Research on the use Buzz Group method have been done to find outhow it affect the student achievement on the topic of colloid in class XI IPA SMA PGRIPekanbaru. This kind of research is experiment research with randomized controlgroup pretest-posttest design. The sample consisted of two classes, namely class XIIPA-1 as the experimental class and class XI IPA-2 as a controls class, it randomlyselected after normality test and homogeneity test. Experimental class is a class thatwas treated by learning using method Buzz Group, while the control class is a class thatis not treated using Buzz Group method. Data analysis technique is the t-test. Based onthe final calculation result obtained tvalue is 3,104 is greater than ttable is 1.67 with anincrease in the use of media influence a Buzz Groups method to student achievement is10,38%, so it can be concluded that the use of the Buzz Group method can improve thestudent's achievement on the subject of colloid in class XI Science high School PGRIPekanbaru

Penerapan Strategi Pembelajaran Active Knowledge Sharing untuk Meningkatkan Prestasi Belajar Siswa pada Pokok Bahasan Koloid di Kelas XI Sman 1 Kampar Timur

The purpose of this research to improve student achievement on the subject of colloid in class XI SMAN 1 Kampar Timur. Form of research is experiment research with pretest-posttest design. The sample consisted of two classes. Experiment class was given implementing learning strategies Active Knowledge Sharing, while the control class wasnot given implementing active learning strategies Active Knowledge Sharing. The t-test is used for data analysis technique. Based on the final results of data processing using t-test formula with dk=61 and ɑ=0,05 obtained Tarithmetic>Ttable (2.48>1.67) means that the application of learning strategies Active Knowledge Sharing can improve student achievement on the subject of colloid in class XI SMAN 1 Kampar Timur. Imporoved learning achievement because application of learning strategies active knowledge sharing thre student sued plays an active role in the learning process. Student can be seen from the liveliness of the willingness and aenthusiasm of the student in doing is student worksheet,discussion and knowledge sharing in problem solving with a group of friends or ather groups. Category Increased student achievement on experiment class including moderate with the normalized gain scores (N-gain) about 0,69

Pengembangan Media Pembelajaran Kimia Berbasis Autoplay Media Studio 8 pada Pokok Bahasan Struktur Atom

Research development of chemical-based learning media Autoplay Media Studio 8 is intended to produce a decent learning media on the subject of the atomic structure is developed based on the feasibility aspect of the display media, programming, content, presentation material content and language in Chemical Education Program. Beside that, it also to know the response of chemistry teachers and learners to media-based learning Autoplay Media Studio 8 has been developed on the subject of atomic structure. This media development research using ADDIE model of which has 5 stages of development, namely analysis, design, development, implementation and evaluation. Results of research-based instructional media development AutoPlay Media Studio 8 on the subject of atomic structures that have been validated by a validator to be feasible with an average percentage of 96.38%. Response chemistry teachers and learners expressed either by the average percentage of 98.2% for chemistry teachers and 91.89% for the learners. This indicates that the learning generated media fit for use as a medium of learning

Penerapan Model Pembelajaran Discovery Learning untuk Meningkatkan Prestasi Belajar Siswa pada Pokok Bahasan Koloid di Kelas XI IPA SMA Negeri 2 Tambang

The research aims to improve student learning achievementon the topic of colloid in XI science class of SMAN 2 Tambang by implementation of discovery learning model. The research is a kind of experiment research with pretest-posttest design. The sample consists of two classes, class XI science 3 as an experimental class and class XI science 4 as the control class is determined randomly after normality test and homogeneity test. Experimental class is a class that is applied of discovery learning while the control class was not. Data analysis technique used is the t-test. Based on data analysis of data obtained tcount>ttable is 3,52> 1,66 means that the implementation of discovery learning model can improve student learning achievement on the topic of colloid in XI science class of SMAN 2 Tambang. The result show that the average n-gain ternormalisasi in control class was 0,58 and eksperiment class was 0,75

Penerapan Model Pembelajaran Kooperatif Tipe Murder untuk Meningkatkan Prestasi Belajar Siswa pada Pokok Bahasan Koloid di Kelas XI IPA SMA Negeri 1 Kampar Timur

This study aims to determine Improved student achievement on thesubject of colloids with the implementation of cooperative learning model MURDERand the effect of the application of cooperative learning model MURDER to increasedstudent achievement on the subject of colloids in Class XI IPA SMAN 1 Kampar Timur.This research is a form of experimental research with the draft design randomizedcontrol group pretest-posttest. The study population was all students of class XI IPA atSMAN 1 Kampar Timur. The samples were students of class XI IPA 3 as experimentalclass and class XI IPA 4 as the control class. The experimental class was appliedcooperative learning model MURDER, while the control class using discussion method.Data were analyzed using t-test. Results from the study showed t count> t table (3.61>1.67) and the coefficient of influence by 17.33%, so it can be concluded theimplementation of cooperative learning model MURDER can improve the studentachievement on the subject of colloids in class XI IPA SMAN 1 Kampar Timur

Penerapan Strategi Pembelajaran Aktif Tipe True False Chain Untuk Meningkatkan Hasil Belajar Siswa Pada Pokok Bahasan Reaksi Redoks Kelas X SMA Negeri 4 Pekanbaru

An experimental research on the application of the active learning strategy typetrue false chain has been concluded to investigate the improvement of studentlearning outcomes on the subject of the oxidation-reduction reaction in class XSMA Negeri 4 Pekanbaru. From three classes of the population, it was taken twoclasses as the homogeneous samples, i.e. X.8 and X.7. The X.8 class was a controlclass in which they were used to teach by conventional teaching and learningprocess, while the X.7 class was taken as the experimental class in which theywere given the treatment of the active learning strategies type True False Chainimplementation. The data of the research was gathered by using testingtechniques, namely the pre-test and post-test. Before the pre-test and post-test, thesamples were tested by using a homogeneity test of homogeneity through T-test ofthe two parties in order to obtain two homogeneous classes. The difference inpretest-posttest values was analyzed by using two T-test samples of the party thataimed to test the truth of the hypothesis. Based on the results obtained bystatistical calculation that tvalue> ttable (2.070> 1.67), so it can be concluded thatthe application of active learning strategies type True False Chain can improvestudents\u27 learning outcomes on the subject of oxidation-reduction reactions inclass X of SMA Negeri 4 Pekanbaru
