Hospitals and consumer health information in New Zealand: the role of the library

A research project was conducted with the primary objective of finding out what New Zealand hospitals are doing about providing consumer health information to patients, and specifically, the role played by hospital libraries. A database was compiled of all New Zealand hospitals, both public and privately funded. An individual responsible for consumer health information was identified at each hospital and a questionnaire sent directly to them. A 64% response rate was achieved, representing 196 hospitals. Fifty‐four hospitals reported having an in‐house Library or Information Centre for patients, but the materials and services provided varied widely. Results from this survey show that the provision of consumer health information in the hospital sector in New Zealand is ad hoc, and libraries are not necessarily involved.     

Secondary School Students’ Understanding of Science and Their Socioscientific Reasoning

Research in socioscientific issue (SSI)-based interventions is relatively new (Sadler in Journal of Research in Science Teaching 41:513–536, 2004; Zeidler et al. in Journal of Research in Science Teaching 46:74–101, 2009), and there is a need for understanding more about the effects of SSI-based learning environments (Sadler in Journal of Research in Science Teaching 41:513–536, 2004). Lee and Witz (International Journal of Science Education 31:931–960, 2009) highlighted the need for detailed case studies that would focus on how students respond to teachers’ practices of teaching SSI. This study presents case studies that investigated the development of secondary school students’ science understanding and their socioscientific reasoning within SSI-based learning environments. A multiple case study with embedded units of analysis was implemented for this research because of the contextual differences for each case. The findings of the study revealed that students’ understanding of science, including scientific method, social and cultural influences on science, and scientific bias, was strongly influenced by their experiences in SSI-based learning environments. Furthermore, multidimensional SSI-based science classes resulted in students having multiple reasoning modes, such as ethical and economic reasoning, compared to data-driven SSI-based science classes. In addition to portraying how participants presented complexity, perspectives, inquiry, and skepticism as aspects of socioscientific reasoning (Sadler et al. in Research in Science Education 37:371–391, 2007), this study proposes the inclusion of three additional aspects for the socioscientific reasoning theoretical construct: (1) identification of social domains affecting the SSI, (2) using cost and benefit analysis for evaluation of claims, and (3) understanding that SSIs and scientific studies around them are context-bound.     

An Evaluation of a Children's Safety Training Programme

This paper reports an experimental evaluation of a children's safety training programme,Kidscape, which aims to increase primary school children's ability to deal with four types of potentially unsafe situation: being bullied, being approached by a stranger, being subject to inappropriate intimacy from a known adult and to pressure from such adults to keep such intimacy secret. Assessments of children's safety awareness were carried out in three schools which used the programme, and in three matched control schools which did not, with children at two age levels, 6 years and 10 years. These assessments of children's awareness were made on three occasions: before, immediately after and 2‐3 months after the training programme for the experimental sample (60 children) and on corresponding occasions for the control sample (60 children). The results revealed a significant improvement in the safety awareness of the experimental (trained) group after training and also a significant difference between the groups, in favour of the trained group. However, an improved performance of the control (untrained) group suggests that factors other than the Kidscape programme itself may influence these differences. Age differences in children's wariness of the four safety situations are also discussed.     

A longitudinal study of learning for a group of indigenous Australian university students: Dissonant conceptions and strategies

Conceptions of learning andstrategies used by 15 indigenous students inthree Australian universities were studiedlongitudinally over three years. Their academicachievements were good, but at a high cost interms of time and effort. In spite of the factthat almost half of the students expressedhigher-order (qualitative) conceptions oflearning in the first year and more in thesecond and third years, all of the studentsreported using highly repetitive strategies tolearn. That is, they did not vary their way oflearning, reading or writing in the beginningof their studies and less than half of them didso at the end of the three years. It is arguedthat encountering variation in ways of learningis a prerequisite for the development ofpowerful ways of learning and studying.     

Context Cues in Early Reading

An investigation was carried out to examine any significant differences in the use of four types of context cues by good and poor readers in the early stages of their reading development. Sentences incorporating proactive and retroactive syntactic, and proactive and retroactive semantic cues were presented in the form of deletions at three levels of difficulty. Sixty-four subjects, 32 of each sex, were drawn equally from the six to seven and seven to eight year age levels and subdivided into groups of good and poor readers. Results indicated that all groups other than the youngest poor readers found the proactive semantic cues the most useful and made miscues displaying semantic associations across cue types. Implications for an understanding of strategies employed in early reading and approaches for instruction are discussed.     

Supervisors’ experiences in supervising higher education students from culturally and linguistically diverse backgrounds during work-integrated learning of health and non-health courses

The growing number of students who are culturally and linguistically diverse (CALD) relative to the host university undertaking fieldwork placements raises questions about how to best support their needs and the needs of their fieldwork supervisors so as to maximize the experience for both parties. This research aims to quantify and compare fieldwork supervisors’ perceptions of CALD versus non-CALD students’ performance during placements, the areas and levels of concern they experience in providing this supervision. Placement supervisors from health and non-health courses affiliated with an Australian University were randomly assigned to a survey containing question sets relating to their experiences in supervising CALD (n = 153) or non-CALD students (n = 168). The survey comprised Likert scale questions assessing “pressure points” to supervision and open-ended questions including strategies fieldwork supervisors typically used to assist students. Using univariate ordinal logistic regression analyses, “speaking” (coefficient, 95% CI 2.1 (1.56, 2.65)), “writing” in English (1.69 (1.17, 2.20)), and “adapting to culture of workplaces” (1.20 (0.71, 1.69)) were perceived by placement supervisors as the top “pressure points” in supervising CALD students. Interaction effects demonstrated that “difficulties in assessing CALD students’ competency” (coefficient, 95% CI?1.14 (?2.27, ?0.01), “feeling competent in supervising students for placements” (1.35 (0.26, 2.45)), and the “perception of lack of support” from either the university or employing organization (?1.70 (?2.83, ? 0.56)) were evident within fieldwork placement of health courses only. These results can assist universities and placement organizations to prioritize resources to address the key areas affecting CALD students’ performance on placements, and to improve supervisors’ experience in supervising CALD students on placements in health courses.

     

An international collaborative investigation of beginning seventh grade students' understandings of scientific inquiry: Establishing a baseline

Although understandings of scientific inquiry (as opposed to conducting inquiry) are included in science education reform documents around the world, little is known about what students have learned about inquiry during their elementary school years. This is partially due to the lack of any assessment instrument to measure understandings about scientific inquiry. However, a valid and reliable assessment has recently been developed and published, Views About Scientific Inquiry (VASI; Lederman et al. [2014], Journal of Research in Science Teaching, 51, 65–83). The purpose of this large-scale international project was to collect the first baseline data on what beginning middle school students have learned about scientific inquiry during their elementary school years. Eighteen countries/regions spanning six continents including 2,634 students participated in the study. The participating countries/regions were: Australia, Brazil, Chile, Egypt, England, Finland, France, Germany, Israel, Mainland China, New Zealand, Nigeria, South Africa, Spain, Sweden, Taiwan, Turkey, and the United States. In many countries, science is not formally taught until middle school, which is the rationale for choosing seventh grade students for this investigation. This baseline data will simultaneously provide information on what, if anything, students learn about inquiry in elementary school, as well as their beginning knowledge as they enter secondary school. It is important to note that collecting data from all of the approximately 200 countries globally was not humanly possible, and it was also not possible to collect data from every region of each country. The results overwhelmingly show that students around the world at the beginning of grade seven have very little understandings about scientific inquiry. Some countries do show reasonable understandings in certain aspects but the overall picture of understandings of scientific inquiry is not what is hoped for after completing 6 years of elementary education in any country.
