LEPTON - LEarning Physics ThrOugh Nature

LEPTON Policy Document (pdf)

LEPTON is a new central program suggested by NANI for each Anveshika to conduct. In this, Anveshika coordinator along with his/her team will conduct offline LEPTON sessions in various institutions (schools and colleges) of their regions. Student groups from class 9 and above in the school and B. Sc and M. Sc students in colleges, will be approached to participate in such sessions. Apart from the contents decided by the Anveshika, LEPTON sessions will include a video based MCQ quiz.

During the LEPTON program, the quiz will be conducted based on the videos shown on the screen and the students will mark their answers to the MCQs asked, on the question paper shared with them. There should be 9-10 videos and 15-20 questions. For each question, there will be a short video and the MCQ will be based on that video. There may be more than one question on the same video. The answer papers will be collected and evaluated by the resource persons just after the quiz. In parallel, discussion of the quiz should be done after collecting the papers. The LEPTON program can be conducted any number of times in nearby institutions. Anveshika can give certificates and prizes if they decide that way.

Anveshika coordinators can devise their own ways to conduct the program where they can evaluate and identify top performers. For each LEPTON Program conducted for school students up to 31st May 2024, the top 2% based on the quiz marks, can be given lateral entry in NAEST Prelims of 2024. For each LEPTON Program conducted for college students up to 31st May 2024, the top 4% based on the quiz marks, can be given lateral entry in NAEST Prelims of 2024. To avail this opportunity the following information must be shared with NANI on the designated websites.

  1. The video question paper to be used, must be shared with, and approved by NANI. This must be done at least 10 days before the session. Please see FAQ below on making question papers. Same question paper can be used for more than one LEPTON programs if there is no chance of 'leaking the questions.'
  2. A complete data of the participating students which includes their name, class, school, email-id and contact no. will be maintained for each such program. The institution in which the program is being held can help in this by assigning a LEPTON Faculty Coordinator (LFC). The coordinator will float a form (created centrally by NANI) to the students who will attend the program asking for the above-mentioned details. On the day of the program in that institution, attendance of the students can be taken based on the collected data. Provision of immediate filling of data for last-minute entries will be allowed.
  3. The result for each of the participating students together with the top 2% for school (or 4% for college) performers must be sent within 5 days of the quiz.
  4. To calculate the percentage, only the whole number contained in 2% will be counted. For example, 2% of 260 school students appearing in a session, 5 will get this benefit.

Proposed plan for transmitting information.

Excel files of the data created for each such program must be uploaded directly on the LEPTON website which will be created solely for this purpose. The website will have different buttons corresponding to each of the Anveshikas. Each Anveshika coordinator will have access to upload the details of their LEPTON programs only at their assigned place. If an Anveshika conducts 10 such programs at various dates, the Anveshika coordinator will upload 10 excel files corresponding to each program under the Anveshika. The file should be uploaded within 5 days of the conduct of the program. Also, the paper used for that program must be uploaded on the LEPTON website.

The whole purpose of LEPTON is to reach the greatest number of students and give them the feel of how beautiful is our world and its description, physics. Each Anveshika will develop contacts with school/ colleges and that will help in the campaigning for upcoming NAEST. Many of the LEPTON Faculty coordinators can be persuaded to work as NAEST faculty coordinators. LEPTON should be viewed as a central program of NANI and each Anveshika should do such programs.

Benefits to serve NANI vision from LEPTON

This is an opportunity for

  1. building rapport with institutions at a personal level and not just forwarding NAEST Posters.
  2. LEPTON faculty coordinator (LFC) can be the workhorse for all Anveshika programs.
  3. promoting NAEST throughout the year.
