ABSTRACT:In this position paper, we examine the science teaching orientation component of the S. Magnusson, J. Krajcik, and H. Borko (1999) pedagogical content knowledge (PCK) model for science teaching. We trace the origin of the construct in the literature, identifying multiple definitions that have lead to ambiguity. After examining published studies using the PCK model, we identified the following methodological issues: (a) using orientations in different or unclear ways, (b) unclear or absent relationship between orientations and the other model components, (c) simply assigning teachers to one of nine categories of orientations, and (d) ignoring the overarching orientation component. To bring clarity to the literature, we propose defining science teaching orientations as a set of beliefs with the following dimensions: goals and purposes of science teaching, views of science, and beliefs
Alternative certification programs (ACPs) have been proposed as a viable way to address teacher shortages, yet we know little about how teacher knowledge develops within such programs. The purpose of this study was to investigate prior knowledge for teaching among students entering an ACP, comparing individuals with teaching experience to those lacking teaching experience. Of the four participants seeking secondary biology teaching certification, two participants had 2 years of prior biology teaching experience. We used the Lesson Preparation Method as a data collection tool, asking participants to create lesson plans to teach the concept of heritable variation. Primary data sources were the lesson plans and follow-up interview transcripts. Prior teaching experience made little difference as both groups held didactic teaching orientations and wrote similar lesson plans. Both groups drew on general pedagogical knowledge (PK), and had little pedagogical content knowledge for teaching heritable variation. Teaching experience did appear to lead to more integration among PK components. The study includes implications for the teacher education, research, and policy. ß
Socio-scientific teaching and learning (SSI-TL) has been suggested as an effective approach for supporting meaningful learning in school contexts; however, limited tools exist to support the work of designing and implementing this approach. In this paper, we draw from a series of four design based research projects that have produced SSI curriculum materials, research findings, and design insights. The paper describes the creation and evolution of a model for SSI-TL. The model highlights a sequence of learning experiences that should be featured in SSI-TL and the kinds of learning objectives that should result. Student learning experiences should include encountering a focal SSI; engaging in science practices, disciplinary core ideas and crosscutting concepts as well as socio-scientific reasoning practices; and synthesizing key ideas and practices through a culminating exercise. The proposed learning objectives align with Next Generation Science Standards and also reflect the important social dimensions of SSI.
Science teaching orientations, defined as teachers' knowledge and beliefs about the purposes and goals for teaching science, have been identified as a critical component within the proposed pedagogical content knowledge (PCK) model for science teaching. Because of the scarcity of empirical studies in this area, this case study examined the nature and sources of science teaching orientations held by four highly regarded secondary biology teachers. Data sources consisted of transcripts from four interviews, a card‐sorting task, and classroom observations. Using a grounded theory framework, inductive data analysis led to the construction of a substantive‐level theory for this group of participants. In regard to the nature of science teaching orientations, the use of central and peripheral goals, as well as the means of achieving these goals, was used to represent the complex nature of participants' science teaching orientations. The participants' science teaching orientations included goals related to general schooling, the affective domain, and subject matter, although the latter was not always a central component. In regard to the sources of teaching orientations, participants were strongly influenced by the classroom context and their beliefs about learners and learning; additional influences included prior work experiences, professional development, and time constraints. © 2005 Wiley Periodicals, Inc.
