Controversial Conversations in Science: Incorporating the Science “Sex Box”

Science classrooms—and science textbooks—are proving to be challenging spaces for education that contradicts abstinence-only-until-marriage (AOUM) sex education. However, science educators can teach against this knowledge in a way that is critical of oppressive language. In fact, having explicit dialogue about gender identities and sexual orientation can help uncover oppressive cultural attitudes and help science educators challenge universal views of the human body. This article examines two narratives that use a pedagogic practice to help them teach in AOUM environments. The first narrative discusses personal experiences of the author as a science teacher and the dilemmas faced by including what I call a “sex box” in a life science class. The second narrative discusses an excerpt from a research study conducted with life science teachers in which a participant uses this same method. The purpose of this discussion is to help expose the science classroom as a place to have meaningful discussions, even with policies and cultures that do not support the discussion of safe sex for minority human sexualities.¹ This article suggests future science teachers and present teachers alike can advocate for the incorporation of national standards that counteract overtly discriminatory policies.     

Assumption of the burden: Science or criticism?

This article adjudicates the claim to science made by current researchers in speech communication. It argues the point that contemporary research is best characterized as criticism, and that the cause of research in the field would be best advanced if scholars engaged in the enterprise of discourse analysis and conversation analysis regarded themselves as critics and made themselves subject to criticism as such.     

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.     

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.     

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.     

MATAL: the Israel Elementary Science Project‐‐a Retrospective

Summaries

English

In this article, the authors reflect on the development and implementation of the Israel Elementary Science Project (MATAL). The MATAL project, initially established in 1968, used British and American programmes as its foundation, but so modified them that they became applicable to the needs of less developed countries. The authors describe the structure and content of their project, as well as their work in teacher training and the development of ancillary and enrichment programmes. It is hoped that the Israeli experience in developing an elementary school science curriculum will be of interest and potential benefit to curriculum workers in other countries also.     

Science education reform: What's wrong with the paradigm?

From previous and current efforts at science education reform, the author teases out a certain culture of reform, a set of assumptions about educational change that are no longer (if they ever were) appropriate to another task, namely managing change. With reference to a group of programs in undergraduate science instruction that work, she finds the research model, the preference for innovation, the dependence on short-term outside funding, and above all, the seeking after some universal curriculum or set of pedagogies that will solve the problem for all time, to be naive in terms of the reality and the politics of change. She would substitute what Gerald Holton in A Nation at Risk, Revisited calls cumulative improvement, and ends with some suggestions as to how such a model could be applied to the organization of college-level instruction in science.This is a portion of Chapter 1 of the bookPrograms That Work; The Implementation Challenge.

Elementary Science Methods Courses and the National Science Education Standards: Are We Adequately Preparing Teachers?

Despite the apparent lack of universally accepted goals or objectives for elementary science methods courses, teacher educators nationally are autonomously designing these classes to prepare prospective teachers to teach science. It is unclear, however, whether science methods courses are preparing teachers to teach science effectively or to implement the National Science Education Standards (National Research Council, 1996). Using the Science Teaching Standards as a framework for analysis, this research proceeded in two phases. During the first phase, the elementary science methods courses, perspectives, and practices of six science teacher educators were examined to determine similarities and differences in the course goals and objectives, overall emphases, and their efforts to prepare their students to implement the Science Teaching Standards. The second phase of the study investigated the elementary science methods courses of a national sample of science teacher educators as reflected in their course syllabi. It was found that universal inclusion of content related to the Science Teaching Standards does not exist, nor are there clear linkages between course goals, activities, and assignments.     

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.     

Investigating Omani Science Teachers’ Attitudes Towards Teaching Science: the Role of Gender and Teaching Experiences

A 30-item questionnaire was designed to determine Omani science teachers’ attitudes toward teaching science and whether or not these attitudes differ according to gender and teaching experiences of teachers. The questionnaire items were divided into 3 domains: classroom preparation, managing hands-on science, and development appropriateness. The questionnaire was administered to 139 randomly selected science teachers who teach science in grades 5–10. The sample consisted of 72 male teachers and 67 female teachers, 57 teachers with teaching experience between 1 and 5 years and 82 teachers with teaching experience of 6 and more years. The sample was selected from 7 schools in 1 Educational Governorate in the Sultanate of Oman. The questionnaire reliability was calculated by an internal consistency method, using Cronbach’s alpha, which gave the value of 0.73 for all the items. The findings indicated that science teachers’ attitudes toward teaching science were positive. Furthermore, the results showed that there were statically significant differences in teachers’ attitudes due to gender in favor of the female teachers and in teaching experience in favor of teachers with long experience. The study proposed some recommendations to improve the science teachers’ attitude, especially male teachers towards science teaching. Paying more attention to in-service professional development programs, encouraging new teachers to attend some classes to observe experienced colleagues, and finally rewarding teachers morally, socially, and financially are some of these recommendations.     

Science Letters:On the critical radius in generalized Ostwald ripening

INTRODUCTION A polydisperse precipitate produced by nuclea-tion in a metastable supersaturated solution is far from thermodynamic equilibrium, i.e. a state of minimal free energy. A decrease of free energy is accom-plished by a coarsening of the precipitate which es-sentially reduces the surface free energy with respect to the surrounding solution. The process is called Ostwald ripening and is a direct consequence of the Kelvin effect (Adamson and Gast, 1997), that is the higher solubi…     

“I Have Seen the Opportunities That Science Brings”: Encouraging Girls to Persist in Science

Women are underrepresented in science careers. To overcome this, it is important to explore how to encourage girls to continue to study science. This intervention involved girls aged 12–14 attending interactive science sessions at a university. Girls completed questionnaires before and after the session. Through the intervention, girls became more likely to believe they could succeed in science and saw it as both more useful and interesting. However, the timing of this intervention appeared to be too late. Many girls had already decided on a career and stated that they would be unlikely to continue to study science if it was not needed in their chosen career.     

Science Teachers’ Thinking About the Nature of Science: A New Methodological Approach to Its Assessment

This paper describes Spanish science teachers’ thinking about issues concerning the nature of science (NOS) and the relationships connecting science, technology, and society (STS). The sample consisted of 774 in-service and pre-service teachers. The participants responded to a selection of items from the Questionnaire of Opinions on Science, Technology & Society in a multiple response model. These data were processed to generate the invariant indices that are used as the bases for subsequent quantitative and qualitative analyses. The overall results reflect moderately informed conceptions, and a detailed analysis by items, categories, and positions reveals a range of positive and negative conceptions about the topics of NOS dealt with in the questionnaire items. The implications of the findings for teaching and teacher training on the themes of NOS are discussed.     

Mäori in the Science Curriculum: Developments and possibilities

The aim of this paper is to examine the current state of development of Mäori science curriculum policy, and the roles that various discourses have played in shaping these developments. These discussions provide a background for suggestions about a possible future direction, and the presentation of a new concept for Mäori science education (note that in this paper this phrase refers to science that incorporates Mäori language and/or knowledge, rather than Mäori participation in science education).

Science,Society and Trends in Science Education‐‐some Thoughts on the Development of Integrated Science in the Educational Systems of the World

Summaries

English

Before constructing a new curriculum for any level in integrated‐science education, it is very important to establish a basic philosophy of science teaching which reflects a symbiotic relationship between education and the socio‐economic development in a particular country of the world.

The curriculum structure of integrated‐science education should broaden the basis of curricular decision and should be designated to follow the expectations of the society in providing professional intellectual training so that education can make a significant contribution to the socio‐economic growth of the country. This basic assumption which established a link between cultural and socio‐economic growth, involves a diversification of the cultural trends of science education which must become appropriate to the economic and historical context of each country in a fast changing world of work.

Therefore, by critically removing outside influences in the transmission of scientific knowledge, there should be less uniformity in the context and methods of teaching, and considerable restructuring of education for each country should occur. Thus, considering the historical and geographical differences, a new order in international division of labour would come into being.

In such a hypothesis, a research‐oriented integrated curriculum in science education can play a central role (certainly a better one than in the traditional, discipline‐oriented scheme of science teaching) in obtaining an adequate interaction between scientific education and social problems; this is required for modern cultural and economic development of the world.     

Science Teachers’ Professional Development and Changes in Science Practical Assessment Practices: What are the Issues?

This paper considers the circumstances under which science teachers can respond positively and productively to educational policy reforms in the area of science practical assessment. To understand what might be involved in linking science teachers’ assessment capacities and their professional development, we present illustrative data from recent research studies conducted in Singapore and Hong Kong showing contrasting approaches taken in the implementation of reforms in science practical assessment. In Singapore, teachers worked together to select, discuss, clarify and refine their practices as they made decisions about what to teach and assess. In Hong Kong, teachers took a critical stance towards the new policy and learnt from their own experiences in order to build their confidence. With the same policy initiative, one group of teachers focused more on the technicalities of complying with requirements imposed on them while in the other group had their professional consciousness of what they thought was best for their students provoked so that their practices would be transformed. In an attempt to draw lessons for other contexts in supporting the implementation of assessment policy reforms through professional development work, we identify and discuss a range of factors in science teachers’ professional development that arise once in situ professional development work has started. Overall, our intent in this article is to recast assessment reform as a driver or pivot in teachers’ professional development and learning. To do this it is necessary, we argue, to afford teachers’ experiences and the processes involved in learning from them greater emphasis in order to ensure the continuance of innovation in the assessment of laboratory-based work.     

Modelling the Sociocultural Contexts of Science Education: The Teachers’ Perspective

A growing body of research argues that teachers’ beliefs and practices should be studied within the sociocultural contexts of their work because the relationship between their beliefs and practices is both complex and context-dependent. There is a need for further research in this area in understudied contexts such as developing countries, in order to promote effective education in schools and the professional development of teachers. This paper argues that if this ‘black box’ of sociocultural contexts in which science teachers are embedded is better understood, it may be possible to identify specific aspects of these contexts related to educational organizations that act as either supports or barriers to pedagogical reform or to implementing innovations in science education. Consequently, the main purpose of this study is to explore the sociocultural contexts of ten Egyptian science teachers and to what extent these sociocultural contexts help in understanding teachers’ pedagogical beliefs and practices. This paper, by utilizing a multi-grounded theory approach and qualitative methods, reveals a variety of sociocultural contexts that are related to teachers’ pedagogical beliefs and practices.
