Abstract

The Implementation of Active Knowledge Sharing Strategies to Increase Students' Interest and Achievement Math High School of Tenth grade students of SMA PIRI 1 Yogyakarta in Academic Year 2013/1014. This research is Classroom Action Research (CAR) conducted collaboratively. The subjects in this study are The tenth grade students of SMA PIRI 1 Yogyakarta, amounting to 26 students. While the object is interested in mathematics learning and achievement gained from the application of Active Knowledge Sharing learning. The results showed that the interest and the achievement of learning math by using the Active Learning Strategies of Knowledge Sharing have increased. This is indicated by an increase in the average yield percentage interest in learning math sheet observation on Pre cycle 1 increased by 51.92% 62.18% in the first cycle and 78.21% in the second cycle. Interest in learning mathematics questionnaire sheet for each cycle, ie at pre cycle student interest at 63.28% increased to 72.47% in the first cycle, and increased in the second cycle becomes 84.37%. In addition, the average value of student achievement has increased the percentage pre cycle completeness of 55.15 with 23.08% (6 students) increased to 64.20 with the percentage of completeness 50.00% (13 students) in the first cycle, while the second cycle increased to 79.41 with the percentage of completeness 76.92% (20 students). Given the Active Knowledge Sharing strategy could increase interest and achievement of learning mathematics teachers should implement these strategies in teaching learning.

Abstract

kurangnya media penunjang pembelajaran matematika di sekolah/pesantren menjadi penyebab sulitnya pengkomunikasian pembelajaran matematika. Adapun alternatif untuk permasalahan ini adalah dengan menggunakan pendekatan saintifik yang berbantukan Geogebra. Dengan demikian, para santri akan lebih mudah dalam membayangkan materi dan mencerna pelajaran dengan baik.

Abstract

This research was formed the background by the low level of the studying achievement of the student's mathematics was caused by the negative perception of the student  towards mathematics, the object studying in mathematics abstract was not yet realistic and studying that was used did not yet use the teacher and the capacity of the study field to understand the concept of mathematics in the level was beforehand very weak. The aim of this Research was to know  that was effective used in studying, with team teaching  or individual teaching . This research used the method of the quasi experiment. The research population was all the student class X the Senior High School inYogyakarta in the year 2010-2011. The sample that was used in this research 2 schools. The taking of the Sample was carried out technically cluster random sampling. The instrument test was carried out used the validity test, the level of the difficulty of the difference power and reliabilitas. Technically the analysis that was used  t-test. As the condition for the analysis that is the population normal distribution, and the population had the same variance (homogeneous). In this research could be concluded that studying the team to the study field of mathematics not yet effective was applied to the student class X  the senior high school in Yogyakarta with the subject of discussion Trigonometry. This could be seen from results of the t-test that was received (tobs) of 1,145 where the area of criticism in u = 236 in the level siginificans 5% (two sides) is .

Abstract

The purpose of this research is to improve the activity and mathematics achievement of students of class VII with learning methods of problem solving in SMP N 1 Botodayaan, Rongkop, Gunungkidul. This research is Classroom Action Research (CAR). Techniques of data collection in this study was done by observation, documentation, and testing. Test instrument used to test the test item, whereas the observation sheet used to determine the level of involvement of the student. Data analysis techniques for observation sheet was conducted to determine student activity, whereas for mathematics achievement tests done by calculating the average value of the class. The results showed that after the application of the learning methods of problem solving, activity and learning mathematics achievement increased. It can be shown an increase in the average yield percentage of student activity sheets based on the observation that pre-cycle by 37.88% student activity, student activity first cycle of 51.01%, 76.77% for the second cycle. While the average value of student mathematics achievement increased from an average initial value of 56.97 to 66.16 in the first cycle and second cycle being 71.59. It is expected that schools can apply the learning method.
