O documento descreve uma pesquisa sobre o crescimento de grafeno em substratos dielétricos através de deposição química de vapor. O processo envolveu o aquecimento de filmes de cobre sobre diferentes substratos a 1000°C, resultando no crescimento de grafeno. Apesar de defeitos devido à alteração da morfologia do cobre e redepósito sobre o grafeno, os resultados indicaram que pequenos ajustes no processo podem levar ao crescimento de grafeno em larga escala para aplicações eletrônicas.

1. The document provides advisory comments from an associate professor for a student seminar group on their proposal.
2. The professor suggests focusing on proposal topics in Thai and English, proper reference and bibliography format, including an initial literature review source, and using textbooks and websites as resources.
3. An timeline is proposed where the group focuses on tools and data collection from September to December, then data analysis, discussion and an oral exam from January to March. The next appointment is scheduled for September 5th.
The document discusses key principles of media theory for instructional design. It outlines that the value of media in learning depends on how realistic the experiences feel and that concrete experiences aid abstract understanding. Learning increases with more audio and visual stimuli. Visual information is retained more than verbal information as it uses both visual and verbal memory. Media selection should consider learner and content characteristics. Foundational research discussed includes Skinner's work on reinforcement and Paivo's dual coding theory. Early contributors to the field are also noted.
The communication process involves the transmission of information from a source to a receiver through various channels that can be impacted by noise. Key components include the message, sender, receiver, channels, interpretation, and feedback. Different philosophical approaches view communication as transmission, behavior, interaction, or transaction. Early contributors to communication theory studied channels, noise, perception, and applied concepts of culture and message design to instructional design. Related concepts that have been researched in instructional design contexts include cognitive load, cueing techniques, attention, message structure, and multimedia design principles. Communication theory is relevant to many instructional design domains including learners, content, strategies, media, and the design process.
The document discusses technology in learning and teaching in Thailand. It provides context on national ICT policies and initiatives like SchoolNet, which aims to connect schools to the internet and share educational resources. Key points include:
1) Thailand developed national ICT plans and policies to promote technology integration and develop e-society, e-education, and other sectors.
2) Initiatives like SchoolNet connected schools to the internet and each other to build online communities and share information and resources.
3) Issues remain around infrastructure, connectivity, costs, and technical support for using technology effectively in education across Thailand.
The document discusses technology in learning and teaching, including:
1) Information and communications technologies (ICT) are becoming integrated into education to support teaching, learning, and administration.
2) Thailand has implemented a national ICT plan to promote ICT development and utilization, including connecting schools to form the SchoolNet network.
3) Literacy is now defined more broadly as "multiliteracy" due to the diverse communication modes enabled by new technologies, requiring students to develop functional, academic, critical, and electronic skills.
The document discusses the history and evolution of computer-assisted language learning (CALL) from the 1960s to present. It describes three main stages: behavioristic CALL in the 1960-70s using drills and practice; communicative CALL in the late 1970s-1980s focusing on communication; and integrative CALL currently, which seeks to fully integrate technology into the language learning process. It also discusses the changing roles of teachers from being the sole information source to facilitators of learning.
