<p class="Abstract">Drawing – based modeling as learning approach, it allows students to create models based on drawing which help them to run a simulation. Students can use drawing–based modeling to learn a pair of interacting population known as predato–prey system while they usually conducted practicum using diagram of organisms. This study was to explore students’ argumentation and students’ understanding on the concept of the ecosystem. The study was conducted quasi – experimental using the matching – only post-test – only control group design. The participants consist of 60 grade 10 senior high school students in Subang, West Java. They are placed into two groups, 30 students in the experimental group and 30 students in the control group. Data was collected through argumentation test and selected response test for assessing students’ understanding. Students’ argumentation were analyzed using Toulmin’s argumentation pattern and statistical analysis. The result showed there is no significant difference between the experimental group and the control group for students’ argumentation. Most of the students are predominantly at level 2. But the coherency of arguments of the experimental group is more coherent than the control group. It means that the students in experimental group can make logical claim and supported by the correct and relevant grounds (data, warrant, and backing). The result of students’ understanding showed there is a significant mean score between the experimental group and the control group whether 72.33 for the experimental group and 62.13 for the control group</p>

This study deals with the second year senior high school students’ in reading comprehension. The objective of the study was the investigation of the effect of Panel Discussion on the students’ in reading comprehension. The study was designed in experimental research. The population of this study was the 2015/2016 grade X students of SMA Swasta Dharmawangsa Medan. The total number of population of the study was 415 students which consist of 12 classes. The sample of the research was 60 students. The technique used for obtaining the sample was the cluster sampling technique. The sample classes were divided into two groups, namely the experimental group that was taught by applying Panel Discussion Technique, and the control group that was taught by applying classical Technique. The instrument for collecting data used objective test. The data were taken by administering the pre-test and post-test to both of experimental and control groups. The test was taken and selected from the National Examination test items that were related to the kind of narrative text. So, the validity and reliability of the test items were considered valid and reliable. The data were statistically analyzed by using t-test formula at the level of significance α (0.05) = 1.669 with the degree of freedom (df) = 65. It was found that the t-observed was higher than t-table (t-observed = 4.93 > t-table = 1.669; α = 0.05). It means that Panel Discussion Technique significantly affect the students’ achievement in reading comprehension.  Keywords: Reading Comprehension, Cluster Sampling, Panel      Discussion.

This research has objective to investigate students’ listening comprehension through the use of podcast in EFL classroom. 60 high school students in Indonesia were taken as sample for this research with distribution of 30 students in experiment class and 30 students in control class. The samples were taken by using cluster random sampling. Quasi-experimental method with the post-test only control group design was applied in this research. In addition, a survey questionnaire was administered to experimental group to explore their perception on the use of podcast instruction in teaching listening. Findings revealed that there is a significant difference of post-test score between two groups, favoring experimental group. Data analysis using one way ANOVA showed significance value (sig. 0.010) is lower than &lt; 0.05 which interpreted that Podcast has significant impact on students’ listening comprehension. Additionally, the result of questionnaire indicated that students have positive attitude toward the use of podcast in listening classroom. Students perceived that podcasts provided authentic materials, interesting activities including listening exercises and meaningful tasks for them so they felt more motivated to learn English. This study recommended that teacher may utilize podcast in teaching listening considering its effectiveness as technology based learning tool.

This study aimed at investigating the effect of applying integrated Science, Technology, Engineering, Art, and Mathematics (STEAM) approach on motivation among students of grade 10 in a private school in Amman. In this context the researchers used a quasi-experimental method. The sample of this study involved 32 high school students; the individuals of the study were intentionally chosen and distributed randomly into two groups: the control group consisted of 19 students who studied Geography in a conventional way, and the experimental group consisted of 13 students who studied the same content using STEAM approach. To achieve the study goals, the researchers developed an instrument to measure motivation towards learning geography that focused on the following constructs of motivation: Internal Motivation, Grade Motivation, Class Anxiety, Career Motivation, Self-Efficacy, and Teacher Obedience. After verifying its validity and reliability, the instrument was applied on the study sample. The results of the analysis of covariance (ANCOVA) showed no significant difference on motivation in all of its constructs except for (Class Anxiety) which was in favor of the experimental group. The study recommended providing teachers with enough and valuable training opportunities on how to activate STEAM approach to ensure meaningful learning for students and to increase their awareness to future careers including STEAM jobs.

The purpose of this study is to explore the influence of introduction of the physical computing strategy of Arduino Boards in a program design course on coding literacy and the effectiveness of the application in technical high school students. This study selected two classes of twelfth-grade students enrolled in a program design course at a technical high school in Southern Taiwan as the samples. One class was the control group (43 students), and the other was the experimental group (42 students). During the 18-week course, the control group carried out a DBL (design-based learning) programming project, and the experimental group carried out the DBL programming project using the physical computing strategy of Arduino boards. Pre- and posttests and a questionnaire survey were carried out, while ANCOVA (analysis of covariance) was used for evaluation purposes. In the course, students in the experimental group were randomly selected for semi-structured interviews to understand their learning status and to perform qualitative analysis and summarization. This study proposed the physical computing strategy of Arduino boards, featuring staged teaching content, practical teaching activities, and real themes and problem-solving tasks. The results show that the coding literacy of students in the different teaching strategy groups was significantly improved. However, in the Arduino course on DBL programming, the students in the experimental group had a significantly higher learning efficiency in coding literacy than those in the control group. Moreover, according to the qualitative analysis using student interviews, Arduino boards were found to improve students’ motivation to learn coding and to aid in systematically guiding students toward improving their coding literacy by combining their learning with DBL theory. Thus, Arduino technology can be effectively used to improve students’ programming abilities and their operational thinking in practically applying programming theories.

Teenagers, who are considerably susceptible to smoking, must be educated to prevent smoking behavior that can cause health problems and even death. The aim of this study was to assess the effect of education through social media such as WhatsApp in the modification of smoking behaviors among senior high school students in Pangkep District, Indonesia. It employed a quasi-experimental, pretest-posttest-only control group design. The experimental group received education in the use of WhatsApp social media, while the control group was provided with leaflets. Data were collected through observation and interviews with a total of 180 students in both groups, with 90 students in each. Data analysis used a paired sample t-test and an independent sample t-test. The study suggested that disseminating health information through WhatsApp media about the dangers of teenage smoking was more effective than leaflets in changing student behavior.
