MK-801 interferes with the acquisition of amphetamine- and lithium-induced place conditioning

The place conditioning paradigm was used to assess the ability of the noncompetitive NMDA receptor antagonist, MK-801, to interfere with drug-place associations. MK-801 (0.1 mg/kg, i.p.) attenuated a place preference produced by high, but not low to moderate, doses of amphetamine. Interference with amphetamine place preference learning was not the result of state-dependent retrieval produced by MK-801. Furthermore, MK-801 did not interfere with the expression of a previously established amphetamine place preference. Pretreatment with MK-801 also interfered with lithium-induced conditioned place aversion learning. These results suggest that the attenuation of place preference conditioning produced by MK-801 is the result of its interference with learning rather than with the rewarding properties of drugs.     

Learning from Writing in College Biology

This study used both quantitative and qualitative analyses to examine the influence of written arguments on learning in a college level introductory biology class and the types of metacognition employed by students while writing. Comparison of a treatment and control group indicates that the writing assignments used had minimal impact on overall content learning as measured by conventional exams. Subsequent interviews and think-aloud protocols with a subset of students indicated that writing arguments had the potential to foster learning through forward and backward search strategies. However, few of the students took advantage of this opportunity to use metacognitive skills. This study suggests that preparing written arguments is not sufficient, by itself, to have a reliable effect on student learning and is consistent with the view that students must be explicitly taught when and how to use different metacognitive strategies.     

A National Survey of School Counselor Preparation Programs: Screening Methods,Faculty Experiences,Curricular Content,and Fieldwork Requirements

This article describes the results of a national survey regarding the preparation of entry‐level school counseling students. The questionnaire asked counselor educators about credit hours, screening methods, previous faculty experiences in a school setting, course content, and fieldwork requirements. Survey results revealed similarities and differences among school counselor preparation programs.     

Enriching the historiography of Religious Education: insights from oral life history

This article seeks to exemplify the extent to which oral life history research can enrich existing historiographies of English Religious Education (RE). Findings are reported from interviews undertaken with a sample of key informants involved in designing and/or implementing significant curriculum changes in RE in the 1960s and 1970s. The interviews provided insights into personal narratives and biographies that have been marginal to, or excluded from, the historical record. Thematic analysis of the oral life histories opened a window into the world of RE, specifically in relation to professional identity and practice, curriculum development and professional organisations, thereby exposing the operational dynamics of RE at an (inter-)personal and organisational level. The findings are framed by a series of methodological reflections. Overall, oral life histories are shown to be capable of revealing that which was previously hidden and which can be confirmed and contrasted with knowledge gleaned from primary documentary sources.     

Assessing the impact of information services in a regionalized health-care organization

Objectives: Assessment of the usage of medical library services before and after the implementation of several new services, as well as assessment of the clinical impact of the information provided by the medical library. Methods: A sample of employees, residents and physicians were surveyed using a stratified, random selection process in two surveys 4 years apart. The response rate for the first survey was 52% and the response rate for the second survey was 35.2%. Results: Differences in usage included increased overall use of the librarians and library services, decreased use of the Internet as a source of information, and direct and indirect impacts upon patient care. Information needs of respondents also increased to where 65% of employees and 94% of physicians require information at least once a week. Patient management was the main reason for needing information. The top two specific uses were to find out about a condition and determine a treatment plan. Conclusions: These findings parallel some of the findings of other researchers, and contradict the findings of others. Possible explanations for these findings and implications for future research are discussed.     

Building Vocabulary Knowledge in Preschoolers Through Shared Book Reading and Gameplay

This study moves beyond previous investigations to examine whether an educational intervention combining shared book reading with a vocabulary game increases children's vocabulary knowledge. Four‐year‐olds (N = 44) were randomly assigned to dyads in either an intervention (shared book reading plus vocabulary review game) or comparison condition (shared book reading, after‐reading vocabulary review, and game that did not teach vocabulary). After two 30‐min sessions, results demonstrated that the intervention condition outperformed the comparison condition on measures of receptive and expressive knowledge of taught vocabulary words. Children in the intervention group who scored the lowest at pretest on the receptive measure saw the most gains in taught word knowledge. Findings suggest that combining vocabulary gameplay with shared book reading improved children's learning of the vocabulary words in comparison to a comparison group.     

Do You Want to Know What I Learned? Using Informational Trade Books as Models to Teach Text Structure

Informational text is an important resource for classroom teachers that places unique comprehension demands on young students. Research on teaching expository text structure to young children shows that explicit instruction improves student comprehension. This practical article addresses how to use “well-structured” expository trade book titles to teach text structure. A lesson plan template and an extended example of an explicit lesson on order/sequence are provided.     

Effect of Time on Perceived Gains from an Undergraduate Research Program

The current study examines the trajectories of student perceived gains as a result of time spent in an undergraduate research experience (URE). Data for the study come from a survey administered at three points over a 1-yr period: before participation in the program, at the end of a Summer segment of research, and at the end of the year. Repeated-measures analysis of variance was used to examine the effect of time on perceived gains in student research skills, research confidence, and understanding of research processes. The results suggest that the students experienced different gains/benefits at developmentally different stages of their UREs. Participants reported gains in fewer areas at the end of the Summer segment compared with the end of the yearlong experience, thus supporting the notion that longer UREs offer students more benefit.
