Expert Validation of a Python Test, Reliability, Difficulty and Discrimination Indices

In recent years, different countries have implemented the teaching of computer programming from first grade in schools, with aim incorporating computational thinking as a new way that is necessary skill for scientific and technological development, fundamental axis development 21st century. Recent reviews state art shown this task only being carried out by given space to technology science, it at elementary school level. However, developing do not yet consider significance issue, so date they taken steps direction. addition, learning join can be creators just users it. The problem there no didactic programming, nor validated evaluation instruments quantify programming. objective research validate test evaluates technical skills Python language. instrument proposed 90-item test, which after validation experts was reduced 70 items, psychometric analysis considered calculation reliability, difficulty discrimination indexes, resulted 45-item instrument, standard It should noted methodology using classical theory analysis.
