Abstract
Scientific reasoning skills now days become discussed among scholars because its importance in every daily life.As a part of 21 st -century skills, it is necessary to promote it in science courses, especially in biology lessons.The purpose of this research is to enhance students' scientific reasoning skills.Students who participate in this research were enrolled for the plant physiology course.The research was conducted during September-December 2022 at Universitas Negeri Malang.The learning process was carried out through Problem-based Learning.Classroom learning is done by implementing lesson study to improve each learning process.The research instruments were chapter design.Lesson design, lesson plan, and essay test of scientific reasoning skills refer to the rubric of scientific reasoning by the AACU (2010).The scientific reasoning achievement of students in the Plant Physiology course has increased from the initial, middle, and final tests.The average achievement of scientific reasoning on the initial, middle, and final tests, respectively, is 54.17, 63.13, and 72.56.The n-gain score of the scientific reasoning skills of students is 0.65 in the medium category.Meanwhile, the achievement of students' scientific reasoning on the Topic or Argument Selection indicator is 0.58 in the medium category; Existing Knowledge, Research, and/or Views of 0.75 in the high category; Analysis of 0.64 in the medium category; and Conclusions, Limitations, and Implications of 0.57 in the medium category.
