Objective:To revise the children's perception of interparental conflict scale (CPIC) developed by Grych and his colleagues and examine its reliability and validity Method:Data were collected from a sample of 303 primary school students tested with the CPIC scale Results:The results of factor analysis and hierarchical cluster analysis showed that the revised CPIC had a good construct validity; and ?coefficient of the whole scale is 0 879, the reliability coefficient of split-half is 0 865, and the ?coefficient of each dimension was more than 0 657 Conclusion:The CPIC scale is suitable for Chinese children after revision

Objective: Exploring the reliability and validity of Chinese version of The Social Support Appraisal (SS-A) scale developed by Vaux et al (1986) and the characteristics of adolescent's social support.Methods:Using the scale, 515 junior and senior high school students were investigated.Results:(1) The SS-A scale had internal consistency of 0.91 for the scale and of 0.81-0.84 for three dimensions and a three-factor model was supported by the data (?2/df

Medical Physics is an interdiscipline which is formed by applying the basic principles, methods, and techniques of physics to clinical medical research such as prevention, diagnosis, and treatment of human diseases, and it is a compulsory professional basic course for medical students. However, there are many medical students reflect that the content of this course is obscure and difficult to understand. Teaching effect is not ideal. The main reasons are that the teaching method is single and the reference materials are few. Based on the actual situation of the course, Hebei Medical University, China promotes formative evaluation from the content of teaching materials, teaching means, and other aspects. At the same time, by combining with the Internet, the digital construction has been realized, deepening the reform of the Medical Physics curriculum, and remarkable results have been achieved.

Objective:Through constructing an online question database of medical physics, teachers and students can make use of the Internet to realize interaction in or after class, so students' ability of independent learning and the quality of teaching can be improved.Methods:Based on teaching outlines, the type, quantity and difficulty of the test questions were discussed and determined by teachers in the teaching and research office, and the online question database of medical physics was constructed with the help of Internet platform to realize self-testing and teacher-student interaction.Results:Through the construction and application of online question database, students' learning initiative was mobilized, the effectiveness of teacher-student interaction was improved, and empirical materials for teaching formation evaluation were obtained. Self-examination and teacher-student interaction help improve students independent learning and problem solving ability. And data generated on the platform enable teachers to know students' learning situation and their teaching quality.Conclusion:The construction and application of Internet + digital online question database of medical physics can greatly promote the teaching effect.
