Reading and listening at three school stages: cloze tests and their response analysis

This paper reports the results of cloze tests in the reading and listening modes together with a computer analysis of responses to the tests. The subjects were groups of Scottish school children at the ages of 8-9, 11-12 and 13–14 years sampled over the whole country as part of a national survey of English language; the cloze tests were only a small part of the whole testing programme which also contained three other major reading tests. Approximately 400 subjects took cloze tests in each mode at each age. The test material was the same throughout for all stages tested. Two tests, each containing one narrative and one expository text were used. The mode of presentation did not significantly affect the types of cloze responses offered nor the total scores of the tests at any stage. However, results indicated better performance for older subjects when they read, and for the youngest group when they listened to, expository though not narrative passages. The comparisons of the results for the three different school stages showed continuing interdependence of reading and listening ability through the ages tested. The different cloze response patterns for the two types of text (in either mode) as well as the only moderate correlation between the texts, indicated that success in comprehending narratives may not necessarily transfer to comprehending information.     

Growing the tree of teacher knowledge: Ten years of learning to teach elementary science

Pedagogical content knowledge (PCK) is a much debated and studied construct. In this article, we adopt an all‐embracing view of PCK to examine the development of one elementary science teacher's knowledge over a 10‐year period. We portray this teacher's knowledge at three critical points in her career—as a student teacher, beginning teacher, and established teacher—and represent and analyze the growth of her science PCK using the metaphor of a knowledge tree. The tree metaphor shows that while science knowledge begins as the major branch of science PCK, it is soon overshadowed by the general teaching and interactive knowledge branches of science PCK; however, taken together, all three branches contribute over time to the formation of a healthy, established tree of science PCK. © 2005 Wiley Periodicals, Inc.

College MOON Project Australia: Preservice Teachers Learning about the Moon’s Phases

This paper is a report of the Australian segment of an international multi-campus project centred on improving understanding of the Moon’s phases for preservice teachers. Instructional strategies adopted for a science education subject enabled Australian participants to make extended observations of the Moon’s phases and keep observational data records which were shared in asynchronous on-line discussion with fellow preservice teachers in the USA. An adaptation of an online inventory of lunar phases was completed by participants before and after the observation cycle. The analysis of inventory data showed that although there was statistically significant overall improvement in mean scores for the inventory this could be accounted for by statistically significant increases in only some conceptual domains related to the lunar phases. In addition, the findings indicate that some concepts involved in having a deep understanding of lunar phases can be improved by instruction however, misunderstandings of other concepts involved in lunar phases are difficult to change and may require increased attention to developing students’ visual-spatial capabilities.     

Crossing borders: Learning and teaching primary science in the pre-service to in-service transition

This paper reports on a 4-year longitudinal case study of two Australian primary science teachers during their transition from pre-service to in-service teaching. An analytic framework suggested by Aikenhead (1996) was used to interpret teachers' change and professional growth as instances of sub-cultural border crossing. The same framework provides an opportunity for reflexivity on the part of the researchers in coming to understand their own role in the construction of the borders crossed by beginning teachers. The study examines the hazards encountered by teachers as they cross borders and proposes ways of assisting teachers to manage border crossing into the sub-culture of science teaching.     

Personal inquiry: innovations in participatory design and models for inquiry learning

This paper describes a participatory design approach to the development of inquiry‐based learning supported through a technology toolkit. The work is part of an interdisciplinary project – Personal Inquiry (PI). The paper focuses on the approach we adopted, concentrating in particular on the two mediating artefacts we used to guide and frame the design process during two design workshops. The first mediating artefact used was an inquiry framework developed as part of the wider PI project and the second was Kellett’s enquiry research bubbles, which is a framework to guide enquiry‐based thinking processes. The paper reports on data collected during the workshops and reflects on the value of the approach adopted. The paper also explores the PI‐team’s own reflections on the design process and its role in the overall project.     

Do single-gender classrooms in coeducational settings address boys' underachievement? An Australian study

This paper reports a research project developed in partnership with the Principal and Leadership Team of an Australian secondary school. It monitored a school-based initiative designed to address the underachievement of male students. Students in Year 9 selected single-gender or coeducational classes in mathematics and English during the second half of a school year. Student scores in standardized tests and school-based assessment in these subjects were obtained before and after the establishment of the initiative. Results indicate no significant difference in mathematics achievement that can be attributed to gender or class composition. However, scores in school-based English improved for students in single-gender classes. Improvement for girls in single-gender classes was greater than that for boys in single-gender classes.     

Engaging Pre-Service Teachers in Multinational, Multi-Campus Scientific and Mathematical Inquiry

Pre-service teachers from Texas and Indiana in the United States and from Queensland, Australia, observed the Moon for a semester and compared and contrasted their findings in asynchronous Internet discussion groups. The 188 pre-service teachers were required to conduct inquiry investigations for their methods coursework which included an initial Moon observation assignment, an Internet Moon discussion, and a final project. The Moon context was chosen for its motivating capability, its inherent interdisciplinary makeup, its inclusion in the National Science Education Standards, and its ability to be viewed worldwide. This study was of a mixed method research design and involved pre-service teachers’ journals, summative reflections, Internet discussions, final projects, and the Lunar Phases Concept Inventory (LPCI). Analysis of the qualitative data was conducted through the exploration of patterns and themes that illustrated pre-service teachers’ conceptual development, and the LPCI was administered as a pre/post assessment. We found that our project led to increased knowledge concerning the mathematics and science involved with understanding the Moon and its phases. We also found that it was beneficial to have Internet discussions with pre-service teachers from around the world, but it was not without its problems (e.g., coordinating schedules and lack of participation by some participants). We discovered that pre-service teachers’ exposure to the new uses of technology for teaching and learning did not necessarily translate to their planning to adopt similar techniques in their own classrooms.
