ACTA TECHNICA CORVINIENSIS – BULLETIN of ENGINEERINGimplementing them. By using computer thelearning potential is huge. The computerprovides students and teachers "the opening" tothe world, to the others. He gives the student theway to overcome isolation. For teacher andstudent altogether, the computer represents agreat help during classes and elsewhere.Weaknesses for computer use:it affects the child's posture;it enlarges diopters;it determines aggressive behavior due togames;it allows the child to relate to unknownpersons.Strengths for computer use:the child learns to control an instrument byplaying;it improves hand eye coordination;it speeds up the reaction;it offers the opportunity to explore the worldand create original work;it facilitates the interpersonal relationships;the child gets a good opinion of himself;it improves his school performances.To students, the computer has only strengths.The interactive software has a strategy thatallows feedback and ongoing monitoring,resulting in an individualization of coursedepending on the subject's knowledge.Following the analysis we did to achieve thiswork, we can say that the main features ofcomputer assisted instruction are:ensure unity among the functions ofcommunication, storage and control,resulting in improved learning by feedbackeffect;exempt professor from teaching a series ofacts of routine (teaching, repetition,evaluation, etc.), thus giving him theopportunity to focus his efforts and time torefine studied material (by steps andinvestigation);require combining the study by reading themanual or the computer with otherbibliographic materials and experimentrequire maintaining the relationship"teacher-student" working in groups or withthe whole class to confront the results, tocreate that climate, develop a sense ofcommunity;provide an active reception of knowledge,depending on students working at their ownpace;teach students self-control and managementof their intellectual activitiescreate the possibility to revise the poorlyunderstood problems and thus to make aconscious approach to knowledge.The educational software designed forsimulations and virtual experiments to teachchemistry lessons has the following advantages:allows teachers and students to create fast,easy and secure virtual experiments neededto understand certain phenomena;there are no actually consumed substances,no broken utensils, no materials, which areusually very expensive;there is no toxic working environment as ina chemistry laboratory;accidents are eliminated when conductinghighly dangerous experiments;virtual experiments can be achieved in amuch shorter time, thus saving time;virtual experiment to determine thechemical nature of a solution cansuccessfully replace the real experimentwhen it does not exist in the laboratory.The use of AeL platform and its own programslead to a teaching-learning process moreefficient and attractive to students and teachers.The use of computer in teaching Chemistry hasboth advantages and disadvantages:ADVANTAGESthe use of computer provides a high degreeof individualization and independence oflearning, ensuring the reverse learning linkthrough feedback, the amount of acquiredknowledge is being increasedcomputer assisted learning provides a selfpacedlearningit ensures a conscious knowledgeacquirementit sequences the scientific contentit facilitates the ongoing evaluation of resultsDISADVANTAGESthe poor endowment with computers leadsto the fact that students can not worksimultaneously, moreover, not all studentshave the same skill in computer usea depersonalization of teaching-learning actexcessive individualization of learning canlead to denial of student-teacher dialogue2010/Fascicule 2/April­June /Tome III 83
