The authors from Faculty of Science University of Hradec Králové prepared worksheets for teaching topic “The rainbow formation” in subject physics at high school through laboratory work, which combines classical experiment and computer model. Classical experiment can be done with tools commonly available in the school science lab. A computer model based on geometric and physical analysis of the problem is to create a table and graph through spreadsheet software. Carefully prepared worksheet was provided to several teachers at different types of high schools in Hradec Kralove and the surrounding area. Addressed teachers used the methodology and worksheets for certain groups of students. Efficiency of the method was tested by pre-test and post-test and evaluated with method of normalized gain. Each of the teachers gave both tests to experimental and control group. The results confirm the hypothesis that high school students who have completed experimental teaching of the topic of “The rainbow formation” understand optical phenomena better than students who did not pass this teaching. Keywords: physics, optics, refraction of light, geometry, rainbow formation, computer, spreadsheet.

Abstract In recent years, the prevalence of hookah smoking has increased worldwide, particularly in young people, which may have potentially serious consequences for their health. The aim of this study was to examine the factors associated with the consumption of hookah by high school students. The present study was conducted in the city of Novi Pazar, and students aged 17-19 years attending the following high schools were included: Medical School, Grammar School, Economic-Commerce School and Catering School. The study was designed as a case-control study. The cases were students who consumed nargile, while the control group consisted of students who had never smoked nargile. A special questionnaire was constructed for the purpose of this research, which was used to evaluate the opinions of adolescents on the consumption of nargile. Our research included a total of 270 seniors in high schools in Novi Pazar. The average age of the students was 18 years. The most important factors that may contribute to start using nargile were: previous consumption of nargile by older family members, divorced parents, and active smoking of cigarettes by other family members. Most students emphasized that hookah smoking is socially unacceptable form of behavior. Also, hookah smoker were neither more attractive nor popular. Nargile consumption is more common by adolescents whose parents are divorced, as well as by adolescents whose family members are smoking nargile or tobacco. The most common reason for nargile consumption among adolescents is a desire for relaxation.

Abstract: The aim of the present study was to investigate the effectiveness of study skills training on the qualitative academic achievement of girl high school students. This study was conducted by using an experimental design with pretest, posttest, and follow-up with the control group. The participants were 32 students from girl high school students of Tehran which were selected by cluster random sampling from girl high schools and then randomly assigned into control and experimental groups (Each group consisted of 16 students). The instruments used were Dortaj Qualitative Academic Achievement Questionnaire and Motevalli Study Skills Training Module. The experimental group received 8 sessions of psycho-educational group therapy and the control group did not receive any training. Two-way repeated-measures ANOVA was utilized for the analysis of data. Results revealed that there was a significant increase in qualitative academic achievement between pretest with post-test and follow-up among the experimental group. Moreover, there was a significant increase in qualitative academic achievement between post-test and follow-up in the experimental group with the control group. Additionally, the results showed that there is a significant increase in self-efficacy, planning, and motivation and also a significant decrease in emotional effects and lack of outcome control. In conclusion, the results of this study indicated that on the basis of deficit theory using learning and study skills training can lead to enhance student's skills to improve qualitative academic achievement. Further studies are required to examine whether exposing students to study skills training programs can lead them to enhance their qualitative academic achievement.   Keyword: Motivation Study Skills Training, Planning, Qualitative Academic Achievement, Self-efficacy.

Objective: The aim of this study was to examine the effects of nutrition education programme using the Convenient, Attractive, Normative (CAN) framework to facilitate changes in mindset, attitudes and behaviours towards food among high-school male baseball players. Design: Quasi-experimental design. Setting: Two public high schools in Osaka, Japan. Methods: Students in two high schools (mean age ±  SD, 16.6 ± .5 years) participated in the study. One school served as an intervention group ( n = 28) and received the CAN nutrition education programme. The other school served as a control group ( n = 22), and students within it did not receive the intervention. Students in the intervention group received three nutrition lecture sessions and face-to-face individual nutritional guidance over a 4 month intervention period. Before and after the intervention, all students were asked to record their food and beverage intake by taking food pictures, recording portion weights and sending these to the project dietitian. They were also asked to develop a dietary behaviour plan for meeting their goals. At the end of the intervention, they were asked about their experiences. Results: Students in the intervention improved their food intake, dietary balance and athletic performance. Bat swing speed was significantly faster following the intervention. Body weight increased without changing lean body mass in both groups. Conclusion: Results suggest that a CAN nutrition education programme may be effective in increasing motivation and promote dietary behaviour change among male adolescent athletes. Future interventions should examine these motivational processes and investigate the factors contributing to well-balanced meals.

This article intends to add to the rising discussion related to the employment of authentic plays and drama within a high school compulsory curriculum for enhancing learners’ foreign language (L2) oral skills. In particular, it examines the pedagogical use of authentic contemporary plays for developing learners’ L2 oral production in terms of (1) complexity – syntactic and mean length of AS-units (MLAS) and (2) accuracy – global and pronunciation accuracy. For this purpose, a class of 10 final year high school students with a lower-intermediate to upper-intermediate level of language in an Italian context was exposed longitudinally to a blended-drama approach – the use of literary play scripts, drama games and techniques, and a full-scale performance – conducted over two terms for a total of 40 hours in-class lessons. A control group was taught through a traditional approach over the same period. Quantitative data were collected through a pre-test/post-test design with three tasks under different conditions regarding status and interaction: oral proficiency interview (OPI), story-retelling and guided role-play (GRP). Findings revealed that drama significantly improved learners’ pronunciation accuracy, syntactic complexity and MLAS. There was no significant statistical result on global accuracy between the two groups. Pedagogical implications for teaching practice will be discussed.

This research aimed to see if learning by teaching (LBT) could really be implemented in classrooms. This case study intended to discover if LBT was applicable to teach tenses. This quantitative research involved 50 students from the two of 8th grade classes in one junior high school in Jakarta, one of which acted as the control group and the other one as the experimental group. This research focused on the learning of five tenses, namely the simple present tense, the simple past tense, the simple future tense, the simple present continuous tense, and the simple present perfect tense. A pre-test was employed before the research started and after the treatment had been given to the experimental group, a post-test was given a week after, and another post-test was given three months later. The results show that LBT helps the subjects learn better. Moreover, they also remember their materials longer. Therefore, LBT can be a good student-centered activity which has been proven successful.

This study aims to test the effectiveness of self-efficacy training to improve confidence in making career decisions (CDMSE) and achievement motivation (N-Ach) in 60 high school students. Through experimental approaches, obtained by 30 students as the experimental group and 30 students as a control group. Data were collected through questionnaires tests before and after the test, which is then analyzed by t-test. As the results of pre-test and post-test on a scale CDMSE test for the experimental group obtained probability value of 0.000 (p <0.05), which means that the hypothesis of no effect of self-efficacy training to CDMSE acceptable. so that self-efficacy training gives pangaruh to decision making career in high school students to determine the level of studies. And the results of the analysis of pre test and post test N-Ach-scale test in the experimental group obtained probability value of 0.000 (p <0.05), which means that in the experimental group there are differences in the results of pre-test to post-test. So the hypothesis that there is the influence of self-efficacy training to N-ach proven.
