The Cody math test Cody M 2-4 ( Co mputergestütztes Dy skalkulie test procedures and training) is a diagnostic procedure , the finding of calculating or dyscalculia in primary school children which is used to 4. 2nd class. The CODY math test was developed in 2013 as part of the CODY project at the Institute for Psychology at the Westphalian Wilhelms University in Münster in cooperation with the Düsseldorf software developer Kaasa health . He creates a differentiated profile in which the child's basic mathematical and arithmetic skills are recorded. Since March 2018 the CODY-M 2-4 has been part of the S3 guideline for the diagnosis and treatment of dyscalculia, which was initiated by the German Society for Child and Adolescent Psychiatry, Psychosomatics and Psychotherapy eV (DGKJP) and made up of 20 scientific specialist societies and professional associations in the areas of psychology, education, medicine, didactics and learning therapy.
commitment
The dyscalculia test procedure is part of the math training software Master Cody - Talasia . It records the basic mathematical skills of the child at the beginning and during the course of the training (after 30 days). In addition, it is used as part of the CODY project, in which numerous primary schools are involved, to investigate the development of the mathematical competencies of primary school children using various training methods.
construction
The Cody math test takes about 40 minutes and covers the four skill areas of basic number processing, complex number processing, arithmetic and working memory. It comprises several subtests that test different math and cognitive skills:
- Response time test
- counting
- Quantity comparison (symbolic and mixed)
- Dictation of numbers
- Arithmetic (addition, subtraction, multiplication, placeholders)
- Number stones
- Number line
- Matrix span
- Missing number
The subtests are largely based on the findings of Brian Butterworth, who in 2003 developed the basics of a computer-aided screening process for the detection of dyscalculia.
evaluation
The test evaluation is carried out by the University of Münster. The test results are compared with a reference sample made up of more than 600 pupils in grades 2 to 4. The test results are presented in the form of percentile ranks, which indicate how well the child performed compared to other children in the same grade level. An overall value is determined from the four partial values of the individual skill areas. The validity and reliability of the test procedure have been extensively tested. The specificity of the CODY math test is 81 and the sensitivity 76. The RATZ index is given as 0.68, which shows that the measurement accuracy of the CODY math test is high.
