Every practice question you solve on an app, and every worked solution and explainer video, was written by someone who knows the subject. If you like science but are unsure about research or classroom teaching, edtech content development is a career path worth a look, and you can practise its skills before you apply.
What does an edtech content developer actually do?
The work usually splits into a few kinds of task, and one person may do several:
Question writing: practice and test questions, mapped to a syllabus and a difficulty level.
Solution writing: step-by-step explanations that show why each step follows, not just the answer.
Concept explanations and scripts: short lessons, notes and the scripts behind videos.
Video: recording explainers on a board, tablet or lightboard, or working with an editor who does.
Review: checking someone else's questions for errors, ambiguity and syllabus fit.
This is not only private companies. DIKSHA, the national school-education platform and an NCERT initiative under the Ministry of Education, was launched in 2017. Its page says a rich repository of resources was contributed by schools, teachers, content partners and NGOs under VidyaDaan.
What skills do science graduates need for edtech content?
Subject depth comes first, because a wrong answer key reaches every student who attempts that question. Beyond that, three skills matter, and each has research behind it.
Writing questions with useful wrong options. A good multiple-choice question has wrong options (distractors) built from real student mistakes, so a wrong pick tells you something. A 2017 review of distractor research in Review of Educational Research by Gierl and colleagues notes that creating distractors has received much less attention than other parts of multiple-choice testing. More options are not always better: a meta-analysis of 80 years of research by Michael Rodriguez concluded that three options are optimal for multiple-choice items. Our post on writing MCQ distractors that reveal misconceptions goes further.
Writing explanations that do not overload. Richard Mayer's 2017 review of 12 multimedia learning principles works as a practical style guide. Words with graphics beat words alone (median effect size d = 1.67). Cutting extra material, the coherence principle, had an effect size of d = 0.70, and breaking a lesson into learner-paced segments also had d = 0.70.
Making short, personal videos. Philip Guo, Juho Kim and Rob Rubin analysed 6.9 million video-watching sessions across four edX courses, measuring engagement by how long students watched. Shorter videos were much more engaging, and they recommend splitting videos into chunks under 6 minutes. Khan-style tablet drawing was more engaging than slides, instructors who spoke fairly fast and with high enthusiasm were more engaging, and videos with a more personal feel could be more engaging than high-fidelity studio recordings.
If explaining in writing appeals most, see our guide to a technical writing career too. If you would rather explain face to face, compare it with the science teacher route through B.Ed and NET.
What does a good content sample look like?
Here is a Class 11 physics question with three options, each wrong one tied to a known mistake.
Question: A ball is thrown straight up. At its highest point, what is its acceleration?
Zero, because the ball has stopped for an instant
9.8 m/s² downward
9.8 m/s² upward, because it was moving up
Answer: 2. Gravity acts the whole time the ball is in the air, so the acceleration is g downward at every point, including the top.
Why each wrong option exists: option 1 catches students who mix up velocity (zero at the top) with acceleration. Option 3 catches students who think acceleration points the way the object moves.
When you study model solutions, look at how the steps in the Fermi Problem Library explain the reasoning rather than printing an answer, and ask whether yours does the same.
How do you start an edtech content career?
Build a small portfolio in four weeks.
Week 1: pick one chapter you know well. Write 10 three-option questions. For each wrong option, write the mistake it is meant to catch.
Week 2: write full solutions. Give the set to a younger student, note where they get stuck, and rewrite those parts.
Week 3: record one explainer on your phone, writing by hand on paper or a tablet, and keep it under six minutes, as the edX video study recommends. Watch it back and cut anything that does not help the main idea.
Week 4: put your best three questions, solutions and the video in one shared folder. Apply for content, subject-matter-expert and solution-writer roles, and ask for a sample task.
Before you send anything, run this check:
Is the answer key correct, and have you solved it twice?
Does each question test one idea?
Does every solution step say why, not only what?
Are units and signs consistent?
When planning a chapter, the Fermi Concept Library gives every concept in physics, chemistry, biology, mathematics and computing its own lesson and its place in the map, which can help you order your questions from simple to hard.
Start with one chapter this week.
