Eksperimentasi Problem Based Instruction (PBI) DenganudOpen Ended Dan Closed Ended Ditinjau Dari KemampuanudAwal Terhadap Prestasi Belajar Pada Materi LingkaranudSiswa Kelas VIII Semester Genap SMP Negeri 1 SukodonoudTahun Ajaran 2014/2015

摘要

The purpose of the research are to analysis: (1) contribution problem basedudinstruction with open ended and closed ended direct learning in mathematicsudachievement (2) contribution prior knowledge direct learning in mathematicsudachievement (3) interaction problem based instruction with open ended and closedudended in terms of prior knowledge direct learning in mathematics achievement.Theudresearch used quasi experimental method. The population of this research was all ofudthe class VIII student at SMP Negeri 1 Sukodono regency on academic yearud2014/2015. The sample of research were by using the stratified cluster randomudsampling. The sample were used consist of two classes, which VIII A as experimentaludclass 1 and VIII C as the experimental class 2. The collection data was conduted byudtest. The technique of analysis data consist of conditional test and hipotesis test.udConditional test consist of normality test, homogeneity test and t-matching test. Theudhypothesis test used unbalance two ways analysis of variance. From The Analysis, itudis found that :(1) There was contribution problem based instruction with open endedudand closed ended direct learning in mathematics achievement (2) There wasudconstribution prior knowledge direct learning in mathematics achievement (3) thereudwas not interaction problem based instruction with open ended and closed ended inudterms of prior knowledge direct learning in mathematics achievement
