Chemistry Teachers’ Emerging Expertise in Inquiry Teaching: The Effect of a Professional Development Model on Beliefs and Practice

This study investigates the beliefs and practices of seven high school chemistry teachers as a result of their participation in a year-long inquiry professional development (PD) project. An analysis of oral interviews, written reflections, and in-class observations were used to determine the extent to which the PD affected the teachers’ beliefs and practice. The data indicated that the teachers developed more complete conceptions of classroom inquiry, valued a “phenomena first” approach to scientific investigations, and viewed inquiry approaches as helpful for facilitating improved student thinking. Analysis of classroom observations with the Reformed Teaching Observation Protocol indicated that features of the PD were observed in the teachers’ practice during the academic year follow-up. Implications for effective science teacher professional development models are discussed.

Alternative Conceptions of Organic Chemistry Topics among Fourth Year Chemistry Students

This study describes the conceptual understanding for a series of fundamental organic concepts by fourth year chemistry students from a midsize, southeastern, state university. Student volunteers (n =19) participated in semi-structured interviews using a think aloud protocol. The interview questions were eleven multiple choice questions selected from the Organic Chemistry examination developed by the Examinations Institute of the Division of Chemical Education, American Chemical Society. The questions were chosen to represent a range of concepts that are fundamental to the organic chemistry course sequence. Analysis of the interview transcripts revealed trends in the students’ knowledge and alternative conceptions. Of particular interest, it was found that some alternative conceptions mirrored those previously seen with students in introductory chemistry, indicating the persistence of such alternative conceptions. Implications for instructional approaches particular to organic chemistry are discussed.

Teacher Enactment Patterns: How Can We Help Move All Teachers to Reform-Based Inquiry Practice Through Professional Development?

The purpose of this study was to investigate high school teachers’ beliefs about inquiry instruction and determine how their beliefs influenced their use of inquiry after a professional development program. Thirty-six high school science teachers participated in this study. The professional development program consisted of a 2-week summer institute as well as academic year support. The summer program included discipline-specific content lessons that utilized inquiry-based instruction, pedagogical practice involving the use of a summer high school enrichment program, and reflection on this practice-teaching in content area groups. Both in-depth qualitative interview and written reflection data were collected as well as data from the teachers’ classroom implementation of inquiry. Based on the analysis of the teachers’ interviews and classroom enactments, the teachers were placed into four enactment categories: Integrated, Emerging, Laboratory-based, and Activity-focused. We used Windschitl’s (Rev Educ Res 72(2):131–175, 2002) four constructivist dilemmas as a framework to understand the teachers’ enactments. We describe the teachers’ beliefs and practices in each enactment category as well as the components of the professional development model that were important to making changes in the teachers’ practices. In the conclusion, we connect the enactment levels to the professional development experience and suggest future directions for professional developers to move teachers toward more integrated inquiry practices.

Stemming the Diffusion of Responsibility: A Longitudinal Case Study of America’s Chemistry Teachers

National initiatives to expand the aggregate science, technology, engineering, and math (STEM) workforce reflect America’s goals to increase global competitiveness. However, the aggregation of STEM stakeholders may elicit a diffusion of responsibility because individuals assume others are already acting. Here, we perform a longitudinal case study of U.S. public school chemistry teachers to illustrate a diffusion of responsibility within the STEM community regarding who is responsible for the teacher workforce. Utilizing the 1987–2007 Schools and Staffing Survey (SASS) data, we determine how chemistry teacher demographics compare to other disciplines. Our results suggest that the aggregate success of STEM education initiatives may mask the need for discipline-specific reform. We describe reforms in the context of boundary objects and discuss implications for policy decisions as boundary crossings.

Pushing for particulate level models of adiabatic and isothermal processes in upper-level chemistry courses: a qualitative study

In the past three decades, researchers have noted the limitations of a problem-solving approach that overemphasizes algorithms and quantitation and neglects student misconceptions and an otherwise qualitative, conceptual understanding of chemical phenomena. Since then, studies and lessons designed to improve student understanding of chemistry has overwhelmingly targeted introductory level, high school and first-year college students. In this article, we present a model-based learning cycle approach with upper-level undergraduate and beginning graduate students that investigated their ability to model the adiabatic and isothermal compression/expansion of a gas in a syringe. We were interested to observe, given the extent of their previous chemistry coursework, how students struggled to connect macroscopic observations with particulate representations. Analysis of laboratory reports, reflective journal entries, and classroom discourse transcripts indicate the learning experience was efficacious in uncovering and addressing student conceptual challenges with using models appropriately to describe gas behaviour under the experimental conditions for this investigation.

Plugging the ‘Leaky Bucket’ of Early Career Science Teacher Attrition through the Development of Professional Vision

The demand for a qualified, competent, and stable K12 science teaching workforce is being emphasized now more than ever. Widespread dissemination and discussion of reports from the National Academies (Augustine, 2005; Committee & Medicine, 2010), President’s Council of Advisors on Science and Technnology (PCAST; Lander & Gates Jr., 2010), and even directly from the White House (Larson, 2012) attest to this fact.

Connecting Research to Practice for Better Beginnings

This book adds to the current discussion about newly hired science teachers. Collectively, the authors provide insights that are related to both research and practice. The research suggestions emerge from studies of new teachers, while the practical side of this book presents approaches to supporting new teachers that are grounded in research. Within these two dimensions, there is an emerging theory about supporting new teachers in order to ensure their ongoing professional development.
