This research aimed to identify the effect of POGIL model on the students’ mathematical problem-solving ability. The variables involved in this research were mathematical problem-solving abilities as an independent variable, and the POGIL model as a dependent variable. Based on the observations of researchers through interviews with mathematics subject teachers and students at Junior High School 2 Kalibagor, showed that the mathematical learning process that took place was still dominated by learning that did not involve the active role of students. The learning used is still teacher-centered and limited to information transfer, especially in the form of theoretical and mathematical equations. The population of this study was the students at seventh grade in Junior High School 2 Kalibagor, even semester in the school year 2017/2018 consist of 8 classes and amounted to 219 students. Sampling was done randomly, selected as an experimental class is 66.91 with 30 students and 55.91 as control class with 30 students. This test was validated by two mathematicians, then it was tested to a group of seventh-grade students to fulfill the validity and reliability criteria. The data were analyzed by using t-test after conducting a series of normality and homogeneity tests. It was concluded that t-test for equality of means was used for hypothesis testing that shows a significant value = 0.000 less than alpha 0.05. So that H0 is rejected, it means that students’ mathematical problem-solving ability taught by using POGIL model is better than students’ mathematical problem-solving ability taught by conventional learning. In other words, POGIL model influences or effects on students’ mathematical problem-solving abilities.

Social and economic inequalities have sharpened in the late 20 th century. During this period, Europe has witnessed a rising unemployment rate, a declining wages for the least qualified workers, a slowing of income growth, and an increasing gap between the richest and the poorest. Based on the hypothesis of the relation between socio-economic condition and mobility behaviour, it is necessary to ask how these socio-economic inequalities manifest themselves in transportation: does a rise in income inequality lead to a rise in transportation inequality and mobility practice inequality? This question is particularly relevant today as some European countries are facing high socio-economic inequalities following the financial crisis that started in 2008. Using results from transport, car ownership and mobility surveys as well as household surveys from the Paris (Île-de-France) region between eighties and late nineties, this paper tries to answer this question. The results show how inequalities in transportation and mobility practice have decreased during the period in spite of an increase in income inequalities. We find that the evolution of socio-economic inequality, most specifically income inequality was simply one of the determining factors of the evolution of inequalities in transportation and mobility practice. In fact, the most important role in that evolution is not played by the evolution of income inequality but by the evolution of elasticity between transportation and income. Reducing the effects of this elasticity should be the main target of transport policies to diminish inequality in transportation and mobility practice.

This study aims to determine whether the competences of Physical Education (PE) teachers make contributions to the quality of learning achievements of elementary school students. It was qualitative descriptive research using a reflective explorative approach. The subject of this study was the result of competence test of PE teachers in Yogyakarta Special Region in 2016. The study involved 60 PE teachers who were subjected to have an FGD (Forum Group Discussion) in some stages. The results show that the average score obtained by elementary school PE teachers in their Teacher Competence Test (TCT) stage II in 2016 was 61.79 for the pedagogical competences, and 60.07 for the professional competences. These results could exceed the national average score of 53.7. Based on the interviews with several teachers, the results of the competence tests had not indicated that PE elementary school teachers could improve the students’ learning quality. The teachers focused more on their preparations to take the TCT as a part of the assignments to the Learning Teacher program they participated in. This study also reveals that the TCT scores did not make a significant contribution to the students’ learning achievements in PE subject. Furthermore, TCT was considered by the teachers as a goal and not as an instrument to improve their competences in the teaching and learning processes.

Sementara itu, langkah-langkah yang hendak diterapkan dalam metode analisis data berturut-turut berupa, (1) klasifikasi data; (2) display data; (3) melakukan  penafsiran dan interpretasi serta pengambilan kesimpulan. Guru PJOK di Daerah Istimewa Yogyakarta masih terkendala oleh kapasitas IT, kejelasan program Guru Pembelajar serta rendahnya pendampingan dari instansi terkait, sehingga dalam melaksanakan program ini mereka mengalamai stagnasi. Community based learning menjadi metode yang diingini oleh para guru PJOK dalam mengembangan kompetensinya. Konsep The Five Disciplines dari Peter Senge yang meliputi personal mastery, mental models, building shared vision, team learning, dan system thinking perlu didorong dalam upaya menghebatkan para guru PJOK. Needs analysis for the sport and health education teachers after the implementation of learning-teacher program AbstractThe study aims at mapping the in-depth and concrete teacher competence and recommendation formula toward the concept of effective, efficient, productive, creative and innovative job implementation in implementing the special program of teachers’ competence and professionalism development in the Province of Yogyakarta Special Region. The study is a qualitative descriptive research with explorative-reflective nature. When the study was conducted, the subjects were 30 teachers of Sports and Health Education in the Elementary Schools degree throughout the Province who had been selected by means of purposive sampling technique. Then, the data in the study were gathered bt means of identification or record sheets. After the data had been gathered, a focus group discussion (FGD) was conducted by involving several teachers who had also been selected by means of purposive sampling technique. Then, in analysing the data for the study the following procedures were applied: (1) data classification; (2) data display; (3) interpretation and conclusion drawing/verification. Based on the results of the study, it might be concluded that the teachers of Sports and Health Education in the Province of Yogyakarta Special Region are still troubled with their capacity of operating Information Technology, the clarity of Learning-Teacher Program and the low guidance provided by the relevant institution; as a result, the implementation of the program among the teachers become stagnant. The teachers in the program prefer Community-Based Learning as the method for the program implementation. In relation to the demand, the concept of Five Disciplines by Peter Senge that includes personal mastery, mental models, building shared vision, team learning and system thinking should be encouraged in empowering the teachers of Sports and Health Education.
