Abstract:
This paper reports on a study of students' conceptual sensemaking with science diagrams within a computer-based learning environment aimed at supporting collaborative learning. Through the microanalysis of students' interactions in a project about energy and heat transfer, we demonstrate "how" representations become productive social and cognitive resources in the students' conceptual sensemaking. Taking a socio-cultural approach, the study aims to contribute on two levels. First, by providing insight into the interactional processes in which students encounter a particular type of representation: science diagrams. Second, the study aims to demonstrate that an important aspect of students' encounters with science representations concerns making sense of how to respond to institutional norms and social practices embedded within the context of schooling. The findings demonstrate how the science diagrams become productive social and individual resources for the students by slowing down the students' conceptual sensemaking processes and by opening up a space for the interpretation and negotiation of scientific concepts, as well as of the representations themselves. The study also shows the challenges involved when students move from oral to written accounts in their inquiries.

Abstract:
The value of mangroves and mangrove ecosystems has not always been recognized. In fact, mangroves were historically regarded largely as wastelands with little or no value. Over time, humans began to recognize the multiple ways in which they could be used, particularly through development, making the mangrove ecosystem vulnerable to destruction and depletion, a globally alarming issue. Mangrove depletion is presented here as socioscientific issue cases with activities designed to promote and strengthen ocean literacy. Through these activities, students can explore scientific concepts relating to mangrove ecosystems while fostering moral and ethical reasoning to determine what is affected and valued, and who shares responsibility.

Abstract:
In the following article, Dr. Seuss's children's books are creatively integrated with science activities through the creation of take-home activity kits. The kits provide families an opportunity to read at home while connecting the enjoyable experience to science content and skill development through associated activities. The kits should be constructed using easy-reading books and aligned to developmentally appropriate academic science standards. Most importantly, they should be designed in a manner so that all family members are participants rather than expecting the adults to teach the expected outcomes. The activity kits can be completed as stand-alone experiences for interested students, used by students who are ready for an additional challenge, or adapted for an entire classroom of students as part of a teacher's normal curriculum. (Contains 1 table, 6 figures, and 3 resources.)

Abstract:
In the present study, we have explored an aspect of teachers' perceptions of biology diagrams. The research was performed in Turkey. The data were gathered from 50 (25 female, 25 male) teachers of primary and secondary schools and 34 (18 female, 16 male) academic staff of different universities in Turkey. Some of the participants are science specialists and the others are non-science specialists. The data were collected in 2012. A qualitative approach was adopted. The data were collected in three steps. First, biology diagrams from the internet were collected and some (12) biology diagrams were chosen by the researchers. In the second step, these selected diagrams were shown to the teachers and academic staff. In this step the participants were asked to think aloud about what they saw when they looked at the diagrams. In the third step, semi-structured interviews were carried out in order to examine further the thoughts of the participants about what they saw in these diagrams. In our study we found there were no significant differences in responses between the science and non-science specialist teachers and academic staff. We conclude that it may be helpful to train teachers in the processes of constructing and reading diagrams. (Contains 7 tables and 7 figures.)

Abstract:
This article describes how inquiry teaching can be directed towards specific content learning goals while allowing for student exploration and validation of hypotheses. Drawing from the Theory of Didactical Situations, the concepts of "milieu" and "validation" are illustrated through two sample biology lessons designed to engage and challenge students in scientific inquiry. The article proposes that these concepts may help teachers design rich learning environments wherein students may pose and test their hypotheses against scientific data. This may in turn help overcome several challenges relating to open-inquiry teaching. Such challenges include divergent student learning outcome or time issues and practical constraints of facilitating inquiry in large classes. The presented approach can help teachers design directed inquiry teaching sequences that can lead to more frequent use of inquiry in teaching thanks to the efficacy of such designs.

Abstract:
The aim of this exploratory, longitudinal study was to describe an overall picture of how perceptions of the teacher role and attitudes toward science and science teaching develop and interact during preschool teacher education, and how this in turn influences behavior when students are engaged in teaching science. Sixty-five students enrolled in a preschool teacher education program at a Swedish university were followed throughout their teacher education. The study used a phenomenographic approach within a theoretical framework of sociocultural and situated learning perspective. Questionnaires with open and closed questions were combined with interviews. The results show that in spite of growing competence and confidence, many of the students still found science activities to be awkward in preschool, mainly due to a wish to protect the children from school culture. The results have implications for teacher education and the preschool community, showing a need to problematize the purpose of teaching science in preschool and the meaning of pedagogical content knowledge in this context. (Contains 1 figure and 4 tables.)

Abstract:
This study investigated a sample of isiXhosa mother tongue-speaking science teachers', their pupils', and adult local community members' awareness of Xhosa indigenous knowledge. It also investigated what aspects of this knowledge they value and think should and could be integrated into the school science curriculum and their reasons for suggesting that it should (or should not) be incorporated. The participating teachers voluntarily completed an open-ended questionnaire. On completion, they were given the task of administering the questionnaire to at least 1 of their pupils and 1 community member who they believed could contribute ideas about indigenous knowledge that might relate to science education. Interviews were held with a small sample of teachers and community members. The data generated suggest that there is a shared awareness of indigenous knowledge across the respondents (teachers, pupils, and community members). The reasons given for including indigenous knowledge in the school curriculum related mainly to the realm of recognition (social justice and cultural sensitivity), and there was also little evidence that the respondents were aware of current understandings underpinning the demarcation of science and indigenous knowledge as disciplines.
