Improving the use of physical manipulatives in teaching science concepts through lesson study

Abstract

Purpose – The purpose of this paper is to present how lesson study can be instrumental in improving the use of physical manipulatives that are used in teaching elementary science topics. Design/methodology/approach – Objectives are achieved through the following means: first, planning a research lesson in the workshop; second, presentation and critiquing in a seminar workshop; third, implementing the research lesson with observation of co-teachers and knowledgeable other; fourth, post lesson discussion; and fifth, revising the research lesson. Findings – The research lesson improved significantly after the first post lesson discussion as the concrete to abstract approach was used and the defect of the physical manipulative (eardrum model) was addressed to avoid possible misconceptions from pupils during discussions as part of the formative assessment portion of the lesson. Research limitations/implications – The lesson study process was not further extended to the third and fourth implementation to see other problems in the use of their physical manipulative (eardrum) model. Practical implications – The need for teachers to use the physical manipulative as an analogical model in teaching science concepts. Originality/value – The paper shows the effectiveness of lesson study in the development of manipulative models in instruction.

Integrated Macro-Micro-Symbolic Approach in Teaching Secondary Chemistry

“…The effective nature of IMMSA in teaching Chemistry concepts was in consonance with Bruner's Three-tiered model of learning which stated that learning should be taught from concrete to abstract levels, leading to a balance in the curriculum. Noted in this sequence of learning activities is the essential use of laboratory experiments which provided insights to the exploration of the five postulates of KMT of gases, thereby leading the students to develop science process skills such as observation and inference skills (Tan, 2015). This could be due to the fact that the macroscopic activities included reflect everyday phenomena that students observe and do.…”

A systematic review of transparency in Lesson Study research: how do we report on the observation and reflection stages?

“…Although it is generally acknowledged that LS includes the core stages of studying, planning, teaching and observing, and reflecting, these stages are flexible and can be tailored to various cultural contexts, professional climates, and the specific needs of individual schools or systems . This has led to various conceptualizations of LS that follow specific procedures, such as Collaborative Lesson Research in the United States (Takahashi and McDougal, 2016) or Lesson Study for a Learning Community in Japan (Saito et al, 2015). Other examples of adaptations relate to the focus of classroom observations (Dudley, 2013), the refinement and reteaching of a lesson (Quaresma and Da Ponte, 2021), or the use of specific protocols to structure teachers' observations and their reflection process (e.g., Faerøyvik Karlsen, 2019;Kager et al, 2022).…”

Using a non-coercive process to engage mathematics teachers in lesson study

“…In the Philippines, lesson study has been slowly gaining attention as a professional development model for teachers because of its claimed benefits to teaching and learning (Gutierez, 2015;Tan, 2015). But for lesson study to be successful, collaboration with other teachers is very important (Ermeling and Graff-Ermeling, 2014).…”
