Understanding Scientific Methodology in the Historical and Experimental Sciences via Language Analysis

A key focus of current science education reforms involves developing inquiry-based learning materials. However, without an understanding of how working scientists actually do science, such learning materials cannot be properly developed. Until now, research on scientific reasoning has focused on cognitive studies of individual scientific fields. However, the question remains as to whether scientists in different fields fundamentally rely on different methodologies. Although many philosophers and historians of science do indeed assert that there is no single monolithic scientific method, this has never been tested empirically. We therefore approach this problem by analyzing patterns of language used by scientists in their published work. Our results demonstrate systematic variation in language use between types of science that are thought to differ in their characteristic methodologies. The features of language use that were found correspond closely to a proposed distinction between Experimental Sciences (e.g., chemistry) and Historical Sciences (e.g., paleontology); thus, different underlying rhetorical and conceptual mechanisms likely operate for scientific reasoning and communication in different contexts.

Measuring clearance mechanics based on dynamic leg length

The aim of this study was to quantify clearance mechanics during gait. Seventeen children diagnosed with hemiplegic cerebral palsy underwent a three-dimensional gait analysis evaluation. Dynamic leg lengths were measured from the hip joint center to the heel, to the ankle joint center and to the forefoot throughout the gait cycle. Significant asymmetry was observed during stance, initial and terminal swing phases, where the hemiplegic limb was found shorter by using a paired t-test at 51 sample points (p < .05). The hemiplegic side was restricted in achieving maximal length during terminal swing. The ratio between the maximal dynamic leg length during the stance phase to minimal dynamic leg length during the swing phase was found higher on the non-involved side and lower on the hemiplegic side (p < .05). Quantifying clearance mechanics based on dynamic leg length can provide an additional insight into the analysis of gait patterns and might assist in detecting time of abnormal kinematic deviations.     

Students’ reaction to classroom discipline in Australia,Israel, and China

This study investigates the extent to which students from Australia, Israel, and China report that their teachers’ classroom disciplinary behaviour affects their attitudes towards schoolwork and the teacher. They also report how justifiable a teacher's intervention appeared. In all three settings, both punishment and aggression relate significantly to the level of students’ distraction and negative affect towards the teacher. Teachers’ recognition of responsible behaviour and discussion with students relate to less distraction and greater belief that the intervention was necessary. Hinting and the involvement of students in classroom discipline decision making relate to a stronger belief that the disciplinary actions taken are warranted. Implications are discussed.     

Meaningful learning in the cooperative classroom

Meaningful learning is based on more than what teachers transmit; it promotes the construction of knowledge out of learners' experience, feelings and exchanges with other learners. This educational view is based on the constructivist approach to learning and the co-operative learning approach. Researchers and practitioners in various countries and settings seek ways to incorporate these approaches to create meaningful learning in the multicultural classroom and in the co-operative learning classroom. This article presents some of the ideas, studies and methods that signal a major shift of emphasis in education from product to process.     

Power and positionality: negotiating insider/outsider status within and across cultures

Early discussions of insider/outsider status assumed that the researcher was predominately an insider or an outsider and that each status carried with it certain advantages and disadvantages. More recent discussions have unveiled the complexity inherent in either status and have acknowledged that the boundaries between the two positions are not all that clearly delineated. Four case studies - a Black woman interviewing other Black women, Asian graduate students in the US interviewing people from ‘back home’, an African professor learning from African businesswomen, and a cross-cultural team studying aging in a nonWestern culture - are used as the data base to explore the complexities of researching within and across cultures. Positionality, power, and representation proved to be useful concepts for exploring insider/outsider dynamics.     

Informal Counselling Services in Israel: A Challenge for the School Counsellor

This article focuses on the characteristics of informal counselling services (such as young people's counselling services or telephone counselling services) in Israel and gives examples of existing services. Manifest characteristics of the counselling services and psychological therapy in the public formal systems and informal systems, as well as a survey of updated literature on the subject of community voluntary psychological counselling services is presented. The informal counselling services are a challenge for school counsellors as supplementary to additional services given in school and offer the possibility of the integration of school counsellors into these programmes.     

Learning ability, socioeconomic status, and student placement for undergraduate studies in Israel

Choice of institution and field of study for a bachelor’s degree in Israel was found essentially meritocratic although influenced by socioeconomic status (SES) as well. As expected, students of higher ability attend universities and those of lower apply to academic colleges. However, among students of higher ability, those of higher SES opt for prestigious professions, such as medicine and law, or natural or social sciences, while those of lower SES choose economics and management, computer science, paramedical professions, and engineering. For students of lower learning ability, the differentiating effect of SES is smaller. Those of higher SES prefer university to college, even if they have to study in a less prestigious field, such as education or the humanities. On the other hand, students of lower ability and lower SES apply to colleges for studies such as education, social sciences, computer science, economics and management, and engineering. Overall, students who master financial resources and higher cultural capital prefer more ‘theoretical’ fields in a more extended course of study, while students of lower SES assume more ‘practical’ studies, which will enable them a faster entry to paying positions on the job market.
