Systemic Thinking Processes Of Preservice Teachers With Systematic Cognitive Style In Solving Complex Problems

Abstract

Systemic thinking is a simple technique for finding the focus of the system. Systemic thinking is also defined as looking for and seeing that everything has an orderly pattern and works as a system. The objectives of this research are 1) to find the stages of systemic thinking; and 2) analyzing the systemic thinking process of preservice mathematics teachers who have a systematic cognitive style. This research uses qualitative research method. The main instrument of this research is the researcher with using additional instruments such as complex problems, interview guidelines, and cognitive style questionnaires. The subjects of this research are 155 mathematics education students or preservice teachers then 7 preservice teachers who have a systematic cognitive style were chosen as the subjects. The result of this research includes 2 things. First, the stage of systemic thinking consists of 5 stages, namely the identifying stage, the investigation & classifying stage, the clarifying stage evaluating and justify-ing stage, and the reflecting stage. Second, the thinking process of preservice mathematics teachers who have s systematic cognitive style includes 5 stages. At the identifying stage, the preservice mathematics teachers identify information, processes and variables in a garment factory; and understand the objectives to be achieved from solving mathematical problems. At the investigation & classifying stage, the preservice mathematics teachers identify the key information, determine the production capacity of all lines; and determine the total order of t-shirts and jeans from 5 buyers. At the clarifying stage, the preservice mathematics teachers explain the system at the garment factory, and determine the sewing time provided by each buyer. At the evaluating & justifying stage, the preservice mathematics teachers can make various sewing schedules for each buyer, deter-mine the sewing schedule for 5 buyers where the time required to make the orders does not exceed 30 days, and determine the remaining production time so that it can be ensured that nothing is by R. At the reflecting stage, the preservice mathematics teachers review the sewing schedule that has been decided and revise the sewing schedule if there are mistakes. The findings in this research are the stages of systemic thinking and subjects with systematic cognitive style have detailed characteristics by paying attention to every aspect related to the problem as a whole and then breaking down into more specific matters in solving mathematical problems; and subjects with systematic cognitive style are able to produce many detailed and systematic solution options.
