Question templates

Ten questions that work in any lecture — one import file per field with a topic and a ready-made playlist, German and English in a single file. Open it in LehrPuls under Playlists → Import (.lpx, .json); afterwards you can edit the questions freely and copy them into your own playlists.

Tools for your own analyses

With the read-only interface, other programs fetch the results directly from LehrPuls — read-only, with a time-limited key, and anonymized by default. Turn it on under Settings → Read-only interface (manual section 10.9).

Analysis in the browser

A page to save and open: enter the key, and it shows the answers of the last session per question — distribution, share correct, open answers. No other program needed.

Power BI and Excel

A ready-made Power Query for the figures per question, per topic, and the participants’ scores. A report template with charts will follow.

lehrpuls-kennzahlen.pq

R

A script with the same queries as data frames (httr, jsonlite) — metrics per question, per topic and the participants' balance, ready for further analysis.

For researchers

The Research Kit describes the data model, the fixed column contract of the raw data export, the endpoints of the read-only API, and the formulas of all metrics — with notes on consent, anonymization, and deletion deadlines and a list of open research questions. It comes with a synthetic sample data set and analysis scripts in R and Python that run without LehrPuls.

Sample data set

Synthetic, in the format of the raw data export: 2 courses, 3 semesters, 533 participants, 18,870 answers, 16 questions with a peer instruction round. Includes the generator (fixed seed).

Analysis scripts

Difficulty, discrimination, peer instruction gain, longitudinal view, and response times — from the sample data set, your own export, or directly from the read-only API. Script output labels are German.

For IT

The Windows version can be installed silently: for all users with /S /AllUsers (administrator rights), for the signed-in user only with /S /CurrentUser, each after the name of the installer file. Each person enters their own license; data is stored per user.

The data folder and relay address can be preset with environment variables (LEHRPULS_DATA_DIR, LEHRPULS_RELAY_URL, manual section 11.4). Checksums of the installers are on the start page next to the download.
