Suprapto, Edy; Saryanto; Sumiharsono, Rudy; Ramadhan, Syahrul – Journal of Turkish Science Education, 2020
This research aims to produce feasible and valid assessment instrument of Higher Order Thinking Skill (HOTS) to measure students' Higher Order Thinking Skill in Physics learning. The type of this research was research and development, adapted from development model from Brog and Gall. The researchers modified Borg and Gall's development model as…

Mabotja, Samuel; Chuene, Kabelo; Maoto, Satsope; Kibirige, Israel – Pythagoras, 2018
This article uses parts of qualitative data from the first author's study that focused on exploring Pirie and Kieren's process of "folding back," revisiting previously held understandings of a concept for its extended understanding in order to solve the problem of enhancing Grade 10 learners' reasoning in geometry. In South Africa,…

Walkington, Candace; Wang, Min; Nathan, Mitchell J. – Grantee Submission, 2019
Collaborative gestures in the mathematics classroom occur when multiple learners coordinate their bodies in concert to accomplish mathematical goals. Collaborative gestures show how cognition becomes distributed across a system of dynamic agents, allowing for members of groups of students to act and gesture as one. We explore ways high school…

Bokosmaty, Sahar; Sweller, John; Kalyuga, Slava – American Educational Research Journal, 2015
Research has demonstrated that instruction that relies heavily on studying worked examples is more effective for less experienced learners compared to instruction emphasizing problem solving. However, the guidance associated with studying some worked examples may reduce the performance of more experienced learners. This study investigated…

Papadopoulos, Ioannis; Iatridou, Maria – Journal of Mathematical Behavior, 2010
In this paper two 10th graders having an accumulated experience on problem-solving ancillary to the concept of area confronted the task to find Pick's formula for a lattice polygon's area. The formula was omitted from the theorem in order for the students to read the theorem as a problem to be solved. Their working is examined and emphasis is…

Stylianides, Andreas J. – Mathematics Teaching, 2009
A proof's potential to promote understanding and conviction is one of the main reasons for which proof is so important for students' learning of mathematics. Unless students realise the limitations of empirical arguments as methods for validating mathematical generalisations, they are unlikely to appreciate the importance of proof in mathematics.…

Cerulli, Michele; Mariotti, Maria Alessandra – International Group for the Psychology of Mathematics Education, 2003
In the framework of a long term teaching experiment we present an Educational approach based on the use of a dynamic geometry software and a symbolic manipulator. Here we present the general ideas of the followed approach focusing on how meanings can originate from phenomenological experience and evolve under the guidance of the teacher. In…
