Background:Although nutritional status of children and adolescents is of great concern various interventions and modifications aiming at promotion of healthy eating behaviors have limited impact due to insufficient understanding of dietary habits between different age groups and genders. The aim of this study in not only evaluation of nutritional knowledge, practice, and dietary habits of primary school and junior high school students in Isfahan province, but also this research explore crucial differences regarding gender and living area of the above-mentioned population in Iran.Methods:This cross-sectional study was conducted on 4700 primary school and junior high school pupils in Isfahan province. Data were collected through standard 24-h recall food frequency questionnaire and researcher-designed questionnaire. Independent t-test was applied for comparison of mean values of total units of consumed food materials. Qualitative variables were compared by using the Chi-square test. Data were analyzed by ACCESS 2010 and SPSS 18 software.Results:Nutritional knowledge of female pupils and junior high school students was higher than their male and elementary school students respectively; still, theses superiorities did not lead to higher practice score. Bread and cereals group received daily intakes in accordance with food and drug administration (FDA) recommendations. Indeed, vegetables, milk, and dairy products, as well as meat daily intakes, were lower than the FDA recommendation, whereas fats, oils, and sugars intakes were higher. In comparison to females, male participants had significantly lower consumption of vegetables and fruits whilst they had a higher intake of carbohydrates, fats, and meats.Conclusions:Our results showed that adolescents failed to meet sufficient nutritional requirements, and they had an imbalanced diet, which was considerably low in several essential nutrients and high in some food materials.
Introduction. The present study aims to predict students’ academic achievements based on the classroom climate, the mediating role of teacher-student interaction and academic motivation among Semnan University students. Materials and Methods. This study relied on correlation-and-description method of data collection. The sample population consisted of all undergraduate and postgraduate students at the Faculty of Engineering of Semnan University in the academic year of 2017–2018. Using a random stratified method, 200 subjects were selected as the sample (135 undergraduate and 65 master). Questionnaires of Patrick, Kaplan and Ryan’s classroom climate, Hernandez-Lopez’ teacher-student scale, Vallerand’s academic motivation questionnaire and Pace and Kuh’s student academic achievement scale were used. Reliability of the questionnaires was confirmed using Cronbach’s alpha test. Results. There is significant positive relationship between academic achievement and classroom climate, teacher-student interaction and academic motivation. Classroom climate has a direct and meaningful effect on students’ academic achievements. Also, the climate of the classroom by mediating the teacher-student interaction has indirect and significant effects on students’ academic achievements. Classroom climate by mediating educational motivation has an indirect and significant effect on students’ academic achievement. Discussion and Conclusion. The results of this study suggest the importance of openness to the classroom climate, interaction between teacher-student and academic motivation is to increase students’ academic achievements.
Background:Present study aimed to evaluate the prevalence of grades of nutritional status comprising underweight, normal weight, overweight, and obesity as well as other measurable anthropometric indicators of body mass index (BMI) in regard to gender, educational level, and living area among students settled in Isfahan province.Methods:This cross-sectional study was conducted on a sample of 4700 individuals (2349 females and 2351 males) being from 9 to 15 years old, while they were students of either primary school or junior high school. Random cluster method was applied in both urban (84%) and rural (16%) areas of Isfahan province. BMI values were measured and then categorized using reference growth charts from the Centers for Disease Control and Prevention (CDC 2000). Weight-for-age and stature-for-age indices were assessed as well in accordance with CDC growth charts.Results:The overall prevalence of underweight, overweight, and obesity was 13.9, 10.4, and 5.7%, respectively. Boys and students of urban areas showed a higher tendency of obesity and overweight in comparison with girls and rural students respectively. Furthermore, rural students had poorer status in both weight-for-age and stature-for-age indices. In addition, educational level was the only statistically efficacious factor.Conclusions:This study and previous ones demonstrated that children and adolescents’ nutritional status, which strongly affect general health status of individuals, should receive more exquisite attention.
This study examined Persian intermediate and advanced EFL learners’ perceptions regarding (a) their own and their teachers’ responsibility in learning language autonomously; (b) their decision making ability in learning language autonomously; and (c) their autonomous learning activities inside and outside the classroom. To this end, a questionnaire designed by Chan, Spratt, and Humphrey (2002) was distributed among 67 intermediate and 65 advanced EFL learners. Statistical analysis of students’ answers showed that overall, advanced learners tended to assume more responsibility for their own learning, to perceive themselves to be highly capable of autonomous learning, and to practice more autonomous learning activities compared to the intermediate learners. In addition, data collected through the interviews with some of the participants suggested that learners’ perceptions were greatly affected by their previous educational experiences. Since intermediate learners were not largely engaged in making decisions related to educational materials and activities used in their classrooms, they considered themselves as less responsible for and consequently less capable of choosing learning materials and activities. The findings of the study, along with the pedagogical implications, are discussed.
<div><p class="StyleABSTRAKenCambria">This study reports on a case study of a blind EFL learner. The purpose of the study was to explore a detailed situated data to examine to what extent it is feasible to be a successful language learner despite being visually impaired and lacking some learning resources. Interview data and the narratives of this EFL learner have revealed that her success was mainly based on her agentic interaction with the environment and learning context, her high motivation and strategic behavior, and her sustained efforts. The findings provide further insight into the role of learner in exerting control over contextual resources that frame learning and on how different factors interact with each other in the language learning process in the construction of learner identity and the strategies used by learners.</p></div>
