Full text linkUsing Multimedia in Learning Kinetic Gas Theory in SMA / MA Public and Private District of Sambas. This study aims to see changes in student learning outcomes after learning using multimedia by comparing the value of the learning outcomes of the pre-test and post-test. Quasi-experimental methods used in this study with one group pretest-posttest design. Research subjects choose three of four SMA/ MA Public and Private District of Sambas which has a program of Natural Sciences, SMA Negeri 1 Sambas (20 students), MAN Sambas (19 students), and SMA Santo Bonaventura (16 students). Based on the data analysis and discussion, the average percentage of learning outcomes pre-test on Gas Kinetic Theory of 53.68% of the 55 students. While the average percentage of learning outcomes post-test 69.04% of the 55 students. The increase in the average percentage of student learning outcomes in the material Kinetic Theory of Gases using multimedia for 15.37%. The results of calculations using the McNemar test, of the total ten questions occur to improving student learning outcomes Gas Kinetic Theory of matter between before and after learning using multimedia, which calculate the average X2 mean = 9.10 and X2table mean = 3.84 this means that the calculated X2hitung > X2table.

PENINGKATAN PEMAHAMAN SISWA PADA MATERI KOLOID MENGGUNAKAN PEMBELAJARAN MODEL SIKLUS BELAJAR 5E KELAS XI SMAN 2 PONTIANAK
Full text linkThe purposes of this study are 1) to determine difference of conceptual understanding of SMA 2 Pontianak students before and after being taught through 5E learning cycle model on colloid subject matter, and 2) to describe conceptual understanding of SMAN 2 Pontianak Students before and after being taught through 5E learning cycle model on colloid material. This study was conducted in form of pre experimental design. Independent variables were learning before and after being taught through 5E learning cycle model. Dependent variable was students conceptual understanding. To collect data, assessment technique was applied and achievement test was used to get data. Data were analyzed by means of inferential and descriptive statistic. Result of statistic showed P-value = 0,000 < α = 0.05 which means that there was a difference of students conceptual understanding before and after being taught through 5E learning cycle model on colloid subject matter. Improvement of students conceptual understanding was 0,31 which means on average level. Key words: conceptual understanding, 5E learning cycle model

Full text linkThis research is aimed to determine the effectivity of cooperative learning model through Numbered Heads Together (NHT) by visual media on students’ achievement in material life organization of VII grade SMP Rehoboth. The research is quasi experimental design, with nonequivalen control group design. The research samples are VIIa and VIIb grade. The technique of data collecting is by using random sampling. The average score of the students’ achievement that has been teach by using Numbered Heads Together (NHT) of cooperative learning model with visual media is 14,89 as higher than the conventional model of 11,29. The t-test in standard 5% shows tcount= 5,023 bigger than its comparation to ttable = 1,679, it means there is a significant difference in the post-test result. The counting of effect size is 1,27 it includes high, so the concluded that Numbered Heads Together (NHT) of cooperative learning model with visual media gave 39,80% of contribution on students’ achievement.Key words : Numbered heads together, visual media.
PERANAN NUMBER HEADS TOGETHER DALAM PEMBELAJARAN BIOLOGI DI KELAS XI IPA
Full text linkThis research motivated presence of symptoms that can be seen in the field that the biological activity and learning outcomes have not achieved the expected result of 78. The cause of the low biological activity and learning outcomes is presumably because the teacher actively describes the material, give examples, and exercises while students just listen, take notes, and do the exercises. Learning as it failed to give students the chance to discover, establish and develop his own knowledge. This type of research is done in an attempt repair of the problems mentioned above is a Classroom Action Research. Data of this research is taken using an instrument tests, observation sheet and evaluation test results are processed in a qualitative study. The results showed that by using cooperative learning type Number Heads Together can increase the activity of learning and learning outcomes of students of class XI IPA1 SMA 4 Pontianak. Keywords : Activity, learning outcomes, Number Heads Together
