Mature-age students-how are they different?

Mature-age students have formed a significant proportion of preservice students in primary teacher education over recent years. Academic staff have reported a difference between mature-age students and school-leavers, particularly in motivation and achievement. This report examines part of a study which explored mature-age students' views about aspects of teaching science and technology, compared to the views of students who came to university straight from school. It examines, in particular, students' personal feelings of adequacy in teaching science and technology in primary schools. Specialisations: primary teacher education, teaching strategies in science.     

Problem solving in science lessons: How students explore the problem space

This report examines, from a constructivist framework, how students presented with discrepant event problems during science lessons begin the problem solving process by exploration of the problem space. Three discrepant events were presented to five classes of eleven to thirteen year-olds using three different teaching strategies identified from the literature. The teaching strategies used teacher demonstrations followed by students asking the teacher questions, teacher demonstrations followed by an explanation by the teacher, and small groups of students under the guidance of the teacher. Data were collected from field notes, video tapes of the lessons, and student interviews using a stimulated recall technique to elicit the students' thinking during the lessons. The extent to which students could explore the problem space was found to be determined by the teaching strategy used, as the first and last strategies encouraged students to find their own explanations. Different information sources were also available in each of the teaching strategies. That is, exploration of the problem space was inextricably linked to the social context, partially determined by the teaching strategy. Because of constraints imposed by each teaching strategy none of those used was considered entirely satisfactory. An alternative strategy is suggested from a combination of aspects of the strategies trialled.     

Quality of Learning in Nigeria's Universal Primary Education Scheme—1976–1986

The paper critically examines the quality of education in Nigeria's Universal Primary Education (UPE) scheme from 1976 to 1986. The author argues that the positive impact of the UPE scheme was that more people went to school, and many of them can now read and write their names and seem to be better informed. But the standard of Seaming fell far below what it was before the introduction of the UPE scheme in Nigeria. Those who planned the scheme apparently forgot to consider the importance of the availability of qualified teachers, adequate learning environments, equipment and textbooks, classroom management and supervision, and the content of the curriculum. Since availability of the above facilities is integral to effective teaching and classroom performance, the inevitable outcome was the erosion of standards in Nigeria's primary education. The author advises other developing countries to act cautiously when embarking on prestige educational projects, such as the UPE scheme, as a means to combat ignorance and illiteracy. It is also hoped that the Nigerian experience will lead to a further understanding of the postulation by educational analysts of school facilities as major factors in effective teaching and determining the quality of learning in the developing countries.     

Enhancing Elementary Pre-service Teachers’ Plant Processes Conceptions

Researchers examined how an inquiry-based instructional treatment emphasizing interrelated plant processes influenced 210 elementary pre-service teachers’ (PTs) conceptions of three plant processes, photosynthesis, cellular respiration, and transpiration, and the interrelated nature of these processes. The instructional treatment required PTs to predict the fate of a healthy plant in a sealed terrarium (Plant-in-a-Jar), justify their predictions, observe the plant over a 5-week period, and complete guided inquiry activities centered on one of the targeted plant processes each week. Data sources included PTs’ pre- and post-predictions with accompanying justifications, course artifacts such as weekly terrarium observations and science journal entries, and group models of the interrelated plant processes occurring within the sealed terraria. A subset of 33 volunteer PTs also completed interviews the week the Plant-in-a-Jar scenario was introduced and approximately 4 months after the instructional intervention ended. Pre- and post-predictions from all PTs as well as interview responses from the subgroup of PTs, were coded into categories based on key plant processes emphasized in the Next Generation Science Standards. Study findings revealed that PTs developed more accurate conceptions of plant processes and their interrelated nature as a result of the instructional intervention. Primary patterns of change in PTs’ plant process conceptions included development of more accurate conceptions of how water is used by plants, more accurate conceptions of photosynthesis features, and more accurate conceptions of photosynthesis and cellular respiration as transformative processes.     

Changes in primary science over the past decade: Implications for the research community

During the early 1980s in Australia there was a new wave of expectancy about primary science as new curricula were being considered or introduced and research findings were beginning to identify new directions for both teaching and research. In an expression of this, six authors were invited to present papers to a symposium on primary science held in 1984 to address the question: “What do you believe should be the state of primary science (in Australia) in 1995 and what are the steps which need to be taken to achieve the desired state?” This study set out to identify what had been said at that time, to compare that with actual developments, and to identify possible future directions for research. Relevant publications includingResearch in Science Education were analysed as a means of comparing what had happened since 1984 with the hopes of those authors. It was only in the latter half of the decade that some of the scenarios painted by the authors in 1984 began to emerge. A key implication for the research community drawn from the analysis shows that science education researchers have tended to neglect working in collaboration with education departments and authorities for the improvement of primary science education.     

Afro-Caribbean Immigrant Faculty Experiences in the American Academy: Voices of an Invisible Black Population

Afro-Caribbean immigrants have been an integral part of the history and shaping of the United States since the early 1900s. This current study explores the experiences of five Afro-Caribbean faculty members at traditionally White institutions of higher education. Despite the historical presence and influence of Afro-Caribbean communities and the efforts within education systems to address the needs of Afro-Caribbean constituents, Afro-Caribbean faculty members continue to be rendered indiscernible in higher education and to be frequently and erroneously perceived as African–Americans. The study examines the lived experiences of these individuals in the hegemonic White spaces they occupy at their institutions with both White and Black populations. Through their narratives, issues of stereotyping, microaggression, and isolation are addressed. The participants also offer solutions to address these issues by university administrators, department heads, faculty development professionals, diversity officers, policy makers, and other stakeholders. The voices in this study shed light on an overlooked, misunderstood, and under-researched population within our faculty ranks in the American Academy.     

Seeing Is Believing: Effective Components of Professional Development Training for County Extension Educators on an Innovation Perceived as Risky—Food Irradiation

ABSTRACT: Decades of research have provided evidence that food irradiation is a safe technology that can decrease the incidence of foodborne diseases; however, adoption of this technology has been slow. The purpose of our study was to qualitatively explore the effectiveness of various components of a professional development training on family and consumer sciences county extension educators' understanding of food irradiation. This training included presentations by experts in the field, a tour of a food irradiation research facility and a meat processing facility, group activities, and a computer simulation model. Data were collected using qualitative research methodology through in-depth interviews conducted after the training. Results indicated that those components that allowed participants to visualize food irradiation processes seemed most beneficial to their understanding. Based on these data, implications for practice are discussed.     

Journal Editorial Policies Regarding Statistical Significance Tests: Heat Is to Fire as p Is to Importance

The present paper responds to defenses of statistical significance testing offered by Levin and Robinson. First, some inaccurate perceptions of contemporary criticisms of statistical tests are noted. Second, areas of disagreement are explored. For example, it is noted that all nine empirical studies of reporting practices since 1994 show that encouraging (per the 1994 APA style manual) authors to report effect sizes has not worked; two reasons for this failure are explored. Finally, two important areas of agreement regarding needed improvements in contemporary practices are noted.
