Air Toxics Under the Big Sky: examining the effectiveness of authentic scientific research on high school students’ science skills and interest

Air Toxics Under the Big Sky is an environmental science outreach/education program that incorporates the Next Generation Science Standards (NGSS) 8 Practices with the goal of promoting knowledge and understanding of authentic scientific research in high school classrooms through air quality research. This research explored: (1) how the program affects student understanding of scientific inquiry and research and (2) how the open-inquiry learning opportunities provided by the program increase student interest in science as a career path. Treatment students received instruction related to air pollution (airborne particulate matter), associated health concerns, and training on how to operate air quality testing equipment. They then participated in a yearlong scientific research project in which they developed and tested hypotheses through research of their own design regarding the sources and concentrations of air pollution in their homes and communities. Results from an external evaluation revealed that treatment students developed a deeper understanding of scientific research than did comparison students, as measured by their ability to generate good hypotheses and research designs, and equally expressed an increased interest in pursuing a career in science. These results emphasize the value of and need for authentic science learning opportunities in the modern science classroom.     

Whose reality counts? Local educators as researchers on the quality of primary education

This article describes a methodology that local educators can use to conduct structured analytic research on the quality of primary education. The methodology has been developed by four twenty-person teams of local educators who carried out studies in rural regions of Madagascar, Mozambique, Tanzania and Uganda. In addition to describing the methodology, the article presents short summaries of the researchers’ conclusions and recommendations. However, its main purpose is to share the methodology that has evolved. The methodology is qualitative, but a simple quantitative measure of relationship between binary variables (Yule’s Q) was used to test the researchers’ qualitative findings. It is this tool that provoked the most significant reflection among the researchers in each group. In general, the results of the four studies corroborate other research on the factors that influence student outcomes in primary schools in Sub-Saharan Africa. More importantly, the studies’ results demonstrate that the methodology offers practicing educators a tool that helps them define, collect, and rigorously analyse empirical information to reach shared insights about their schools and then to formulate practical recommendations about what to do to improve student learning.     

Integration of Mildly Handicapped Cerebral Palsied Children into Regular Schools

Eighty‐five mildly handicapped cerebral palsied children integrated into regular schools were assessed in order to identify characteristics associated with academic success and social acceptance. About 50 percent of the children were successful in reading accuracy and comprehension, 45 percent in arithmetic and 60 percent were socially acceptable to peers. Academic achievement was associated with cognitive ability rather than with degree of handicap, while social acceptance was related to affective variables. Cognitive, affective and behavioural mean scores were all within the normal range. Commonality analysis of data derived from the experimental subjects and a contrast group enrolled in a special school indicated that educational placement did not contribute significantly to academic success.     

Computer ethics: Its birth and its future

This article discusses some``historical milestones' in computer ethics, aswell as two alternative visions of the futureof computer ethics. Topics include theimpressive foundation for computer ethics laiddown by Norbert Wiener in the 1940s and early1950s; the pioneering efforts of Donn Parker,Joseph Weizenbaum and Walter Maner in the1970s; Krystyna Gorniak's hypothesis thatcomputer ethics will evolve into ``globalethics'; and Deborah Johnson's speculation thatcomputer ethics may someday ``disappear'.     

Increasing public understanding of transgenic crops through the World Wide Web

Transgenic crops among the most controversial "science and society" issues of recent years. Because of the complex techniques involved in creating these crops and the polarized debate over their risks and beliefs, a critical need has arisen for accessible and balanced information on this technology. World Wide Web sites offer several advantages for disseminating information on a fast-changing technical topic, including their global accessibility; and their ability to update information frequently, incorporate multimedia formats, and link to networks of other sites. An alliance between two complementary web sites at Colorado State University and the University of Nebraska-Lincoln takes advantage of the web environment to help fill the need for public information on crop genetic engineering. This article describes the objectives and features of each site. Viewership data and other feedback have shown these web sites to be effective means of reaching public audiences on a complex scientific topic.     

A comparative study of students' and their teacher's perceptions of laboratory work in secondary schools

This article reports on a study of student and teacher perceptions of the purpose and effectiveness of laboratory work in science at the Year 10 level of secondary school. The main focus of the study was a comparison between the perceptions of one class of students and their teacher at each of six different schools with regard to the aims, regularity, conduct and assessment of laboratory work. The study identified a number of areas of mismatch between students and their teachers. The findings of the study will be of use to teachers in developing and improving their science curriculum, particularly with regard to laboratory work.     

A review of the research of Ference Marton and the Goteborg Group: A phenomenological research perspective on learning

This article reviews the work of Ference Marton and his group of researchers at the University of Goteborg in Sweden. It describes and explains research into: what students learn; how students approach studying; the relationship between approach to study and learning outcomes; what students understand learning to consist of; and whether it is possible to manipulate students' approach to studying in order to influence the learning outcomes. This review is intended to build up an overall picture of learning as seen from a phenomenological research perspective.     

Meritocracy,deficit thinking and the invisibility of the system: Discourses on educational success and failure

Socio‐ethnic stratification and segregation processes present in Flemish society are reflected in the everyday school environment. Pupils with a different socio‐ethnic background than the dominant majority and middle class seem to be confronted with a lot of difficulties in this school system. The dominant meritocratic discourse frequently applies a deficit thinking perspective to frame educational success and failure, focusing on deficiencies originating outside of the school. In this paper we analyse newly collected survey data (N = 11,015 pupils) and a large amount of qualitative data (from pupils, parents, teachers, principals) to answer our two main research questions: (i) how is educational success/failure defined, and (ii) how is educational success/failure explained? The factor analyses as well as the qualitative analyses illustrate how the idea of meritocracy relates to individualistic features such as effort, merit and competence. However, the findings also reveal that this individualistic approach goes hand‐in‐hand with a focus on the family environment and ‘culture’ which seems to limit individual agency to a large extent. In these discourses, pupils, parents and even teachers are presented as being largely determined by their direct social environment with almost no regard for social inequalities within the educational system. The paper ends with a discussion on how processes of victimization and the denial of systemic bias, influence educational trajectories and proposes a different approach to multiculturalism and the appreciation of cultural background and specific family resources as positive elements in these trajectories.     

Principals’ Attitudes Towards the Integration of Disabled Children into Regular Schools

Principals from N.S.W. government and non‐government schools were surveyed to elicit their attitudes towards the integration of individual disabled‐children and the support services currently provided. Attitudes forwards mildly intellectually handicapped students in particular were also examined. Analysis of principals’ ratings for each educational/behavioural disability specified indicates that they are positive only about integrating children who demand neither extra competencies nor extra curricular duties from the regular class teacher. Results also suggest that principals are dissatisfied with the quality and quantity of support services routinely provided and now seek resource personnel with the expertise to directly assist the regular teacher in the classroom. Sub‐group variations among principals on both issues are also reported. Data on mildly intellectually handicapped students indicate little attitudinal change since a study undertaken in 1978, although knowledge of the most effective support services for this population appears to have increased. Implications of these findings for policy and practice are discussed.     

The Nowicki Locus of Control Scales: An Australian Study of Normal and Cerebral Palsied School Children

Mildly handicapped cerebral palsied (CP) children integrated into regular schools were measured on locus of control scales to test the hypothesis that physically disabled children with possible academic difficulties display a more external locus of control than their unimpaired peers. The contribution of this construct to their academic and social performance was also examined. As local norms for these scales were not available, mean grade values were obtained for all children in classes in which a handicapped child had been integrated in order to study the psychometric properties of the scales and the construct's cross‐cultural implications. Results indicated that the instrument did not differentiate between mildly handicapped CP children integrated into regular schools and their non‐disabled peers nor was it a significant correlate of academic or social performance for the target group. Although the possibility exists of real cross‐cultural difference between American and Australian school children, the doubtful reliability and validity of the measure for the population sampled do not support its widespread use as a research instrument with Australian school children.
