Experts' Views on Using History and Philosophy of Science in the Practice of Physics Instruction

This study examines the views of a representative sample of experts in physics, physics education and history and philosophy of science (HPS) on the incorporation of HPS based materials in physics instruction. The obtained spectrum of views addresses three areas: the rationale to include HPS, the most appropriate ways of doing so, and anticipated difficulties in such a new educational approach. The elicited views, interpreted and categorized, reflect the attitude of the community of science educators in Israeli colleges and universities with regard to the subject. The constructed profiles indicate low awareness of the recent changes in the understanding of learning and the role of HPS in the light of these changes. Such knowledge can guide the activities of those who devote their efforts to constructing and implementing learning materials utilizing HPS contents in science education.     

Cultural differences and students’ spontaneous models of the water cycle: a case study of Jewish and Bedouin children in Israel

The present research aims at pinpointing differences in spontaneous and non-spontaneous mental models of water cycle conceptions of two 4th grade student groups: the Jewish residents of a small provincial town and a group of students from an indigenous Bedouin community. Students’ conceptions were elicited using the Repertory Grid technique as well by being asked to draw “what happens to water in nature?” In later interviews, in addition to answering specially designed open-ended interview questions, the students were also requested to elaborate on their drawings and responses to the Repertory Grid technique. The Bedouin students were found to have richer mental models of water cycle phenomena; their models included more components of the water cycle and were more authentic and connected to other natural phenomena. On the other hand, Bedouin students also employed theological explanations to make sense of water cycle phenomena. These findings, as well as methodological issues relating to spontaneous and non-spontaneous models elicitation are discussed and implications for instruction are offered.     

Whole Class Dialogic Discussion Meets Taiwan’s Physics Teachers: Attitudes and Culture

There is a distance between the power that whole class dialogic discussions (WCDD) may offer to the science class and their use in practice. Teachers’ attitudes toward WCDD are part of the problem. The aims of this study were twofold: (a) to examine Taiwanese physics teachers’ attitudes toward WCDD by considering cultural perspectives and describe how these attitudes changed as a result of a special workshop designed for this purpose, and (b) to report on how these attitudes should be taken into account in designing such workshops in the future. Nine experienced physics teachers participated in the WCDD workshop. The workshop was based on the WCDD model developed by Eshach (2010). Inductive analyses were performed on interviews with the teachers and their students, which were composed of 36 questions and developed specially for the purpose of this study, yielded the following categories: (1) In-school reasons for opposing WCDD—reasons belonging to school ways/tradition of teaching that may cause barriers to WCDD implementation; (2) External Factors—cultural reasons relating to Taiwanese views concerning education in general, which cause barriers to WCDD implementation; and (3) Cognitive aspect—refers to what teachers know about WCDD. The paper concludes with a discussion on what should be done in order to successfully bring WCDD to the Taiwanese physics class.     

SCIENCE TEACHERS’ VOICE ON HOMEWORK: BELIEFS,ATTITUDES, AND BEHAVIORS

Homework (HW) is an integral part of the learning process. Currently, there is renewed interest and controversy about its effectiveness. The present study explores the voices of the science teachers on this matter. Adopting the view that reporting both teachers’ views and actual classroom practices is necessary for obtaining a more complete view of the phenomena, the present study addressed teachers’ views relating to the cognitive, affective, and pedagogical aspects of HW, their in-class practices and behaviors related to HW, and if the views and practices differ. The research was conducted in 3 stages: (a) teachers’ (n = 25) behaviors were examined based on classroom observations of 3 – 5 consecutive lessons, (b) these teachers were interviewed about their beliefs about and attitudes toward HW, and (c) the data from both the observations and interviews were processed into categories and subcategories. The findings revealed a wide range of teachers’ beliefs, attitudes, and behaviors and that teachers hold both positive and negative views simultaneously. In addition, the views for some categories expressed in the interviews concurred with the teacher’s actual classroom behavior; for other categories, disagreements were identified. This research broadens the contemporary horizons regarding HW and may contribute to those who wish to work with teachers making HW more effective.

     

Do Junior High School Students Perceive Their Learning Environment as Constructivist?

The purpose of this study is to examine the manner in which the features of a constructivist learning environment, and the mechanisms at its base, are expressed in junior high school students’ conceptions. Our research is based on an integration of quantitative and qualitative approaches, deigned to provide a wider ranging and deeper understanding. Eight hundred and forty eighth- and ninth-grade students from over 15 schools participated in the study. Of the 840 students who completed the questionnaire, the explanations of 200 well-written questionnaires were further analyzed qualitatively. The findings of the study are presented in terms of the four scales employed in the CLES, namely the autonomy scale, the prior knowledge scale, the negotiation scale, and the student-centeredness scale. The quantitative results achieved here concur with parallel studies conducted around the world. The findings indicate that a considerable portion of the students perceive their learning environment as a constructivist one and report positive attitudes toward the way they are being taught. In terms of the qualitative results, however, it appears that in some cases, the students’ explanations reveal that in fact, and contrary to the bare quantitative results, some students do not perceive their learning environment as being constructivist. This raises the question of whether the fact that students recognize the factors associated with constructivist teaching is indeed an indication that such teaching exists in practice. This finding emphasizes the importance of combining qualitative and quantitative methods for arriving at a balanced view of classroom occurrences.     

School principals as mediating agents in education reforms

School principals may be seen as mediating agents, standing at the school doorstep, between the extra-school and intra-school worlds. The principals’ mediating role becomes more crucial during a time of education reform, which involves external demands on the one hand, and teachers’ resistance to these demands on the other. This study explores how principals mediate between the demands of a national reform policy and teachers’ attitudes and needs. In this qualitative study, 59 school principals were interviewed. Findings from the data analysis indicated that principals used two complementary mediation strategies: (1) mobilising the teachers towards the reform and (2) mobilising the reform towards the teachers. The mediating strategies used by principals are discussed, suggesting practical implications and further research avenues.     

‘Digital natives’: Honour and respect in computerized encounters between Israeli Jewish and Arab children and adult learners

In Israel's Multigenerational Connection Program (MCP), children instruct adults in computer and Internet use. Taking children's advantage in digital literacy as a given, the study examines their generational status in computerized encounters that MCP creates in two schools, one Jewish and one Arab. The data were gathered by means of qualitative participant observation. The results suggest that the family–community‐based habitus is reflected in the interpretation of the program by the computer teacher at each school, who, by ‘importing’ it to MCP, encouraged relations of respect or honour between children and adults. The significance of these relations, rooted in ethno‐national relations between the groups, transcends the global discourse about the uniformity of the generational digital divide. While the Arab group's ambivalence toward MCP weakened the children's status, the Jewish children attained empowerment as young teachers. The conclusions focus on the implications for intergenerational relations and children's self‐image of the preservation of the Arab honour‐contingent habitus in a Western educational context—a self‐chosen strategy that may widen the digital divide between Arab and Jewish children.     

Privatisation by the Back Door: the case of the higher education policy in Israel

The purpose of this study is to seek to understand the process of privatisation and deregulation of Israel's higher education system which had been until the late 20th century predominantly public. Since 1994, public and governmental agencies became major clients of private universities. Thus the public sector played a major role in the expansion of international universities and in the operation of their academic programmes and became their major financial source. This partnership between the public and the private sector could be explained by the following: the increased demand for higher education by native born Israelis and the large flux of immigrants from the former USSR and Ethiopia on the one side, and the socialist ideology which deeply rooted in the Israeli society, to enable for everyone who wishes to attain higher education to find a place in the undergraduate system (particularly the population of the developmental towns and minority groups) on the other, pushed the Israeli government to expand its boundaries. Israel's public universities have been subjected to relax admissions requirement, which they refused to do. Another reason is the increasing demand from the public service in general and particularly from the education service that having a BA degree would increase the teacher salary and it does not matter whether the degree comes from an Israeli university(with its higher standards) or from a branch of an international university(with its lower standards). That explains the expansion and diversification that occurred in the higher education system in Israel. The 1998 Branches Act stipulating that any overseas institution intending to open an off shore branch must obtain a licence from the Council of Higher Education. The new regime demonstrates the paradox in higher education policy, on one side privatisation by the backdoor, on the other, regulation and control by the Israeli government.     

Misconception of sound and conceptual change: A cross‐sectional study on students' materialistic thinking of sound

There is a concern that materialistic thinking—meaning the tendency to attribute a set of matter‐like properties to nonmatter concepts—is one of the central barriers that students face in the journey toward understanding scientific concepts. The cross‐sectional study presented here used the Sound Concept Inventory Instrument (SCII) (Eshach, [ 2014 ], Physical Review Physics Education Research, 10, 010202) to examine how Taiwanese students (N = 717: Grade 7 to undergraduate level) associate the nonmaterial concept of sound with this set of (erroneous) materialistic properties and/or with the (correct) scientific view. Its results show that students in all academic level groups associated sound, at least to some extent, with all of the materialistic properties defined in the instrument. Grades 7–9 evidenced the greatest amount of materialistic thinking, followed by Grade 11, with the lowest levels of materialistic thinking being shown by Grades 10 and 12, as well as university students. We also found that the respondents' confidence in the materialistic view they expressed was high. The results suggest that the extent to which students associate sound with materialistic thinking is not ordered by academic level, but was rather influenced by the immediate relevance of each group's recent curriculum to the topic of sound. This article concludes by examining the results through the lens of several different theories of conceptual change, and by making suggestions, in light of these results, for how the teaching of sound concepts might be improved.
