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.

This case study examined the experiences of a group of high school science teachers participating in a unique professional development method involving an argue-to-learn intervention. Findings indicate that participant groups were more likely to use the Web to find unique evidence than to they were to use the provided materials.

Mind the Gap: Looking for Evidence-Based Practice of Science Literacy for All in Science Teaching Journals
The authors examined whether science teaching journals’ recommendations are anchored to high-quality evidence. The authors found that (a) most National Science Teacher Association journals’ science literacy recommendations have weak or no evidence base and (b) those with evidence reference teaching journals, teacher resource books, and literacy education more often than science education research.

The authors explored pupils’ understanding of chemical change. This change was investigated in relation to two cognitive variables: logical thinking and field-dependence/field-independence. The participants were 99 sixth-grade elementary school pupils, which were involved in two different tasks related to combustion. The findings provide empirical evidence that the above individual differences have an effect on pupils’ understanding the phenomenon of chemical change at that critical age.

The Excitement and Wonder of Teaching Science: What Pre-service Teachers Learn from Facilitating Family Science Night Centers
The author describes how pre-service teachers facilitated stations at a family science night as a context to learn to identify, assess, and use children’s science ideas. The pre-service teachers in this study experienced success at teaching science and developed understandings about children’s science ideas.
