Women's leadership in the education sector began to show a rising trend. This is because the glass ceiling barrier that has been turned into a maze, where more women to contribute at the leadership level, is one of the leaders in schools with special needs. Schools with special needs are schools that serve education for individuals who have differences. All children with special needs have the same rights in their needs education, where they need education more participatory and collaborative, as well as various studies that have been done are more feminist leadership characteristics. This article will discuss the leadership styles of women in special needs schools in Jember, especially in facing the challenges of the 21st century skills. This study uses qualitative research methods with engineering data in the form of in-depth interviews, observation, and documentation. Data analysis includes data reduction, data presentation, and conclusion reduction. Research informants for people who are principals in special needs schools in Jember.. The results showed that the leadership style used by female leaders in schools with special needs in Jember Regency was more to involve relational or transformational, where leadership was built on the basis of communication, relationships, and teamwork, but among these were specific instructional leadership strategies. Women leaders to pay more attention and mentoring and encourage appropriate behavior, both with teachers and students with special needs in their schools. The results of this study can be used by feminist leadership with the characteristics of caring, visionary, collaborative, courage, and intuition.

Indonesia's inVolvement in international tests, one of which PISA (Program for International Student Assessment), shows that Indonesia learners are less capble of using mathematical concepts to solve problems associated with real life. This is because these students tend to be taught practical formulas that will be used to answer questions in the exam. This research aimed at describing ethnomathematics in some Balinese cultural elements; ceniga, the yard size based on asta kosala-kosali, and also the pattern of Legong dancer position. Those three cultural elements were used because it is appropriate with plane figure geometry material for seventh grade students and further it is hoped to create ethnomathematics-based geometry problems. This research was a descriptive qualitative. The data were collected by conducting Balinese culture based geometry test to know the seventh grade students' logic and mathematics reasoning ability that had been chosen as the subject of the research based on the performance rubrics. The results of research show that there are significant mathematical abilities of students to logic and reasoning in solving geometry-based culture of Bali.

This research aimed to produce natural science learning material based on Ploomp theory for Junior high school students. The learning material in this research was a book which was integrated with islamic values and satisfied validity, practicality, and effectiveness. Besides, the researchers also convinced that those criteria, validity, practicality and reliability, appropriate to students' test answer. The subjects of this research were 15 of eighth grade students of Madrasah Tsanawiyah (MTs) Darul Hidayah Wuluhan Jember, east Java Indonesia. The methodology on this research was adapted from Ploomp theory. The validity product of this learning material could be shown by the expert validity. This can be reached when the expert said that it was valid for both the book and the test sheet. The practicality of the book must reach very practical criteria. This was based on how practical teacher delivered the material and how students understand the material. The effectiveness of the product could be shown by students' attitude in learning activities, cognitive skill, and well-skilled in psychomotor. The learning material was said valid because the validators said that those instruments were valid. Validator scored the learning material (book) as 3.3 (4 scales), and test sheet as 3.58. Hence, those learning materials can be said valid. Secondly, the learning materials was practical because the validators said that the book can be used with minor revision and students learned the material actively. The learning materials called effective as well, because satisfied two indicators of effectiveness, which were students' response about learning activity was positive with 82.21% students answered so, and the result of the test was said valid because reached minimal score of 0.73 and reliable about 0.57.

Naïve Bayes Imputation (NBI) is used to fill in missing values by replacing the attribute information according to the probability estimate. The NBI process divides the whole data into two sub-sets is the complete data and data containing missing data. Complete data is used for the imputation process at the lost value. The process is repeated for each missing attribute to generate complete data for classification. This research applies NBI for imputation and preprocessing as preparation of classification process. The trial of this study used NBI for imputation compared to using the mean and mode to predict the missing data. The data used for imputation is full train of complete data as a whole to predict the missing value so as to represent the entire data. The results of this study prove that imputation with NBI produces the right imputation with higher accuracy than other imputations. NBI with single imputation and multiple imputation results in better performance because of the right features. This study aims to calculate the effect of missing values on Naïve Bayes Imputation Algorithm is based on a probalistic model using mixed data. Empirically shows that the interaction between several methods of imputation and supervised classification results in differences in the performance of classification for the same imputation method.

This study aims to describe the increase in Elementary School students' reasoning ability in solving mathematical problems using the OSCAR learning model and responses students. The OSCAR model was developed by researchers in 2017. The OSCAR model based on the Problem Based Learning (PBL) model and several learning approaches such as Realistic Mathematics Education (RME) and Contextual Teaching and Learning (CTL). The difference between OSCAR and PBL lies in the Self-observation phase. This phase gives students the opportunity to observe problems individually before being discussed in groups. This model consists of five phases, namely Orientation, Self-observation, Construction, Association, and Reflection. The research used quasi experimental method with the one group pretest-posttest design. The instrument that used are mathematical problem solving test and student response questionnaire. The subject of this research is the V-B grade students of SDN Sidotopo Wetan I Surabaya in 2017/2018. To see the increase in student reasoning ability is to calculate the N-gain index. The calculation result of the N-gain reasoning score has an average 0,40. This shows an increase.The results of the analysis on students' responses showed an average of 99,66% of students happy about the subject matter, work-sheet, exercises, and how teachers teach.
