Synopsis

This is the last lesson in the series of lessons conducted to teach Linear Law to Sec 4 Additional Mathematics students. They have learned how to linearise non-linear functions and how to obtain parameters of the general form of the model of equations, by manipulating the gradient and Y-intercept found using the linearised graph.

Students will now attempt the task on using this concept to determine whether a quadratic model or exponential model is a better equation to model the number of confirmed cases during the initial outbreak of COVID-19. The lesson aims to bring in real-world scenario to allow students to apply concepts they learned during their lesson and see the relevance of the concepts learned. While the model(s) used for modelling an actual pandemic outbreak is far more complex than the models used in this lesson package, this lesson is simplified and tailored to the needs and progress level of students. Along the way, the initial lesson plan and learning materials has also been modified to adjust to the progress level of students.

This lesson also showcases the multiple usage of LLM-assisted, AI-powered development of HTML-based interactives and teaching tools. The original lesson package was also developed with teacher-driven use of AI. The development of the learning materials will continue to be beneficial to teachers teaching Additional Mathematics in the area of the teaching of Linear Law. The Linear Law graph plotter will continue to positively impact the work of teachers, even if they do not wish to use this set of learning materials, as they can use it in the area of teaching Linear Law and use it to help them with setting of worksheets and papers.
