Analyse Difficult Point And Congnitive Biases Of High School Math From Wrong Cases

There are many difficulties in current high school mathematics classroom teaching. Even thoughreference books have highlight most of the difficult points in each chapter, for those issues which arenot mentioned, it is easy to create cognitive bias to some students. These students make mistakes quiteoften because they have kind of wrong thinking tendency when they meet such problems. So what arethe difficult points of high school teaching? Which difficulties cause cognitive bias? How teachershelp to shoot these troubles need to be further discussed.In order to help high school mathematics teachers to cope with these issues better, also make ourstudents understand these difficult points clearer, know better about the principle and solve theproblems faster, the questions above will be further analysed in this paper.Document, text analysis and expert consultation will be applied in this paper. I will look up themath difficulties and the related cognitive bias through various of documents to collect information;study on the specific mistakes make by students to find the cognitive bias; find out the informationfrom expert as follows:1. the understanding of difficulties of teachers;2. the acknowledgement ofstudents cognitive bias;3. the suggestion of math troubleshooting.I will combine and anylyse the information gathered from these three aspects through document, case study and expert consultation, and get final conclusion of the research.
