Abstract: How to design textbook is one of the important issues in the research field of vocational textbooks. Under the idea of project-based vocational curriculum, it’s unreasonable to see the reductive phenomenon in vocational textbook design, as the diversification of vocational education and its curriculum inherently requires the diversification of vocational textbooks. Based on three dimensions, vocational textbook models can be defined at nine levels. The first dimension is vocational, which can be defined at the levels of relevance, task and project. The second dimension is knowledge, which can be defined at the levels of theory, practice and experience. The third dimension is learning, which can be defined at the levels of narration, conversation and activity. By combining these three dimensions and nine levels, we can get five typical vocational textbook models. An in-depth analysis of the models can offer essential methodology for vocational textbook development.
