Project Proposals Development – Entrepreneurship and Reflection in Teaching Information Technology

This work presents a model for development of project proposals by students as an approach to teaching information technology while promoting entrepreneurship and reflection. In teams of 3 to 5 participants, students elaborate a project proposal on a topic they have negotiated with each other and with the teacher. The project domain is related to the practical application of state-of-theart information technology in areas of substantial public interest or of immediate interest to the participants. This gives them ample opportunities for reflection not only on technical but also on social, economic, environmental and other dimensions of information technology. This approach has long been used with students of different years and programs of study at the Faculty of Mathematics and Informatics, Plovdiv University “Paisiy Hilendarski”. It has been found to develop all eight key competences for lifelong learning set forth in the Reference Framework and procedural skills required in real life.

The role of temporal synchrony in the facilitation of perceptual learning during prenatal development

This study explored the critical features of temporal synchrony for the facilitation of prenatal perceptual learning with respect to unimodal stimulation using an animal model, the bobwhite quail. The following related hypotheses were examined: (1) the availability of temporal synchrony is a critical feature to facilitate prenatal perceptual learning, (2) a single temporally synchronous note is sufficient to facilitate prenatal perceptual learning, with respect to unimodal stimulation, and (3) in situations where embryos are exposed to a single temporally synchronous note, facilitated perceptual learning, with respect to unimodal stimulation, will be optimal when the temporally synchronous note occurs at the onset of the stimulation bout. To assess these hypotheses, two experiments were conducted in which quail embryos were exposed to various audio-visual configurations of a bobwhite maternal call and tested at 24 hr after hatching for evidence of facilitated prenatal perceptual learning with respect to unimodal stimulation. Experiment 1 explored if intermodal equivalence was sufficient to facilitate prenatal perceptual learning with respect to unimodal stimulation. A Bimodal Sequential Temporal Equivalence (BSTE) condition was created that provided embryos with sequential auditory and visual stimulation in which the same amodal properties (rate, duration, rhythm) were made available across modalities. Experiment 2 assessed: (a) whether a limited number of temporally synchronous notes are sufficient for facilitated prenatal perceptual learning with respect to unimodal stimulation, and (b) whether there is a relationship between timing of occurrence of a temporally synchronous note and the facilitation of prenatal perceptual learning. Results revealed that prenatal exposure to BSTE was not sufficient to facilitate perceptual learning. In contrast, a maternal call that contained a single temporally synchronous note was sufficient to facilitate embryos’ prenatal perceptual learning with respect to unimodal stimulation. Furthermore, the most salient prenatal condition was that which contained the synchronous note at the onset of the call burst. Embryos’ prenatal perceptual learning of the call was four times faster in this condition than when exposed to a unimodal call. Taken together, bobwhite quail embryos’ remarkable sensitivity to temporal synchrony suggests that this amodal property plays a key role in attention and learning during prenatal development.

Group presence in virtual worlds: Supporting collaborative e-learning

Even though e-learning endeavors have significantly proliferated in recent years, current e-learning technologies provide poor support for group-oriented learning. The now popular virtual world's technologies offer a possible solution. Virtual worlds provide the users with a 3D - computer generated shared space in which they can meet and interact through their virtual representations. Virtual worlds are very successful in developing high levels of engagement, presence and group presence in the users. These elements are also desired in educational settings since they are expected to enhance performance. The goal of this research is to test the hypothesis that a virtual world learning environment provides better support for group-oriented collaborative e-learning than other learning environments, because it facilitates the emergence of group presence. To achieve this, a quasi-experimental study was conducted and data was gathered through the use of various survey instruments and a set of collaborative tasks assigned to the participants. Data was gathered on the dependent variables: Engagement, Group Presence, Individual Presence, Perceived Individual Presence, Perceived Group Presence and Performance. The data was analyzed using the statistical procedures of Factor Analysis, Path Analysis, Analysis of Variance (ANOVA) and Multivariate Analysis of Variance (MANOVA). The study provides support for the hypothesis. The results also show that virtual world learning environments are better than other learning environments in supporting the development of all the dependent variables. It also shows that while only Individual Presence has a significant direct effect on Performance; it is highly correlated with both Engagement and Group Presence. This suggests that these are also important in regards to performance. Developers of e-learning endeavors and educators should incorporate virtual world technologies in their efforts in order to take advantage of the benefit they provide for e-learning group collaboration.

Relatório de Estágio

O percurso de formação para a docência que teve início com a Licenciatura em Educação Básica e termina agora com a conclusão do Mestrado em Ensino do 1º e 2º ciclos do Ensino Básico culmina com a realização e defesa do presente relatório cujo objetivo é demonstrar, por meio da análise e reflexão, o trabalho realizado pela mestranda no âmbito da sua intervenção educativa em contexto de Prática Educativa Supervisionada (PES). A intervenção educativa foi um percurso onde foram tomadas opções sustentadas e com intenção pedagógica, numa articulação entre a teoria e a prática, com uma postura permanentemente crítica e reflexiva das práticas com o intuito de as melhorar. O percurso desenvolveu-se numa perspetiva investigativa com características de investigação-ação que culminou na realização de um projeto investigativo implementado nos contextos, percecionando-se, deste modo, a importância da necessidade permanente do professor-investigador para que possa investigar as suas práticas educativas, de forma a melhorá-las e transformá-las. A supervisão teve um papel fundamental no decorrer de todo o processo através do acompanhamento por parte dos supervisores institucionais, contanto com o apoio e colaboração dos professores cooperantes e o trabalho colaborativo com o par pedagógico, permitindo melhorar práticas e contribuir para o crescimento pessoal e profissional da mestranda. O relatório de estágio surge, desta forma, como retrato do percurso desenvolvido, que ilustra o início da construção do que é ser professor e espelha um crescimento pessoal e profissional que se vai desenvolver futuramente

Relatório de Estágio

A Prática Educativa Supervisionada representa, sem dúvida, a etapa mais aguardada pelos estudantes que se formam para serem professores, pois este é um momento recheado de expectativas e descobertas da profissionalidade docente. Por conseguinte, o presente relatório de estágio pretende espelhar o percurso evolutivo da mestranda ao longo dessa prática pedagógica. A passagem pelas escolas ficou marcada por uma postura crítica e reflexiva perante as opções pedagógicas tomadas, sendo que estas resultaram sempre de uma articulação entre os quadros teóricos e práticos de cada área disciplinar. A supervisão, processo crucial durante o estágio, é considerada pela professora estagiária como um momento de acompanhamento e orientação da ação educativa por parte dos supervisores institucionais. A par deste processo foi sempre visível um trabalho colaborativo com o par pedagógico e com os professores cooperantes, com o principal objetivo de atingir novos e melhores modos de agir, ancorando-se, assim, nos pilares da metodologia de investigação-ação. O trajeto construído pela formanda é o retrato de uma experiência de desenvolvimento pessoal e profissional, tendo, porém, a convicção de que, apesar de este relatório marcar o término de um ciclo de estudos inicial, há muito mais para aprender e construir.

Engaging marketing students : student operated businesses in a simulated world

Engaged students are committed and more likely to continue their university studies. Subsequently, they are less resource intensive from a university’s perspective. This article details an experiential second-year marketing course that requires students to develop real products and services to sell on two organized market days. In the course, students participate as both consumers and marketers in a simulated world. The current article explores the effectiveness of this experiential assessment in terms of its ability to engage students. Comparing student engagement to a traditional lecture course and National Survey of Student Engagement benchmarks, the results suggest that the use of a simulated marketplace is capable of engaging students. Specifically, the assessment reported encourages more active learning and collaboration, is more academically challenging, and permits more student–faculty interaction than a traditional lecture-based course. The course structure outlined in this article permits the dynamics of a live marketing environment to be introduced into the classroom. The authors provide practical advice for educators seeking to design and implement engaging pedagogy.

The research focus of this study is imagery-based learning aimed at discovering an authentic way of public speaking in the context of transformative learning. The experiences of the participants in this learning process were also a subject of study. This learning process consisted of both guided and independent imagery-based training techniques. Critical reflection plays an important role in transformative learning. Actions, and interpretations and assumptions guiding them, are recognised and subjected to critical reflection. The goal of the learning process is an authentic and wide meaning perspective. Imagery-based training benefits from the gap between the new and the old experience of public speaking, and this is utilised as an activating factor for learning. The study is qualitative, looking at the imagery learning process and its outcomes from the subjective viewpoint of the participants personal experience. The imagery training acted as an intervention in the process of learning authentic public performance. The number of participants in this study was ten, five men and five women from four different working backgrounds. There were 80 individual training sessions, each attended by one person. The author conducted the imagery-based training. For each participant the learning process took roughly nine months. The research data consisted in the answers to questions in writing, diary entries, interviews and researcher notes. The data gathered by these methods was compiled into a personal report for each participant. The learners perceived authentic public speaking performance at the end of the learning process as wider, more flexible and more genuine than at the start of the training. Authenticity was defined through an internal process of becoming aware instead of some external characteristics. The learners understood the process of imagery learning as training for public performance and as an opportunity to become familiar with one s own personal way of acting and with one s own attitudes. They also perceived it as a tool that enabled the observation of personal experiences from different points of view. The learners reflected on ways of acting related to public speaking as well as on contributing factors to performance anxiety during the imagery learning process. Towards the end of the learning process, even critical reflection took place. The learners were categorized into three groups according to differences in their learning processes: the participants, the actors and the critical reflectors. This grouping reflected the relative amount of transformation in their learning processes. The participants became aware of their actions and assumptions. They took part in guided training sessions only. Worries in private life also had some consequences to their training in imagery learning. Apart from than becoming more conscious, the learning process did not yield much difference to the public speaking experiences of the participants. The actors attended both guided imagery training sessions and did individual training on their own. They became aware of their assumptions and their ways of acting. The encounter of the new and the old way of acting stimulated their learning. The actors advanced towards their own goals or even achieved them. The critical reflectors recognised their own assumptions and ways of acting and started to reflect critically on their own attitudes, as well as external attitudes and interpretations. Their assumptions, interpretations and experiences of public performance started to change in a positive direction. The learning process of the critical reflectors was functioning as a transformative process. This learning process revealed old assumptions hindering learning and old ways of acting resulting from these assumptions, thus opening up an opportunity for critical reflection and transformation.

Laminar Cortical Dynamics of 3D Surface Perception: Stratification, transparency, and Neon Color Spreading

How does the laminar organization of cortical circuitry in areas VI and V2 give rise to 3D percepts of stratification, transparency, and neon color spreading in response to 2D pictures and 3D scenes? Psychophysical experiments have shown that such 3D percepts are sensitive to whether contiguous image regions have the same relative contrast polarity (dark-light or lightdark), yet long-range perceptual grouping is known to pool over opposite contrast polarities. The ocularity of contiguous regions is also critical for neon color spreading: Having different ocularity despite the contrast relationship that favors neon spreading blocks the spread. In addition, half visible points in a stereogram can induce near-depth transparency if the contrast relationship favors transparency in the half visible areas. It thus seems critical to have the whole contrast relationship in a monocular configuration, since splitting it between two stereogram images cancels the effect. What adaptive functions of perceptual grouping enable it to both preserve sensitivity to monocular contrast and also to pool over opposite contrasts? Aspects of cortical development, grouping, attention, perceptual learning, stereopsis and 3D planar surface perception have previously been analyzed using a 3D LAMINART model of cortical areas VI, V2, and V4. The present work consistently extends this model to show how like-polarity competition between VI simple cells in layer 4 may be combined with other LAMINART grouping mechanisms, such as cooperative pooling of opposite polarities at layer 2/3 complex cells. The model also explains how the Metelli Rules can lead to transparent percepts, how bistable transparency percepts can arise in which either surface can be perceived as transparent, and how such a transparency reversal can be facilitated by an attention shift. The like-polarity inhibition prediction is consistent with lateral masking experiments in which two f1anking Gabor patches with the same contrast polarity as the target increase the target detection threshold when they approach the target. It is also consistent with LAMINART simulations of cortical development. Other model explanations and testable predictions will also be presented.

Formando o cidadão desde o jardim-de-infância: o contributo das práticas de avaliação das aprendizagens dos educadores de infância em colaboração com a família

A presente investigação procura compreender o fenómeno complexo e dinâmico que é a avaliação das aprendizagens das crianças em colaboração com a família na Educação Pré-Escolar (EPE) como forma de potenciar o desenvolvimento de competências pelas crianças. Assim, e recorrendo a um estudo de caso com uma componente de investigação-acção, pretende-se (i) compreender as concepções e práticas de avaliação de aprendizagens na EPE desenvolvidas por um grupo de educadores de uma Instituição Privada de Solidariedade Social da região centro do país e (ii) potenciar, através de formação em contexto que contemple o desenvolvimento de estratégias inerentes a uma avaliação das aprendizagens em colaboração com a família das crianças, o desenvolvimento profissional dos educadores de infância neste âmbito, proporcionando experiências educativas que levem as crianças a desenvolver um conjunto de competências inerentes à nova natureza dos saberes básicos de todos os cidadãos do séc. XXI. Tomando como ideias base da investigação a concepção (i) da criança enquanto cidadão (Prout, 2005; Vasconcelos, 2009) e (ii) da família enquanto primeira e principal educadora das crianças (Steves, Hough & Nurs, 2002), a investigação foi desenvolvida em quatro fases: Fase I – Formulação de um referencial de competências para a EPE inerentes à nova natureza dos saberes básicos do séc. XXI e seu processo de transferibilidade e credibilidade; Fase II – Diagnóstico das concepções dos participantes da investigação sobre avaliação das aprendizagens na EPE e colaboração Instituição/Família; Fase III – Construção e implementação de um programa de formação para educadores de infância; Fase IV – Avaliação do impacte do programa de formação nas concepções e práticas de avaliação das aprendizagens dos educadores de infância. A fase I centra-se na formulação de um referencial de competências transversais para a EPE inerentes à nova natureza dos saberes básicos do séc. XXI (Cachapuz, Sá-Chaves & Paixão, 2004) e no seu processo de transferibilidade e credibilidade através da reflexão/discussão do respectivo referencial com um painel de especialistas e profissionais. Identificaram-se quatro competências transversais a serem desenvolvidas pelas crianças centradas nas dimensões do aprender a aprender, aprender a comunicar e a expressar-se, aprender a ser e estar e aprender a reflectir. A fase II incide no diagnóstico das concepções de avaliação das aprendizagens na EPE e de colaboração Instituição/Família dos 6 educadores de infância, 17 pais e 17 crianças participantes no estudo, recorrendo a entrevistas, à análise documental e à observação de práticas. A análise dos dados recolhidos demonstra que é necessário recuperar um verdadeiro discurso didáctico e educativo da avaliação das aprendizagens, deixando de a conceber como sinónimo de medida e de objectividade e melhorando as práticas de avaliação de VII modo a potenciar o desenvolvimento de competências pelas crianças. A fase III preenche-se na construção e implementação de um programa de formação, creditado e correspondente a 50 horas, para educadores de infância sobre avaliação de competências na EPE em colaboração com a família. O programa de formação foi desenvolvido a partir (i) das concepções diagnosticadas, (ii) dos indicadores da investigação em formação contínua e em avaliação na EPE e (iii) de um modelo de desenvolvimento profissional baseado na reflexão, na observação e supervisão e na investigação-acção (Shön, 1992; Alarcão, 2000; Roldão, 2008; Cadório & Simão, 2011). Os indicadores obtidos demonstram que o programa de formação contribuiu para o enriquecimento profissional dos formandos ao nível da (re)construção de conhecimento, da reflexão constante e colaborativa sobre as práticas de avaliação, da mudança de atitudes e práticas de avaliação das aprendizagens e na compreensão mais profunda da complexidade, diversidade e necessidade de cada criança. Além disso, os indicadores obtidos também evidenciam a importância de uma avaliação das aprendizagens em colaboração com os pais das crianças para o desenvolvimento progressivo das competências transversais para a EPE e, consequentemente, para a obtenção de sucesso educativo. A fase IV consiste na avaliação do impacte do programa de formação nas concepções e práticas avaliativas dos educadores de infância através de, à semelhança da fase II, entrevistas aos 6 educadores de infância, aos 17 pais e às 17 crianças, à análise documental e à observação de práticas. Os resultados obtidos demonstram que o programa de formação teve impacte nas práticas de avaliação das aprendizagens a nível micro (decisões no interior da sala de actividades) e, mais reduzido, a nível meso (decisões a nível institucional). Os educadores de infância integraram nas suas práticas pedagógicas algumas estratégias avaliativas implementadas durante o programa de formação, consciencializando-se da importância da avaliação na EPE se centrar em procedimentos descritivos com enfoque na actividade da criança e na documentação e registo do trabalho realizado no dia-a-dia e do desenvolvimento de competências de cada criança (Gaustad, 1996; Parente, 2002). Contudo, e no que se refere à colaboração dos pais no processo de avaliação das aprendizagens das crianças, o programa de formação não proporcionou qualquer impacte nas práticas avaliativas dos educadores de infância. Apesar dos discursos transparecerem uma consciencialização da importância da família participar e influenciar a tomada de decisões ao longo do processo de avaliação das aprendizagens (Oliveira-Formosinho & Araújo, 2004), não foram tomadas medidas de mudança de práticas neste sentido, permanecendo os pais das crianças como sujeitos passivos neste processo. Uma visão integradora sobre os resultados obtidos ao longo da presente investigação revela a necessidade de se continuar a investigar e a construir novos caminhos na formação contínua dos educadores de infância de modo a recuperar um verdadeiro discurso educativo da avaliação das aprendizagens com impacte nas práticas pedagógicas e onde a família das crianças surja como parceira num trabalho a desenvolver colaborativamente.

Effectiveness of computer training on attentional skills

This paper presents two studies, both examining the efficacy of a computer programme (Captain's Log) in training attentional skills. The population of interest is the traumatically brain injured. Study #1 is a single-case design that offers recommendations for the second, .larger (N=5) inquiry. Study #2 is an eight-week hierarchical treatment programme with a multi-based testing component. Attention, memory, listening comprehension, locus-of-control, self-esteem, visuo-spatial, and general outcome measures are employed within the testing schedule. Results suggest that any improvement was a result of practice effects. With a few single-case exceptions, the participants showed little improvement in the dependent measures.

The status and barriers to the implementation and continuation of the school gardening projects in Germany, Nigeria and the United States of America

In drawing a conclusion for this study, care must be taken in generalizing findings since the population of students and teachers investigated were limited to certain levels in the different schools and countries. This study recognized some complexity of the factors underlying the status of school gardening instruction and activities in Germany, Nigeria and the U.S. as inadequate time for decision-making in the process of gardening, motivation of teachers and students. This was seen as the major impediments that influenced the status of gardening in the three countries. However, these factors were considered to have affected students’ mode of participation in the school gardening projects. This research finding suggests that the promotion and encouragement of students in gardening activities will promote vegetable production and increasing the numbers of practical farmers. Gardening has the potential to create opportunities for learning in an environment where children are able to experience nature first hand and to use the shared experience for communication (Bowker & Tearle, 2007). Therefore, the need for students to be encouraged to participate in gardening programs as the benefit will not only reduce the rate of obesity currently spreading among youths, but will contribute to the improve knowledge on science subjects. To build a network between community, parents and schools, a parent’s community approach should be used as the curriculum. The community approach will tighten the link between schools; community members, parents, teachers and students. This will help facilitate a better gardening projects implementation. Through a close collaboration, teachers and students will be able to identify issues affecting communities and undertake action learning in collaboration with community organizations to assess community needs and plan the implementation strategies as parents are part of the community. The sense of efficacy is a central factor in motivational and learning processes that govern educational improvement, standard and performance on complex tasks of both teachers and students. Dedication and willingness are the major stimulator and achievement of a project. Through a stimulator and provision of incentives and facilities, schools can achieve the best in project development. Teachers and principals should be aware that students are the lever for achieving the set goals in schools. Failure to understand what students need will result in achieving zero result. Therefore, it is advised that schools focus more on how to lure students to work through proper collaboration with the parents and community members. Principals and teachers should identify areas where students need to be corrected, helping them to correct the problem will enable them be committed in the schools’ programs.

Example General Feedback on Routes to Success Portfolios

This document provides example feedback which has been generated following the marking of a class set of portfolios. It is used as a part of the Routes to Success Module, specifically on the section titled Sustaining Success. Students can read the feedback prior to completing the portfolio to alert them to the possible shortfalls which may occur when they undertake this type of task. The feedback is introduced in the context that the task of completing the portfolio is a developmental one, and that students can expect to learn and improve their performance for this type of task as they develop and refine their skills.
