One of the use of learning media is to deliver the material from teacher to students. There are many types of learning media that can be applied to learning activities, especially at the primary school. In the era of technology, there are many new habits in life especially for primary school. Therefore, it is necessary to strengthen the material for primary school students about the value of goodness contained in regional arts. This research is included in research and development which will later obtain the results of a teaching material in the form of a Pop up book learning media by using Jombang's art figures. In addition to obtain a learning media, this research also aims to determine the process, implementation, and quality of the media. The research process was carried out in accordance with the steps in the 4-D model from Thiagarjan which had been modified by researchers without dissemination stage. In the development process, the researcher obtained 94.35% from material and media experts. While at the implementation stage, the researcher obtained 85.89% from the average score given by media users. Then 87.01% for the quality score which is the average of the process and implementation stages which indicates that the media developed by researchers is included in the category of very valid and feasible to be used without the need for improvement.

Do cell phones cause brain cancer? Does BPA threaten our health? How safe are certain dietary supplements, especially those containing exotic herbs or small amounts of toxic substances? Is the HPV vaccine safe? We depend on science and medicine as never before, yet there is widespread misinformation and confusion, amplified by the media, regarding what influences our health. In Getting Risk Right, Geoffrey C. Kabat shows how science works—and sometimes doesn't—and what separates these two very different outcomes. Kabat seeks to help us distinguish between claims that are supported by solid science and those that are the result of poorly designed or misinterpreted studies. By exploring different examples, he explains why certain risks are worth worrying about, while others are not. He emphasizes the variable quality of research in contested areas of health risks, as well as the professional, political, and methodological factors that can distort the research process. Drawing on recent systematic critiques of biomedical research and on insights from behavioral psychology, Getting Risk Right examines factors both internal and external to the science that can influence what results get attention and how questionable results can be used to support a particular narrative concerning an alleged public health threat. In this book, Kabat provides a much-needed antidote to what has been called “an epidemic of false claims.”

Abstract Objective One of the most challenging parts of running clinical trials is recruiting enough participants. Our objective was to determine which recruitment strategies were effective in reaching specific subgroups. Study design and setting We assessed the efficacy and costs of the recruitment strategies used in the Assessing Outcomes of Enhanced Chronic Disease Care Through Patient Education and a Value-based Formulary Study (ACCESS) in Alberta, Canada. Results Twenty percent of the study budget ($354,330 CAD) was spent on recruiting 4013 participants, giving an average cost per enrolled of $88 CAD. Pharmacies recruited the most participants (n = 1217), at a cost of $128/enrolled. ”Paid media” had the highest cost ($806/enrolled), whereas ”word of mouth” and ”unpaid media” had the lowest (~$3/enrolled). Participants enrolled from ”seniors outreach” had the lowest baseline quality of life and income, while participants from ”word of mouth” had the lowest educational attainment. Conclusion The ”health care providers” strategies were especially successful — at a moderate cost per enrolled. The "media" strategies were less effective, short lasting, and more costly. No strategy was singularly effective in recruiting our targeted groups, emphasizing the importance of utilizing a variety of strategies to reach recruitment goals.

<p class="06IsiAbstrak">DIGITAL UKBM DEVELOPMENT IN EXPONENT CONSIDER MATERIAL.<strong> </strong>The use of media and learning resources is part of the components that affect learning. Utilization and empowerment of UKBM to support learning is not only to improve the effectiveness and quality of learning, but more importantly is to increase the mastery of the material both teachers and students. One of the media that can be developed is an interactive learning module in the form of Digital UKBM. UKBM through multimedia can make the learning process more interesting, more interactive, able to convey historical messages through pictures and videos, encourage student learning through instrumentalia, be able to develop students' auditory senses or hearing, so that the material delivered is easier to understand. The purpose of this research is to design and build Digital UKBM on the material Inequality of Exponents in SMAN 2 Kudus and examine whether the application can facilitate the Teachers and Students in the learning process. This study uses a type of research development (Research and Development) with a model from Dick &amp; Carey. This research was conducted on 3 Mathematics Teacher class X MIPA and students of Class X MIPA 1 and 2 as many as 72 people in SMA Negeri 2 Kudus 2018/2019 Academic Year for 2 months starting from the preparation stage until writing the report. The results of the study, 85.00% of respondents stated strongly agree that the application of digital UKBM in learning can be said to be easy to do and will help teachers and students in learning.</p>

This study aims to: 1) determine the quality of the results of VCDs that have been developed, 2) find out whether there is an increase in student teaching skills in micro-learning. This research is a development research using ADDIE (Analysis, Design, Development, Implementation and Evaluation) models. Validation of learning videos is done by learning media experts and user response questionnaires. Data analysis used descriptive analysis and N-Gain test. The results showed that the average score of the media expert validation was 86.7% in the good and usable category, while the results of the user response questionnaire were 87.9% in the good category and suitable for use. Hail the N-gain test found that there was an increase in the basic teaching skills of students after using the VCD of basic teaching skills in the micro-learning course which was 0.7.
