“…Fraser et al (2011), in a study focusing on enhancing lesson planning and quality of classroom life for mathematics students' use of technology, addressed that technology enhanced students' quality of life by facilitating their lesson planning, helping them stay on track, reducing their stress, and making it easy for them to adjust, modify, and reuse their lessons. Sharil and Kyriacou (2015) conducted an explorative study regarding the impact of reflective practice in developing pre-service teachers' professional development, particularly on instructional planning, by focusing on what entails reflective practice and instructional planning, the dimensions that underpin reflection, and how the convergence between reflection and instructional planning may contribute to pre-service teachers' professional development. To investigate how prospective secondary mathematics teachers design lesson plans using their pedagogical content knowledge, Emre-Akdogan and Yazgan-Sag (2018) study points out three main findings, namely prospective teachers preferred to use student-centred and technology-based teaching activities, they took the students' understandings and prior knowledge into consideration, and they experienced difficulties since their mathematical content knowledge is not in comply with the conceptions included in the curriculum.…”
