Curtin University operates a computer‐managed learning package that gives students the option of undertaking a practice test before the unit assessment. This test is designed predominantly to contribute to student learning and, as such, is considered formative. 417 students took advantage of the optional practice test (PT) and their marks on the unit assessments were compared with those students (N = 197) who opted not to take the practice test (non‐PT). There was a significant improvement in the mean mark of the PT group from the practice test to the first unit test (p < 0.001). The PT group also significantly out performed the non‐PT group. They were significantly better on both unit tests although only the first unit test was preceded by a practice test (p< 0.001). This was despite apparently weaker students opting to sit the practice test. Students who performed the practice test improved their mark on the assessment tests and performed better on these tests than those students who did not do the practice test. Based on these data, practice tests should be offered before all unit assessments despite the implications for departmental resources. 相似文献

England has experienced recent growth in the prevalence of private tutoring (PT). The qualitative study reported in this article aims to explore the perceptions of 14 Year 6 pupils and their teachers from three state-maintained primary schools in East Kent on PT participation and its impact on grammar school admissions. Data were collected through individual and focus group interviews and pupils' drawings. The data revealed that teachers were not totally aware of the scale of PT in their classes and ascribed PT merely to parental decision to prepare their child to pass the 11-plus, grammar school entrance test. However, some pupils indicated that they shared in the decision to have PT, affirming that it was not only for 11-plus test familiarisation and practice. PT also contributed to greater pupil confidence, involvement and enthusiasm for learning, together with improvement in social interactive skills (i.e. intangible benefits). Both teachers and pupils also explained the disadvantages of PT, including the psychological and financial burdens on the whole family and changing the playing field level. Teachers proposed some solutions to help Year 6 pupils without PT. From this qualitative study, pedagogical implications as well as areas for ongoing research are suggested. 相似文献

Quality of healthcare delivery is dependent on collaboration between professional disciplines. Integrating opportunities for interprofessional learning in health science education programs prepares future clinicians to function as effective members of a multi‐disciplinary care team. This study aimed to create a modified team‐based learning (TBL) environment utilizing ultrasound technology during an interprofessional learning activity to enhance musculoskeletal anatomy knowledge of first year medical (MD) and physical therapy (PT) students. An ultrasound demonstration of structures of the upper limb was incorporated into the gross anatomy courses for first‐year MD (n = 53) and PT (n = 28) students. Immediately before the learning experience, all students took an individual readiness assurance test (iRAT) based on clinical concepts regarding the assigned study material. Students observed while a physical medicine and rehabilitation physician demonstrated the use of ultrasound as a diagnostic and procedural tool for the shoulder and elbow. Following the demonstration, students worked within interprofessional teams (n = 14 teams, 5–6 students per team) to review the related anatomy on dissected specimens. At the end of the session, students worked within interprofessional teams to complete a collaborative clinical case‐based multiple choice post‐test. Team scores were compared to the mean individual score within each team with the Wilcoxon signed‐rank test. Students scored higher on the collaborative post‐test (95.2 ±10.2%) than on the iRAT (66.1 ± 13.9% for MD students and 76.2 ±14.2% for PT students, P < 0.0001). Results suggest that this interprofessional team activity facilitated an improved understanding and clinical application of anatomy.

INTRODUCTION Multiphase flow is normal phenomena in indus- try. In past decades, investigations on multiphase flow measurement were mostly focused on the proc- ess tomography (PT) technology (Li, 2000), including electrical capacitance PT, electrical resistance PT, electromagnetism PT, X-ray PT, Ultrasonic PT and so on. Unfortunately, these PT technologies are not good enough to meet industrial requirements because of the image reconstruction quality, cost or safety. In recent year… 相似文献

Private tutoring (PT) is a widespread educational phenomenon that blurs the conceptual boundaries of public and private education and can affect the formal school system and teachers’ work. This study examined whether participation in PT and the estimation of private tutors’ contributions are related to pupils’ attitudes towards teachers’ effectiveness. Based on a questionnaire administered to all pupils (n = 855) from Grades 7 to 10 from one secondary school located in an affluent area at the centre of Israel (respondence rate, 83.2%), it was found that overall, there were few differences in students’ attitudes between participants in PT compared to those who did not participate in PT. However, among those who participate in PT, their attitudes towards school teachers are related to the distinction between the academic and social-affective contribution of private tutors. When PT is related to academic spheres, it enhances positive attitudes towards school teachers and when PT is related to socio-affective aspects, it increases criticism. The findings highlight the complex interactions of PT with mainstream education and emphasise the challenges school teachers face in view of the trend for more personalised learning approaches. 相似文献
