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…

This study assessed the effectiveness of a professional development program for junior high school mathematics teachers in the Philippines and analyzed their achievement test results in Mathematics. The study aimed to identify the factors affecting the quality of mathematics instruction and propose solutions to these challenges. The study found…

This paper sought to explore the Knowledge of Algebra for Teaching and the algebra difficulties of In-field and Out-of-field Junior High School mathematics teachers using the expanded KAT framework. The study employed the descriptive survey design and involved the participation of 374 mathematics teachers using an achievement test instrument. The…

Mathematical thinking is closely related to students' success in solving mathematical problems. Local culture can be a resource to teach mathematical thinking skills. Nonetheless, a lot of teachers still struggle to help students develop their mathematical thinking abilities. This study aims to investigate the ethnomathematics approach applied by…

This study examined students' ability to learn mathematics in a self-directed teaching environment. One of the main goals of the educational system is to nurture independent learners who can grow up to be inquisitive, critical, creative, and capable of piloting their own learning. This implies making a change in the way the role of the mathematics…

Teaching effectiveness is a core issue in educational research; however, there is little consensus about the most important results of classroom teaching from an international perspective. The effectiveness of teaching has remained a 'black box' for a long time. In the secondary study described in this paper we used empirical data for Shanghai…

The importance of literacy is a competency requirement that must be possessed by students to face competition in the 21st century. This is directly related to the extent to which students' scientific thinking processes understand and solve problems. This study aims to describe how literacy is trained in learning in junior high schools. The…

The Indonesian 2013 curriculum requires the learning process to provide opportunities for the students to develop their higher order thinking skills. Many studies believe that the use of manipulatives are effective to foster it. However, we found that the manipulatives only available for the classroom use, while the students need to also exercise…

Questioning is recognised as a well-established aspect of good mathematics teaching, and this study draws on this instructional practice to provide multilingual learners high-level mathematics, discourse, and cognitively demanding mathematics. Three seventh grade mathematics teachers engaged in professional learning to develop their questioning…

The COVID-19 pandemic switched the learning activity at school to be home learning. In Indonesia, the practice of uploading paper-based worksheets is the most practice conducted during pandemic. Many students feel disengaged with the activity, leading to a decline in their study results. The use of paper-based worksheets itself also brings…

This study sought to investigate in-service mathematics teachers' knowledge of differentiated instruction in junior high schools in Tano South Municipality of Ghana. The study adopted an explanatory sequential mixed method design. We employed a sample of 50 JHS mathematics teachers comprising 41 general in-service teachers and 9 special in-service…

Problematic learning situations (PLS) arise when students encounter learning difficulties and their teacher encounters difficulties assisting them. The current study looks at student and teacher difficulties revealed during PLS, in the course of instruction of basic geometrical concepts for average and below-average junior high school students,…

Teacher-students interaction is one of the most important interactions in learning. Teacher-students interaction affects student understanding. However, in practice, there are still many lessons that have not applied teacher-students interaction properly. This study aimed to reveal teacherstudent interaction in the mathematics learning process…

The purpose of this mixed-methods study was to investigate the relationship between teachers' conceptions of mathematics and their use of intelligent tutoring systems for mathematics instruction. Intelligent tutoring systems are adaptive computer programs which administer mathematics instruction to students based on their cognitive state. A…

This research paper aims to produce a mathematical module with a problem-solving approach to train student's reflective thinking. To find out how to develop modules, there are three criteria must be fulfilled, namely validity, practicality, and effectiveness. Development of module used four stages, namely the initial situation analysis, design…
