Currently, in the researches of library and information sciences, the relationship between the process of searching and learning is discussed a lot. It seems that the search to learning has led to exploratory search and exploratory search has helped users discover concepts in order to overcome their uncertainty and finally, achieve learning. What has been neglected is the extent to which searching process affects learning and the degree of knowledge change until one reaches the level of expertise. Hence, the present study was compiled on research findings with the aim of determining the impact of the information search process based on work tasks on learning. For this purpose, a semi-experimental one-group design with pre-test and post-test was used in 2021. The statistical population was the nursing students of the Bushehr University of Medical Sciences in their sixth semester, and 38 of these students randomly participated in this study. First of all, an educational workshop with the aim of getting familiar with drawing conceptual map and a search training workshop were held. Afterwards, the students were assigned two tasks and they were asked to draw their conceptual maps before and after searching. In order to describe and analyze the information in this research, conceptual map scoring (a type of quantitative content analysis) was used to determine the degree of learning, the Euclidean algorithm was used to assess the degree of knowledge change until reaching the level of expertise, and the pairwise comparison method was used to evaluate the difference in the degree of learning before and after the search. The outcomes indicated that the mean difference before and after the search was significant in both scenarios (P<0.001). Also, there was a significant difference between the mean scores before and after the search and the score of the conceptual map, with high confidence. However, it was low, compared to the rate of learning growth according to the expert score. Besides, the difference between the mean of the conceptual map in the complex and simple scenarios was not significant. The results demonstrated the effectiveness of search as a learning method, so it is suggested that librarians and information professors introduce searching as a learning method along with other methods to increase awareness and develop creative thinking skills in the academic community.

The Concept maps of Chemistry can be obtained from the thesaurus of Chemistry. Analysis of information in the chemistry field of science at the graduate level is done, based on the comparing and analysing the Chemistry dissertations by using this maps. Therefore, the use of thesaurus for analysing scientific information is recommended. The major advantage of using this method, it is possible to obtain a detailed map of all academic researches across all branches of science. The researches analysis results in chemical science can play a key role in developing strategic research policies, educational programming, linking universities to industries and postgraduate educational programming. This paper will first introduce the Concept maps of Chemistry. Then, the emerging patterns from the Concept maps of Chemistry will be used to analyse the trend in the academic dissertations in Chemistry, using the data collected and stored in our database at Iranian Research Institute for Information Science and Technology(IranDoc) over the past 10 years (1998-2009).

Concept mapping is a cognitive strategy particularly suited to identifying relationships between ideas. This study has investigated the effectiveness of concept mapping as a learning strategy on intermediate students’ listening comprehension. Although listening comprehension is now well recognized as an important aspect of language learning, it has been neglected in research and practice until quite recently. Even now we cannot say much work has been done in this domain.By administering a Comprehensive English Language Test (CELT), a sample population of 60 subjects was selected from 91 students of English translation in Islamic Azad University, Islamshahr Branch. A pretest consisting of six listening passages was administered to the subjects. After one month, training sessions were devoted to the experimental group and appropriate concept maps were provided before listening to the passages to teach them how to listen, whereas some pictures were used to teach the control group. During the special instruction by concept mapping technique,the researcher asked the students to help her in writing the concepts in order to determine their level of involvement. Their level of involvement was measured by a questionnaire that they had answered in the last session later on. The obtained data was analyzed through t- test. The analyzeddata presented that; there was a significant difference between the means of experimental group and control group on the post- tests. That is concept mapping proved to be effective and has increased the experimental group’s listening comprehension.By investigating the questionnaire it was realized that 70 percent of the students had helped the teacher in mapping the concepts that indicates a good level of involvement in the teaching- learning process. On the whole, the findings suggest that it is necessary to provide FL listeners with the appropriate learning strategy prior to asking them to listen. On the other hand the instructors should not ignore the critical role of learning strategies in FL listening comprehension.
