Now in testing

Two tools, ready to try.

CS42 is where we design and test new tools. Two are being tested now: live quizzes for a whole class, and well log analysis from the first plot to the final report.

Experiment · The Platform · Ready for testing New Live quizzes inside PowerPoint

Quiz the whole class, live.

The Platform runs live classroom quizzes on top of a real curriculum. Every question is tied to its grade, subject, chapter, section and learning outcome, so a quick game also shows what the class has actually learned.

Ready for testing. Anyone with a UAE Ministry of Education email address (moe.gov.ae or moe.sch.ae) can create a teacher account and start hosting games.

Not on the MOE network? Email us to request access.

  1. Host

    Start a game in under a minute.

    Pick questions by chapter, section or learning outcome, or let it choose a balanced set. The big screen shows a PIN and a QR code, and names pop up as the class joins.

    The lobby on the big screen: the game PIN, a QR code to join, and six students who have joined

  2. Play

    Everyone answers on their own phone.

    Students scan the code, make a name like Blue Falcon 7 and answer against the clock. Faster right answers score more, a streak adds a bonus, and nobody needs an account.

  3. Learn

    See what the class actually knows.

    Every answer is revealed with a short explanation. After the game, a report breaks the results down by student, question and learning outcome, and Insights shows where students struggle across every game.

    The game report: class accuracy, scores and a tick or cross for every student on every question

New · PowerPoint add-in

Quizzes and polls, right on your slides.

Add it to PowerPoint once, and any slide of your lesson becomes a live quiz or a quick poll. Students answer on their phones while you run the game from the slideshow, without switching windows.

  • A saved quiz on any slide, or a new one built without leaving PowerPoint
  • Quick polls: choices, a rating from 1 to 5, or a word cloud
  • One PIN for the whole lesson, with scores that add up from slide to slide
  • Your clicker moves the game on, and the results go back into the slides

For PowerPoint on Windows, Mac and the web. Sign in on the slide with your teacher account.

  • Live, self-paced or homework

    Run it on the projector, open a quiz for a set time, or set it as homework with a due date and no timer.

  • Every class, its own page

    Quizzes, results, student IDs and statistics for each class, and a quiz copied to another class in one step.

  • A bank with no gaps

    A coverage table shows which outcomes and difficulty levels still need questions.

  • Teachers add questions

    Suggestions go to reviewers, and approved ones carry the name of the teacher who wrote them.

  • Leaderboards that mean something

    Best results for every section and chapter, this week, this month and all time.

  • Excel in and out

    Import a whole bank from a spreadsheet, with every row checked before anything is saved.

Students never need an account: they join with a PIN and stay anonymous. Open The Platform · How to use it

Experiment · Stratum · In testing

Well logs, read properly.

Stratum is a well log analysis app for oil and gas data. Load LAS or DLIS files, plot them, clean them up, run the petrophysics and write the report, all in one place.

  • Open hole and cased hole in one project
  • For Windows and macOS, or hosted for a team
  • Tested on 118 public wells from the North Sea

Password protected while it is being tested. Request access and we will reply by email.

Stratum's log plot of a North Sea well: gamma ray, caliper, resistivity, density and neutron, sonic, lithology and shale volume tracks

Open hole: gamma ray to net pay.

Shale volume, porosity, water saturation, permeability and net pay, with crossplots and histograms to set every parameter.

Cased hole: cement, sigma and flow.

Cement bond with the VDL image beside it, pulsed neutron saturation over time, and production logging.
