<p>Mathematics is important and applies to science, technology, society or the natural sciences. It is applied directly or indirectly. Most students find this to be a very stimulating, complex, and well-understood subject. Maths in high school is extremely important. The study was designed to investigate the impact of students' mathematical representation skills and their attitudes towards GeoGebra. This study was quasi-experimental and carried out on high school students. We have two groups belonging to the same standard class. The control group consisted of 22 students, while the experimental group consisted of 28 participants. The conventional approach was used to teach certain concepts of plane geometry to the students in the control group. On the other hand, the experimental group taught similar teachings using GeoGebra. The results show that students have more skills in mathematical representation using GeoGebra. The semi-empirical test also showed a significant change in students' attitudes between the pre-test and the post-test. Students are more active in mathematical representation skills in GeoGebra.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0967/a.php" alt="Hit counter" /></p>

INTRODUCTION: Low levels of hamstring flexibility may trigger certain acute and chronic pathologies and injuries. Poor flexibility is observed among teenagers and several authors have recommended the use of specific programs in this population to improve flexibility levels. The Pilates Method (PM) may be an appropriate intervention to achieve this purpose and has rarely been used with this population. Objective: Study was to assess changes in the flexibility of hamstrings after running a didactic PM unit for high-school students.METHODS: This research was developed through a quasi-experimental design. The sample consisted of 66 high-school students divided into experimental group (EG=39) and control group (CG=27). The intervention was carried out 2 times a week for six weeks. Each session lasted 55 minutes divided into three parts: warm-up, main part and cool down. Hamstring flexibility was assessed using the toe-touch test. Paired Student t-test and t-test for independent samples were applied. The size of the effect (d) was determined.RESULTS: The EG showed significant provident in hamstring flexibility (+3.54±3.9cm). The effect size was low (d>d>0,2<0,53), which means that a small proportion of participants improved their results. The control group did not have significant changes after the intervention. In the experimental group, both boys (+3.38± 3.7cm) and girls (+3.85 ± 4.2cm) showed significant improvements. The effect size was low for boys (d>d>0.2<0.53), which means that a small proportion of participants improved their results, and high for girls (d>1.15) which means that a large proportion of participants improved their results.CONCLUSION: This study showed that six-weeks of Pilates training in Physical Education classes has significantly improved the hamstrings flexibility among adolescents.

The purpose of this study is to explore the influence of introduction of the physical computing strategy of Arduino Boards in a program design course on coding literacy and the effectiveness of the application in technical high school students. This study selected two classes of twelfth-grade students enrolled in a program design course at a technical high school in Southern Taiwan as the samples. One class was the control group (43 students), and the other was the experimental group (42 students). During the 18-week course, the control group carried out a DBL (design-based learning) programming project, and the experimental group carried out the DBL programming project using the physical computing strategy of Arduino boards. Pre- and posttests and a questionnaire survey were carried out, while ANCOVA (analysis of covariance) was used for evaluation purposes. In the course, students in the experimental group were randomly selected for semi-structured interviews to understand their learning status and to perform qualitative analysis and summarization. This study proposed the physical computing strategy of Arduino boards, featuring staged teaching content, practical teaching activities, and real themes and problem-solving tasks. The results show that the coding literacy of students in the different teaching strategy groups was significantly improved. However, in the Arduino course on DBL programming, the students in the experimental group had a significantly higher learning efficiency in coding literacy than those in the control group. Moreover, according to the qualitative analysis using student interviews, Arduino boards were found to improve students’ motivation to learn coding and to aid in systematically guiding students toward improving their coding literacy by combining their learning with DBL theory. Thus, Arduino technology can be effectively used to improve students’ programming abilities and their operational thinking in practically applying programming theories.

The Difference

The misconception of the Solar System topic is still found in students so that it becomes one of the obstacles in the learning process. The purpose of this study is to analyze the effectiveness of the implementation of Predict-Observe-Explain-Apply (POEA) learning to change the junior high school students' conception in the Solar System topic. Quasi-experimental research with the non-equivalent control group design was conducted in one of the private junior high schools in Bandung city. Samples were selected based on the test of the average significance of the pretest score of the population. Furthermore, 30 students of the experimental class and 32 students of control class were selected. The research instrument, which consisted of 15 four-tier diagnostic test questions about Solar System were used to collect data before and after treatment. The tests were analyzed quantitatively by using the Mann-Whitney statistical test to determine the significance of the difference in the acceptable conception changes (Acceptable Change) of students in the experimental class with changes in the conception of students in the control class. The results of the research show that the implementation of POEA learning is significantly more effective than POE learning in changing the conception of Solar System topic. The findings of this study can be an alternative for junior high school teachers in planning learning about the Solar System, especially in an effort to change students' misconception about the Solar System.
