<![CDATA[The Numbered Heads Together (NHT) model of learning enables students to grasp the purpose behind the teacher’s instruction in order for the students to become motivated to learn from the teacher. The subjects in this study were students from class A, a total of 28 students. Each of the conducted studies involved planning, implementation, observation and reflection stages. Data collection was performed using both observation and tests. According to the results of the initial test (pre-test)-before the action-the grade average was 56.4 with the level of students’ learning outcomes as many as 7 students (25%) still scoring very low, but the action-incorporating the Numbered Heads Together (NHT) learning model by the teacher in the first cycle-led to some improvement. Improved learning outcomes obtained following the first cycle, with the class average score being 62.3, indicating that the level of mastery under standard instruction amounted to as many as 13 students (46.4%) still classified as moderate, whereas students’ activities or actions based on observations made by peers were relatively low at 60.5%. As the aforementioned increase did not reach the set standard values, efforts needed to be made to improve and develop during the second cycle. Following the second cycle, the post-test revealed further improvement in the average grade value, which increased to 70.4, and the level of students’ learning outcomes under standard instruction with as many as 19 students (67.9%) belonging to the good category; the standard instruction underwent changes in learning and students’ actions or activities were classified as good, reaching as high as 80.3. ]]>

<![CDATA[Understanding the concepts of applied chemistry in the Graphic Engineering Study Program at the Creative Media State Polytechnic is very important to support their field of expertise in understanding more complex material. The Applied Chemistry course consists of various abstract concepts, including acids and bases. The use of computer programs such as PhET media is very important to explain the abstract material. The aim of this study was to describe the use of PhET Simulation, knowing the effectiveness of using PhET Simulation media in acid-base practicum, knowing the advantages and disadvantages of using PhET Simulation in acid-base practicum, and the purpose of this study was to see student learning outcomes after the application of PhET media in learning. The method used is a descriptive method that begins with the manufacture of media devices and student worksheets and performs a descriptive analysis of learning outcomes after the application of learning. The trial subjects in this study were first semester students who programmed the Applied Chemistry course. The research instrument is a learning outcomes test which finds 10 numbers of true and false questions and 5 numbers of essay questions. The results showed that the application of PhET media was effective in acid and base practicum. The average student learning outcomes are 65 ± SD 18 (good category). Based on student assessments after learning, it was found that students were very happy to learn by using PhET media.]]>

<![CDATA[This study aims to determine the relationship between gender and students’ thinking skills and compare their score between male and female based on their level of thinking skills. Moreover, the result of this study can also be used to evaluate the implementation of the 2013 Curriculum on mathematics junior high school especially Higher-Order Thinking Skills. The method used in this study is ex-post facto, with a population of all 7th grade public junior high schools students in Banjarmasin city. Sample taken were 391 students, divided into 6 schools that were selected randomly. The instrument used is 16 multiple choice test that is valid and reliable. This developed test respectively focused on measuring thinking skills, namely Remembering, Understanding, Applying, Analyzing, Evaluating, and Creating. The result showed that female students were better than male students in almost all of the thinking skills, except Creating. However, there is no relationship between gender and thinking skills.]]>

<![CDATA[The educational implementation is a learning process at all levels, students are required to follow certain lectures, including mathematics courses. Learning difficulties are a barrier to learning where children are not well educated, due to disturbances, both from student factors and external factors. learning, thus students are expected to catch up because of these obstacles. This research is classified into qualitative descriptive research that seeks to describe the analysis of student learning difficulties in statistical subjects. The subjects in this study were the fourth-semester students of 2018/2019 Mulawarman University. Research reveals things that are considered as a barrier factor for students in Statistics. In this study, the researcher collected information through documentation, tests, and interviews with students. The results of the analysis show that the difficulties of students in studying Statistics basically lie in the weakness of the concept. The results of the research conducted by the researcher were the existence of errors in process skills, errors in understanding questions, and errors in using notation. The solution to overcoming these problems is: for the eye teacher of Statistics to be able to develop learning strategies so that students can be more honed in their thinking skills and provide continuous problem training to students.]]>

<![CDATA[Experiences at the educational personnel education institution, Department of Mathematics Education Institute of Teacher Training and Education Pontianak (IKIP) shows that students often had difficulty in proving propositions (theorems in mathe-matics). The alternative offered through this study was to develop students' abilities in proof through mathematical communication. The study method used in this study was qualitive research, case study. The subjects used in this study consisted of two un-dergraduate students who had been taught real analysis introductions and. The data collection tool used was tests and interview. Data analysis techniques used was de-scriptions: data reduction, data display and conclusion. Based on the results of re-search, study of theory and discussion, it could be concluded in this study that the student obstacles in answering mathematical proof questions are the students have difficulty in writing mathematical symbolic and inability in mathematical proof. But after being given didactic anticipation by mathematical communication, the ability of students to answer mathematical proof questions has increased. Thus, mathematical communication can be used as an alternative to overcome obstacles or difficulties for students in solving mathematical proof problems.]]>

<![CDATA[Culture is closely related to the lives of Indonesian people, in the current era of technological sophistication, culture is one of the means to study science, one of which is ethnomathematics. Ethnomathematics is a branch of mathematics that uses culture as a means to deepen the knowledge and concepts of mathematics education through the role of culture in society. This study focuses on the ethnomathematical exploration of the “ompangan” tradition of the Jember Madura community in Kalisat with the aim of describing ethnomathematics in the ompangan tradition of the community and formulating the concept of mathematical calculations. This research took place at Jalan Diponegoro Dusun Krajan 1 RT/RW 012/004 Glagahwero Kalisat. This study uses a qualitative method with a descriptive approach, with data collection techniques through interviews and observations. The results showed that the ompangan culture contained mathematical concepts in it that linked culture to the mathematical counting process, namely the concept of worth comparison and a system of linear equations used to determine the number of goods with the same price or value.]]>
