Talking modelling: examining secondary science teachers’ modelling-related talk during a model-based inquiry unit

This study examines the classroom talk about models and modelling of two secondary science teachers implementing a model-based inquiry instructional unit. The goal was to better understand the opportunities for explicit metamodeling talk in the science classroom. The findings revealed the ways in which they used language to frame the modelling work of the classroom. Instances of modelling talk were identified in classroom videos, and coded using a framework for metamodeling knowledge. Findings revealed that, while instances of metamodeling talk were common, they were largely implicit. This shows that the teachers were aware and knowledgeable about metamodeling ideas (e.g. the nature of models, process of modelling, etc.), but often did not make these ideas explicit to their students. Such findings suggest a trend of focusing on models of phenomena rather than supporting student engagement in the epistemic practice of modelling for reasoning about phenomena. The findings also revealed specific opportunities for explicit metamodeling talk by the teachers including during share-out sessions and the negotiation of explanation criteria. Further implications for classroom practice and research are discussed.     

The Disposition of Eleventh-Grade Science Students Toward Critical Thinking

The California Critical Thinking Disposition Inventory (CCTDI) was used to assess the disposition of Israeli eleventh-grade science students toward critical thinking according to school type affiliate, scientific level, and gender. Our findings, strongly support (a) the establishment of a baseline reference for disposition toward critical thinking of high school science students; (b) the application of the CCTDI in the context of ongoing science education in different settings; and finally (c) the reliable use of the CCTDI in future research aiming at evaluating the effectiveness of critical thinking (CT) and higher-order cognitive skills (HOCS) oriented instructional goals.

The factor structure and criterion validity of a test for assessment of cognitive abilities. Comparing students in special and regular education

As a consequence of a recent reform of junior secondary education in the Netherlands, instruments for the assessment of cognitive abilities of students who are eligible for special educational support must be designed. In constructing a new test battery contemporary theory on crystallized and fluid intelligence (Gf-Gc theory) was considered. Complete coverage of the factors in Gf-Gc theory was not striven for, because the status of some of these factors in relation to referral to education with special educational support is not entirely clear. The sample in the study consisted of students from regular and special primary as well as secondary education, aged between 11 and 15 years. Approximately two-thirds of the sample was of Dutch origin, whereas the remaining third was of a different ethnic origin. Results show that the factors verbal-crystallized ability, fluid-reasoning ability, spatial-visualization ability and memory capacity can explain the positive correlations between the tests in the battery for the greater part. Students from regular and special education can be distinguished on the basis of their cognitive profiles reasonably accurate, thus supporting the criterion validity of the test battery. Students requiring special educational support are characterized by a significant discrepancy between short-term recall and long-term retention and retrieval.     

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.     

Internationalisation of Business Education: Meaning and implementation

The internationalisation of business has been one of the most prominent features of the second half of the twentieth century, with its pace and breadth touching all elements of the value-adding network. In this environment, the higher education sector has been revising its aims and objectives to incorporate an international dimension to the skills and knowledge development of students. However, interpretation of the educational challenges posed by internationalisation in the form of guidelines that specify how the curriculum might be internationalised, is in its infancy. Despite early efforts, little work has been done to translate this trend into a developmental overview of curriculum delivery. This paper begins by synthesising the literature regarding globalisation, curriculum internationalisation and student learning in higher education. It seeks to bridge the gap between the aims of curriculum internationalisation and the subject curriculum. It applies well-accepted educational principles to the task by presenting a three-stage typology of business curriculum internationalisation. These stages are international awareness, international competence and international expertise. Directions for further research are also provided.     

The AAMD ABS-SE,Part Two: Criterion-related validity in a behavior-disordered sample

The purpose of this research was to determine the diagnostic validity of Part Two of the AAMD Adaptive Behavior Scale-School Edition (ABS-SE) for the classification of behavior-disordered (BD) children. The sample consisted of 66 elementary school students ranging in age from 7-0 through 12-11. There were three groups of subjects: (a) children classified BD; (b) children referred for behavior problems, but not classified; and (c) children in regular classrooms, neither referred nor classified. Teachers completed Part Two of the ABS-SE for all subjects. Validity was investigated for both domain and factor scores, with discriminant analyses yielding significant classification results. Using the domain scores generated by the stepwise discriminant analysis, the overall rate of correct classification was 71.21%; using factor scores, the level of correct classification increased to 77.27%.     

Exploring strategies for online teaching and learning

This paper explores various strategies for creating engaging online learning environments. It describes a framework which identifies and distinguishes between the critical elements needed in the design of online learning: the content of the course, the learning activities and the learning supports. It demonstrates through practical examples how each of these elements can be manipulated in deliberate ways to influence learning processes and outcomes. The paper supports the notion that online courses are best when they arc engineered to take advantage of the learning opportunities afforded by the online technologies, rather than being used as supplements to conventional teaching programs.     

IN-SERVICE TRAINING OF PROFESSIONAL AND PARA-PROFESSIONAL STAFF ININSTITUTIONS FOR THE AGED

An Institutional Resident Quality of Life Project conducted at six institutions throughout Israel during 1994-1997 aimed to: (1) identify and test elements in the life domains of institutional residents that affect their quality of life, and (2) introduce changes in staff attitudes and behavior toward the residents. The article deals with the supplementary training for staff in one of the participating institutions in the project, and the evaluation of this training program. The growing number of elders in the modern world demands accelerated development of community and institutional services. In turn, the growth of these services requires the training of professional and para-professional personnel, with an emphasis on the latter group in light of the more pressing need for day-today caregiving that para-professionals provide. Considerable efforts have been made in Israel in recent years to recruit such workers, train them before they are employed, and deal with various problems once they are on the job. The data gathered during the course of the project illuminated the significant effect of staff-resident relationships on the residents' quality of life. The supplementary training of the staff, moreover, was found to contribute to the improvement of these relationships. A decision was made, therefore, to develop ongoing training programs for professional, and especially, para-professional staff.     

Children-at-risk for poor nutrition: expanding the approach of future professionals in educational institutions

Objectives

To examine how the subject of nutrition is being addressed in the work with children at risk of poor nutrition in educational institutions and what the barriers are which may hinder inclusion of this subject.

Methods

A structured questionnaire was constructed for the purpose of this study and was implemented with 111 students in Israel who are working in their internships in educational institutions with children who are exposed to risk factors of poor nutrition (e.g., parental neglect, lack of knowledge, poverty).

Results

Participants attributed a high level of importance to integrating nutrition-related components in their work. However, the findings indicate less emphasis on nutrition-related components than on psycho-social-educational components, as well as a low level of collaboration with specialists in the area of nutrition. In addition, it was found that knowledge-based barriers and institutional-related systemic barriers may hinder future teachers’ capabilities to incorporate those components despite their favorable approach towards this subject.

Conclusions

The findings illuminate the need to reduce barriers hampering the individual work with children at risk of poor nutrition in educational institutions.

Practice implications

In the training of future teachers, there is a need to advance a bio-psycho-social educational approach incorporating a knowledge base about assessing situations of poor nutrition, including how to advance an interdisciplinary collaboration with specialists in the area of nutrition.
