[app] Multiplication Trainer #app #android #tugraz #trainer

We are happy to announce another learning app – the multiplication trainer for android. It is part of our math-trainer applications, which you can find here.

An educative game where you train your multiplication skills.
You can challenge your skills offline, and to play online, you need to create an account on „Learning Apps TUGraz“ ( https://schule.learninglab.tugraz.at/ ).
With each correct or incorrect answer, you will be prompted with feedback from the server that generated the assignment.
It will either congratulate you or tell you the right answer if you failed to give one.
The server keeps track of your personal statistics and gives you challenges appropriate to the skill level that you previously demonstrated.
The better you are, the harder is the challenge.

[presentation] Bayesian Modelling of Student Misconceptions in the one-digit Multiplication with Probabilistic Programming #lak16 #research

Our presentation at this year conference on Learning Analytics (LAK 16) was about „Bayesian Modelling of Student Misconceptions in the one-digit Multiplication with Probabilistic Programming„. Here you can find the slides:

[publication] Determining the Causing Factors of Errors for Multiplication Problems

Our chapter about „Determining the Causing Factors of Errors for Multiplication Problems“ as part of the book „Immersive Education“ got published.
Abstract:

Literature in the area of psychology and education provides domain knowledge to learning applications. This work detects the difficulty levels within a set of multiplication problems and analyses the dataset on different error types as described and determined in several pedagogical surveys and investigations. Our research sheds light to the impact of each error type in simple multiplication problems and the course of error types in problem-size.

[publication] TEACHERS LITTLE HELPER: MULTI-MATH-COACH

Our publication on „TEACHERS LITTLE HELPER: MULTI-MATH-COACH“ is now online available in the Journal on WWW/Internet. The articel is free for download right here [download link].
Abstract:

Individual learning is out of sync with the elements of a curricula and the daily program of a teacher. At a time when multidigit multiplication methods are taught, many children are not perfectly performing the basic multiplication table. Teachers organize settings for learning and they usually have no time to give an individual feedback to every single student. Furthermore they have no physiological capacity to produce statistics and to investigate the probable causes of errors. Our goal is to give teachers a tool to help them to review and train some typical requirements for written multiplying. We use the ubiquity of the Internet and provide on different devices free applications with written multiplication problems. All data are collected centrally and are used to determine typical errors. These data could also be used to answer further new questions and test new hypothesis. This is one aspect of Learning Analytics. The given tasks are automatically adapted to the skill level of a student. Teachers can see every detail of the solution process of every task. But really useful is that teachers can see the typical problems of each student as well as of the whole class every time at a glance. They need just a connection to the database with a web browser – anywhere, anytime.
Finally the first evaluation of the system pointed out some remarkable results. Children are learning with the system in the intended way according to the shown learning curves.

[iPhone App] 1×1 Trainer

Eine weitere App erstellt im Rahmen einer Masterprojektarbeit an der TU Graz ist ab sofort im App-Store verfügbar. Es ist ein Einmal-Eins-Trainer, der in Abhängigkeit vom Ergebnis eine Lernrate berechnet und daraus die nächste Aufgabe ableitet. Dies bedeutet, dass das Programm mit dem Können des Kindes mitlernt und Aufgaben ganz gezielt gestellt werden. Wir haben dazu bereits auch eine Webversion und eine Android App ist ebenfalls in Vorbereitung. Inzwischen viel Spaß einmal mit der iPhone-App:

The 1×1 Trainer is a learning game for children who are trying to master the tables up to ten.
There are two ways to play:

  • The Trainer, where you need to create an account to play and all your learning progress will be saved online for you to keep track.
  • The Speedgame, where you just play a simple 1×1-Game with a time-limit depending on the chosen difficulty and try to answer as many of the 20 presented examples as possible. The better you perform, the higher your Score will be.

This App provides a nice and fun learning experience, motivating the children to improve their abilities and keeping frustration to a minimum!
Have Fun!
