This research describes the knowledge and beliefs of pre-service teachers about mathematics. Data collection of this research using written test of 143 mathematics pre-service teachers who have taken six semesters at Universitas PGRI Semarang, and interviewing of three pre-service teachers who are not consistent between knowledge and belief. The data are presented in the form of descriptive quantitative and analyzed qualitatively, including data reduction, data display, and conclusions drawing/verification. The results show that most of the knowledge of pre-service teachers are consistent with their beliefs. It is indicated that pre-service teachers’ knowledge has been internalized into a strong belief that affect their words and behaviors. The belief of almost half of pre-service teachers who become respondents changes because of lecturer activity effect. It can say that belief changes at any time, both the process of alteration and the formation of new beliefs as well as the reinforcement of the beliefs they have.

Ethno-mathematical research trends pioneered by D'Ambrosio are on the rise, especially in Indonesia as a nation with high cultural diversity which has a lot of potential researches to be explored. This paper has two major objectives, first to explore the importance of the role of mathematics in the practice of Dhikr Jahar in Tariqa Qodiriyyah Naqsyabandiyyah and second to contrast the differences between mathematical phenomena and mathematical concepts in ethnomathematics research. Attempts to contrast the mathematical phenomena and mathematical concepts in ethnomathematics was expected to provide a sharper highlight in the writing of ethnomathematics research. This research used qualitative methods with two approaches, namely ethnography and phenomenology. The locations of the research are at Pondok Pesantren Suryalaya-Sirnarasa and Padepokan Talangraga Tasikmalaya with observations for 9 months in the first stage and then 6 months in the second stage. The number of respondents interviewed in this research were 48 people. Data processing was performed using the Nvivo 12 Plus. The results showed that there are many mathematical phenomena in the practice of Dhikr Jahar Ikhwan TQN. In carrying out the practice of dhikr, the Ikhwan used a mathematical concept with two events, fingers and prayer beads aids. The concept of counting in dhikr was used strictly by the Ikhwan. They believe that numbers have an important role in the quantity of dhikr. Contrasting mathematical phenomena and mathematical concepts can be done with an emic and etic approach and is expected to become an alternative style in ethnomathematics research.

The purpose of this study was to determine the increase of students' creative thinking, which taught using problem-based learning with local culture (PBL-Local Culture). In this study also saw the interaction between students' gender and students' prior mathematics ability. This type of research is quasi-experiment research, using pre-test post-test control group design. Data were analyzed using SPSS 25 through Two-Way ANOVA. The result shows that increasing the creative thinking abilities of students taught using problem-based learning with local culture is significantly higher than the creative thinking abilities of students taught using classical learning. Based on the result, we found that the use of problem-based learning local culture (PBL-Local Culture) offered the opportunity to give student new experience to solving real problems in their daily life, primarily related in their local culture. Students can describe how to solve the daily life problem with mathematically modelling. This learning model has given the facility to students at the end to improve their creative thinking ability. Students make the new model of problem-solving and finally they can solve that problem with their model. This study also found that the factor of students' gender and students' prior mathematics ability has not given the effect of students' creative thinking ability. It means that there is no gap in gender and the contribution of students' prior mathematics ability in students' academic skills. Based on this study, we recommendation of this model to using in other subjects in the learning class and to improving other learning ability, not limited in creative thinking ability.

Structural Equation Model (SEM) was known as powerfull and popular multivariate analysis technique. It provides a comprehensive method for the quantification and testing of theories. The ability of this model is to test model with multiple dependent that more powerfull than multiple regression, it’s also can make some simultaneously model in one form. Data was used from Holzinger and Swineford that measured intellegence in several indicator. This model was lack of form and performance that can be showed in value of Chi-square. Akaike Information Criterion (AIC) and Chi-square value for specificly in block “male” was less than “female”, so the result gave structural model for block male was better than female.
