Error analysis - Journal

These  pages  demonstrate  how  user's  performance  is  analysed  and  what  you  gain  using  this  option.  The  Journal  shows  a  record  of  four  performed  tasks  with  grades  (marks)  and  summaries  of  errors.  The  performed  tasks  are  analysed  severally  and  jointly.  You  can  observe  an  analysis  of  errors  for  each  task  separately  (magnifier  icon).  Furthermore,  you  can  proceed  to  the  results  of  joint  multifactor  analysis  of  a  set  of  performed  tasks  and  find  methodical  recommendations  for  development  of  missing  skills.  The  function  of  performance  analysis  is  only  available  in  the  program  EMMentor.  With  EMMentor  you  can  get  your  work  analysed  with  same  degree  of  detalization.  EMMentor  will  detect  all  vacancies  in  your  knowledge  and  skills  and  show  the  way  to  improve.  At  the  bottom  of  this  page  we  offer  you  to  try  examples  of  learning  techniques  available  in  the  program  EMMentor.
