Blockchain and IoT Technology Transformation in Indonesian Education

Every area of life has been touched by technology, and the education industry is no different. Recently, there have been seismic shifts. Teachers and students used a blackboard technique in the traditional classroom teaching-learning process. But this process' characteristics have changed during the last few years. Technology has snuck in and significantly improved it. On the one hand, whereas in conventional classrooms the players were the teachers, the students, and the books, in the modern classroom the players are the teachers, the students, robots, the e-books, the laptops, and the books. With the help of e-lectures and tutorials, the teaching-learning process can now transcend geographical borders in classrooms. For the process, a vast amount of information is easily available. Additionally, the current situation shows a change from "Teacher-centered" to "Student Centric". However, the focus of this article is on utilizing the applications of Blockchain and IoT in the sector and identifying the areas where they prove to be advantageous. Several technologies have been major actors in modernizing the education industry. To comprehend and determine how these technologies offer a solution to significant educational difficulties, a thorough literature review must be conducted. The teaching and learning process needs to be understood in light of a variety of factors, including changes to the participants, the process itself, the results that are produced, and others. It is also necessary to identify the related difficulties. A thorough examination of these enables us to draw the conclusion that they can revolutionize education for the better in the future. Blockchain, in particular, is still relatively new, but because of the advantages it offers, further study and adoption will undoubtedly alter the teaching-learning process.

The Effectiveness of the Blackboard Technique in Integrating Saudi University ‎Students' English-Language Reading and Writing Skills ‎

هدفت الدراسة الحالية إلى قياس فعالية تقنية بلاك بورد في دمج مهارتي القراءة ‏والكتابة باللغة الإنجليزية لطلاب الجامعة السعوديين. اشتملت الدراسة على 40 ‏طالبًا وطالبة تم اختيارهم بطريقة عشوائية من جامعة القصيم. اعتمد التصميم ‏التجريبي على نظام المجموعة الواحدة. بعد تطبيق الاختبار القبلي, درست ‏المجموعة التجريبية باستخدام النموذج المقترح بالاعتماد على الاستراتيجية ‏المقترحة القائمة على استخدام تقنية بلاك بورد، والهادفة إلى دمج مهارتي القراءة ‏والكتابة, بعدها تم تطبيق الاختبار البعدي. وأوضح التحليل الإحصائي وجود ‏فروق دالة إحصائيًا بين متوسطات درجات الطلاب في التطبيقين القبلي والبعدي ‏للاختبار لصالح التطبيق البعدي. ولم توجد فروق دالة إحصائيًا بين متوسطات ‏البنين والبنات في المجموعة التجريبية في التطبيق البعدي للاختبار. ‏

Performance Evaluation using Blackboard Technique in Software Architecture

Validation of software systems is very useful at the primary stages of their development cycle. Evaluation of functional requirements is supported by clear and appropriate approaches, but there is no similar strategy for evaluation of non-functional requirements (such as performance). Whereas establishing the non-functional requirements have significant effect on success of software systems, therefore considerable necessities are needed for evaluation of non-functional requirements. Also, if the software performance has been specified based on performance models, may be evaluated at the primary stages of software development cycle. Therefore, modeling and evaluation of non-functional requirements in software architecture level, that are designed at the primary stages of software systems development cycle and prior to implementation, will be very effective. We propose an approach for evaluate the performance of software systems, based on black board technique in software architecture level. In this approach, at first, software architecture using blackboard technique is described by UML use case, activity and component diagrams. then UML model is transformed to an executable model based on timed colored petri nets(TCPN) Consequently, upon execution of an executive model and analysis of its results, non-functional requirements including performance (such as response time) may be evaluated in software architecture level.

Presentation of an executable model for evaluation of software architecture using blackboard technique and formal models

Considering the promotion and complexities of software systems and need to services for repair and updating, success of this system is extremely dependent to its architecture and design. Architectural techniques due to being used by the architectures frequently have specified effect on qualitative characteristics. If this effect is quantitative and measurable for each technique will enable the architect to have more care and convenience for evaluation of design and architectural designs. In this study, at first to show the structure and behavior of software architecture using blackboard technique, component diagram and unified modeling language activity diagram together with required data in relation to nonfunctional needs as stereotypes and labels were used. Later, upon converting the actual model to the formal model, requirements for system performance evaluation on the formal model is provided. Upon analyzing the results, it is observed that the offered method can evaluate the performance of software architecture based on blackboard technique at the design age.

How to Teach Mathematics: A Personal Perspective

`[A] professor will sometimes prepare for a lecture not by writing some notes or browsing through the book but by lounging in the coffee room with his colleagues and bemoaning (a) the shortcomings of the students, (b) the shortcomings of the text, and (c) that professors are overqualified to teach calculus. Fortified by this yoga, the professor will then proceed to his class and give a lecture ranging from dreary to arrogant to boring to calamitous...The good news is that it requires no more effort, no more preparation, and no more time to be a good teacher than to be a bad teacher. The proof is in this booklet.' ---from the Preface Lively and humorous, yet serious and sensible, this book is a practical guide to the teaching of mathematics. Eschewing generalities, Krantz emphasizes specifics---from how to deal with students who beg for extra points on an exam to mastering blackboard technique to how to use applications effectively. In addition, the book also deals with such sensitive subjects as cheating, bribery, and sexual harassment. Those teaching collegiate mathematics for the first time will find Krantz's advice especially helpful, and more experienced instructors will appreciate the book's elucidation of the fine points of excellent teaching. This book is intended for graduate students preparing for a career in college teaching of mathematics, mathematics instructors and professors.

A knowledge-based approach to the local area network design problem

Computer networks are an essential tool for people in business, industries, government, and schools. With the rapid rate of change in network technology and products, and the emergence of highly sophisticated network users, network design has become an increasingly complex task. Although the computer society aims at agreeing to a series of international standards for describing network architectures, the design of a computer network remains an ill-structured problem that lends itself perfectly to expert systems solutions. We propose an expert system that is able to design local area networks meeting the requirements specified by the user. Rules and guidelines pertaining to local area network design are formulated and incorporated into the knowledge base. The system is built on an object-oriented paradigm. The object-oriented approach and the hierarchical rule structure paradigm are discussed. We also employ the blackboard technique through which rules can access dynamic objects conveniently.
