Lecture rm 2
- 1. M. Zeeshan Akbar M.Phil Computer Science Lecture # 2 University of Education, Lahore
- 2. Be considerate to others – switch off mobile phones during lectures, or put them into silent mode.
- 3. Everyday thinking versus good Research Everyday thinking is often characterized by Good academic research is characterized by Poor data Incomplete data Hasty thinking Sufficient data sources Appropriate data sources Accurately recorded Properly analyzed No hidden assumptions Conclusions well-founded Properly presented As judged by the users of the research
- 4. The computing discipline includes computer science, software engineering, information technology (IT), web development, computer games, computer animation and multimedia. We will cover the kinds of research questions addressed in computing the research approaches used in computing examples of previous research from computer literature Computing Discipline
- 5. Until recently, almost all computing research was concerned only with developing computer-based products (for example, data processing systems, websites, artificial intelligence robots, computer games and digital art etc.) and the methods we use to design and creation research, and to analyze and evaluate the work of other computing researchers. A Lack of Evidence There are plenty of computer science theories that have not been tested. For instance, functional programming, object-oriented programming and formal methods are all thought to improve programmer productivity, program quality or both. It is surprising that none of these obviously important claims have ever been tested systematically, even though they are all 30 years old and a lot of effort has gone into developing programming languages and formal techniques. Evidence-based Practice
- 6. The internet and world wide web are becoming increasingly important in our modern world offer exciting possibilities for both new research topics and new research approaches. We will cover some possible research topics about the internet or web how the internet can be used as a tool within a research approach (for example, internet-based research surveys, and internet ‘interviewing’) how internet-based research is different from other types of research examples of previous research studies that have investigated the internet or world wide web or used them to support the research process The Internet and Research
- 7. I Just Want to Develop a Computer Based System I Just want to develop a computer system and write a report about it, not collect and analyze data or make arguments. The response is that designing and creating any kind of computer based product is still a form of research, which requires finding or generating data, analyzing it and drawing conclusions. The research question is, ‘Is it possible to develop a computer based product to do X’? In order to define that question fully (for example, what is X? why is it important to have computer system to do X?) and then to answer it, you will have to: gather data about the computer based product required (for example, interviewing people, examining company documents, or studying the cultural or genre conventions for a particular kind of animation); generate your own data (for example, system models, storyboards, character sketches) to document how and why you designed and implemented the product; Test the computer based product and obtain user or viewer feedback, which will involve more data generation and analysis (for example, testing logs, user questionnaires, observation of audience reactions)
- 8. Rigour and Relevance in Research Rigour encompasses both systematic conduct and validity. Relevance is defined as ‘being pertinent, having direct bearing/performance’
- 9. The 6Ps of Research Purpose Products Process Participants Paradigm Presentation
- 10. Purpose, Product, Process Purpose: The reason for doing the research, the topic of interest, why it is important or useful to study this, the specific research question(s) asked and the objective set. Research without a purpose is unlikely to be good research. Product: The outcomes of research, especially your contribution to knowledge about your subject area. Your thesis, dissertation, conference paper or journal article is also a product of your research. For those research projects that involve design and creation, a new computer based product or new development method could also be a product of your research. Process: The sequence of activities undertaken in any research project. As explained already, the process should be carried out systematically if the research is to be accepted as rigorous.
- 11. Participants, Paradigm & Presentation Participants: These include those whom you directly involve in your research, for example by interviewing them or observing them, and also those who are indirectly involved, such as the editors to you submit a research project. You yourself as researcher are also a research participants. Paradigm: A pattern or model or shared way of thinking. Researchers sometime talk of the need for a ‘paradigm shift’ to mean that a new way of thinking is required. Presentation: The means by which the research is disseminated and explained to others. It is important that the presentation is carried out professionally – otherwise your audience might assume your whole research project was not undertaken in a professional manner.
- 12. Go forth and research…. … .but be careful out there.
