Identifying Olympic Participants' Mathematical Reasoning Ability at Senior High School Level

IyayRobiaKhaerudin, Herri Sulaiman

Mathematical reasoning abilities are absolutely needed in solving non-routine mathematical problems and are often found in Olympic questions. In addition to extensive knowledge, talent and mathematical intelligence is one of the main factors that must be possessed in order to be successful in competing in the Olympics. The purpose of this study is to describe the level of mathematical reasoning ability in solving non-routine questions when competing in the mathematics olympiad. The method of this research is descriptive qualitative and the subject of this study is the Olympic participants who made it into the final round in the high school mathematics olympiad in West Java. Data collection techniques from this study are by giving tests, observations and interviews. Data analysis from this study starts from analyzing mathematical reasoning abilities from the results of written answers and participants' presentations in front of the jury, then continued with interviews to test the arguments and the breadth of mathematical knowledge the participants have. Furthermore, at the end of the study overall conclusions were drawn on the results of the mathematical reasoning abilities described. Strengthening conclusions is done by validating the results of the description associated with the theories and indicators of mathematical reasoning according to some experts. Based on the results of identification it can be concluded that the mathematical reasoning abilities of the Olympic participants have been seen but not maximized. One of the mathematical reasoning abilities that has been seen is to draw conclusions logically and some are able to provide a stage of explanation using models, facts, traits, and relationships. Whereas that has not been seen is the ability of participants to prove a characteristic or mathematical theory directly or indirectly. Thus, from this study can be used as an evaluation material for Olympic coaches to pay more attention to and provide non-routine questions in terms of developing mathematical reasoning skills when training Olympic students regularly in each of their schools.
