V prispevku predstavljam možnost avtomatskega preverjanja znanja osnov računanja v množici celih in racionalnih števil. Kviz pripravljen v okolju Moodle učencem generira 20 naključnih računov iz seštevanja in odštevanja celih oz. racionalnih števil, eno vprašanje dopolnjevalnega tipa in eno esejsko vprašanje, kjer učenci opišejo postopek seštevanja oz. odštevanja celih oz. racionalnih števil. Čas reševanja je 35 minut. Po preteku tega časa se kviz avtomatično zapre, zaključi. Sistem učencu takoj poda povratno informacijo: skupni čas reševanja, (ne)pravilnost rezultatov, število doseženih točk, odziv in usmeritev glede na dosežene točke. Zaključeni kvizi  učitelju nudijo takojšen vpogled v oddane odgovore, pravilnost le-teh in torej tudi znanje tako posameznika kot skupine. Rezultate se lahko analizira prek preglednic in grafov, s tem je dan takojšen vpogled v morebitna odstopanja – slabo rešene naloge, odlično rešene naloge, učence s šibkim znanjem... Pri tem kvizu gre za preverjanje minimalnih standardov znanja na nivoju poznavanja in razumevanja matematičnih pojmov in dejstev ter uporabe enostavnih postopkov, ki pa morajo biti nujno usvojeni, če naj bo nadaljnje napredovanje uspešno.

Abstract

Featured article presents a possibility of automated assessment and evaluation of basic math skills. The article shows a quiz with 20 calculated type questions using Moodle. Moodle generates 20 calculus math problems of adding and subtracting random integers and random rational numbers. The quiz has one embedded answers (Close) question type and one essay question type for students to describe procedure of adding and subtracting inside set of integers and set of rational numbers. After 35 minutes is automatically closed. Moodle gives immediate feedback. Students can see the results and responses, total number of points, their grades. For teacher, completed quizzes provide instant access to submitted answers, their correctness, level of mathematical knowledge of students – as individuals or as a group. Results can be analyzed by tables and graphs. They present immediate insights into deviations – poorly resolved tasks, perfectly solved tasks, students with no mathematical knowledge... Featured quiz was set to check the minimum standards and basic math skills, understanding of mathematical concepts and facts at the level of simple procedures which must be acquired in order to make further progress and new mathematical achievements.
