The Intersection of Inquiry-Based Science and Language: Preparing Teachers for ELL Classrooms

As teacher educators, we are tasked with preparing prospective teachers to enter a field that has undergone significant changes in student population and policy since we were K-12 teachers. With the emphasis placed on connections, mathematics integration, and communication by the New Generation Science Standards (NGSS) (Achieve in Next generation science standards, 2012), more research is needed on how teachers can accomplish this integration (Bunch in Rev Res Educ 37:298–341, 2013; Lee et al. in Educ Res 42(4):223–233, 2013). Science teacher educators, in response to the NGSS, recognize that it is necessary for pre-service and in-service teachers to know more about how instructional strategies in language and science can complement one another. Our purpose in this study was to explore a model of integration that can be used in classrooms. To do this, we examined the change in science content knowledge and academic vocabulary for English language learners (ELLs) as they engaged in inquiry-based science experience utilizing the 5R Instructional Model. Two units, erosion and wind turbines, were developed using the 5R Instructional Model and taught during two different years in a summer school program for ELLs. We analyzed data from interviews to assess change in conceptual understanding and science academic vocabulary over the 60 h of instruction. The statistics show a clear trend of growth supporting our claim that ELLs did construct more sophisticated understanding of the topics and use more language to communicate their knowledge. As science teacher educators seek ways to prepare elementary teachers to help preK-12 students to learn science and develop the language of science, the 5R Instructional Model is one pathway.     

Understanding parental views of adolescent sexuality and sex education in Ecuador: a qualitative study

Parents' contribution to sex education is increasingly receiving research attention. This growing interest stems from recognition of the influence that parental attitudes may have both on young people's sexual attitudes and behaviour, and on school-based sex education. Studies regarding parental attitudes towards sexuality are, however, still rare. The two main objectives of this study were to explore parental views about sexuality and to understand parental attitudes towards sex education. Four focus group discussions were conducted with parents from high schools in Cuenca, Ecuador. Data were analysed using thematic analysis. The study revealed that parents held a restricted view about sex education, grounded in traditional religious ideas about sexuality, which led parents to understand it as a morally and physically dangerous activity. Although parents expressed a willingness to make good quality sex education available to their children, they reported having insufficient personal resources to fulfil that objective. The results of this study provide important information about the need to develop and adapt sex education to each specific cultural context, thereby confirming the importance of knowing about the cultural traditions and religious beliefs that may form obstacles to effective sex education for young people in Ecuador.     

Tert-butyl amine borane complex: An unusual application of a reducing agent on model molecules of cellulose based materials

The need to preserve cultural heritage on paper requires the setting up of methods and treatments that can be applied to original documents. The cellulose main degradation processes are hydrolysis and oxidation. Only the first one has been widely investigated. The Istituto Centrale per la Patologia del Libro (ICPL) focused its attention on oxidation phenomena and studied a particular class of reducing agents, namely the borane-amine complexes. During the investigation it was found that the borane tert-butylamine complex, besides being the most promising reducing agent, was also able to react with carboxylic functions. In the present study ¹H and ¹³C NMR, Pulsed field gradient NMR spectroscopy as well as Raman spectroscopy were used as analytical tools to disclose the mechanism of the interaction between the borane tert-butylamine complex and the carboxylic functions. Given the complexity of the paper/environment interactions and the subsequent degradation phenomena, we worked on simplified models based on small carbohydrate molecules in order to reproduce the behavior of degraded paper after reductive restoration. Modified D-glucose and D-cellobiose were used in this first step in order to set up the analytical methods before approaching more complex systems such as microcrystalline cellulose and paper. Our results give the experimental evidence that borane tert-butylamine complex is also able to neutralize acidic functions. This finding has important perspectives in paper restoration.     

Police bodies and police minds: professional learning through bodily practices of sport participation*

The purpose of this paper is to contribute to the literature concerned with bodily perspectives on professional learning by reporting on a study of Swedish police officers’ sport participation as a form of occupational learning. The study seeks to answer how ideals of work practice and sport participation intersect, how professional learning is channelled through sport participation, and how such bodily practices might have excluding effects on professional participation. Using a practice theory framework, the Schatzkian concept of teleoaffective structure guides the analysis. Sixteen interviews were conducted with police officers who practice police sports. The analysis targeted symbolic manifestations of teleoaffectivity, and the findings indicate five overlapping ideals between sport and police practice. In addition, one police specific ideal was constructed. Based on these findings, we discuss how professionals learn by participation in practices not directly related to the work in question, and how such learning includes and excludes from participation.     

The effects of a history‐based instructional material on the students' understanding of field lines

Many students in physics courses fail to achieve a desired conceptual change because they assign an incorrect ontology to the to‐be‐learned concept. This situation has been detected in previous research for the case of field lines: many college students assign material properties to the lines and describe them, for example, as tubes that contain or transport charges. The historical evolution of this concept shows that early scientists like Faraday assigned material properties to these lines in some occasions. In the present work a history‐based instructional material was designed to foster the analysis of the ontology of field lines to help students at an Argentinean university achieve conceptual change. The predicates used by the students to describe physical situations were used as evidence of the assigned ontological status. Conceptual change was measured by the change in the proportion of geometrical predicates that students used when referring to the lines in a written questionnaire. This change was significantly higher for the students learning with the history‐based material compared to those that learned in the regular class. Some characteristics of the material and geometrical ideas that students hold about the field lines were determined through an oral interview. © 2006 Wiley Periodicals, Inc. J Res Sci Teach

Developing Online Tutorials to Improve Information Literacy Skills for Second-Year Nursing Students of University College Dublin

This article explores the process of developing online tutorials for a specified student group, in this case Second-Year Nursing students in University College Dublin. The product was commissioned by the Health Sciences Library and the UCD School of Nursing, Midwifery, and Health Systems. It was developed as a “Capstone Project” for part fulfillment of the MLIS in UCD.

We focused our research on three areas of scholarship to assist in the development of our product, namely Information Behavior, Learning Technologies, and Learning Science and Design. Flemings VARK model was used to inform the team of the four different learning styles (visual, auditory, reading, and kinesthetic) and to match the presentation style to these.

An initial difficulty in the assessment phase was one of access to a large group of students, as the students were on clinical placements. We created personas and a profile of nursing students to try and compensate for this. The tutorial was developed to cater for this specific group of students and later to act as a valuable support to the Library, which is under severe pressure in terms of staff availability to support student learning.

The product is relatively straightforward to produce (and maintain) and is something the Library will be able to develop and add to in future years.
