This paper examines Science Practical Assessment (SPA) in the Singaporean classroom. In contrast to teacher-centric task setting and evaluation, this paper reports findings from a study where a class of students were involved in their own assessments mediated by digital video. Students were recorded during practical work and were then asked to review and edit the footage. Next, they evaluated their own and their classmates’ practical skills. These evaluations, scaffolded with a template and facilitated by the teacher, aimed to give the students a voice in presenting what they thought made ‘good’ science practical skills and practices in the laboratory. They also served as a platform for peer learning and provided a means for the students to be involved in discussing science and science practical skills. Results of this study reveal that students’ awareness of acceptable laboratory practices is enhanced through this innovative method of evaluating science practical work.

This paper presents initial findings from an ongoing ethnographic study carried out among Normal Technical students from a secondary one class in a typical neighbourhood school since the start of the 2005 school year. Assertions about the social organization of the classroom and how this relates to teacherstudent interaction provide us a window into some of the classroom management issues and conditions for learning that emerge in the N(T) classroom. Specifically, this paper focuses on the perspectives of the students in the program. The ‘silent’ lot, although a minority, is a group of students that needs to be helped so that they can become productive and contributing individuals to the society at large. They need to be given equal learning opportunities to enable them to maximize their learning potential.

Scardamalia (2002) discussed the knowledge building notion as one which is built on social cognitive principles of learning. She proposed 12 principles focusing on collaborative knowing among students gearing toward building a community of learners in classrooms. However, how teachers become the key mediator for fostering knowledge building in classrooms is not fully explored. This study aims to contribute to the knowledge building research in terms of teacher professional development. Set in Singapore, where the dominant pedagogy is teacher centred and routinised (Luke, Cazden, Lin & Freebody 2005), this paper examines the journey taken by two biology teachers trying to reform their classrooms by incorporating knowledge building principles. In one of our email exchanges with a teacher, she was exasperated with her attempt to bring knowledge building into her classroom. After a few sessions, she exclaimed “But I have not started teaching!” This prompted us to seek answers to the research question “What are the factors that will impact knowledge building efforts in a Singapore science classroom?” Interviews and transcript analysis of classroom lessons are used as data and interpretive methods of data analysis are used in this paper. The beliefs of the teachers are elicited through a semi-structured interview which takes the form of a post-lesson dialogue in this paper. The results of this study revealed three key areas of concern in adopting knowledge building principles, namely, renegotiation of institutional authority, changing beliefs about teaching, and learning and building students’ capacity for epistemic agency. In order for teachers to transform their practices in the classroom, there needs to be a structured and concerted understanding of these factors.

This paper examines the use video playback technology coupled with the use of blogs and wikis in developing the reflection skills of 22 pre-service science teachers. Specifically, this paper illumines what pre-service teachers notice and subsequently make sense of teaching as they watch video segments of teaching taking place. It is found that pre-service science teachers primarily took notice of teaching skills and then used that as a primer to reflect upon classroom management, students’ learning need, the learning environment and how teachers plan their lesson. The use of videos and reflective blogs offers a systematic and structured way from evidence-based reflection of teaching for pre-service teachers.

This paper tracks the learning experiences in science of three students using Knowledge Forum. We examine the interaction process, in particular the seeking patterns that result as the three students explore and build the knowledge of convection current. Using micro-analysis of contribution on Knowledge Forum and principles of analysis of electronic interaction and discourse proposed by Zhu (1989), this paper analyses the forms of participation a student can assume, focusing mainly on the different forms in which students seek information as they navigate through the sea of information posted online. Using a grounded approach, we characterize two different ways in which students seek for information in an online environment, which we labeled as interpersonal seeking and collaborative seeking. We believe that the seeking behavior, albeit subtle, is instrumental in directing learning and directing the courses of ‘discussion’ and the quality of the knowledge that is built.

Research on argumentation has increased our understanding of knowledge construction, group learning, and scaffolding structures in CSCL although analyses of argumentation pose many difficulties. This could be due to the many theoretical positions that can be taken when approaching discourse data. In this paper, we use three popular analytic methods (interactional, content-specific, and linguistic) to compare the same fragment of scientific argumentation by Grade 4 children in Singapore. We show the complementary emphases and strengths of each disciplinary position as well as their weaknesses. The results imply that analytic methods arising from different disciplinary positions can potentially broaden our overall understanding of using argumentation in CSCL.

One of the goals of inquiry-based teaching and learning of science is for students to learn the processes of inquiry and to apply these processes in new situations to construct new knowledge for themselves. Very often, students who are exposed to inquiry activities encounter conceptual conflicts that do not align with their pre-conceived ideas. How these conflicts are resolved provide different types of learning experiences for the learners. Interaction talk during hands-on science inquiry activities provides a good source of information on how students deal with conceptual conflicts and, in particular, how they apply inquiry skills to resolve these conflicts. The analysis of talk in interaction amongst a group of six grade five students in a Singapore school has surfaced at least three ways whereby students construct and shape their learning in an inquiry-based science activity through the ways they deal with conceptual conflicts: (a) domineering voices in a group can prematurely curtail alternative ideas and concepts in dealing with a conceptual conflict; (b) a peer expert in a group can scaffold learning for a student facing a conceptual conflict; and (c) learners draw on inquiry skills to resolve cognitive conflicts arising from anomalous results or behaviours during hands-on investigations.

This paper reports an empirical study on the use of a teacher noticing approach to investigate how two teachers managed students’ classroom behaviours. We examined the integration of data from an eye-tracking device and video cameras, focusing on what the teachers paid attention to in classrooms with their corresponding managing practices. Our findings show that the experienced teacher was able to advise her students calmly and smoothly resume the lesson to preserve the welcoming environment for the students. The novice teachers constantly scanned for misbehaved students and at times used strong words and a stern voice that betrayed her emotions. The awkward silence of the class ensued, suggesting a break in the flow of the instruction.
