- 5. – Information and communication technologie is an umbrella term that includes all technologies for the manipulation and communication of information. – ICT considers all the uses of digital technology that already exists to help individuals, business and organization. – Information and Communication Technology (ICT) has greatly changed the teaching-learning process both at school and higher education level. – ICT has not only changed the instructional system but the examination and evaluation system is also being influenced to a great extent. – In the recent years several innovative initiatives have taken place in the field of examination and evaluation. – Online assessment is now very common all over the world. – Online examination make the assessments and evaluation system learner centric as it can be conducted when the candidate is ready, rather than at the convenience of the system.
- 6. ASSESSMENT – It is the process of identifying, gathering and interpreting information about students' learning. – It involves using wide variety of methods and tools to evaluate, measure, and document the student learning. – It basically helps one to improve learning and also set direction for ongoing teaching and learning process.
- 7. ICT Based Assessment – Use of ICT in assessment involves the use of digital devices to assist in the construction, delivery, storage or reporting of student assessment tasks, responses, grades or feedback. – Teachers can use computers to construct their assessment tasks, to deliver these tasks to relevant students and to record and provide feedback and grades to these students – It can be used to test many different capabilities and skills that are developed by students. – In many disciplines laboratory equipment can be manipulated remotely and students can undertake real time physical performances that are able to be recorded and used for assessment purposes. – Technology-enhanced learning environments, tools and systems recreate learning situations which require complex thinking, problem-solving and collaboration strategies and thus allow for the development of generic skills. – These environments allow learners and teachers to assess performance, understand mistakes and learn from them. – We are quickly approaching the stage where our imaginations will be the limiting factor in designing e- assessment tasks.
- 8. Computer Assissted Assessment – Computer-assisted assessment refers to the use of computers to assess students learning and performance. – It is a term that covers all forms of assessments, delivered with the help of computers. – It may be either online or offline, – some are marked with the aid of computers using Optical Mark Reading (OMR). – it helps students to discover whether they have learned what the educator intended and provide timely feedback. – It can be summative, with limited feedback typically being given at the end of a course and serving to grade and categorize the student's work. I – It can also be diagnostic, e.g. by testing for pre-knowledge.
- 9. Advantages – Computer assisted testing is more likely to be objective testing; testing that can be marked objectively and thus offers high reliability – The benefit is that the tests can be marked quickly and easily, and adapted to meet a wide range of learning outcomes.
- 10. Disadvantages – It is usually associated with testing knowledge and skills rather than conceptual understanding, because of the frequent use of multiple choice questions (MCQ) formatting – MCQ is believed to test at a lower level of understanding when related to Bloom's Taxonomy – Construction of good objective tests requires skill and practice and so is initially time consuming; – Hardware and software must be carefully monitored to avoid failure during examinations; – Security issues can be a problem in web-based CAA – Students require adequate IT skills and experience of the assessment type.
- 11. Computer Adaptive Test – One of the recent advancements in assessment – It add a great deal of efficiency to the testing process. – Depending on the student's responses, the software will automatically adjust the level of difficulty of the questions it poses – after a number of correct answers, it will move on to harder items – If there is too many incorrect responses, it will move back to easier ones – it include items from previous test content – allows measurement of a very wide distribution of knowledge and skills from below grade level to far above it – It might exist in any given class or testing group.
- 12. CAT Components – Calibrated item pool – Starting point or entry level – Item selection algorithm – Scoring procedure – Termination criterion
- 13. – Calibrated item pool – A pool of items must be available for the CAT to choose from – Starting point – In CAT, items are selected based on the examinee's performance up to a given point in the test. – Item selection algorithm – CAT has an estimate of examinee ability, it is able to select an item that is most appropriate for that estimate – Scoring procedure – After an item is administered, the CAT updates its estimate of the examinee's ability level – Termination criterion – The CAT algorithm is designed to repeatedly administer items and update the estimate of examinee ability
- 14. Advantages – It can provide uniformly precise scores for most test-takers. – It can typically be shortened by 50% and still maintain a higher level of precision than a fixed version. – Test-takers do not waste their time attempting items that are too hard or trivially easy. – Like any computer-based test, adaptive tests may show results immediately after testing.
- 15. Disadvantages – The first issue encountered in CAT is the calibration of the item pool. – Although adaptive tests have exposure control algorithms to prevent overuse of a few items, the exposure conditioned upon ability is often not controlled. – In a CAT with a time limit it is impossible for the examinee to accurately budget the time one can spend on each test item and to determine if he/she is on pace to complete a timed test section.
