In this study, an innovative tool for enabling contextual teaching based on visual inputs, named Visual Stimuli-based Teaching Aid (VISTA), was developed. This system establishes the meaning and significance of concepts that are taught in the classroom within different environmental contexts. The idea of contextual teaching has been deliberated for more than a decade now. Nevertheless, using this in a classroom with limited time and resources has several challenges. VISTA leverages the ubiquitous mobile devices to boost conventional teaching methods with contextual teaching–learning. With VISTA, contextual teaching does not require any specialized device, expensive sensors, or simulated environment. To assess the applicability of VISTA in computer science education, we gathered the responses and experiences from 42 computer science teachers teaching in various universities of India. The responses garnered indicate that contextualization through VISTA is relevant as well as interesting. In total, 86.31% of the teachers found the contextual information provided by VISTA to be significantly related to both the captured images and the concepts presented in the class. These results encourage the use of VISTA as a pedagogical tool for contextual teaching.

VISTA：增强情境教学的教具

在这项研究中，开发了一种基于视觉输入的情境教学的创新工具，名为基于视觉刺激的教学辅助 (VISTA)。该系统确立了在不同环境背景下在课堂上教授的概念的意义和重要性。情境教学的想法已经考虑了十多年。然而，在时间和资源有限的教室中使用它有几个挑战。VISTA 利用无处不在的移动设备，通过情境教学——学习来推动传统教学方法的发展。借助 VISTA，情境教学不需要任何专用设备、昂贵的传感器或模拟环境。评估 VISTA 在计算机科学教育中的适用性，我们收集了在印度各大学任教的 42 位计算机科学教师的反馈和经验。获得的回应表明，通过 VISTA 进行情境化既相关又有趣。总共有 86.31% 的教师发现 VISTA 提供的上下文信息与捕获的图像和课堂中呈现的概念都显着相关。这些结果鼓励使用 VISTA 作为情境教学的教学工具。
