"Practice and evaluation of team-based learning in teaching of practice lesson of ""aerospace nutrition and food hygiene""" / 中华医学教育探索杂志

Objective To explore the feasibility of team-based learning (TBL) for practice teaching of the aerospace nutrition and food hygiene.Methods A total of 90 students were investigated,and were divided into the TBL group (n=46) and the TL group (n=44) by simple random sampling.After the experiment teaching,a test and questionnaire were used to compare the teaching effect of TBL group and TL group.SPSS 18.0 was used for date and the data was analyzed by Independent-Samples t test and Chi-square test.Results Students in TBL group achieved higher mean test scores (85.70 ± 3.47) compared with students (74.10±2.41) in TL group and the difference was statistically significant (t=8.703,P=0.000).The results of the questionnaire showed that,compared with the TL group,TBL group students more agreed with the positive impact of the teaching methods on their team work ability,interpersonal skills,communication ability,problem-solving and self-learning and other aspects,and the differences between two groups were statistically significant (P＜0.05).In addition,the majority of the respondents in TBL group [93.5％ (43/46)] were satisfied with TBL.Conclusions TBL teaching is better than the TL teaching,and it can significantly improve students' comprehension of knowledge and enhance their learning effect.

Professional training of undergraduate students who need to develop in the teaching of aerospace nutrition and food hygiene / 中华医学教育探索杂志

Aerospace nutrition and food hygiene is a subject elucidating the effect of aerospace envi-ronment on nutrition and food hygiene which is closely related to health of flight personnel. The teaching work should be in the aim of raising battle effectiveness and enforcing the primary professional capability of students. The most required theory and techniques in both peacetime and wartime was the priority of teach-ing fulfilling mainly through practical or in-site learning. The examination was composed of test paper, ex-periments and health propaganda. The teaching evaluation relied on feed-back of the army on which the teaching plan was revised. Survey in three straight years indicated the exploration enhanced teaching quality significantly.
