Mathematical communication has been emphasized not only as the process of learning mathematics but also as the objective of mathematics education. However, little studies have been conducted with regard to what to consider and how to implement in the actual classroom for promoting mathematical communication. Given this background, this paper implemented a mathematics instruction in each of 2nd, 4th, and 6th grade classrooms in which specific learning objectives were considered to promote discourse-based mathematical communication. It then analyzed the degree by which such learning objectives were achieved and the linguistic interactions between the teacher and students in each classroom. This paper finally provided issues and suggestions for effective discourse-based instruction in mathematics classroom by analyzing similarities and differences among the three classrooms.

This study introduces and experimentally validates a novel approach that combines Instruction fine-tuning and Low-Rank Adaptation (LoRA) fine-tuning to optimize the performance of Large Language Models (LLMs). These models have become revolutionary tools in natural language processing, showing remarkable performance across diverse application areas. However, optimizing their performance for specific domains necessitates fine-tuning of the base models (FMs), which is often limited by challenges such as data complexity and resource costs. The proposed approach aims to overcome these limitations by enhancing the performance of LLMs, particularly in the analysis precision and efficiency of national Research and Development (R&D) data. The study provides theoretical foundations and technical implementations of Instruction fine-tuning and LoRA fine-tuning. Through rigorous experimental validation, it is demonstrated that the proposed method significantly improves the precision and efficiency of data analysis, outperforming traditional fine-tuning methods. This enhancement is not only beneficial for national R&D data but also suggests potential applicability in various other data-centric domains, such as medical data analysis, financial forecasting, and educational assessments. The findings highlight the method's broad utility and significant contribution to advancing data analysis techniques in specialized knowledge domains, offering new possibilities for leveraging LLMs in complex and resource-intensive tasks. This research underscores the transformative potential of combining Instruction fine-tuning with LoRA fine-tuning to achieve superior performance in diverse applications, paving the way for more efficient and effective utilization of LLMs in both academic and industrial settings.

This study investigates the effects of online English writing instruction on university students' writing performance and their anxiety. A total of 34 participants completed the pre- and post- writing tests as well as the surveys regarding perceived anxiety toward English writing. Reflection papers and interviews were employed to triangulate the results of the questionnaires. Quantitative analysis of learners' writing outcomes and surveys revealed that online writing instruction helped improve students' writing skills and reduce writing anxiety. The interviews and reflection papers demonstrated that learners found the writing instruction helpful in reducing somatic anxiety, avoidance behavior, and cognitive anxiety. The current study suggests that adopting non-face-to-face online writing instruction aids EFL students in developing their writing and alleviating writing anxiety.

The number of studies on data-driven learning (DDL) has increased in recent years, and DDL's overall effectiveness as an L2 (second language) teaching methodology has been reported to be high. However, the degree of its effectiveness in grammar instruction, particularly for the goal of correcting errors in L2 writing, is still unclear. To provide guidelines for focused grammar instruction with DDL in the Japanese classroom setting, we aimed to identify the typical grammatical errors made by Japanese learners in the Cambridge Learner Corpus First Certificate in English (CLC FCE) dataset. The results revealed that three error types (nouns, articles, and prepositions) should be addressed in DDL grammar instruction for Japanese English as a foreign language (EFL) learners. In light of the findings, pedagogical implications and suggestions for future DDL research and practice are discussed.

The Purpose of this study was to find out whether there was any difference in adolescents' decision making abilities according to the level of critical thinking in practical problem-based instruction of Home Economics. The subjects of this study ware 147 students from K girl's high school in Daegu. They were divided into two groups. The former was the experimental group, which took' practical problem-based instruction' of Home Economics. The later was the control group, which took the typical lecture-based instruction. Factor analysis, Cronbach ${\alpha}$, correlation, and two-way ANCOVA were Performed for data analysis. The results of this study are as follows: First, there was no significant difference in the steps of problem identification and information search of the decision making according to teaching methods and the level of the critical thinking ability. Second, the adolescents who took the practical problem-based instruction had shown more improvement in the steps of alternatives consideration and value of the decision making ability than those who took the typical instruction. Third, the adolescents with the high level of critical thinking ability have made much more improvement than those with the low. And it was found that in the case of adolescents with the low level of critical thinking ability, those who took the practical problem-based instruction have made much more improvement than the others who took the typical instruction. On the other hand, in the case of adolescents with the high level of critical thinking ability, those who took the typical instruction improved much more than the others who took the practical problem-based instruction.

The state-of-the-art techniques in multicore timing analysis are limited to analyze multicores with shared instruction caches only. This paper proposes a uniform framework to analyze the worst-case performance for both shared instruction caches and data caches in a multicore platform. Our approach is based on a new concept called address flow graph, which can be used to model both instruction and data accesses for timing analysis. Our experiments, as a proof-of-concept study, indicate that the proposed approach can accurately compute the worst-case performance for real-time threads running on a dual-core processor with a shared L2 cache (either to store instructions or data).
