This document discusses computer-based instruction (CBI), including its categories, characteristics, applications in education, advantages, limitations, and research findings. CBI is defined as using computers to deliver instruction and includes drill-and-practice, tutorials, simulations, instructional games, and problem-solving programs. Research shows CBI can improve performance, reduce time needed, and positively impact student attitudes compared to traditional instruction. Effective integration and evaluation of CBI software are also discussed.

Assessment involves the use of empirical data of student learning to refine programs and improve student learning. Assessment is used in many ways in education. The good deal of attention is given to the use in helping and learning. Assessment consist of the diverse learners needs the learner’s assessment assess the certain level of individual that include concepts of exemptions, concession, adaptation and accommodation. All are perfectly helpful for the assessment of diverse learners.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
