THE MATHEMATICAL SKILLS AND TIME AVAILABLE IN STANDARDIZED TESTS

The research project sets out to inv variable in the performance of INVALSI math tests in Italian students of secondary school. The INVALSI tests are standardized tests, based on articulated and rigorous procedures, for Italian school students. Evaluation of INVALSI tests is mandatory by law (Article 51 paragraph 2 of the Decree-Law of 9 February 2012, No. 5 converted into law No. 35). The tests are elaborated by the National Institute for the Evaluation of the Education and Training System (INVALSI), a public law research body of the Ministry of Education, University and Research (Miur). The purpose of the tests is to draw a statistical reference framework on the level of learning in Italy. With the INVALSI tests it is possible to monitor the national education system and compare it with other European institutions. The INVALSI Test carried out at the conclusion of the Third-Degree State Examination of lower secondary school was an instrument for the certification of Fondazione Giovanni Agnelli 2014, p. 68). A study of 2011 (Chamberlain, Daly, Spalding), aimed at exploring the causes that trigger the examination anxiety, highlighted the importance of time available to complete the test among the causes. The time allotted to carry out a test or, in any case, the perception that students have of it can therefore be an element to be taken into consideration because it could alter the measurement of learning. Specifically, the survey aimed to perform a statistical analysis of the performance results of a sample of 137 students when the time variable varies. In particular, we wanted to establish if the time variable influences a different expression of skills. In first analysis it would seem that the time factor does not have d performances, but Rasch analysis has shown that the time difficulty level of each item of the math test. Finally,
