Although research highlights the importance of analyzing the geometric work of teachers, there are few validated instruments in this line. This study presents the processes of design and validation of a forced-choice questionnaire that allows the characterization, from a theoretical basis, of how geometry teachers organize their teaching practice.…

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…

Owing to the importance of a subject like mathematics in the teaching and learning of science, self-learning often poses a challenge to the educator. The objective of this study is to analyse the enhancement of the textual and the media form of self-learning modules to teach algebra and geometry to eighth graders considering their retention…

Since probability is a new topic at the primary school level in many countries, many primary school teachers may consider themselves not well prepared or may not value the formative role of probability as a topic for their students to learn. Consequently, the assessment of teachers' attitudes using valid and reliable instruments is a preliminary…

Many classroom-observation instruments have been developed (e.g., Gleason et al., 2017; Nava et al., 2019; Sawada et al., 2002), but a very small number of studies published in refereed journals have rigorously examined the quality of the ratings and the instrument using measurement models. For example, Gleason et al. developed a mathematics…

Teaching simulations such as scriptwriting tasks offer a novel way to support pre-service teachers in gaining diagnostic competencies and in guiding students to work through difficulties. We first report on the theory-driven development of a scriptwriting task, specifically the theoretically-founded language- and accompanying content-related…

This study aimed to develop a three-dimensional geometric thinking test to determine the geometric thinking of early graders in the paper-pencil environment. First, we determined the components of three-dimensional geometric thinking and prepared questions for each component. Then, we conducted the pilot studies of the test at three stages in six…

The aim of this research is knowing whether research instrument is feasible or no to get data of research. The instrument of this research is logical mathematics quotient test with 25 problems in multiple choice and mathematics problem solving test with 4 questions in essay. Testing the appropriateness of instrument of logical mathematics…

The present paper studies the effects of lesson study as a sample of participative researches in classroom as well as Behrangi Education Management Model in courses by aiming at exploring and allowing students to use the indexes of course concepts as an effective model in learning. The research plan is pre-test, posttest with control group type.…

In this paper, the authors report research focused directly on the validation of the Coding of Academic Teacher-Student interactions (CATS) direct observation instrument. They use classroom information gathered by the CATS instrument to better understand the potential mediating variables hypothesized to influence student achievement. Their study's…
