Relevance of Mastery Learning (ML) in Teaching of English (Case Study of the University of Guilan, Iran)  [PDF]
Abbas Sadeghi, Atefeh Sadeghi
Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.31007
Abstract: The main purpose of the study was to gather, analyze and interpret the perceptions of the students about mastery learning (ML) held by 240 students randomly selected from each of the populations of different faculties in Guilan University. Guilan University was chosen because the researchers have some valuable experiences about English learning and are familiar with students’ weakness in English learning. The students of high ability were allocated to “A” and “B” classes, average to “C” and “D” classes and low to “E” and “F” classes respectively. Two Academic Staff Members were assigned to teach the six classes of English. Students could take 3 classes with each academic. Results showed that based on research results on deep and surface, biased learners increasingly which became surface learners did worse compare with deep learners. On the other hand, surface students of low ability seem to be motivated to study as they are given more chances to secure a pass. Thus, although the findings of this paper indicate that mastery learning promotes better quantitative results in English for surface learners, there are dangers. One of the main aims of learning to increase higher level cognitive processes seems actually to be discouraged in this mode.

Open Journal of Geology (OJG) , 2013, DOI: 10.4236/ojg.2013.31003

In this research, the Turonian-early Campanian sedimentary succession of the Abderaz Formation with 510 mthick (comprising: light grey shale and marls) was studied in the type section in eastern Kopeh-Dagh basin. The statistical analysis of the morphotype groups of the identified planktonic foraminifers shows that most of them are shallow water forms (SWF) and deep water forms (DWF). The high planktonic to benthic ratio indicates particular oligotrophic conditions and sedimentation in relatively deeper zones of a marine environment. The salinity of sea water during Coniacian was in the minimum level, whereas it reached maximum in Coniacian-Santonian boundary. Comparing Planktonic assemblages from the study formation with those from the Cretaceous biogeographical provinces reflects a close relationship between the identified species and the planktonic forms of the Tethyan provinces.

Health (Health) , 2015, DOI: 10.4236/health.2015.77105
Abstract: The main goal of this research was the scrutiny of relationship between students’ personality characteristics and mental health at the University of Guilan. The population was the students of the Faculty of Humanities in 2009 with 3000 which 196 were selected using Kerjeci & Morgan table and stratified sampling method. They answered to the NEO and GHQ questionnaires. Results showed that there was relationship between personality characteristic of neurotic, openness, extraversion and being conscionable with mental health. Meanwhile, openness had the highest and extraversion with the lowest correlation scale and most of students (65%) had low mental health. Also, there were no significant differences among students with respect to different courses but significant difference with respect to gender and age.

Psychology (PSYCH) , 2015, DOI: 10.4236/psych.2015.616212
Abstract: The purpose of this research was to investigate the relationship between positive self-concept and success academic staffs at University of Guilan where 281 out of 500 contractual, official-experimental and official academic staffs were selected by simple random sampling in 2014-2015 academic year. The amount of effectiveness of factors such as academic staffs’ responsibilities, risk taking, strong self-concept (feeling of merit and evaluation) on their position has been measured in this research. Research questions have also measured manager’s personal traits (gender, age, and education level, field of study, work experience and teaching experience). For collecting information of this research which is correlation type, two questionnaires with 51 questions have been used in Likert spectrum. The results showed that there is a significant relationship between positive self-concept and success of academic staffs’ variables and personal traits which are female and male academic staffs’ education degree, work experience, professional experience and faculty. Also, behavioral sciences academic staffs (psychology, counseling and social sciences) generally had higher positive self-concept.

Open Journal of Geology (OJG) , 2013, DOI: 10.4236/ojg.2013.33028

The main purpose of this paper is the sequence stratigraphy and biostratigraphy of lower Tertiary sediments on the base of larger benthic foraminifera in northeast of Iran (Chehel-Kaman Formation). This formation mainly consists of Limestone, dolomite and interbeds of sand, shale and evaporate sediments. Petrographical studies indicate that these sediments may have been deposited on a shallow carbonate platform ramp and consist of 4 carbonate lithofacies (15 subfacies). These lithofacies may have been deposited in open marine, shoal, lagoon and tidal flat environmental conditions. Sequence stratigraphy analysis led to identification of 4 third-order depositional sequences, bounded by type 2 (within the top of the underlying Pestehleigh Formation) and type 1 sequence boundaries (paleosol). Interpreted sea level curve in this basin can be relatively correlated with global curves during Paleocene time and a with a sea-level fall occurred in the latest Paleocene, followed by a rise in the earliest Eocene. Biostratigraphy study led to the identification of 32 larger benthic Foraminifera genera. The Paleocene/Eocene boundary has been probably recorded as a thin red paleosol horizon (~10 - 15 cm).

Abstract: Saccharomyces cerevisiae (baker’s yeast) is the most important industrial microorganisms. This yeast is commonly used as a leavening agent in baking bread and bakery products, where it produces carbon dioxide from converting of the fermentable sugars present in the dough. Nowadays, industrial and chemical activities led to produce new compounds with new kinds of contamination in the environment. Discharge of untreated or partially treated industrial sewage has created the contamination problems of rivers and lakes such as drugs, oil, heavy metals, paints, pesticides and various chemical compounds in them. Hence, it is necessary to control and reduce the levels of these compounds in wastewater and bring them to permissible values. This study aims to study the bioconversion potential of commonly available Saccharomyces cerevisiae for the two textile dyes of Carmoisine and Reactive Black 5. Reaction mixtures for biotransformation of dyes included 50 mg/l Carmoisine or 25 mg/l Reactive Black 5 and 1% dried harvested cells of S. cerevisiae (bread’s yeast) were tested. Harvested dry and wet yeast were studied for this purpose. The results show that harvested cells of Saccharomyces cerevisiae are able to bioconvert Carmoisine and Reactive Black 5. Reactive Black 5, Carmoisine are degraded by biotransformation 85% and 53% within 24 hours in water at the room temperature.
Survey of the Relationship between Personality Types and Burnout among Teachers at First Period (Guidance School) and Second Period of High School (Secondary School) in the City of Rasht, Iran  [PDF]

Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.68086
Abstract: This research investigated the relationship between John Holland’s personality types (realist, investigative, conventional) with burnout among female and male teachers at first duration of high school (guidance school) and second duration of high school (secondary school). For this purpose, 327 persons were selected by multistage cluster sampling method. In order to gather information, Meshach burnout questionnaire and John Holland’s job-personality questionnaire were used. Descriptive and inferential statistic methods were utilized to analyze the data. It was worth mentioning that Pearson correlation coefficient r, linear regression and the analysis of multivariable variance (MANOVA) were used to measure the relationship between predictor and criterion variables. Obtained results by the investigation of relations showed that there was a reversed relationship between personality types and the degree of burnout, with correlation coefficient of r = (–2.24), respectively, in the level of (p = 0/01). The relationship between realist, investigative and conventional personality types with burnout which was calculated by (r = –1.15, r = –1.84, r = –2.19) respectively, was significant and reversed. It was necessary to say that among demographic variables (gender, age, precedent, education and teacher’s marital status) there was just a significant relationship between gender, personality type and the degree of burnout in the level of (p = 0/05). It showed that from the view point of gender there was a significant difference between burnout. The degree of burnout in male teachers was more than female, and there were no significant differences in other demographic variables. The most important application of this study is that everybody will be employed according to his/her job-personality type to avoid any physical and mental damages arising from working.

Abstract: The main objective?of?this?study was to compare learning styles, resiliency and problem solving skills in Iranian chess players. The approach?of?this?study was a description of cohesion kind. The statistical population included all active chess players with an international rating under chess federation supervision of Islamic Republic of Iran. The sample was based on Morgan table, and the sampling was done by simple method and the number of 306 players was?chosen who answered the learning style questionnaire of Clop in2005,Kaner& Davidson’s Resiliency in 2003, and Kasidi& Long’s problem solving?guideline in 1996. The data obtained by Chi-square Test, Kolmogorov-Smirnov Test (KS test), Kruskal-Wallis Test & Spearman correlation Test analyzed by SPSS21. The findings showed that there wasn’t a significant relationship between learning styles with the amount of resiliency and chess players’ problem solving skills. Also there was a positive and powerful relation between the amount of resiliency and chess players solving problem skills. It seems that chess players learning style doesn’t have any effect on the ability of problem-solving skill. In other word,?having learning style and different thinking?isn’t an advantage

High resolution sampling across the Cretaceous/Paleogene boundary (K/Pg) at the Galanderud section in northern Iran provides the most expanded and continuous section for us to consider biostratigraphy and the mass extinction pattern of Cretaceous planktic foraminifera. Based on planktic foraminifera, four biozones and five sub-biozones have been identified across the K/Pg boundary. These biozones include the Abathomphalus mayaroensis Biozone (Plummerita hantkeninoides subbiozone), the Guembelitria cretacea Biozone (including two sub-biozones: the Hedbergella holmdelensis and the Parvularugoglobigerina longiapertura), the Parvularugoglobigerina eugubina Biozone (including two subbiozones: the Parvularugoglobigerina Sabina and the Eoglobigerina simplicissima) and finely the Parasubbotina pseudobulloides Biozone. Planktic foraminiferal extinction occurred over a brief period, with 3% of the species disappearing in the late Maastrichtian, and 72% of the species becaming extinct at the K/Pg boundary. About 25% of the species survived into the early Danian. Extinction of 73% of the species at the K/Pg boundary is very compatible with the effect of a large asteroid impact.
