| Education is an irresistible trend,push the important mission of cultivating talents and developing human society since the 21 st century.People realize that science education has an irreplaceable role in personal development through the comparison of past.Science education has laid the foundation for the improvement of the scientific literacy of the all people and the construction of an innovative country,from the long-term stability and vigorous social development of country.The leading and basic nature of compulsory education ascertains its important position in China's education system.The first grade of elementary school as the starting grade of the science curriculum and proponent the cultivation of students' scientific literacy by miscellaneous teaching methods,it is proposed in the latest edition of "Compulsory Education Primary School Science Curriculum Standards".Following this modern education reform concerned with the different stages of joint teaching that conforms to the law of cognitive development of students.Based on this,the thesis discusses the teaching of junior middle school chemistry and elementary science based on the different learning styles and cognitive abilities of primary school students and junior high school students.The thesis conducts an interview survey and questionnaire survey on some junior high school students ?junior middle school chemistry teachers and graduate students those who are about to enter the teaching discipline in Kaifeng City.It aims to understand the students and teachers to learn the attitude towards elementary school science courses and junior middle school chemistry courses and their views on the teaching connection of different grades.The questionnaire survey indicates the following results:(1)Different stages of learning,students learning attitudes,teachers teaching concepts,and the importance of parents will all affect the students liking for the curriculum.Most junior high school students have a strong interest in primary school science courses and junior high school chemistry courses.Primary school science courses have a lower interest in chemistry courses,14% of students with lower interest at the elementary school level.There are 28% of students with low interest in learning.It can be seen that the popularity of elementary science courses is higher than that of junior middle school chemistry courses.(2)The junior high school teachers think through the teaching process,the content of junior high school textbooks can be appropriately added to expand the students' knowledge.Students can better understand and accept the chemistry subject to a certain extent with the content of the previous study in junior middle school chemistry teaching,it is believed by junior middle school chemistry teachers.It can be seen that the teachers expressed support for the teaching connection.Hence,teachers are not optimistic about the familiarity of the curriculum standards and textbooks of different grades.Based on the survey results,the thesis analyzes "Compulsory Education Primary School Science Curriculum Standards" and "Compulsory Education Chemistry Curriculum Standards" from the preface,course content,course objectives,implementation suggestions,etc.,to provide theoretical support for the connection teaching.Among them,the connection between junior high school chemistry and elementary school science courses is first divided from the connection field,and each connection field is divided into several connection points,a total of ten connection points: water,air,material changes,plastic products,metals,energy conversion,Carbon monoxide poisoning,water conservation,energy use and environmental protection,and the use of simple instruments.In addition,the present textbook elementary school science textbooks and junior middle school chemistry textbooks currently used in Kaifeng City are analyzed in terms of presentation methods,column settings,and knowledge connections.Focus on the most part of theconnection content(water,air,material changes,materials,the use of simple instruments)space comparison,content brief and connection suggestions.In the connection proposal,according to the characteristics of the curriculum and the characteristics of the students' psychological development,they give practical and feasible suggestions to the teaching of junior high school respectively.In order to better reflect the feasibility of the connection concept in actual teaching,the thesis shows the role of teaching connection in the actual classroom implementation through case design. |
