Beban Kognitif Siswa Pada Materi Pencemaran Lingkungan Berbantuan Prezi Application

Cognitive load profile is a theory used to study the limitations of working memory in receiving and processing new information obtained by students, mental effort owned by students and student learning outcomes after learning learning that has been conveyed. This research is a qualitative descriptive study which aims to find out the cognitive load profile of students in grade VII of Sukabumi City Public Middle School on environmental pollution material which was carried out in April in the 3rd week in one of the Sukabumi City Negri Secondary Schools. This study is to describe the emergence of the cognitive load profile of students in environmental pollution material with the help of prezi application. The sample used in this study were 40 students. The instrument used in the study of 16 problem questions according to indicators developed by Marzano to describe ICL, 8 questionnaires during the delivery of environmental pollution material assisted with the Prezi application to describe the ECL and 25 multiple choice questions according to indicators developed by marzano to describe GCL. The results of the study illustrate that the cognitive load profile of Grade VII students of Sukabumi City Negri Middle School in the academic year 2019/2020 illustrates the results of instrisic cognitive load (ICL) in receiving and processing information that has a high average value of 81.25 shows the profile of cognitive load owned by low students, then the results depicted from extraneous cognitive load (ECL) in the mental effort of students obtain an average value of 65.2 it illustrates the cognitive load profile possessed by students and finally the learning outcomes By using Germane cognitive load (GCL), students get an average value of 63, which is the same as ECL, which illustrates students' cognitive load profile because of the low value of learning outcomes obtained by students.
