This type of research and development aims to identify the need for digital math books, design digital math books, and measure the level of validity, practicality, and effectiveness of digital math books. The digital book development process refers to the ADDIE model, which includes five stages: analysis, design, development, implementation, and evaluation. This research was conducted at SMPN 5 Watansoppeng with the whole research subject to see the effectiveness of digital math books, 2 experts to get the validity of the digital math books developed, learning achievement tests in large group trials to see the effectiveness of digital books, and teacher response questionnaires to see the practicality of digital books. The results of the study show that the validation of material experts is in a good category and that media experts are in a very good category so that digital math books can be used in the learning process. The results of individual and small group trials by distributing questionnaires to each student's responses were in a good category, while in the large group trials by giving pretests and posttests, scores were in a significant category so that scores were obtained in the effective category. Then an analysis of the level of practicality was carried out by giving the value of the teacher's response to the mathematics subject teacher in the very good category so that a value was obtained in the practical category.

Until now, learning is still focused on thecognitive realm only. One aspect that is often neglected issocial attitudes, which are part of the affective aspect thathas an essential role in social life. The limited number ofresearchers who touch on this area makes referencesources of social attitudes still limited. This study is aSystematic Literature Review (SLR) using the PRISMAmodel. This model is considered a reasonablycomprehensive model because it has four main stages:identification, screening, eligibility, and inclusion.Researchers collected data from various open access datasources such as Google Scholar, Web of Science (WoS),Scopus, ERIC, Researchgate.net, Academia.com, andSciencedirect.com. Furthermore, the data were analyzedusing content analysis techniques in obtaining anoverview of trends and implications of research oneducation and learning social attitudes over the past tenyears. The results showed that there were only 14 articlesthat met the criteria for further analysis. The fourteenarticles discuss several main research topics, such as (1)improving students' social attitudes through learningmodels/approaches/methods, (2) learning social attitudesin the context of inclusive education, (3) developing andvalidating social attitude instruments, and so on other.These findings indicate the need for further and morecomprehensive research on learning social attitudes sothat this aspect is increasingly understood by variouselements of education as an aspect that is as important asthe cognitive aspect.

This research describes the results of try out the application of the school principal's recruitment system online. This application is a product of the principal's recruitment system that has been developed and will be implemented in South Sulawesi. This system is divided into two parts, namely administrative selection and academic selection. The research method is descriptive quantitative to describe the value of each variable as a result of the assessment of the subject of the study. Respondents in the study were 97 elementary and junior high school teachers in Jeneponto District who were interested in registering as school principals. The implementation of the research was from March to May 2018. The trial was started by giving instructions to the respondents on how to use the application. Furthermore, the respondent had the opportunity to register to the prospective school principals application. After the registration process, respondents filled out an assessment questionnaire on product quality with an assessment range between 1-5 for the five answer choices. Analysis of scoring data is useful for determining the category of results of respondents' assessment. The results showed that respondents rated this application as having very high quality.

Education aims to create individuals who are broad-minded, skilled, and have good morals. For this reason, moral education is seen as necessary as the primary foundation in shaping a generation so that it can become a global society in the current era of the industrial revolution 4.0. In achieving the goals of moral education, various strategies are needed in the classroom so that the results achieved are by what is expected. This research is quasi-experimental research using a one-group pretest-posttest design. This study aimed to determine the effect of the moral judgment learning model on the learning outcomes of high school students (SMA) as Generation Z with unique characteristics. The research instrument used in a learning outcome test to collect data on the pretest and posttest. Furthermore, the data collected was analyzed quantitatively using SPSS version 22 software to obtain descriptive statistics, pair sample correlations, and sample T-tests. The results showed a significant positive difference in the use of the moral judgment model on the learning outcomes of high school students as Generation Z from the pretest and posttest sessions.
