ItemWhat are the blockers/facilitators for a science coordinator to integrate datalogging into science teaching( 2002)This project investigates a coeducational Secondary College Science Department that decided to introduce datalogging as a teaching tool. Datalogging is the electronic recording of data during an experiment using sensor probes. Decisions concerning the introduction of datalogging involved the science teaching staff, the laboratory technician and the Science Coordinator, all stakeholders in this process. This investigation was developed with the hindsight of a Literature Review, which provided the advice of others' experiences and catalogues the introduction in a case study format. Action research strategies were invoked through a series of focus interview questions, which provide a 'snap-shot' of the perceptions. From here a collaborative Change Management strategy of introducing datalogging into science teaching was produced. The factors that inhibited or prevented the use of datalogging in teaching were considered to be 'blockers'. Through interview questions the teachers and the laboratory technician were asked what they felt blocked their use of datalogging. The time required to become comfortable, familiar, confident and experiment with the equipment arose as the major concern for all teachers prior to using datalogging in science teaching, while the laboratory technician had more physical impediments. The technology capable participants did not encounter major hindrances. There was a constant limitation of equipment due to its expense, which was a factor accepted by all and where innovation in teaching style was required to overcome this impediment. However, all felt that visual 'memory-jogs' of the availability and uses of the equipment would encourage use. The factors that contributed to datalogging use were the 'facilitators'. These included a well rounded, informative and ongoing professional development strategy involving all staff members sharing knowledge combined with a laboratory technician who was conversant with the equipment, constantly promoting and encouraging usage and aiding the process. Throughout the project constant active problem solving emerged as a strategy by teachers whenever a 'blocker' was suggested. The advantage of collegial sharing through professional development was also recognised by staff and thought to integrate well when developing technology as a teaching tool. The process overall was time intensive due to lack of time in the working week when people are at different stages in embracing change and technology. Consequently whatever was learnt by individuals was regarded as worth sharing professionally.

ItemHow may the use of an abstract picture language affect student learning of energy and change( 2002)The teaching of `Energy' as a topic in school science has often been found in the professional and research literature to be incoherent and scientifically inconsistent. Boohan and Ogborn's `Energy and change' booklets are an attempt to outline a new way for teachers in junior science classes to talk about processes that drive everyday changes from the weather to a car moving. They have sought, around the central idea that change is caused by differences, to use easy language and find coherent ways to describe thermodynamic ideas. They developed a set of abstract pictures to make these ideas intelligible. In this phenomenological classroom-based study the experiences afforded two Year 8 classes and their teachers in the same school in Melbourne by the use of Boohan and Ogborn's abstract picture language are investigated. One teacher took a didactic/empirical approach. He taught from his architectonic conceptual map of energy and followed the standard textbook development of forms of energy punctuated by the recommended experiments and teacher demonstrations to illustrate various changes in form. The abstract pictures were used principally in discussion as summative and interrogative tools towards a clarification of the teacher's conceptual overview. The other teacher took a co-constructive experiential approach. She did not use a class text. The Boohan and Ogborn materials were used as gestural tools in the sense of presenting the gist of the embodied understanding- purposes and meaning- of teacher and students. There were some teacher demonstrations but no practical work. The picture language icons functioned as mediating tools in class conversations towards a perception not that certain predefined teacher concepts had been attained but rather individuals had attained confidence to go on from that juncture. The students' responses to the picture language, in class interaction and group interviews, revealed major similarities across these teaching approaches. Many saw the abstract picture language to be a powerful and economic representational or iconic device that afforded them a means of engaging their own embodied socio-cultural understanding of energy and change phenomena. Some were confused by the purpose and meaning inscribed in the icons. Both teachers felt professionally challenged in the employment of the materials and only partly satisfied by their different enactments. Both were engaged and curious about the intellectual, sensational and aesthetic dimensions of their and their students' experience.
