Philosophy,thought experiments and large context problems in the secondary school physics course

In this paper it is argued that scientific thinking in physics involves the progressive clarification of the relationship between mathematics and physics, as well as the clarification of scientific induction and deduction. Furthermore, the framing of theories and the working out of their consequences involve the exercise of the imagination. One locus of scientific imagination is the thought experiment, primarily understood as a mental device that helps explicate concepts and principles, and unravel paradoxes.

A sound curriculum in physics, however, must also be based on broad principles of education. These principles are first stated and then it is argued that in conjunction with what we have said about scientific thinking we should teach physics in terms of contexts of inquiry. These contexts relate to questions, method, problems, experiments, history, and the large context problem itself. Here we find the clarification of induction and deduction, as well as the proper placing of the thought experiment.

In the appendix it is shown how this contextual approach can be used for the teaching of kinematics. It is claimed that when we teach within the contexts of inquiry, physics is liberated from a specifiable method, and becomes historical, relevant, alive, human and exciting.     

Book Reviews

Abstract

Purpose: Many farmers remain hesitant to implement structured management plans and strategies tailored to address soil health, irrespective of mounting scientific evidence for the credibility of certain soil health indicators, an increase in the reporting of program benefits and progress in communicating these benefits. Hence, the purpose of this research is to better understand the impediments associated with the adoption of such programs.

Design: Non-parametric analysis of a mail-based survey supported with content analysis of landholder comments was used.

Findings: This research highlights that impediments to the adoption of soil health programs are affected by region and that this is likely influenced by the availability, enthusiasm and motivation of surrounding environmental service providers. While the initial investment in soil health management is perceived as an impediment, landholders indicate that production longevity and long-term financial gain are achievable. Education is not viewed as an impediment by landholders, but cannot be ruled out as an impediment due to the increasing complexities of farming and the displayed knowledge of landholders.

Practical implications: Impediments and incentives to the adoption of soil health management plans have been identified. This provides for strategic planning in promotion and adoption of such plans, as well as identifying priority issues of concern.

Originality/Value: In investigating the impediments and incentives associated with adoption of soil health management plans, strategies for adoption can be formulated and pressing areas of concern are identified.     

Exploring the pedagogical features of integrating essential competencies of scientific inquiry in classroom teaching

ABSTRACT

Background: As inquiry-based instruction is not universally implemented in science classrooms, it is crucial to introduce instructional strategies through the use of contextualized learning activities to allow students with different background knowledge and abilities to learn the essential competencies of scientific inquiry and promote their emotional perception and engagement.

Purpose: This study explores how essential scientific competencies of inquiry can be integrated into classroom teaching practices and investigates both typical and gifted secondary students’ emotional perception and engagement in learning activities.

Sample: A case teacher along with 226 typical and 18 gifted students from a suburban secondary school at Taiwan participated in this study.

Design and methods: After attending twelve 3-hour professional development workshops that focused on scientific inquiry teaching, the case teacher voluntarily developed and elaborated her own teaching activities through the discussions and feedback that she received from workshop participants and science educators. Quantitative and qualitative data were collected through activity worksheet, questionnaire, video camera, and tape recorders. Frequency distribution, Mann-Whitney U test, and discourse analysis were used for data analyses.

Results: Case teacher’s teaching activities provide contextual investigations that allow students to practice making hypotheses, planning investigations, and presenting and evaluating findings. Students’ learning outcomes reveal that typical students can engage in inquiry-based learning with positive emotional perception as well as gifted students regardless of their ability level. Both gifted and typical students’ positive emotional perception of and active engagement in learning provide fresh insight into feasible instructions for teachers who are interested in inquiry-based teaching but have little available time to implement such instructions into their classrooms.

Conclusions: The results of our work begin to address the critical issues of inquiry-based teaching by providing an exemplary teaching unit encompassing essential scientific competencies     

Enhancing school HIV and AIDS strategic plan through expanded stakeholder involvement

Abstract

This article focuses on the need for expanded stakeholder involvement as a means of enhancing the Botswana Department of Secondary Education (DSE) HIV and AIDS strategic plan. Research has indicated that the effects of HIV and AIDS on the supply of and demand for education are considerable. Using a questionnaire and interviews, the research has established that the current DSE HIV and AIDS strategic plan lacks comprehensive strategies for preventing HIV spread in schools. Furthermore, the study has shown that there is limited external stakeholder involvement. The study, therefore, has explored how greater success could be realized. The study has concluded that the strategic plan can be improved through expanded external stakeholder involvement at all the stages of the strategic plan. In order to enhance the DSE strategic plan, a stakeholder involvement model is presented.     

Classifying children: a historical perspective on testing and measurement*

ABSTRACT

At the end of the 19th century, children were increasingly seen as measurable and classifiable objects of study on which a scientific approach to education could be based. Two factors fed into the development of this approach: confidence in scientific methods and the expansion of national education systems. Thus, there emerged a confluence of power and science that led to the measurement and classification of children in the name of an efficiently organized social system. This merging of reason, science and efficiency in the goal of classifying children came at a time when the old unitary school system was being declared outdated and coherent teaching units through which scientific methods of learning could be applied were being developed.     

Are secondary school graduates prepared for the studies of natural sciences? – evaluation and analysis of the result of scientific literacy levels achieved by secondary school graduates

ABSTRACT

Background: In Slovakia, no relevant information is available about the scientific literacy levels achieved by secondary school students.

Purpose: The objective of the research was to identify the levels of scientific literacy among students in the last year of grammar school and examine to what extent this determined the subject chosen for a school-leaving exam, which is related to a student’s personal preferences, as well as to the student’s profile and preparation for university education.

Sample: The research sample consisted of 221 students from 17 grammar schools located in various regions of Slovakia.

Design and methods: To identify the level of scientific literacy, we applied the Test of Scientific Literacy Skills.

Results: The students achieved the lowest success rate in the skill focused on the identification of the research design elements and its strengths and weaknesses. A comparably low success rate was also observed in the skill focused on the justification of the conclusions based on quantitative data. Other difficulties were identified in the field of understanding the basics of statistics, thus indicating an insufficient level of mathematical literacy of the students in the abovementioned field. By contrast, the highest success rate was achieved in the skill focused on the correct application of the scientific results for social purposes.

Conclusions: At the end of secondary school studies, the scientific literacy among Slovak students is at the average level. No differences were observed in terms of gender. In terms of the subjects chosen by the students for their school-leaving exams, we observed that those students who took a school-leaving exam in Biology or Chemistry achieved significantly better results in the test. By contrast, the students who reported on Geography and Civics as the subject of their school-leaving exam achieved significantly worse results in the test.     

Developing instruments concerning scientific epistemic beliefs and goal orientations in learning science: a validation study

ABSTRACT

The purpose of this study was to develop and validate two survey instruments to evaluate high school students' scientific epistemic beliefs and goal orientations in learning science. The initial relationships between the sampled students' scientific epistemic beliefs and goal orientations in learning science were also investigated. A final valid sample of 600 volunteer Taiwanese high school students participated in this survey by responding to the Scientific Epistemic Beliefs Instrument (SEBI) and the Goal Orientations in Learning Science Instrument (GOLSI). Through both exploratory and confirmatory factor analyses, the SEBI and GOLSI were proven to be valid and reliable for assessing the participants' scientific epistemic beliefs and goal orientations in learning science. The path analysis results indicated that, by and large, the students with more sophisticated epistemic beliefs in various dimensions such as Development of Knowledge, Justification for Knowing, and Purpose of Knowing tended to adopt both Mastery-approach and Mastery-avoidance goals. Some interesting results were also found. For example, the students tended to set a learning goal to outperform others or merely demonstrate competence (Performance-approach) if they had more informed epistemic beliefs in the dimensions of Multiplicity of Knowledge, Uncertainty of Knowledge, and Purpose of Knowing.     

Scientific literacy in developed and developing countries

The concept of scientific literacy is now widely used to represent goal statements for science education. These tend to be remarkably similar in developing and developed countries. It is argued that, although this is desirable idealistically, a more realistic approach is required in determining priorities, given the differing cultural and economic contexts of science education. Exposure to science and technology varies in developed and developing countries, yet students in both contexts have difficulty defining science. However, the problem of equating science with progress, but not understanding why, is most acute in developing countries, for it leads to blind faith.

Many students in developing countries receive a limited exposure to science, those in developed countries are bombarded, The question for both is what is most important for them to know. The recognition of science as process is offered as a solution.     

Multi-stakeholder process strengthens agricultural innovations and sustainable livelihoods of farmers in Southern Nigeria

Purpose: In this paper, we explore the strategic role of Multi-stakeholder processes (MSP) in agricultural innovations and how it has impacted livelihood assets’ (LAs) capital dynamics of stakeholders in platforms in West Africa.

Design/Methodology/Approach: We demonstrate how LA capitals and socio-economic dynamics induced by MSP can enhance cassava production efficiency but also create opportunities and challenges that influence platform dynamics and impacts. We use a multistage sampling procedure and sustainable livelihood model (e.g. stochastic frontier functions and Tobit regression) to analyse LA capital dynamics of the stakeholders.

Findings: We showed that the LA of the MSP participants (0.72) was found to be significantly higher (χ²?=?3.732, p?Practical implications: We recommend the institutionalization of MSP in the Agricultural Research for Development (AR4D) with more extension follow-up services so as to adequately and appropriately unleash the potentials in social capital networks that enable the development, effective dissemination and adoption of agricultural innovations.

Theoretical implications: This study suggests that soft-transfer of technologies seems to dominate at MSP inception. But at maturity, the results of the struggle between researchers and farmers would lead to co-reaction and community-based research. Consequently, the knowledge and power dynamics that take place within the MSP should be considered the centre of co-construction and platform dynamics.

Originality/Values: The study provided a practical experience on how MSP can be institutionalized in the AR4D programmes to support agricultural innovation systems and foster pro-poor growth and livelihoods.     

Making inquiry-based science learning visible: the influence of CVS and cognitive skills on content knowledge learning in guided inquiry

ABSTRACT

Many science curricula and standards emphasise that students should learn both scientific knowledge and the skills associated with the construction of this knowledge. One way to achieve this goal is to use inquiry-learning activities that embed the use of science process skills. We investigated the influence of scientific reasoning skills (i.e. conceptual and procedural knowledge of the control-of-variables strategy) on students’ conceptual learning gains in physics during an inquiry-learning activity. Eighth graders (n?=?189) answered research questions about variables that influence the force of electromagnets and the brightness of light bulbs by designing, running, and interpreting experiments. We measured knowledge of electricity and electromagnets, scientific reasoning skills, and cognitive skills (analogical reasoning and reading ability). Using structural equation modelling we found no direct effects of cognitive skills on students’ content knowledge learning gains; however, there were direct effects of scientific reasoning skills on content knowledge learning gains. Our results show that cognitive skills are not sufficient; students require specific scientific reasoning skills to learn science content from inquiry activities. Furthermore, our findings illustrate that what students learn during guided inquiry activities becomes visible when we examine both the skills used during inquiry learning and the process of knowledge construction. The implications of these findings for science teaching and research are discussed.     

Exploring the Potential for Students to Develop Self-Awareness through Personalized Learning

Abstract

Personalized learning (PL) and social-emotional learning (SEL) are areas of increasing emphasis in U.S. educational policy and practice. With the goal of examining how these initiatives may be mutually supportive, this exploratory study investigates the potential for a PL experience to help middle school students develop the SEL skill of “self-awareness.” Using qualitative inquiry, we analyze reflective interviews with eleven students engaged in PL using an original self-awareness coding scheme. Our findings offer promising evidence that PL can promote self-awareness, including specific student examples, followed by recommendations for how PL and SEL efforts can be more strategically aligned.     

High school students’ scientific epistemological beliefs,self-efficacy in learning physics and attitudes toward physics: a structural equation model

Background: There are some theoretical evidences that explain the relationships between core beliefs (i.e., epistemological beliefs) and peripheral beliefs (self-efficacy in learning) in the literature. The close relationships of such type of beliefs with attitudes are also discussed by some researchers. Constructing a model that investigates these relationships by considering theoretical and empirical evidences can empower researchers to discuss these relationships more comprehensively.

Purpose: The purpose of this study is to explore the relationships among Turkish high school students’ scientific epistemological beliefs, self-efficacy in learning physics and their attitudes toward physics.

Sample: A total of 632 high school students participated in this study; however, 269 female and 229 male (a total of 498) high school students’ data were used.

Design and methods: Three distinct instruments that measure scientific epistemological beliefs, self-efficacy in learning physics and attitudes toward physics were combined into a unique questionnaire form and it was distributed to high school students. To explore the relationships among these variables, structural equation modeling was used.

Results: The results showed that scientific epistemological belief dimensions uncovered by the nature of knowing (source and justification) significantly and positively related to both self-efficacy in learning physics and attitudes toward other important physics dimensions. Additionally, self-efficacy in learning physics significantly and positively predicted attitudes toward multiple physics dimensions (importance, comprehension and requirement). However, epistemological belief dimensions related to the nature of knowledge (certainty and development) did not have significant impact on self-efficacy in learning physics or attitudes toward physics.

Conclusions: This study concludes that there are positive and significant relationships among Turkish high school students’ scientific epistemological beliefs, self-efficacy in learning physics and their attitudes toward physics.     

Challenging White Jesus: Race and the Undergraduate Bible Classroom

Abstract

In this article, we offer analysis of and propose means of resistance to White Jesus in undergraduate Bible survey courses. White Jesus functions as a proxy for the operation of white normativity in contexts of religious education. Research on a cohort of first-year undergraduate students demonstrates the durability of race as a factor in students’ experiences and outcomes in required Bible courses. After interpreting these findings in light of literature on race, biblical studies, and higher education, we suggest strategic pedagogical interventions that instructors can employ to resist white normativity.     

Teacher students’ dilemmas when teaching science through inquiry

Background: Inquiry-based science education (IBSE) is suitable to teach scientific contents as well as to foster scientific skills. Similar conclusions are drawn by studies with respect to scientific literacy, motivational aspects, vocabulary knowledge, conceptual understandings, critical thinking, and attitudes toward science. Nevertheless, IBSE is rarely adopted in schools. Often barriers for teachers account for this lack, with the result that even good teachers struggle to teach science as inquiry. More importantly, studies indicate that several barriers and constraints could be ascribed to problems teacher students have at the university stage.

Purpose: The purpose of this explorative investigation is to examine the problems teacher students have when teaching science through inquiry. In order to draw a holistic picture of these problems, we identified problems from three different points of view leading to the research question: What problems regarding IBSE do teacher students have from an objective, a subjective, and a self-reflective perspective?

Design &; method: Using video analysis and observation tools as well as qualitative content analysis and open questionnaires we identified problems from each perspective.

Results: The objectively stated problems comprise the lack of essential features of IBSE especially concerning ‘Supporting pupils’ own investigations’ and ‘Guiding analysis and conclusions.’ The subjectively perceived problems comprise concerns about ‘Teachers’ abilities’ and ‘Pupils’ abilities,’ ‘Differentiated instruction’ and institutional frame ‘Conditions’ while the self-reflectively noticed problems mainly comprise concerns about ‘Allowing inquiry,’ ‘Instructional Aspects,’ and ‘Pupils’ behavior.’

Conclusions: Each of the three different perspectives provides plenty of problems, partially overlapping, partially complementing one another, and partially revealing completely new problems. Consequently, teacher educators have to consider these three perspectives.     

Conceptual change: A powerful framework for improving science teaching and learning

In this review, we discuss (1) how the notion of conceptual change has developed over the past three decades, (2) giving rise to alternative approaches for analysing conceptual change, (3) leading towards a multiperspective view of science learning and instruction that (4) can be used to examine scientific literacy and (5) lead to a powerful framework for improving science teaching and learning.     

The educational trajectory of Newly Arrived Migrant Students: Insights from a structural analysis of cultural capital

ABSTRACT

Background: The recent influx of Newly Arrived Migrant Students (NAMS) in Western-European societies poses important educational questions about how best to support migrant students within the education system.

Purpose: We sought to study how elements that are associated with cultural capital – namely a sense of entitlement and strategic knowledge – have relevance to NAMS’ educational trajectories. In studying the process of how cultural capital relates to educational careers, this study argues for a general shift from a resource-focused approach towards a strategy-focused approach to cultural capital.

Sample: We collected data from 33 NAMS from six secondary schools in a city in Flanders (the Dutch-speaking part of Belgium). A maximum difference approach was used: this allowed comparison of NAMS who followed the most academic track (general track) and the least academic track (vocational track) in secondary education in Flanders.

Design and methods: We undertook 33 in-depth biographical interviews during which the NAMS reconstructed their educational trajectories. Data were analysed qualitatively. We used structural approach analysis to identify each narrative’s core structure. These structured fragments were then thematically coded.

Results: Within the categories ‘a sense of entitlement’ and ‘strategic knowledge of the education system’, the analysis detected differences in strategies of action between pupils in the general track and in the vocational track.

Conclusion: The findings offer insights that could support the development of better strategies to guide and support NAMS in education. As NAMS’ integration in the educational system appears to be a stretched and slow process of orientation, studying their trajectory has the potential to deepen our understanding of known mechanisms of the reproduction of inequalities in education.     

From Symphony to Jazz: The concept of strategy in education

This paper considers the derivation of the concept of strategy and its deployment as a management technique to enable organisations to prepare for the future. It then examines the related growth of school development planning and explores the extent to which this can be considered to be strategic. It is then argued that whether or not school development planning is strategic, the use of strategy in organisations is no longer either possible, if it ever was, or appropriate. The paper concludes by proposing an alternative basis for planning derived from a combination of marginal incrementalism and feminist literature on problem solving.     

Achievement goals and classroom goal structures: Do they need to match?

Abstract

It is often assumed that students’ personal achievement goals are most beneficial when they match the goal structures of the classroom, but interaction between achievement goals and goal structures is not well researched. In this study, we aim at providing a nuanced picture of the direct, interaction, and nonlinear effects of achievement goals and goal structures on test performance and autonomous motivation. We used multiple linear regressions, including interaction and quadratic terms, in combination with response surface methodology to analyze questionnaire data from students in Grades 6-10. We found no evidence for a general match effect, and only weak indications of interactions between achievement goals and goal structures. Thus, the match between classroom goal structures and students’ personal goals may be less important for students’ motivation and achievement than previously assumed. Still, based on our results we recommend a focus on mastery structures in the classroom.     

This Issue

Abstract

The tools and techniques associated with distance education can be used to meet a number of social, political, or business goals and their accompanying educational or training objectives. Strategic planning is a means for developing and verifying the fit between distance education and its sponsoring goals. This paper reviews a number of strategic plans and the goals and objectives normally assigned to distance education and distinguishes the terms used in strategic thinking about distance education. This essay examines assumptions about adopting distance delivery of education and training by looking at distance education, not as an objective, but as a strategy that can potentially serve many educational objectives.
