SDGs aim to improve the quality of life from one generation to the next. One of the SDGs goals is quality education. One of the indicators that make up this goal is Mean Years School (MYS) In Indonesia, MYS is generated from Susenas. Susenas methodology is designed for the purposes of estimating macro indicators up to the district/city level, so the data from the Susenas cannot be used directly to estimate smaller areas/domains. In this study, MYS at the sub-district level will be estimated using SAE. SAE is a method that is often used to produce better precision in estimating a parameter in a small area, in this case a sub-district. SAE method used in this study is EBLUP. In SAE with the EBLUP based on the area level and using accompanying variables, it is able to provide a better estimation value than the direct estimation results. From the available samples, the adequacy of SAE precision can be determined by performing bootstrap resampling simulations at different sample sizes. Furthermore, an evaluation of the simulation has been carried out by looking at the goodness of the model and the comparison of the estimation results for each sample size. It found that even though the sample size was smaller than the Susenas sample, it could produce an estimated value that was almost the same as the entire Susenas sample size, besides that the R-Square value of the overall sample size also remained in the range of 40%.

Online learning has been applied all over the world during COVID-19 outbreak. Until today, that kind of learning has been about one and a half year conducted in schools. This paper wanted to reveal how joyful elements had been implemented on online learning during that time. Hence, we can learn some results which would show us how joyful elements should be implemented on online learning. Qualitative-descriptive method was used in this study. A questionnaire, which related to joyful elements on online learning, had been shared to 2nd semester college students of 2 departments (Natural Science and Physics Education) and 3 classes (A, B and C), but only 39 students sent back their answers. The students' answers based on their experience during online learning in this outbreak time. The data was processed and the result consisted of: 1) Jokes and appealing stories were the most effective online learning tactics (as a note, images and videos presentations had almost the same number of voters), 2) Learning in the form of assignments from teachers or lecturers were the most discouraged thing for them, 3) Oral lecturing was the most proper learning method for them, 4) Relaxed feeling because no need to attend formally in real classes was the most thing they liked. Based on the result, it was concluded that on online learning students need teachers' or lecturers' roles greater than when face-to-face learning in order to gain joyful elements during learning. Besides, students actually enjoy their houses as learning classes but hope that independent learning methods implementations (such as assignments) are reduced during learning. [ABSTRACT FROM AUTHOR]

Higher Order Thinking Skills (HOTS) is crucial for students to face the challenges of the 21st century. However, students' HOTS is often under-optimized. One alternative assessment that can be done by teachers or schools is to develop multiple choice questions. Multiple choice questions are questions that are often used in exams and other general tests. According to Well, Liu, & Garden (2018), it is necessary to present a more attractive assessment to be able to facilitate higher-order thinking skills in students. This study was to develop a complex multiple-choice test to empower students' HOTS when learning about the Excretion System. Characteristics of the question developed are multiple choice questions with stimulus and stem questions accompanied by 4 statements related to stimulus questions. Students are given the opportunity to analyze and evaluate appropriate stimuli and statements. In this process the student determines whether the statement presented is appropriate or not with the stimulus item. The participants were selected from Eleventh-grade students of SMA Kristen 1 Surakarta (Surakarta First Christian High School). The research was conducted in the first half (second semester) of the 2020/2021 Academic Year. Data were collected using the complex multiple-choice test. Data were analyzed using Anates V4 software. The results showed that of 25 questions, all have good validity, high reliability, and difficulty levels. The questions were 12% easy, 76% moderate-difficulty, and 12% high difficulty, have sufficient distinguishing power with minimal interpretation and have a good level of practicality. The results showed that complex multiple-choice questions were a suitable tool to empower higher-order thinking skills. [ABSTRACT FROM AUTHOR]
