This research aims to investigate the effect of guided inquiry laboratory activity with video embedded on students’ understanding and students’ motivation in learning lights and optics topic. The method used in this research was pre-experiment. The sampling technique used in this research was convenience sampling, and the samples were taken from grade 8 in one of junior high school in Bandung. The sample was 20 students. The class implemented guided inquiry laboratory activity with video embedded in learning light and optics. The students’ understanding was measured using test given at pretest and post-test while students’ motivation was calculated using software ministeps (RASCH Model). The t-test paired sample also was performed on the average level of 95% to identify the significant difference of students’ understanding before and after the implementation of guided inquiry laboratory activity with video embedded. The results of this research show that the use of guided inquiry laboratory with video integrated gives an improvement of students understanding. Even though the value of n-gain is 0,264 (categorized as low level), the statistical test shows that there is a significant difference between students understanding before and after the implementation of guided inquiry laboratory activity with video embedded. There are 15 students from 20 students who are motivated in learning light and optics by using guided inquiry laboratory activity with video embedded. Students are motivated by the implementation of guided inquiry laboratory activity with video embedded.

The main objective of this study was to investigate the effect of using guided inquiry teaching method in improving grade eight students’ conceptual understanding of photosynthesis. The study employed Quasi-experimental research method. The data collection instruments were multiple choice tests, observation, as well as informal assessment. The pre-test and post-test were administered before and after treatment respectively. The informal assessment also administered before and after intervention. Besides, the observation was conducted from the first day up to the last day of the intervention. The pre-test and post-test data were analyzed using descriptive statistics and t-tests quantitatively while; data collected through informal assessment and observation were presented using narration. The finding of pre-test revealed that there was no significant difference between the mean score of the two groups. The post-test result revealed that experimental group students significantly improved their conceptual understanding of the topic photosynthesis compared to the control group students. The study concluded that guided inquiry teaching method is more effective than the lecture method in improving students’ conceptual understanding of photosynthesis. Based on the finding of this study, it was recommended that governments should encourage biology teachers to apply guided inquiry teaching method by providing appropriate instructional material.

Abstract: Changes to respiratory function due to regular aerobic exercise will affect the value of pulmonary function, especially in Forced Vital Capacity (FVC). This research aimed to determine the effect of aerobic exercise on FVC overweight male students of Unsrat Medical Faculty. This research is analytic with design experimental, one group pre and post test design. The sampling technique used is non-purposive sampling technique. The research sample was taken from the students of the Faculty of Medicine 2009, Univercity of Sam Ratulangi who fulfill the inclusion criteria. Some 32 students were selected as research subjects. After giving informed consent, FVC measurement was done with the spirometer. After it was measured, they were given treatmen in the form aerobic exercise using a stationary bike for three weeks with frequency of exercise three times a week and exercise intensity for 30 minutes. We measured again FVC values after the exercise three times program. Normality test data showed significance for FVC value before treatment by 0.752, and after treatment by 0.912. Comparison of the average value before and after exercise were tested by using a paired test. Significant value for FVC is P = 0.084, means there is no significant difference between FVC values before and after exercise (P> 0.05). The mean FVC was 3.88 before treatment and after treatment the mean value was 4.00, an increase in the average value of 0.11. Conclusion:Aerobic Exercise on a regular basis using a stationary bike on the overweight male student can improve lung function in particular the mean FVC but there was no significant difference from the mean value. Keywords: FVC, Aerobic Exercise, Overweight.   Abstrak: Perubahan fungsi pernapasan karena latihan aerobik secara teratur akan mempengaruhi nilai fungsi paru khususnya Forced Vital Capacity (FVC).

This study aimed to determine whether digital the use of folktales increases the vocabulary mastery of the seventh-year students of SMP Negeri 9 Buru. This research was a quantitative study by using experimental with a one-group pretest-posttest design. The samples consisted of 20 students from a total population of 320 students and were determined through a one-stage cluster sampling technique. Fiftyitems of multiple-choice tests were used to measure the vocabulary mastery of the students in the pre-test and post-test. The data obtained in this study were analyzed using descriptive statistics to determine the mean score and standard deviation between the pre-test and the post-test. A paired sample t-test through SPSS Version 20 was utilized to determine differences in the students' vocabulary mastery before and after receiving treatment. There is a significant difference between the mean scores in the pre-test and the post-test, namely (1.172 &lt;1.438), which indicates that there are differences in students' vocabulary mastery before and after treatment. The results of hypothesis testing proved that the value of t count = 7.528 is higher than t table = 2.093 (p = 0.05, df = 19). The comparison between the two values shows that the value of t count is greater than T table, which means that Ho: digital folktales does not improve vocabulary mastery of the seventh year students of SMP Negeri 9 Buru, is rejected, and H1: digital folktales increase vocabulary mastery of the seventh year students of SMP Negeri 9 Buru, is accepted. Therefore, it can be concluded that digital use of folktales improved the vocabulary mastery of the seventh-year students’ of SMP Negeri 9 Buru.

Adolescence is a phase of changeover from childhood to adulthood. For a girl, adolescence is a blend of physical and psychological preparation to enrol into a safe motherhood1. Menstruation is a basic female physiological process, capable of affecting the several other metabolisms within the body2. This study was conducted to Assess the Effect of Aerobic Exercises on Menstrual Difficulties among Adolescent Girls in a Selected School at Puducherry. Pre experimental one group pretest post-test design was used in this study. 60 adolescent girls who fulfilled the inclusion criteria were selected by Purposive sampling technique. On day one clinical variables and level of menstrual distress was assessed using Modified Moos Menstrual Distress Questionnaire with previous month experience. Aerobic Exercise session was started from 5th day of the cycle up to 22nd day weekly 3 days for 30minutes in a common room. Post test conducted using Modified Moos Menstrual Distress Questionnaire on the 5th day of the cycle the following month to assess the effectiveness of Aerobic Exercises. The study findings revealed that, the median difference in Menstrual Distress level between pretest and posttest with Aerobic Exercises intervention was observed to be highly statistically significant (p value<.0.001) Findings of the study revealed that there was highly statistically significant difference in the level of Menstrual Distress before and after Aerobic Exercises.
