Considerable efforts have been attempted to identify what makes high-quality mathematics instruction, including diversity and variability across different educational systems and cultural contexts. As the instructional elements related to effective mathematics teaching can be commonly applied to different content domains, they may be efficient in selecting such teaching. However, such elements may not reflect on the specific but essential features of each domain. This paper compared and contrasted two sets of measurement teaching practices, which were recognized as good instruction, in terms of how the key elements of measurement domain were implemented. As such this paper is expected to accumulate significant knowledge about elements of effective mathematics instruction that are specialized in a particular content domain of measurement. This paper suggests that domain-specific approach be considered in studying good mathematics teaching.

In this paper, we aim to draw up an alternative instruction scheme by designing a web based instruction model on mathematics. Some learning materials are developed according to the scheme, and its educational effects are examined when it is committed to through regular curriculum. The study is composed of three major parts; setting of the theoretical foundation on cultivating Web based educational materials, design and composition of Web based teaching-learning model, and its experiments in the regular class. First of all, we are concerned with the core principles on WBI including the learning theories, developing learner oriented instruction model, design as well as build-up process for education materials, and strategy in instruction. Next, we propose an alternative instruction model for mathematics, in which programs to embody mathematics education and instruction on the Web are constructed, on the while, the study is proceeded through the Web Site. Finally, we design and produce a WBI instruction model on the subject of the plane quadratic curves. This model is examined in the regular class to estimate its educational effects compared with traditional teaching standpoints. Concomitantly, we explore essential elements and the direction of future growth associated with the Web oriented education.

The purpose of this study is to investigate the effects of portfolio instruction on the creativity and scientific inquiry ability of 6th-grade students in science classroom. Four classes were sampled from an urban elementary school in southern part of Seoul. Two classes were assigned to experimental group and the other two classes to control group. Portfolio instruction was administered to the experimental group for 10 weeks, and traditional instruction to the control group. Data on students' creativity and scientific inquiry ability were collected prior to and after the treatment for both groups. Students' perception on portfolio instruction was investigated with experimental group after the treatment. The results of this study are as follows: (1) Portfolio instruction had a significant positive effect on creativity; (2) Students' originality, one of sub-domain of creativity, showed marked increase after portfolio instruction; (3) Portfolio instruction had a significant positive effect on scientific inquiry ability; (4) Integrated inquiry ability, a sub-domain of inquiry ability, improved meaningfully after portfolio instruction; and (4) Students' perception on portfolio instruction is very positive.

The purpose of this study is to develop the model of constructivist multimedia-assisted instruction(CMAI) and to analyze the effect of it in the secondary school geography. The main results are as follows : (1) The conceptual model of CMAI can be defined as an instruction aiming at making a person who has self-directed learning ability through constructivism and multimedia. The procedural model of CMAI based on PIDA instructional strategy is divided into four stages : prediction & explanation, inquiry activity, discussion & fixation, application & synthesis stage. (2) CMAI is typed by offline CMAI and online CMAI. that is, O/WCMAI(online CMAI by web-based courseware). Offline CMAI is subdivided into P/TCMAI(offline CMAI by presentation-based courseware) and C/RCMAI(offline CMAI by cd-rom based courseware) according to authoring tool and function. (3) Offline constructivist multimedia course-ware(offline courseware) was developed for 2 periods as the material to analyze the effect of CMAI. Offline courseware is received development level of it. (4) After offline courseware being applied to the class, the effect of it according the types of the CMAI instruction(lecture instruction, whole teaching, individualized learning, cooperative learning) was analyzed. As the result of analyzing the descriptive statistics of the level of learning achievement and instruction response, there isn't big relationship between them. As the result of analyzing the inferential statistics of the level of learning achievement, there wasn't significant difference between the types of CMAI instruction in whole student of the classes and certain students who improved their grades. But as the result of analyzing of the level of instruction response, there was significant difference between lecture instruction and other types of the CMAI instruction(whole teaching, individualized learning, cooperative learning).

While the average-case performance is important for general-purpose applications, worst-case performance is crucial for real-time systems to ensure schedulability and reliability. Recent work has shown that simple prefetching techniques such as the Next-N-Line prefetching can benefit both average-case and worst-case performance; however, the improvement on the worstcase execution time (WCET) is rather limited and inefficient. This paper presents two instruction prefetching approaches that are specially designed to enhance the worst-case performance, including the loop-based prefetching and WCET-oriented prefetching. Our experiments indicate that both instruction prefetching techniques can achieve better worst-case execution cycles than the Next-N-Line prefetching while having various impacts on the average-case performance.

The purpose of this paper is to develop a technical writing model suitable for engineering students based on the practice of technical writing using the patent application form for engineering students. The Dick & Carey model was used to design the teaching of technical writing using the patent application form. In particular, the instructor communicates with the learner and instructs the learner to produce and express students' own ideas. Instruction design in technical writing progresses consists of four steps, such as creating ideas by brainstorming, comprising contents, exercising writing, and feedback. Feedback occurs between an instructor and a learner and also does among students. As writing is proceeding step by step, instruction design for technical writing should come forth with specific methods to make students practice writing in work. Following these steps will help engineering school students to make up new products after graduating university.

Instructional contents are used to demonstrate a technical process to teach and walkthrough certain procedures to carry out a task. This type of informational content is widely used for teaching and lectures in form of tutorial videos and training videos. Since there are questions and uncertainties for what could be the killer application for the novel wearables, we propose a self-instruction training application on a smart glass to utilize already-available instruction videos as well as public open data in creative ways. We design and implement a prototype application to help users train by wearing smart glasses specifically designed for two concrete and hand-constrained use cases where the user's hands need to be free to operate. To increase the efficiency and feasibility of the self-instruction training, we contribute to the development of a wearable killer application by integrating a voice-based user interface using speech recognizer, public open data APIs, and timestamp-based procedural content navigation structure into our proof-of-concept application.

Background: Elderly patients visiting pain clinic may be at greater risk of misunderstanding the explanation because of age-related cognitive decline. Video instruction may provide a consistent from of teaching in a visual and realistic manner. We evaluated the effect of educational video on the patient understanding and satisfaction in a group of geriatric patients visiting pain clinic. Methods: Ninety two patients aged more than 60 years old who were scheduled for transforaminal epidural block were recruited. After exposure to either video or paper instruction process, each patient was asked 5-item comprehension questions, overall satisfaction and preference question. During follow-up period, number of outpatient referral-line call for further explanation was counted. Results: We observed significantly better comprehension in the video education compared with paper instruction (P < 0.001). Patient satisfaction was also higher in the video group (P = 0.015), and patients visiting pain clinic were more preferred video instruction (P < 0.001). Proportion of referral-line call for further explanation were similar (P = 0.302). Conclusions: Video approach to instruction process before consent improves treatment comprehension in geriatric patient visiting pain clinic.

The purpose of this study was to explore the effect of an explicit word instruction for EFL beginning readers and their perception on the learning experience. Data were attained from 16 fourth graders who took English class as a development activity. Data include the results of pre- and post-test of high frequency sight word recognition, oral reading ability, students' survey responses, and teacher observation. The descriptive statistics were obtained for the result of the pre- and post-test. The findings from the student survey and teacher observation were also provided and interpreted to better understand the result of project and students' perception on the learning experience. The followings are the results of this study. The word recognition ability of the students was dramatically improved after the project. The students were satisfied with the overall learning experience perceiving it as helpful and fun learning. They expressed that the explicit word instruction helped their word recognition and reading ability. The results also supported that the confidence of students on their reading ability were heightened. Several suggestions are made for teachers and researchers on the word instruction for young EFL learners who are beginning readers.
