MOBILE PHONE DEPENDENCY AMONG HIGH SCHOOL STUDENTS IN RURAL AREA, CENTRAL JAVA

Introduction: The period of adolescence undergoes many physical and mental changes.Changing emotional and physical status along with increasing social, family, and academicpressure lead to various impairments in the mental health of adolescents. Academic failureleads to the suicide rate in adolescents, predominantly high during the declaration of examresults which is significantly high in a rural area in comparison with urban. The study examinedthe prevalence of academic stress among high school students in a rural area of Rolpa, Nepal. Methods: A descriptive cross-sectional study was conducted in 6 schools in Rolpa from July to October 2019. The sample size calculated was 521. A convenient sampling technique was used for this study.The target population was adolescents enrolled in high schools of Rolpa. Ethical approval was takenbefore data collection. The scale for assessing academic stress was used to find out the prevalence.A questionnaire was translated in local language and pre-testing was done in Nepal Police School,Sanga among 10% of the calculated sample size. Data entry was done in Statistical Package for theSocial Sciences version 18. Descriptive statistical analysis was done for prevalence calculation. Results: Out of a total of 521 students, the prevalence of academic stress was seen among 138 (26.5%)students at a 95% confidence interval (22.72-30.28). Conclusions: The prevalence of academic stress in our study was high and was consistent with otherSouth Asian studies. Understanding academic stress and providing help and support to the studentswould help ease the burden for them.

Test Instrument

The main analysis in developing assessment instruments is reliability and validity. A validity test is carried out to determine the appropriateness instrument that will be developed, both construction validity and content validity. The reliability test is to determine the level of consistency of the instrument that has been developed. This research was conducted to develop the HOTS ability to test items for high school students. The grid test instruments are arranged based on competence and HOTS indicators, which are then used to arrange items. The test instrument consisted of ten question items relating to the HOTS Thermodynamic Law problem, which included: 1) analyzing the magnitude of engine efficiency, work, heat, and internal energy changes, 2) evaluating Carnot's efficiency, and 3) creating a heat engine. The assessment of the instrument HOTS test obtained Aiken's V score in the range of 0.83 to 0.94, which is in the valid criteria. The validated instrument was piloted in 141 science grade XI student in High School 2 Batang, at Batang Regency, Central Java. The level difficulty of the Polytomous data was analyzed using the QUEST program for classical analysis and PARSCALE 4 for modern analytical theory based on the Partial Credit Model (PCM). The results of data analysis of the experimental items show that of the ten-question items, all are compatible with PCM. The reliability of the test instrument is 0.84, and the item difficulty level is in the range of 0.83 to 1.22. Information functions and Standard Error Measurement (SEM) indicate that test questions developed reliably to measure HOTS students' ability with an average category in -1.9 <θ <+1.7 logit scale with SEM ± 0.5.
