Learning Tools Development to Improve Students Critical Thinking Skills on the Topics of Plant Structures in Technology through Guided Discovery Learning Models
Journal of Advances in Education and Philosophy
The PISA report illustrates Indonesia's ranking in terms of critical thinking among students is still below the average of other countries from year to year. Critical thinking skills are very important skills that are trained in students to be able to compete in various fields. The success of achieving the learning objectives lies in the ability of the teacher to carry out the learning process and the success of the learning process lies in the learning device as a standard so it is necessary
... o it is necessary to develop the learning device. The purpose of this study is to produce learning tools that train critical thinking skills of junior high school students on plant structure material and their use in technology using a guided discovery learning model that is valid, practical and effective. This study uses the Tessmer model, which consists of: 1) self evaluation; 2) expert review; 3) one-to-one; 4) small group; 5) field tests and products produced in the form of complete learning tools, namely: syllabus, teaching materials, student worksheets, student critical thinking skills assessment sheet, teacher activity evaluation sheet, student activity evaluation sheet. The subjects of the study were 8 th grade students at SMPN 1 Angsana. The results of this study indicate that the device passed the test based on validity, practicality, and effectiveness. Another finding is that students are considered capable of being at a good level of critical thinking.
