Penelitian eksperimen semu ini bertujuan untuk mendeskripsikan keefektifan Pendekatan Saintifik, mendeskripsikan keefektifan Pendekatan PMRI, dan mendeskripsikan manakah yang lebih efektif diantara Saintifik dan PMRI ditinjau dari prestasi, minat, dan percaya diri. Populasi dalam penelitian ini adalah siswa kelas VII SMPN 2 Babadan Ponorogo Jawa Timur Indonesia dan secara acak terpilih kelas VIIB dan VIIC sebagai sampel. Teknik pengumpulan data adalah tes dan non-tes, dengan instrumen meliputi soal tes prestasi, angket minat dan percaya diri. Teknik analisis data menggunakan uji t dan Hotelling’s Trace. Hasil penelitian pada taraf signifikansi 0,05 menunjukkan bahwa Pendekatan Saintifik efektif ditinjau dari prestasi, minat, dan percaya diri. Pendekatan PMRI efektif ditinjau dari prestasi dan percaya diri, tetapi tidak efektif ditinjau dari minat. Saintifik dan PMRI sama-sama efektif ditinjau dari prestasi dan percaya diri, akan tetapi ditinjau dari minat Saintifik lebih unggul daripada PMRI.Kata kunci: pendekatan Saintifik, pendekatan PMRI, prestasi, minat, percaya diri The Comparison of the Effectiveness of Scientific and PMRI Approaches Based on the Achievement, Interest, and Self-Confidence of Students of Grade VII AbstractThis quasi-experimental research aims to describe the effectiveness of Scientific Approach, describe the effectiveness of PMRI approach, and describe which is more effective between of Scientific and PMRI Approaches in terms of the achievement, interest, and self-confidence. The population in this research were students of class VII SMPN 2 Babadan Ponorogo, East Java, Indonesia, and randomly selected VIIB and VIIC classes as a sample. The data collection techniques were a test and non-test, the instrument covers about mathematics achievement tests, questionnaires for students’ interest and self-confidence. The data were analysed using the t test and the Hotelling's Trace test. The results show that at the significance level of 0.05 the Scientific Approach is effective in terms of students’ achievement, interest, and self-confidence, while the PMRI Approach is effective in terms of learning achievement and self-confidence, but it is not effective in terms of interest. The Scientific and PMRI Approaches are equally effective in terms of learning achievement and self-confidence, but in terms of interest the Scientific Approach is superior to the PMRI Approach.Keywords: Scientific Approach, PMRI Approach, mathematics achievement, interest, self-confidence

This research aimed to prove the effectiveness of using animation movie in improving speaking ability of elementary students. The research was conducted in one class of the fourth grade with twenty-nine students and the selected samples were taken by random sampling. The data collection used an oral test as it is an experimental research by using T-test at 0.05 significance level. The results showed that the score of t-observation (to) was 9.43. Moreover, on the 0.05 significance level and with df n-1=28 the score of t-table (tt) was 1.70. It appears to  > tt  (9.43 > 1.70). It can be concluded that using animation movie in teaching speaking was effective for the elementary students. Benefits of the research result were by using animation movie the students could be more confident to speak with others because animation movies had interesting content that made the students interested to retell the animation movie with their own sentences. Therefore, they could be easier to make their own visualization with the movies which they had watched. However, it would be better if a language teacher gives many chances to practice in the classroom along with interesting media.

This study aims to describe whether there are differences in learning mathematics-based problem-solving in terms of results and student motivation of mathematics. This type of research is a quasi-experimental research and the design carried out on this study is a pretest-postest nonequivalent group design. In this research, the observation was done twice, before and after treatment. Observations made earlier are called pre-test and later observations are called post-test. The result of the calculation of the implementation of mathematics learning with the problem-solving based approach to student achievement is significant (p = 0,000 <0.05). It showed a Fcount of 1.002 <Ftabel of 1.76 with a significance level of 5%. Thus H0 is accepted and Ha is rejected, meaning there is a significant difference in mathematics learning achievement between problem-solving approach and conventional. The result of the calculation of the implementation of mathematics learning with the problem-solving-based approach to student's learning motivation is significant (p-count = 0.03 <0.05) or refer to Fcount of 1.07 <Ftable of 1.76 with a significance level of 5%. So that Ho accepted, it means there are differences in student learning motivation that is taught between using problem-solving based learning and conventional learning. Learning with problem-solving approaches will be effective if the teacher as an educator prepares the problems according to the context. From the results of this study, the researchers recommend being used as a reference for similar research with different subject materials. This research can be developed by adding other attribute variables such as student self-confidence, verbal ability, motivation, nor critical thinking ability.
