The purpose of this research is to analyze the structure of academic writing ability of first-year and second-year university students—students who are at the stage of general education. Practitioners and scholars have analyzed students’ writing ability; however, analyses on university students have been limited to those conducted under subjective criteria based on practices in a particular classroom or a certain course. Studies using objective methods have typically been limited to the level of junior-high and high-school students. Thus, the present study analyzed a larger sample of students’ papers at the university level using an objective methodology—factor analysis. 384 assignment papers from various courses written by first-year and second-year university students were evaluated using thirty-five criteria. The criteria were all based on the skills of academic writing without regard to specific fields. Factor analysis indicated five factors relevant to students’ academic writing ability: words and sentences, content, paragraphs, overall organization, and references. This five-factor structure of students’ academic writing ability can be applied in designing an academic writing course as well as in developing a rubric for assessing students’ academic writing at the stage of general education.

多くの魚に複数の種類の有機ヒ素化合物が含まれているが,化学形態ごとに毒性が異なることから,長期摂取による健康影響のリスクを評価するためには,形態別に濃度を定量する必要がある.本研究では,魚中のモノメチルアルソン酸(MMA),ジメチルアルシン酸(DMA),トリメチルアルシンオキサイド(TMAO),テトラメチルアルソニウム(TeMA),アルセノベタイン(AB),アルセノコリン(AC)を対象としたLC-MS/MSによる分析法を開発し,妥当性を確認した.また,福岡市内に流通する魚10種(計50試料)について総ヒ素濃度および各有機ヒ素化合物濃度を調査した.その結果,総ヒ素はすべての試料から0.53~25 mg/kgの範囲で検出され,カワハギからは8.3~25 mg/kgの範囲で検出された.イワシを除く9種においては,総ヒ素濃度に占める各化合物濃度のうち,AB濃度の割合が最も高かったが,イワシにおいてはAB濃度よりDMA濃度の割合が高く,総ヒ素濃度のうち16~24%を占めていた.養殖マダイにおける総ヒ素,ABおよびACの濃度は天然マダイより低かった.

Course evaluations have been widely conducted at Japanese universities to investigate students' understanding or satisfaction. However, most universities struggle to extract useful implications from their course assessments. The purpose of this study is to propose a method and perspective for effectively analyzing student course evaluations and free descriptive answers. We employed the text-mining method, using the free software "KH Coder" to calculate word frequency and find colloquial expressions in students' evaluation data. The marketing research perspective of Customer Satisfaction analysis was applied, comparing free descriptive answers between the "very satisfied" group and the "satisfied" group. We investigated course evaluation of the on-demand academic writing class at Waseda University, especially focusing on students' satisfaction with online feedback from instructors. As a result, particular colloquial expressions were found, such as "satisfied and question, " "scoring and lost points, " and "late and feedback." Statistically significant text analysis revealed three practical implications of class improvement: regulating the timing of feedback, developing the quality of individual support, and standardizing the instructors' grading.
