The present study aimed to develop a valid and reliable instrument to determine the symbolic mathematics language literacy perceptions of junior high school students, and to investigate literacy perceptions based on gender, final mathematics achievement scores, significance of using symbols, and school grade variables. The study group included 312…

Disciplinary literacy strategies in mathematics lessons are essential and may be embedded in three necessary parts of the lesson: before reading, during reading, and after reading. In this article, we highlight disciplinary literacy strategies that middle school mathematics teachers might implement to guide students to increased mathematical…

One area of education which has not escaped efforts to improve the Indonesian government is mathematics education. The Indonesian government must make good use of mathematics learning so that students can use the mathematical mindset to offset the pace of global competition. This research is an experimental research on the Process-Oriented Guided…

In this study, the purpose was to make use of metaphors to determine the difficulties experienced by secondary school 6th and 7th grade students in the process of learning the subject of circle. In the study, the phenomenological research design, one of qualitative research methods, was used. The research data were collected from a total of 140…

Improving the strength of alignment between educational components is essential for quality assurance and to achieve learning goals. The purpose of the study was to investigate the strength of alignment between Senior Phase mathematics content standards and workbook activities on numeric and geometric patterns. The study contributes to…

Critical to constructing and interpreting graphs is an individual's understanding of the underlying coordinate systems, yet coordinate systems are often overlooked or taken-for-granted in both mathematics education research and curricula. In this paper, we foreground coordinate systems and present a distinction between two uses of coordinate…

This study aimed to develop the blended learning design using the Kelase platform with learning concepts that internalize the Tri Kaya Parisudha concept and the Mathematics material structure by using Superitem concept so that the Mathematics learning process at the level of high school or vocational can be more effective. This research was…

There are opinions about approaching the proof in mathematics education need to change as providing students to understand the mathematical proof rather than developing formal mathematical proof skills. In this context, proofs without words described as informal proofs can be used in proof teaching. The purpose of this study was to investigate the…

Following a line of inquiry regarding the exact number of real roots of a real polynomial, this investigation considers: Descartes' Rule of Signs, the Budan-Fourier Theorem, and versions of Sturm's Method in contrast with the approximate root count gleaned from graphing utilities. Online applets are provided to allow the reader to freely…

Purpose: Since there are a limited number of studies on how to develop relational thinking in secondary school students in mathematics education literature, this study will contribute to the field both in theoretical terms and concerning the implications for in-class applications. In this respect, this study aims to examine how to develop the…

This study explored the teaching and learning beliefs of qualified (in-field) secondary science teachers who were teaching mathematics out-of-field that is, without qualification. The relationship between secondary teachers' beliefs about their in-field subject--science and their out-of-field subject--mathematics was examined. The theory of…

This paper reports the results of the experimentation of a didactic engineering for the treatment of the sense of variation of functions with pre-university students. The theoretical references of the investigation are grounded in the theory of didactic situations and the methodological elements in the didactic engineering, the use of…

While various studies suggest that informal statistical inference (ISI) can be developed by young students, more research is needed to translate this claim into a well-founded learning trajectory (LT). As a contribution, this paper presents the results of a cycle of design research that focuses on the design, implementation, and evaluation of the…

Although teachers are expected to teach with technology, they often are not prepared or supported to do so (Albion, Tondeur, Forkosh-Baruch, & Peeraer, 2015), a critical issue in mathematics education (Wilson, 2008). The study described in this article investigated why and how secondary mathematics teachers implemented virtual manipulative…

Previous research has shown that adults from migrant backgrounds often have lower numeracy competence than do their majority counterparts, even though many were educated in their host country. Leaving secondary education with lower levels of numeracy competence than majority students potentially makes migrant students vulnerable as adults, as the…
