A Core Literacy-Based Study Of High School Trigonometry Unit Teaching Methodology

In the wave of the new basic education curriculum reform,General Senior High School Education is facing great challenges and opportunities when it takes the lead in reform and innovation.The core literacy of mathematics is not only based on the concept of "core literacy",but also on the concept of "quality education".To develop and nurture students’ core literacy in mathematics,we need to use basic knowledge,basic skills,basic activity experience,and basic ideas and methods as the carrier,use teaching materials as the basis,and use specialized teachers as the main force to design and implement unit teaching based on deep learning and pointing to core literacy.Trigonometric functions are a continuation and refinement of the learning of functions in high school.As the most typical functional model describing periodic phenomena,it plays an important role in the learning of mathematics in high school.The Trigonometric functions in high school mathematics textbook is a system,the continuation of the general study of functions,that is," study background,general definition,graphical,inductive properties,generalized application ".The study of Trigonometric functions helps students develop their core literacies of mathematical modeling,intuitive imagination,mathematical operations,logical reasoning,and mathematical abstraction,etc.This study firstly organized and analyzed the literature to clarify the theoretical basis of the research content and the current status of the research.Secondly,in the model construction stage,through in-depth literature reviews,research on high school teachers’ learning of unit teaching and implementation,and analysis of senior students’ cognition of functions and acute Trigonometric functions,a model of high school trigonometric unit teaching pointing to core literacy was constructed.Finally,the model correction and summarization stage was held,in which the imperfections in the model were corrected and the teaching practice was summarized by post-testing the students in the experimental and control classes and interviewing the corresponding teachers and students after the teaching of Trigonometric functions.In the whole research process,the author used the literature research method,questionnaire survey method,interview method,and experimental research method to solve the key problems in each step.After the implementation of the unit teaching model,comparing the assessment indexes of the experimental class and the control class,all the data of the experimental class were better than those of the control class,which means that the Unit teaching model pointing to core literacy is effective in the teaching practice of Trigonometric functions.The author believes that Unit teaching methods are effective educational methods that promote students’ learning from passive learning to active learning and then to learning to learn.Unit teaching enables students to participate wholeheartedly in challenging learning tasks to achieve that students can acquire positive learning attitudes,good learning habits,and a rational learning spirit from learning.Secondly,unit teaching is an important tool to promote students’ core literacy development.Core literacy needs to be cultivated and developed under the overall teaching mode,which is in line with the progressive nature of literacy development.It helps teachers’ professional and contemporary development and the development and innovation of the school’s teaching and research.The unit teaching model needs to be constantly practiced and revised,and finally,as a result of the school’s achievements,it is a paving stone for the school’s teaching and research.
