Development And Application Of School-based Senior High School Biology Experiment Curriculum Based On Scientific Inquiry Literacy

In recent years,China has been continuously promoting and deepening the basic education reform.It is clearly indicated in the “Biology Curriculum Standard ” that the curriculum standard should comply with the requirements of the times to accelerate upgrading the personnel training mode,strive to improve the personal capability of students and actively develop the core literacy of high school students in biology,wherein one key point is the cultivation of scientific inquiry literacy.It can effectively enhance the scientific inquiry literacy of students to carry out senior high school biology experiments,especially the research-based learning experiments.However,in view of the insufficient biology class hours of senior high school and the exam-oriented education mode with the college entrance exam as the baton,the inquiry biology experiments carried out in each school can not yet satisfy all students’ demand for scientific inquiry,which is contradictory with the requirements to core literacy as stipulated in the “Biology Curriculum Standard ”.Nevertheless,the school-based curriculum,as an important supplement of national and local courses,can well make up for the deficiency of classroom teaching.Relying on Chongqing Yangjiaping High School where the author works as a teacher,the author has conducted research on the relevant content of the scientific inquiry literacy of senior high school students by virtue of the school-based extended senior high school biology experiment curriculum.In this thesis,the literature research method is adopted to define the relevant concepts of biology experiment and senior high school biology experiment,scientific inquiry literacy and inquiry experiment,as well as school-based curriculum and Elective courses,an overview is conducted on the current situation of development and application of domestic and foreign school-based curriculum and the literature related to scientific inquiry literacy and school-based senior high school biology experiment curriculum,and an investigation is carried out on the teachers and students of our school by means of survey and interview methods,so as to analyze the implementation status of biology and inquiry biology experiments in our school,the students’ interest in experiments,the demand of students for inquiry experiment,the development status of school-based curriculum and the feasibility of developing school-based biology experiment curriculum.The teaching content of 10 class hours is sorted out and the school-based textbook that conforms to the situation of our school is compiled combining with the relevant requirements of the “Biology Curriculum Standard ”,the questions of the textbook experiment listed by the high school students and the experimental topics that they are willing to further explore.Meanwhile,the school-based curriculum is developed based on Skil’s environmental model.In the case of the same teacher(the author)teaching,the students of three experimental classes are taught for 10 class hours by using the school-based textbook compiled by the author by means of inquiry experiments to solve the students’ doubts in classroom experiments.For the students of one control class,the traditional teaching is carried out for 10 class hours by using the biology textbook,and the teacher answers and explains the students’ questions in the experiments directly.Before and after the implementation of the school-based curriculum,the pre-and post-tests and final exam test for the level of scientific inquiry literacy are held for the students of the control class and the experimental classes,respectively.The students’ academic work is evaluated through the school-based curriculum student evaluation scale and student achievement display,and the curriculum itself is assessed through the school-based curriculum evaluation scale and the interviews with teachers and students.The investigation results show that the biology experiments in our school are well carried out,and the inquiry biology experiments are better implemented,but some students still have questions or inquiry needs about the experiments in the textbook.In order to meet the inquiry needs of these students,promote their diversified development and practice the educational philosophy that everyone can achieve great success in our school,it is very necessary to carry out the school-based senior high school biology experiments based on scientific inquiry literacy.The author has compiled the school-based textbook—“Biological Experiment Inquiry! Re-inquiry” based on the investigation results,and the school-based curriculum is implemented for students in the experimental classes by using the school-based textbook.The results of the pre-and post-tests before and after the implementation of the school-based curriculum and the final exam test show that the implementation of the school-based curriculum“Biological Experiment Inquiry! Re-inquiry” can significantly improve students’ scientific inquiry level and final exam scores.Before the implementation of school-based curriculum,the average scores of the pre-test of scientific inquiry level of the control class and the three experimental classes are 63.37±8.44(Mean value±Standard deviation,the same in the following text),64.64±9.91,65.52±12.08 and64.72±8.03,respectively.The further independent sample t-test shows that the P values are all larger than 0.05.The average scores of the final exam for the second semester of Senior One in the control class and the three experimental classes are 70.08±7.28,69.94±9.81,69.78±9.31 and 70.35±9.88,respectively before the experiment.The further independent sample t test shows that the P values are all larger than 0.05,suggesting that there is no significant difference in the scientific inquiry level and student score between the control class and the experimental classes before the implementation of school-based inquiry experiment curriculum.After the implementation of school-based curriculum,the average scores of the post-test of scientific inquiry level of the control class and the three experimental classes are 69.59±7.89,81.53±9.59,78.09±9.67 and80.30±8.05,respectively.The further independent sample t-test shows that the scientific inquiry level of the three experimental classes has been significantly improved than that of the control class(p < 0.05).The average scores of the final exam for the first semester of Senior Two in the control class and the three experimental classes are67.00±7.76,72.78±7.97,71.68±5.91 and 71.60±7.16,respectively after the implementation of the curriculum.The further independent sample t test shows that the final exam scores of the three experimental classes in the first semester of Senior Two are significantly higher than those of the control class(p < 0.05),indicating that there are significant differences in the scientific inquiry level and student score between the control class and the experimental classes after the implementation of the school-based inquiry experiment curriculum.It can be seen that the students’ inquiry-based learning capability and biology score have been improved through learning the school-based curriculum “Biological Experiment Inquiry! Re-inquiry”,which makes up for the impact of traditional teaching that focuses on theory and ignores practice on students’ diversified development.The students’ application ability has also been improved through course learning;they can design inquiry-based learning topics independently and win awards in the inquiry activity competitions organized by the school,and apply the knowledge they have learned into practice.In conclusion,the practice of school-based senior high school biology experiment curriculum based on scientific inquiry literacy can effectively improve students’ scientific inquiry literacy,satisfy the diversified development needs of some of them,and improve their inquiry and practice ability.In this research,elective courses are used to carry out school-based extended inquiry experiment curriculum,which has made up for the deficiency of some students in their inquiry literacy,proposed a set of school-based curriculum schemes and implemented them,and provided some referential experience that may draw lessons from for the majority of front-line teachers in developing school-based extended biology experiment curriculum.
