This study compares five high school economics textbooks to identify whether they accurately reflect the purpose of the 2015 national curriculum and help to achieve the educational goals of economics. In three textbooks, the topic of minimum wage only focuses on the side effects of increased minimum wage rates, which fail to provide students with the opportunity to explore the positive and negative aspects of minimum wage. As for market and government failures, there is far more content on market failures than government failures, which is far from the goal of balanced statement. In the description of asymmetric information, a newly introduced concept in the 2015 curriculum, some textbooks only define the concept and make it difficult for students to logically distinguish between asymmetric information and market failure. Some textbooks also fail to provide enough materials to debate the pros and cons of fiscal policy and monetary policy, making it difficult for students to form their own opinions. To make classroom debates about free trade more effective, more relevant materials need to be provided in textbooks.
