Accessibility for educational games is a work in progress across the industry. We continually seek solutions to make our products fully accessible and we strive to adhere to established standards for accessibility and usability on each new project. Some of our older products may not be accessible in all areas, and have not been optimized for current accessibility recommendations. Here, we offer the content and approach of this game, so that learners are better able to find alternative content and ways of learning.
The Sorption interactive is intended to explain the specific process of completing a soil adsorption and absorption lab. This module is very versatile in function which can be used as a study tool to expose students to the basics of laboratory soil science or as a teaching aid. While using the module, students utilize a variety of laboratory tools while learning how each one plays a role in the sorption experiment. The module illustrates actual laboratory experiments and procedures, with attention to the planning and organization required to obtain valid results in the lab.
Users explore the concept of adsorption and its importance in the soil sciences with an interface utilizing a mouse or trackpad. This module does require some precision, so it may not be suitable for users with fine motor issues or eye hand coordination difficulties. The module requires mostly mouse or trackpad clicking and very few instances of dragging. For example, the user drags a bottle of solution to a scale to measure the weight of the solution.
Regarding student accessibility, students who are hearing impaired can complete all the experiments without sound, as the module’s text box (closed caption) feature accurately identifies the speakers in each experiment. Users who need access to the module but who may not be able to complete the clicking and dragging tasks can access the full module by clicking several times on the New Mexico State University logo on the first page. This game is only playable on platforms that support Adobe Flash, which may no longer be supported by browsers beginning in 2020. It is not supported by mobile devices. Sorption is only accessible in English.
