Abstract
Study This aim For analyze acquisition And enhancement Ability Communication Mathematics (KKM) for junior high school students learning material get up room use approach Problem Based Learning (PBL) with help Geogebra and learning Direct Instructions with help Geogebra. Study Also consider factor level independence learning (TKB) students in study impact second the approach. Method research used is quasi-experiment with design pretest-posttest and group control, involve two group treatment. The undergoing group learning with PBL approach with help Geogebra and following group learning Direct Instruction with help geogebra. Student in study this shared based on level independence study them. Data collected through test initial (pretest), implementation learning, and test final (posttest). Data analysis involves comparison between improvement of students^ KKM before and after treatment in second group treatment, as well the effect of TKB on improvement of KKM. Results study show that second approach learning contribute on improvement of students^ KKM on material get up space. Although thus, the group that followed learning assisted PBL approach Geogebra show more improvement significant compared to with group learning Direct Instructions help Geogebra. Besides it is identified that TKB students affect results improvement of KKM, where student with high TKB tend more get benefit from assisted PBL approach Geogebra. In framework improve students^ KKM in learning material get up space, recommended for educator for consider use of assisted PBL Geogebra as well as notice level independence study student in designing strategy effective learning
