This application is a research questionnaire to measure the effectiveness of vocabulary learning methods based on the Involvement Load Hypothesis (ILH) principles.
It allows users to take a research questionnaire easily and researchers to effortlessly create ILH questionnaires, distribute them globally, and analyze results through interactive data visualizations.
The ILH theory posits vocabulary learning is more effective when it incorporates a higher involvement load - i.e. need, search, and evaluation.
This app measures ILH scores through 3 categories of questionnaire questions:
- Need - the necessity of learning vocabulary
- Search - the effort to understand vocabulary meaning
- Evaluation - assessing vocab knowledge Based on user responses, it calculates category scores and total ILH scores. The results are displayed in a bar chart showing the breakdown and total score.
It enables researchers to quickly evaluate vocab learning methods and iterate on questionnaires.
This is a Next.js project bootstrapped with create-next-app.
