The brainchild of Kanker Collector Shammi Abidi, the video lecture database titled 'Setu' (bridge) is currently being used for running a remedial course in mathematics for class IX students and for weekly training of primary and middle school maths teachers who do not have the subject background.
The district falls in the under-developed Bastar region where government schools suffer tremendously from lack of teachers. To add to the woes, skilled teachers from outside are reluctant to come to the conflict-ridden zone and the locals lack the training.
"The remedial course for maths is being run in more than 100 high schools where a significant improvement has been observed in the learning level of the students," she claimed.
"Such an initiative in a systematic and effective manner is being taken arguably for the first time in Hindi medium government schools of the country," the IAS officer told PTI.

The course was started in the current academic session and shall be completed by the middle of this month, she said.
The Bastar region faces a problem of lack of teachers particularly for mathematics and science.
However, after launching of 'Vidya Mitan' project by the government, the problem was solved to a great extent but still interior pockets are devoid of teachers, she said.
The video lectures concept was introduced to address the problem so that students from these areas could get some kind of guidance, she said.
On how the method conceptualised, Abidi said during a review exercise in December last year, theycame to know that the students of class IX and X are unable to carry out basic mathematical calculations.
Education) report 2015-16, there are 188 upper primary schools in Kanker where mathematics is being taught by teachers who graduated in arts subjects.
"This has a direct effect on the learning levels of students," the Collector said.
It was realised that to improve the learning, video lectures could be of great use.
A lecture database which covers mathematical concepts in Hindi language was not available in the market. Hence, it was decided to develop these videos indigenously, she said.
The database consists of 63 videos and each spanning 30 minutes. All are scrutinised by maths teachers of senior classes in schools.
Besides, the database will help students solve numerical questions which are asked in subjects like economics, physics, chemistry, biology and geography.
The schools are supposed to screen Setu videos with the help of TV/projector and hard disk, according to a time table set on a daily basis for class IX students.
Active involvement of the teacher while screening the video lectures is a must. At the end of every lecture there is a set of questions for self assessment, Abidi said.
To assess the impact of video lectures, a sampling of Girrhola high school and Chawadi high school of Charama block was done. The data shows that there has been a significant improvement is learning levels via Setu, she said.
These lectures have been uploaded on YouTube so as to benefit students of the Hindi belt. The videos can be accessed by searching 'Setu Chhattisgarh' on YouTube, she said.
A similar projectnamed 'Pragya' is also being run by Kanker district administration to tackle the problem of shortage of science, mathematics and English teachers in high/higher secondary schools of the district.
Setu and Pragya differ in the technology used, the target segment and their purposes, Abidi added.
