Iranian EFL teachers’ effectiveness of instructional behavior in public and private high schools

Over recent decades, educators have recognized the crucial importance of teaching environment and contextual factors in teaching and learning outcomes. Public and private schools are among those teaching contexts that have been in competition for teaching quality and effectiveness for many years. This study investigated the effectiveness of some English teachers in these two school contexts in a foreign language setting, Iran. Seventy-six public and private high schools in a small city in Iran were selected, and their English teachers’ performance was evaluated by an external observer and self-evaluation using a high-inference observation instrument and a questionnaire. The result of the data analysis showed that English teachers who worked in private schools were more effective teachers than their colleagues in public schools. The results also revealed that teacher effectiveness and their years of teaching experience and age were weakly but significantly related. Furthermore, it was found that teachers’ type of university degree and the location of schools (disadvantaged vs. privileged areas of the city) were not related to teachers’ effectiveness.     

Race,class, and emerging sexuality: teacher perceptions and sexual harassment in schools

Sexual harassment is a highly troubling gendered phenomenon that plagues young women on a daily basis. The way in which sexual harassment is perceived and treated is varied and is largely based on racial and class stereotypes. This paper highlights the findings from a study in which a group of middle and high school teachers were interviewed and their perceptions of sexual harassment on their campuses were discussed. What was revealed throughout this study was the way in which many teachers’ notions of sexuality are conceptualised through their notions of class and race. This paper addresses how such racial and class stereotypes veil the sexual victimisation of many young women.     

A learning model for enhancing the student's control in educational process using Web 2.0 personal learning environments

In recent educational literature, it has been observed that improving student's control has the potential of increasing his or her feeling of ownership, personal agency and activeness as means to maximize his or her educational achievement. While the main conceived goal for personal learning environments (PLEs) is to increase student's control by taking advantage of Web 2.0 tools and technologies, there is not a robust learning model available to achieve it. This contribution focuses on proposing a learning model built upon self‐regulated learning and student's control theories and concepts, and supported by the learning affordances of Web 2.0 tools and technologies for enhancing student's control by developing and applying Web 2.0 PLEs.     

Cognitive and metacognitive learning strategies among Arabic language students

This study investigates cognitive and metacognitive strategies in learning oral Arabic among students at Universiti Teknologi MARA (UiTM), Malaysia. The concept of these strategies was derived from the self-regulated learning framework, which consists of five components, namely rehearsal, elaboration, organization, critical thinking, and metacognitive strategies. The purposes of this study are to investigate the level of cognitive and metacognitive strategies used (1) among UiTM students; (2) between students with different prior experiences, namely, some of them had an experience of 5 years in learning Arabic in secondary school (abbreviated by SWE) and some of them did not have any experience at all (abbreviated by SNE); (3) between students of different gender; and (4) between students with the interaction of different gender and prior experience. The sample of this study consists of 183 students and employs a questionnaire adapted from the Motivated Strategies for Learning Questionnaire (MSLQ). The study revealed that (1) all UiTM students used cognitive and metacognitive strategies at a moderate level; (2) SWE scored significantly higher than SNE in all five components of cognitive and metacognitive strategies; (3) females scored significantly higher than males in rehearsal, organization, and metacognitive strategies; and (4) there were no statistically significant differences noted in all components between students with the interaction of prior experience and gender. This study had some classroom implications. It suggested that some improvement and changes in learning oral Arabic should be made in terms of selecting learning materials, implementing oral Arabic activities, and learning tasks, which will stimulate the use of all strategies, as well as conducting proficiency tests instead of achievement tests. Students should also be exposed to the learning techniques which used all these strategies extensively and collaborative activities may be carried out among students with mixed prior experience and gender.     

In Vitro Evaluation of the Efficacy of Liposomal and Pegylated Liposomal Hydroxyurea

Breast cancer is one of the most frequent cancer types within women population. Hydroxyurea (HU) is a chemotherapy compound for treatment of patients with cancer diagnosis, including breast cancer associated with several adverse effects. In this study, we applied nanotechnology to decreased drug side effects along with improvement of therapeutic index. Liposomation is widely used in modern pharmacological developments in order to enhance the effects of the drugs. To achieve this, in this study a mixture of phosphatidylcholine and cholesterol was made up and HU was added to the resultant mixture, was then pegylated using Polyethylene Glycol 2000 to increase resistance, applicability and solubility. The mean diameters of nanoliposomal and pegylated nanoliposomal HU were measured by Zeta sizer device and obtained about 402.5 and 338.2 nm. The efficiency of non-pegylated and pegylated liposomal HU was 70.8 and 64.2, respectively. Releasing HU in both formulations was estimated about 25.8 and 21.7 %. Also, this study investigated the cytotoxicity effect of nanoliposomal and pegylated nanoliposomal HU using MTT assay. Results of this investigation showed that the cytotoxic properties of pegylated HU was 3.6 % more than those non-pegylated form, while was 38.93 % more than ordinary from of HU. This study showed that the stability, releasing pattern and cytotoxicity of the pegylated nanoliposomal HU is better than that of nanoliposomal HU.     

Exploring the relationship between reading strategy use and multiple intelligences among successful L2 readers

Over the years, the multiple intelligences theory (MIT) proposed by Howard Gardner has renewed interest in learners’ use of effective learning strategies and produced interesting results. This MIT-oriented study investigated the role of successful L2 readers’ multiple intelligences in their effective use of reading strategies. To this end, a TOEFL reading comprehension test was administered to a cohort of 135 English as a foreign language students at several universities in the southwest and centre of Iran, and 80 students were identified as successful L2 readers based on the ETS rating scale and their TOEFL scores. Then, they answered an MI questionnaire originally developed by Armstrong and a reading strategies inventory adapted by Singhal. The data were quantitatively analysed using correlations and multiple regressions. The results revealed that linguistic, logical–mathematical and intrapersonal intelligences were the good L2 readers’ most dominant intelligences, while bodily intelligence was the least common type. In addition, they mostly employed metacognitive and cognitive strategies but rarely drew upon affective and compensation strategies while reading. Further, there was a significant positive relationship between linguistic, logical–mathematical, spatial, interpersonal, and intrapersonal intelligences and the use of metacognitive and cognitive reading strategies. Similar relationships were also found between linguistic intelligence and the participants’ use of memory strategy, on one hand, and between interpersonal intelligence and compensation and social strategy use, on the other. Importantly, linguistic and intrapersonal intelligences as well as metacognitive and cognitive strategy use were shown to be the best predictors of reading comprehension. Finally, the theoretical or pedagogical implications of the findings are discussed.     

Mathematics achievement in high- and low-achieving secondary schools

This paper identifies the amount of variance in mathematics achievement in high- and low-achieving schools that can be explained by school-level factors, while controlling for student-level factors. The data were obtained from 2679 Iranian eighth graders who participated in the 2007 Trends in International Mathematics and Science Study. Of the total sample, 1422 and 1257 students were from high- and low-achieving schools, respectively. Two-level hierarchical linear modelling was applied. The results indicated that of the total variance in mathematics achievement, 27.95 and 6.70% were due to between-school differences in the high- and low-achieving schools, respectively. Controlling for the school-level factors, the better-performing students were those with a higher level of confidence in learning mathematics in both samples. After controlling for the student-level factors, inadequacies in school resources and school type yielded the strongest link to achievement in the high- and low-achieving schools, respectively.     

The effects of cold application and modified PNF stretching techniques on hip joint flexibility in college males.

The purpose of the study was to determine the effects of modified Proprioceptive Neuromuscular Facilitation (PNF) flexibility techniques on hip flexion in college males and to determine if local cold application enhances the effectiveness of these techniques. Male subjects (N = 120), with an average age of 21.5 +/- 2.7 years, were randomly assigned to one of four different kinds of stretching treatments with cold or no cold application (15 per group). Range of motion (ROM) in degrees was determined following four stretching techniques: three modified PNF (PCP, 3-PIECP, 3-PIFCP) and a passive stretch (P). Data were analyzed using a 2 (conditions) x 4 (treatments) ANOVA. There were no significant differences in ROM between cold and no cold conditions. Significant differences existed among ROM techniques (p less than .05). Post hoc analyses revealed that the three modified PNF techniques resulted in greater ROM than the passive stretch technique. However, we conclude that cold application does not influence the effectiveness of selected stretching techniques.     

Sense of Challenge,Threat, Self-Efficacy,and Motivation of Students Learning in Virtual and Blended Courses

Feelings of threat, challenge, motivation, self-efficacy, and transactional distance reflect students’ struggles with the learning process. This study examined the relationship between students’ subjective feelings about the learning process in virtual and blended courses (VC and BC). This is a mixed-method study. The sample included 484 students from two academic institutions in Israel. The study found a connection between students’ subjective feelings about the learning process in VC and BC and feelings of threat/challenge, motivation, and self-efficacy. We found differences between students in different years of study and between those studying in various fields of study.
