the considerable growth of information and communication technology and its excessive influence on different aspects of life have affected many activities , especially educational activities such as changing students educational requirements , students and teachers essential skills , teaching methods , and the application of information and communications technology in the process of teaching . the ability to accommodate oneself with the changes , competitiveness , and lifelong learning are the means of success in the contemporary society . to reach to this objective , we need much further capabilities and skills than physical skills and financial assets . excessive increases of information resources from one hand and rapid advancements of other sciences on the other hand have made students unable to learn the whole materials in their normal educational courses . this is why helping students on how to learn , in other words training lifelong learners , is among the most important tasks of educational institutes . students should be able , after they graduation , to continue their creativities and reach to higher levels of education by combining their new and old information sets . what it takes to reach to this level is having special skills known as information literacy . in fact , information literacy is the most essential requirement of students in information society . information literacy is a set of information needed for searching , recovering , evaluating , and making best use of information . the most comprehensive definition of information literacy ever is by american library association as follows : to be information literate , a person must be able to recognize when information is needed and have the ability to locate , evaluate , and use effectively the needed information . undoubtedly , students access to information and their benefit of critical thinking leads to their active partnership in educational activities . although there is a direct relationship between information literacy and educational activities such as formal and informal , little study has been done on this relationship either in iran or abroad . hasanzadeh and asadi have directed a study on the effects of teaching information literacy on the academic performance of students in imam mohammad baqer technical higher education center in sari . it proved that there was a significant difference between the academic performance of the two groups of testing and control , the ability to recognize and specify information needs , getting skills at locating and accessing information , getting related skills at using information effectively and responsibly , the way of using information resources at libraries . pandpazir and cheshmeh - sohrabi found that ma students at kermanshah university of medical sciences were good enough at understanding information need , strategies for searching information , locating and accessing information , using information , combining new and old information sets , and evaluating search results to meet their information need . totally , the level of information literacy of ma students at kermanshah university of medical sciences was higher than medium . bigdeli and momtazan found that students at jundi shapur university of medical sciences in ahvaz ( international unit ) were more information literate than nursing students ; but in total , statistical population had medium information literacy . subjects were at a medium level for searching their needed information at libraries , using computers and accessories , having self - confidence when searching for information , evaluating retrieved information , being satisfied with search results and asking for help from librarians , but they were at a low level for searching their needed information from internet and working with logical operators . information literacy for senior students at razi university of kermanshah  done through descriptive survey by questionnaires , found that students of different majors were in different levels of information literacy as students of mechanic and computer engineering were at the highest level and theology and arabic literature were at the lowest level . studied information literacy level and its role in learning process of electronics students in the department of electronics in amir kabir , shiraz , and science and technology universities . second , there were different levels of information literacy as the highest was standard 1 and the lowest was standard 4 . third , there was a significant positive relationship between information literacy and electronics students academic performance like the higher the information literacy level , the better the academic performance . bordonaro studied the relationship between information literacy and writing ability in the two groups of international graduate students and undergraduate students . the results showed that in the graduate students group there was a significant relationship between two variables while there was no significant relationship between variables in the other group . baro and fyneman found that male students not only were more aware of information resources , but also they could use these pieces of information more effectively than female students could . issa et al . found that students at ilorin university were not able to use information resources effectively , although they were aware of them . moreover , even though students were hardly information literate , only librarians were responsible to teach them these needed skills . as was observed , most of the studies , especially those done in iran , mainly deal with analyzing information literacy among different groups and only a few of which have inspected the effects of information literacy on different variables specifically on academic performance . thus , the main object of this study is to specify the relationship between information literacy and academic performance of students at isfahan university of medical sciences . statistical population is all ma students at isfahan university of medical sciences in 20122013 . according to the statistics obtained from university education office , they were 859 students . according to the sample size determined by using the cochran formula , data collection was through information literacy questionnaires designed by davarpanah and siamak , verified by library and information sciences experts ; and finally gave a cronbach 's alpha of 0.83 . this questionnaire evaluates the ability of nature specifying , the extent of information needing , the ability to get needed information , evaluate the retrieved information , use information effectively for the same purpose , and helps understanding economical , legal , and social issues . as some questions had more than one correct answer , we considered one point for every correct answer . hence , the least point for information literacy was 0 and the most was 33 , and the average point was 16.5 . to determine academic performance , data have been analyzed in the two levels of descriptive and inferential statistics . in the level of descriptive statistics , we have used frequency distribution , mean , and sd and for inferential statistics , we have used tests such as one - sample t - test , independent - samples t - test , and pearson correlation . the study about participants sex showed that 83.4% of whom were female and 16.6% were male and also 17% were from health faculty , 25.7% from nursing faculty , 27.2% from medical faculty , 6.8% from nutrition and food sciences faculty , 9.4% from rehabilitation faculty , 4.9% from pharmacy faculty , and 9.1% from management and medical information faculty . table 1 shows the students information literacy level in different departments . to analyze students information literacy level students information literacy level is significantly more than the average , that is , 16.5 except for nursing , midwifery , nutrition , and food science students . in addition , students in medical management and information department had the highest level of information literacy and nutrition , and food sciences had the lowest level . ( test value=16.5 ) to compare male and female students information literacy , we used independent - samples t - test . the results of independent samples t test for female and male student 's information literacy level to specify the relationship between information literacy and academic performance , we used the pearson correlation test . there is a significant positive correlation between the two variables , considering correlation coefficient and significant level . to compare male and female students information literacy , we used independent - samples t - test . the results of independent samples t test for female and male student 's information literacy level to specify the relationship between information literacy and academic performance , we used the pearson correlation test . there is a significant positive correlation between the two variables , considering correlation coefficient and significant level . being a lifelong learner is one of the key factors that makes us successful in the information community . on the other hand , information literacy is a set of skills necessary for recovering , evaluating , and using information . considering the relationship between information literacy and formal and informal educational activities , this study has an objective to analyze the relationship between information literacy and academic performance of ma students at isfahan university of medical sciences . the findings of the study showed that all students were good enough at information literacy , higher than the average level , except for the students at nutrition and nursing departments . these results were consistent with those of pazir and cheshmeh - sohrabi and different from those of bigdeli and momtazan , seyfori and ghafari , alinejad et al . , and issa et al . according to this study , there was no difference between male and female students information literacy level . these results were consistent with those of hassan zadeh and asadi and alinejad et al . and different from those of bordonaro . considering the direct relationship between information literacy skills and students academic performance especially in ma students , we suggest , in order to increase the level of information literacy skills , educational courses in the form of workshop should be presented on items such as searching , having a critical mind , correct methodologies for studying , writing essays , research attitude etc .
