Abstract

Mathematical investigation is an activity that can encourage an experimental activity, collect data, make observations, identify patterns, make and test conjectures and make generalizations used to improve skills and develop students' mathematical thinking processes optimally. Different cognitive styles can affect students' ability to think and reason, especially in solving mathematical investigative problems. Therefore, this paper will examine mathematical investigations' ability in reflective and impulsive cognitive styles in qualitative descriptive analysis. The subjects in eleventh-grade senior high school at SMA Negeri 2 Mataram, Indonesia. Students were selected using a purposive sampling technique, and six students were selected as subjects in the interview consisting of three reflective students and three impulsive students. The instruments used are mathematical investigation tests, Matching Familiar Figure MFFT tests, and interview guidelines. The results showed that students with a reflective cognitive style were more thorough and systematic in writing down the answers to each point and always thought first in solving problems. Most students went through 4 stages of mathematical investigations: specialization, conjecture, generalization, and justification. While students with impulsive cognitive styles mostly managed to go through 3 stages of mathematical investigations, specialization, conjecture, and generalization, due to a lack of accuracy in solving questions and providing as simple answers as possible according to the question request.

Abstract

Utilization of technology, information and communication, especially the use of software such as Microsoft Word, Microsoft Power Point and Microsoft Excel is an ability that must be possessed by elementary school teachers in implementing an independent curriculum. The use of Microsoft Excel, for example, can assist teachers in processing various data, such as processing assessment instruments in the form of end-of-semester assessment questions for students. Based on interviews with the group leader V Lingsar, the results showed that teachers still needed time in making final semester assessment questions, starting from making question banks, sorting and randomizing questions into several question packages. To answer these problems, a service activity was carried out in the form of training on the use of Microsoft Excel to create a question bank. The training was attended by 20 teachers of the V Lingsar group. This activity consists of two sessions, namely the delivery of material and guided practice. All participants felt that the material could be understood well, guided practice could be carried out smoothly and this activity could be relevant to the needs of the teacher.
