Abstract

The objectives of this study are to observe whether : (1) the improvement of students’ logical reasoning ability thought by TPS cooperative learning model is higher than those taught by expository learning model, (2) the improvement of students’ mathematical communication ability taught by TPS cooperative learning model is higher than those taught by exspository learning model, This study was held at SMP Negeri 24 Medan by having 56 students as sample. This study used quasi-experimental method with pretest-postest control group design. The population of this study was all students of grade VIII taking two classes (experimental 1 class and experimental 2 class) through random sampling technique. The instrument had required content validity and coefficient reliability. Data were anayzed by t test. Before it was used t test the normality and homogenity tests with significant level 5% had been done. The result of data analysis showed that the average of N-Gain logical reasoning ability test is 0,65 in experiment class, while 0,5 in control class, with sig = 0,007 and 0.007 < α 0,05. Therefore, the improvement of students’ logical reasonig ability taught by experiment class is higher than control class.  The average of N-Gain communication ability test in experiment is 0,62 in experiment class, while and 0,38 in control class, with sig = 0,000 and 0.000 < α 0,05. Therefore, the improvement of students’ communication ability taught by experiment class is higher than control class.

Abstract

This research aims to find out: (1) Differences in student learning outcomes taught using Camtasia media with conventional media; (2) Differences in student learning outcomes that have visual, auditory and kinesthetic learning styles taught by Camtasia media; and (3) Differences in student learning outcomes that have visual, auditory and kinesthetic learning styles that are learned with conventional media. The population in this study was grade V students of SD Negeri 060798 Medan Area, amounting to 82 students consisting of 3 classes. While the study sample is all 3 classes. The research instrument was in the form of a science learning outcomes test, and a learning style questionnaire. This research method is quasi-experimental hypothesis analysis technique t test; and analysis of variance. The results showed that: (1) Student learning outcomes taught with Media Camtasia 85.26 ± 5.45 (± SD) were higher than learning with conventional media 75.52 ± 5.86 (tcount = 8.147; p = 0.000); (2) There are differences in student learning outcomes that have visual, auditory and kinesthetic learning styles that are learned with Media Camtasia (Fcount = 24,964; p = 0,000); (5) there are differences in student learning outcomes that have visual, auditory and kinesthetic learning styles that are learned with Conventional media (Fcount = 6.770; p = 0.002).

Abstract

The rapid advancement of digital technology has led to a significant increase in smartphone use among early childhood populations, which may potentially influence social behavior development during the critical golden age. This study aimed to analyze the relationship between the duration of smartphone use and the social behavior of early childhood students at Aisyiyah Kindergarten, Ciputat–South Tangerang. This research employed a non-experimental quantitative design with a correlational approach. Data were collected using questionnaires. The study involved 48 respondents selected through a total sampling technique. The collected data were statistically analyzed using the Spearman rank correlation test. The results showed that most respondents were 4 years old (45.8%) and male (60.4%). The majority of children demonstrated low levels of social behavior (58.3%) and high levels of smartphone use duration (56.3%). Statistical analysis revealed a significant relationship between the duration of smartphone use and social behavior in early childhood (p-value = 0.000). Thus, it can be concluded that there is a significant association between smartphone use duration and the social behavior of early childhood students at Aisyiyah Kindergarten, Ciputat–South Tangerang.
