[Audio] . CHAPTER 1 Background of Study -This study focuses on the effect of 45 minutes class among Junior High school students. This study explores the benefits and bad effects of 45 minutes class to learning styles and Academic performance of student. -We want to study this to know the strategies of Junior High school students to cope up with this shorter time of classes. The rationale for considering this change stems from several potential advantages. Shorter class periods could potentially enhance student engagement by reducing the likelihood of boredom or disengagement. Furthermore, a more focused learning environment could lead to increased student attention and improved academic performance. Additionally, shorter periods might allow for greater flexibility in scheduling and curriculum design, potentially accommodating a wider range of learning activities and student needs. -But implementing this has containing a lot of concerns, including the potential for reduced instructional time, the need to adjust teaching strategies to accommodate shorter periods, and the potential disruption to existing schedules and routines. -Studies have presented data regarding the effects of short-term (weeks) and long-term (one year) use of standing desks in classrooms on children's health, cognition, and musculoskeletal symptoms. However, no previous study has examined such effects in an extremely short-term period such as one classroom lesson. This study aimed to examine the effects of using standing desks for 45 minutes on elementary school students' stress and executive function. For this experiment, 56 students were recruited from public elementary schools in Setagayaku, Tokyo, Japan. There were three conditions involving the use of standing desks (standing, sitting, and mixed), and all students performed tasks for 45 minutes in each condition. Measurements of stress and executive function were performed before and after the students engaged with each condition. Stress levels did not differ between the sitting and standing conditions for the full 45 minutes. The number of correct answers in the Stroop test, an interference task, was higher in the standing and mixed conditions (switching between standing and sitting). These results indicate that using standing desks for 45 minutes improved the 'inhibition' of executive function without excessively increasing stress levels.
