The precursor of any problem-solving strategy is the visualization of the problem at hand. When dealing with problems pertaining to STEM (science, technology, engineering, and mathematics) areas, visualization plays a very significant role in addressing the same. Several initiatives are being taken to improve the visualization skills of the students and spatial reasoning techniques have proved to be one of the most widely accepted tools for addressing the problems in the STEM field. In this paper, we specifically address the use of spatial reasoning to solve problems in the form of puzzles taken from electrical engineering and analyze the fruitfulness of employing such a strategy. The puzzles are hosted in an online interactive framework called UNTANGLED and classified into different categories on the basis of the nature of the puzzles and their difficulties. The results indicate that spatial reasoning technique indeed helped the players to successfully complete the puzzles. The interpretation of the data led to the conclusion that spatial reasoning techniques are imperative when it comes to discerning and resolving a problem, especially in the STEM domain.

Serious games have grown as one of the alternative means to assist people with cognitive and learning disabilities. They have been found to have a positive influence on these people and to help them improve their social skills. They offer them a stress-free environment that assists them in working on their skills at their own pace. Studies have shown that no one game is fit for all kinds of disabilities. Instead, these games must be tailored according to the specific needs of the disability. This paper discusses some of the prevalent serious games and the frameworks that can be used while designing them. Serious games need to be made broadly accessible for people in developing countries to increase their efficacy. Using serious games has helped the disabled to overcome their anxiety, as well as help them in coping with their disability, and its effectiveness to do so is also proven in some studies.
