Abstract

Recent research shows that students ability to read and create phylogenetic trees (tree thinking) is low, meanwhile phylogenetic analysis has become one of the demands on the 2016 version of the 2013 curriculum. Learning using phylogenetic trees is thought to be able to train critical thinking skills as the demands of the 21st century. However, the use of phylogenetic worksheets, especially on Spermatophyte, is often skipped in learning activities at School. The aim of this research is to determine the improvement of students tree thinking and critical thinking skills after implementing phylogenetic worksheets in Spermatophyte learning as a visual representation of tree-thinking abilities. This research type is experimental research that involving one research group totaling 29 students. The research data were collected with several research instruments as if 25 multiple choice questions of tree-thinking test instrument and 10 essay questions of critical thinking test instrument. The interview were conducted to obtain supporting data Results show that learning by implementing phylogenetic worksheets is quite effective in increasing critical thinking skills (59.2%) and tree-thinking skills (61.7%) with an average increase of both in the medium category. Spermatophyte learning using phylogenetic worksheet can be used as an alternative learning activity because it can improve tree thinking and critical thinking skills.
