3D geometry is an essential concept in mathematics because it relates to real-world experiences and numerous mathematical topics. However, some students still have difficulty understanding this geometry. Therefore, this study aims to identify and describe students' epistemological obstacles to the dimensions of representation, spatial structure,…

In this study, it is aimed to reveal what kind of relationship exists between prospective teachers' thinking structures and their level of writing proofs. This study was carried out as a case study. The study was carried out with 82 prospective teachers enrolled in the Department of Secondary School Mathematics Teaching of a state university…

Euclidean geometry provides an opportunity for learners to learn argumentation and develop inductive and deductive reasoning. Despite the significance of Euclidean geometry for developing these skills, learner performance in mathematics, particularly geometry, remains a concern in many countries. Thus, the current study examined the nature of…

Classroom teachers' awareness of the characteristics of students with mathematics learning difficulties is important for the planning and implementation of individualized intervention programs for students. This study aims to examine classroom teachers' awareness of students with mathematics learning difficulties, as well as the mathematics…

Students' difficulties in algebra are generally caused by the use of algebraic notation, the meaning of letters, as well as the types of relationships or methods used. Therefore, interpreting letters in algebra is one of the critical points in the transition from arithmetic to algebra. However, many students have misconceptions in interpreting…

Teachers' knowledge, beliefs, and attitudes contribute to the success of classroom instruction. Teaching approaches that are informed by teachers' good content knowledge of mathematics they teach are regarded as more effective and produce high learning outcomes. It is critical that teachers possess both content and pedagogical content knowledge as…

Students' higher-order thinking skills (HOTS) in Indonesia are still low and have not experienced significant development. To enhance HOTS, modern technology-based learning media are needed to support realistic mathematics learning. Innovative learning media can enhance realistic learning and students' thinking abilities. Therefore, the authors…

This correlational study addressed two issues pertinent to developing mathematical competences for the 21st Century. Firstly, in a post-digital society, technology is recognized in teachers' pedagogic and subject-specific knowledge domains. Secondly, cross-curricular teaching must be introduced to respond to societal requirements for maths…

Information and Communication Technology (ICT) implementation in education is a national priority in Bhutan, particularly as it relates to the STEM disciplines. Researchers at Samtse College of Education introduced 19 experienced secondary school mathematics and physics teachers to The Geometers' Sketchpad and GeoGebra in two workshops. At the end…

Open Educational Resources (OER) was first introduced in universities as a cost-saving option to traditional textbooks. In 2015, the U.S. Department of Education announced the #GoOpen initiative, challenging school districts nationwide to convert at least one course from traditional curriculum resources to OER. Existing research has focused on the…

For years, the vast majority of California's community college students had to take remedial courses that slowed down or halted their academic progress. In 2019, Assembly Bill (AB) 705 removed many of these barriers, making it much easier for students to access and complete gateway transfer-level courses in English and math--a key early milestone…

For years, educators have been using "foldables" as a visual and/or kinesthetic approach to note taking within elementary school classrooms. The purpose of the study is to determine to what extent these foldables have on students' self-efficacy of grade level math concepts. We previously found that there were learning gaps in students'…

Encouraging students' ability to reason can be looked at through the lens of both oral and written representations. In 2022, the author participated in the first intake of the Teacher Excellence Program run by the Victorian Teaching Academy. Being part of an in-depth professional learning program challenged the author's teaching practices to focus…

In this study, I examined the ways in which teachers' facilitation techniques are associated with students' mathematical thinking. The teachers' beliefs and students' perception about mathematics discussions were also examined in order to determine whether or not the connection of the teachers' facilitation techniques with students' thinking were…

Seaford School District has allocated significant resources and launched multiple initiatives to increase the achievement of Seaford Middle School mathematics students. These included adopting high quality instructional materials, hiring a school-based mathematics coach, purchasing curriculum materials, ensuring collaborative grade level planning…
