Developing anti-discriminatory education: the impact of specialist training on practitioners and pupils

This article addresses the question as to whether training pre-school practitioners in an approach to anti-discriminatory education can impact on the developing attitudes of young children. This article attempts to analyse the effect of training practitioners in the delivery of an anti-discriminatory curriculum on the developing attitudes of the children they are teaching. This training was carried out with Leicestershire Foundation Stage settings.     

Isokinetic imbalance of hip muscles in soccer players with osteitis pubis

Abstract

In this study, we compared the isokinetic torques of hip flexors/extensors and abductors/adductors in soccer players suffering from osteitis pubis (OP), with normal soccer players. Twenty soccer male athletes with OP and 20 normal soccer athletes were included in this study. Peak torque/body weight (PT/BW) was recorded from hip flexor/extensor and abductor/adductor muscles during isokinetic concentric contraction modes at angular velocity of 2.1 rad · s^?1, for both groups. The results showed a significant difference between the normal and OP groups for hip flexors (P < 0.05). The normal group had significant, lower PT/BW value than the OP group for their hip flexors (P < 0.05). The hip flexor/extensor PT ratio of OP affected and non-affected limbs was significantly different from that of normal dominant and non-dominant limbs. There were no significant differences between the normal and OP groups for hip extensor, adductor and abductor muscles (P > 0.05). Regarding the hip adductor/abductor PT ratio, there was no significant difference between the normal and OP groups of athletes (P > 0.05). The OP group displayed increase in hip flexor strength that disturbed the hip flexor/extensor torque ratio of OP. Therefore, increasing the hip extensor strength should be part of rehabilitation programmes of patients with OP.     

A context-based integrative framework for e-government initiatives

The recent advances in the Internet technology have propelled the development of related applications in electronic communications and transactions, including electronic commerce and electronic government (e-government). There has been a proliferation of e-government initiatives worldwide undertaken under different forms of government, socioeconomic settings, and technological conditions. Nonetheless, the relationship between an e-government initiative and its context has not received adequate attention in the e-government literature. This paper provides an organizing framework that maps the core values (goals) of e-government to two fundamental factors; namely, the degree of e-government readiness and the level of democratization. The framework addresses the importance of the relationship between the context within which e-government initiatives are undertaken and the goals of those initiatives. From a conceptual perspective, this framework underscores the pivotal importance of the context of an e-government initiative in influencing the goals of this initiative. From a practical viewpoint, the framework provides a roadmap for policy makers to formulate policy goals of e-government initiatives commensurate with their respective environments.     

Search systems and their features: What college students use to find and save information

College students have often been surveyed about their general information seeking behaviors. However, little has been done to explore what specific system features they use to find and save information when they are working on their real-life tasks. In this study, 32 college students were invited to an information interaction lab for a session in which they recalled a recently finished task and worked on a to-be-finished task using a computer in the lab. They were asked to complete questionnaires regarding what systems they used to finish their tasks and what features were helpful for searching and for saving information. Results showed that college students rely more heavily on the Internet sources than on library sources, even for their course related work. The study identified fourteen categories of system features helpful for information search and eight categories helpful for information saving. The findings have implications for designing systems that will better help people accomplish their tasks.     

Implication de l'analyse de productions d'élèves dans la formation des maîtres du primaire

Several studies have shown that pre-service teachers enter their pre-service training with already formed conceptions pertaining to teaching and learning. Pre-service teachers are considered as epistemologically complex beings with varying postures they adopt according to differing contexts. This article looks at the meanings pre-service teachers attribute to pupil errors and how these meanings evolved over the course of a 15 week course in mathematics education. Pre-service teachers were interviewed at two intervals during their first semester: at mid session and at the end. First, we identified the various kinds of analyses they brought to bear upon pupil errors as well as the interventions they suggested to rectify these errors. Then, we conducted a statistical analysis of the changes in the type of interventions suggested. Four trend indicators were created to help understand these changes. When analysing pupil's errors, pre-service teachers identified specific conceptual elements without situating them within a global context. This led to piecemeal interventions about how pupils ought to correct their errors. In conclusion, pre-service teachers' appear to base their analyses of pupils's errors upon an epistemological positioning ween title ‘former-pupil stance‘. This stance seems to create a resistance to changing their conceptions regarding the teaching and learning of mathematics.

Contrasting perceptions of an innovation in engineering education

There has been considerable criticism about the effectiveness and appropriateness of degree courses in engineering over recent years. In part the criticism have related to inadequate preparation for the profession and in part to the traditional methods of teaching. As a reaction to these criticism, attempts were made at one particular technological institution to change the way in which parts of one particular course were taught. The first problem was created by a relatively high failure rate in examinations. In addition, it was felt that problem-solving was an important skill which had been inadequately taught through the conventional lecture course. Previous research had suggested that audiotapes on which students could work and take notes at their own pace might improve the examination results and help with problem-solving skills relevant to the professional engineer. The innovator found evidence for the success of the innovation in terms of a decreased failure rate and his own satisfaction with the changed emphasis in his part of the degree course. However, an independent evaluation based on interviews and observation found that other members of staff, and the students, all held different perceptions of the effectiveness of the innovation. The contrasting perceptions reflected, in part, the extent to which the staff had been involved with the innovation, and the purposes of the students in using the innovative materials and techniques. The study points up difficulties in introducing an innovation into higher education and shows the importance of the very different perceptions held by those who come into contact with the innovation. Implications for understanding the impact of learning environments on student learning, and for the introduction of innovations, are discussed.     

A data-mining approach to biomarker identification from protein profiles using discrete stationary wavelet transform

Objective: To develop a new bioinformatic tool based on a data-mining approach for extraction of the most infor-mative proteins that could be used to fred the potential biomarkers for the detection of cancer. Methods: Two independent datasets from serum samples of 253 ovarian cancer and 167 breast cancer patients were used. The samples were examined by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS). The datasets were used to extract the informative proteins using a data-mining method in the discrete stationary wavelet transform domain. As a dimensionality re-duction procedure, the hard threshoiding method was applied to reduce the number of wavelet coefficients. Also, a distance measure was used to select the most discriminative coefficients. To find the potential biomarkers using the selected wavelet coefficients, we applied the inverse discrete stationary wavelet transform combined with a two-sided t-test. Results: From the ovarian cancer dataset, a set of five proteins were detected as potential biomarkers that could be used to identify the cancer patients from the healthy cases with accuracy, sensitivity, and specificity of 100%. Also, from the breast cancer dataset, a set of eight proteins were found as the potential biomarkers that could separate the healthy cases from the cancer patients with accuracy of 98.26%, sensitivity of 100%, and specificity of 95.6%. Conclusion: The results have shown that the new bioinformatic tool can be used in combination with the high-throughput proteomic data such as SELDI-TOF MS to find the potential biomarkers with high discriminative power.     

The effect of content representation design principles on users’ intuitive beliefs and use of e-learning systems

A model is proposed to assess the effect of different content representation design principles on learners’ intuitive beliefs about using e-learning. We hypothesized that the impact of the representation of course contents is mediated by the design principles of alignment, quantity, clarity, simplicity, and affordance, which influence the learner’s intuitive beliefs about using e-learning systems. The model was empirically validated using data collected from a survey administered to university students. This study demonstrates that these design principles are essential predictors of learners’ intuitive beliefs, which in turn directly influence their decisions about using e-learning systems. The findings provide system designers with quasi-quantitative managerial insights into how to motivate users to continue using e-learning systems.     

The alignment between the fourth grade Lebanese science curriculum and classroom assessments

The purpose of this study was to investigate the alignment between the fourth-grade summative classroom assessments and the ‘Matter and Energy’ unit in the Lebanese science curriculum using: content and cognitive levels. Summative assessments were collected from a sample of 17 schools. The alignment between the classroom assessments and the Lebanese science curriculum were examined using three instruments: Curriculum Coding Sheet, Items Coding Sheet, and Item Analysis Sheet. The curricular learning objectives were used for matching the test items to the learning objectives in terms of content. Findings showed moderate content alignment; further analysis revealed that public schools had higher content alignment, and they covered a wider range of topics. In terms of cognitive level, there was a low alignment between the assessments collected and the curriculum; however, there were items that had higher cognitive level. Recommendations for curriculum developers and future research are discussed in light of these findings.
