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.

Research into the environment of science laboratory classes in australian schools

Existing instruments for assessing student or teacher perceptions of characteristics of actual or preferred classroom psychosocial environment are unsuitable for one of the most important settings in science teaching, namely, the science laboratory class. Consequently, the Science Laboratory Environment Inventory (SLEI), was designed to assess student or teacher perceptions of seven scales:Teacher Supportiveness, Student Cohesiveness, Open-Endedness, Integration, Organization, Rule Clarity andMaterial Environment. An important feature of the design of the study was that the new instrument was field tested simultaneously in six countries: Australia, USA, Canada, England, Nigeria and Israel. This paper is based on a sample of 4643 students in 225 individual laboratory classes, together with the teachers of most of these classes. Preliminary analyses were used to shed light on various important research questions including the differences between Actual and Preferred environments, gender differences in perceptions of Actual and Preferred environment, the relationship between the science laboratory environment and attitude towards science laboratory work, differences between school and university laboratory classes, differences between teachers’ and students’ perceptions of the same laboratory classes, and differences between laboratory classes in different science subjects (Physics, Chemistry, Biology).

Development of student inquiry skills in a computerised classroom environment

This paper discusses a study in progress which involves the use of a computerised research science database (Birds of the Antarctica) and specially designed curriculum materials. The purpose of the study is to investigate the extent to which students’ inquiry skills can be facilitated by the materials. Much attention is given in the programme to developing both students’ inquiry skills and their subject-matter knowledge. Year 11 and 12 students’ knowledge and skills development are interpreted as they interact with the computerised database and the curriculum materials. Preliminary findings about students’ abilities and perceptions are discussed and, in particular, constraints to the development of inquiry skills and construction of understanding are explored. Specializations: Science education, computers in education, learning environment.     

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.

Student gender, school size and changing perceptions of science learning environments during the transition from primary to secondary school

This study investigated students’ perceptions of the generalist learning environment of the primary school compared to their perceptions of the specialist science learning environment of secondary school. The role of student gender and change in school size as influencing factors on changes in students’ perceptions across primary to secondary transition were especially considered. The same students’ perceptions of the learning environment were collected in the final stages of primary school and again after their initial term in secondary school. Insights were gained into how students’ perceptions of learning environment changed during their first exposure to specialised science learning environments and teachers, and how these changes in perceptions during transition depended upon school size and student gender. Both school size and student gender were found to be influencing factors for changes in some learning environment dimension perceptions.     

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.

A learning model for science education: Deriving teaching strategies

A learning model for science education was proposed by Appleton (1989), based on Osborne and Wittrock’s generative learning theory (1983) and the Piagetian notions of disequilibrium, assimilation, and accommodation. The model incorporated many aspects of difficulties in learning science experienced by students, as revealed in the LISP projects and similar research. This paper examines how the model may be used to derive teaching strategies: components of the model are analysed in terms of specific types of teacher interventions which could facilitate students’ progress to accommodation. Some established teaching strategies are analysed in terms of these interventions. Specializations: primary teacher education, teaching strategies in science.     

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.     

How confident are primary school teachers in teaching science?

The recent nationalDiscipline Review of Teacher Education in Mathematics and Science outlines the lack of confidence of many preservice primary school teachers in teaching science. This study explores the attitudes of 170 primary school teachers in a Perth school district. By means of a simple questionnaire the perceptions and attitudes of these teachers about the following aspects have been examined: (1) background understanding of science; (2) preservice training; (3) interest in teaching science; (4) skill in teaching science; (5) confidence in the plant, animal, matter, energy areas, and (6) time spent teaching science. Besides compiling frequency responses for all teachers on these aspects comparisons have also been made on the basis of: (1) gender; (2) time of graduation, and (3) grade level taught.

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.     

Learning in science project (teacher development): The framework

The Centre for Science and Mathematics Education Research at the University of Waikato is now undertaking the fourth Learning in Science Project, LISP(Teacher Development). The project builds on the findings of the previous three projects on the nature of learning and how to improve learning of science in classrooms. This two-year project is investigating the process of teacher development (as change in behaviour and beliefs) in the context of two kinds of teacher courses that acknowledge and take into account teachers’ existing ideas. This paper summarises the planning done for the first phase of the project as detailed in Bell, Kirkwood and Pearson (1990). Specializations: learning theories, curriculum development, equity issues. Specializations: science education, teacher professional development.     

Researching balance between cognition and affect in science teaching and learning

This paper is based on findings from a three year collaborative action research project on classroom teaching and learning. The research, which involved 33 teachers, over two thousand students from six schools, and the authors, centred on exploring how various features of the classroom context influence teaching and learning processes. We interpret project findings as indicating the importance of balance between cognition and affect for effective teaching and learning. We advance the notion of challenge as a way of conceptualising this balance. Challenge comprises a cognitive/metacognitivedemand component and an affectiveinterest component. Nine major features of a teaching/learning event were found to interact to influence these cognitive and affective components of challenge. Specializations: Collaborative research on science teaching and learning; staff development and school improvement; quality of science education. Specializations: Learning and teaching science; pre-service teacher education. Specializations: teacher development in science education; technology education. Specializations: Science and teachnology curriculum, environmental education, educational disadvantage. Specializations: learning theory, probing of understanding, conceptual change.     

New data and prior belief: The two faces of scientific reasoning

Kuhn (1989) has argued that at the heart of the ability to reason scientifically is the process of differentiating existing mental models (i.e. theory) from new data. In this regard she has proposed a developmental sequence in which, in the early stages, theory and data are fully integrated and are used interchangeably. Later, when theory and data are compatible, they tend to be moulded together as ‘the way things are’, but when they are incompatible conflict is avoided by the use of strategies which bring the two into line: these strategies often include selective attention to the data. Only at the upper levels of this developmental spectrum are theory and data conscientiously differentiated, with each being used to reflect on the other. This paper analyses the responses made by Year 11 students to problems which required them to evaluate a prediction based on some provided data. The problems were set in two contexts, one scientific and one social, and the predictions to be evaluated combined plausibility/implausibility and validity/invalidity. The response patterns were very similar to those described by Kuhn, and the implications of this for teachers, especially those attempting to use conflict based teaching approaches, are developed.

Urban Students’ Perceptions of Teachers: Views of Students in General, Special, and Honors Education

Students’ satisfaction with school experiences has been linked to their sense of belongingness, connection to school, and achievement. Though the extant research addresses students’ perceptions of school climate and sense of belonging, there is a paucity of research about students’ views of teacher–student interactions. Five hundred and seventy-seven students from one ethnically and academically diverse urban high school were surveyed and interviewed about the nature of teacher talk with students. Findings from this mixed-methods investigation indicate students from general, special, and honors programs experience a wide range of interactions based on academic services received, gender, and ethnicity. More frequent perceived punitive feedback was reported by all students in special education as well as males in general and honors education programs, while Hispanic students indicated a greater frequency of perceived supportive feedback. Findings also reflect a wide range of attitudes and feelings about teachers, the educational system, and learning.     

Misconceptions and light: A curriculum approach

This paper describes the method used by the author to teach a class of Year 8 students about light and its properties so that the students’ own ideas were considered and their misconceptions addressed. To achieve this a series of teaching modules were designed using a model of conceptual change suggested by Posner and his colleagues at Cornell University. Students’ prior misconceptions about light were identified using a pretest developed by the author. After teaching a posttest was used to determine if the teaching method resulted in a lower level of misconceptions. Interviews from seven students selected at random and the observations gathered by a participant observor were used to verify results. It was found that the teaching method resulted in a lower level of misconceptions in the sample and this was confirmed by the results of the interviews and participant observation. This paper concentrates on the design and content of one of the teaching modules. Specializations: students’ misconceptions in science.     

One Science Teacher’s Professional Development Experience: A Case Study Exploring Changes in Students’ Perceptions of Their Fluency with Innovative Technologies

The purpose of this case-study is to narrate a secondary science teacher’s experience of his professional development (PD) education and training in innovative technologies (IT) in the context of engaging students in environmental research projects The sources from which the narrative is derived include (1) the science teacher’s reflective reports during three summer institute programs and (2) the science teacher’s reflective reports while subsequently engaging students in IT-embedded environmental research projects in his classroom. The science teacher’s explanations for changes in students’ perception of their IT fluency illuminate his personal narrative. The science teacher attributed his growth and significant changes in students’ perceptions of their IT fluency to the following mechanisms: (a) a personal commitment to developing his own and his students’ IT abilities in the context of doing environmental research projects, and (b) an increase in class time devoted to science education due to school-time scheduling policy. The study implies that immersive professional development opportunities have the potential to produce significant increases in students’ perceptions of their IT fluency.     

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.

UNDERSTANDING STUDENTS�� OUT-OF-SCHOOL MATHEMATICS AND SCIENCE PRACTICE

This study examined standard 6 and 8 (Standards 6 and 8 are the sixth and eighth years, respectively, of primary level schooling in Kenya.) students’ perceptions of how they use mathematics and science outside the classroom in an attempt to learn more about students’ everyday mathematics and science practice. The knowledge of students’ everyday mathematics and science practice may assist teachers in helping students be more powerful mathematically and scientifically both in doing mathematics and science in school and out of school. Thirty-six students at an urban school and a rural school in Kenya were interviewed before and after keeping a log for a week where they recorded their everyday mathematics and science usage. Through the interviews and log sheets, we found that the mathematics that these students perceived they used outside the classroom could be classified as 1 of the 6 activities that Bishop (Educ Stud Math 19:179–191, 1988) has called the 6 fundamental mathematical activities and was also connected to their perception of whether they learned mathematics outside school. Five categories of students’ perceptions of their out-of-school science usage emerged from the data, and we found that 4 of our codes coincided with 2 activities identified by Lederman & Lederman (Sci Child 43(2):53, 2005) as part of the nature of science and 2 of Bishop’s categories. We found that the science these students perceived that they used was connected to their views of what science is.     

Classroom learning experiences and students’ perceptions of quality of school life

It is generally believed that classroom learning experiences very much influence students’ academic development. However, relatively little is known about whether classroom learning experiences have much effect on students’ affective and social development. In this study, we argued for the importance of learning experiences on students’ affective and social development. From research on Accelerated Schools Project and active learning, we conceptualised Positive Learning Experiences, Teacher Support in Learning, and Active Learning Experiences as three components of learning experiences and developed relevant measures to tap these learning experiences. Using research data from a large-scale student survey in Hong Kong (N = 19,477), we examined the construct validity of learning experiences and quality of school life. Confirmatory factor analysis provided very strong support for the measures and the underlying constructs that they tap. In two-way analysis of variance, the effects of gender and school level (secondary versus primary) on learning experiences and quality of school life were examined. Significant gender and school-level main effects, as well as gender by school-level interaction effects, were found for students’ ratings of their learning experiences and quality of school life. Female students gave more favourable ratings than male students, and primary students gave more favourable ratings than secondary students. In addition, gender differences in these ratings in secondary schools were relatively smaller than in primary schools. In subsequent multilevel modelling, learning experiences were strong predictors of quality of school life after controlling for the effects of gender, school level and average school achievement. These findings provide strong empirical support for the significance of classroom learning experiences for students’ social and affective development.
