Description

Covid19 has spread globally. When the Covid-19 pandemic occurs, schools must be closed or partially opened, which affects teaching and learning. Educational innovations to deal with epidemics such as Covid-19 and other urgent epidemics are very important. Therefore, the three cores of Education 4.0 knowledge applicable to pandemics such as COVID-19 are simple, self-learning and technology-integrated knowledge (SST knowledge).

Simple knowledge is the most important core of Education 4.0, it same as Albert Einstein quotes: everything should be made as simple as possible, but not simpler, If you can't explain it simply you don't understand it well enough, We cannot solve our problems with the same thinking we used when we created them.

Using Peter Chew Rule for Solution of Triangle to solve the same problem is a simple, direct and accurate method to compare current methods. The Peter Chew Rule is the same as the sine rule, both are easier to solve than others rule for certain types of problems.

Use Peter Chew rule in Peter Chew Triangle Diagram to make the diagram guide students to solve any problem of the topic solution of the triangle become simple with just one rule.

Programming Peter Chew Triangle Diagram as Peter Chew Triangle Diagram Calculator makes it easier for the calculator to guide and solve any problem of the topic solution of the triangle with just one rule, which will strengthen technology-integrated education, making teaching and learning more effective and fun.

2nd Edition update some information and add Memorization Techniques for Peter Chew rule.
