Pengaruh Strategi Pemecahan Masalah Wankat-Oreovocz dan Pembelajaran Teknik Probing terhadap Kemampuan Literasi Matematis Siswa SMP
Full text linkLow of mathematical literacy become this research base. Alternative solution in overcoming the problem is needed absolutely, so this research aim to analyze the essence of learning the strategy of Wankat-Oreovocz problem solving and the Probing Technique learning as alternative the problem solution. The research design which is used is a non-equivalent control group design by using technique of Purposive Sampling. The Research Subject is all eight grade students of Sukahaji Junior High School with the research sample is eight grade students. The research instrument used in the form is mathematical literacy test of level 5, teaching materials and questionnaire. Result of the research indicates that: There is not the difference of mathematical literacy of level 5 at student who is getting strategy of Wankat-Oreovocz problem solving (WO) and the Probing Technique learning (TP
Efektivitas Model Pembelajaran Think-Talk-Write dalam Meningkatkan Komunikasi Matematis Mahasiswa Pendidikan Matematika
Full text linkThis research has aims to determine the effectiveness of learning model Think-Talk-Write (TTW) and determine whether the learning TTW modelis more effective than conventional learning to improve student mathematical communication. The research is a quasi experimental research. The populationin this research were all students ofthe second semester in Mathematics Education department. They are divided into four parallel classes. Samples were IIA2 class as the control class and the IIA1 class as a class experiment in Number Theory lesson. The instrument in this researcsh was test of mathematical communication. The analysies of data use SPSS 16, the proportion test of one population, and t test. The hypotesis tests use the proportion test of one population and t test. Based on the results of this research were concluded that : (1) The mathematical learning by learning model Think-Talk-Write is effective to improve the mathematical communication students. It can be proved fromthe results of proportion testonan experimental class of mathematical communication valueis 1.87 > z table with a significance level 5%. Z table is 1.64. (2)The learning model Think-Talk-Write more effective than conventional approaches. It can be proved from the results of t test. The value of mathematical communicationis 2.07 >t table with a significance level 5%. t table is 1.67
EFEK LESSON STUDY TERHADAP PENINGKATAN KOMPETENSI PEDAGOGIK CALON GURU
Full text linkThe aims of this research was to know difference increasing especially ability in Plan and Do between lesson study-based learning and not(conventional) learning. Furthermore, the second aim was to know the effect of lesson study toward increasing of pedagogy competency and impact of prospective teachers in teaching. The methodology of this research was using descriptive qualitative with amount of prospective teachers is 13, then the prospective teachers conducted Plan and Do respectively 3 times meeting using lesson study and conventional. The results showed that the effect was very positive where the learning process of Plan and Do using lesson study was better than conventional learning. Besides that, based on the observation and valuation showed that lesson study-based learning was better than conventional learning. The effect could also influence for students and prospective teacher positivel
