Gender-inclusive science teaching: A feminist-constructivist approach

The underrepresentation of women in science is an extensively studied yet persistent concern of our society. Researchers have identified numerous educational and social factors thought to be responsible for this underrepresentation (Kahle, 1990a; Kelly, 1987). One of the dominant explanations, used by many researchers for years to discuss gender differences in science and mathematics achievement as well as interest, has been the differences in the cognitive abilities of men and women. This explanation, however, has been discarded in recent years (Linn & Hyde, 1989; Linn 1990). On the basis of their meta-analyses of various studies. Linn and Hyde (1989) concluded that gender differences in cognitive skills have declined and those that remain are largely explained by experiential differences. Women may not have different cognitive abilities, but they may have a different way of learning rooted in their role in society. The epistemic differences between men and women stemming from their standpoint in life can help us understand their differential interaction with the nature of science, and hence their participation in the field. In the following section, we will briefly discuss the feminist critique of science and extend the implication to science education.     

A constructivist approach to change in elementary science teaching and learning

Constructivism is a set of beliefs that can be used by teachers to think about learning and teaching and to plan and enact a science curriculum. This paper is a fictional account of an elementary science teacher and her use of constructivism as a referent for her various roles as a science teacher. The paper also describes how the teacher came to teach in this manner, describing her involvement in staff development activities and an evolution in her thinking from an ojectivist to a constructivist system of semantics. Implications are presented for the reform of science education.     

An aesthetic approach to the teaching of science

The role of aesthetic curiosity in the manipulation of materials is often ignored or considered irrelevant in most science curricula. Contemporary practice in curriculum design emphasizes an approach that views science and art as separate types of explorations. Some historians of technology and science suggest that basic discoveries arise out of an aesthetic curiosity fostered by play with materials or ideas. Experience with certain familiar materials of aesthetic interest suggest that children will sustain play for long periods and easily mix metaphors of art and science in developing an understanding of the phenomena that are a part of the experience. Several examples are given of how this might be accomplished.     

An inquiry approach to science and language teaching

The purpose of this study was to determine the effectiveness of an inquiry approach to science and language teaching to further develop classification and oral communication skills of bilingual Mexican American third graders. A random sample consisting of 64 subjects was selected for experimental and control groups from a population of 120 bilingual Mexican American third graders. The Solomon Four-Group experimental design was employed. Pre- and posttesting was performed by use of the Goldstein-Sheerer Object Sorting Test, (GSOST) and the Test of Oral Communication Skills, (TOCS). The experimental group participated in a sequential series of science lessons which required manipulation of objects, exploration, peer interaction, and teacher-pupil interaction. The children made observations and comparisons of familiar objects and then grouped them on the basis of perceived and inferred attributes. Children worked individually and in small groups. Analysis of variance procedures was used on the posttest scores to determine if there was a significant improvement in classification and oral communication skills in the experimental group. The results on the posttest scores indicated a significant improvement at the 0.01 level for the experimental group in both classification and oral communication skills. It was concluded that participation in the science inquiry lessons facilitated the development of classification and oral communication skills of bilingual children.     

Effective teaching approach employed by primary school science teachers

Teachers are often urged to use a variety of modes of instruction to ensure that diverse student interests and abilities can be accomodated. Yet teachers can be limited in the instructional modes they can use because of insufficient background or knowledge about a specific instructional mode （Dawson, 2004）. Teaching approaches are various in purposes such as to trigger students＇ interest in science, to discover through inquiry approach, to build students understanding through constructivism approach or to introduce a concept through demontration approach. Every approach has the strength and weakness in its use. Although inquiry may not be the only way to teach science, many science educators believe that it may be the best way for students to learn science （Audet ＆ Jordan, 2005）. According to Woolfolk （2001）, constructivism is a mode of instruction that emphasizes the active role of the learner in building, understanding and making sense of information. Demonstrations by teacher can be used with students of all ages and across all subjects. The teacher is not only knowledgeable about the topic but also uses a variety of aids to ensure that students understand what is being demonstrated （Marsh, 2004）. By studying their teaching approaches and methods, the actual practices could be analysed and the effectiveness status of their effectiveness could be determined. Specifically, this study aimed to answer these questions in terms of three approaches namely inquiry, constructivism and demonstrations; how far is this approach effective in terms of teaching and learning, and what is the correlation between these three approaches. Data were collected from primary school science teachers （N=239） and the results shown that the teachers were agreeable with the three approaches, inquiry approach （mean=3.74, SD=0.27）, demonstration approach （mean=3.61, SD=0.27） and constructivism approach （mean=3.86, SD=0.30）. The results also showed that there are significant correlations among inquiry, demonstration and constructivism approach. This finding showed that primary school science teachers not depend only on one type of approach and apply variously in teaching science. There are also positive and significant correlation between that approaches used by primary school science teachers.     

A typology of approaches to science teaching in schools

Bentley and Watts (1986) have recently argued that fundamental changes in science are necessary if girls’ needs and expectations in school science are to be met. They explore the implications of a radical shift, from a masculine to a feminist view of science, in terms of the context and conduct of school science, and warrant their attempt to reconstruct a feminist science largely by reference to ‘new paradigm’ research in the social sciences. By exploring the reasons underlying the adoption of ‘new paradigm’ methods in the social sciences, I argue that their explication of a feminist science lacks an important feature that would hinder its consideration as an alternative vision of scientific inquiry and as a basis for changing the content of science curriculum in schools. I further question their need to look to the social sciences as a model, when many social scientists have turned to the physical sciences for inspiration in attempting to reconstruct their own disciplines. By exploring the tenets most commonly held in present‐day science and examining the nature of scientific understanding, I argue that their view of ‘normal’ science is a highly simplified and incomplete stereotype of scientific inquiry. It is suggested that the nature of science is not the root problem, as Bentley and Watts would have us believe.     

影响科学认识的因素研究

社会需求是促进科学认识发展的首要因素，社会历史文化及宗教对科学认识具有促进和制约双重作用。人类认识能力是科学认识的基础，科学自身发展水平和科学认识手段限制着科学认识，学科分化对科学认识具有制约作用，非意识后果对科学认识提出了新的挑战。弄清楚这些问题能为人类解决科学发展中面临的困境寻求一条出路。     

Teaching science as a language: A “content‐first” approach to science teaching

Our research project was guided by the assumption that students who learn to understand phenomena in everyday terms prior to being taught scientific language will develop improved understanding of new concepts. We used web‐based software to teach students using a “content‐first” approach that allowed students to transition from everyday understanding of phenomena to the use of scientific language. This study involved 49 minority students who were randomly assigned into two groups for analysis: a treatment group (taught with everyday language prior to using scientific language) and a control group (taught with scientific language). Using a pre–post‐test control group design, we assessed students' conceptual and linguistic understanding of photosynthesis. The results of this study indicated that students taught with the “content‐first” approach developed significantly improved understanding when compared to students taught in traditional ways. © 2008 Wiley Periodicals, Inc.

A constructivist approach to secondary school science experiments

The focus of this study was on the investigation of a laboratory instructional program on electricity designed for conceptual development using constructivist principles for conceptual change. This approach was compared with a traditional laboratory approach in a quasi-experimental design. The sample was 247 grade 10 students (boys) in a large non-government urban school. Covariance analysis with the corresponding pretest as covariate showed statistically and educationally significant gains for the experimental group on cognitive but not attitudinal outcomes when compared to the traditional group. Student and teacher interview data provide some evidence for the success of the experimental approach. Specializations: physics education, constructivist approaches to in practical work. Specializations: science teacher education, learning environments, conceptual change.     

Connecting university science experiences to middle school science teaching

Summary Science teachers naturally rely on their university science experiences as a foundation for teaching middle school science. This foundation consists of knowledge far too complex for the middle level students to comprehend. In order for middle school science teachers to utilize their university science training they must search for ways to adapt their college experiences into appropriate middle school learning experience. The criteria set forth above provide broad-based guidelines for translating university science laboratory experiences into middle school activities. These guidelines are used by preservice teachers in our project as they identify, test, and organize a resource file of hands-on inquiry activities for use in their first year classrooms. It is anticipated that this file will provide a basis for future curriculum development as the teacher becomes more comfortable and more experienced in teaching hands-on science. The presentation of these guidelines is not meant to preclude any other criteria or considerations which a teacher or science department deems important. This is merely one example of how teachers may proceed to utilize their advanced science training as a basis for teaching middle school science.     

Problem-based (group) teaching: a cognitive science approach to using available knowledge

An important objective in education generally, and tertiary education in particular, is the imparting of the ability to use acquired knowledge when solving problems. Both within tertiary education itself and in society, however, the complaint is frequently heard that it is precisely in this respect that the training of students is deficient.An alternative to conventional methods of teaching how to apply knowledge is to use explicitly problem-based teaching. Using a theoretical perspective derived from both an action-oriented and an information-processing perspective, it is shown that the problem-based approach has more potential. Maximizing this potential requires cognizance of the various types of problem-based approach, whose variants depend on the problem, the extent of pre-structuring and the roles assigned to individuals in a group. Also important is the systemic position of problem-based teaching in a curriculum.
