Focus and Scope

Lemma : Letters of Mathematics Education welcomes high-quality manuscripts resulted from a research project in the scope of mathematics education, which includes, but is not limited to the following topics:

Realistic Mathematics Education

Realistic Mathematics Education (RME) is a teaching and learning theory in mathematics education that was first introduced and developed by Freudenthal. Two of his important points of view are mathematics must be connected to reality and mathematics as a human activity. RME is implemented following three principles, they are: (1) guided reinvention and progressive mathematizing, (2) didactical phenomenology, and (3) self-developed model. Furthermore, the practice of RME also has its own characteristics, they are: (1) phenomenological exploration or the use of contexts, (2) the use of models or bridging by vertical instruments, (3) the use of students own productions and constructions or students contribution, (4) the interactive character of the teaching process or interactivity, and (5) the intertwining of various learning strands. A paper is eligible to be included in this topic if the paper accommodates these three principles and these five characteristics. The researches (ideas of research) on related topics can be traced to the works of Hans Freudenthal, Marja van den Heuvel-Panhuizen, K.P.E. Gravemeijer, and published books in Springer or other publishers.

Design/Development Research in Mathematics Education

Educational design research is perceived as the systematic study of designing, developing and evaluating educational interventions (programs, teaching-learning strategies, and materials, products, systems) as solutions to such problems. It also aims at advancing our knowledge about the characteristics of these interventions and the processes to design and develop them. Authors could submit their work, either a validation study or a development study in mathematics education, with a comprehensive description and analysis of every stage. The ideas of this research on related topics can be traced to the works of Jan Van den Akker, Koeno Gravemeijer, Susan McKenney, Nienke Nieveen, Tjeerd Plomp, Arthur Bakker, and published books in Taylor & Francis or other publishers.

Mathematics Ability

Mathematics ability refers to the ability (a human construct) to obtain, to process, and to retain mathematical information (cognitive) and to solve mathematics problems (pragmatic). To maintain the focus of this journal, the scope of mathematics ability includes the following abilities: reasoning, connection, communication, representation, and problem-solving. A paper is eligible for this topic if it comprehensively discusses those abilities. The researches (ideas of research) on related topics can be traced to the works of Markku S. Hannula, CERME Proceedings, ICME Proceedings and published books in Springer or other publishers.

ICT in Mathematics Education

The advance of information and communication technology (ICT) has been the concern of all human life, including in education. When all students use technology, education must be the first one to utilize it for the sake of effectiveness and attractiveness. The researches (ideas of research) on related topics could be traced to the works of Paul Drijvers, Willem J. Pelgrum, Tjeerd Plomp, Jean-Baptiste Lagrange, Michèle Artigue, Colette Laborde, Luc Trouche, and published books in Springer or other publishers.

Ethnomathematics

Ethnomathematics is the study of the relationship between mathematics and culture. In a deeper understanding, ethnomathematics refers to mathematics which is practiced by members of a cultural group who share similar experiences and practices with the mathematics that can be in a unique form. Culture gives diverse and interesting contexts in mathematics learning to be discussed. Therefore, the scope of ethnomathematics is an important part of the focus and scope of the journal. The ideas of this research on related topics can be traced to the works of Marcia Ascher, Ubiratan d'Ambrosio, Robert Ascher, Marcelo C. Borba, and published books in Springer, Taylor & Francis, or other publishers

Artikel

Checked Open Submissions Checked Indexed Checked Peer Reviewed
 

Peer Review Process

Articles submitted to LEMMA: Letters of Mathematics Education (2407-4527) (2460-1047)  will be evaluated through 2 stages of review, ie pre-review and substance review.

The pre-review of the article is carried out by the editorial team to review the conformity of the article with the focus and scope of the journal as well as the journal style and LEMMA: Letters of Mathematics Education author guidelines. Plagiarism checking is carried out by using Google Scholar and Turnitin software.  Duration of review between 1-2 weeks.

Substantial single-blind reviews are performed by at least 2 reviewers. Duration of review between 3-8 weeks. If desired, the reviewer may request a re-review after the author revises his/her article.

The decision of whether the article can be published is authorized by the Editor in Chief by considering recommendations from reviewers. Articles that have been accepted and have been in-layout will be published in the In Progress issue before the regular issue is published on schedule, so they can be indexable and citable immediately.
