    2. Experiences with developing an adaptive or

    intelligent program

    3. Surprises & future Contact for use thisapplications

    Or: this is a story, how we began to think about a

    teaching problem, how we tried to solve it

    with a small application and how this leaded

    us to Learning Analytics & Educational DataMining

    Task

    Application to test the skills at the multiplication table.

    Special: Algorithm for a somewhere intelligent procedure. Situation:

    Pupil is introduced to a teacher. He/She tries to gain an overview of the

    tasks the students can do reliable well in an optimal way .

    Basics

    learning math starts before the school begins cultural differences, some obviously based on language

    implications

    linguistic competence is needed mathematic is the first non-native language

    many children do not really understand reasons for crucial

    aspects of the procedure

    the most common and traditional way to learn the

    multiplication table is drill and practice

    How to According to current neurological oriented

    research results, but also based on a veryold educational tradition, teaching should

    use tactile, optical and acoustic processing

    methods in every single case intensively

    when one observes deviations from the

    mainstream. Learning / teaching multiplication tables

    should not be reduced on a machine

    Program / Checklist

    The system should estimate the competence grade of thelearner

    The system should provide appropriate tasks according to

    the competence grade of the learner.

    Nevertheless the tasks should tend to be challenging.

    The system should ensure that already well-done exercises

    are repeated and practiced. After succeeding a problem the

    probability for a repeated display decreases in two levels

    (similar to a Leitner System )

    7/33

    Checklist cont.

    In general the system should be motivating and show thatlearning can be fun.

    The system should record and safe fine-grained data of all

    done exercises, test results and the current competence

    grade of the learner in order to prepare the next sessions in

    an adequate way.

    It should relieve the teacher from this unsolvable task as an

    information processing tool

    Checklist - Addon

    during this spring we defined another goal:Today we are able to present a database for organizing

    schools, classes and individuals with an interface for the

    conventional desktop browsers and also for Android and

    Apple mobile devices.

    The web-application ist written in php/mysql

    the apps in objectiveC (iPhone) &

    JAVA (Android).

    Measurement

    the goal is to generate a complete table to inform learnersas well as teachers about their competence in every single

    task, in every single multiplication fact

    (no probabilistic)

    Teachers can talk about quantity:

    I have 4 pupils who . And 6 who .

    (Will teacher recognize.?)

    Algorithm

    The presentation of the tasks is not only

    randomly generated..

    At the very first contact a moderate

    problem is presented. According to the

    results more or less difficult tasks arefollowing..

    The competence level of the test subject

    is then estimated and after every task

    recalculated. This determines the

    difficulty of the next tasks.

  • 8/2/2019 120430-lak12

    11/33

    Competence1. estimate the competence level:

    2. After every new solved or unsolved problem we choose

    a smooth way for adopting this first estimation of

    competence to the experience during the sessions

    12/33

    Difficulty

    Without any empirical data we decided to use the rankingfor the tables as follows Youll find this hierarchy in mostdidactical concepts:

    easy 1, 2, 4, 3, 5, 8, 6, 7, 9 difficult

    we transformed these ranking in difficulty levels between1 and 0.

    We discussed to integrate a statistical founded ranking, butat this point we fear, the teachers would be somewhereconfused about the results. Ill speak about this problem

    later.

    Stored Data

    The answers of the learners are marked with 0,1 or 2:1 shows that the user knew the correct answer once

    2 indicates that the student had two consecutive correct

    answers (this means a question is well known)0 indicates, the last answer was incorrect (or this item

    was presented never before)

    Additional we store: used time, result, task no., everpresented

  • 8/2/2019 120430-lak12

    14/33

    Selecting the next ItemWe use a random number between 0 and 1 ot decide, which

    category is activited to generate the next multiplicationproblem: Therefore three cases are defined:

    Case 1: If the random number is 0= 0.15 than a

    known question marked with 1 is chosen.

    Case 3: The random number is x > 0.15 than an

    unknown question out of the extended and actual learningarea is chosen.

  • 8/2/2019 120430-lak12

    15/33

    Extended Area

    Extended area means the idea, that wechoose items not only in the learning

    area, that means under the level of

    competence.

    To produce some dynamic and thechance to get a higher level, we add

    now .15 to the actual estimation of the

    degree of competence of the student

    Infomationprocessing

    The matrix at the left shows the history: The beige colour

    indicates well known results, the brown is one rightanswer. The rabbit comes from left to right to the carrot

    and catches one - if the pupil produces consecutive right

    answers.

    Study first research study was carried out at a primary school in Austria.

    Begin: summer semester 2011

    42 pupils of the primary school Laubegg (age: 9-10).

    at least 4 weeks. Some of the learners ignored this time restriction andplayed the game again and again over months.

    Learners learned on computers at the school as well as on their

    personal computers at home.

    12.926 answers where given which means that on average each learneranswered 308 questions- they did 3.4 times the whole multiplicationtable.

    Bearing in mind that there was no real pressure from teachers sideusing the program it is a considerable pleasant high number.

    Furthermore it can be stated that pupils seemed to enjoy using theapplication or at least get not bored.

    We dont know

    More than half of the learners did not reach the 100 percent level

    (= 90 items are well-known). Therefore we have to think aboutthis group of learners: Perhaps they

    didnt get used to / have problems with the interface

    do not know the necessary operations; are not able to solve

    the learning problem correctly

    misinterpret an assignment

    are distracted by the environment

    are badly concentrated for several reasons.

    Could we gather more information to know more?

  • 8/2/2019 120430-lak12

    Analyses

    Ill show here some graphs of the collected statstical data.

    We made the experience, that the teachers in our interviews

    are interested in very short compact information,

    overviews.

    We fear, that if we would produce too much information the

    teacher would than reject the entire system .

    Demotivated learner

    One learner with a weak

    performance attracted our attentionbecause of a very high number of

    trials (513). A detailed inspection

    showed that he did not work very

    intensively. In the first two tasks

    he/she failed, then eleven tasks

    were ok, his performance rose

    abruptly. However, afterwards, hecontinued approximately 400 times

    to wait the whole answering time

    without doing anything but asking

    for a new assignment.

    Motivated Captain

    The most diligent learner.

    In the beginning, theassignments were solved

    correctly, then some mistakes

    occurred, afterwards a

    learning process can berecognized and finally with

    some occasional mistakes the

    learner works on a high

    performance level.Obviously, the learner was

    highly motivated to deal with

    the assignments given by the

    program.

  • 8/2/2019 120430-lak12

    27/33

    Medium LearnerIn the beginning, the learner made

    mistakes in every second

    assignment (0.5), followed by 7mistakes consecutively. This is the

    reason for the big decrease (0.15).

    Afterwards, the learner gave a

    number of right answers and the

    rate of correct answers increased

    back to 0.5. In the following phase

    an up and down can be seen till a

    number of right consecutive

    answers helps to reach a level of

    0.7. But then the number of

    mistakes rose again and the rate

    went down to about 0.5.

    Summary

    It is as easy as never before to collect data

    We perceive much more details about the

    learners the learning process as never

    before!!

    Teacher get precise information (class lists

    are coming soon)

    This application was designed to test. Now

    we see, it can be effectivly used for learning

    Future Work

    closer look at the learners: perhaps more intelligentanalyses of the data? more data more concepts?

    Hints for Learners?

    Special Results for Teachers

    Alerts for Teachers

    AND we are already working on the Mathe-Multi-Trainer

    (multi digit

    multiplication:http://mathe.tugraz.at/~mickname/access/login

    )
