With the arrival of the new era,China’s rapid economic development,science,and technology innovation,under the "people-oriented" concept,basic education reform is in an orderly way,teachers at the front line to explore to find the best teaching model for students’ development.The teaching mode of " three questions and three explorations " appeared after experiencing constant attempts to modify the experiment.This model is based on the premise of students’ initiative to ask questions.Students first explore the problem by themselves,and then cooperate to solve the problem when they cannot solve it by themselves.It can not only cultivate students’ autonomy,but also cultivate their ability of inquiry and cooperation.Let students in the process of solving problems focus on mastering methods,the formation of problem awareness in the mind,improve the problem-solving ability of students.Chemistry is a subject closely related to our life,and students’ future life development cannot do without chemistry.However,the knowledge points of high school organic chemistry are many and scattered,and the contents are not closely related,so it is difficult for students to learn.There is an urgent need for a teaching mode to help students learn,and the teaching mode of "three questions and three inquiries" can just solve this problem.Therefore,the chemistry discipline is trying to explore the mode and organic chemistry classroom teaching close combination,change the low efficiency of students’ organic chemistry learning status,improve students’ chemistry performance,cultivate the ability of development of the era of youth.After studying the literature related to the teaching mode of " three questions and three explorations ",this paper investigated the current learning status of senior one student in organic chemistry through preliminary questionnaire survey.Combined with the teaching mode of " three questions and three explorations ",this paper designed a two-hour teaching case of "Ethylene” and took the chapter of "Organic Compounds" in high school as an example.The organic chemistry teaching practice was carried out for one month for the two classes.Through the scientific evaluation table,the students’ learning autonomy,cooperative inquiry ability and problem-solving ability are investigated,and the results of pre-test and post-test are analyzed.Finally,the results are analyzed based on the students’ performance,and conclusions are drawn,and deficiencies are summarized.The practice results show that the mode of "three questions and three explorations" has significant effects on improving students’ learning autonomy,cooperative consciousness,inquiry ability and problem-solving ability,and students’ grades in organic chemistry have also been greatly improved. |
