SIMPLEX Education, 2021–2024

What webuilt.

We built learning tools in Aachen: to find gaps in maths, bring students together, and give teachers more time to teach.

SIMPLEX closed in 2024. These working demos preserve a little of what we made.

Skill → the foundations it needs

Root rules and rational numbers are its foundations. Follow either branch to see what comes first.

Finding the gap behind the answer.

Our LSA connected exercises to a map of mathematical skills. When something was difficult, it could look at the foundations underneath. Try four original questions and follow the route.

Irrationale Zahlen

The learning tree, underneath.

Four connected skills from the original curriculum. The lines already exist; your answers add evidence.

How we built the map
  1. Define a skill in the curriculum.
  2. Link the skills it relies on. Foundation references could cross curriculum branches.
  3. Attach exercises and their weights in LSA Studio.
  4. Use assessment evidence to decide which linked skills to explore.

□ Foundation reference Answer correct Revisit / unsure Not tested

We begin with irrational numbers, then try a gap fill with answer tiles. After that, your answers guide us through the foundations.

    Selected exercises and prerequisite links from the 30 April 2024 backup. Original German prompts, including complete gap-fill exercises. This short route illustrates the idea, using a simplified evidence rule.

    LSA Studio

    Where the questions took shape.

    Our internal editor brought the exercise, its subquestions, and its competencies together. Try the original root exercise as a gap-fill task, then explore multiple choice, free text, or ordering and open the student preview.

    Put the answer in square brackets to create a gap: [5]. Separate accepted alternatives with |, for example [2,31|+2,31].

    About these answer formats

    The gap-fill task uses all four lines of the original exercise. Switching task types lets you explore the other answer formats. Your edits stay in this demo.

    Before & after assessment

    What changed during a course.

    Students reflected on how they learned before and after a course. Change the self-ratings to compare the two shapes.

    Your perspective, before and after.

    Students rated their own confidence before and after each course.

    Coach recruiting

    A queue, a call, a new coach.

    Finding a gap was only the beginning. Teaching needed people, and people needed a plan.

    Hundreds of coaches, a small recruiting team. A shared queue kept interviews moving. Take the next candidate, try a sample interview, and decide what happens next.

    Recruiter cockpitSample interviews · Fictional candidates

    Ready for the next call?

    Take a candidate from the queue to open their sample interview.

    The queue is ready. Try the first interview.

    The original cockpit combined a shared candidate queue, meeting creation, interview scoring, and four outcomes. This example uses fictional candidates; no calls, bookings, or messages are sent.

    Holiday course registration

    From “I’m in” to a plan.

    Coaches told us their available days, preferred year groups, and whether they wanted to lead a team. Try their form and watch the planning desk receive the answers.

    Then assign coaches to schools

    Based on the holiday-course registration fields: available dates, preferred school levels, and willingness to lead. The sample form and planning view use invented responses.

    Coach availability

    Who could teach, and when.

    Before a lesson could be planned, we needed to know who was available. Pick a day, change a coach’s response, and fill a sample lesson slot.

    Course planningExample week · Fictional coaches

    Click a response to cycle through available, unavailable, and undecided.

    ✓ Available× Unavailable? Undecided

    The original planner separated known and unknown availability and used three response states. This example keeps those choices, with fictional names and times.

    Right coach.
    Right school. Fewer miles.

    Hundreds of courses, a lot of moving parts. Our planner found coach assignments that worked for the people making the trip.

    Change the priority, then run the planner.

    Plan details and all assignments

    Taking the first available coach works. But there is a better way to connect the dots.

      A longer trip. A shorter team total.

      Giving one coach their closest school can make another coach travel farther. Compare the pair; the other four assignments stay fixed.

      Two alternatives to the first-available plan. Choose one to update the map and total.

      A small, exhaustive assignment search inspired by the original planner. Travel times and schools are illustrative.

      Learning group clustering

      Learning together, with the right group.

      The original workspace kept unassigned students beside their groups. Try assigning people yourself, or let the solver bring similar learning needs together.

      A small company.
      A lasting collection.

      SIMPLEX began in Aachen in 2021 with maths tutoring. Over time, we built our own software around the students, families, coaches, and schools we worked with.

      The company is no longer operating. This domain now holds a personal archive of the work: the learning analysis, the authoring tools, and the less visible systems that helped everything run.

      The examples above are small, working excerpts, adapted for this archive. The LSA uses selected original exercises and skill links. The people, bookings, and schedules in the other demos are fictional.
