Personalized System of Instruction (PSI) and Lesson Study (LS): a comparative analysis of two successful teaching methods

Abstract

Educational researchers are concerned with the investigation and improvement of teaching methods, and data obtained this study evidences their efficacy. The Personalized System of Instruction (PSI) and Lesson Study (LS) are two evidence-based effective teaching methods applied in varied disciplines in several countries with different theoretical backgrounds, procedures and evaluation strategies. In general, PSI research focuses on student development, lesson planning relies on an instructor, instructions are written, evaluation based on experimental manipulation, and shortcomings involve issues like student procrastination, excessive preparation and supervisor training time. LS research focuses on teacher and student development, instructions are varied, the assessment is based on a performance of the student, and teacher perception and shortcomings include excessive meeting time. This article suggests that both PSI and LS can benefit from the investigating implementation of each other's features. Keywords: Teaching and Learning, Personalized System of Instruction, Lesson Study, Comparative Analysis. RESUMO:Os pesquisadores educacionais estão preocupados com a investigação e aperfeiçoamento dos métodos de ensino e os dados obtidos evidenciam a sua eficácia. O Personalized System of Instruction (PSI) e Lesson Study (LS) são dois métodos de ensino efetivos baseados em evidências aplicados em disciplinas variadas em países com diferentes contextos teóricos, procedimentos e estratégias de avaliação. Em geral, a pesquisa do PSI concentra-se no desenvolvimento do aluno, o planejamento de lições depende de um instrutor, as instruções são escritas, a avaliação baseia-se em manipulação experimental e as deficiências envolvem problemas como a procrastinação dos alunos, a preparação excessiva e o tempo de treinamento do supervisor. A pesquisa do LS concentra-se no desenvolvimento do professor e do aluno, as instruções são variadas, a avaliação é baseada no desempenho do aluno e na percepção do professor e as deficiências incluem o excessivo tempo de reunião. Este artigo sugere que tanto PSI quanto LS, podem se beneficiar com a implementação investigativa dos recursos uns dos outros.

“…In the subsequent processing of hand image segmentation, in order to avoid the interference of non-target areas on feature point extraction, non-target areas need to be pruned. In this paper, processing techniques such as image filtering, image binarization and image morphological processing were used to process the images before and after segmentation of the hand image [15].…”
