Extraneous Cognitive Load (ECL) Mahasiswa Calon Guru dalam Pelaksanaan Perkuliahan Pendidikan Biologi

This study aims to determine the ECL of prospective teacher students during lectures. ECL is obtained from the mental effort of students in attending lectures or teaching and learning processes because it will affect the process of constructing students' cognitive schemas from the information received during the learning process. Learning activities are effective and efficient if the ECL of students is in the low category. Data collection was carried out on biology education students who attended group lectures for pedagogic courses and biological science content in the odd semester 2020/2021. This is a descriptive study which was conducted in March-September 2021, with the determination of the sample, namely purposive random sampling. ECL was measured using a mental effort questionnaire in each course in the learning process. The data obtained were analyzed in the conversion of low to high scores, then compared between semester levels to provide an overview of student ECL. The results showed that the mental effort of prospective teacher students was in the low category. The ECL of prospective biology education teacher students is low.

ANALISIS PRELIMINERY RESEARCH PHASE MENGGUNAKAN MODEL PENGEMBANGAN PLOMP SEBAGAI DASAR PENGEMBANGAN MODUL BELAJAR DAN PEMBELAJARAN PENDIDIKAN BIOLOGI BERMUATAN HASIL RISET UNTUK MAHASISWA

The purpose of this study is to describe the preliminery research phase data obtained as a basis for the development of learning and learning modules containing research results that will be developed later. The development model used in this study is the Plomp model which has been carried out until the initial investigation data stage. Preliminary investigation data revealed some initial findings including; analyzing the Semester Learning Plan (RPS), interviews with learning and learning lecturers in the Biology Education Study Program FKIP Riau Islamic University, student questionnaire problems in conducting learning and learning lectures, student needs questionnaire in learning and learning lectures, and analysis of learning and learning modules used in learning and learning teaching materials previously in learning and learning lectures. The results revealed in the analysis of the Semester Learning Plan (RPS) there were thirteen topics in learning and learning. The results of interviews conducted with lecturers in learning and learning courses also revealed obstacles in the implementation of learning and learning lectures, one of which was the lack of student references to study learning and learning. Student problem questionnaire revealed that students do not yet have a learning and learning module with a percentage of 13.71%. Student needs questionnaire revealed that students strongly agree the need to develop learning and learning modules containing research results with a percentage of 100%. The learning and learning module that has been used in the learning process does not meet the standards of the Ministry of Research, Technology, and Higher Education Directorate General of Learning and Student Affairs Directorate of Learning in 2017. The conclusion of this study is the need to develop learning and learning modules containing research results for biology students to help the lecture process in the classroom.
