The classmate PC 1:1 eLearning project in Australia

Increasingly on the agendas of governments and educational leaders is an impetus to increase the number of computing devices in schools across Australia. There is much expected, promised and hoped for in developing 1:1 eLearning pedagogies, or ubiquitous approaches in ICTs. In 2008, the Intel Classmate PC 1:1 eLearning Project investigated the effects on classroom practices which arose from the provision of low-cost mobile learning devices for each student to use in a collaborative learning environment. The overall goal of the research was to provide evidence and understanding about the impact of 1:1 eLearning on student/teacher and student/student interactions, pedagogical and curriculum practices and student learning. This presentation draws from six primary school case studies, across three States of Australia. Significant successes and challenges were experienced across the diverse sites of these studies. Through these schools’ participation in this pilot study, five key factors have been identified as contributing to, or hindering the adoption and implementation of the devices. These included: ICT infrastructure, connectivity and hardware; Teacher attributes; Pedagogical and curriculum approaches; Teacher professional knowledge, and; School leadership.

Polycarbonate (PC) membrane fouling by protein and sodium alginate

This data was obtained from an experiment, where polycarbonate (PC) membranes were used to filter two types of organic foulants, including protein and sodium alginate, from suspension in a dead-end filtration cell. These model foulants were stained with fluorescent dyes before filtration. Consequently, a stack of images were captured from the fouling layers on the PC membrane surface using confocal laser scanning microscope (CLSM). This data collection contains 105 2D images of polycarbonate (PC) membranes fouling layer. This data collection would be useful to investigate membrane fouling mechanism by membrane materials researchers and water researchers.

Evaluating backwashing efficiency of polycarbonate (PC) membrane fouled by protein and sodium alginate

This collection is the result of an investigation into the backwashing efficiency of polycarbonate (PC) membrane fouled by two types of organic foulants, protein and sodium alginate. In this experiement, polycarbonate (PC) membrane was used to filter those organic foulants from suspensions in a dead-end stirred cell. The organic foulants were stained with fluorescent dyes before filtration. After filtration, the PC membrane was backwashed. Consequently, a stack of images were captured from the fouling layers on the PC membrane surface using confocal laser scanning microscope (CLSM) and its associated image acquisition software. It contains image data of polycarbonate (PC) membranes' fouling layer when two types of organic foulants (protein and sodium alginate) are present. By comparing with the same membrane without backwashing, the efficiency of backwashing was computed. This data collection would be useful to researchers evaluating the backwashing efficiency of PC membrane in order to optimize frequency and operational conditions of backwashing by membrane materials researchers and by water..

The Tablet PC: A Complete Teaching Studio

The Tablet PC is a flexible teaching tool. It can be used to increase the lecturer’s productivity in note taking and in assignment marking. It can be used in the lecture room with increased interaction. With a few minor accessories it can be used to record all aspects of a lecture or presentation. It can also be used to record short topic segments that can be used as references or summaries by students. Containing the abilities of both a tablet device with multi touch, a pen interface for accurate drawing and handwriting and with the power of a full PC, it is a complete teaching studio.

Exploring tablet PC lectures: lecturer experiences and student perceptions in biomedicine

Lecturers using tablet PCs with specialised pens can utilise real-time changes in lecture delivery via digital inking. We investigated student perceptions and lecturer experiences of tablet PC lectures in large-enrolment biomedicine subjects. Lecturers used PowerPoint or Classroom Presenter software for lecture preparation and in-lecture pen-based inking. Using surveys and lecturer interviews, students and lecturers were asked to reflect on their tablet PC lectures in comparison to non-tablet lectures that used prepared images and a laser pointer. Quantitative survey responses suggested that students felt that the tablet lectures were more interesting, that they were more capable of keeping up with the lecturer, and they enhanced their understanding of the lecture content. Qualitative analysis of written comments indicated that students appreciated the real-time writing and drawings, particularly because these were visible on lecture recordings. When reflecting on their non-tablet lectures, most lecturers used the pen-based writing, drawing and highlighting tablet functions and reduced lecture pace and content for their tablet lectures. Long-term tablet use led to lecturers making more use of digital inking, with less use of prepared images. Our results support the idea that tablet PC-supported lectures are conducive to improved management of cognitive load via reduced lecture pace and content.

Developing a primary care patient measure of safety (PC PMOS): a modified Delphi process and face validity testing

BACKGROUND: Patients are a valuable source of information about ways to prevent harm in primary care and are in a unique position to provide feedback about the factors that contribute to safety incidents. Unlike in the hospital setting, there are currently no tools that allow the systematic capture of this information from patients. The aim of this study was to develop a quantitative primary care patient measure of safety (PC PMOS). METHODS: A two-stage approach was undertaken to develop questionnaire domains and items. Stage 1 involved a modified Delphi process. An expert panel reached consensus on domains and items based on three sources of information (validated hospital PMOS, previous research conducted by our study team and literature on threats to patient safety). Stage 2 involved testing the face validity of the questionnaire developed during stage 1 with patients and primary care staff using the 'think aloud' method. Following this process, the questionnaire was revised accordingly. RESULTS: The PC PMOS was received positively by both patients and staff during face validity testing. Barriers to completion included the length, relevance and clarity of questions. The final PC PMOS consisted of 50 items across 15 domains. The contributory factors to safety incidents centred on communication, access to care, patient-related factors, organisation and care planning, task performance and information flow. DISCUSSION: This is the first tool specifically designed for primary care settings, which allows patients to provide feedback about factors contributing to potential safety incidents. The PC PMOS provides a way for primary care organisations to learn about safety from the patient perspective and make service improvements with the aim of reducing harm in this setting. Future research will explore the reliability and construct validity of the PC PMOS.
