Assessing the Nature of Science: What is the Nature of Our Assessments?

This paper discusses the nature of the instruments used to assess students' and teachers' conceptions of the nature of science during the last four decades. Two salient points emerge from critically reviewing the various research emphases and associated assessment instruments specifically related to the nature of science. The first is to question the validity of much of the research presented on the grounds that (a) assessment instruments are interpreted in a biased manner, and (b) some assessment instruments appear to be poorly constructed. Although such comments are well founded, it is important to note that the research conclusions were unusually uniform regardless of the particular instrument used in an investigation. The second point is a more critical concern about the traditional paper and pencil approach to the assessment of an individual's understanding of the nature of science. Although not a new insight, discrepancies between the interpretation of a written response to a traditional instrument (e.g., multiple choice assessment) and the intent of the respondent have been well documented. It is suggested that the current educational research shift toward more qualitative, open-ended approaches to assessment of individuals' understanding (of any concept) be applied to the assessment of individuals' nature of science conceptions.     

The Primacy of Cognition – or of Perception? A Phenomenological Critique of the Theoretical Bases of Science Education

This paper is a phenomenological critique of a particular trend in educational research and practice, which is identified as cognitivism. The basic feature of this trend is a one-sided and exclusive focus on conceptual cognition and concept formation, with a simultaneous neglect of sense experience. It is argued that this kind of thinking is the result of the reception by education of epistemological theories, which have an objective alien to that of education, which is the all-round development of human personality. The discussion draws mainly upon the philosophies of Dewey, Husserl and Merleau-Ponty. It is argued that present, mainstream theories of science education need to be complemented with phenomenological perspectives. This would make the transition from immediate lifeworld experience to the idealizations of scientific theories less difficult for students. It would also contribute towards less alienation between man and nature.     

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.     

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.     

Tacit Knowledge in Expert Coaching: Science or Art?

Effective coaching is a mixture of pedagogy and principles of sciences, e.g., motor skill acquisition, sociology, and physiology, often referred to as the science of coaching. Instinctive or intuitive coaching has often been incorrectly viewed as the art of coaching. More important should be how coaches develop knowledge, how they access that knowledge at the appropriate times and how this affects their decision-making process. The study of expert coaches should allow inferences to be drawn from their development and applied to coach education. This article intends to clarify coaching expertise and examine the role of tacit knowledge within coaching. The lack of a clear development pathway for aspiring expert coaches is a clear indicator that the current coach education system needs review. Any effective education system should be based on knowledge and understanding rather than mimicry and the implications for the future of coach education are considered.     

Science Instructors’ Perceptions of the Risks of Biotechnology: Implications for Science Education

Developing scientifically literate students who understand the socially contextualized nature of science and technology is a national focus of science education reform. Science educators’ perceptions of risks and benefits of new technologies (such as biotechnology) may shape their instructional approaches. This study examined the perceived risk of biotechnology of four groups of science educators: pre-service science teachers, in-service science teachers, biology graduate teaching assistants, and biology professors (n = 91). Data sources included a survey instrument and card sort task designed to determine the respondents’ structure of risk perception and factors contributing to this structure. The perceptions of the four educator groups were compared and contrasted along these dimensions. Results showed that the teacher groups were similar along many aspects of risk perception, but university professors were more likely to view the more subtle “gray areas” between biotechnology risks. The results are discussed in the context of understanding teacher risk perception on science pedagogical practice as well as the role of content knowledge and teaching experience on risk perception formation.     

Constructivism in School Science Education: Powerful Model or the Most Dangerous Intellectual Tendency?

This paper explores and challenges a numberof the assumptions and claims commonly associated with a constructivist approach to school scienceeducation, e.g., that constructivist ideas aboutlearning require a progressive pedagogy or that`active learning' demands engaging students withpractical activities. It suggests that constructivistideas have a particular appeal within primaryeducation because they help to justify classroompractices and activities that primary school teachers,for a variety of other reasons, regard as important.It is suggested that the recent dominant emphasis uponconstructivism in science education has narrowed boththe professional and the research agenda relating toschool science teaching. The paper argues for greaterclarity and precision when referring to constructivistideas in science education and for a betterunderstanding of the role that learning theoriesshould play in influencing the ways in which scienceis taught in schools.     

Adolescents' Declining Motivation to Learn Science: Inevitable or Not?

There is a growing awareness that science education should center not just on knowledge acquisition but developing the foundation for lifelong learning. However, for intentional learning of science to occur in school, out of school, and after school, there needs to be a motivation to learn science. Prior research had shown that students' motivation to learn science tends to decrease during adolescence [Anderman and Young [1994] Journal of Research in Science Teaching 31: 811–831; Lee and Anderson [1993] American Educational Research Journal 30: 585–610; Simpson and Oliver [1990] Science Education 74: 1–18]. This study compared 5th through 8th grade students' self‐reported goal orientations, engagement in science class, continuing motivation for science learning, and perceptions of their schools' and parents' goals emphases, in Israeli traditional and democratic schools. The results show that the aforementioned decline in adolescents' motivation for science learning in school and out of school is not an inevitable developmental trend, since it is apparent only in traditional schools but not in democratic ones. The results suggest that the non‐declining motivation of adolescents in democratic schools is not a result of home influence but rather is related to the school culture. © 2010 Wiley Periodicals, Inc., J Res Sci Teach 48: 199–216, 2011     

Transnationalism in the Australian Curriculum: new horizons or destinations of the past?

Educationally, it is arguable that transnationalism has been primarily framed around course delivery by educational institutions within international contexts. However, it is a more complex notion, incorporating ideas such as global citizenship and intercultural understanding. Consequently, if the Australian Curriculum is the national substantiation of Australia's educational priorities, designed to prepare young Australians for a globalised future, it should reflect such transnationalist elements. This paper contends that, despite contrary impressions, the Australian Curriculum is more of a protective reinforcement of older conceptions of a ‘Western’ community than one centred on forward-looking global principles. Its codifications dominate at the cost of acknowledging other points of reference that represent a collective transnational sensibility, and thus it embodies a lost national opportunity. Recent criticisms that the Australian Curriculum fails to adequately reflect ‘Western’ civilisation are ill-founded, as they ignore the strong presence of ‘Western’ intellectual constructs throughout the Australian Curriculum's design and content.     

Māori in the Kingdom of the Gaze: Subjects or critics?

For Māori, a real opportunity exists to flesh out some terms and concepts that Western thinkers have adopted and that precede disciplines but necessarily inform them. In this article, we are intent on describing one of these precursory phenomena—Foucault’s Gaze—within a framework that accords with a Māori philosophical framework. Our discussion is focused on the potential and limits of colonised thinking, which has huge implications for such disciplines as education, among others. We have placed Foucault’s Gaze alongside a Māori metaphysics and have speculated on the Gaze’s surveillant/expectant strategies with some key Māori primordial phenomena in mind, such as ‘te kore’ (nothingness) and ‘āhua’ (form). We posit the Gaze as an entity and thus aim to render it more relevant to Māori, so that it can be addressed appropriately. We also (but relatedly) preface that discussion by theorising on some of the challenges that confront us as Māori authors in even referring counter-colonially to the Gaze. Whilst we do not seek to destabilise the Gaze by positing it as a metaphysically based entity, we do hint at the possibility that critical indigenous philosophy may even for a short time bring the Gaze into focus for Māori. By introducing an awareness of an alternative (Māori) metaphysics, we may have unsettled the self-certainty of the Gaze.     

Teacher or Examiner? The Tensions between Formative and Summative Assessment in the Case of Science Coursework

The aim of the reported study was to explore how science teachers made sense of their roles and responsibilities in teaching and assessing science coursework. The focus was on the teacher assessment, the feedback that teachers gave to students and, how they perceived their role when they taught and assessed students’ science coursework reports. The research methodology included observation of science lessons, collection of marked students’ reports and two interviews with each of the nine participant teachers. Two cases of teachers are considered as representative of the participant teachers and their perceptions and practices are compared and contrasted. Teachers either adopted the role of the examiner or combined the role of the teacher with that of examiner. They distinguished marking of science theory exercises from marking of coursework and, teaching theory from teaching investigations, on the basis that the grade they assigned to coursework contributed to the total grade for external exams. A key conclusion is that teaching and assessment of science coursework need to re-focus on learning. The study calls for changes in public policy for summative assessment to place more reliance on teachers’ assessments and secondly, for changes in school practices in formative assessment for teachers to support students to learn in the case of science coursework.
