Abstract:
The purpose of this study was to analyze the differences in learning outcomes between students who received snow cube throwing and students who received an expository learning model. In addition to these objectives, another objective of this study is to test the effectiveness of using the snow cube throwing learning model on student learning outcomes. The research method used was a quasi-experimental with a non equivalent control group design. The population of this study were all students of class XI at SMAN 5 Cimahi. The sample in this study consisted of 2 groups, namely the experimental class and the control class selected by purposive sampling. Each group consisted of 40 students, so that there were 80 students who were sampled in this study. Data analysis in this study used the independent sample t-test and effect size. The results of the data analysis show that the learning outcomes of students who get the snow cube throwing model are better than the learning outcomes of students who get the expository model. The effectiveness of using the snow cube throwing model is more effective in improving student learning outcomes, as indicated by the value of the effect size which is included in the high category.

Abstract:
Several facts about learning mathematics in high school, show that students' mathematical thinking skills are still low. Therefore, there needs to be an effort to increase these variables, considering that these variables are very important in supporting students' academic achievement. This study discusses the application of a comprehensive mathematics instruction (CMI) model in mathematics learning as an effort to improve students' mathematical thinking. This research is a quasi-experimental research. The sample was taken purposively from the population of high school students in Subang Regency, West Java, Indonesia. The instruments used in the research consisted of a mathematical thinking ability test and an observation sheet. Mathematical thinking ability is built by four important aspects, namely specializing, generalizing, conjecturing and convincing. The CMI model is a learning model that accommodates three stages, namely develop, solidify and practice. Each of these stages provides the opportunity for students to develop specializing, generalizing, conjecturing and convincing aspects. The results showed that the CMI model can improve students' mathematical thinking abilities. Thus, the CMI model deserves to be used as an innovation in mathematics learning.

Abstract:
This study aims to describe procedural fluency in solving problems for students of the Mathematics Education Department at the STKIP Pamane Talino who obtain high and low mathematical dispositions through learning assisted by Google Classroom. This research is a qualitative research. The research subjects were two students in the third semester. Subjects were selected by purposive sampling. The research data was obtained by tests and interviews, and the validity of the data was obtained by using the triangulation method. The techniques of data analysis were trough: 1) classifying data into three indicators of the smoothness of the procedure; namely: a) implementing procedures appropriately, b) selecting and utilizing procedures, c) modifying procedures, then reducing data that are not included in the 3 indicators; 2) presenting data in a narrative; 3) concluding the procedural fluency obtained from the indicators of procedural fluency in problem-solving steps. The results of the high mathematical disposition analysis showed that students had excellent procedural skills because they could apply procedures appropriately. They were able to select and utilize procedures accurately, and were able to apply procedures properly and flexibly. In the other side, the students with low mathematical disposition, they had poor procedural skills because even though they were able to apply the procedure, choose, and use the procedure appropriately, they still could not comply with the procedure appropriately and accurately for they answered all the questions incorrectly.

Abstract:
The development of the education curriculum in Indonesia makes students must have skills so that they can compete globally, especially in the 21st century. The development is closely related to technology and information. One of skills that support the development of technology and information is the computational thinking skills. This study aims to analyze students’ computational thinking skills on the number patterns lesson during the Covid-19 pandemic. This study was qualitative-descriptive research with the subjects of 4 students from 8th grade in Makassar. The instruments used in this study were a test of the computational thinking skills in the form of essay type test on the number patterns lesson and interview guidance. The results of this study indicated that all subjects met the first indicator of problem decomposition and one subject met the second indicator of problem decomposition, all subjects met the indicator of pattern recognition, three subjects met the indicator of abstraction and generalization, all subjects met the first indicator of algorithmic thinking and two subjects met the second indicator of algorithmic thinking on computational thinking skills. Thus, students’ computational thinking skills during the Covid-19 pandemic were still low, so an educational framework is needed to improve students’ computational thinking skills.

Abstract:
This study aims to validate multiple representational instruments to analyze the ability of multiple representations of students on hydrocarbon material. This research uses a descriptive quantitative method with a non-experimental approach. This research uses the stratified purposive sampling method with 123 students who will respond to 35 items of multiple-choice questions covering macroscopic, microscopic, symbolic, and mathematical aspects. The data analysis technique used in the research is qualitative data analysis and quantitative data analysis. The Rasch model in this research analyzed instruments such as unidimensionality, item fit, test reliability, and difficulty level of the item. The data analysis shows that the average Aiken index is 0.961 on the substance aspect, 0.93 on the construction aspect, and 0.950 on the language aspect for the theoretical validation results. The highest Aiken index is 1.000, and the lowest is 0.896. Unidimensionality was 32.4%, the result of the item fit analysis obtained 1 item that was not fit, namely item number 29, and for the reliability test results: the person reliability value was 0.65, and the item reliability was 0.97. The analysis results of the difficulty level of the items on the instrument of measuring the cognitive abilities of students with multiple representations types were nine items in the easy category, 14 items in the medium category, and 11 items in the difficult category. Therefore, based on the resulting validity and reliability categories, the compiled test instrument can be used as a tool to measure students’ multiple representation abilities.

Abstract:
The aim of this study is to create an image of how research integrates in university teaching particularly in STEM education in a state university in the Philippines. The participants were 104 teachers from five campuses of the university that offers STEM undergraduate programs. A quantitative research design was employed to address the central theme: The identification of the gap between the beliefs and perceptions of STEM Educators regarding the role of research in university teaching. The present study revealed that the STEM teachers highly valued the role of research in teaching. They especially considered the development of creative and critical dispositions as the most important goals of integrating research into teaching. However, the teachers reported low actual integration of research into their current teaching, revealing a major gap between their beliefs and the perceived actual integration research into their own teaching practices. It further showed that institutional background appeared to be critical in the integration of research in teaching. Ultimately, STEM education in the university is emphatic on research content in the delivery of instruction while creating opportunities for learners to participate along the learning process. However, a research-based approach remains to be unpopular, much less for a research-oriented classroom. Strengthening research support and widening the scope of research culture are recommended.

Abstract:
During the Covid-19 Pandemic, the learning process used by teachers is in the form of digital media. This research is focused on digital learning, barriers faced by teachers, and various approaches to overcome various obstacles faced by teachers in implementing digital learning during the covid 19 pandemic. The type of research is qualitative research with a survey method. This research was conducted in Sumenep Regency with primary school teachers as the research object. The data collection consists of questionnaires given to 100 teachers and interviews to 9 teachers to describe information related to the focus of the research. The results of this study show that teachers do not directly utilize various digital platforms of various learning technologies implemented in online learning during covid 19. The obstacles experienced by the teachers include the teacher's low ability in applying the information technology, parents' economic factor, unstable internet networks, and the absence of information technology training given by schools. On the other hand, as time goes by teachers are able to implement the digital learning independently and adapt to the surrounding environment and understand the various characteristics of students in making use of digital in learning during the COVID-19 pandemic.
