumption and the microstructure of the consummatory behavior (in terms of the mean size of lick clusters). The latter measure can be taken to reflect affective responses to, or the palatability of, the solution being consumed. In both experiments, exposure to a to-be-conditioned flavor prior to pairing the flavor with nausea produced by lithium chloride attenuated both the reduction in consumption and the reduction in lick cluster sizes typically produced by taste aversion learning. In addition, we observed a tendency (especially in the lick cluster measure) for nonreinforced exposure to reduce neophobic responses to the test flavors. Taken together, these results reinforce the suggestion from previous experiments using taste reactivity methods that LI attenuates the effects of taste aversion on both consumption and cue palatability. The present results also support the suggestion that the failure in previous studies to see concurrent LI effects on consumption and palatability was due to a context specificity produced by the oral taste infusion methods required for taste reactivity analyses. Finally, the fact that the pattern of extinction of conditioned changes in consumption and in lick cluster sizes was not affected by preexposure to the cue flavors suggests that LI influenced the quantity but not the quality of conditioned taste aversion.     

Developing a comprehensive model of risk and protective factors that can predict spelling at age seven: findings from a community sample of Victorian children

The paper reports on a study designed to develop a risk model that can best predict single-word spelling in seven-year-old children when they were aged 4 and 5. Test measures, personal characteristics and environmental influences were all considered as variables from a community sample of 971 children. Strong concurrent correlations were found between single-word spelling and single-word reading while expressive language and, to a lesser extent, receptive language were less strongly correlated. Predictors of single-word spelling at ages 4 and 5 were dominated by child-related factors such as letter knowledge, a history of speech impairment and expressive language along with maternal word reading ability. Based on the strength of the predictive factors identified at both age 4 and 5, our results provide initial support for using a targeted model for screening pre-schoolers at risk of not mastering spelling in a timely manner.
