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.     

Cognitive load imposed by ultrasound‐facilitated teaching does not adversely affect gross anatomy learning outcomes

Ultrasonography is increasingly used in medical education, but its impact on learning outcomes is unclear. Adding ultrasound may facilitate learning, but may also potentially overwhelm novice learners. Based upon the framework of cognitive load theory, this study seeks to evaluate the relationship between cognitive load associated with using ultrasound and learning outcomes. The use of ultrasound was hypothesized to facilitate learning in anatomy for 161 novice first‐year medical students. Using linear regression analyses, the relationship between reported cognitive load on using ultrasound and learning outcomes as measured by anatomy laboratory examination scores four weeks after ultrasound‐guided anatomy training was evaluated in consenting students. Second anatomy examination scores of students who were taught anatomy with ultrasound were compared with historical controls (those not taught with ultrasound). Ultrasound's perceived utility for learning was measured on a five‐point scale. Cognitive load on using ultrasound was measured on a nine‐point scale. Primary outcome was the laboratory examination score (60 questions). Learners found ultrasound useful for learning. Weighted factor score on “image interpretation” was negatively, but insignificantly, associated with examination scores [F (1,135) = 0.28, beta = ?0.22; P = 0.61]. Weighted factor score on “basic knobology” was positively and insignificantly associated with scores; [F (1,138) = 0.27, beta = 0.42; P = 0.60]. Cohorts exposed to ultrasound had significantly higher scores than historical controls (82.4% ± SD 8.6% vs. 78.8% ± 8.5%, Cohen's d = 0.41, P < 0.001). Using ultrasound to teach anatomy does not negatively impact learning and may improve learning outcomes. Anat Sci Educ 10: 144–151. © 2016 American Association of Anatomists.

Cross‐national Similarities and Differences in Employee Perceptions of Issues in the Work Environment

This exploratory study examines cross‐national similarities and differences in employee perceptions of issues in the work environment in 17 organizational work settings in seven Asia‐Pacific countries; Australia, Malaysia, New Zealand, Singapore, South Korea, Taiwan, and the United States. Employees at these 17 sites indicated their degree of agreement with statements about 60 work environment issues which previous research has shown impact performance. Resulting data were compared using coefficients of concordance as described by Gibbons (1971) at three levels of analysis. Analysis indicated that differences and similarities in responses did not reflect those one would expect to find based on previous well‐known research concerning cultural differences in those same countries (Hall, 1976; Hofstede, 1980, 2001). This suggests that relying primarily on national cultural differences is not a sufficient guide for the design of performance improvement interventions in various countries and that other context factors need to be taken into account. Possible hypotheses for future research are offered.     

The role of word recognition,oral reading fluency and listening comprehension in the simple view of reading: a study in an intermediate depth orthography

Empirical research has provided evidence for the simple view of reading across a variety of orthographies, but the role of oral reading fluency in the model is unclear. Moreover, the relative weight of listening comprehension, oral reading fluency and word recognition in reading comprehension seems to vary across orthographies and schooling years. This study aims to examine the direct effects of these three variables on reading comprehension and to test for the existence of indirect effects of word recognition and listening comprehension on reading comprehension via oral reading fluency in European Portuguese, an orthography of intermediate depth. A sample of 264 students was assessed at the end of grades 2 and 4. Structural equation modeling analyses indicated that listening comprehension, word recognition and oral reading fluency predicted reading comprehension in both grade 2 and grade 4. Moreover, the three variables measured in grade 2 predicted later reading comprehension in grade 4. Listening comprehension was always the strongest predictor. Oral reading fluency mediated the relationship between word recognition and reading comprehension, but it was not a mediator variable in the relationship between listening comprehension and reading comprehension. These findings indicate that, similarly to what has been found for other orthographies, the simple view of reading is a valid framework to account for reading comprehension variability in European Portuguese and that interventions to increase reading comprehension levels should focus on word recognition, fluency, and, especially, listening comprehension.     

The Financing of Extension Services: A Survey Among Rural Youth in Greece

Abstract

Since its establishment in the early 1950s, the Greek Extension Service has undergone considerable changes. Especially after 1981, a bureaucratic–administrative role related to the implementation of the CAP has been undertaken. In parallel, in the international scene, governments have started experimenting with various cost-recovery mechanisms for extension. In front of such challenges, at both national and international levels, the current work intends to explore the willingness of young rural inhabitants to pay for advisory services. Drawing data from a large-scale survey and utilising probit analysis, the decomposition of the marginal effects of a series demographic, socioeconomic and spatial characteristics and information needs upon willingness to pay for extension is presented. The results show that under preconditions cost-recovery mechanisms may be employed in Greece; furthermore, it is argued that the Extension Service has to be restructured–reoriented.
