Abstract
The purpose of this research was to develop a research-based reference book and applied it through the problem-based learning (PBL) using reference books in learning activities. The method for the reference book used the ADDIE development models. The reference book's effectiveness test results were conducted using a purposive sampling technique, with a total sample of 55 students and analyzed by t-test. The research results showed that the reference books of the development results were validated by media experts and material experts. The integration of the development of reference books in learning activities has an impact on increasing student understanding as demonstrated through the pre-test and post-test scores that differ significantly with t-value> t-table (4.149> 2.045) at p <0.05. Therefore, the development of the insect's immune system book with the PBL model increasthe student learning outcomes significantly. Also, this research has been able to improve students' ability and competence in solving problems in insects' immune system subject matter.
Highlights
Educational problems that are developing nowadays include complex educational issues (Lewis, 2015)
The results showed that only 45% of students understood animal physiology material thoroughly with completeness standard more than 66
Students need books and subject matter of development as a result of research form the basis of developing books. This stage is obtained from my field observations in the Department of Biology Education, Universitas Lampung in Animal Physiology lectures
Summary
Educational problems that are developing nowadays include complex educational issues (Lewis, 2015). The development of various models and methods of learning, learning media, evaluation techniques, and curriculum improvements continue to be made to deal with learning problems (Fajarianingtyas, Akbar, & Herowati, 2019; Taufik et al, 2010). This is done to achieve learning outcomes for students following the objectives of education, especially in Indonesia. Content of the chapter of the book: o Introduction to the main topic o Presentation of natural phenomena related to insects and their defense regulation o Issues regarding the topic in chapter division of the Insect Defense system mechanism Content.
