Insight Into

A study was conducted to inspect conceptual understanding of solubility concepts among first-grade students and to identify the potentially present misconceptions. A total of 122 high-school students (15–16 years old) were involved in the study and a solubility concept test was administered in order to get insight into their conceptual knowledge. Students were divided into two groups: control group and an experimental one. Only the experimental group was subjected to a conceptual change intervention program.Descriptive statistics and significance testing were used to analyse and summarize data. Independent-samples t-test was used to test the differences in the scores between the control group and the experimental one and between male and female students involved in the study. For multiple-choice questions, four areas of conceptual understanding have been set: satisfactory conceptual understanding, roughly adequate performance, inadequate performance and quite inadequate performance. Furthermore, the findings revealed six misconceptions present in students’ minds.

The purpose of this study is to find out the contribution of games in improving grammar acquisition of the Yoannes Junior High School students. In teaching Grammar, teachers should apply the appropriate technique and method. In this study, games are chosen to be used.  Participants are divided into treatment group, the experimental group and the control group. The experimental group is taught by using games and the control group is taught by using the memorizing method. Each group is assigned to do the same test, containing sections which involved grammar items. They attended the course, once a week for eight weeks. Each meeting lasted forty five minutes. The material is taken from textbook that applied at school. Pre- test is given before the experiment and post- test is held immediately after the experiment is over. The Null hypothesis of no significant differences are constructed and tested, and then one- tailed T- test is used to compare the score of the games and memorizing groups and to analyze the hypothesis. The alpha level is set. Teaching the arbitrary rules of grammar to students who cannot speak, understand of use the English language is an absolute waste of time, effort and money and is downright foolish. The practice is about as rational as teaching advanced race car skid control to someone who does not know how to drive. In English conversation, get them talking, get them comfortable using the language, then teach them by using rules of grammar once they understand the language.

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.

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.

Dance sport, like other sports belongs to the aesthetic and coordinating sports; with high demands of nearly all motoric skills. They require mainly the ability to coordinate, which is often the limiting factor of performance in dance sport. Due to the fact that dance is synonymous with music and closely associated with the rhythmic capabilities, we will focus further on detailed characteristics of the two rhythmic abilities: rhythmic perception and rhythmic execution. The research sample consisted of 153 test subjects in the age range 17-34 years. The experimental group consists of 104 dancers (53 women and 51 men). The control group consisted of 49 high school students. To examine the level of rhythmic perception, we used a test called rhythmic discrimination. To examine the level of rhythmic execution, we used a test called rhythmic drumming. We proved that dance sport has a positive effect on the level of our selected rhythmic ability, the longer the subjects danced, the better the results achieved in tests. We were unable to prove a statistically significant relationship between rhythmic perception and implementation.
