Abstract

No research has been conducted in the Pagat tourist area which has various types of ornamental plants that can be processed as teaching materials in the form of popular scientific books based on local potential to train high school students' critical thinking skills. The purpose of this study was to describe the effectiveness of popular scientific books. The research method uses formative evaluation based on Tessmer's design which consists of self-evaluation, expert validation (3 lecturers), individual test (3 students), small group test (5 students) and field test (10 students). The results of the research on the effectiveness of the BIP as a result of the development found that the criteria were very good for use by high school students because they had been fulfilled, which meant that the BIP was easy to use. This is supported by the positive response from students towards learning using the developed BIP. Students' critical thinking skills are included in the medium category with an average N-Gain of 0.5 so that they can be implemented in learning. In conclusion, the development of BIP development results is effectively used in an effort to train students' critical thinking skills.Abstrak Belum ada dilakukan penelitian di Kawasan objek wisata Pagat yang memiliki berbagai macam jenis tanaman hias yang dapat diolah sebagai bahan ajar berbentuk buku ilmiah popular berbasis potensi lokal untuk melatih kemampuan berpikir kritis siswa SMA.
