The Standards for Mathematical Practice (SMPs; CCSSI, 2010) describe mathematical behaviors and habits that students should express during mathematics instruction. Teacher candidates should have knowledge about the SMPs and their implications for mathematical instruction. This study aims to share the validity evidence for interpretations of…

Growth mindset in mathematics is an approach to teaching mathematics, believing that students' abilities can be developed with efforts, strategies, and support. With a sample of 178 middle school students, this study proposed a scale for mathematical mindset utilizing Boaler's positive norms in teaching mathematics and collected evidence for…

The purpose of this development research is to create a self-efficacy instrument to assist students learning mathematics that is valid, practical, and reliable. A self-efficacy questionnaire is the format of the instrument that was created. The main driving force behind this research is the scarcity of empirically validated self-efficacy surveys…

Across the world, standards and practices for preparing teachers of mathematics emphasize the importance of math modeling (MM) in developing students' mathematical thinking. The aim of this research study was to develop the Mathematical Modeling Knowledge Scale (MAMKS), capable of determining preservice teachers' (PSTs') knowledge of MM. The study…

Mathematical thinking beliefs are a significant element in supporting teachers' practices of learning and teaching school mathematics. Most prior researches on mathematics beliefs have focused on teachers' beliefs about learning and teaching mathematics in general. This research aimed to validate a Mathematical Thinking Belief instruments (MTB).…

While proof has been studied from different perspectives in the mathematics education literature for decades, students continue to struggle to build proof comprehension. Complicating this, the manner in which proof comprehension is assessed largely remains to be the definition-theorem-proof format in which students are asked to reproduce proofs or…

Mathematical language (or the content-specific words in mathematics) has repeatedly shown to be related to mathematical abilities in preschool and in the early grades of primary education. Research in this field has predominantly focused on young children's quantitative and spatial language. At the same time, recent research has discovered that…

Mathematics education is looking for innovative methods to foster problem-solving skills in students. This research develops a problem-solving assessment using GeoGebra Classroom, a versatile interactive mathematics software, to revolutionize mathematics formative assessment and improve students' problem-solving skills. This study adopted the…

Background: The STEM education system has garnered significant interest due to its innovative approach in creating a multidisciplinary and integrated knowledge structure that connects science, technology, engineering, and mathematics, and allows students to apply scientific knowledge in a comprehensive and holistic manner. Consequently, evaluating…

Mathematics education needs measures that can be used to research and/or evaluate the impact of professional development for constructs that are broadly relevant to the field. To address this need we developed the Priorities for Mathematics Instruction (PMI) survey consisting of two scales focused on the constructs of Explicit Attention to…

This study, in which the explanatory mixed design was used, has two aims. The first aim is the development of a scale to determine teachers' beliefs about the integration of mathematics and children's literature. The second one is to examine the beliefs of teachers on children's literature and mathematics teaching, with the data collected through…

This study aimed to develop a specific Mathematical Content Knowledge (MCK) test focused on multiplication for pre-service mathematics teachers in Indonesia and Türkiye. No assessment tool exists to measure MCK related to multiplication among pre-service mathematics teachers. We used convenience sampling to obtain data from third- and fourth-year…

A multiple regression analysis was conducted to investigate what variables may predict the student's self-perceived proficiency in mathematics. Hence, this quantitative cross-sectional survey design aimed to explore the factors predicting the student's self-perceived proficiency in mathematics using gamified instruction. Two hundred twenty-five…

The quality of teachers' mathematical knowledge for teaching (MKT) is critical for effective teaching and mathematical learning of students. However, most efforts on measuring MKT tend to focus on teachers' content knowledge (CK), with less attention to teachers' pedagogical content knowledge for teaching (PCK). This study reports on our initial…

Teacher education quality and effectiveness have been at the centre of policy discussions in the last decades. As part of efforts to improve teacher preparation, law 20.903 requires Chilean universities to design and apply diagnostic tests assessing the construct of their choice to all first-year preservice teachers. Based on these results,…
