A comparative study of student attitude,learning and teaching practices in Pakistan and Britain

Good teaching is open to change and it involves constantly trying to find out what the effects of instruction are on learning, and modifying that instruction in the light of the evidence. Similarly, the ultimate outcome of instructional practice is effective student learning. Therefore, in this perspective, adequately meeting the varying needs of students is a major challenge for the modern education system in every country. As the title indicates, this paper attempts to explore students’ attitudes to studying and learning in order to help encourage greater engagement with quality learning. The study is based on primary data with regard to postgraduate education and learning in respective British and Pakistani education institutions—i.e. Moray House School of Education (Edinburgh University) and the Institute of Education and Research (University of the Punjab, Lahore). In the context of the collaboration of these two institutions, the paper focuses on the ways and means to enhance the system‐wide capacity for research‐based practice.     

金属支架药物涂层释放量的比较

临床应用中的PTCA技术,由于金属支架植入后对血管壁的损伤及异物的炎性反应,可引起内膜增生而导致血管内再狭窄.为解决这一难题,采用药物涂层支架进行控制和预防.通过不同的方式对金属支架表面进行药物涂层,并对药物释放量进行比较.     

时代歌手抒豪情--读杨若飞诗集《情海荡舟》

作为一名时代歌手,杨若飞的诗集《情海荡舟》题材广泛,形式多样。他的诗没有当今诗坛上颇为走俏的作者"自我表现"之作,有的只是对时代风貌的形象再现和对时代精神的充分表达。     

股部外伤致肠系膜下动脉栓塞1例

目的:分析股部刺伤与肠系膜动脉栓塞的关系,为防止临床上今后发生类似误诊提供参考;方法:结合临床误诊病例,联系基础医学理论进行分析并行开腹探查;结果:开腹探查证实该例股部刺伤患者急性腹痛乃因肠系膜下动脉的分支———乙状结肠动脉栓塞、乙状结肠坏死所致;结论:股部外伤,尤其是严重刺伤导致大血管破裂并脂肪组织严重损伤时可能引起其他器官脂肪栓塞。

教学范式转型是否可能——《教学设计的理论与模型：教学理论的新范式（第2卷）》解读

《教学设计的理论与模型：教学理论的新范式（第2卷）》在深入分析信息时代不同于工业时代特征的基础上,提出面向信息时代的教学范式,主张以定制化的、聚焦于学习的教学取代工业时代的标准化的、聚焦于分类的教学,变被动学习为主动学习,从教师的主动、控制和责任转变为分享的主动、控制和责任;从去境脉的学习转变为真实的、意义丰富的任务,以高层级的学习目标取代低层级的学习目标。新教学设计理论从多个不同的视角构建设计模型,并彰显教学方法的情境化考量和教学设计向＂用户设计者＂模式的转变,为在实践上进行教学范式转变提供了一种发展方向。     

Chicken or the egg: Longitudinal analysis of the causal dilemma between goal orientation,self-regulation and cognitive processing strategies in higher education

The aim of this study was to investigate the direction of the effect between goal orientation, self-regulation and deep processing strategies in order to understand the impact of these three constructs on students’ achievement. The participants were 110 freshmen from the engineering faculty at the Université catholique de Louvain in Belgium, who were followed during the first three years of their university studies. Data were analyzed through structural equation modeling. The main finding was that mastery goal orientation increased students’ subsequent deep processing which in turn enhanced subsequent self-regulation. Deep processing and self-regulation also appeared to be mutually influential from year 2 to year 3. The implications of our results for the understanding of the interplay between cognitive and motivational processes in higher education are discussed.     

Coronary arterial spasm in single right coronary artery

We presented a case of anomalous single-coronary artery detected incidentally during routine coronary angiography. A 32-year-old male Chinese patient presented with recurrent pre-syncope and six episodes of syncope. Coronary angiography and coronary-computed tomography (CT)-angiography performed by a dual-source computed tomography (DSCT) revealed that the patient had a single large right coronary artery. A moderately large branch originated from the proximal part of the single right coronary artery and extended to the left, passing the anterior to the pulmonary artery, and divided into the anterior descending artery branch and circumflex branch at the base of the left auricular appendage. The episodes of the syncope were suspected to be caused by coronary arterial spasm, so this patient was on a regimen of 30 mg of diltiazem every 6 h and had no recurrence of syncope during follow-up.     

食管颈段动脉供血体系的解剖学观察

为探讨食管颈段动脉供血体系构筑状况,以期为临床应用补充解剖学资料,利用成、幼尸体25具,红色乳胶灌注后剥离,对其分支吻合进行解剖学观察与系统分析;另取新鲜胎尸25具,其中墨汁灌注20具,钙钴法碱性磷酸酶染色5具后,组织切片,光学显微镜下观测。得出该段食管分支复杂、吻合丰富,各层均存在动脉网,粘膜下层动脉网最为丰富。
