The Relationship

Metacognition theory has been interested in research since the 70s of the twentieth century in the world. It can be seen that the thinking process, perception and metacognition of students and mathematical competence is one of the focus of research on mathematics education. However, the problem that is always interested by researchers in mathematics education is how to develop mathematical competence? What factors influence this capacity development process? How to support students to become better math problem solvers, especially in math? To find solutions to the problems posed above, a number of studies in the world and in Vietnam have focused on the relationship between metacognition and problem solving; At the same time, find ways to apply metacognition in the process of teaching mathematics. This study focuses on the goal of developing learners' competencies; Especially for the goal of developing mathematical competence for high school students through Mathematics, there is a need to research and exploit the thinking and cognitive factors in learning Mathematics to find solutions to overcome these problems.

The Relationship

The central dogma of molecular biology is key to understanding the relationship between genotype and phenotype, although it remains a challenging concept to teach and learn. We describe an activity sequence that engages high school students directly in modeling the major processes of protein synthesis using the major components of translation. Students use a simple system of codes to generate paper chains, allowing them to learn why codons are three nucleotides in length, the purpose of start and stop codons, the importance of the promoter region, and how to use the genetic code. Furthermore, students actively derive solutions to the problems that cells face during translation, make connections between genotype and phenotype, and begin to recognize the results of mutations. This introductory activity can be used as an interactive means to support students as they learn the details of translation and molecular genetics.

Primary Mathematics Education

Digital media is currently a trend in learning mathematics. However, digitalization of the media in primary mathematics education still at an introductory level. This study aims to determine students' mathematical literacy abilities, supported by digital media. The digital media used in this study was Virtual Mathematics Kits (VMK). This study involved 83 primary school students (45 intervention class; 28 non-intervention class) as participant of mathematical literacy training (6 weeks). Students' mathematical literacy evaluated by two section mathematical literacy test. This study revealed that mathematical literacy training led to improve mathematical literacy from both classes. However, mathematical literacy training with VMK aplication have better performance. This study shows that VMK as the digital media have big impact to support students' mathematical literacy abilities.

The purpose of this study is to find out how attitudes and interests of students and analyze the relationship between attitudes and student interest in high school physics subjects in Jambi Province. This type of research is quantitative which uses survey research design as a research procedure. This study involved 463 high school students in Jambi Province. The instrument used was a questionnaire with data analysis techniques namely descriptive statistics and inferential statistics. The results of the dominant student attitude indicators discussed in this paper are attitude indicators towards good research in physics with a percentage of 58.5% with a total of 271 students. The results of indicators of dominant interest are indicators of learning attention with categories good a percentage of 74.3% with total 344 students. The results of the analysis of the relationship between attitudes and interests of students towards high school physics subjects in Jambi Province showed r value 0.725 and positive. Therefore it is said that the attitudes and interests of high school students in Indonesia in physics subjects are high.

The Relationship

The aim of this study was to compare the relationship between physical education and sports high school students' positive thinking skill levels and attitudes of learning in terms of gender and years of doing sports. The study is a descriptive method, one of the quantitative research methods. The study group consisted of 280 (age: 20.98 ± 1.390) university students from School of Physical Education and Sports in Ordu university. As a result, it was concluded that the students' positive thinking skills were at a high level, and the nature of learning, anxiety, expectation, and openness to learning sub-dimensions of the attitude tolearning scale were at high levels. It was concluded that there is a statistically significant and positive relationship between the nature of learning, Expectation, and openness to learning, and positive thinking skill from sub-dimensions of the attitude to learning scale, but there is a negatively significant relationship between anxiety and positive thinking skills

The Relationship

The increasing use of smartphone among young people is creating negative effects and is an important public health problem in many countries. Smartphone abuse and addiction may cause physical and psychological disorders among users. However, the awarenes on this issue has been inadequate due to lacking of evidence. Objectives: To describe the current situation of smartphone using among students at highschools and universities in Hue city and to examine the relationship between smartphone using and sleep disturbances and psychological disstress among participants. Methods: A cross-sectional study with a randomly selected sample of 1,150 students at highschools and universities in Hue city. SAS-SV scale was used to evaluate phone addiction status, K10 scale was used for psychological distress assessment and PSQI scale was used to examine the sleep quality. Results: The proportion of students at highschools and universities having smartphones was 78.0%. The rate of smartphone addiction among high school students was 49.1% and that among university students was 43.7%. There was 57.3% of high school students had poor sleep quality, and that of university students was 51.6%. There was a statistically significant association between smartphone addiction and sleep disturbances and psychological disstress among participants (p <0.05). Conclusion: The prevalence of smartphone addiction among students at highschools and universities is alarming and is related to sleep disturbances and psychological disstress among participants. There is a strong call to develop intervention to help students to aware and manage the use of smartphone effectively.
