The technique is closely associated with the scientific development at all the human knowledge fields specially the educational field at all specializations of different educational levels. Libraries and information is one of specializations that is obviously affected with the technique and the technological innovations due to services and educational activities it offers and which are useful for all practical and scientific specializations inside the educational institutions.

     One of the most important functions of  libraries and information centers is to collect the information vessels form their different sources and prepare them technically to facilitate their benefit quickly and with less effort. So, it was necessary to organize these information in away that facilitates reaching it if there is a need. Designing, producing and developing the Bibliographic lists is one of these most important functions and services (Ali Abd Almonem, 1995, 8- 15).

   'Bibliography' curriculum that fourth year students of  Libraries, Information and Educational Technology at faculty of Education, Al- Azhar university studies as one of  their preparing programmes is considered one of the practical curriculum that aims to give students the practical procedures related to the Bibliographic data sheets production skills to enable students to practice skills well before joining the work field.

     The researcher has observed  that ' Bibliographic'  curriculum handles- from its practical and theoretical sides- the Electronic Bibliographic data sheets production from its true concept as it weakens students and leads them to be unable to produce the Electronic Bibliographic data sheets.

     So, this leads to think of developing the skills of the Electronic Bibliographic data sheets production skills. This is considered as a step of developing 'Bibliography' curriculum. This results from the fact that one of  Libraries, Information and Educational Technology specialists basic tasks is to prepare, produce and make all educational systems available to all educational institutions to benefit all the educational process.

     So, there is a need to search for learning techniques that enable students to continue their studies without travelling difficulties and that achieve some kind of similarity between these skills and the used techniques of learning. Hence, thinking of using one of the modern  Flipped  Learning  Environment  that can be practically achieved through the Flipped Learning Environment.

     The concept of the flipped learning is based on exposing students to the educational content outside the classroom either through an educational video that is prepared by the teacher or through readings related to the lesson subject, then using the classroom time for understanding and representing these knowledge through practical performing, problem solving, discussion or dialogue.

     It is worth to show  that  learning is no longer considered with the amount of knowledge that person knows. It is considered with what  the person can achieve according to his knowledge.

     From this point, the Flipped  Learning  gives students a chance to practice the educational activities and apply what they have studied whereas activities that the  Flipped  Learning is based upon is very significant, its role can't be ignored and also can be handled and presented in different styles.

     In this research, two styles of the educational activities practicing at the Flipped Learning Environment; the individual activity practicing against the cooperative one will be handled.

     Thus, the search idea comes to the searcher that aims to identify the Effectiveness of the Difference of two styles of doing activity at the Flipped Learning  Environment on developing the Electronic Bibliographic data sheets production skills with Libraries, Information and Educational Technology Students.
