Students' low mathematical communication skill is influenced by several factors such as learning models applied by teachers in the classroom and the students' learning motivation. Advanced organizer Model is appropriate to improve the students' low ability. This study aims to determine whether: (1) there is an influence of advance organizer model toward the mathematical communication skill; (2) there is an influence of learning motivation toward the students' mathematical communication skill, and; (3) there is an interaction between learning model and motivation toward mathematical communication skill. This research employs quasiexperimental design and the statistical analysis used is the two-ways variance with unequal cells. The result of this research shows that:(1) there is an influence of advance organizer model toward mathematical communication skill; (2) there is an influence of learning motivation toward students' mathematical communication skill, and ; (3) there is no interaction between learning model and motivation toward mathematical communication ability.

The ability to understand a concept in the learning of mathematics is something that is required by each learner. But in fact show that in the learning process, teaching materials used have not trained learners in doing a discovery and learners less active in the learning process. This study aims to produce teaching materials in the form of a didactic design module teaching materials Algebra on Mathematics Subjects for Class VIII Semester 1 Subject material Algebra in SMP Negeri 1 Pakuan Ratu. The teaching materials module with didactic design is a module in the form of a learner's guide which contains information, materials about Algebra, examples of problems as well as exercise questions, in accordance with the problems that natural learners on learning materials, this instructional material is made to petrify participants educated in solving problems on Algebra material. Based on the results of research, Didactic instructional materials developed by researchers deserve to be used according to the validation results of material experts, linguists, education practitioners, media experts, and help learners to learn more independently and comfortable in the learning process as well as learners are very interested in teaching materials (modules) of this didactic design.

The ability of adaptive reasoning is a competence that must be possessed by students, but the reality of the field shows that students' adaptive reasoning ability is still not satisfactory. Learning with the accelerated learning method is applied in the hope of improving students' adaptive reasoning abilities. The purpose of this research is to know whether the improvement in students' adaptive reasoning ability with accelerated learning method is better than ordinary learning. This research is a quasi-experiment or quasi-experiment with pretest-posttest control group design. Implementation of this research is done on grade VIII students in one of the State Junior High School in Bandar Lampung. Problems given are questions of reasoning ability of adaptive in material relation and a function, test of ability, ability of reasoning is tested theoretically by validating with picture that test question can be well understood and empirically validity and reliability fulfill characteristic to be used in research, The degree of difficulty and distinguishing power of the problem can already be used to determine the enhancement of the ability of adaptive reasoning. Quantitative data analysis was performed using flat most different and N-Gain test. The results of this study are students whose learning to apply learning with an accelerated learning method of enhancing the ability of adaptive reasoning is significantly better than that of students whose learning using ordinary learning is reviewed in whole.

Hypothesis testing conducted in this research uses two-way ANAVA with ∝=5%. The results showed: (1) learning using TAPPS type cooperative learning using gamification teaching materials is more effective than learning with conventional methods, (2) there is a self-confidence effect on mathematical reasoning abilities, high Self Confidence is better than medium and low self-confidence and the ability of mathematical reasoning with medium Self Confidence is better than low Self Confidence, (3) there was no interaction between TAPPS type cooperative learning and Self Confidence in mathematical reasoning abilities.   Penelitian ini bertujuan untuk mengetahui apakah terdapat pengaruh antara penerapan cooperative learning tipe TAPPS  menggunakan bahan ajar gamifikasi dan pembelajaran konvensional, perbedaan antara kepercayaan diri yang tinggi, sedang dan rendah, dan  interaksi antara cooperative learning tipe TAPPS dan kepercayan diri terhadap kemampuan penalaran matematis siswa SMP. Jenis penelitian in adalah Quasy Eksperimental, Penelitian dilakukan di SMP Negeri Natar Lampung Selatan dengan jumlah siswa 64.  Sampel kelas yang digunakan adalah dua kelas dengan menggunakan teknik Cluster Random Sampling. Pengujian hipotesis menggunakan ANAVA dua arah dengan ∝ = 5%.
