Teaching Mathematics at Upper Secondary School in the Digital Age: A Case Study in Cambodia

The research showed (1) Necessity, (2) Challenges, and (3) Solutions in teaching mathematics. At the same time, teachers, learners, and stakeholders were encouraged to develop soft skills and hard skills that intervened positively to ensure the quality of education in line with regional and global educational trends to achieve the goal of education for all in the new millennium. However, surveys clearly show that limited digital technology and inadequate digital materials were at the root of the problems. Practical observations provided a fair number of results and some points showed the relationship between the quality of teaching and learning in supportive strategies. The research questions were: (1) What are the requirements for teaching mathematics at the high school in the digital age? (2) What are the challenges of implementation of mathematics teaching at the high school in the digital age? (3) What are the solutions for teaching mathematics at the high school? The research methods through quantitative data were collected from principals, deputy principals, deputy directors, technical team leaders, mathematics teachers, and high school students through questionnaires in Khmer language to investigate the link between teaching management and mathematics learning where N (principals, teachers, students) = N (90,158,933). The results of the analysis on ( )1 2 3 x =2.96 , x =3.26 , x =3.32 and F(2 , 36) = 8.534, p < 0.05 showed that the conceptual framework expressions for the three independent variables were quite different and teaching mathematics was challenging more than solutions and needs which were lower than finding solutions. In this sense, teaching materials and teaching talent were the main keys to improving the quality of education while the situation was not good; it was unsuccessful because the support or implementation of information and communication technology and technology was still limited and the use of teaching strategies showed positive and negative effects as arguments for further study on the application of teaching methods.
