Technology in the curriculum: A vehicle for the development of children's understanding of science concepts through problem solving

This research was carried out over a period of ten months with children in Grades 2 and 3 (aged 7 and 8) who were participating in a sequence of technology activities. Since the introduction into Victorian primary schools ofThe Technology Studies Framework P-10 (Crawford, 1988), more teachers are including technology studies in their classrooms and by so doing may assist children's understanding of science concepts. Children are being exposed to science phenomena related to the technology activities and Technology Studies may be a way of providing children with science experiences. ‘Technology Studies’ in this context refers to children carrying out practical problem solving tasks which can be completed without any particular scientific knowledge. Participation in the technology activities may encourage children to become actively involved, thereby facilitating an exploration of the related science concepts. The project identified the importance of challenge in relation to the children's involvement in the technology activities and the conference paper (available from the first author) discusses particular topics in terms of the balance between cognitive/metacognitive and affective influences (Baird et al., 1990) Specializations: science and technology education, interest and attitudinal change. Specialization: technology in the primary school.     

Learning in interactive science centres

The potential of informal sources of science learning to supplement and interact with formal classroom science is receiving increasing recognition and attention in the research literature. In this study, a phenomenographic approach was used to determine changes in levels of understanding of 27 grade 7 primary school children as a result of a visit to an interactive science centre. The results showed that most students did change their levels of understanding of aspects of the concept “sound”. The study also provides information which will be of assistance to teachers on the levels of understanding displayed by students on this concept.

Response to the discipline review of teacher education in mathematics and science

This paper relates to a study commissioned by the Department of Employment, Education and Training to evaluate the impact of the Discipline Review of Teacher Education in Mathematics and Science. The major datagathering strategies employed in that study have been to visit every higher education institution in Australia involved in teacher education to interview relevant staff and to seek information by mail from other bodies to whom recommendations of the Review were addressed. This paper reports a supplementary activity, the analysis of citations of the Report of the Discipline Review in the journal of the Australasian Science Education Research Association,Research in Science Education. This research reveals that there has been relatively little critical analysis of the Review, somewhat surprising in the light of its significance for science teacher education. Further the citations in the journal suggest that the Review Report has struck a responsive chord with those involved in the science education of primary school teachers. Its impact on secondary teacher education would appear to be less significant. This difference is explored in the context of professional education.

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.

How can we find out what 3 and 4 year olds think? New approaches to eliciting very young children's understandings in science

This paper outlines work in progress on a study which is investigating what children understand about natural and processed materials and how scientific learning on the topic could be extended and reinforced in the home. Four different interview schedules for eliciting children's understanding were developed and tried out. Children's understandings prior to each of the four units, and at the conclusion of the teaching program were documented through individual interviews. Family interviews were also conducted prior to and at the conclusion to the teaching. In this paper the difficulties associated with researching young children's thinking are explored. The rationale for a storytelling context for the interviews is presented, and there is a preliminary discussion on the effectiveness of the methodology utilised.

A research method using microcomputers to assess conceptual understanding and problem solving

Important goals in science education include the elucidation of how students develop a world view, reason about new information, and solve problems. This paper focuses on a research strategy using microcomputers that is directed towards elucidating conceptual understanding and problem solving strategies used by subjects interacting with an open-ended genetics simulation. The field method employed in this study is termed “structured observations”. The use of this method facilitated the generation of data during problem solving sessions by subjects in a think aloud protocol. Three sets of synchronized information of subjects’ interactions with the software were obtained: a video image which provided the sequence and duration of computer screen displays, a video image of subjects, and an audio track of verbal commentaries. The verbal protocol data, complemented by synchronized visual data, were analyzed using software tools for qualitative analysis. The use of these kinds of software programs aided researchers in the analysis of complex, qualitative data. The data were subjected to codings as text files, searches for patterns, and retrievals of patterns among coded variables. Frequency tables of the codes and patterns were generated for further interpretation. By these means, patterns of operations can be identified and inferences made about problem solvers’ conceptual understanding.

The role of language in science education: Some reflections from Fiji

One of the issues identified in a recent study of science teaching and learning in Fiji's primary and secondary schools was the problems faced by students in coping with scientific terminology, and in expressing ideas in their own words (Muralidhar, 1989). In this paper, some examples from the study are used to illustrate the extent of the problem and to discuss the implications for teaching and learning science. It is argued that the quality of communication is an important factor in promoting the understanding of science, especially when the main sources of information for the majority of students are the textbook and the teacher.

Determinants of the competence and confidence of teacher education students studying primary science education

Conclusion This study suggests that most students entering science or science education units in preservice primary teacher education courses have a positive attitude to the teaching/learning of primary science and see value in all domains of science for children at this stage. This was an unexpected finding. It was of concern however, that their interest in physical science topics was so low. This may be due to previous specific experiences in secondary science. Science and science education units should build on the positive attitudes of students and could develop physical science ideas through their significance in environmental and social problems.

Progression in learning science

A national curriculum comprising statements of attainment at different levels must be underpinned by some idea of “progression” in learning. Questions arise as to the nature and meaning of progression. To gain a deeper insight into how children progress in their understanding of science, this research involves the construction and testing of a hypothetical learning sequence for the topic of forces. This interim report explains how children aged 7 to 13 are being interviewed to explore their explanations of phenomena involving forces. These explanations will be mapped onto the sequence to provide a multi-dimensional model of progression. Specializations: assessment, curriculum development.

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.

Changing primary teacher trainees' attitudes to science

A study of primary teacher trainees' perceptions and attitudes to science in 1990, has been useful in designing a semester unit aimed at increasing the confidence and interest of first year students at Victoria College. This paper outlines the background survey and discusses some, of the results and how they were used to develop the Professional Readiness Study-Understanding Science. This unit attempts to change attitudes by focussing on metacognition and encourages students to understand and control their own learning. Discussion involves teaching and learning strategies and alternative assessment approaches including the student's journal-the Personal Record.

An outline of the development in science has been presented here to:invite comment from science educators in order to help define future directions in curriculum development; tostimulate further research in the area of curriculum development for a ‘Science for All’, and tostimulate debate about what school science, especially junior secondary science, should be.     

The development of a K-3 science program in the context of the National Science Statement and Profile

This paper highlights the challenges and problems in developing an innovative K-3 science program to support teachers in the implementation of the national Statement and Profile in science. The program has been developed by the authors in association with the Curriculum Corporation. The paper outlines the assumptions made about teachers of young children, the role of research in the construction of the program, and the extent to which the Statement and Profile have influenced the process. The resolution of a number of key problems in this curriculum development is discussed: responding to teachers' needs for a base of science discipline knowledge, developing strategies for working scientifically with very young children, and helping teachers develop an extended understanding of the nature of science. Specializations: early childhood science and technology education. Specializations: primary science education, teacher education in science, adult experiences of science and technology, and curriculum development.     

Responses to an interactive science exhibit in a school setting

Unattended science and technology exhibits of both static and operational types have been an integral part of museum displays for many years. More recently interactive exhibits in which observers are encouraged to become part of the system of exhibits have become more common. A study was commenced to explore the impact and potential of low cost, unattended, interactive exhibitsset up singly in a normal school classroom without the distractions of a multiplicity of activities as is common in ‘science museums’. Three small groups of Grade 5/6 primary school children interacted with a ‘Falling Towers’ exhibit and their voluntary activities were recorded on videotape for later analysis. Children appeared to state the results of their activity in ways consistent with their expectations rather than with their most recent experience with the exhibit. The responses of girls, boys and mixed groups are reported. Specializations: primary mathematics and science education, teaching strategies.

Teacher beliefs about learning and teaching in primary science and technology

It is argued that the introduction of many new curricular with their associated teaching practices have failed because the beliefs, views and attitudes of teachers have been ignored. This paper reports the implications of the initial belicfs of primary school teachers involved in a professional development program about science and technology education. In particular, a mismatch between teachers views of learning and teaching is identified and analysed.

Teacher professional development: Which aspects of inservice do teachers believe influence their classroom practice?

Research into teacher inservice in primary science generally focuses on evaluating the objectives of each program in terms of the immediate outcomes. Little research appears to have been conducted into the long term effects of interactive inservice programs on the classroom practice of the participants. During 1993 the long term effects of participation in the Primary Science/Technology Project (Sci-Tec), as perceived by the teacher participants, were investigated. Focus teachers who had participated in Sci-Tec between 1988–1991 were asked to provide information about their current science teaching practice, and about the influence that Sci-Tec had had on their current practice. Six of these teachers were then interviewed to determine which specific aspects of the project they believed had most influenced the development of their current classroom practice in teaching science. Specializations: inservice and preservice in primary science and technology.     

Measuring Graph Comprehension,Critique, and Construction in Science

Interpreting and creating graphs plays a critical role in scientific practice. The K-12 Next Generation Science Standards call for students to use graphs for scientific modeling, reasoning, and communication. To measure progress on this dimension, we need valid and reliable measures of graph understanding in science. In this research, we designed items to measure graph comprehension, critique, and construction and developed scoring rubrics based on the knowledge integration (KI) framework. We administered the items to over 460 middle school students. We found that the items formed a coherent scale and had good reliability using both item response theory and classical test theory. The KI scoring rubric showed that most students had difficulty linking graphs features to science concepts, especially when asked to critique or construct graphs. In addition, students with limited access to computers as well as those who speak a language other than English at home have less integrated understanding than others. These findings point to the need to increase the integration of graphing into science instruction. The results suggest directions for further research leading to comprehensive assessments of graph understanding.     

Preschool children's interests in science

Studies of children's attitudes towards science indicate that a tendency for girls and boys to have different patterns of interest in science is established by upper primary school level. It is not know when these interest patterns develop. This paper presents the results of part of a project designed to investigate preschool children's interests in science. Individual 4–5 year-old children were asked to say what they would prefer to do from each of a series of paired drawings showing either a science and a non-science activity, or activities from two different areas of science. Girls and boys were very similar in their overall patterns of choice for science and non-science items. Within science, the average number of physical science items chosen by boys was significantly greater than the average number chosen by girls (p=.026). Girls tended to choose more biology items than did boys, but this difference was not quite significant at the .05 level (p=.054). The temporal stability of these choices was explored.

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.
