O ensino e aprendizagem da programação de computadores no ensino a distância : uma proposta de instanciação do modelo pedagógico virtual da Universidade Aberta

Hoje em dia o ensino e aprendizagem a distância online de nível universitário é, em grande medida, baseado em estratégias de aprendizagem colaborativa, onde, além de aprender sozinho, os estudantes também participam de ações colaborativas dentro de uma classe virtual. O nível de interação do estudante online representa um fator fundamental para o sucesso do processo de ensino-aprendizagem pois é a base da partilha de informação e construção do conhecimento entre estudantes e professores, enquanto todas as ações e atividades integram um modelo pedagógico comum. Existem muitas diferenças e desafios nas áreas de ensino em termos de instanciação do modelo pedagógico e adoção das estratégias de ensino-aprendizagem, como por exemplo, entre as áreas das ciências sociais e das engenharias. Uma área que atrai especial atenção como um todo é a das ciências da computação (CS), e de forma específica, a da programação de computadores. A programação de computadores exige, em primeiro lugar, o desenvolvimento de um bom raciocínio lógico e uma estratégia de resolução segundo uma abordagem “dividir para conquistar”, onde os principais problemas são divididos em problemas menores que são resolvidos individualmente. A programação exige também uma combinação entre o trabalho individual e em grupo, com elevados níveis de revisão e depuração do código fonte em desenvolvimento. O ensino online de programação de computadores é constituído por estes aspectos, exigindo um elevado grau de interação entre estudantes e entre estudantes e professor. Neste capítulo, vamos discutir e apresentar a nossa experiência no ensino online da programação de computadores com base no modelo pedagógico virtual da Universidade Aberta, e propor a sua instanciação e extensão específica para incluir novas estratégias de aprendizagem colaborativa e uma abordagem construtivista para o processo global de aprendizagem.

Some aspects of grading Java code submissions in MOOCs

Recently, massive open online courses (MOOCs) have been offering a new online approach in the field of distance learning and online education. A typical MOOC course consists of video lectures, reading material and easily accessible tests for students. For a computer programming course, it is important to provide interactive, dynamic, online coding exercises and more complex programming assignments for learners. It is expedient for the students to receive prompt feedback on their coding submissions. Although MOOC automated programme evaluation subsystem is capable of assessing source programme files that are in learning management systems, in MOOC systems there is a grader that is responsible for evaluating students’ assignments with the result that course staff would be required to assess thousands of programmes submitted by the participants of the course without the benefit of an automatic grader. This paper presents a new concept for grading programming submissions of students and improved techniques based on the Java unit testing framework that enables automatic grading of code chunks. Some examples are also given such as the creation of unique exercises by dynamically generating the parameters of the assignment in a MOOC programming course combined with the kind of coding style recognition to teach coding standards.

Computer-aided programming using formally specificed design templates

This paper describes a formal component language, used to support automated component-based program development. The components, referred to as templates, are machine processable, meaning that appropriate tool support, such as retrieval support, can be developed. The templates are highly adaptable, meaning that they can be applied to a wide range of problems. Some of the main features of the language are described, including: higher-order parameters; state variable declarations; specification statements and conditionals; applicability conditions and theories; meta-level place holders; and abstract data structures.

Programming Paradigms in Computer Science Education

Main styles, or paradigms of programming – imperative, functional, logic, and object-oriented – are shortly described and compared, and corresponding programming techniques are outlined. Programming languages are classified in accordance with the main style and techniques supported. It is argued that profound education in computer science should include learning base programming techniques of all main programming paradigms.

Title Model for Computer Networks Optimization

The TCP/IP architecture was consolidated as a standard to the distributed systems. However, there are several researches and discussions about alternatives to the evolution of this architecture and, in this study area, this work presents the Title Model to contribute with the application needs support by the cross layer ontology use and the horizontal addressing, in a next generation Internet. For a practical viewpoint, is showed the network cost reduction for the distributed programming example, in networks with layer 2 connectivity. To prove the title model enhancement, it is presented the network analysis performed for the message passing interface, sending a vector of integers and returning its sum. By this analysis, it is confirmed that the current proposal allows, in this environment, a reduction of 15,23% over the total network traffic, in bytes.

Rough Notes on Programming AVR Microcontrollers in C

These notes follow on from the material that you studied in CSSE1000 Introduction to Computer Systems. There you studied details of logic gates, binary numbers and instruction set architectures using the Atmel AVR microcontroller family as an example. In your present course (METR2800 Team Project I), you need to get on to designing and building an application which will include such a microcontroller. These notes focus on programming an AVR microcontroller in C and provide a number of example programs to illustrate the use of some of the AVR peripheral devices.

Programming internet based DAI applications in Qu-Prolog

This paper presents the unique collection of additional features of Qu-Prolog, a variant of the Al programming language Prolog, and illustrates how they can be used for implementing DAI applications. By this we mean applications comprising communicating information servers, expert systems, or agents, with sophisticated reasoning capabilities and internal concurrency. Such an application exploits the key features of Qu-Prolog: support for the programming of sound non-clausal inference systems, multi-threading, and high level inter-thread message communication between Qu-Prolog query threads anywhere on the internet. The inter-thread communication uses email style symbolic names for threads, allowing easy construction of distributed applications using public names for threads. How threads react to received messages is specified by a disjunction of reaction rules which the thread periodically executes. A communications API allows smooth integration of components written in C, which to Qu-Prolog, look like remote query threads.
