The study was performed with quantitative research method by using a quasi-experimental design, namely, the pretest-posttest control group design. The research was conducted with the participation of six primary schoolteachers and 167 third-year students who were enrolled at six different sections in two different primary schools at the center of Ağrı province of Turkey. The participants were selected through purposive sampling method. As the data collection tool, the academic achievement test which was prepared by the researchers was utilized. The practice of the lesson study took seven weeks and was performed in the context of achievements referred to in the Life Sciences Course Instruction Program in relation to ‘Life at Our Home’ unit. At the primary school with relatively low socio-economic and academic achievement levels, there was an increase in the academic achievements of the experimental groups in association with the practice of lesson study whereas there was no statistically significant difference in the control group. At the primary school with relatively high academic achievement and socio-economic levels, there was a statistically significant increase in the academic achievements of both the experimental groups and control group. Upon the analysis of research findings, it was found that there was a significant improvement in students’ academic achievements in association with the practice of lesson study practice particularly at schools with low level of academic achievements.  \nKeywords: Lesson Study, Professional Development, Primary School Teacher, Life Sciences Course  \nDOI: 10.29329/epasr.2020.334.14  \n1PhD student, Institute of Social Sciences, Department of Primary Education, Amasya University, Amasya, Turkey, ORCID: [0000-0003-0693-0359](0000-0003-0693-0359 Correspondence: mucahitayra@hotmail.com)[ Correspondence](0000-0003-0693-0359 Correspondence: mucahitayra@hotmail.com)[: mucahitayra@hotmail.com](0000-0003-0693-0359 Correspondence: mucahitayra@hotmail.com)  \n2Doç .

Lalitha (2005) defines the teacher education as activities organized for developing teachers’knowledge base, skills and understanding for the purpose of enhancing their thinking and classroom behaviors. Guskey (2000) perceives it as a continuous and systematic process which is consciously designed and aspires to enhance the individual’s professional knowledge, skills and attitude with a view to improving students’ learning outcomes. During professional development activities performed at schools individually and in groups, teachers transform the school into a learning setting collectively in a cooperative environment through efforts to reach certain results, exchange information, find common solutions to problems, overcome communication challenges, solve school problems and so on (Kösterelioğlu & Akın Kösterelioğlu, 2008) . Lieberman (2000) stated that the professional development was an integral part of the daily school life and there should be continuity in professional organizations. A good quality professional development process will enhance the quality of teacher’s practical activities and subsequently will have positive effect on the learning process of students (Borko, 2004) .  \nIn this conjunction, professional development models were p","cbCaigihUrkXHGvx","https://ap.wps.com/l/cbCaigihUrkXHGvx","pdf",409944,22,"English","# Introduction\n## Professional development and teacher education\n## Lesson study concept and background\n# Abstract\n## Research aim and design\n## Participants and procedure\n## Findings\n# Keywords","[{\"question\":\"What is the purpose of the study?\",\"answer\":\"To examine the effect of lesson study practice on primary school students' academic achievements in a Life Sciences course.\"},{\"question\":\"How was the research conducted?\",\"answer\":\"It used a quantitative quasi-experimental design with a pretest-posttest control group format, involving purposive sampling.\"},{\"question\":\"What were the key results of the lesson study practice?\",\"answer\":\"Academic achievements increased for experimental groups at lower socio-economic and achievement schools, with no statistically significant difference in the control group.
