The aim of this study was to determine the effect of the use of learning methods Team Assisted Individualization (TAI) on learning outcomes of students' mathematics class VII MTs NW Montong Baan academic year 2014/2015. This type of research is experimental research, form design used was nonequivalent control group design. Sampling was done by purposive sampling technique. The sample in this study amounted to 39 students for the experimental class, and 38 students in the control class. Data in this study were drawn by providing initial test and final test to students in grade samples. Data collection techniques using objective tests that have been tested for validity and reliability by the validator. Data were analyzed using t-test. From the result of the calculation, shows that student learning outcomes group teaching methods Team Assisted Individualization (TAI) was higher than the control group, the t test results are known thitung 2,392 and ttabel 1,995 at significant level of 5% by dk = 75 because thitung > t table (2,392> 1,995), the Ha accepted and H0 is rejected, which means learning methods Team Assisted Individualization (TAI) effect on learning outcomes mathematics class VII MTs NW Montong Baan school year 2014/2015.

Teachers are professional educators with the primary task of educating, teaching, guiding, directing. train, assess, and evaluate students. Conducting an assessment and evaluation of learners have strategic value because the result can be a material reflection for designing learning mathematics teacher quality. Identify the problem through a questionnaire distributed to students who have carried out Practice Field Experience shows that they still have weaknesses when assessing the understanding of mathematical concepts, procedural knowledge, and problem solving skills. The main obstacle is not available adequate teaching materials for studying these three aspects, necessitating an effort to develop a module for evaluation of learning mathematics courses. The module was developed with the problem solving approach through three stages of adaptation of the model development by Thiagarajan 4D, which define, design and develop. The results of the validation by the two experts of module design are extremely valid with a score of 82.963%, and 91, 852%, and the results of the validation by the two experts of creative content is also very valid with a score of 87.143% and 95.714%. In addition, the result that the use of the modules have an impact on student learning outcomes at tcount = 17.09765>ttable = 2.02439, df = 36, and = 5%. So we concluded that the evaluation of learning course modules that have been developed have valid, practical, and effectivecriteria.

The purpose of this study was determine the effect of application of lattice multiplication method to overcome the difficulties of completing mathematical multiplication and anxiety operations in grade VIII of SMPN 7 Pujut. The method used in this study was pre-experimental research method with one group pre and posttest design research design. The sample of this study was representative of students from each class in grade VIII of SMPN 7 Pujut, it was recommended by mathematics teachers because they had difficulty completing multiplication operations, about 20 students. Based on the results of the study, the mean difference in the percentage of the initial results mathematical anxiety questionnaire with the final result was from 56.37% decreased to 42.65%, which were both still in the sufficient category. Furthermore, by testing the hypothesis using the t test (paired sample t test) assisted by SPSS 16.0 obtained data tcount = 0,000 and with a = 5% = 0.05 obtained ttable = 1.729 which means tcount ttable. These results indicate that there were significant differences between the results of the test before applying the lattice multiplication method (pretest) with the results after the application of the lattice multiplication method (posttest) obtained by students. Thus it can be concluded that there was a rejection of H0 so that Ha is accepted, where Ha reads: there was an effect of the application of lattice multiplication method to overcome the difficulties of completing mathematical multiplication and anxiety operations in grade VIII of SMPN 7 Pujut.

Penyebab rendahnya pemahaman siswa terhadap pembelajaran matematika sangat dipengaruhi oleh beberapa komponen pembelajaran meliputi guru, siswa, strategi dan media yang digunakan dalam pembelajaran. Pembelajaran yang digunakan di MTs NW Montong Ba?an masih cendrung berpusat pada guru sebagai sumber belajar, sehingga komunikasi yang terjadi hanya satu arah. Akibatnya pada proses pembelajaran siswa kurang aktif, kurang berminat dan mudah bosan, siswa cendrung belajar secara mekanistik, interaksi kurang, belajar dengan cara menghafal tanpa memahami makna yang sebenarnya, dan motivasi untuk belajar kurang. Pembelajaran multimedia merupakan komponen system penyampaian pengajaran yang dapat digunakan dalam mendukung proses pembelajaran. Proses pembelajaran yang efektif terletak pada optimalisasi beban kognitif dalam kapasitas memori kerja siswa yang terbatas. Dalam mendesain pembelajaran perlu mempertimbangkan faktor beban kognitif. Pembelajaran yang efektif dapat dicapai dengan mengelola beban kognitif intrinsik, mengurangi beban kognitif asing, dan meningkatkan beban kognitif erat. Semakin banyak pengetahuan yang dapat digunakan secara otomatis dalam proses pembelajaran maka semakin minimum beban kognitif di memori kerja. Penelitian ini bertujuan untuk mendeskripsikan pembelajaran multimedia berdasarkan teori beban kognitif pada materi lingkaran yang dapat meningkatkan pemahaman siswa kelas VIII MTs NW Montong Ba?an. Jenis penelitian ini adalah penelitian tindakan kelas (PTK) yang dilaksanakan dengan alur yang berulang (siklus), yang terdiri dari 4 tahapan yaitu perencanaan, pelaksanaan tindakan, observasi, dan refleksi. Hasil penelitian menunjukkan bahwa pembelajaran multimedia dapat meningkatkan pemahaman konsep siswa berorientasi pada beban kognitif dengan siklus I mencapai 70,69 dari 36 siswa dan yang tuntas sebanyak 28 orang atau ketuntasan belajar mencapai 77,77 % dan siklus II mencapai 75,83 dan ketuntasan belajar siswa sebesar 88,88% dengan kategori aktivitas belajar siswa ?Sangat aktif?.
