In this research, we interviewed primary school teachers and students with hypothetical situations questions and got a comprehensive picture of the status quo of what is happening in the new mathematics classrooms of Mainland China, that is, teachers' conceptions of mathematics and their teaching approaches influence the students' conceptions of mathematics to a large extent. For the teacher who emphasizes the precision and rigidity of mathematics, her students focus on the superficial characteristics of mathematics. On the contrary, for the teacher who believes that mathematics is an open process, related to real life and rich in content, her students are more interested in mathematics and have more diverse conceptions.

The purpose of this research was to determine the effects of the functional lateralization of the brain variables related to the sex, the scientific attitude and the scientific exploration skills. The science instruction is divided in each type of the lecturing class with the experiment class. As for the degree of SMR brainwave activation in each stage are presented while accumulating the brain waves from the right, left and the whole brain waves are analyzed during the science learning activities. It is therefore reasonable to consider the science instruction types and brain lateralization to enhance the science learning effectiveness. Sensorimotor rhythm brainwave as the low Beta is represented well to show the thought process. Category quantification scores and objective scores are calculated to show the visual positioning map for the relationships of the categories by homogeneity analysis.

Student engagement in high-level, cognitively demanding instruction is pivotal for student learning. However, many teachers are unable to maintain such instruction, especially in instances of non-responsive students. This case study of three middle school teachers explores prompts that aim to move classroom discussions past student silence. Prompt sequences were categorized into Progressing, Focusing, and Redirecting Actions, and then analyzed for maintenance of high levels of cognitive demand. Results indicate that specific prompt types are prone to either raise or diminish the cognitive demand of a discussion. While Focusing Actions afforded students opportunities to process information on a more meaningful level, Progressing Actions typically lowered cognitive demand in an effort to get through mathematics content or a specific method or procedure. Prompts that raise cognitive demand typically start out as procedural or concrete and progress to include students' thoughts or ideas about mathematical concepts. This study aims to discuss five specific implications on how teachers can use prompting techniques to effectively maintain cognitively challenging discourse through moments of student silence.

The widely used low-cost design methodology for IoT devices is very popular. In such a networked device, memory is composed of flash memory, SRAM, DRAM, etc., and because it processes a large amount of data, memory design is an important factor for system performance. Therefore, each device selects optimized design factors such as function, performance and cost according to market demand. The design of a memory architecture available for low-cost IoT devices is very limited with the configuration of SRAM, flash memory, and DRAM. In order to process as much data as possible in the same space, an architecture that supports parallel processing units is usually provided. Such parallel architecture is a design method that provides high performance at low cost. However, it needs precise software techniques for instruction and data mapping on the parallel architecture. This paper proposes an instruction/data mapping method to support optimized parallel processing performance. The proposed method optimizes system performance by actively using hardware and software parallelism.

Universities in Korea have driven universities' new attempts to adopt more learner-centered and active learning in English. Problem-based Learning (PBL) is one of the well-known constructive teaching and learning methodologies in higher education. Our research goal was to design and develop the optimal PBL practices for a college physics course taught in English to promote learning and course satisfaction. For four semesters, we have tried and adjusted PBL components, and looked at the trend of the exam scores and group work achievement in each semester. We found that the number of problems and the duration of problem solving are the critical factors that influence the effect of PBL in a college physics course taught in English by going through iterative implementation. The iterative process of applying, designing, and constructing PBL to physics classes was meaningful not only in that we have found the optimal PBL model for learning a college physics course, but also in that we have been reflecting on the continuous interaction with learners during the course.

Teachers' conception about the nature of science is considered to be an important factor to improve the students' conceptions of that. It is assumed that teachers' conception of the nature of science may be influenced by their views of learning. The first purpose of this study was to investigate the exploratory relationships between teachers' conceptions about the nature of science and their views of learning. The second one was to compare the their conceptions and views of learning before and after science education lectures during 1 semester. We administered the questionnaires for the nature of science and for constructivist's learning, respectively, consisted of 5 dimensions (relativism-positivism; inductivism- deductivism; decontextualism-contextualism; content-process; instrumentalism-realism) and of 6 aspects (student; learning; instruction; teacher; curriculum; evaluations) were administered to 57 pre-service elementary teachers (female=44; male=13) before and after lectures. In pre-test it was revealed that respondents had not the consistent conceptions about the nature of science. The conception of relativism was more dominant than those of positivism, deductivism than inductivism, decontextualism than contextualism, process than content and instrumentalism than realism. They had more constructivist views in the respect of process of learning than in other respects, that is, students, instruction, teacher, curriculum and evaluation. But no significant correlations between the dimensions of the nature of science and the aspects of the views of learning suggest that constructivst views of learning was not deeply related with their conceptions of the nature of science. In post-test we had similar results with those of the pre-test, but the process-content dimensions of the nature of science was correlated with the constuctivist views of learning. Therefore we concluded that elementary pre-service teachers had the constructivist views of learning which was isolated with their conceptions of the nature of science although they had science educations course. We need to develop the course to make the conceptions of the nature of science relate view of learning.

This study investigates the feasibility of incorporating student evaluations of peer review interactions into the course grade for an EFL writing course. The use of such evaluations offers a way to grade the process of writing more directly than using writing portfolios alone. Moreover, evaluating peer review interactions highlights the social aspect of writing, which is valuable in the current post-process climate in writing instruction. The 18 members of a semester-long EFL writing course at a Korean university were trained in peer response for one half of a semester; then performed evaluations of peer review interactions during the second half of the semester as part of their writing course. Student evaluations were examined to reveal whether any bias occurred due to relative age, gender, major, or question type. The results revealed no such biases. Therefore, it is suggested that students are capable of providing fair evaluations of peers, which means the evaluations can be factored into the course grade in order to evaluate the social aspect of the writing process.
