On the Application of Task-based Approach in English Listening Teaching at Middle Schools

In order to command a foreign language, it requires a balanced development in listening, speaking, reading and writing,which are four essential skills of language competence. Listening is not only a vital approach to acquire language, but also an important way to communicate with others in our daily life. The Task-based Approach(TBA) focuses on the specific task, which is the learning motivation. The process of finishing the task is the process of learning. The teaching result is judged by the task performed or not. This research discusses the application of TBA in English Listening Teaching at Middle Schools in order to improve the students listening ability. In the first part, the author introduces the background and significance of the research. In the second part, it states the definition of listening comprehension, the characteristics of listening process, three models of listening processing.

In the fourth part, discusses the current situation of English teaching at middle school,and the elaboration on the task-based model of English listening teaching. All in all, the research is to make the audience to understand the application of Task-based Approach in English listening teaching at middle schools so as to improve the students' English listening ability.

Developing a school-based drug prevention program to overcome barriers to effective program implementation: The CLIMATE schools: Alcohol module

Although effective school-based alcohol prevention programs do exist, the overall efficacy of these programs has been compromised by implementation failure. The CLIMATE Schools: Alcohol Module was developed to overcome some of the obstacles to high fidelity program implementation. This paper details this development of the CLIMATE Schools: Alcohol Module. The development involved two stages, both of which were considered essential. The first stage, involved reviewing the literature to ensure the program was based on the most effecttive pedagogy and health promotion practice and the second stage involved collaborating with teachers, students and specialists in the area of alcohol and other drugs, to ensure these goals were realised. The final CLIMATE Schools: Alcohol Module consists of computer-driven harm minimisation program which is based on a social influence approach. The program consists of six lessons, each with two components. The first component involves students completing an interactive computer-based program, with the second consisting of a variety of individual, small group and class-based activities. This program was developed to provide an innovative new platform for the delivery of drug education and has proven to be both feasible and effective in the school environment. The success of this program is considered to be testament to this collaborative development approach.

Evaluation of a School-Based Health Education Program for Urban Indigenous Young People in Australia

The aim of this study was to investigate the effectiveness of a school-based health promotion and education program in improving knowledge, attitudes, self-efficacy and behaviours of urban Indigenous young people regarding chronic disease and associated risk factors. A mixed methods approach was adopted for this evaluation;however, this paper will focus on the quantitative aspect of the study. The Deadly Choices? health education program was delivered weekly at six education facilities in Brisbane, Australia to participants from years seven to 12 over seven weeks. One school that received the Deadly Choices program the following term acted as the control group. Questionnaire data was collected immediately pre and post intervention to assess program impact. As self-reported by participants there were mostly significant improvements over time for questions relating to knowledge, attitudes and self-efficacy regarding leadership, chronic disease and risk factors within the intervention group. There were also significant changes within the intervention group regarding breakfast frequency (P = 0.002), physical activity frequency (P ≤ 0.001), fruit (P = 0.004) and vegetable (P ≤ 0.001) intake. Overall, there were few significant differences between the control and intervention groups regarding health attitudes and behaviours;however, there were considerably more improvements relating to self-efficacy and knowledge of chronic disease and associated risk factors between groups. The program also facilitated 30 Aboriginal and Torres Strait Islander health checks for participants. Deadly Choices is an innovative and comprehensive school-based program which has great potential to improve the health outcomes of Indigenous young people in urban areas by providing education in leadership and chronic disease prevention;engaging students in physical activity participation;and collaborating with health services to facilitate health checks.

Measuring Public School Competition from Private Schools: A Gravity-Based Index

This research develops a gravity-based index of public school competition from private schools within local markets. Proponents of educational reform often call for policies to increase competition between schools. A major hurdle for researchers examining this issue is to determine a workable definition of “competition” by which they can measure the degree of competition within local markets. This study addresses this challenge by developing a school competition index for public schools in the Jackson metropolitan area of Mississippi, USA that considers the enrollments in public schools and the enrollments in their neighboring private schools, as well as the distances between them. The school competition index reveals the degree of competition for each public school based on its spatial location relative to peer private schools operating within its service area. This methodology can be useful for evaluating competition in other markets and redefining the traditional market structure.

Evaluation of a Nutrition Intervention through a School-Based Food Garden to Improve Dietary Consumption, Habits and Practices in Children from the Third to Fifth Grade in Chile

Objective: Use a school-based food garden as an instrument to improve healthy dietary consumption, habits, and practices among children from the third to fifth grade in public schools in Chile. Design: Quasi-experimental, six-month intervention with an evaluation of dietary consumption, habits, and practices and use of the school-based food garden among the 3rd to 5th grade students. Setting: Two municipal schools in a low-middle income district in Santiago de Chile;one with a school garden intervention and a control school without a garden. Subjects: 155 third to fifth grade children, 63 in the intervention school and 92 in the control school (average age 10 years old, 58% boys). Results: In the intervened school, there was a significant improvement in the children’s dietary habits, such as peeling and slicing fruit (p < 0.05), making sandwiches (p < 0.05), and increased motivation to cook (p < 0.05). Fruit purchases at the school rose from 4% to 37% (p < 0.05) by the end of the intervention. Interest in growing vegetables or fruits at home increased from 48% to 70% (p < 0.05). The school children at the intervention school significantly increased their knowledge about 16 of 21 garden crops (p < 0.05), expanding the spectrum of the vegetables they can consume. There were no significant changes in the control school. Conclusions: The school-based food garden was effective in achieving change in dietary habits and practices among the third to fifth grade children. The project should be carried out for a longer period of time, so that the changes will be reflected in the students’ food consumption and nutritional status.

Improvements of Nutrition Behavior Fitness and Body Fatness with a Short-Term after School Intervention Program

The prevalence of childhood obesity has been increasing worldwide and lifestyle changes are the most important strategies in managing this prevalence. This study aimed to describe the intervention effects of nutrition and physical activities offered as an after school short-term on outcomes of healthy nutrition practices, fitness and lowering fatness. This quasi-experimental study was conducted with a convenience sample of 59 caucasian children, aged 7.7 ± 1.4 years old (52.5% girls) registered on a private school of a middle-size town located in Sao Paulo State, Brazil. The school-based 12-week intervention consisted of 2 weekly 60 minutes section, during 3 months, including a nutritional education and a physical activity curriculum. Anthropometric data was measured for all children at baseline and after 12 weeks. All parents were contacted and requested to complete questionnaire about child’s eating behavior at baseline and after the 12-week program. After the intervention, children showed an increasing in the intake of fruits (64.3%), vegetables (61.9%), and water (52.0%). Overall, 83.3% of the children changed eating behavior according to the questionnaire responded by the parents. Waist circumference was significantly lower and abdominal strength improved after participating in the intervention program. Mean height and weight were significantly higher in boys and girls after a 12-week intervention. Although mean values of BMI remained the same after the intervention it was observed a decreasing in the prevalence of obesity among the children. Thus our study showed that a school-based intervention program focused on nutritional education and physical activity program promoted waist circumference reduction and decreased obesity without affecting the height growth along with improved fitness and healthy eating behavior. This intervention program would be feasible and replicable in others schools around the country.

Biological Evaluation of New Schiff Bases: Synthesized from 4-Amino-3,5-dimethyl-1,2,4-triazole, Phenathroline and Bipyridine Dicarboxaldehydes

Four new Schiff bases with promising anticancer activity have been synthesized from 4-amino-3,5-dimethyl-1,2,4-triazole and di-pyridyl-aldehydes. Structures have been established by various spectroscopic methods. The compounds were tested in vitro to study their cytotoxicity and anti-oxidative activity in human lung carcinoma (A549), breast carcinoma (BT549), prostate adenocarcinoma (PC3) and mouse preadipocytes (3T3-L1) cells. Compound 1 was found to increase Glutathione (GSH) level slightly in all four cell lines. Compound 4 showed better selectivity and cytotoxicity against both BT549 and A549 cells compared to the anticancer drug tamoxifen. With the exception of compound 4 which reduced GSH levels in A549 and BT549, all other compounds maintained GSH levels in comparison to their respective controls.

Clinical surgery-oriented subject librarian services in medical colleges and schools

Regarding subject librarian services for clinical studies, researchers outside China have been focusing on subject service performance,evidence-based medicine, and comprehensive consulting services. In contrast, Chinese researchers have concentrated on service systems and methods but have not established mature systems and methods for clinical surgery-oriented services. Therefore,subject librarians in medical schools should become involved in clinical research and expand their perspective on medical library research. In addition, they should collaborate with clinicians to improve the overall level of research in hospitals while increasing the impact of subject librarian services in medical colleges and schools.
