Abstract
Related to face the era of globalization where job competence requires someone who is critical, creative, able to work together and able to communicate, learning does not only lead to the provision of knowledge but training skills become important. We call this skill a 21st-century skill (KA21). The quasi-experiment study with 100 samples taken randomly from 288 populations in one of the high schools in Bandung Regency aims to get an overview of the development of the KA21 through the application of IPjBL with a reading infusion strategy and google classroom. The development of KA21 was measured using the rubric adopted and adapted from the Boss and analyzed using the standard developed by Lati, which has been tested with inter-rater reliability technique with the reability of 0.67. The results of the study show the experimental class critical, creative and collaborative thinking skills can increase to good level and communication skills to excellent levels. In the control class, critical thinking skills and creative thinking skills can increase to good level while collaboration and communication skills increase to excellent levels. The conclusion of this study, learning needs to be developed to get wiser ways to train KA21.

Abstract
Generative and Connecting, Organizing, Reflecting, Extending (CORE) are two sets of learning design that can develop learners- critical thinking skill. The objective of this study was to point out the best model to develop learners- critical thinking skill. For this objective, a quasi-experiment was done in 12 Jakarta Senior High School. Two groups of eleventh grades learners were elected by random sampling method. Generative learning was applied to the first group, while CORE learning was applied to the second group. Learners- critical thinking was regulated by the test which produced based on critical thinking skill indicators. Before starting the program, each group took an initial ability test. The program lasted for four weeks, and four hours each week; and at the end of the program post-test works were taken from the candidates. The hypothesis was tested using independent sample t-test with a probability of significance value of 0.05.The results of the research shown that there was a significant difference between the t-test score points of the experimental groups (P<0.05) namely t-count = 3,092 > t-table = 1,667. The results also showed that the average of learners- critical thinking skill points with generative learning model was higher than the other group. It was observed that this paper previously uncovered a role for (1) Barbara L. Grabowski (2014) that generative learning model can increase critical thinking skill and (2) Robert C. Calfee (2004) that CORE can increase critical thinking skill. This manuscript builds on our prior study to compare both models and focus on the effects on critical thinking skill.

Abstract
Early algebraic thinking was not explicitly mentioned in the elementary school mathematics curriculum in Indonesia. However, whether students are able to develop important algebraic ideas from a general arithmetic perspective through the current curriculum. This study tries to explore the learning experiences of elementary school students and constructs the meaning behind these learning experiences towards the emergence of early algebraic thinking. The researcher analyzes how students construct meaning through in-depth interviews with students in grades IV to VI. The results of this study indicate the fact that certain algebraic ideas must be deliberately reformed in the curriculum since the early grades, because these ideas did not develop naturally in students without proper learning design.

Abstract
The purpose of this study was to find out the alternative conceptions of high school students related to concepts in the subject matter of simple electric circuit. The concepts reviewed include the concept of electromotive force (emf), the concept of electric current and the concept of electrical resistance. This research was conducted using quantitative descriptive methods. The number of research subjects was 36 students consisting of 20 female and 16 male, in one of the high schools in the West Bandung district of West Java province. Data were collected by conception test in the form of open essays test related to concepts in the subject matter of simple electric circuit. The results showed that the number of alternative conceptions that high school students had that emerged on each concept were: 1) There were three (3) alternative conceptions that emerged in the concept of electromotive force; 2) There are four (4) alternative conceptions that arise in the concept of electric current, and there are four (4) alternative conceptions on the concept of electrical resistance. These results indicate that the conception that high school students have in relation to concepts in the subject matter of a simple electric circuit still deviates from scientific conception and leads to misconception.

Abstract
The study was aimed at analysing the students- creative thinking skills at SMP Negeri 2 Bandung, focusing on the fluency, flexibility, originality, and elaboration aspects in solving the flat-side geometry problems. The descriptive type with qualitative approach was used. Tests, interviews, and documentation were utilized as the data collection methods. The students of class VIII-D were chosen as the subject, six of whom were taken as the sample, consisting of two students with high mathematical skills, two moderate, and two low. The findings reveal that the students with high mathematical skills experience no obstacle in the fluency and flexibility aspects, while in the originality aspect the inability to provide creative answers is sill exhibited by some students, and in the elaboration aspect the students represent lack of accuracy and detail in answering the elaborative questions. The moderate mathematical-skilled students still indicate difficulty in understanding the problems given, whereas the low mathematical-skilled students show difficulty in understanding the problems that, therefore, they can merely provide less-structured, unsystematic, undetailed answers, and they do not solve many problems as well. This is due to considerable obstacles they still experience.

Abstract
Double Loop Problem Solving (DLPS) is one of the learning models that purpose to improve mathematical problem-solving skill. As a DLPS learning model, the constructivism approach is one of the learning approaches that can be applied to improving students mathematical problem-solving skill. The purpose of this study was to determine the effect of applying the DLPS learning model with constructive approaches to students mathematical problem-solving skill. To realize this goal, quasi-experiments was done in 3 South Tambun Senior High School. Two classes were selected using the Cluster Random Sampling method. The DLPS learning model with the constructivism approach is applied to the first class, while conventional learning models are applied to others. Students mathematical problem-solving skill are measured through tests made based on indicators of problem-solving skill. Before starting the program, the initial skill of students is calculated based on the results of the PAS (Final Evaluation). The program was carried out eight meetings, during which the eighth meeting was conducted post-test. The hypothesis was tested using an independent sample t-test with a significant probability of 0.05. The results of the study show that there is a positive influence on the application of the DLPS learning model with the constructivism approach to students mathematical problem-solving skill (p-value <0.05). The results showed that the average test results of students mathematical problem-solving skill with the DLPS learning model with the constructivism approach were higher than those of students with conventional learning models. This research is in line with the research conducted by (1) Jatisunda M. Gilar (2017) the constructivism approach has a positive influence on students mathematical problem-solving skill. (2) Pratama (2018) DLPS learning model has a positive influence on students mathematical problem-solving skill. This manuscript is based on the research that we have done.

Abstract
One of the abilities of the 21st century that students must have is creativity, but this ability is not too meaningful if it is not accompanied by a good spiritual attitude (in accordance with the 2013 curriculum in Indonesia), as well as always being a concern for public schools research is rarely focused on religious-based schools (madrasah) even though the potential is no less great than public schools. So from that the aim of this study is to analyze the creativity and spiritual attitudes of students who appear in STEM-based reproductive system learning through performance assessment. The research methodology is descriptive, sample used was one of 11th grade classes in “Science” specialization in MAN 2 Tasikmalaya with 36 students as participants. Creativity here is seen from a creative person (Person), the creative process (Process), the pressure that arises (Press), and the product it produces (Product). The results of the research show that the students of madrasah (in this case MAN 2 Tasikmalaya) have different levels of creativity, both compared in terms of "person", "process", "press", and "product" no one has a level of creativity same. On average students have "emerging" category creativity. Creativity is also not directly related to students personal spiritual attitudes, however, some students who have very good spiritual attitudes tend to have creativity that is categorized as "expressing".

Abstract
Mathematics is a compulsory subject that students must learn since on elementary school, because of its usefulness on daily lives. But many obstacles experienced by students in learning mathematics, one of which is mathematical anxiety. This study aims- to explain how students mathematical anxiety is seen from gender factors and their implications. The subjects of this study were 10 grade V students of an elementary school in Sumedang. Case study methods are used to understand and analyze students mathematical anxiety. The results of the study were obtained from data collected through questionnaires, mathematics test, interviews and the field notes of mathematics learning process which was then analyzed descriptively. The research results show that mathematical anxiety of female students tended to be higher when compared to male. This mathematical anxiety will increase when students face exams. The implication is that the concentration of students with a high level of math anxiety tends to be disturbed when learning mathematical material. Although this doesn-t always have an impact on the results of student learning tests, but the conditions of learning must be arranged in such a way that students are more comfortable and mathematics anxiety can be reduced while students studying.

Abstract
In the Education curriculum, mathematics is a compulsory subject that must be learned by students since elementary school, because of its usefulness for students daily lives. But many obstacles experienced by students in learning mathematics, one of which is mathematical anxiety. So, this study aims to explain how students- mathematical anxiety is viewed from gender factors and its implications. The subjects of this study were 10 students of 5 graders, an elementary school in Sumedang. Case study method is used to understand and analyze students- mathematics anxiety. The results of the study were obtained from data collected through questionnaires, interviews and field notes when the mathematics learning process took place which was then analyzed descriptively. During the study it was observed that mathematical anxiety of female students tended to be higher when compared to male students. This mathematics anxiety will increase as students face exams. The implication of students with high levels of mathematics anxiety tends to be distracted by their concentration in learning mathematical material. This then has an impact on the acquisition of student learning outcomes that are less than optimal. Thus the lower the level of students- mathematical anxiety, the higher the mastery of students mathematical concepts.

Abstract
One of the mathematical topics that must be mastered by students is geometry. Geometry requires students to think analytically and spatially so they must have good spatial abilities. Each student has different spatial abilities in learning geometry. Several previous studies relating to spatial ability are about differences in students- spatial abilities based on gender. However, almost no research can be found on the students-s spatial abilities based on level of geometrical thinking. This condition raises research questions about description of students-s spatial abilities based on Van Hieles level of geometrical thinking. Therefore this study aims to identify students-s spatial abilities based on Van Hieles level of geometrical thinking. To answer the research question, we gave a written test to 25 grade IX students in one of junior high school in Bandung. Then, we conducted interviews to 3 upper group students and 3 lower group students. Data analysis was done by triangulation method. The results of this study indicated that there are variations in differences in each indicator of spatial ability based on the level of Van Hieles geometrical thinking. In the spatial perception, mental rotation, and spatial orientation, the maximum level achieved by students is level 2, namely 11, 5, and 3 students, respectively. Meanwhile the indicator of visualization and spatial relation, the maximum level achieved by students are level 1, namely 16 and 15 students, respectively.

Abstract
This study aims to find out how the learning process of mathematics in disabilities of unsociable and slow learners which involved teacher preparation before the learning process, implementation of learning and follow-up evaluation and what are the barriers faced by special needs students during the learning process of mathematics in inclusive class of SMA Negeri 10 Kota Ternate. This research is a qualitative descriptive study. The type of research used is a type of field research with data collection techniques through observation, interviews and documentation. The research subjects in this study were mathematics teachers in inclusive class. The data analysis technique used in this research is data collection, data reduction, data presentation, conclusions, and verification. Data validation uses the time triangulation technique. The results of the study show that several things are as follows: (1) Before mathematics learning process takes place, the subject prepared lesson plan, syllabus, media and learning resources but there was still not specific for special needs students, (2) Subject prepared students psychologically and physically, asked introductory questions and repeats basic mathematics concept. The subject made a group that combined special needs students and normal students in one group, (3) Subject took the initiative to ask directly to special needs students which parts of the material were not yet understood. Especially, basic mathematical concepts for students is done more slowly and often repeated. Special needs students get bored quickly following the mathematics learning process, therefore the teacher maked a group, so special needs students can interact with normal students.
