Classroom discipline, classroom environment and student performance in Chile

This paper assesses the extent to which teachers’ actions in the classroom influence the school environment. The assessment is based on a statistical analysis of videotaped classroom observations of 51,329 teachers. The classroom environment was found to have a significant influence on students’ performance. More specifically, the teacher’s ability to handle the class as a group is consistently more significant than other measures of class environment. It was also founds that the overall school environment is a better predictor of students’ test results than the environment in the classrooms of the students whose test results are being reported. This suggests that the most effective course of action would be to improve the overall school environment, although individual teachers have less control over this factor.

Análise de metodologia baseada no sistema de ensino individualizado de Keller aplicada em um curso introdutório de eletromagnetismo

Uma das metodologias de ensino individualizado mais usadas e documentadas na década de 70 foi o Sistema Personalizado de Instrução (SPI) de Fred Keller. Diversas pesquisas sobre essa metodologia foram publicadas, as quais proveram extensa evidência empírica de seus resultados positivos. Apesar disso, a aplicação desse sistema de ensino entrou em declínio a partir da década de 80. Dentre as razões para tal declínio, podemos destacar o maior esforço requerido para a elaboração de cursos utilizando essa metodologia e para o provimento de feedback sistemático ao desempenho dos alunos, assim como o surgimento de críticas a ela devido à abordagem comportamentalista de Keller. Mesmo sendo fundamentais para a aprendizagem, o estímulo à postura ativa do estudante, o respeito ao ritmo individual de aprendizagem, as avaliações formativas e o provimento de feedback sistemático ao aluno continuam frequentemente fora das salas de aula. Uma estratégia para suprir tais carências é o ensino individualizado. Neste trabalho, propomos várias modificações ao SPI de Keller visando uma metodologia viável de ser empregada em um curso introdutório de eletromagnetismo para estudantes de física da Universidade Federal do Pará. Dentre estas modificações, destacamos: (i) o emprego de avaliações semanais, e não em todas as aulas; (ii) a correção das avaliações e provisão de feedback feitas pelo professor, e não pelos monitores; e (iii) a manutenção parcial de aulas expositivas. Com base em uma avaliação incluindo parâmetros mensuráveis, obtivemos indícios de que, apesar das modificações introduzidas, a aplicação dessa metodologia permitiu obter vários dos resultados positivos comuns na aplicação do SPI de Keller.

Emergência de comportamentos autônomos na aprendizagem da língua estrangeira a partir da interface da consciência linguageira e da motivação

Esta pesquisa situa-se entre os estudos da Consciência Linguageira e a formação de comportamentos autônomos com influência do fator motivacional em aprendentes do Inglês como língua estrangeira. Considerando a relevância da explicitude dos insumos complexos e da Consciência Linguageira na instrução, observei que, ao utilizar esses princípios, o docente pode favorecer em seus aprendentes a formação de comportamentos que os levem a um maior controle de sua própria aprendizagem. Desta forma, o presente estudo tem como objetivos verificar a correlação entre Consciência Linguageira, autonomização e motivação como aspecto subliminar. O embasamento teórico deste estudo respalda-se essencialmente nas contribuições de Little (1997), Flavell (1976), Donmall (1991), Hawkings (2001), James; Garret (1991), Benson (2001), Rutherford (1987) e Van Lier (1991). Concomitantemente à investigação bibliográfica foi desenvolvida uma pesquisa - ação a fim de compreender o processo de apropriação do insumo pelo aprendente adulto, formulando hipóteses e valorizando o contexto dinâmico da sala de aula para intervir na melhoria da aprendizagem. A observação e a coleta de dados ocorreram em uma turma do 6º nível de língua inglesa, dos Cursos Livres de Línguas Estrangeiras, da Universidade Federal do Pará. Os dados procedentes das entrevistas, questionários, observações e atividades de foco na forma demonstraram que diante de situações em que o insumo linguístico apresentava maior complexidade, as produções orais e escritas ficavam comprometidas e havia menor participação dos aprendentes nas atividades de conversação. Observei ainda, que as atividades de Foco na Forma, a explicitude e as reflexões conduzidas por meio de metalinguagem aproximaram os alunos da solução de dificuldades ante os insumos complexos, e os motivaram a buscar, autonomamente, diferentes alternativas de aprendizagem. Os dados foram cruzados para as análises a respeito das implicações da Consciência Linguageira no desenvolvimento de comportamentos autônomos e da motivação sobre o desempenho dos aprendentes, permitindo uma reflexão relativa ao tema e aos insights significativos para a solução de problemas oriundos da imprevisibilidade do contexto em sala de aula.

Competences in the classroom in the perspectives of foreign language teachers

In this article we raise some considerations about teachers’ competences, from the perspective of teachers in the Brazilian public sector. The theoretical framework includes articles by Paulo Freire (2001), Philippe Perrenoud (2012), Edgar Morin (2003) and Maurice Tardif (2002) and, based on these authors, we reflect upon issues concerning teachers’ competences taking answers provided by the Brazilian language teachers as a departing point. In a teachers’ course, followed by the same teachers, we posed the main question in our study: Which competences are necessary for a teacher to be considered a good professional at present? From the answers given individually and group discussions we proceeded to a comparative analysis with the adopted framework, and other issues concerning teachers’ competences were considered as well. All the participants mentioned the same two competences, the use of technology and sound knowledge of the course content, and other competences were pointed out by the various teachers as well. Such procedure, besides providing data for our study, also helped as a self-reflexive activity for the teachers involved, about their own professional performance. Given the issues raised in the theoretical texts and the answers provided by the teachers, we expect to revisit the competences necessary for foreign language teacher efficient performance.

Using Descriptive Feedback In a Sixth Grade Mathematics Classroom

In this action research of my 6th grade math class, I investigated whether or not my students would improve their ability to reflect on their learning process when they received descriptive feedback from a peer. I discovered the process of giving and receiving feedback was challenging for the students to initially learn, but eventually using the feedback was highly beneficial. Descriptive feedback allowed the students to learn and understand their mistakes immediately, which in turn improved their learning. In my action research, I also began to discover more ways to implement descriptive feedback in my instruction so it could be more effectively for the students and efficiently so there would be less time taken out from instruction. As a result of this research, I plan to continue having students provide and receive descriptive feedback and to find more evidence of how descriptive feedback could influence student achievement.

Using Math Vocabulary Building to Increase Problem Solving Abilities in a 5th Grade Classroom

In this action research study of my 5th grade mathematics class, I investigated how students’ understanding of math vocabulary impacts their understanding of the curriculum. I discovered math vocabulary plays an important role in a student’s ability to understand daily lessons, complete homework, discuss ideas in groups, take tests and be successful on achievement tests. A student’s ability to understand the words around him (or her) in math class seem very related to his or her ability to solve word problems. Word problems are what our national assessments are all about. I also discovered that direct instruction and support of math vocabulary increased test scores and confidence in students as test takers. As a result of this research, I plan to continue to find ways to emphasize the vocabulary used in our current math curriculum. This process will start at the beginning of the year. I will continue to look for strategies that promote math vocabulary retention in my students. And finally, I will share my findings with my colleagues, so my research can be used as part of our School Improvement Goals.

Written Communication in a Sixth-Grade Mathematics Classroom

In this action research study of my sixth grade mathematics classroom, I investigated what happened to students’ mathematical achievement when they had increased practice on written explanations to problems. I wanted to see if writing out solutions to problems helped them overall in daily mathematics. By using specific mathematic vocabulary more frequently and deliberately during my instruction, I wanted to investigate whether students would correctly use specific math vocabulary in their written explanations. I also increased my expectations of the students’ written explanations throughout the research project. I wanted to determine whether students would try to meet or even exceed my expectations. I discovered that students used vocabulary more frequently in their written explanations by providing definitions of vocabulary versus using the vocabulary in context. I found little to no evidence suggesting that my students’ mathematical achievement changed through more practice on written communication; however, I did find as my expectations for the quality of students’ written explanations increased, most of my students improved their written explanations of problems and my teaching became more deliberate and specific. As a result of this research, I plan to continue having students communicate their mathematical ideas through written communication while continuing to focus on specific mathematical vocabulary and its purpose in written communication.

Exploring the Influence of Vocabulary Instruction on Students’ Understanding of Mathematical Concepts

In this action research study of my classroom of 8th grade mathematics, I investigated the influence of vocabulary instruction on students’ understanding of the mathematics concepts. I discovered that knowing the meaning of the vocabulary did play a major role in the students’ understanding of the daily lessons and the ability to take tests. Understanding the vocabulary and the concepts allowed the students to be successful on their daily assignments, chapter tests, and standardized achievement tests. I also discovered that using different vocabulary teaching strategies enhanced equity in my classroom among diverse learners. The knowledge of the math vocabulary increased my students’ confidence levels, which in turn increased their daily and test scores. As a result of this research, I plan to find ways to incorporate the vocabulary teaching strategies I have used into current math curriculum. I will start this process at the beginning of the next school year, and will continue looking for new strategies that will promote math vocabulary retention.

Writing In Math Class? Written Communication in the Mathematics Classroom

In this action research study of my seventh grade mathematics classroom, I investigated what written communication within the mathematics classroom would look like. I increased vocabulary instruction of specific mathematical terms for my students to use in their writing. I also looked at what I would have to do differently in my teaching in order for my students to be successful in their writing. Although my students said that using writing to explain mathematics helped them to better understand the math, my research revealed that student writing did not necessarily translate to improved scores. After direct instruction and practice on math vocabulary, my students did use the vocabulary words more often in their writing; however, my students used the words more like they would in spelling sentences rather than to show what it meant and how it can be applied within their written explanation in math. In my teaching, I discovered I tried many different strategies to help my students be successful. I was very deliberate in my language and usage of vocabulary words and also in my explanations of various math concepts. As a result of this research, I plan to continue having my students use writing to communicate within the mathematics classroom. I will keep using some of the strategies I found successful. I also will be very deliberate in using vocabulary words and stress the use of vocabulary words with my students in the future.

Generating Interest in Mathematics Using Discussion in the Middle School Classroom

In this action research study of my classroom of 8th grade algebra, I investigated students’ discussion of mathematics and how it relates to interest in the subject. Discussion is a powerful tool in the classroom. By relying too heavily on drill and practice, a teacher may lose any individual student insight into the learning process. However, in order for the discussion to be effective, students must be provided with structure and purpose. It is unrealistic to expect middle school age students to provide their own structure and purpose; a packet was constructed that would allow the students to both show their thoughts and work as a small group toward a common goal. The students showed more interest in the subject in question as they related to the algebra topics being studied. The students appreciated the packets as a way to facilitate discussion rather than as a vehicle for practicing concepts. Students still had a need for practice problems as part of their homework. As a result of this research, it is clear that discussion packets are very useful as a part of daily instruction. While there are modifications that must be made to the original packets to more clearly express the expectations in question, discussion packets will continue to be an effective tool in the classroom.
