How to Change Students‘ Conceptions of the Epistemology of Science

This paper is subdivided into two sections: In Part I empirical results of students epistemological conceptions of laws, hypotheses, theories, and models are presented as well as their ideas of the pathway of scientific discovery. These results are discussed in relation to research results of different recent publications. In Part II an outline and analysis of a two-year program for explicitly teaching epistemology in a physics course (grade 11-13) is given.     

Pupils’ Attitudes to the Social Implications of Science

Summaries

English

Attitude statements, mostly concerned with the social implications of science, were administered to 2100 pupils of age 14+. The sample was divided into the top 25oO ('GCE') and the next 30‐40oo ('REST') of the ability range and further divided by sex and by coeducation and single‐sex education.

Factor analysis yielded measures of five independent attitudes to (1) science as a school subject (SUBATT) and to its implications (SOCATT) regarding (2) aesthetic/humanitarian issues; (3) practical benefits (4) value to the state for money invested (S) the activities of scientists. The attitude scores were correlated with the biology, chemistry and physics choices made at this age and with liking for these subjects’ teachers. There were 26/60 significant but low overall correlations with physics and chemistry choices, but only 5/30 for biology. A further 26 significant correlations arose either at high or low teacher liking, the former predominating with boys and the latter with girls.

A Kruskal‐Wallis analysis indicated that some attitudes in the ‘GCE’ group were unaffected by the school attended and possibly derived from the media. Adverse attitudes to the social implications of science may be a factor in the swing away from physical science and technology.     

Newton’s Investigation of the Resistance to Moving Bodies in Continuous Fluids and the Nature of ‘Frontier Science’

Newton’s experiments into the resistance which fluids offer to moving bodies provide some insight into the way he related theory and experiment. His theory demonstrates a way of thought typical of 17th century physics and his experiments are simple enough to be replicated by present day students. Newton’s investigations using pendulums were discussed in a previous paper. In this paper Newton’s theory of the resisted motion of falling bodies is outlined, his investigations into the resistance offered to falling bodies by water and the experiments of others into the resistance offered by air are described and some implications for teaching about the nature of science are discussed.

Applying the Science of Learning to the Learning of Science: Newton’s Second Law of Motion

Science teaching and learning require knowledge about how learning takes place (cognition) and how learners interact with their surroundings (affective and sociocultural factors). The study reported on focussed on learning for understanding of Newton’s second law of motion from a cognitive perspective that takes social factors into account. A cognitive refinement instructional approach (CRIA) was used to organise and sequence learning activities, while students were engaged through inquiry and group work. Students’ real-life experiences were used as starting point of the learning sequence. The efficiency of the sequence was determined with the aid of the Force Concept Inventory (FCI) and complemented with the students’ reflections on the sequence, showing their epistemological preferences. The results indicated that a CRIA aided in constructing more coherent scientific knowledge and enhanced understanding, while reducing misconceptions on the topic. In their reflections, the students acknowledged that experiential and experimental evidence, as well as guided formation of a scientific explanatory framework, are foundational for a deeper understanding of the challenging topic.     

Philosophical Approaches of Religious Jewish Science Teachers Toward the Teaching of ‘Controversial’ Topics in Science

This research examines the problems that religious Jewish science teachers in Israeli high schools have in coping with science subjects (such as geological time) which conflict with their religious beliefs. We do this by characterizing the philosophical approaches within Judaism that such teachers have adopted for dealing with such controversy. Thus, we surveyed 56 religious teachers using a Likert‐type questionnaire developed for this research, as well as interviewed 11 teachers to more deeply probe their approaches. In addition, we surveyed 15 religious scientists, so that we could both contrast their views with our teacher samples as well as to better understand their coping strategies when confronted by scientific topics that challenge their beliefs. Results indicated that no single philosophical approach earned overwhelming support from the teachers or scientists. Instead, most of the subjects relate separately to each source of possible conflict in accordance with the philosophical approach that appears to be the most fruitful for resolving such conflicts. Moreover, both the scientists and the teachers felt less conflicted toward the specific subject of geological time, in comparison to issues connected to creation of the earth and (especially) evolution. The teachers did differ from the scientists in their preference toward philosophical approaches which help them better integrate the domains of science and religion. Based on our findings, we are able to suggest a set of strategies to help teachers overcome their difficulties in teaching ‘controversial’ science topics to a religiously oriented student population.     

Science Curriculum in the Market Liberal Society of the Twenty-first Century: ‘Re-visioning’ the Idea of Science for All

The period since the 1960s has seen dramatic change in the nature and practice of science, science education and secondary school education itself. This paper examines changes in the Science for All movement, setting these changes in the context of the societal shift towards market liberalism and the advancement of a new style of individualism. We argue that the climate of today requires a re-focusing of the priorities of secondary school science education, with a new emphasis on what Science for All implies for the education of those who will go on to be our scientific elite.     

Examining Teachers' Hurdles to ‘Science for All’

The goal of this research is to identify science teachers' beliefs and conceptions that play an important role in shaping their understandings of and attempts to enact inclusive science teaching practices. We examined the work products, both informal (online discussions, email exchanges) and formal (papers, unit plans, peer reviews), of 14 teachers enrolled in a master's degree course focused on diversity in science teaching and learning. These emerging understandings were member-checked via a series of interviews with a subset of these teachers. Our analysis was conducted in two stages: (1) describing the difficulties the teachers identified for themselves in their attempts to teach science to a wide range of students in their classes and (2) analyzing these self-identified barriers for underlying beliefs and conceptions that serve to prohibit or allow for the teachers' understanding and enactment of equitable science instruction. The teachers' self-identified barriers were grouped into three categories: students, broader social infrastructure, and self. The more fundamental barriers identified included teacher beliefs about the ethnocentrism of the mainstream, essentialism/individualism, and beliefs about the meritocracy of schooling. The implications of these hurdles for science teacher education are discussed.     

Teachers’ Understanding and Operationalisation of ‘Science Capital’

Across the globe, governments, industry and educationalists are in agreement that more needs to be done to increase and broaden participation in post-16 science. Schools, as well as teachers, are seen as key in this effort. Previous research has found that engagement with science, inclination to study science and understanding of the value of science strongly relates to a student's science capital. This paper reports on findings from the pilot year of a one-year professional development (PD) programme designed to work with secondary-school teachers to build students’ science capital. The PD programme introduced teachers to the nature and importance of science capital and thereafter supported them to develop ways of implementing science capital-building pedagogy in their practice. The data comprise interviews with the participating teachers (n?=?10), observations of classroom practices and analyses of the teachers’ accounts of their practice. Our findings suggest that teachers found the concept of science capital to be compelling and to resonate with their own intuitive understandings and experiences. However, the ways in which the concept was operationalised in terms of the implementation of pedagogical practices varied. The difficulties inherent in the operationalisation are examined and recommendations for future work with teachers around the concept of science capital are developed.     

Putting Sociology First—Reconsidering the Role of the Social in ‘Nature of Science’ Education

Contrasting two examples from 2005, a creationism-trial and a recent textbook, the article shows two different ways of employing social considerations to demarcate science from non-science. Drawing conclusions from the comparison, and citing some of the leading proponents of science studies, the paper argues for a novel perspective in teaching nature of science (NOS) issues, one that grows out of sociological and anthropological considerations of (scientific) expertise. In contrast to currently dominant epistemic approaches to teach NOS, this view makes it possible to incorporate epistemic and social norms in a unified framework that can alleviate presently problematic aspects of NOS modules, and can help students appreciate science as a privileged form of knowledge-production without becoming scientistic. A pilot module to carry out the above is presented and assessed, showing that a broad sociological starting point is closer to the lifeworld of students, and that traditional epistemic considerations need not be compromised.

Science teachers’ perceptions of the appeal of science subjects to boys and girls

Science teachers’ perceptions of the type of subject that appeals to 14 year old pupils were investigated using bi‐polar semantic differential rating scales. It was found that science teachers believe that boys and girls prefer significantly different subject characteristics. Teachers’ beliefs about the subject characteristics preferred by boys are closer to the perceived characteristics of school science, as judged on the same semantic differential scales, than is the case for girls. Teachers perceive the characteristics of school science to be much less attractive to girls. A comparison between the responses from groups of science teachers and pupils revealed that teachers believe that boys’ and girls’ preferences for subject characteristics are more dissimilar than they actually are. Girls’ preferences are closer to those of boys and to the characteristics associated with school science than teachers realize.     

Focusing on the Classical or Contemporary? Chinese Science Teacher Educators’ Conceptions of Nature of Science Content to Be Taught to Pre-service Science Teachers

Drawing from the phenomenographic perspective, an exploratory study investigated Chinese teacher educators’ conceptions of teaching Nature of Science (NOS) to pre-service science teachers through semi-structured interviews. Five key dimensions emerged from the data. This paper focuses on the dimension, NOS content to be taught to pre-service science teachers. A total of 20 NOS elements were considered by the Chinese science teacher educators to be important ideas to be taught. It was also found that among these educators, whether focusing on the classical or contemporary NOS elements in NOS instruction was a prominent controversy. After explaining the criteria for differentiating between classical and contemporary NOS elements, this paper reports the specific NOS elements suggested by Chinese science teacher educators in this study. Afterward, it describes how all educators in this study were categorized in term of NOS content taught by them to pre-service science teachers. In the end, it discusses three factors influencing the decision on NOS content to be taught, i.e., view of the concept of NOS itself, vision of teaching NOS, and belief in general philosophy.     

Utilizing Science Philosophy Statements to Facilitate K-3 Teacher Candidates’ Development of Inquiry-based Science Practice

This study utilized pre-service teachers’ philosophy statements to connect their beliefs for science teaching with inquiry-based constructivist classroom practice. The major findings of this study suggested that before entering the classroom prospective teachers are strongly aligned with inquiry-based, constructivist-based theories, and describe teaching science as a process approach. However, after entering public classrooms the teacher candidates often abandoned those notions of constructivist, inquiry-based science in favor of a more traditional approach to science instruction. This study addresses a method to engage prospective teachers in designing inquiry-based science pedagogy as well as developing their professional pedagogical confidence.
