Development of Stem-Based Learning Tools to Increase the HOTS of Class X SMA Students on Environmental Change Materials

Abstract

Pery Jayanto, Development of STEM-Based Learning Tools to Increase HOTS of Class X SMA Students on Change Material. Yogyakarta: Faculty of Mathematics and Natural Sciences Yogyakarta State University, 2021. The objectives of this research are (1) to produce STEM-based learning device products in the form of RPP, LKPD and valid assessment instruments so that they are feasible to be applied in learning activities, (2) produce practical STEM-based learning device products that are easy to apply in learning activities, and (3) produce effective learning equipment products to increase the HOTS of class X SMA students on Environmental Change Material. This research is a research and development (R&D) using the ADDIE model which consists of the stages of analysis, design, development, implementation, and evaluation. STEM-based learning tools developed are evaluated for the validity of the learning tools developed determined from the opinions of experts. Experts in this case are UNY Postgraduate lecturers, material experts and instrument experts who will provide suggestions and assessments related to the validity of the learning tools developed and then tested for practicality on the developed learning tools that can be determined through teacher and student assessments. This assessment is used to determine the responses of users of the learning tools developed. This assessment is about how suitable and easy the learning device is to apply and test its effectiveness on class X SMA students using a quasi-experimental pretest-posttest control group design. Data collection used interview guides, needs analysis questionnaires, validity assessment questionnaires for material experts and learning experts, practical assessment questionnaires by biology teachers and students and students' HOTS tests. The data analysis technique used n-gain and independent sample t-test. The results obtained based on the research that has been carried out show (1) according to the results of the validation of material experts and instrument experts, the STEM-based learning tools developed are declared valid and suitable for use in terms of construction, material and language aspects (2) the use of STEM-based learning tools in activities practical learning to use according to the teacher's assessment which is assessed from the material aspects, lesson plans and student worksheets, while the practicality of learning tools by students is assessed from the aspect of ease and assistance of students in using LKS, and (3) learning using STEM-based learning tools can increase participant HOTS SMA XI class students on environmental change material with a value <0.05.
