A comparison of primary school pupils' ability to express procedural understanding in science through speech and writing

In this article the answers provided by 98, 12-year-old students to questions included in an end-of-year science examination are analysed. Almost all of the students are able to explain day and night, but the reason why the Moon always presents the same face to the Earth is less well understood. Estimations of the time in Earth days from sunrise to sunrise on the Moon vary. Most students can explain the apparent movement of stars across the night-sky, but their direction is less certain. Implications of the findings for teaching and learning are addressed.

Effect of computer interfaces on chemistry problem solving among various ethnic groups: A comparison of Pen-Point and Powerbook computers

This study investigated the effect of Pen-Point and Powerbook computers on solving a multiple step chemistry (molaritý) problem among White, Afro-American and Hispanic students (N=60) at the high school level. The screens on both computers were partitioned into a work field and a reasoning field. Both computers were programmed to record the time spent in each field, the number of entries made, and a copy of the entries made. Statistical analysis of data showed that more of the White and Afro-American Pen-Point computer users solved the problem correctly than did students using the Powerbook computer. All three ethnic groups made fewer entries, and took less time using the Pen-Point computer than the Powerbook. Attitude survey results of all ethnic groups showed that more Pen-Point computer users felt comfortable working with computers. Over all, the results suggest that the Pen-Point computer has a more positive effect on the problem solving performance and attitude of students towards computers than the Powerbook computer.     

Using action research as a methodological tool: understanding teachers' understanding of science

A series of questions and answers between Jennifer Nias in her role as supervisor and Steve Waters-Adams as student explores the rationale for the inclusion of action research as a methodological tool within a wider PhD study. The study explored the effect of teachers' understanding of the nature of science on their teaching. In discussing the complexities of the research, Steve Waters-Adams suggests that action research provided a powerful means of gaining access to important tacit and dialectical aspects of teachers' practice. The discussion considers the process of action research, particularly with regard to the extent that its form and purpose may be defined, the importance of collaboration and the centrality of personal commitment. Steve Waters-Adams concludes that there is scope for subject-oriented research in education to make more use of action research as a methodological tool, given that the process engages with, and exposes for scrutiny, practitioners' values, aims and motives.

Public understanding of science: from contents to processes

Public understanding of science is commonly seen in terms of lay persons' understanding of the contents of science. This article argues that it may be more salient to consider public understanding of the internal processes of science ‐ of the nature of scientific knowledge and of the sorts of information that science can reasonably be expected to provide. Drawing on the reported statements of non‐scientists in the media following the Chernobyl nuclear reactor accident, the article argues that the view of scientific knowledge that many people appear to hold is not one that can help them interpret and cope successfully with sts issues. The role that formal science education plays in sustaining this unhelpful view of science is discussed and some implications for practice are considered.     

A theoretical understanding of the literature on student voice in the science classroom

Background: Incorporating student voice into the science classroom has the potential to positively impact science teaching and learning. However, students are rarely consulted on school and classroom matters. This literature review examines the effects of including student voice in the science classroom.

Purpose: The purpose of this literature review was to explore the research on student voice in the science classroom. This review includes research from a variety of science education sources and was gathered and analyzed using a systematic literature review process.

Design and methods: I examined articles from a variety of educational journals. I used three key terms as my primary search terms: student voice, student perceptions, and student perspectives. The primary search terms were used in conjunction with qualifiers that included science education, science curriculum, student emergent curriculum, student centered curriculum, and science. In order to be included in the literature review, articles needed to be published in peer-reviewed, academic journals, contain clearly defined methods (including quantitative, qualitative, or mixed methods), include research conducted in K through 12 classrooms, include the term ‘student voice’, and focus specifically on science. I included articles from a variety of science classrooms including general middle school science, science-specific after-school programs, secondary science classrooms in a variety of countries, and physics, biology, and aerospace classrooms. No restrictions were placed on the country in which the research was conducted or on the date of the research.

Conclusions: The results of the literature review process uncovered several themes within the literature on student voice. Student voice research is situated within two main theoretical perspectives, critical theory and social constructivism, which I used as the main themes to structure my findings. I also identified subcategories under each main theme to further structure the results. Under critical theory, I identified three subcategories: determining classroom topics, developing science agency, and forming identities. Under social constructivism, I discovered four subcategories: forming identities, incorporating prior knowledge and experience, communicating interest in topics and classroom activities, and improving student–teacher relationship. The research supports that allowing students a voice in the classroom can lead them to feel empowered, able to construct their own meaning and value in science, demonstrate increased engagement and achievement, and become more motivated. I conclude students should be allowed a voice in the science classroom and to continue to ignore these voices would be a disservice to students and educators alike.     

Robotics and science literacy: Thinking skills,science process skills and systems understanding

This paper reports the results of a study of the relationship of robotics activity to the use of science literacy skills and the development of systems understanding in middle school students. Twenty‐six 11–12‐year‐olds (22 males and 4 females) attending an intensive robotics course offered at a summer camp for academically advanced students participated in the research. This study analyzes how students utilized thinking skills and science process skills characteristic of scientifically literate individuals to solve a robotics challenge. In addition, a pre/post test revealed that course participants increased their systems understanding, t (21) = 22.47, p < .05. It is argued that the affordances of the robotics environment coupled with a pedagogical approach emphasizing open‐ended, extended inquiry prompts the utilization of science literacy‐based thinking and science process skills and leads to increased systems understanding. © 2008 Wiley Periodicals, Inc.

Environmental Literacy: Towards a shared understanding for science teachers

This article describes an enquiry into education for environmental literacy by a group of secondary school science teachers in the UK as part of a professional development programme. Using participatory action research approaches, the teachers explored ways of maintaining and enhancing the integrity of their subject discipline yet contributing to education for sustainable development. A knowledge- and skills-based model, with a hierarchical structure, was postulated to explain how science education could provide important elements to an overall environmental literacy for their students. Other educational qualities were identified as being essential and the pedagogical implications were explored giving examples of how these might be developed as specific methodologies. The final evaluation of the learning experience by the teachers showed that they found that the approach used here helped them to address their needs, particularly with regard to analysis of pedagogy.     

A comparison of level of understanding of eighth‐grade students and science student teachers related to selected chemistry concepts

The aim of this study is to investigate and compare level of understanding of eighth‐grade students and student teachers in their final year in the science education department related to concepts of solution, gas, and chemical change. A qualitative and quantitative methodology was used for this investigation. Open‐ended questions and group discussion methods were used for data collection. Moreover, to examine how students visualize these concepts, students were asked to make drawings. The questions were administered to 50 students in Grade 8 and 50 student teachers in the science education department. Group discussions were conducted with 6 students and 6 student teachers. There were surprisingly similar alternative conceptions by both the students and the student teachers despite more instruction on these topics in the education of the student teachers. Based on the results, some suggestions are presented. © 2005 Wiley Periodicals, Inc. J Res Sci Teach     

Jordanian and Malaysian science teachers' prominent perceived professional needs: A comparison

The prominent perceived professional needs of 365 Jordanian and 1,162 Malaysian secondary-level science teachers were examined using the Science Teacher Inventory of Need. These were compared across subgroups of the respective samples and across the two samples. The Jordanian science teachers' needs were in the areas of delivering science instruction, managing science instruction, administering science instructional facilities and equipment, and improving one's competence as a science teacher. The Malaysian science teachers' needs came from those four areas plus the area specifying objectives for science instruction. Needs from the first four areas were shared across the two samples. These needs were similar to ones observed in U.S. samples. The reason for the similarities is questioned.
