O rádio na educação brasileira

The scenario that outlines this research project is characterized by the centrality of ICT on society and the necessity of having them embedded on education, both face-to-face and distance learning. Amongst the available ICT, the medium radio has been chosen due to its popularity within Brazilian society, as well as its 90 years of initiatives applied on education. Although the radio seems to be historically useful to education, it has been supporting more conservative approaches, such as teaching centred practices, simplytransmitted lessons and assessment based on memorization. On the other hand, Brazilian educational system has been changed since the early 90s, and those reforms brought new challenges to the radio on education, such as training critical listeners, concerned citizens, people with aesthetic sensibility, ethical standards etc. Thus, a systematic assessment of the real educational possibilities of the radio is even more necessary. This research projectaims to retrieve the most prominent educational initiatives using the radio, connecting them to the Brazilian regulatory framework on Education. The methodology consists of desk research and official documents analyses.

Teacher-learning process based on an immersive and interactive environment

This paper explores the benefits of using immersive and interactive multiprojection environments (CAVE) to visualize molecules, and how it improves users’ understanding. We have proposed and implemented a tool for teachers to manipulate molecules and another to edit molecules and assist students at home. The contribution of the present research project are these tool that allows investigating structures, properties and dynamics of a molecular system which are extremely complex and comprises millions of atoms. The experience is enriched through multimedia information associated with parts of the model; for example, videos and text can be linked to specific molecule, demonstrating some detail. This solution is based on a teaching-learning process.

Reading as a Learning Strategy for Mathematics

In this action research study of 55 sophomore and junior students in my Algebra II/Trigonometry classrooms, I investigated a reading strategy of learning mathematics. Students were given background information about reading and explored the benefits of reading for themselves. Next, students were taught to read their textbook, analyzing one section of the textbook at a time. Throughout the research project, students were given reading guides to fill out during class with whole class discussion following the reading time. I discovered that students are able to read a mathematics textbook with understanding and students who are gone for activities can learn independently. Teacher observations, student surveys, and student interviews provide quantitative evidence of increased student understanding and achievement. As a result of this research, I plan to continue utilizing the reading guides and incorporating reading as a method of learning mathematics within my classrooms.

Collaboration as a Foundation for the Project Approach in Family Child Care

Supporting children's curiosity was considered important at my family child care home. How could we best achieve this? As my assistant caregiver Deb and 1 attended professional development workshops, we began to wonder if the project approach (Helm & Katz 2001) would be an effective means of supporting inquiry and collaborative learning. Before we would commit ourselves, we wanted to learn more. We had many questions. Just what is the project approach? What does it look like? How will it support children's learning? What do we need to be successful with it? The literature suggested many examples of successful projects at child care centers and preschools (Breig-Allen et al. 1998; Harkem: 1999; Beneke 2000; Glassman & Whaley 2000). Our challenge was how to adapt the project approach to our home child care situations.

DIGITAL LIBRARIES AND LEARNING OBJECTS REPOSITORIES

Discusses the technological changes that affects learning organizations as well as the human, technical, legal and sustainable aspects regarding learning objects repositories creation, maintenance and use. It presents concepts of information objects and learning objects, the functional requirements needed to their storage at Learning Management Systems. The role of Metadata is reviewed concerning learning objects creation and retrieval, followed by considerations about learning object repositories models, community participation/collaborative strategies and potential derived metrics/indicators. As a result of this desktop research, it can be said that not only technical competencies are critical to any learning objects repository implementation, but it urges that an engaged community of interest be establish as a key to support a learning object repository project. On that matter, researchers are applying Activity Theory (Vygostky, Luria y Leontiev) in order to seek joint perceptions and actions involving learning objects repository users, curators and managers, perceived as critical assets to a successful proposal.

Classificazione a faccette di obiettivi formativi dell’insegnamento universitario, nelle discipline umanistiche in Austria, Germania, Italia e Regno Unito

Il processo di riforma a carattere europeo che ha condotto alla nascita di uno Spazio Europeo dell’Istruzione Superiore ha conosciuto diverse tappe fondamentali, fra cui, per esempio, la ripartizione in cicli e l’adozione dei crediti ECTS. Una di queste tappe, ossia il passaggio da una pianificazione della didattica basata sui contenuti ad una basata sui risultati dell’apprendimento, ricopre un ruolo di primo piano nel presente progetto di dottorato. Lo studio qui descritto ha esaminato, da un punto di vista sintattico e semantico, un campione di obiettivi e risultati dell’apprendimento di insegnamenti di alcuni corsi di laurea di primo e secondo ciclo, delle scienze umanistiche, in Austria, Germania, Italia e Regno Unito. L’obiettivo del progetto è proporre uno schema per una classificazione a faccette di obiettivi dell’apprendimento denominato FLOC. Tale schema è adottato per classificare gli obiettivi dell’apprendimento di quattro contesti linguistico-culturali (nei paesi summenzionati), dando vita a FLOC-AT, FLOC-DE, FLOC-IT e FLOC-EN. Queste quattro classificazioni forniscono inoltre il contesto per un’analisi contrastiva multilingue fra unità di obiettivi di apprendimento.

Effect of implementing project-based education in high school physics : file folder bridge engineering

Project-based education and portfolio assessments are at the forefront of educational research. This research follows the implementation of a project-based unit in a high school physics class. Students played the role of an engineering firm who designed, built and tested file folder bridges. The purpose was to determine if projectbased learning could improve student attitude toward science and related careers like engineering. Teams of students presented their work in a portfolio for a final assessment of the process of designing, building and testing their bridges.

Comparison of the effects of inquiry-based cooperative learning and demonstrations in science education

The reported research project involved studying how teaching science using demonstrations, inquiry-based cooperative learning groups, or a combination of the two methods affected sixth grade students’ understanding of air pressure and density. Three different groups of students were each taught the two units using different teaching methods. Group one learned about the topics through both demonstrations and inquirybased cooperative learning, whereas group two only viewed demonstrations, and group three only participated in inquiry-based learning in cooperative learning groups. The study was designed to answer the following two questions: 1. Which teaching strategy works best for supporting student understanding of air pressure and density: demonstrations, inquirybased labs in cooperative learning groups, or a combination of the two? 2. And what effect does the time spent engaging in a particular learning experience (demonstrations or labs) have on student learning? Overall, the data did not provide sufficient evidence that one method of learning was more effective than the others. The results also suggested that spending more time on a unit does not necessarily equate to a better understanding of the concepts by the students. Implications for science instruction are discussed.

Improving learning by connecting chemistry curriculum to students' experiences

The purpose of the study was to design, implement, and assess the effects of a teaching unit about fuel sources and chemical energy on students’ learning. The unit was designed to incorporate students’ experiences in a way that was aligned with the Michigan High School Content Expectations. The study was completed with all of the students taking General Chemistry in a rural Michigan high school in the 2010-11 school year. There were 138 participants total. The participants were mostly Caucasian and the majority were in the 11th grade. Of these, 77 constituted the experimental group and were taught the unit. The additional 61 participants in the control group were given the posttest only. Data was derived from the results of pre/post tests, final assessment projects, and the researcher’s observations. A pretest that contained questions about the fuel sources was administered at the beginning of the unit. An identical posttest was administered at the completion of the unit. A final assessment project required students to choose the best fuel source for the area, and support their opinion with facts and data from their research or the learning activities and labs performed in class. The results of the study revealed that the teaching unit did produce significant learning gains in the experimental group. The results also indicated that the teaching unit added value to the current General Chemistry curriculum by expanding what students were learning. The instructional goals of the unit were aligned with the Michigan High School Content Expectations. The results also revealed that the students were able to learn to support their thinking and decisions with explanations based on the data and labs. These are essential science literacy skills. The study supported the view that connecting the required curriculum with students’ experiences and interests was effective, and that students can learn important science literacy skills, such as providing support for arguments and communicating scientific explanations, when given adequate teacher support.

E-Learning 2.0 in hydraulic engineering education

In this contribution the experiences with e-Learning 2.0 applications by using a Wiki for the education in hydraulic engineering are shown. Up to now important information for the students has been prepared by the instructor. For this project the students were asked to collaborate and search on their own for the information they needed. Therefore a Wiki-system was used. For the engineering practice a self dependent realisation of tasks is an important requirement which students should be prepared for. With the help of online communication there should be shown the possibilities for students for working together in an interdisciplinary team. The positive experiences as well as the results of the evaluation of this project plead for a continuation of the application of e-Learning 2.0 for education. The comparison of results of tests without using Wiki and with using Wiki shows a qualitative tendency of better marks. In this contribution we present the application of Wiki in hydraulic engineering but the results can also be used for other engineering disciplines.

Software Engineering and eLearning: The MuSofT Project

eLearning supports the education in certain disciplines. Here, we report about novel eLearning concepts, techniques, and tools to support education in Software Engineering, a subdiscipline of computer science. We call this "Software Engineering eLearning". On the other side, software support is a substantial prerequisite for eLearning in any discipline. Thus, Software Engineering techniques have to be applied to develop and maintain those software systems. We call this "eLearning Software Engineering". Both aspects have been investigated in a large joint, BMBF-funded research project, termed MuSofT (Multimedia in Software Engineering). The main results are summarized in this paper.

Stud.IP and ILIAS in an EU-Funded Project for the Middle East

In autumn 2005 InWEnt (Internationale Weiterbildung und Entwicklung/Capacity Building International gGmbH) on behalf of the EU invited to tender for three web based trainings (WBT). The precondition: either the open-source-platform Stud.IP or ILIAS should be used. The company data-quest decided not to offer the use of either Stud.IP or ILIAS, but both in combination - and won the contract. Several month later, the new learning environment with the combined powers of Stud.IP and ILIAS was ready to serve WBT-participants from all over the world. The following text describes the EU-Project "Efficient Management of Wastewater, its Treatment and Reuse in the Mediterranean Countries" (EMWater), the WBT concept and the experiences with the new Stud.IP-ILIAS-interface.
