Collection Strategies

This study had as main objective to analyze the perceptions of middle school students about the limits and possibilities of using the smartphone's stopwatch and video analysis, through the Tracker software, to explore the phenomenon of falling bodies. For that, a teaching sequence with six stages was proposed and developed in four classes of the 1st grade of High School. This is a qualitative research, of the participant type of research, whose data collection strategies were participant observation and the use of questionnaires. The emerging data were treated in the light of the Discursive Textual Analysis. As main results, it was possible to verify that the students recognized different ways of producing science, meant science as a human product, appropriated different ways of scientific language, recognized the limits and potentialities of the first method, the second and the association between Those.

Important Branch

The domain of motion or kinematics is important because it forms the basis of mechanics, an important branch of physics. By studying kinematic phenomena in the laboratory, high school students are likely to develop a better understanding of kinematics concepts as well as elements of the scientific approach to study natural and constructed phenomena. However, students encounter difficulties in understanding these concepts, just as in the acquisition of the skills necessary for the accomplishment of the different stages of an experimental process. Therefore, the purpose of this research was to provide guidance, according to a historical approach, which would inform teachers in the design of teaching sequences on the study of kinematics. Keywords: conceptual understanding, high school physics education, historical approach, kinematics.

Hiv Aids

Background: AIDS (Acquired Immunodeficiency Syndrome) is a collection of symptoms or diseases caused by a decrease in the immune system from the body due to infection from the HIV (Human Immunodeficiency Virus) which belongs to the retroviridae family. Teenagers themselves are vulnerable to HIV/AIDS. The right and precise knowledge of HIV and AIDS is important in HIV prevention efforts in adolescents. Method: This research is a descriptive research with cross-sectional design. The sample population of this study was grade XII senior high school students of the 2020/2021 at Methodist – 2 Medan by sampling total sampling. This study was analyzed univariately to look at the descriptive images. Result: From the results of this study, it has obtained that the knowledge level of students grade XII Methodist - 2 Medan had good knowledge about HIV / AIDS with the number of 144 people (70.6%). Conclusion: From this study, it was found that the level of knowledge about HIV/AIDS was mostly in a good category.

Balanced Diet

Introduction: Dietary trends such as consumption of lactose-free and gluten-free products or the use of alternative slimming diets are gaining increasing popularity, especially among young people. They determine their dietary choices, which are important from the point of view of human health. Unconventional diets are still considered as effective weight loss methods. The use of alternative diets may cause shortages of an essential nutrients, increase the risk of chronic non-communicable diseases and lead to the formation of incorrect eating habits. Balanced diet, in contrast to the alternative diet, takes into account the principles of rational nutrition and nutritional recommendations of the Institute of Food and Nutrition (IŻŻ). The aim: To investigate the influence of popular dietary trends on nutrition of high school adolescences. Material and methods: Subjects were adolescences in the age of 17-21 years attending high schools in Ruda Slaska (262 students, including 157 women and 105 men). Self-constructed questionnaire was applied in the study. Participation in the study was anonymous and voluntary. Results: In more than a half of young women (54,8%) and men (52,4%) the body mass deficiency was revealed (BMI<18 kg/m2). 33,6% of the respondents were on the non-balanced diets at least once in their lives. High school students knew gluten-free and lactose-free products but dietary trends, such as the consumption of gluten-free and lactose-free products, did not affect their diet. The main source of nutritional knowledge among respondents were their friends (78,2%). Conclusions: The results of the conducted research indicate the need to implement educational programs on the principles of proper nutrition. The increasing awareness of theyouth in this regard may contribute to reducing the interest in still popular alternative diets among young people and taking appropriate health behaviors by them.

Being Bullied

Although research on bullying has grown in scope in recent years, research specifically focused on gifted children’s experiences with bullying has been more limited. Studies of gifted children and bullying do exist, but the body of research in this specific area is not large. This article asserts that there are differences in the ways that gifted and nongifted middle school students communicate about bullying. This article examines quantitative differences in the ways middle school students who self-identify as gifted, and their peers who do not self-identify as gifted, disclose information about bullying. Data were collected from 343 middle school students at five different schools using the Olweus Bully/Victim Questionnaire. The study found that gifted students were more likely than general education students to disclose to their peers that they were being bullied but were not more likely than other children to communicate about bullying to their teachers or parents. These findings have important implications for schools and families as adults may underestimate bullying among the gifted. Additionally, these findings add to the literature supporting intervention programs that incorporate peer bystanders and add information to how we understand the importance of peers for gifted children.
