- چکیده انگلیسی: Introduction: Following the growing development of information technology, the traditional methods of teaching cannot meet the teaching demands of today’s societies. The Purpose of this study was to compare the effects of the modern and traditional teaching methods on knowledge and attitude of the dental students. Materials and Methods: This study is a semi experimental one carried out in the academic year, 2012. The participants consisting of two groups of dental students were selected through random sampling. One group was taught through the traditional method and the second group through the multimedia method. Then a written test was given to the two groups about the lesson contents, and the satisfaction level of the groups was determined, using the 0-10 scale. After two months, a test was performed in order to investigate the rate of remembrance. The Manweitny statistic test was used in order to analyze the data. Results: The level of knowledge for the group taught through multimedia method was more significant than that for the group undergoing the traditional method. However, the mean of satisfaction grade and remembrance were found not be significantly different. Conclusion: Regarding the effectiveness of the multimedia method, the use of this method can provide a good opportunity for students to learn better.

- چکیده:
- چکیده انگلیسی: This study was conducted to identify and recognize relations and diversity among accessions of the Iranianpears (Pyrus spp). A total of 34 pear accessions, derived presumably from at least six species, were subjected to simple sequence repeat (SSR) analysis. The Japanese and the Chinese pear samples were; “Housui” and “Yali” cultivars, example of Pyrus pyrifolia and P. bretschneideri, respectively. Some European pears and Iranian germplasm were analyzed. Seven SSR markers (KU10, BGA35, BGT23b, NH011b, NH013a, NH004a and NH015a) were used for the analysis. One hundred six visible amplified fragments (putative alleles) acquired for 34 pear samples NH011b and NH015a loci exhibited high heterozygosities of 0.82 and 0.79, respectively. BGA35 produced eight putative alleles, while NH013a created 22 putative alleles. The average value of allele per locus was 15. A phenogram was constructed based on the similarity-matrix data using the unweighted pair-group and arithmetic average methods. There was no association between the SSR and morphological phenograms. This work revealed relatedness of Iranian pear samples to the four species of P. communis, P. syriaca, P. salicifolia, and P. glabra.
