One of the For these reasons, work has started, aiming to identify and possible applications, which usually requires a large set of numerical tests, is related to antenna design. Despite the well- evaluate possible open source programs that can be usefully known advantages offered by open source software, there are employed for the design of antennas and possibly other passive several critical points that restrict its practical application. First, electromagnetic devices such as, for example, filters, couplers, the knowledge of the open source programs is often limited. impedance adapters. The research also aims at finding software Second, by using open source packages it is sometimes not easy to that allows for the pre- and post-processing of data. obtain results with a high level of confidence, and to integrate open Furthermore, it has been decided to consider the possibility of source modules in the production workflow. In the paper, a discussion about open source programs for antenna design is easily integrating the design into the complete production and carried out. -

Supporting Candidates Learning from Home to Prepare for Computer-Based Practical Tests
Supporting candidates learning from home to prepare for computer-based practical tests Supporting candidates learning from home to prepare for the practical tests in Cambridge IGCSE ICT (0417), Cambridge IGCSE (9–1) ICT (0983) and Cambridge International A Level IT (9626) We understand that many centres and candidates are facing challenging times, and that some centres are having to teach practical IT skills remotely. Practical IT skills are a vital part of our IT syllabuses. We assess these skills through formal tests under controlled conditions. To maintain the integrity of the tests, and the value of our qualifications for students, we encourage centres to teach the full syllabus content, whether remotely or face to face. There are currently no adaptations to the practical skills requirements for March or June 2021. However, we understand that candidates do not always have access to proprietary (non-free) software that is licensed through their centre. This may be a significant barrier to candidates practising practical IT skills at home. Using the centre’s licensed software Where candidates are learning remotely, we recommend that you first check your software licences to see if they If your school currently uses proprietary software, you allow candidates to use the software on their home may find that one of the free/open source alternatives computers. Some centres have academic licences that allow listed in the tables on this factsheet allows candidates to this. Other centres are setting up remote access to their practise their skills at home.

Experiences in Using Open Source Software for Teaching Electronic Engineering CAD
Experiences in Using Open Source Software for Teaching Electronic Engineering CAD Dr Simon Busbridge1 & Dr Deshinder Singh Gill School of Computing, Engineering and Mathematics, University of Brighton, Brighton BN2 4GJ [email protected] Abstract Embedded systems and simulation distinguish modern professional electronic engineering from that learnt at school. First year undergraduates typically have little appreciation of engineering software capabilities and file handling beyond elementary word processing. This year we expedited blended teaching through the experiential based learning process via open source engineering software. Students engaged with the entire electronic engineering product creation process from inception, performance simulation, printed circuit board design, manufacture and assembly, to cabinet design and complete finished product. Currently students learn software skills using a mixture of electronic and mechanical engineering software packages. Although these have professional capability they are not available off-campus and are sometimes surprisingly poor in simulating real world devices. In this paper we report use of LTspice, FreePCB and OpenSCAD for the learning and teaching of analogue electronics simulation and manufacture. Comparison of the software options, the type of tasks undertaken, examples of student assignments and outputs, and learning achieved are presented. Examples of assignment based learning, integration between the open source packages and difficulties encountered are discussed. Evaluation of student attitudes and responses to this method of learning and teaching are also discussed, and the educational advantages of using this approach compared to the use of commercial packages is highlighted. Introduction Most educational establishments use software for simulating or designing engineering. Most commercial packages come with an academic licence which restricts access to on-site computers. -

Duas educadoras de infância experientes exploraram o MyPaint com uma mesa de desenho digital com os seus grupos. Durante a experiência, foram recolhidos dados sobre a forma como as crianças se apropriaram do uso do software e sobre dimensões da sua aprendizagem do e com o software. Através de uma análise de conteúdo, diferentes aspetos da experiência foram agrupados em temas: organização da exploração do software nos dois contextos; aprendizagem das crianças sobre desenho e materiais de desenho, com relações entre o uso do software o desenho tradicional; e a colaboração para a aprendizagem. A discussão destaca as dimensões da Pedagogia da Educação de Infância mais relevantes na experiência.

Index Introduction OpenSCAD is a software for creating solid 3D CAD objects. It is free software (http://www.gnu.org/philosophy/free-sw.html) and available for GNU/Linux (http://www.gnu.org/) , MS Windows and Apple OS X. Unlike most free software for creating 3D models (such as the well-known application Blender (http://www.blender.org/) ), OpenSCAD does not focus on the artistic aspects of 3D modelling, but instead focuses on the CAD aspects. So it might be the application you are looking for when you are planning to create 3D models of machine parts, but probably is not what you are looking for when you are more interested in creating computer- animated movies. OpenSCAD is not an interactive modeller. -
