Preservice Elementary Teachers&#039 / Science Knowledge, Attitude Toward Science Teaching And Their Efficacy Beliefs Regarding Science Teaching

Sarikaya, Hilal 01 September 2004 (has links) (PDF)
This study intended to explore preservice elementary teachers&rsquo / science knowledge level, attitude toward science teaching and their efficacy beliefs regarding science teaching. In addition, the contribution of science knowledge level and attitudes toward science teaching on Turkish preservice elementary teachers&rsquo / efficacy beliefs was investigated. The present study was conducted at the end of the spring semester of 2003- 2004 academic year with a total number of 750 (n=531 females / n=216 males / and n=3 gender not provided) fourth-year preservice elementary teachers who enrolled at elementary teacher education programs of nine different universities in Turkey. Data were collected utilizing three questionnaires: the Science Teaching Efficacy Belief Instrument (STEBI-B) developed by Riggs and Enochs (1990), Science Achievement Test, and Science Teaching Attitude Scale developed by Thompson and Shrigley (1986). Data of the present study were analyzed utilizing descriptive and inferential statistics. Analysis of the self-efficacy survey indicated that preservice elementary teachers had moderate sense of self-efficacy beliefs regarding science teaching on both Personal Science Teaching Efficacy and Outcome Expectancy dimensions of the STEBI-B. Also, preservice elementary teachers indicated low level of science knowledge and generally positive attitude toward science teaching. Furthermore, science knowledge level and attitude towards science teaching made a statistically significant contribution to the variation in preservice elementary teachers&rsquo / personal science teaching efficacy beliefs and outcome expectancy.

Aprendizagem de física, trabalho colaborativo e crenças de autoeficácia : um estudo de caso com o método team-based learning em uma disciplina introdutória de eletromagnetismo

Oliveira, Tobias Espinosa de January 2016 (has links)
O ensino de Física Geral nas universidades brasileiras é frequentemente relacionado a dois problemas correlacionados: dificuldade de aprendizagem e desmotivação. Ambos são agravados pela adoção estrita do método de ensino tradicional, com aulas essencialmente expositivas e praticamente sem o incentivo para a interação e colaboração entre os alunos para a aprendizagem dos conteúdos. O objetivo geral desta pesquisa é investigar a melhora na aprendizagem de Física e o desenvolvimento de crenças de autoeficácia em aprender física e em trabalhar colaborativamente por meio de uma adaptação do método de ensino ativo Team-Based Learning (TBL). Essas crenças estão diretamente ligadas à motivação, pois tratam-se de julgamentos que o sujeito tem sobre as próprias capacidades de organizar e executar cursos de ações específicos, os quais afetam seu desempenho, quantidade de esforço e persistência para alcançar seus objetivos. O TBL tem como foco melhorar a aprendizagem e desenvolver habilidades de trabalho colaborativo, por meio de uma estrutura que envolve: o gerenciamento de equipes de aprendizagem, tarefas de preparação e aplicação de conceitos, feedback constante e avaliação entre os colegas. Procuramos responder às seguintes questões: (i) Em relação ao desempenho dos alunos em testes padronizados sobre conceitos básicos de eletromagnetismo, quais os principais resultados alcançados com a implementação do TBL em uma disciplina de Física Geral (Eletromagnetismo) em um curso de Física numa universidade pública brasileira (UFRGS)? (ii) Quais as atitudes dos alunos em relação à mudança de método de ensino tradicional para o TBL? (iii) Como o TBL influencia os estudantes em relação às suas crenças de autoeficácia em aprender física e em trabalhar colaborativamente? Para responder a tais questões, adotamos as orientações metodológicas para estudo de caso de Yin e, a fim de responder a terceira questão de pesquisa, utilizamos a Teoria Social Cognitiva, em específico, o conceito de autoeficácia, de Bandura. Para a investigação, realizamos um estudo exploratório que teve duas unidades de análise, uma ampla (a turma, com 27 alunos concluintes) e outra específica, João, um sujeito cujo senso de autoeficácia inicial era baixo e que possuía um histórico de reprovações no curso de licenciatura em Física. Os resultados mostraram que os ganhos normalizados médios da turma nos três testes padronizados que foram aplicados foram semelhantes àqueles atingidos por outros métodos ativos de ensino e superiores a resultados obtidos nos mesmos testes em turmas com o método de ensino tradicional. João obteve resultados similares à média da turma em dois dos três testes. As atitudes dos alunos frente ao método de ensino foram positivas tendo sido destacadas principalmente, as tarefas de estudo prévio e as discussões em equipe. Como fatores negativos foram mencionados: o fato da disciplina ser muito trabalhosa e de não ter tempo suficiente em aula para a realização das atividades previstas. Sobre as crenças de autoeficácia em aprender física e em trabalhar colaborativamente, constatamos que as crenças dos alunos foram influenciadas positivamente pelas atividades desenvolvidas com o método de ensino, por meio das principais fontes destacadas por Bandura: experiências positivas e vicárias, persuasão social e redução de estresse. Concluímos que o TBL tem potencial para auxiliar na aprendizagem conceitual de Física e em desenvolver crenças de autoeficácia em aprender física e em trabalhar colaborativamente. Novas pesquisas são necessárias para dar continuidade a este estudo exploratório, investigando mais profundamente a aprendizagem, por meio de um referencial teórico específico, e relacioná-la com a mudança nas percepções de eficácia pessoal proporcionadas pelo TBL. / The introductory physics education in the Brazilian universities is frequently related to two correlated problems: students’ difficulties of learning and lack of motivation. In both cases, the strict adoption of traditional teaching method (lecturing), with a timid or non-existent incentive for interaction and collaboration among students, plays a major role. The main goal of this research is to investigate the improvement in the physics learning, the development of self-efficacy beliefs in learn physics and in work collaboratively through an adaptation of the active teaching method Team-Based Learning (TBL). These beliefs are directly linked to motivation, because they are based on judgments made by the individuals about their own capabilities to organize and execute specific courses, which affect their performance, amount of effort and persistence to achieve their goals. The TBL focuses on improving learning and develop collaborative work skills, through a structure which involves: management of learning teams, reading assignments and tests of concepts application, constant feedback and evaluation by peers. We tried to answer the following questions: (i) In relation to student performance on standardized tests about basic concepts of electromagnetism, what are the main results achieved with the implementation of the TBL in an introductory physics class (electromagnetism) in one physics course in a Brazilian public university (UFRGS)? (ii) What are the attitudes of the students regarding the change of the traditional teaching method for TBL? (iii) How TBL affects the students regarding their self-efficacy beliefs in learning physics and in work collaboratively? Therefore, to answer the questions, we have adopted the methodological guidelines for case study of Yin and in order to answer the third research question, we use the Social Cognitive Theory, in particular, the concept of self-efficacy, of Bandura. For the investigation, we conducted an exploratory study which had two units of analysis, a wide (the class, with 27 college students) and other specific, João, an individual whose sense of initial self-efficacy was short and had a history of failures in the course degree in physics. The results showed that the mean normalized gains of the three class standardized tests that were applied were similar to those achieved by other active teaching methods and superior to results obtained in the same tests in classes with the traditional teaching method. João achieved the class average in two of the three tests. The attitudes of the students about the method were positive having been highlighted mainly the reading assignments and team discussions. As negative factors were mentioned: the amount of work and not having enough time in class to carry out all the planned activities. About the self-efficacy beliefs in learn physics and in work collaboratively, we found that the beliefs of the students were positively influenced by the activities developed with the teaching method, through the main sources highlighted by Bandura: positive experiences, vicarious experiences, social persuasion and stress reduction. We conclude that TBL has the potential to assist in the conceptual learning of physics and developing self-efficacy beliefs in learn physics and in work collaboratively. Further research is necessary to continue this exploratory study, by investigating deeper into learning through a specific a theoretical reference and relate it to the change in perceptions of personal efficacy provided by the TBL.

Creencias colectivas en la escuela pública / Creencias colectivas en la escuela pública

Córdova, Elizabeth Rosales 10 April 2018 (has links)
This article presents the qualitative analysis of public teachers’ interviews who worked at low socioeconomic schools. We found that school contexts condition teachers’ beliefs about students’ performance and achievement. Through the emphasis on students’ difficulties, teachers reduce their responsibility for student learning. However, institutional activities oriented to teachers’ change may be related to strengthen collective efficacy beliefs which diminish their beliefs about negative conditions of low socioeconomic contexts, and motivate teachers’ pedagogical change. / En este artículo se presenta el análisis cualitativo de entrevistas a docentes de cuatro escuelas públicas ubicadas en sectores desfavorecidos. Se encontró que el contexto socioeconómico de las escuelas influye en las creencias de los docentes. Los docentes enfatizan las dificultades y los problemas de los estudiantes y explican cómo su condición social y económica está directamente relacionada a dichas dificultades. De esa forma, reducen su responsabilidad frente al aprendizaje de los alumnos. Sin embargo, al parecer, algunas prácticas institucionales orientadas al cambio docente podrían estar jugando un rol importante en el fortalecimiento de creencias colectivas de eficacia que contrarrestan sus creencias sobre las condiciones negativas de los contextos en los que trabajan e impulsan procesos de cambio en sus prácticas pedagógicas.

An Exploration of Turkish Kindergarten Early Career Stage Teachers’ Technology Beliefs and Practices

Ozel, Ozge 05 July 2019 (has links)
The purpose of this study was to explore Turkish kindergarten early career stage teachers’ self-efficacy beliefs towards technology and their technology integration practices in their classrooms by answering: What are self-efficacy beliefs of Turkish kindergarten early career stage teachers towards technology? How do Turkish kindergarten early career teachers integrate technology into their classrooms’ instructions? The study was designed as a qualitative multiple case study and guided by Bandura’s (1986) social cognitive theory and Mishra and Koehler’s (2006) TPACK conceptual framework. I conducted this study in Istanbul, where is the most crowded and metropolitan city in Turkey. The schools were chosen by the Ministry of National Education (MoNE) after the permissions were received from IRB and MoNE, and the participants were assigned by the directors of schools based on research criteria. Participants were chosen purposefully, and there were four female kindergarten teachers in their early career stages, which were identified based on Steffy, Wolfe, Pasch and Enz (2000)’ stages: novice teacher and apprentice teacher, teaching five-year-old students at technologically well-equipped classrooms, and who had a bachelor’s degree in preschool teaching. Data was collected from three sessions of semi-structured interviews and two sessions of observation based on TIM-O. Data was coded and analyzed based on Technological Pedagogical Content Knowledge (TPACK) to make sense teachers’ technology self-efficacy beliefs towards technology and Technology Integration Matrix (TIM)’s to understand their technology practice into classroom instructions.

General Education Teachers Implementing Common Core with Students in Special Education: A Mixed Methods Study of Teachers' Self-Efficacy Beliefs

Cash, Jon Leland 13 December 2014 (has links)
This embedded mixed method study addresses the problems teachers have reported in believing themselves capable to implement the Common Core State Standards with students in special education. This study examines the effect professional development on implementing the Common Core State Standards had on the participating teachers’ self-efficacy beliefs. The participants (N=21) in this study were drawn from a 20-day professional development for teachers based on implementing the Common Core State Standards. The instrument used in the study was the Teacher Efficacy Beliefs System-Self. Data were subject to both statistical and qualitative analysis. The results of this study provide insight into the self-efficacy beliefs of the participants during and shortly after professional development about implementing the Common Core State Standards with students in special education. The Wilcoxon test of signed ranks revealed a significant increase in the TEB-S subscale areas of Accommodating Individual Differences and Managing Learning Routines, but not in Positive Classroom Climate. Qualitative analysis of data found both support for the statistical findings and also contradicted the statistical findings. Further qualitative analysis showed that practices presented in the professional development such as using the arts, formative assessment, and technology were effective in maintaining their teachers’ self-efficacy beliefs after professional development. Factors unrelated to the professional development, such as support from administrators and colleagues and poorly working technology were not supportive in carrying over the increase in teachers’ self-efficacy beliefs in implementing the Common Core State Standards with students in special education. The study is framed by Social Cognitive Theory and organized into 5 parts. Chapter I provides an overview of the study. Chapter II includes a review of literature related to teachers’ self-efficacy belief’s Common Core State Standards, and professional development. Chapter III describes the methodology of the study. Chapter IV presents the results of the analysis of data. Chapter IV reports the findings of the study and presents the conclusions of the study and ideas for future research.

Self-efficacy Beliefs Of Florida School Principals Regarding Federal And State Accountability Measures

McCullers, John 01 January 2009 (has links)
This study examined how self-efficacy beliefs, a central construct of social cognitive theory, might be used to inform educational leadership and policy decisions related to school accountability measures. A survey of 112 principals in Florida was used to investigate the degree to which principals believed the goals of federal and state school accountability measures (the No Child Left Behind Act of 2001 and the Florida School Grades Plan) were actually attainable, and to what degree they believed their leadership actually helped achieve these goals. A large majority (83.8%) of respondents believed the state goals to be attainable, whereas only a minority (20.7%) believed the federal goals could be attained. This disparity was associated with a significant difference in self-efficacy beliefs related to the plans, and in the associated leadership behavior of principals. This significant difference in principal self-efficacy beliefs could predict a disparity in leadership effort toward goal attainment. The study suggested that policymakers should be cautious about revising the goals of the Florida School Grades Plan, since principals' self-efficacy beliefs related to the plan were already quite high. In contrast, the findings suggested that policymakers should look to revising the goals of the No Child Left Behind Act of 2001 to correct the dearth of principal belief in the actual attainability of its goals.

EFFICACY-RELATED BELIEFS AND PRACTICES ABOUT EQUITABLE SCIENCE TEACHING: A CASE STUDY IN AN URBAN ELEMENTARY SCHOOL

Barnes-Johnson, Joy M. January 2011 (has links)
Science "for all" programs have been advanced as the model for introducing and maintaining high standards for science education in every classroom. While standards documents have been an important equalizing force in education for the last twenty years, disparities still exist across multiple student indicators in urban schools. Teaching quality is one of the important factors that contribute to such outcomes and these disparities raise the issue of equitable teaching practices, especially in science. A review of the literature at the intersection of science education and urban education supported the creation of a construct for equitable science teaching that goes beyond content-narrowed "for all" pedagogies to more inclusive "by all" teaching approaches. Scholarship on science teaching in urban settings frequently references reform and efficacy beliefs to bound research questions. The task-specific nature of efficacy beliefs as a construct makes it particularly useful for scrutinizing teaching practices. This dissertation used case study methods to examine aspects of equitable science teaching in an elementary school located in a small urban district in New Jersey. The research design was based on models of collaborative action research. Three key informants in two classrooms helped build understanding of teachers' efficacy-related beliefs about equitable science teaching over the course of one year (Spring 2008 through Spring 2009). Within case and between-case analysis of teaching beliefs and practices were conducted. Key findings from the study suggest that it may be possible to observe change in low efficacy teachers' beliefs over time. Quantitative and qualitative data suggest that it may be possible to build equitable beliefs and practices among in-service teachers. An action plan that includes providing non-evaluative support to teachers in the classroom is discussed. Supports that included immediate feedback, individual and small group reflection and specific tools designed to collect teacher-level data were shown to be important elements for practicing teachers as they worked to build both efficacy beliefs and equitable praxis. Equitable science teaching challenges belief systems but allows for practices to change organically and without prescription. Implications for policy makers, teacher educators, administrators and teachers are discussed. / Urban Education

School-level Factors in Public High Schools that help Raise Academic Achievement for Black Males

Jones, Sharon Lynn 19 October 2020 (has links)
This qualitative research study explored the leadership perceptions of high school administrators who have been successful in raising academic achievement for Black males. Utilizing semi-structured interviews which served as the primary data source, this study aimed to uncover specific school-level factors that were being optimized in public high schools to help increase graduation rates for Black male students. In addition, a review of school documents acted as secondary data sources and offered more detailed views about the case studies. After thorough analysis of the data, the findings revealed five factors that the high school administrators were optimizing better support their Black male learners: 1) hiring Black males, 2) the staff, 3) school activities, 4) collaborations with community partners, and 5) formal and informal methods of offering positive feedback and special recognition. These five factors were found as having the greatest influence on the academic achievement of the males. Overall, the study's findings aligned with earlier research on student achievement. Based on the findings, it was clear that the five factors promoted a certain degree of academic achievement independently. However, the researcher posits that, if implemented simultaneously, the five factors are likely to build a greater network of support for Black male high school students that will help boost achievement that is converted to increased graduation rates. Thus, implications for practice for other high school administrators as well as recommendations for future research emerged from the findings of this study. / Doctor of Education / This qualitative research study explored the leadership perceptions of high school administrators who have been successful in raising academic achievement for Black males.

Les effets d'une formation continue tels que perçus par des enseignants sur leur sentiment d'efficacité et de leurs pratiques de l'enseignement des sciences au primaire

Louis, Natacha 05 1900 (has links)
L'enseignement des sciences est souvent perçu, par les enseignants, comme une discipline complexe à enseigner. La formation continue permet de modifier cette perception en offrant de l'accompagnement pédagogique pour développer les pratiques d'enseignement des sciences et rehausser le sentiment d'efficacité des enseignants. Cette recherche s'intéresse aux effets d'une formation continue sur le sentiment d'efficacité des enseignants et leur enseignement des sciences au primaire. L'approche choisie est celle d'une recherche qualitative et la méthode est celle de l'étude de cas, de type exploratoire. Dans le cadre de cette recherche, six enseignants ayant suivi divers programmes de formation continue afin de développer leur pratique d'enseignement des sciences ont été rencontrés. Des entrevues et des observations (grilles basées sur l'échelle du sentiment d'efficacité des enseignants (STEBI)) sont utilisées pour la collecte de données. Les résultats de l'analyse de données indiquent, dans un premier temps, que les enseignants rencontrés perçoivent que la formation continue a des effets positifs sur leur sentiment d'efficacité, notamment en ce qui a trait à la première dimension relative à la compétence à enseigner les sciences (CE). Dans un deuxième temps, la comparaison des données des pratiques déclarées et des pratiques effectives révèlent l'apport considérable de l'engagement du milieu et de la collaboration des pairs sur le développement de la deuxième dimension relative à l'efficacité de l'enseignement (EE). / Primary teachers have difficulties with science teaching and as a consequence, this subject matter is often neglected. Teacher development in this discipline can contribute to change in teacher practices and impact on teachers beliefs towards science. This study explores the effect of professionnal development in science, given over a period of time, on teacher practices and self-efficacy beliefs. A qualitative approach using an exploratory case study was chosen for this research. For that purpose, several data collection tools such as interviews and observations, using the Science Teaching Efficacy Belief Instrument (STEBI) were chosen. The results indicate that the six teachers participating in the study perceive professional development in science as having a positive effect on their self-efficacy beliefs (especially on their personal science teaching efficacy (PSTE)). In addition, the comparison of the data collected from the interviews and the observations suggests that teachers who participate in professional development as a group have a high personal science teaching efficacy (PSTE), but also a higher science teaching outcome expectancy (STOE).
