Thesis advisor: Laura M. O'Dwyer / Youth civic participation is at alarmingly low levels. In 2014, nearly 80% of eligible 18-29 year-olds did not vote in the midterm election (CIRCLE, 2014). Other forms of civic engagement are also at starkly low levels: less than one in ten 18-29 year-olds report contacting a public official, boycotting a product, or frequently expressing political opinions on the internet (U.S. Census Bureau, 2014). Historically, schools have been tasked with preparing students with the knowledge and skills to be active democratic citizens. However, few studies have examined the role of teachers in fostering students' civic knowledge and skills. This study used data from the 2010 National Assessment of Educational Progress (NAEP) 8th grade civics assessment to analyze the relationships between teacher participation in professional learning, use of interactive instructional practices, and student achievement in civics. Participation in professional learning significantly predicted both interactive instruction and student achievement: a one standard deviation increase in professional learning was associated with a predicted .32 standard deviation increase in interactive instructional practices, and a predicted .045 standard deviation increase in student achievement. There was no significant difference between more traditional and communities of practice based forms of professional development in their relationships with interactive instructional practices and student civic achievement. Interactive instructional practices were also significantly associated with increases in student achievement on NAEP civics, but the effect size was small: a one standard deviation increase in interactive instruction was related to a predicted .03 standard deviation increase in student achievement. Moreover, the relationship between interactive instruction and student achievement was curvilinear; high levels of interactive instruction were associated with decreases in student achievement. The study did not find any evidence that teacher participation in professional learning increased the effectiveness of interactive instructional practices. / Thesis (PhD) — Boston College, 2015. / Submitted to: Boston College.

CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / Este trabalho apresenta uma sequÃncia de atividades interativas com o software de matemÃtica dinÃmica GeoGebra, abrangendo todos os principais tÃpicos de geometria analÃtica para o ensino mÃdio. As atividades sÃo abordadas aqui em forma de tutorial para que mesmo os usuÃrios que nÃo tem familiaridade com o software possam executÃ-las sem dificuldades. O trabalho ressalta tambÃm as vantagens de se fazer uso de recursos tecnolÃgicos como o computador e softwares de geometria e matemÃtica dinÃmica no ensino de matemÃtica trazendo um relato positivo de uma experiÃncia vivida em uma escola de ensino mÃdio do municÃpio de Morada Nova - CE. A sequÃncia de atividades aqui mencionadas parte de atividades simples de cada tÃpico de geometria analÃtica para o ensino mÃdio e passa para problemas essencialmente de geometria euclidiana plana que sÃo solucionados usando o mÃtodo analÃtico, adotando um sistema de coordenadas apropriado, permitindo a participaÃÃo ativa dos alunos no seu aprendizado por construÃrem e manipularem os objetos estudados com o GeoGebra e usarem um raciocÃnio diferente ao solucionar o problema. Por fim surgem algumas atividades de lugares geomÃtricos que possibilitam ao aluno modificar figuras e verificar a preservaÃÃo de suas propriedades. Esta proposta de trabalho à uma tentativa de prover para o professor um meio adicional e diferenciado para o ensino de geometria analÃtica no ensino mÃdio que pode ser fonte de motivaÃÃo para o aluno e que o permita perceber de forma mais clara a forte relaÃÃo entre a Ãlgebra e a geometria. / This paper presents a sequence of interactive activities with the dynamic mathematics software GeoGebra, covering all major analytical topics for high school geometry. The activities are addressed here in the form of tutorial so that even users who are not familiar with the software can run them without difficulty. The work also highlights the advantages of making use of technological resources such as computer software and dynamic geometry and mathematics in mathematics teaching bringing a positive account of lived in a high school in the city of Morada Nova - CE Experience. The sequence of activities mentioned here arises from simple activities of every topic of analytic geometry for high school and move on to problems essentially flat Euclidean geometry that are solved using the analytical method, adopting an appropriate system of coordinates, allowing the active participation of students in their learning by building and manipulating the objects studied with GeoGebra and use a different reasoning to solve the problem. Finally some activities arise loci that allow the student to modify figures and verify the preservation of their property. The proposed work is an attempt to provide for an additional teacher and differential for teaching analytic geometry in high school that can be a source of motivation for the student and that allows to realize more clearly the strong relationship between algebra through and geometry.

La presente investigación denominada “Actividades interactivas con Jclic-Hot potatoes para lograr la competencia resuelve problemas de movimiento, forma y localización”, de enfoque cuantitativo, y tipo cuasi experimental, tuvo el objetivo de determinar en qué medida influyen las actividades interactivas ut supra, en el logro de la competencia matemática mencionada, en alumnas de 4° “B” de Educación Secundaria de la Institución Educativa Sara Antonieta Bullón Lamadrid de la ciudad de Lambayeque, en el año 2019, aplicando el modelo de diseño instruccional ADDIE El estudio consideró una muestra estadística conformada por los grupos experimental y control con 30 discentes de cuarto grado, pertenecientes a una población de 210 alumnas. Se aplicó el instrumento ficha de registro y la data obtenida fue procesada mediante el estadístico T Student, interpretándose y discutiéndose, a la luz del marco teórico. Finalmente, se demostró la hipótesis que Las actividades interactivas con Jclic-Hot Potatoes influyen en el logro de la competencia Resuelve Problemas de Movimiento, Forma y Localización en estudiantes de 4° “B” de educación secundaria de la entidad educativa Sara Antonieta Bullón Lamadrid de la ciudad de Lambayeque, en el año 2019; concluyéndose con la pertinencia del empleo de los softwares educativos mencionados. / The present investigation called "Interactive activities with Jclic-Hot potatoes to achieve competence solves problems of movement, shape and location", of a quantitative approach, and quasi-experimental type, had the objective of determining to what extent the activities influence interactive ut supra, in the achievement of the aforementioned mathematical competence, in students of 4th "B" of Secondary Education of the Sara Antonieta Bullón Lamadrid Educational Institution of the city of Lambayeque, in the year 2019, applying the ADDIE instructional design model The study considered a statistical sample made up of the experimental and control groups with 30 fourth grade students, belonging to a population of 210 female students. The registration form instrument was applied and the data obtained was processed using the T Student statistic, interpreting and discussing it, in light of the theoretical framework. Finally, the hypothesis was demonstrated that the interactive activities with JclicHot Potatoes influence the achievement of the competence Solve Problems of Movement, Shape and Location in students of 4th "B" of secondary education of the educational entity Sara Antonieta Bullón Lamadrid de the city of Lambayeque, in the year 2019; concluding with the relevance of the use of the mentioned educational software.
