Analysis of the effects of the combination of PBL and multimedia network teaching model in the preclinical course of image diagnostics

目的：探讨PBL联合网络教学在《影像诊断学》见习中的应用效果。方法选择广州医科大学医学影像学本科专业2011、2012级共126名学生为教学对象，在《影像诊断学》见习课中采用PBL联合多媒体网络教学。课后实施问卷调查，并让学生撰写学习心得体会。采用SSPS 13.0对学生问卷中反映的教学参与情况进行统计分析；对学生上交的心得体会作归纳分析。结果回收有效问卷123份。结果显示，94.31%（116人）的学生认为能积极参与课程学习，90.25%（111人）的学生认为能在教学中积极进行沟通，89.43%（110人）的学生认为自己课前准备充分。收到符合要求的心得体会123篇；多数学生对教学方式带来的各方面积极影响表示肯定；个别学生指出，该教学方式存在投入准备时间过多、教学信息量过大等劣势。结论 PBL联合多媒体网络教学初获成效，该教学方式适用于《影像诊断学》见习。

Objective To investigate the effect of the courses of image diagnostics on clinical pro-bation period via the combination of PBL and multimedia network teaching model. Methods 126 under-graduates from the department of medical image （Grade 2011 and 2012） were selected as teaching subjects, and PBL combined with multimedia network teaching was adopted in the teaching of the course of medical imaging diagnosis. After class we implemented a questionnaire survey, and let the students write learning experience. Statistical analysis was conducted by using SSPS 13.0 to reflect the teaching participation in the students＇ questionnaire and a. summary analysis of the learning experience of the students was also made. Results 123 valid questionnaires were collected. 94.31%（116 people） of students were active participants in these courses, 90.25%（111 people） of the students thought they could actively communicate in teaching,and 43% （110 people） of the students thought they got fully prepared before class. 123 articles in accor-dance with the requirements of experience were received; most students took positive attitude to the active influence the teaching methods had brought; some student pointed out that the teaching method had the disadvantages such as too much time to prepare, too much information, and so on. Conclusions The com-bination of PBL and multimedia network teaching has preliminary results. It is a novel model that is available for teaching image diagnostics on clinical probation period.
