Pre-service Teachers’ Development of Technological Pedagogical Content Knowledge (TPACK) in the Context of a Secondary Science Teacher Education Program
This study explores pre-service teachers’ TPACK development in a secondary science teacher education program that combined a content-specific technology integration course with extensive field experience. Findings indicated that a content-specific technology integration course offered simultaneously with extensive field experience through careful instructional design can improve pre-service teachers’ understanding of combining technology with science content and pedagogy.

Transforming Teachers’ Knowledge Focused on Student Thinking with Technologies Using a Learning Trajectory Instructional Approach
This study explored the influence of a researcher-conjectured learning trajectory instructional approach toward the enhancement of teachers’ technological pedagogical content knowledge (TPACK). The study provides a rich description of how a learning trajectory, situated within a social metacognitive - constructivist instructional framework, influenced the participants’ thinking about their own thinking with the technology in learning mathematics/science and their thinking about their students’ thinking and understanding when learning with the technology. Three themes emerged: The learning trajectory as an ordered network of experiences is multi-faceted; the tools are used for sharing knowledge as well as constructing knowledge; and the tasks sequence the participant in the role of a ‘teacher as a student’ transitioning to the role of ‘teacher as a teacher’.

This article describes the aspects of iPad use which preservice teachers perceived as beneficial in the forces and motion unit. The results revealed that at many stages of this process, the preservice teachers used iPads to abstract ideas from physical experience. Preservice teachers’ responses showed that these experiences were perceived as valuable, both in terms of an understanding of the underlying content and completion of the project as a whole. Additionally, participants described how the iPad influenced instructional efficiency, engagement, and social learning. The authors recommend that it is highly relevant to the development of preservice teachers’ critical pedagogical skills that they confront and discuss both the strengths and weakness of the iPads for various purposes, as well as analyze the way the device shapes student interaction.

The study outlined in this article used the Draw-A-Scientist Test (DAST) to explore the views of scientists held by preservice students in science methods classes at both the elementary and secondary levels. The findings revealed that the students with greater previous science experience at both the secondary and post-secondary level would create visual representations of scientist that were significantly less stereotypical than representations created by students with lesser previous science experience. However, results indicated statistically significant differences in stereotypical components of representations of scientists depending on preservice teachers’ program and previous science experiences.

The purpose of this article is to offer the validity and reliability evidence for teacher science content assessments developed as part of the Diagnostic Teacher Assessments of Mathematics and Science (DTAMS) project. It was found that validity was strengthened by systematic synthesis of relevant documents, extensive use of external reviewers, and field tests with 900 teachers during assessment development process. The subsequent results from 4,400 teachers, analyzed with Rasch IRT modeling techniques, offer construct and concurrent validity evidence.

Religion as a Support Factor for Women of Color Pursuing Science Degrees: Implications for Science Teacher Educators
This study examines the factors women of color utilized as supports as part of their persistence in science majors. This article draws from a larger study of sixteen African-American, Hispanic, and African women who were navigating various undergraduate science majors at multiple colleges in the Northeast and Southeast United States. The findings illustrated that the participants viewed religion as a contributor to general support, stress relief, encouragement during difficult times, and intervention. The author concludes that the findings illustrate that one potential mechanism for broadening science participation may be through connections with students’ families, their cultural backgrounds, and even their religious views.

The authors present a case study of how the core concepts of neuroscience can be brought to in-service teachers—the BrainU workshops. They then discuss how neuroscience can be meaningfully integrated into pre-service teacher preparation, focusing on institutional and cultural barriers.

The main goal of this self-study was to determine the extent to which an instructor's pedagogical knowledge and practice would be enhanced though the use of Just-in-Time Teaching. The findings reveal that the JiTT strategy has indeed strengthened many areas of the instructor's pedagogical content knowledge. The JiTT activities allowed the instructor to assess easily the prior understandings of her students so that she could better address any misconceptions or gaps in their science knowledge. The in-class follow-up to each activity also forced the instructor to expand her understanding of instructional methodologies. Finally, the findings reveal that the JiTT strategy has indeed strengthened many areas of the instructor's pedagogical content knowledge.

The authors examined the effect of a new academic mentoring program on student academic integration, success and persistence. Specifically, the authors focused on the MIRES program (Mentoring for the Integration and Success of Science Students) aimed at preventing student dropout in math, science and technology. The MIRES program was implemented in two colleges in the Quebec City area. The results showed that participation in the MIRES programs had positive effects on motivation, career decision profile, college adjustment and academic success and persistence of students. The findings also revealed that the MIRES program had a greater impact on the perseverance of male, rather than female students.

The authors empirically examine the impact that students’ backgrounds, academic experiences, and attitudes have on their likelihood of selecting a STEM major in college. The findings revealed significant effects in relation to race, academic preparation, attitudes and dispositions toward math and science, college choice considerations, and postsecondary experiences.
