| STUDI DI SOCIOLOGIA - 2010 - 1
The article aims to contribute to the debate concerning the value and potential of using
internet as a social research tool, investigating if the mere transfer of traditional survey methodological procedures to an online setting would be sufficient or, instead, it would need to be modified in order to realize a web survey. Showing the structure and main peculiarities of two online questionnaires concerning evaluation activities of an adult training course (with samples of over 15.000 learners and nearly one thousand e-tutors), the article analyses advantages and drawbacks of online methodology compared to the standard «paper-format» survey. Facing methodological issues (like sampling procedures, generalizability of the results, statistical representativeness, data and answers quality, tool personalization) the study shows some elements (objectives of research, population, target) through which the use of an online setting would lead to better results in comparison with a traditional questionnaire.
Key words: web survey, internet research methods, questionnaire methodology, Computer Assisted Data Collection, data quality.
