The paper offers a few activities for high school students which use the magnetometer of a smartphone to measure the value of magnetic fields. The first part of the paper deals with finding the magnetometer of the used smartphone. Following is the first selection of activities which are focused on discovering the equation for measuring the magnetic field of coil with a negligible length, while the second selection of activities use the discovered equation to measure the permeability of vacuum and finally to measure the magnetic field of the earth. Sample results of the experiments are given, showing the accuracy and effectiveness of the conducted experiments. The activities offer teachers a novel way for teaching the equation for calculating the magnetic field of a coil, as well as measuring the permeability of vacuum in a classroom environment.

The Magnetic Field

The following article has been written primarily by the high school students who make up the team “Cryptic Ontics”, one of the two winning teams in the 2018 edition of CERN’s Beamline for Schools (BL4S) competition, and is based on the set of experiments the students endeavoured to conduct over the course of a two-week period at CERN. Reconstructing influential physical theories from scratch often helps in uncovering hitherto unknown logical connections and eliciting instructive empirical checkpoints within said theory. With this in mind, in the following article, a top-down reconstruction (beginning with the experimental observations and ending at the theoretical framework) of the Lorentz force equation is performed, and potentially interesting questions which come up are explored. In its most common form, the equation is written out as: [Formula: see text]. Only the term that includes the magnetic field [Formula: see text] will be dealt with for this article. The independent parameters we use are (i) the momenta of the particles, (ii) the charge (rather, the types) of particles, either positive or negative, and (iii) the current passing through the dipole generating the electromagnetic field. We then measure the angle by which particles get deflected while varying these three parameters and derive an empirical relationship between them.

Selection Of

The likelihood that learned skills will be maintained in natural performance settings may be affected by the number of opportunities to perform the skills following acquisition. To examine this hypothesis, 17 high school students with moderate to severe mental retardation were selected from three public school classrooms. Each student had learned one adaptive skill that he or she had performed at least twice per month without additional training for 5 months prior to this study (high opportunity). Each student had also learned one adaptive skill that he or she had not performed more often than once per month over the 5 months immediately preceding the study (low opportunity). Performance of both behaviors was probed under conditions as similar as possible to those experienced during training. Twelve of the 17 high opportunity skills were performed successfully while only 4 of the 17 low opportunity skills were completed. A sign test indicated these differences to be statistically significant. Implications of the results for selection of IEP goals and the inclusion of “opportunity” objectives are discussed.

This is a study of high school students’ attitudes toward the English language in Lebanon. The purpose of this research is to assess the extent of use of English inside and outside the schools taking into consideration the attitude towards the language. Two schools were selected, one upper middle class and one lower middle class. This selection of different social classes aims at finding whether a student’s socio- economical background affects his/ her attitude toward the English language. The sample of respondents returned 52 questionnaires from the two schools. Although this sample was a modest one, it highlighted the differences in attitudes towards the English language, but these attitudes did not relate much to the socioeconomic class as much as personal preferences. However, what was salient in this research is how students from the lower middle class were more inclined to use English to raise their social status and both groups agreed that English is essential to their progress in life.

Anak Pelangi Indonesia (API) Foundation is a non-profit foundation that offers scholarship programs for elementary, middle and high school students. This institute is supported by donaturs who give contribution to the Foundation. The donation is processed to be a cost that is used to pay Sumbangan Pembinaan Pendidikan (SPP) or Education Development Donation of each student. Currently, the provision of monthly donor fund is at uncertain amount so that the Foundation needs to determine the students of whom SPP will be firstly paid. However, the funding needs of each student are different due to the different amount of SPP and a giving fine from the school for the tardiness in paying the tuition. From these matters, the Foundation finds it difficult in deciding which students whose the tuition will be paid first. The solution to this problem is to use the four criteria referring to the tuition payment, namely the difference of pay date, fine, rank, and the amount of payment. The four criteria is then given the same integrity which is 25% for each criteria and counted by using Weighted Product (WP) method. The result of this research is an information system to the selection of scholarship payment using Weight Product method that takes the biggest value from the calculation result as a reference in deciding which students of whom SPP will be initially paid in accordance with the current fund condition.

A prevalent goal of education in schools is reading comprehension enhancement. Therefore, a critical issue in   educational psychology is investigating the factors contributing to increase the reading achievement including both classroom climate and self-determination. This study explored the relationships of Iranian High School students’ self-determination and classroom climate with their reading achievement.  150 Iranian (male and female) students from Sama and Fazele high schools in Mashhad were selected through convenience sampling. The instruments were IOWA self-determination, Classroom Climate Questionnaires, and a validated researcher-made test. It was a type of quantitative and correlational research. Results revealed a significant and positive relationship between self-determination and reading ability. They also showed that among the six subscales of the self-determination, financial management had a significant relationship with the reading achievement scores of students. However, the emotional independence of peers had a negative correlation with the reading achievement scores of students. The results showed that teachers’ skill in orienting tasks can enhance reading achievement score and make the classroom climate more motivating. This study has potentially helpful implications for English language teachers, English institutes, and students. Teachers can enhance student’s self-determination by providing a friendly classroom environment and indirectly boost the students’ reading score.

Various types of educational devices that are used as a support for the creation of a good education are certainly important. One of them is using an effective method to provide a concept to students optimally. This study aims to analyze how high and important the influence of the experimental method on science subjects at the junior high school. The method used is a qualitative research method with a mini survey method on 47 samples consisting of junior high school students, high school students, college students, and alumni students as well as a literature study method (library study) which is carried out by screening electronic books (e-books) and e- journals. The results showed that 94% of experimental research methods were effectively used and 6% were not effectively used in the science learning process. The effectiveness of this method is that students can prove that an accepted concept is in accordance with the given theory and students can hone their psychomotor abilities. The weakness of this method is that it can be seen from the inadequate infrastructure, the ability of teachers, controlling students, and the selection of practicum materials.

Since Gardner introduced the importance of motivation on Language 2 learning, the concept has been accompanied with three more relevant concepts; amotivation, demotivation and remotivation. This paper mainly focused on high school students’ de-motivation and remotivation in English. De-motivation is a set of factors which decreases the motivation level of the learners and re-motivation is an attempt to overcome those de-motivating factors. English learning-teaching process has been a problematic issue for a long time in Turkey. While there are researches focusing on the de-motivating factors in many countries, such a research for Turkish high school students has not been found. This research aimed to fill this research gap and to determine the English demotivation level of the students and the demotivating factors for them and to put forth suggestions to re-motivate the learners. An explanatory design was used as a mixed method research design. The sample was constituted of 579 students. Research results revealed that demotivation level of high school students in English is quite high, their motivation decreases most in high school period. Lack of interest in English, attitude of course teacher, classroom environment and course materials are among demotivating factors. In addition, the students request that, for remotivation, courses should be entertaining, technological tools should be utilized more and frequency of speaking activities should be increased.
