An Analysis Of The Influencing Factors Of Science-related Career Expectations For Middle School Students

In an era of scientific and technological progress closely related to the transformation of industrial structure and rapid economic development,the importance of science-related talents is increasing.However,the willingness of teenagers to engage in science-related professions in the future is not high.Especially in the general view,science achievement is positively correlated with science-related career expectations.Chinese students performed well in the PISA2015 test in science literacy,but the proportion of students who choose science-related fields as future careers lags far behind East Asian countries and many developed countries.It shows that the current development of scientific literacy in our country places more emphasis on academic behavior rather than future scientific career interests and choices.Therefore,this study tries to answer how to improve students' science related professional level at the national and school level.The main research conclusions are as follows:(1)Comparing the proportion of students with science literacy and science-related career expectations in the 72 countries tested in PISA2015,it is found that the relationship between science literacy and science related career expectations at the national level is complex and non-simple linear trend.(2)By comparing the average values of the four participating mainland provinces and cities including Chinese Macao,Chinese Taiwan and Chinese Hong Kong,East Asian countries including Japan,South Korea,Thailand,some developed countries including Australia,Canada,Singapore,the United Kingdom and the United States,and the mean of Organization for Economic Cooperation and Development countries,we find under different national backgrounds,students' choice of science-related careers is related to the country's economic conditions,the country's investment in education,cultural traditions and other factors.Under similar cultural and economic backgrounds,students' expectations for future science-related careers are related to school education.(3)Based on PISA2015,the binary logistic model is used to analyze the influencing factors of science-related career expectations in four provinces and cities in China,and discover students' instrumental learning motivation,scientific interest,interest in general scientific topics,and science-related career aspirations of the peer group and parental science-related career expectations have a significant positive impact on students' choice of science-related careers.(4)Adopting a disorderly multi-category logistic model to analyze the four groups of students including expecting high scientific literacy and science-related occupations,non-high scientific literacy and science-related occupation expectations,high scientific literacy and non-science-related occupation expectations,non-high scientific literacy and non-science-related career expectations.The analysis found that students' instrumental learning motivation and the career aspirations of peer groups are significant factors that influence the expectations of students with high scientific literacy levels in choosing science careers.Factors such as teacher's teaching style and students' interest may influence students' choice of science-related careers through students' performance.Based on the research conclusions above,the following three suggestions are put forward on how to improve the expectation of science-related occupations for young people in my country: broaden the team of science-related professionals to enhance the professional influence and social reputation of science practitioners;innovate the school science learning model to increase students' enthusiasm of exploration in science careers;strengthen the planning and implementation of career education,and guide students to make their positive and independent career choices.
