Research On Middle School Chemistry Blending Learning Mode Based On NOBOOK Virtual Laboratory

Chemistry is an experimental-based natural science,and experimental teaching is an important part in middle school chemistry teaching.Traditional middle chemistry laboratories have insufficient funds,so experimental teaching conditions are limited.Teachers often use the method of “painting experiment” to conduct chemical experiment teaching,which is extremely unfavorable for cultivating students' core literacy.With the help of the chemical virtual laboratory,not only benefits the individualized development of students,but also provides more choices for teachers' "teaching" and students' "learning".The era of "Internet + education" has arrived,the combination of Internet and education will bring greater opportunities for basic education.After deep thinking about the shortcomings of school chemistry experiment teaching,the author creatively proposed a new idea based on NOBOOK virtual laboratory for middle school chemistry blending learning,aiming at giving full play to the advantages of the Internet and making up for the current experimental teaching with the help of emerging information technology.thus activating experimental teaching resources,extending the spatial dimension of teaching,and providing more teaching and learning possibilities for the development of chemical experiment teaching.This thesis focuses on the model construction of middle school chemical blending learning with NOBOOK virtual laboratory.Through the investigation of students' chemistry experiment learning status,the author deeply excavate the basis of theory,according to the "student-centered" thinking,with the help of "We-Chat public platform" and "NOBOOK chemical virtual laboratory software",based on ADDIE systematic teaching design Complete the construction of a blending learning model.The author has carefully designed the operation process of each teaching link in the blending learning model,which makes the advantages of traditional classroom and the advantages of Internet teaching closely combined,and presents an efficient chemical experiment teaching system.Finally,"Testing the Preparation and Properties of Chlorine Gas",is selected as the teaching courseware.The teaching model is carried out in the internship school in combination with the blending learning model proposed by the author.The research results show that: the blending learning of middle school based on NOBOOK virtual laboratory is very effective in middle school chemistry experiment teaching.Students show great enthusiasm for this teaching mode and have a strong interest in learning.After interviewing the teachers,three opinions were put forward: the formation of a mixed expert team;the improvement of teachers' professional ability;the improvement of students' self-learning ability,and the reference for the further development of the mixed teaching mode of middle school chemistry experiment.
