With the change of the times and the improvement of talent assessment standards, the teaching concept of "score first" in examination-oriented education has been eliminated by the times. The teaching model that only focuses on students' scores is difficult to meet the current teaching needs. This is especially true for junior high school science, a discipline that cultivates students' scientific concepts and thinking ability. Blindly following traditional teaching methods will hinder students' progress and growth, dilute students' learning interests, and also fail to meet the teaching objectives set by the discipline. Therefore, teachers must make changes. This paper will analyze the scientific strategies to effectively improve the quality of junior high school science teaching.展开更多

METHODS: The marker gene, pbLacZ, was transferred into cultured BMSCs and the expression of transduced gene by X-gal staining was examined. Then plasmid pcDNA3-rhBMP7 was delivered to cultured BMSCs. Through immunohistochemical staining and RT-PCR assay, the expression of rhBMP7 gene was detected. RESULTS: The exogenous gene could be expressed efficiently in transduced BMSCs. CONCLUSION: The present study provided a theoretical basis to gene therapy on the problems of bone and cartilage tissue.展开更多

As an art form, film has a certain educational function. In the creation of film and television, it is not only a film and television work, but also a special place that exists independently on the screen and can be transmitted. The educational meaning conveyed by film art can be easily accepted by students, which can make students get aesthetic experience and resonance;At the same time, it can also stimulate students' inner positive emotions or negative thoughts, so as to achieve the purpose of guiding students' values. Through film art education, can very well cultivate students' healthy psychology, noble sentiment, for the overall promotion of quality education is of great help. This article on the background of quality education film art education exploration, published some of their own views.展开更多
