Thesis (M. Ed. (Science Education)) -- University of Limpopo, 2019 / The purpose of the study was to investigate the effect of Jigsaw Method on Grade 12 learner’s performance in reaction rates in Maleboho Central circuit as one of the improvement strategies. A quasi-experimental design with the Experimental Group (EG) and the Control Group (CG) was utilised to determine the effect of the Jigsaw Method on learners’ performance as compared to the chalk-and-talk approach. The population of the study was made up of 315 Physical Science learners from ten schools that offer Physical Science in Maleboho Central Circuit. Two poorest performing schools from the same circuit were selected purposively from the population. One class at School A and another at School B were selected randomly as EG and CG, respectively. The sample consisted of 21 learners from school A (EG) and 23 learners from school B (CG). An achievement test with 21 open-ended questions was used as a pre-test as well as a post-test. Data from the tests were analysed using descriptive statistics. In the experimental group, the findings indicated that there was a significant difference between pre-test scores and posttest scores with p=.022. According to the results from Cohen’s d (-0.94), the gain was large in EG as evidenced by the effect size (-0.95). The results of the t-test (t= 9.54, p=0.00) indicated that there was a statistical significance between the posttests of EG and CG. Data analysed through ANCOVA (p=0.00) revealed that the Jigsaw Method was more effective than the traditional chalk-and-talk approach. Employing the Jigsaw Method in the Science classroom can help teachers to promote learners’ participation and hence to improve their academic performance.

In this context, we understand that nowadays the teaching and learning of chemistry reveals as a big challenge, by demanding a process which the studentâs everyday should be anchored in, claiming for a significant approach that increases the seizure of the contents and stimulation of critical thinking among the current knowledges on the didactic mediation. The main question of the research was based on the use of investigative-cooperative teaching methodologies, therefore, the developed methodology was done by direct survey and the research target were (25) students on the last year of high school (in Brazilian patterns, third degree) on the Public School Raimundo Viana Pinto, located on the state of ParÃ. The research has concluded that when the method is questioned in a cooperative learning context, the stimulation of investigation culture and interactively contact is increased. Besides that, the didactic strategy applied had a great interest with the students, improving study groups, autonomy development, awaking among them values of social integration and responsibility, special condition to form a critical citizen within his/her life in society.

In this paper we use Astronomy as background and motivating element so that we approach concepts of optics, waves and contemporary Physics, using the cooperative learning Jigsaw methodology. Astronomy insertion is a potential learning motivator and through it we aim to construct a potentially significant didactic material. Therefore, we developed activities that use the concept of color and spectroscopy, which were presented concomitantly with traditional topics present in the curriculum. With the Jigsaw method, we have established collaborative groups for practical and theoretical activities. We emphasize that all of them have been idealized so as not to require the use of computers. The final products include a didactic sequence and materials for its application: 15 thematic cards for the Jigsaw application and two activities, one on spectra calibration and another on the Doppler effect in galaxies, where it is possible to observe the shift to red of lines in galaxies spectra obtained from astronomical databases. About the calibration activity, we provided all steps for the obtaining and treatment of the home spectra (including tutorial videos) and how to obtain standard values data spectral lines by a technical rules institute of the United States, aiming at replicability. During the lessons we promote the comparison between spectra coming from different light sources in order for us to discuss with the students stars light nature. This proposal’s three classes occurred in a public school in Aracaju city, Sergipe. Through students answers in the pre-test and in the post-test, both made without statistical purposes, as feedback to our practice, it was possible o notice improvement indications in correct answers quantity made possible by the activities described here, which suggests that the Jigsaw method is possible, if we do not get slightly better results through meaningful learning, at least the same learning occurs with a great gain to the interaction process among all the participants. These tests provided data regarding our practice, making it possible the discussion about methodological corrections. We could realize that the Jigsaw method, through its proposed social interaction, has demonstrated to be potential facilitator of significant learning and to aggregate learning process involved individuals. / Neste trabalho usamos a Astronomia como pano de fundo e elemento motivador para abordamos conceitos de óptica, ondulatória e Física contemporânea, usando a metodologia de aprendizagem cooperativa Jigsaw. A inserção da Astronomia é um potencial motivador da aprendizagem e através dela objetivamos construir um material didático potencialmente significativo. Para tanto, desenvolvemos atividades que se utilizam do conceito de cor e da espectroscopia, que foram apresentados concomitantemente com tópicos presentes na grade curricular tradicional do Ensino Médio. Com o método Jigsaw, estabelecemos grupos colaborativos para as atividades práticas e teóricas. Destacamos que todas as atividades foram idealizadas de forma a não necessitar do uso de computadores. Os produtos finais incluem uma sequência didática e materiais para sua aplicação: 15 cartões temáticos para a aplicação do Jigsaw e duas atividades, uma sobre a calibração de espetros eletromagnéticos e outra sobre o Efeito Doppler em galáxias, onde é possível observar o desvio para o vermelho de linhas em espectros de galáxias obtidos de bancos de dados astronômicos. Sobre a atividade de calibração, disponibilizamos todos os passos para a obtenção e tratamento dos espectros caseiros (incluindo vídeos tutoriais) e sobre como obter dados de valores padrões das raias espectrais disponibilizados por um instituto de normas técnicas dos Estados Unidos, visando sua replicabilidade. Durante as aulas promovemos a comparação entre espectros provenientes de diferentes fontes luminosas de modo a discutir com os alunos a natureza da luz advindas dos astros. As três aulas dessa proposta ocorreram em uma escola pública na cidade de Aracaju, Sergipe. Através das respostas dos estudantes no pré-teste e no pós-teste, feitos sem fins estatísticos, apenas como um feedback de nossa prática, foi possível notar indícios de melhora na quantidade de acertos possibilitadas pelas atividades aqui descritas, o que sugere que com o método Jigsaw é possível, se não obtivermos resultados ligeiramente melhores com a aprendizagem significativa, pelo menos obtem-se a mesma aprendizagem com um grande ganho para o processo de interação entre todos os participantes. Estes testes forneceram dados a respeito de nossa prática, possibilitando a discussão sobre correções metodológicas. Pudemos perceber que o método Jigsaw, através da interação social que propõe, demonstrou potencial facilitador da aprendizagem significativa e agregador entre os indivíduos envolvidos no processo de aprendizagem. / São Cristóvão, SE

The need to prepare and motivate the student is part of a challenge to all involved in this process. The use of cooperative learning with its numerous techniques, contribute to the development of fundamental aspects of a future engineer as the understanding of the role of each individual in a work group, the development of the sense of responsibility and organization, the coexistence with different opinions, the constant learning from co-workers and the need to express themselves clearly. Studies show that understanding the thinking styles of the students can help teachers to offer a better quality instruction to maximize learning outcomes. Researches with elementary school students on styles of mathematical thinking, which are classified into visual, analytical and integrated thinking, show that understanding these styles can help the students to learn mathematics. Within this scenario, the main objective of this research is to identify and analyze ways in which cooperative learning strategy promotes the mobilization of different styles of mathematical thinking by engineering students. To this end we created an activity using the jigsaw method of cooperative learning, developed by Elliot Aronson, involving the study of lines in two and three-dimensional spaces and tested with students in the first year of Engineering School. The results show that this method could make changes in styles of mathematical thinking of some students. It was observed that only students who were initially classified belonging to the integrated or visual had changed their styles, moving to the analytical. It was noticed that the prevalence is the analytical mathematical thinking style, which in part may be a result of the influence exerted by the teacher on students, as this style is valued in the traditional model of education / As dificuldades enfrentadas pelos ingressantes nos cursos de Engenharia estão geralmente vinculadas às disciplinas da área de Matemática. A necessidade de preparar e motivar o aluno faz parte de um desafio colocado a todos os envolvidos neste processo. A utilização da aprendizagem cooperativa, com suas inúmeras técnicas, contribui para o desenvolvimento de aspectos fundamentais na formação do engenheiro, tais como: a compreensão do papel de cada indivíduo na realização de um trabalho em grupo, o desenvolvimento do senso de responsabilidade e organização, a convivência com opiniões distintas, o aprender constante com colegas de trabalho e a necessidade de se expressar claramente. Estudos mostram que compreender os estilos de pensamento dos alunos, pode auxiliar os professores a estabelecerem mudanças em sua prática de ensino no sentido de maximizar os resultados da aprendizagem. Pesquisas sobre estilos de pensamento matemático, que são classificados em visual, analítico e integrado, com alunos do ensino básico, mostram que conhecer tais estilos dos estudantes pode ajudar na aprendizagem da Matemática. Diante deste cenário, o objetivo principal dessa pesquisa é identificar e analisar em quais aspectos a estratégia de aprendizagem cooperativa propicia a mobilização dos diferentes estilos de pensamento matemático por estudantes de Engenharia. Para tanto criou-se uma atividade, utilizando o método jigsaw de aprendizagem cooperativa, desenvolvido por Elliot Aronson, envolvendo o estudo de retas nos espaços bi e tridimensionais, que foi trabalhada junto com os alunos ingressantes de um curso de Engenharia. Os resultados apontam que a utilização de tal método influenciou na mudança de estilos de pensamento matemático de alguns alunos. Observou-se que apenas estudantes que foram inicialmente classificados como pertencentes ao integrado ou visual tiveram seus estilos alterados, passando para o analítico. Percebeu-se que a predominância é do estilo de pensamento matemático analítico o que, em parte, pode ser consequência da influência exercida pelo professor sobre os alunos, uma vez que tal estilo é valorizado no modelo tradicional de ensino

This study was motivated by the lack of in-service training in cooperative learning and science process skills whereas both are emphasized in the new natural sciences curriculum. The aims of the study were to determine the influence of cooperative learning on the development of science process skills. Two classes were selected from two rural schools for inclusion as case studies of this research. These classes were taught using the Jigsaw and Group Investigation methods of cooperative learning respectively. Pre- and post-tests were administered on the two classes and the influence of these methods on learners' achievement on four process skills were determined. Mixed results were found with regard to the influence of the two cooperative learning methods on the development of learners' process skills of observation, controlling variables, graphing and experimenting. / Educational Studies / M.
