Example: a real quiz from this tool

Input: “Slide 2: Reinforcement increases behaviour; punishment decreases behaviour. Speaker notes: Negative reinforcement still makes a behaviour MORE likely, because something unpleasant is taken away. Slide 3: Positive punishment: speeding ticket. Slide 4: Speaker notes: Fixed-interval schedules produce a scallop pattern: little responding right after a reward, then a burst as the next one gets close.”

  1. How does negative reinforcement differ from punishment in operant conditioning? A. Negative reinforcement decreases behavior, while punishment increases it. · B. Negative reinforcement increases behavior by removing an unpleasant stimulus, while punishment decreases behavior. ✓ · C. Negative reinforcement adds a pleasant stimulus, while punishment removes a pleasant stimulus. · D. Negative reinforcement is always more effective than punishment.
    Why: Negative reinforcement increases behavior by removing something unpleasant, whereas punishment decreases behavior, as clarified in the source.
  2. In which scenario would a fixed-interval schedule of reinforcement most likely produce a scallop pattern of responding? A. A student receives praise after every correct answer. · B. A worker is paid every two weeks. ✓ · C. A child is rewarded for every third time they clean their room. · D. A player wins after an unpredictable number of spins on a slot machine.
    Why: A fixed-interval schedule, such as being paid every two weeks, leads to a scallop pattern where responses increase as the reward time approaches, as described in the source.
  3. If a student receives a speeding ticket for driving too fast, what type of operant conditioning is being applied? A. Positive reinforcement · B. Negative reinforcement · C. Positive punishment ✓ · D. Negative punishment
    Why: A speeding ticket serves as a positive punishment because it adds an unpleasant consequence to decrease the likelihood of speeding in the future, as outlined in the source.

Slides are sparse, so give the quiz more to work with

Lecture slides are written to be talked over. "Fixed ratio, variable ratio, fixed interval, variable interval" on its own gives an AI four terms and nothing to test about them, so a quiz made from bullet points alone tends to be a list of definition questions. The explanation that turns those terms into something examinable was said out loud in the lecture.

Look at the example: the question about the scallop pattern could only be written because the speaker notes explain it. The slide itself just lists the four schedules. Wherever your slides are thin, add context, either through speaker notes or by pasting a few lines from your own lecture notes into the text box next to the attached file.

PPTX or PDF: which to upload

Upload the PPTX when you have it. Text on the slides and the speaker notes are both extracted, and many lecturers put their real explanations in the notes. A PDF export usually contains only what is visible on the slides, unless it was exported as notes pages. Scanned or image-only PDFs are still readable, because pages with no text layer are passed through AI text recognition.

Charts, diagrams and images inside slides are not interpreted, only the text on and around them. If a key slide is a diagram with few labels, type a sentence describing what it shows. Files can be up to 8MB each and you can attach up to 5, so a long deck split into parts, or slides plus the handout, both work.

One lecture at a time

A single 30 to 50 slide lecture is roughly the right size for one quiz. Attaching a whole term of slides spreads the questions across dozens of topics and cuts off text beyond the length limit. Quiz each week's deck soon after the lecture, then combine the decks you struggled with into a review quiz before the exam.

Frequently asked questions

Does it read speaker notes in PowerPoint files?

Yes. When you upload a PPTX, the speaker notes are extracted together with the slide text, so explanations the lecturer wrote there can be turned into questions. A PDF export normally drops the notes, which is one reason to prefer the original PPTX.

What about Google Slides or Keynote?

Export the deck first. From Google Slides use File, Download, Microsoft PowerPoint (.pptx); from Keynote use File, Export To, PowerPoint. Both keep the speaker notes. Exporting to PDF also works, but usually only the visible slide text comes through.

My slides are mostly images and diagrams. Will it work?

Only partly. Text inside images and labels on diagrams can be read, but the meaning of a chart or a flow diagram is not interpreted. Add a short written description of the key diagrams in the text box and the quiz will cover them.

Are my uploaded slides stored?

Without an account, attached files are deleted after 24 hours. If you create a free account, the quiz is saved along with the files you attached, so you can retake it later without uploading the deck again.
