Journal on Mathematics Education (JME), formerly called Indonesian Mathematical Society Journal on Mathematics Education (IndoMS-JME), is the first international journal on mathematics education in Indonesia. The primary goal of the journal is to support and facilitate mathematics educators and researchers either from Indonesia or other countries to publish their works in mathematics education.Â In 2010, Professor Zulkardi, the vice president of the Indonesian Mathematical Society (IndoMS) as well as a mathematics educator from the Universitas Sriwijaya started the JME.Â Professor Widodo, the president of IndoMS at that time, launched the first volume of the JME at the opening of National Conference on Mathematics in Universitas Negeri Manado, June 30th, 2010. This editorial focuses not only on the celebration of the achievements and challenges of JME but also the process of the growth of the JME from a local journal, national, and then to be a reputable international journal.First, as a local journal, JME started with only five articles in the first volume. Luckily, an international expert in mathematics education wrote and published their ideas.Â Â Lee Peng Yee, a professor at the National Institute of Education (NIE) Singapore, wrote an article about how to design a mathematics curriculum. Also, Professor Sembiring, from the Institut Teknologi Bandung, wrote about the history of Realistic Mathematics Education in Indonesia. Later on, many authors from various countries published their papers in the next volumes. Some of the well-known researchers in mathematics education have contributed to the JME, such as Professor Berinderjeet Kaur from Singapore; Kaye Stacey, Bardini, and Tom Lowrie from Australia; Christa Kaune and Elmar Cohort from Germany; Edyta Nowinska from Poland; Koeno Gravemeijer, Maarten Dolk, Dolly and Frans van Gallen from the Netherlands. The other authors are from the Kingdom of Saudi Arabia, Brunei Darussalam, Indonesia, Turkey, Ghana, United States, and Taiwan.Â Second, the JME is nationally accredited by the Ministry of Research, Technology, and Higher Education since September 2015. A year before, the Directory Open Access Journal (DOAJ) and ERIC databases started to index the articles from the JME.Finally, after waiting for 20 months since the application submitted, the JME is accepted for the Scopus inclusion since September 2018, addressing the JME as one of the reputable international journals from Indonesia. After another three months, Elsevier agreed to cover all articles since volume 9.1 in the Scopus database.Â Â In this celebration moment, as the editor in chief, I would like to say thank you very much to all local staffs, managing editors, reviewers, as well as editorial board members either from abroad or Indonesia who have done excellent work in making JME well known and internationally recognized. Starting from January 2019, JME publishes three editions on each volume.Finally, in the future, JME has an effort to improve the quality of publication both management and the content of the articles.Â Also, JME has a task to fulfil the requirements to be indexed in the Web of Science. Of course, this is not an easy task, especially for JME team.

Publisher : Department of Doctoral Program on Mathematics Education, Sriwijaya University

This study attempts to analyze pre-service secondary mathematics teachersâ€™ flexibility of external representations of domain and range of functions. To reach the purpose, a task consisted of thirty question items were designed. Participants of the study were thirty-eight Indonesian pre-service secondary mathematics teachers attending mathematics education department at one private university in Jakarta, Indonesia. Based on the analysis participants written responses, this paper revealed participantsâ€™ difficulties in providing a proper and consistent definition of the concept of domain and range of functions. We also disclosed the participantsâ€™ lack of flexibility in doing translation among representations under the concept of domain and range of function. In general, participants written responses to the task did not provide evidence of a solid understanding of domain and range. There are several implications of these findings offered for secondary mathematics teacher educationâ€™s program.

This research is aimed to explore the cultural elements especially in Sasak architectures in Lombok Island such as a home living (Bale), worship building (masjid), lumbung (sambi) in ethnomathematics point of view. This research uses qualitative approach with cognitive (anthropology cognitive). The interviewees are the experienced custom leader and humanists who has conducted the research on Sasak society. Meanwhile, the data collection method used the participant, observation and documentation. Data analysis on this research is not only based on the researcher is interpretation but also the idea structure of the society.Â This research shows the evidence of sensitivity on the use of numbers practiced by Sasak ancestor long time ago in doing the measurement using their anthropometric ability (Ethnomathematics). The architecture products of sasak society also describe that sasak society is more focus on the process than the final products itself which describes the consistency in conducting role and cultural device which control the desire of individual construction.

This study aims to produce valid and practical PISA-like mathematics problems of uncertainty and data content by using soft tennis and volleyball contexts in Asian Games. It also aims to find out the potential effect of the problems on students' mathematical literacy. The method used in this study was design research with the type of development studies. The validity was viewed from expert assessment regarding the content, constructs, language, and studentsâ€™ comments to the clarity of the problems in the one-to-one phase. Then, the practicality was viewed in the small group phase, and it was found that the students could understand the problem well. Based on the answers from 33 tenth-grade students of senior high school, it was found that the problems had potential effects that arouse the ability to use symbolic, formal, and technical language, as well as the ability of operation, communication, and representation. With the problem of the soft tennis context, five students could apply the ability to use symbolic, formal, and technical language, and operations, 12 students could apply representation ability, and 16 students could apply the communication ability. Meanwhile, with the problem of the volleyball context, 18 students could apply the communication ability, and nine students could apply the representation ability.

STUDENTSâ€™ COGNITIVE PROCESSES IN SOLVING PROBLEM RELATED TO THE CONCEPT OF AREA CONSERVATION Ekawati, Rooselyna; Kohar, Ahmad Wachidul; Imah, Elly Matul; Amin, Siti Maghfirotun; Fiangga, Shofan

This study aimed to determineÂ the cognitive processÂ employed in problem-solving related to the concept of area conservation for seventh graders.Â Two students with different mathematical ability were chosen to be the subjectsÂ of this research. Each of them was the representative of high achievers and low achievers based on a set of area conservation test.Â Results indicate that both samples performedÂ more cyclic processesÂ on formulating solution planning, regulating solution part and detecting and correcting error during the problem-solving. However, itÂ wasÂ found that theÂ highÂ achiever student performed some processes than those of low achiever. Also, while the high achiever student did not predict any outcomes of his formulated strategies, the low achiever did not carry out the thought process after detecting errors of the initial solution gained. About the concept of area conservation, the finding also reveals that within the samplesâ€™ cognitive processes, the use of area formula come first before students decided to look for another strategyÂ such as doingÂ â€˜cut-rotate-pasteâ€™ for the curved planes, which do not have any direct formula. The possible causes of the results were discussed to derive some recommendation for future studies.
