学生在K-12中以母语学习，然后继续以英语进行本科教育，很难获得编程知识。旨在提高英语水平的解决方案需要时间，而那些在课堂上继续使用母语的解决方案限制了学生在全球市场上竞争的能力。另一个解决办法是使用基于视频的教学材料，使学生能够自定学习进度。在本文中，我们提出了一个比较研究的课堂教学与自定进度的屏幕播放的母语学习者的编程概念的收购。我们举办了四个介绍性编程研讨会，每个为期六天。两个讲习班以教室为基础，一个以印地语（母语）为教学媒介，另一个以英语为教学媒介。另外两个讲习班是以屏幕播放为基础的，一个是印地语，一个是英语。我们使用后测试来测量各组之间的差异，包括不同的内容类型，如事实，概念和过程。我们发现，当教学语言与K-12教学语言不同时，会对学习产生不利影响。然而，当使用自定进度的屏幕播放而不是教室环境时，表现在统计上有显着的改善。我们的工作为母语学习者选择教学语言和环境提供了信息。
Students, who study in their native language in K-12 and go on to do their undergraduate education in English, have difficulty in acquiring programming knowledge. Solutions targeted towards improving their English proficiency take time, while those that continue with native language in the classroom limit the students' ability to compete in a global market. Another solution could be the use of video-based instructional material to empower a student for self-paced learning. In this paper, we present a comparative study of classroom instruction versus self-paced screencasts for native language learners' acquisition of programming concepts. We conducted four introductory programming workshops, each of six days duration. Two workshops were classroom based, one having Hindi (native language) as the medium of instruction and other in English. Two other workshops were screencast based, again one in Hindi and one in English. We measured differences between the groups using a post-test, across different content types such as fact, concepts and process. We found that when medium of instruction is different from language of K-12 instruction, there is an adverse impact on learning. However, when self-paced screencast is used instead of classroom environment, there is a statistically significant improvement in performance. Our work informs the choice of MoI and choice of environment for native language learners.
