Science teacher orientations and PCK across science topics in grade 9 earth science

ABSTRACT

While the literature is replete with studies examining teacher knowledge and pedagogical content knowledge (PCK), few studies have investigated how science teacher orientations (STOs) shape classroom instruction. Therefore, this research explores the interplay between a STOs and the topic specificity of PCK across two science topics within a grade 9 earth science course. Through interviews and observations of one teacher’s classroom across two sequentially taught, this research contests the notion that teachers hold a single way of conceptualising science teaching and learning. In this, we consider if multiple ontologies can provide potential explanatory power for characterising instructional enactments. In earlier work with the teacher in this study, using generic interview prompts and general discussions about science teaching and learning, we accepted the existence of a unitary STO and its promise of consistent reformed instruction in the classroom. However, upon close examination of instruction focused on different science topics, evidence was found to demonstrate the explanatory power of multiple ontologies for shaping characteristically different epistemological constructions across science topics. This research points to the need for care in generalising about teacher practice, as it reveals that a teacher’s practice, and orientation, can vary, dependent on the context and science topics taught.     

Managing oppositional masculinity politics: the gendering of a government-commissioned research project

This article discusses the role of serendipity in qualitative research. Drawing on ideas and methodological suggestions from a set of classic and recent fieldwork accounts, the authors examine conceptions of serendipity and the ways that these conceptions become embedded in the processes by which we incorporate and embrace the temporal, relational, and analytical aspects of serendipity. The authors reject the perspective that it is the divine roll of the dice that determines serendipity and argue that serendipity is the interactive outcome of unique and contingent “mixes” of insight coupled with chance. A wide range of attempts to make sense of serendipity in sociology and anthropology are provided as exemplars of how planned insights coupled with unplanned events can potentially yield meaningful and interesting discovery in qualitative research.     

The Implicit Curriculum in Social Work Education: The Culture of Human Interchange

This article focuses on the culture of human interchange, which is included as a component of the implicit curriculum in the current EPAS. It presents the use of the implicit curriculum concept in teacher and medical education as a context for its application to social work education. The authors argue that professional behaviors taught in the explicit curriculum of the classroom need to be consciously reinforced in the many venues and through the ongoing interpersonal relations throughout the educational environment. The article identifies the challenges that movement in this direction would create but which the implicit curriculum standard mandates us to address.     

Secondary Social Studies Teachers’ Experiences Planning and Implementing Inquiry Using the Inquiry Design Model

While the use of inquiry-based instruction has been encouraged for many years, it continues to be the exception rather than the norm. The publication of the College, Career, and Civic Life (C3) Framework, as well as the Inquiry Design Model that provides structure for its implementation, offer support for teachers to use inquiry in their social studies classrooms. This phenomenological study used semi-structured interviews, classroom observations, and document analyses to explore three secondary social studies teachers’ pedagogical content knowledge as they planned and implemented inquiries. Findings indicate that teachers found a structured method of designing inquiries useful and that their approaches to planning and implementing those inquiries varied with individual context and personal pedagogical stances. There is no one-size-fits-all inquiry, even when teachers used the same support tool.     

Making the conceptual shift: teacher performance appraisal as professional growth

Often, the traditional forms of performance assessment are incongruent with the emerging view of schools as learning organizations. In this pilot study, the authors explored the use of action research as an alternative means of teacher performance appraisal. The findings suggest that action research holds great promise in incorporating teacher learning, continual growth and teacher ownership into the appraisal process. However, this process also necessitated a conceptual shift to connect teacher performance appraisal practices with professional learning.     

Farmers’ Attitude towards a Participatory Research Method Used to Evaluate Weed Management Strategies in Bananas

Abstract

In this study, farmers were engaged in a participatory research project and their attitudes evaluated. The purpose was to identify the characteristics of farmers who are favourably predisposed towards meaningful participation in the process. Several cover crops were tested for possible use in the management of watergrass (Commelina diffusa), a noxious weed in banana cultivation. Small, limited-resource farmers were exposed to the essentials of systematic research through a process of experiential learning using participatory techniques. Thirty-six farmers evaluated three cover crops against the current weed control practice of farmers, which served as the control. Farmers and researchers collaborated on the experimental design, treatment allocation, data to be collected and the form of the analysis. Summary data were subjected by the farmers to the Overlap Test to evaluate differences among the treatments. Results indicated that one cover crop, Desmodium heterocarpon, was better than the others in controlling watergrass. These results were confirmed by ANOVA.

A Likert-type scale, used to assess farmers’ attitude, showed that overall, farmers were generally favourable towards the process. Differences in responses to attitudinal statements were based mainly on farmers’ differing education levels. Some level of attrition was experienced in this process, mainly by the older and more experienced farmers. The younger, less experienced farmers completed the trials to a large extent. The results provide useful information for the selection of farmers to be involved in future participatory technology development initiatives.     

Looking Presidential: A Comparison of Newspaper Photographs of Candidates in the United States and Taiwan

News coverage of elections is a popular topic in mass and political communication research. Studies of this tradition usually focus on news articles and neglect another important element of news content: news photographs. In this study, newspaper photographs of presidential candidates in the United States and Taiwan were compared. Generally, US candidates were more likely to be portrayed as a beloved leader, at leisure, from the side or back, looking determined, as a leader and follower, standing or walking, and with cheering crowds. Candidates in Taiwan were more likely to be depicted in a ‘glad-to-see-you’ pose, with a camera angle looking down, with no expression, as an equal to others in the same photograph, and with inattentive people. How political and cultural differences between these two countries may have contributed to such variations was also discussed in this study.     

Academic optimism of individual teachers: Confirming a new construct

Teacher sense of academic optimism is individual teachers' beliefs that they can teach effectively, their students can learn, and parents will support them so the teacher can press hard for learning. This new construct is grounded in the social cognitive and self-efficacy theories, social capital theory, work on school culture and climate and research on learned optimism. At the school level, collective academic optimism has been related to academic performance (Hoy, Tarter, & Woolfolk Hoy, 2006b). The analyses tested and supported the validity and reliability of the construct at the individual level with elementary school teachers in a confirmatory factor analysis using Structural Equation Modeling (SEM).
