The Spectrum of Dynamic Inquiry Teaching Practices

The Israeli high school biology curriculum comprises the Biomind program, in which students are engaged in an open inquiry learning process. The dynamic features of open inquiry often pose challenges to teachers in implementing the Biomind program. The current qualitative research shows that facilitating students in a dynamic open inquiry process is multidimensional. Teaching practices cover a wide range of methods, from structured inquiry through guided inquiry to open inquiry. An individual teacher’s profile can be elucidated on the basis of this spectrum. In addition, we realised that teachers often encounter several difficulties in implementing open dynamic inquiry: A dearth of teachers’ scientific knowledge, students’ lack of scientific knowledge and skills, and a restrictive time-frame. This study suggests several areas which should be considered while implementing an on going professional development support for teachers who are engaged in open inquiry teaching.     

Year 12 students’ attainment of scientific investigation skills

One of the main goals of science education is the development of scientific investigation skills (Bryce & Robertson, 1985; Woolnough & Allsop, 1985). This paper describes a practical test instrument developed to assess students’ attainment of skills associated with problem analysis and planning experiments, collecting information, organizing and interpreting information, and concluding. During administration of the test, students verbalized their thoughts as they worked on the task and their performance was videotaped for analysis. Preliminary results reveal important areas of student weakness and lead to recommendations for curriculum reform.

Outcomes of the primary and early childhood science and technology education project at the university of Canberra

The aim of the Primary and Early Childhood Science and Technology Education Project (PECSTEP) is to improve teaching and learning in science and technology of by increasing the number of early childhood and primary teachers who are effective educators. PECSTEP is based on an interactive model of teaching and systematically links work on gender with the learning and teaching of science and technology. The project involves: a year-long inservice program which includes the development of a science curriculum unit by teachers in their schools; linking of the preservice and inservice programs; and the development of support networks for teachers. Each phase of PECSTEP has been researched by means of surveys, interviews and the use of diaries. Research questions have focussed particularly on changes in: teachers’ and student teachers’ attitudes to teaching science and technology; their perceptions of science and technology; their perceptions of their students’ responses and their understandings of how gender relates to these areas. Specializations: primary science curriculum, science teacher education, sociology of science, technology and education. Specializations: gender and science/science teacher education, feminist theory, curriculum theory. Specializations: Science education research, curriculum development.     

The influence of gender,ethnicity and rurality upon perceptions of science

This paper reports an investigation into gender, ethnicity and rurality on Fijian students’ perceptions of science. A questionnaire was administered to a large sample of Form 5 classes. All students had completed a four year integrated "Basic Science" course in the junior secondary school and were continuing their studies in the upper secondary school. The responses were analysed to determine the significance of gender, ethnicity and rurality on the students’ perceptions of science, attitudes to science in the world and to science in the school curriculum. Specializations: gender issues and affective aspects of science and technology education. Specializations: Constructivism in science education, development education and gender issues.     

The constructivist paradox: Teachers’ knowledge and constructivist science teaching

Advocates of constructivist science recommend that school science begins with children’s own constructions of reality. This notion of the way in which students’ knowledge of science grows is closely paralleled by recent research on teachers’ knowledge. This paper draws on case study evidence of teachers’ work to show how two experienced teachers’ attempts to develop alternative ways of teaching science involved reframing their previous patterns of understanding and practice. Two alternative interpretations of the case study evidence are offered. One interpretation, which focuses on identifying gaps in the teachers’ knowledge of science teaching, leads to theconstructivist paradox. The second interpretation explores theconstructivist parallel, an approach which treats the process of teachers’ knowledge growth with the same respect as constructivists treat students’ learning of science. This approach, the authors argue, is not only more epistemologically consistent but also opens up the possibilities of helping teachers lead students towards a constructivist school science. Specializations: Teachers’ knowledge and culture, educational change, qualitative research methodology. Specializations: Teachers’ knowledge, imagery and teachers’ work, teacher collegiality, supervision of teachers’ work.     

Students’ Learning Processes during School-Based Learning and Workplace Learning in Vocational Education: A Review

Learning in vocational schools and workplaces are the two main components of vocational education. Students have to develop professional competences by building meaningful relations between knowledge, skills and attitudes. There are, however, some major concerns about the combination of learning in these two learning environments, since vocational schools are primarily based on the rationales of learning and theory, while workplaces are based on the rationales of working and practice. This study therefore aims to structure empirical insights into students’ learning processes during the combination of school-based learning and workplace learning in vocational education. A review-study has been conducted in which ultimately 24 articles were analyzed thoroughly. The review shows that students’ learning processes in vocational schools and workplaces are related to six main themes: students’ expertise development, students’ learning styles, students’ integration of knowledge acquired in school and workplace, processes of knowledge development, students’ motivations for learning and students’ professional identity development. Our results show that students are novices who use specific and different learning styles and learning activities in vocational schools and workplaces. It is concluded that the enhancement of students’ learning processes needs to be adaptive and differentiated in nature. Recommendations for further research are elaborated and suggestions for the enhancement of students’ learning processes are discussed using insights from hybrid learning environments and boundary crossing via boundary objects.     

The Significance of Practical Training in Linking Theoretical Studies with Practice

Today’s experts must continuously reconstruct their expertise and be able to apply their theoretical knowledge in actual work. The development of expertise is a long process, during which theoretical, practical and metacognitive elements of expert knowledge are integrated into a coherent whole. It is important to foster student’s learning and integration of theoretical knowledge in practice during tertiary education. One tool for this is to pay more attention to practical knowledge in the theoretical part of the curriculum. The aim of this study was to evaluate the significance of early practical training as a part of the pharmacy curriculum and to find out to what extent the students felt their practical training fostered their learning. A total of 47 pharmacy students were interviewed during the three-month practice period. Content analyses of the interviews showed that the practical training increased students’ understanding of theoretical knowledge and their motivation to study. The students acquired practical skills and knowledge in a working community of professionals. The results also showed that the students should be able to rehearse their reflective skills during the theoretical studies as well, because the practice period was too short to permit adequate development of reflective skills.     

Question Posing, Inquiry, and Modeling Skills of Chemistry Students in the Case-Based Computerized Laboratory Environment

A new learning unit in chemistry, Case-based Computerized Laboratories (CCL) and Computerized Molecular Modeling (CMM) was developed at the Technion. The CCL and CMM curriculum integrates computerized desktop experiments and molecular modeling with an emphasis on scientific inquiry and case studies. Our research aimed at investigating the effect of the CCL and CMM learning environment on students’ higher-order thinking skills of question posing, inquiry, and modeling. The experimental group included 614 honors 12th grade chemistry students from high schools in Israel who studied according to this learning unit. The comparison group consisted of 155 12th grade chemistry honors students who studied other chemistry programs. Pre- and post-tests questionnaires were used to assess students’ higher-order thinking skills. Students’ responses were analyzed using content analysis rubrics and their statistical analysis. Our findings indicated that the scores of the experimental group students improved significantly in question posing, inquiry and modeling skills from the pre-test to the post-test. The net gain scores of the experimental group students were significantly higher than those of their comparison peers in all three examined skills. In modeling skills, experimental group students significantly improved their achievements in making the transfer from 3D models to structural formulae, but only about half of them were able to transfer from formulae to 3D models. By presenting a case-based chemistry assessment tool and content analysis of students’ responses in this paper, we enable teachers and educators to analyze their students’ higher-order thinking skills both qualitatively and quantitatively.     

The Role of Computer Simulation in an Inquiry-Based Learning Environment: Reconstructing Geological Events as Geologists

Several researchers have investigated the effects of computer simulations on students’ learning. However, few have focused on how simulations with authentic contexts influences students’ inquiry skills. Therefore, for the purposes of this study, we developed a computer simulation (FossilSim) embedded in an authentic inquiry lesson. FossilSim integrated data from real field investigations with geological laws for identifying the sequence of geological events. Data were collected from two experiments to examine ninth graders’ abilities for reconstructing a sequence of geological events with the aid of FossilSim. The sample groups in Experiments 1 and 2 were 58 and 11 ninth graders, respectively. The results indicated that the authentic inquiry lesson promoted the development of students’ inquiry skills. In addition, FossilSim played a key role in engaging students to apply geological laws, make multi-scale observations, and clarify their ideas about geological time.     

Exploring the potential impact of reciprocal peer tutoring on higher education students’ metacognitive knowledge and regulation

It is widely recognized that metacognition is an important mediator for successful and high-level learning, especially in higher education. Nevertheless, a majority of higher education students possess insufficient metacognitive knowledge and regulation skills to self-regulate their learning adequately. This study explores the potential of reciprocal peer tutoring to promote both university students’ metacognitive knowledge and their metacognitive regulation skills. The study was conducted in a naturalistic higher education setting, involving 67 students tutoring each other during a complete semester. A multi-method pretest–posttest design was used combining a self-report questionnaire, assessing students’ metacognitive knowledge and their perceived metacognitive skilfulness, with the analysis of think-aloud protocols, revealing students’ actual use of metacognitive strategies. Results indicate no significant pretest to posttest differences in students’ metacognitive knowledge, nor in their perception of metacognitive skill use. In contrast, significant changes are observed in students’ actual metacognitive regulation. At posttest, students demonstrate significantly more frequent and more varied use of metacognitive regulation, especially during the orientation, monitoring, and evaluation phases. Furthermore, our findings point to an increase in more profound and higher-quality strategy use at posttest.     

Learning-based curriculum development

This article is written to inspire curriculum developers to centre their efforts on the learning processes of students. It presents a learning-based paradigm for higher education and demonstrates the close relationship between curriculum development and students’ learning processes. The article has three sections: Section “The role of higher education (HE) institutions” presents a discussion of the role of higher education in the knowledge society. Section “Contextual learning” presents the paradigm of contextual learning which we see as a useful foundation for curriculum development. Section “Curriculum development in practice—the BETA course” shows how a particular course in Business Economic Theory and Analysis has been developed using this paradigm. The article will be of interest to all academics interested in students’ learning processes but is especially relevant to those responsible for curriculum development.     

Developing a taxonomy of science concepts based on a scale of empirical distance

The term ‘concept’ is used in different ways within educational literature and has at least two different, although related, referents in relation to science knowledge, namely, public knowledge and private understandings. A taxonomic structure for ‘science concepts’ (public knowledge) has been developed to provide a rationale for the choice of phenomena to be used in the investigation of students’ ‘concepts’ and also to act as a frame of reference for generating insights about the data to be collected. Furthermore, it may be a useful heuristic to predict other science concepts likely to be highly problematic in school teaching situations and thus worthy of detailed research. The taxonomy, called a ‘Scale of Empirical Distance’ (SED), enables science concepts to be mapped according to their degree of closeness to concrete realities. The scale shows a recognition of the empirical basis of science concepts and the role of human senses in the perception of the material world even though “absolute objectivity of observation is not a possible ideal of science” as Harre (1972) has noted. The scale uses two binary variables, namely, ‘visual’ and ‘tactile’, to generate four categories of science concepts ranging on a continuum from concrete to abstract. Some concepts related to ‘matter’ will be classified and discussed. Specializations: science teacher education, primary science curriculum and methods, students’ personal meanings of phenomena.     

Australian studies: A vehicle for scientific and technological literacy?

In Victoria, schools are adopting one common certificate, the VCE (Victorian Certificate of Education) which encompasses two years of study (Years 11 and 12) and comprises 44 subject areas or Studies, each of one semester duration. Amongst the compulsory subjects is Australian Studies (Units 1 and 2) with its focus on Work in Australian society. This paper discusses concerns about the teaching of the compulsory subject Australian Studies in the new VCE. The purpose is to consider whether the science and technology component in the Australian Studies course can raise the students’ level of scientific and technological literacy. The discussion is based on one semester’s teaching experience of Year 11 Australian Studies and consequent reflections on practice. Specializations: science and technology teacher education, technology in the curriculum.     

Understanding The Impact of an Apprenticeship-Based Scientific Research Program on High School Students’ Understanding of Scientific Inquiry

The purpose of this study was to understand the impact of an apprenticeship program on high school students’ understanding of the nature of scientific inquiry. Data related to seventeen students’ understanding of science and scientific inquiry were collected through open-ended questionnaires. Findings suggest that although engagement in authentic scientific research helped the participants to develop competency in experimentation methods it had limited impact on participants’ learning of the implicit aspects of scientific inquiry and NOS. Discussion focuses on the importance of making the implicit assumptions of science explicit to the students in such authentic scientific inquiry settings through structured curriculum.     

Gender-inclusive technology materials for the primary school: A case study in curriculum development

This paper describes how an idea for technology education materials developed into a process for producing unique curriculum modules for teaching technology in a gender-inclusive way to primary children. Using a case-study format, the paper describes the interaction between participants, the sequential evolution of the materials themselves and the degree to which success was achieved in terms of the original goals. The study demonstrates how an awareness of gender bias needs to be a feature from the earliest stages of curriculum development, through to the trialling and modification stages. The curriculum materials were a product of effective cooperation between teachers, science educators and community representatives. They utilise a “process” approach to the teaching of technology and in this presentation, we demonstrate how this same approach is a useful framework for describing this particular curriculum development. Specializations: primary science and technology education, gender issues. Specializations: diagnosis of student learning and teaching for conceptual change, technology education, curriculum evaluation. Specializations: affective aspects of science and technology education, gender issues.     

Gender inclusive Curricula: A focus on two responses

One of the requirements of the New Zealand Curriculum Framework (Ministry of Education, 1993a) is that all curricula developed in New Zealand must be gender inclusive. Developers of the recently released science curriculum, and the draft technology curriculum, have responded to this requirement in different ways. In this paper I discuss a theorisation of the term ‘gender inclusive’ within national curriculum development generally, and explore and analyse these different responses within the specific context of the science and technology curriculum developments. Particular emphasis is placed on the historical difference between science education and technology education in New Zealand schools, and on the impact theoretical discourses have on the way in which terms such as ‘gender inclusive curricula’ are conceptualised, and viewed as appropriate, or not, for specific purposes. Specializations: feminist theory, science education, technology education, technology curriculum development.     

Perceptual Influence of Ugandan Biology Students’ Understanding of HIV/AIDS

In Uganda, curbing the spread of HIV/AIDS has largely depended on public and private media messages about the disease. Media campaigns based on Uganda’s cultural norms of communication are metaphorical, analogical and simile-like. The topic of HIV/AIDS has been introduced into the Senior Three (Grade 11) biology curriculum in Uganda. To what extent do students’ pre-conceptions of the disease, based on these media messages influence students’ development of conceptual understanding of the disease, its transmission and prevention? Of significant importance is the impact the conceptions students have developed from the indirect media messages on classroom instruction on HIV/AIDS. The study is based in a theoretical framework of conceptual change in science learning. An interpretive case study to determine the impact of Ugandan students’ conceptions or perceptions on classroom instruction about HIV/AIDS, involving 160 students aged 15–17, was conducted in four different Ugandan high schools: girls boarding, boys boarding, mixed boarding, and mixed day. Using questionnaires, focus group discussions, recorded biology lessons and informal interviews, students’ preconceptions of HIV/AIDS and how these impact lessons on HIV/AIDS were discerned. These preconceptions fall into four main categories: religious, political, conspiracy and traditional African worldviews. Results of data analysis suggest that students’ prior knowledge is persistent even after biology instructions. This has implications for current teaching approaches, which are mostly teacher-centred in Ugandan schools. A rethinking of the curriculum with the intent of offering science education programs that promote understanding of the science of HIV/AIDS as opposed to what is happening now—insensitivity to misconceptions about the disease—is needed.     

Using the SEE-SEP Model to Analyze Upper Secondary Students’ Use of Supporting Reasons in Arguing Socioscientific Issues

To achieve the goal of scientific literacy, the skills of argumentation have been emphasized in science education during the past decades. But the extent to which students can apply scientific knowledge to their argumentation is still unclear. The purpose of this study was to analyse 80 Swedish upper secondary students’ informal argumentation on four socioscientific issues (SSIs) to explore students’ use of supporting reasons and to what extent students used scientific knowledge in their arguments. Eighty upper secondary students were asked to express their opinions on one SSI topic they chose through written reports. The four SSIs in this study include global warming, genetically modified organisms (GMO), nuclear power, and consumption. To analyse students’ supporting reasons from a holistic view, we used the SEE-SEP model, which links the six subject areas of sociology/culture (So), environment (En), economy (Ec), science (Sc), ethics/morality (Et) and policy (Po) connecting with three aspects, knowledge, value and personal experience (KVP). The results showed that students used value to a greater extent (67%) than they did scientific knowledge (27%) for all four SSI topics. According to the SEE-SEP model, the distribution of supporting reasons generated by students differed among the SSI topics. Also, some alternative concepts were disclosed in students’ arguments. The implications for research and education are discussed.
