Thinking over b���learning strategy: the MIPO model approach

This article describes the main research results in a new methodology, in which the stages and strategies of the technology integration process are identified and described. A set of principles and recommendations are therefore presented. The MIPO model described in this paper is a result of the effort made regarding the understanding of the main success features of good practices, in the web environment, integrated in the information systems/information technology context. The initial model has been created, based on experiences and literature review. After that, it was tested in the information and technology system units at higher school and also adapted as a result of four cycles of an actionresearch work combined with a case study research. The information, concepts and procedures presented here give support to teachers and instructors, instructional designers and planning teams ��� anyone who wants to develop effective b���learning instructions.

B-leraning: elemento institucional e operacional de desenvolvimento educativo uma institui����o de ensino superior

Na sua origem o Projecto de Apoio OnLine do ISCAP (PAOL) tinha como principal fonte impulsionadora a necessidade emergente de desenvolver solu����es sustentadas de integra����o das tecnologias como apoio ��s aulas presenciais ministradas na institui����o. Este elemento impulsionador ainda hoje se mant��m como uma das principais alavancas, agora alargada transversalmente nas ��reas de conhecimento da institui����o e na inclus��o das compet��ncias did��ctico-pedag��gicas. Com o desenvolvimento do projecto, ganharam import��ncia crescente as fontes pr��prias de cria����o de conhecimento e de solu����es t��cnicas, capazes de responder aos anseios da comunidade escolar. Este artigo pretende enquadrar e explicitar, atrav��s da mostra de casos pr��ticos e de uma an��lise dos resultados de uso da plataforma Moodle, o percurso seguido pelo projecto, a estrat��gia adoptada e as ac����es implementadas. Abstract Initially ISCAP���s Online Support Project (PAOL), was instigated by the emergent necessity to develop sustainable solutions in order to integrate technologies as a means to support the institution���s traditional in-class lessons. This propulsive element, still valid today as one of the main levers, has now transversally extended into the various knowledge areas within the institution and the inclusion of pedagogic-didactical competences. With the development of the project, the institution���s own sources of knowledge creation and technical solutions capable of answering the needs of the institutions��� community became ever more crucial. This article seeks to frame and explain, by showing practical cases and the analysis of the results as to the use of the learning platform Moodle, the path taken by the project, the strategy adopted and the actions implemented.

Terminologia e b-learning; o regresso de Humpty Dumpry

Este estudo tem por objectivo reflectir sobre o papel da Terminologia na organiza����o conceptual e lingu��stica das ��reas de especialidade. Defender-se-�� que, pela sua natureza hermen��utica, organizadora, harmonizadora e heur��stica, esta ��rea cient��fica poder�� reduzir a complexidade e a fragmenta����o lexical e conceptual que impera no dom��nio dos modelos de educa����o para o Ensino Superior, permitindo ajudar a clarificar a filia����o ideol��gica das v��rias vis��es de ensino, levando deste modo a que o debate seja epistemologicamente transparente. Ser�� focado o caso particular do Blended-Learning, enquanto exemplo de um sub-dom��nio ainda inst��vel, do ponto de vista da sua organiza����o ontol��gica e da sua materializa����o lingu��stica e terminol��gica.

A B-learning strategy for Therapeutics at the Bachelor Level

Background Information:The incorporation of distance learning activities by institutions of higher education is considered an important contribution to create new opportunities for teaching at both, initial and continuing training. In Medicine and Nursing, several papers illustrate the adaptation of technological components and teaching methods are prolific, however, when we look at the Pharmaceutical Education area, the examples are scarce. In that sense this project demonstrates the implementation and assessment of a B-Learning Strategy for Therapeutics using a ���case based learning��� approach. Setting: Academic Pharmacy Methods:This is an exploratory study involving 2nd year students of the Pharmacy Degree at the School of Allied Health Sciences of Oporto. The study population consists of 61 students, divided in groups of 3-4 elements. The b-learning model was implemented during a time period of 8 weeks. Results:A B-learning environment and digital learning objects were successfully created and implemented. Collaboration and assessment techniques were carefully developed to ensure the active participation and fair assessment of all students. Moodle records show a consistent activity of students during the assignments. E-portfolios were also developed using Wikispaces, which promoted reflective writing and clinical reasoning. Conclusions:Our exploratory study suggests that the ���case based learning��� method can be successfully combined with the technological components to create and maintain a feasible online learning environment for the teaching of therapeutics.

Antitumor activity of hierridin B, a cyanobacterial secondary metabolite found in both filamentous and unicellular marine strains

Cyanobacteria are widely recognized as a valuable source of bioactive metabolites. The majority of such compounds have been isolated from so-called complex cyanobacteria, such as filamentous or colonial forms, which usually display a larger number of biosynthetic gene clusters in their genomes, when compared to free-living unicellular forms. Nevertheless, picocyanobacteria are also known to have potential to produce bioactive natural products. Here, we report the isolation of hierridin B from the marine picocyanobacterium Cyanobium sp. LEGE 06113. This compound had previously been isolated from the filamentous epiphytic cyanobacterium Phormidium ectocarpi SAG 60.90, and had been shown to possess antiplasmodial activity. A phylogenetic analysis of the 16S rRNA gene from both strains confirmed that these cyanobacteria derive from different evolutionary lineages. We further investigated the biological activity of hierridin B, and tested its cytotoxicity towards a panel of human cancer cell lines; it showed selective cytotoxicity towards HT-29 colon adenocarcinoma cells.

Electrochemical determination of the herbicide bentazone using a carbon nanotube b-Cyclodextrin modified electrode

An electrochemical sensor has been developed for the determination of the herbicide bentazone, based on a GC electrode modified by a combination of multiwalled carbon nanotubes (MWCNT) with b-cyclodextrin (b-CD) incorporated in a polyaniline film. The results indicate that the b-CD/MWCNT modified GC electrode exhibits efficient electrocatalytic oxidation of bentazone with high sensitivity and stability. A cyclic voltammetric method to determine bentazone in phosphate buffer solution at pH 6.0, was developed, without any previous extraction, clean-up, or derivatization steps, in the range of 10���80 mmolL 1, with a detection limit of 1.6 mmolL 1 in water. The results were compared with those obtained by an established HPLC technique. No statistically significant differences being found between both methods.

B-learning quality: dimensions, criteria and pedagogical approach

Measuring the quality of a b-learning environment is critical to determine the success of a b-learning course. Several initiatives have been recently conducted on benchmarking and quality in e-learning. Despite these efforts in defining and examining quality issues concerning online courses, a defining instrument to evaluate quality is one of the key challenges for blended learning, since it incorporates both traditional and online instruction methods. For this paper, six frameworks for quality assessment of technological enhanced learning were examined and compared regarding similarities and differences. These frameworks aim at the same global objective: the quality of e-learning environment/products. They present different perspectives but also many common issues. Some of them are more specific and related to the course and other are more global and related to institutional aspects. In this work we collected and arrange all the quality criteria identified in order to get a more complete framework and determine if it fits our b-learning environment. We also included elements related to our own b-learning research and experience, acquired during more than 10 years of experience. As a result we have create a new quality reference with a set of dimensions and criteria that should be taken into account when you are analyzing, designing, developing, implementing and evaluating a b-learning environment. Besides these perspectives on what to do when you are developing a b-learning environment we have also included pedagogical issues in order to give directions on how to do it to reach the success of the learning. The information, concepts and procedures here presented give support to teachers and instructors, which intend to validate the quality of their blended learning courses.
