Professional learning and development of two groups of pre-service teachers with different scientific knowledge bases and different teaching training in the course of their studies
This research study evaluated the professional development of two groups of pre-service biology teachers during a year-long biology didactics course in two different academic institutions. Verbal and qualitative analyses of lesson transcripts were employed to characterize explicit knowledge, while content and cluster analyses of the repertory grid technique were employed to characterize tacit knowledge. The group of pre-service teachers with lower content knowledge (CK) and more teaching experience during their training was concerned with student- and teacher-centered practices. The group with higher CK and less teaching experience was concerned with high-order thinking skills and the knowledge gap between themselves and their students.

Educative Mentoring: How a Mentor Supported a Preservice Biology Teacher’s Pedagogical Content Knowledge Development
The purpose of this study is to describe the strategies used by a highly regarded, secondary biology mentor teacher to foster a preservice biology teacher’s pedagogical content knowledge (PCK). In this study, the mentoring was exclusively focused on beliefs about effective science teaching and how students’ learn science. The mentor teacher helped preservice teacher understand why he should teach in particular ways. The mentor also helped the mentee develop his topic-specific knowledge of students’ understanding of science by discussing common misconceptions revealed in students’ conversations and examination responses. She modeled ways for the mentee to access students’ misconceptions.

The Impact of a Novel Curriculum on Secondary Biology Teachers’ Dispositions Toward Using Authentic Data and Media in Their Human Impact and Ecology Lessons
The study examines how implementation of a real-world data and media-centered human impact curriculum influenced teacher dispositions toward using data and media in their ecology and human impact lesson plans. It explores how integration of these elements shapes teachers’ lesson plans. The findings show that this curriculum implementation positively affected teachers’ dispositions to use data analysis and media about scientific research to explain how people impact ecological function. Furthermore prior to the curriculum implementation, many teacher lesson plans focused on the general theme that people harm the environment. The curriculum gave teachers cases of data and media examples that helped them specify the particular ways people cause ecological harm.

This study had two objectives: (1) to analyse the relationship between prospective primary teachers’ recall of emotions in school science classes as pupils themselves and their expectations of emotion as future teachers and (2) to analyse the relationship between their self-efficacy and the emotions that they expect to experience as future science teachers, differentiating between the content of the ‘nature sciences’ and that of the ‘hard sciences’. The results show that prospective primary teachers have completely different emotions about their future teaching according to whether the content is related to the nature sciences or the hard sciences. Positive emotions predominate for the nature sciences, while for the hard sciences the predominant emotions are all negative.

The purpose of this study is to describe and understand prospective science teachers’ knowledge development. This is a longitudinal, multiple case study of four prospective biology teachers’ PCK development during a post-baccalaureate teacher education program. The authors learned that as prospective teachers gained more knowledge and experience, the interaction that develops between teachers’ knowledge of learners and their knowledge of instructional sequences becomes more integrated. In addition, the findings demonstrate a strong relationship exists between science teaching orientations and knowledge of learners and instructional sequences.

Examining Teachers’ Instructional Moves Aimed at Developing Students’ Ideas and Questions in Learner-Centered Science Classrooms
In this study, the authors examined teachers’ instructional moves to elicit and develop students’ ideas and questions as they orchestrated discourse with their fifth grade students during a learner-centered environmental biology unit. The authors present three contrasting cases of teachers to highlight evidence that shows teachers’ differing strategies for eliciting students’ ideas and questions, and for developing their ideas, questions and questioning skills. The authors found that teachers could readily elicit ideas and questions but experienced challenges in helping students develop them.

Pre-service Biology Teachers’ Perceptions on the Instruction of Socio-scientific Issues in the Curriculum
This paper represents a preliminary attempt to address the role of teachers in supporting students’ learning on socio-scientific issues by characterising pre-service biology teachers’ perceptions and adaptation of curriculum and identifying factors that serve to mediate this process. The results indicated that the teacher candidates perceived a need to address SSI positively. Pre-service teachers had moderate personal teaching efficacy beliefs related to teaching about SSI.

The Secrets of Successful Veteran Biology Teachers: Metaphors of Evolution, Regeneration, and Adaptation
Voices of veteran junior high and high school biology teachers are seldom heard. The purposes of this study are (1) to enhance the understanding of personal and contextual factors influencing veteran teachers' career choices; (2) to create veteran teachers profiles; (3) to examine their survival strategies; and (4) to find out what the education system needs to do to enjoy successful their possible contributions. The findings revealed three types of survival strategies: (1) adapting, transforming teachers; (2) non-transforming teachers; and (3) regenerated teachers.

Developing Biology Lessons Aimed at Teaching for Understanding: A Domain-specific Heuristic for Student Teachers
Teaching for understanding requires teachers to organize thought-demanding activities which continually challenge students to apply and extend their prior knowledge. Research shows that student teachers often are unable to develop lessons in teaching for understanding. The authors explored how a domain-specific heuristic can assist student biology teachers in developing problem-posing lessons according to teaching for understanding. In general, the heuristic appeared helpful to most student teachers for designing problem-posing lessons satisfactory according to the criteria.

The purpose of the study is to compare the outcomes of reflecting on difficult problematic experiences with those of reflecting on positive experiences. The authors focused on three outcome areas: the content of teachers' resolutions after reflecting because decisions need to be productive, their motivation to act on their decision because teachers need to implement their decision because teachers need to implement their resolutions, and the emotions they have during the process of reflection because emotions are very influential to thinking and learning. In an exploratory study, 16 student biology teachers were asked to reflect on two problematic and two positive teaching experiences and to take notes during the reflection process.
