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.     

The education of children with special needs: a cross‐cultural perspective

ABSTRACT

This paper discusses issues attendant on the practice of identifying pupils with special educational needs in advanced educational systems. Current practices in Australia and Scotland are described and attention is drawn to the problems generated by the abandonment of a category‐based approach to children with special educational needs, the variability of practice between authorities and the absence of reliable data on incidence of special educational needs. Placement outcome data derived from a Scottish study are presented and discussed. The paper concludes with discussion of Australian and Scottish practice set against United States’ experience in the light of Public Law 94‐142 and identifies areas for future research.     

Teacher candidates' growth in designing mathematical tasks as exhibited in their lesson planning

Abstract

In order to gain insight into preservice teachers' beliefs about planning for mathematics instruction, a study was carried out involving K‐8 teacher candidates enrolled in an elementary mathematics methods course. Doyle's (1992) notion of academic task and the research on pedagogical content knowledge served as the theoretical framework for this study. The teacher candidates submitted lesson plans at three intervals during a semester‐long methods course; the lesson plans were then coded based on candidates' planned uses of academic tasks. Analyses of the data revealed trends in these teacher candidates' design of academic tasks over the course of the semester. Recommendations and implications are pre‐sented highlighting the benefits of incorporating the knowledge base on academic task into a mathematics methods course as a means to con‐tribute to teacher candidates' developing pedagogical content knowledge via their designing of academic tasks in lesson planning.     

Teacher preparation to proficiency and beyond: exploring the landscape

Concerns around the provision and retention of quality teachers are global. Amongst these concerns are the preparedness of graduate teachers and the quality and nature of teacher education. The purpose of the article is to focus questions of teacher preparedness and education within a wider discussion around the professional life-cycle of teachers. Initial teacher education is viewed as the first phase of the professional life-cycle of a teacher; part of a professional continuum of learning and expertise, rather than a distinct preparatory phase. We do not present a detailed model for this continuum; believing there is still significant work to be done on defining and delineating the levels of expertise. Such work is beyond the scope of this paper. We do provide a starting point for further consideration. Further, we suggest a scaffolded transition, determined by the learning needs of teachers, between initial teacher education and induction, moving to in-service learning, with closer connections between providers and schools to mitigate against a disconnect between these phases of development. The potential role of professional standards in supporting teacher learning across the professional life-cycle is also discussed.     

Knowing in primary physical education in the UK: negotiating movement culture

This paper aims to understand how pupils and teachers actions-in-context constitute being-a-pupil and being-a-teacher within a primary school physical education (PE) movement culture. Dewey and Bentley's theory of transaction, which views organism-in-environment-as-a-whole, enables the researcher to explore how actions-in-ongoing activities constitute and negotiate PE movement culture. Video footage from seven primary school PE lessons from a school in the West Midlands in the UK was analysed by focusing upon the ends-in-view of actions as they appeared through the educational content (what) and pedagogy (how) of the recorded PE experiences. Findings indicated that the movement culture within the school was a monoculture of looks-like-sport characterised by the privileging of the functional coordination of cooperative action. Three themes of pupils' and teachers' negotiation of the movement culture emerged U-turning, Knowing the game and Moving into and out of games. This movement culture required teachers to ensure pupils looked busy and reproduced cooperative looks-like-sport actions. In fulfilling this role, they struggled to negotiate between their knowledge of sport-for-real and directing pupils towards educational ends-in-view within games activities. Simply being good at sports was not a prerequisite for pupils' success in this movement culture. In order to re-actualise their knowledge of sport, pupils were required to negotiate the teacher's ‘how’ and ‘what’ by exploring what constituted cooperative actions within the spatial and social dimensions of the activities they were set. These findings suggest that if PE is to be more than just the reproduction of codified sport, careful adjustment and consideration of ends-in-view is of great importance. Without regard for the latter there is potential to create significant complexity for both teachers and pupils beyond that required by learning and performing sport.     

Articulation Visibility at Two-Year Colleges

Articulation between two-year colleges and universities provides a critical opportunity for potential students. Most institutions declare their support of articulation; however, the visibility of this support to potential students is inconsistent at best. Articulation agreements that are visible and easily understood by potential students serve as a motivation to the pursuit of higher education. Conversely, the lack of a complete, visible path to a baccalaureate degree is a powerful deterrent to enrollment. For this study, articulation is a coordinated effort and process to support efficient transfer between institutions of higher education. (DeMott, 1999 DeMott , J. ( 1999 ). Seven steps to articulation success . High School Magazine , 6 , 22 – 24 . [Google Scholar]). The purpose of this study is to explore the general visibility of existing articulation opportunities at two-year colleges. The visibility of articulation agreements is a critical practical factor in their potential positive impact on student behavior and success.     

An NCME Instructional Module: Guidelines for the Development of Item Banks

Use of item banking technology can provide much relief for the chores associated with preparing assessments; it may also enhance the quality of the items and improue the quality of the assessments. Item banking programs provide for item entry and storage, item retrieval and test creation, and maintenance of the item history. Some programs also provide companion programs for scoring, analysis, and reporting. There are many item banking programs that may be purchased or leased, and there are banks of items auailable for purchase. This module is designed to help those who develop assessments of any kind to understand the process of item banking, to analyze their needs, and to find or develop programs and materials that meet those needs. It should be useful to teachers at all leuels of education and to school-district test directors who are responsible for developing district-wide tests. It may also provide some useful information for those who are responsible for large-scale assessment programs of all types.
