    Does hands-on experience promote autonomous use of computer pods in science teaching ?
    Weller, Jacolyn ( 2009)
    We have ingrained into our teaching ideology that Information and Communication Technology (ICT) is an essential component of modern education. The computer pod was suggested in the early 2000's by the Department of Education, Employment and Training (DEET) as the means of providing students with access to ICT, but neither the method to harness nor how to direct innovation for best practice were indicated. A literature review by Hennessy and Osborne (2003) provided information on the available ICT tools for Science teaching and suggestions exist for the merits of using computer pods in Culbertson's (1999) reflections on nine studies and Owen's (2003) discussions of English teaching, but rarely was there a merger between the fields of computer pods and Science teaching. Professional development within a department where teachers create their own tasks provides a method of computer pod integration when slotting the tasks into the curriculum. This provides a future teaching document incorporating computer pod usage. The process of creating activities provides a training opportunity for developing accessible resources. The hands-on experience of Science teachers developing their own tasks for sharing aligns with self-help and effective resource management. Impediments exist for teachers in the form of time, equipment, availability, booking requirements, a philosophy that a 1:1 student: computer ratio is essential, comfort zone, student management and supervision. Incentives such as: students being keen, comfortable, suited to this learning style and capable users in this environment, who knowledge share with their teachers provide balance to the impediments. This artefact (the computer pod) is acknowledged as a rich component of learning, particularly in promoting group work, where students build their knowledge together. The results of interviewing five Year 8 Science teachers before and after the research year, where pro-noun analysis was used, generated the findings that Science teachers automatically expand their comfort zone in this environment and acquire the desire to experiment via a transition into the classroom with the activities they have specifically created. Individual teachers ventured further and used tasks developed by others for shared use, while others limited their involvement. This research provided a spectrum of responses, which exhibits variability of success and enhances the reliability of the results when presenting individuals as a range within a small sample. A broad picture even though it had a small focus group. The generated direction was an ownership component was generated in what an individual has created for themselves, which gives the incentive to test it out and simultaneously motivates autonomous integration into teaching strategies. This process has potential applications to others; whether it is other Science teachers, faculties within schools, individual teachers or more broadly, where ownership of the artefact enables the individual to confidently step forward with what becomes part of their skill acquisition and comfort zone.

    Distinguishing the science content taken by grade 12 students
    Cross, R. J. ( 1977)
    The population of grade 12 students in Australian secondary schools has been steadily increasing over the past two decades. For most of this period the percentage of students at this level choosing science-type courses has been decreasing, and recently the actual number taking physics and chemistry has declined in some states. This study aimed to find a set of variables that would maximize the prediction of grade 12 student science content. Emphasis was directed toward identification of science talented students not opting for high science content in grade 12, and, equally as important, those of low science ability who select predominantly science courses at this level. It was proposed that the variables could be measures of any area likely to be related to the criterion. For example, factors associated with the home, the school, and personal measures were all included. The variable set was then searched for that combination returning optimal criterion prediction. Attention was focussed on six main units of analysis viz males, males of higher science ability, males of lower science ability, females, females of higher science ability, females of lower science ability. The data in each unit was subjected to both discriminant (stepwise and direct) analysis and a process similar to a stepwise regression procedure called the Automatic Interaction Detector (AID). AID employs a branching process using variance analysis to subdivide the sample into subgroups which maximize dependent variable value prediction. The International Association for the Evaluation of Educational Achievement (IEA) conducted a series of tests on a stratified random sample of grade 12 students throughout Australia in 1970. The results, held at ACER, included measures of some 418 variables thirty four of which were selected for this investigation. Included in this group were the results of the four Commonwealth Secondary Scholarship Examination (CSSE) ability tests taken two years earlier. Analysis units were formed on the basis of sex and CSSE - Science score. The results indicate successful science content prediction is possible with the personal or internal variables of science interest, attitudes and abilities, consistently being of greatest importance. The participating external variables vary depending on the unit of analysis. The non-monotonic "State" and "Type of School" factors are predominant in AID analyses.
