In this case study, a professor was observed to investigate use of instructional examples when teaching the Intermediate Value Theorem in a calculus course. Video-recorded lessons were analyzed with constant comparison to video-stimulated recall interviews and field notes. The professor employed multiple instructional examples, which was initiated by students and modified by the professor. The professor asked students to build non-existing examples as an informal proof of the Intermediate Value Theorem and assessment of students' previous knowledge. Use of incorrect examples on instructional purpose can be an appropriate way for formative assessment as well as a bridge between informal and formal proofs in college mathematics.

This paper aims to introduce some useful multimedia freewares, and also support Chinese instructor with discussing how to operate them for instructional design of multimedia language learning class. For this aims, this paper consists of three parts: First, instructional design. This part is focused to what kind of instructional model to be based on, for example, Dick & Carey model, ADDIE model, ASSURE model etc. This part introduces these models, and modifies ADDIE and ASSURE model to D.D.A.I.E.S and S.S.A.U.R.E.S as 'A(nalysis)' in these model may apply to the next 'D(evelopment)' on ADDIE, 'S(elect Methods, Media and Materials)' on ASSURE in the practical Chinese class. Second, Programme: What to use. This part is focused to what kind of free software we can use. In the web site online, there are huge free softwares so we usually hesitate to select and also don't know how to operate even though selected one of them. This part, accordingly, introduces ten of useful freewares and compares each other in terms of usefulness for Chinese instructors. Third, Programme: How to use. It is of no use just to know what to use but not to know how to operate, so this part describes how to use freewares like a kind of manual in detail as far as possible. In conclusion, we hope more Chinese instructors to learn and use more useful freewares for designing the better multimedia Chinese class by this paper.

This paper detailed the content and methods of the instructional activities of teacher-librarians in Korea. Using Kuhlthau's levels of education model as a theoretical framework, the study analyzed its data on the direct instructional activities the Korean teacher-librarians reported. The participants included four researchers in school libraries as well as the high school teacher-librarians in Seoul. Written survey were conducted for researchers and teacher-librarians respectively. The results show that there exists a gap between the theoretical emphasis on instructional activities of teacher-librarians and the practice of teacher -librarians in schools, and that the level of instructional activities has not yet advanced fully to the high levels of instructional activities. Future efforts should be made on developing legal as well as educational systems to support advancing the instructional levels of teacher-librarians. Integrating information literacy curricula into the national-level curriculum for public education could be a good example.

This paper investigates instructional strategies with potential for improving students' achievement in word problem solving. This review compares and analyzes the direct instruction (DI) and cognitively guided instruction (CGI) research on K-3 word problem solving mathematics students in a demonstration of my position that teachers need to understand student mathematical thinking to enhance students' achievement in word problem solving. CGI provides a more appropriate instructional model than DI for teaching word problem solving. For example, student-centered, conceptual understanding, and children's informal or invented problem solving strategies communicating with each other mathematically, etc. Korean teachers and teacher educators need to consider implementing CGI teaching strategies.

Classroom observation instruments are often used to evaluate teachers' instructional practices and provide feedback to inform interventions or research studies, or professional development efforts. While designed as research tools, many classroom observation instruments can provide important information to support teachers' learning and instructional change by providing a focus for formative assessment or self-evaluation of practice. In this paper, we review two classroom observation tools and the protocols for their use with an implementation example for one of the tools. These tools are more foreign to the field compared to others but have features that might serve as affordances in relation to the purposes of a specific investigation.

The primary goal of this study was to suggest the ways of developing various types of instructional models which could be effectively used for science lessons in secondary schools. In order to attain this goal this study used literature review as its main method. This study was carried out through the process of three steps as follows: The conceptual relationship among instruction. teaching, and learning was examined. Then the general instructional models built on the traditional epistemology and psychology were reviewed and analyzed in terms of their characteristics and limits. The nature of instructional models developed for science education in secondary schools were analyzed The essential features and limits of the models were discussed in relation to their theoretical background and applicabilities to actual practices of science education. The implications for science learning were drawn from modem philosophy of science, which were used for developing instructional model. The strategies for using the new instructional model was also suggested. One general model of science instruction was given as an example applicable for science classrooms. The model was composed of appropriate teaching strategies and processes.

This study investigated university students' perspectives on good class and instructional practices through social network analysis. The subjects were 321 students in the third and fourth academic years in a Korean university. The subjects completed four open-ended questions, asking about experience of good class, good instructors' teaching practice, and their feelings and attitudes when participating in good class. As social network analysis, KrKwic (Korea Key Words in Context) was used to compute word frequencies and analyze semantic network structures and Ucinet Netdraw to assess centrality in the social network, consisting of degree centrality, closeness centrality, and between centrality. The results are as follows. First, students showed 5 keywords to depict what good class is, including 'understanding', 'example', 'video', 'interest', and 'communication'. Second, the characteristics of teaching methods by professors who practice good class indicate 'assignments', 'questions', 'understanding', 'example', and 'feedback'. Third, the top 5 keywords of students' attitudes as participating in good class are 'active', 'participation', 'focus', 'listening', and 'asking'. Last, keywords depicting desirable class that students most wanted to take next time are 'assignments', 'rewards', 'understanding', 'difficulty', and 'interest'. The findings from this study include the meanings of the semantic network structures of words in the text making up messages. Also this study can provide empirical evidence for educators and educational practitioners in higher education to create effective learning environments.

The instructional consulting has emerged as an important teaching development program in university. So, this research aims to analyze the instructional consultation system in centers for teaching and learning in four-year-course universities and deduce implications from it. To this end, focusing on instruction consulting program types, status, and example cases for promotion, homepages were reviewed and phone interview was conducted from July to August, 2015. The results were as follows. First, 9 types of instruction consulting system in universities were found. Second, the status of offering the programs and implementing them did not correspond to each other. Third, universities were mainly using in-school consultants. Fourth, universities had various ways of using the results and reward systems. Lastly, as for the example cases, through various consulting programs, consultant pools, use of results and reward system, and connection with other programs, it was found that instruction consulting system was operated organically. The implications that the research result offers are as follows. First, there should be accurate diagnosis of instructors and customized consulting systems based on needs. Second, there should be supports inside schools and cooperation between external organizations that can help raise consulting teams of various backgrounds. Third, the instructional consulting should be made through joint considerations and reflections of instructors. Fourth, universities should provide systematical support for instructional consultation and have higher awareness about it.

The Interdisciplinary-Multistrategic Science Education Program(IMSEP) is designed as an efficient program for the education of the gifted in science. An example of the contents is developed, which encompasses mathematics, physics, chemistry, astronomy, and biology. In the program, the complexity(interdisicplinarity) of scientific contents and instructional strategies used to deliver the scientific contents are designed to be correlated to each other in such a way that as the scientific contents gets more complex, the scientific skill to be taught by the instructional strategy becomes deeper. Through the careful balance between the scientific contents and the instructional strategies student's scientific knowledge and scientific skill will develop balanced and the effectiveness of science education will be maximized.
