A Law of Physics in the Classroom: The Case of Ohm’s Law

Difficulties in learning Ohm’s Law suggest a need to refocus it from the law for a part of the circuit to the law for the whole circuit. Such a revision may improve understanding of Ohm’s Law and its practical applications. This suggestion comes from an analysis of the history of the law’s discovery and its teaching. The historical materials this paper provides can also help teacher to improve students’ insights into the nature of science.     

Questions Can Answer Questions About Mechanisms of Preschoolers’ Selective Word Learning

This study examined how inferences about epistemic competence and generalized labeling errors influence children’s selective word learning. Three- to 4-year-olds (N = 128) learned words from informants who asked questions about objects, mentioning either correct or incorrect labels. Such questions do not convey stark differences in informants’ epistemic competence. Inaccurate labels, however, generate error signals that can lead to weaker encoding of novel information. Preschoolers retained novel labels from both informants but were slower to respond in the Inaccurate Labeler condition. When the test procedure was not sensitive to the strength of information encoding, children performed above chance in both conditions and their response times did not differ. These results suggest that epistemic-level inferences and error generalizations influence preschoolers’ selective word learning concurrently.     

Developing ‘Butterfly Warriors’: a Case Study of Science for Citizenship

Given worldwide concern about a decline in student engagement in school science and an increasing call for science for citizenship in New Zealand Curriculum, this study focused on a butterfly unit that investigated how students in a year-4 primary classroom learnt about New Zealand butterflies through thinking, talking, and acting as citizen scientists. The butterfly unit included five lessons. The researchers observed the lessons and interviewed students and the classroom teacher. The students completed a unit evaluation survey after the unit. Findings indicate that the students enjoyed and were interested in activities such as reading about butterflies, learning and using new vocabulary, drawing butterfly life cycles, as well as hunting, tagging and releasing butterflies and publishing the data they had collected on a dedicated website. Through their participation in the unit, students had opportunities to act locally and globally, and to ‘see themselves’ in science through ‘being there’ experience. Units like this have the potential to develop students’ interest for longer-term engagement in science, even those students who may never envision themselves as professional scientists.     

The Use of Tape as a ‘Lead-Medium’

Mathematical circles in the schools of the Federal Republic of Germany are engaged in the examination and discussion of two proposed teaching reforms, the first concerned with the content of teaching and the second with its methods. The proposals stem from the 1968 Conference of Cultural Ministers, a subject of which was the establishment of ‘A Framework of Guiding Principles of Reform’. These principles provide for reforms in mathematics teaching in schools, to start in the school year 1972/73, and preparatory work has been going on in a number of places. The research includes a mathematical project on the theme: ‘Value of Digit Systems’, work on which has been carried out by the Institut für Film und Bild in association with the publishing firm of Ernest Klett.     

‘Am I Like a Scientist?’: Primary children's images of doing science in school

A considerable body of evidence highlights how inquiry-based science can enhance students' epistemic and conceptual understanding of scientific concepts, principles, and theories. However, little is known about how students view themselves as learners of science. In this paper, we explore primary children's images of doing science in school and how they compare themselves with ‘real’ scientists. Data were collected through the use of a questionnaire, drawing activity, and interviews from 161 Grade 4 (ages 9–10) students in Singapore. Results indicate that ‘doing science as conducting hands-on investigations’, ‘doing science as learning from the teacher’, ‘doing science as completing the workbook’, and ‘doing science as a social process’ are the images of learning science in school that most of the students held. In addition, students reported that they need to be well behaved first and foremost, while scientists are more likely to work alone and do things that are dangerous. Moreover, students often viewed themselves as ‘acting like a scientist’ in class, especially when they were doing experiments. Nevertheless, some students reported that they were unlike a scientist because they believed that scientists work alone with dangerous experiments and do not need to listen to the teacher and complete the workbook. These research findings further confirm the earlier argument that young children can make distinctions between school science and ‘real’ science. This study suggests that the teaching of science as inquiry and by inquiry will shape how students view their classroom experiences and their attitudes towards science.     

A Potential Case of Linguistic Prejudice: The Expression of Identity in ‘Black and White’

The existence of a race-based stigma has been well documented among adolescents and young adults within higher educational settings; however, similar studies among students at historically Black universities are rare. Specifically, the ‘acting white’ accusation is a common, and yet seldom openly discussed phenomenon that exist within the African American community. This type of stigma is often relegated to certain characteristics (i.e., behaviors, preferences, etc.) that may defy individual and collective assumptions regarding African Americans. Utilizing nearly 200 student questionnaires, this study identified the extent to which speaking correct English as well as other specific behaviors are associated with being accused of acting white. This process incorporated the use of bivariate correlation and regression models. Findings suggest that speaking correct English as well as the existence of other factors (i.e., preferences in dress, associations, etc.) are significantly related to the accusation. This includes both experiential and nonexperimental student responses. In determining predictor variables, those who experience as well as how they respond to the accusation revealed statistical significance. The study concludes by offering areas of further research as well as suggested policy implications within higher educational settings. This includes an examination of complex and multilayered aspects of identity among minority groups within academic environments.     

The ‘self‐interested’ woman academic: a consideration of Beck's model of the ‘individualised individual’

The work of Ulrich Beck, particularly his concept of the ‘individualised individual’, is increasingly cited by educational social scientists. As yet, there have been few empirical investigations that consider how applicable and relevant is the notion of the ‘individualised individual’ in understanding how people make sense of their lives (for an exception, see Reay, 2003 Reay, D. (2003). A risky business? Mature working‐class women students and access to higher education. Gender and Education, 15(3): 301–317. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]). This paper considers Beck's assertion that social class is of increasingly less importance as society shifts from a first to a second modernity. Interviews were carried out into the career experiences of a group of academic women working in higher education institutions. The conclusions reached suggest that if Beck's theory is to be useful in understanding contemporary actors in contemporary societies then the critical concepts he introduces need to be articulated by researchers in more complex ways.     

Mapping Variation in Children’s Mathematical Reasoning: The Case of ‘What Else Belongs?’

Explaining appears to dominate primary teachers’ understanding of mathematical reasoning when it is not confused with problem solving. Drawing on previous literature of mathematical reasoning, we generate a view of the critical aspects of reasoning that may assist primary teachers when designing and enacting tasks to elicit and develop mathematical reasoning. The task used in this study of children’s reasoning is a number commonality problem. We analysed written and verbal samples of reasoning gathered from children in grades 3 and 4 from three primary schools in Australia and one elementary school in Canada to map the variation in their reasoning. We found that comparing and contrasting was a critical aspect of forming conjectures when generalising in this context, an action not specified in frameworks for generalising in early algebra. The variance in children’s reasoning elicited through this task also illuminated the difference between explaining and justifying.     

Language in Science Classrooms: An Analysis of Physics Teachers’ Use of and Beliefs About Language

The world over, secondary school science is viewed mainly as a practical subject. This may be one reason why effectiveness of teaching approaches in science education has often been judged on the kinds of practical activity with which teachers and students engage. In addition to practical work, language??often written (as in science texts) or oral (as in the form of teacher and student talk)??is unavoidable in effective teaching and learning of science. Generally however, the role of (instructional) language in quality of learning of school science has remained out of focus in science education research. This has been in spite of findings in empirical research on difficulties science students encounter with words of the instructional language used in science. The findings have suggested that use of (instructional) language in science texts and classrooms can be a major influence on the level of students?? understandings and retention of science concepts. This article reports and discusses findings in an investigation of physics teachers?? approaches to use of and their beliefs about classroom instructional language. Direct classroom observations of, interviews with, as well as content analyses of the participant teachers?? verbatim classroom talk, were used as the methods of data collection. Evidence is presented of participant physics teachers?? lack of explicit awareness of the difficulty, nature, and functional value of different categories of words in the instructional language. In conclusion, the implications of this lack of explicit awareness on the general education (initial and in-service) of school physics teachers are considered.     

The ‘German children’ of Mozambique: long-term legacies of a socialist educational experiment

State-led education policies that centre on citizenship formation and are based on socialist-inspired values have been found in many newly independent post-colonial regimes. Such policies have led to a number of educational exchange programmes between developing countries and former ‘Eastern Bloc’ countries. This paper looks at an ambitious secondary school education exchange programme between Mozambique and the former German Democratic Republic in the 1980s. Using Yuval-Davis' three analytical categories of social location, identification and emotional attachment, and ethical and political values, the paper shows how an important part of the identity of former participants in a school exchange programme, who returned to Mozambique in 1988, is built around the concept of being ‘German’ and ‘socialist’. These values of socialist solidarity continue to guide many aspects of participants' lives. However, because in contemporary post-structural adjustment capitalist Mozambique, such values are perceived as a hindrance to contemporary notions of citizenship, these values are lived out mainly in relation to their peer group of fellow ‘German children’.     

The number zero: preschool teachers’ perceptions and teaching practices: a Turkish sample

Children's intuitive understanding of numbers begins early in life, and their numbers-related knowledge influences instructors’ teaching practices. The number zero is more difficult to teach and learn than other numbers. The purpose of this study was to investigate how preschool teachers perceive the number zero and design their teaching practices for it. The participants in this case study were selected through convenience sampling. The findings indicated that the majority of the participating preschool teachers perceived the number zero as a symbol and considered children's age while developing teaching practices.

The teacher as a ‘colony’: a case study of agentive responses to ‘colonising’ education policy in Vietnam

Neo-liberal educational policies that are being implemented globally work to foster competition among schools and teachers, as well as among children. In this situation, teachers must often come to accept the dominant representations of curricular policy developed by higher authorities. In this study, a case study design is used to describe how one school in Vietnam shifted away from this state of ‘colonisation’ by reforming the school under the framework of lesson study for learning community (LSLC). This paper subsequently argues that there is a need for school-level policies that democratise school culture and practices, resisting the negative impacts of colonising policies.     

The International Baccalaureate and ‘growth scepticism’: a ‘social limits’ framework

The number of schools offering the programmes of the International Baccalaureate (IB) hit 3000 in July 2010. Since 2004 the IB has aimed for further growth within a ‘wider access’ and ‘greater impact’ paradigm. A further 7000 schools are expected to be involved by 2020. However, there is now considerable concern about growth, especially within the ‘international school movement’ who see it as compromising quality. This recent phenomenon can be termed ‘growth scepticism’ in the same way economic growth is now questioned as desirable. This paper charts this development and argues there is room for a much wider framework of analysis, viewing the global growth of the IB within a social and moral lens. This paper takes the economist Fred Hirsch’s 1976 Hirsch, F. 1976. The social limits to growth, Cambridge, MA: Harvard University Press. [Crossref] , [Google Scholar] book The social limits to growth as its core theoretical framework, linking growth to potential social externalities such as increased competition and the commercialization of society.     

Pupils’ Image of ‘the Scientist’ among Two Communities in Israel: A comparative study

The image of ‘the scientist’ and its effect on the willingness to be a scientist and to follow a career in science were investigated in two different cultural populations of elementary and junior high school pupils in Israel: Hebrew‐speaking (secular) pupils (N = 390) and Arabic‐speaking Bedouin pupils (N = 185). Five different tools were employed in our investigation (naming scientists, pictorial representation of the scientist (‘Draw‐a‐Scientist‐Test’), statements regarding the characteristics of the scientist, reasons for wanting/not wanting or being able/being unable to be scientists, and sources of knowledge regarding the scientist’s image). The image held by Hebrew pupils was similar to those held by western pupils found in previous research, but some details were more elaborate (due to the fact that many different tools were employed here). However, the image held by the Arabic pupils differed from that found in previous research. This image had a strong ethnical trend, with Golden Age Muslim scientists’ names dominating name lists, and drawings of traditional Muslim figures. Another image found in their drawings was of a scientist admired as a teacher, emphasising the Bedouin school’s formal culture. The theory of modernity will be a useful analytical tool to judge the results of the investigation, whether the population is supposed to be (or is close to) a modern population and whether it does not, definitely, fall under this definition (see Methods and Discussion).     

Minority Students’ Responses to Racism: The Case of Cyprus

While research has focused on the role of racism in (re)producing ethnic/racial inequalities in education, there is very little research that investigates how variability in minority students’ responses to racism can be explained. By using an ecological approach to integrate existing research on actors’ responses to racism, this study finds that researchers have generally neglected factors and processes situated at the micro- and meso-levels of analysis. Qualitative interview data with Turkish–Cypriot children enrolled in schools in the predominantly Greek-speaking part of the Republic of Cyprus are used to investigate their strategies in response to racism and the factors that explain the observed variability in their responses. The findings suggest the importance of and interactions between factors situated at different levels of analysis, including the level of organizations and social groups and face-to-face interactions in explaining variability in young people’s responses to racism.     

Notes and Case Studies: ‘A Live Case Study’

Abstract

The article describes and analyses some of the problems of running a live case study for undergraduate students at a real work place. The case was concerned with decision making in a business organisation in general and with the selection of an advertising strategy for lager in particular.

A discussion about the preparations needed is followed by an analysis of the costs and benefits derived. Learning strategies are briefly outlined and some issues of joint assessment between academics and industrialists are raised The article concludes with a number of findings which, it is hoped, colleagues planning similar exercises will find useful.
