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.…

Mathematical abstraction skills are fundamental for advanced reasoning and problem-solving, yet assessing these skills in senior high school students poses challenges due to limited validated instruments. This study aims to develop and validate a test instrument for measuring mathematical abstraction skills in Indonesian high school students. The…

Assessing preservice' higher order thinking skills (HOTS) in science and mathematics is essential. Teachers' HOTS ability is closely related to their ability to create HOTS-type science and mathematics problems. Among various types of HOTS, one is Bloomian HOTS. To facilitate the preservice teacher to create problems in those subjects, an Android…

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…

The character of responsibility is an important character that Indonesian students must possess. The attempts to strengthen the character of student responsibilities require in-depth information about the actual state of student's responsibility. The use of relevant, valid, and reliable instruments is necessary to obtain accurate and accountable…

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…

The study presented in the paper has the following goals. The first is to review and compare teacher competence frameworks developed in Eastern (Chinese) and Western (German) contexts, exemplified for the domain of mathematics. Major similarities of the two contexts could be reconstructed in the conceptualization of teacher competence as a…

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.…

Introduction: The Approaches and Study Skills Inventory for Students (ASSIST Short Version) was used to better understand the students' approaches to learning in a mathematics classes. Method: Quantitave method was used in this study. Participants were 345 first and second year mathematics students from a university in the Gauteng province of…

The purpose of this study was to develop a Mathematics test instrument testlet model for a classroom assessment at elementary school. Testlet Model is a group of multiple choice question acquiring similar information with different grade of responses model. This research was conducted in East Lombok, Indonesia. The design used was research…

The purpose of this study is developing a valid and reliable scale intended to determine the irrational beliefs of students in mathematics. The study was conducted with a study group consisting of 700 students in 2015-2016 academic year. Expert opinions were received for the content and face validity of the scale, and the Exploratory Factor…

Test score validity takes center stage in the debate over the use of high school exit exams. Scant literature addresses the amount of conditional standard error of measurement (CSEM) present in individual student results on high school exit exams. The purpose of this study is to fill a void in the literature and add a national review of the CSEM,…
