The Action Research Of Intergrating HPM Micro-course Into Mathematics Teaching In Senior High School

Under the background of new era of the Internet + mathematics education,this research integrated the history of mathematics and micro-course together basing on the trigonometry knowledge points,such as the sine formula of two angles,law of sines and law of cosine,and the existing HPM research achievement.This research mainly studied three questions.What was the research framework of HPM micro-course? What was the influence on students about integrating HPM micro-course into mathematics teaching in senior high school? What was the effects on teachers about integrating HPM micro-course into mathematics teaching in senior high school?In order to answer three questions,this research established the research framework of HPM micro-course autonomously to expound basic links of analysis,design,production,application and evaluation of HPM micro-course.Then it took action research methods to carry out teaching and researching,which researched the educational value of students and the influence of the professional development of teachers by intergrating HPM micro-courses about the sine formula of two angles,law of sines and law of cosine into mathematics teaching in senior high school,the main conclusions are as follows:(1)The influence on students are as follow: HPM micro-courses promoted students to know about the ins and outs of knowledge,improved them understanding of mathematics knowledge,and cultivated the core literacy of mathematical discipline,such as intuitive imagination,logical reasoning,mathematical operation.At the same time,the independent learning abilities of students was developed,the interest of mathematics study was promoted,the scientific spirit was cultivated and the mathematical culture was tasted.(2)The influence on teachers are as follow: In terms of beliefs,the mathematical beliefs and the mathematical teaching beliefs of teachers were changed with the trend of dynamic mathematical concept,so teachers had deeper understanding to the students' cognitive regularity and showed a more tolerant attitude for students' mistakes.In terms of knowledge,subject matter content knowledge and pedegogical content knowledge of teachers were increased distinctly.In terms of abilities,the abilities of teaching design and educational information technology were improved.
