Recently, there have been several on-demand learning systems that are not restricted by learning time or place. However, in these systems, learning content is prepared in advance for each learning course, or learning content of different difficulty levels is prepared, and learners select their learning contents. In contrast to these conventional systems, many studies have been conducted on learning systems that can grasp the learning state of individual learners and provide them with most suitable learning content. We experimentally verified a method for estimating the difficulty level of a task by focusing on alpha and beta waves. However, in practice, it is not feasible to have learners wear an electroencephalograph (EEG). This study aims to discover biometric information that can be measured by a nonwearable device as an alternative to EEG for estimating the learning state.

本発表では，小学生がおこなう向社会的行動について検討することを目的とした。調査協力者は，三重県A市の小学校1年生から6年生までの合計479名（男子245名，女子234名）であった。調査の実施時期は，2019年10月上旬であった。日常生活の中でおこなっている向社会的行動について，自由記述を求めた。本発表では「誰に」を向社会的行動の相手として，KH Coderの計量テキスト分析を行った。齋藤・杉山（2021）（日本教育心理学会第63回総会）では，向社会的行動の相手をコーディングして，10コードを抽出した。KH Coderのコーディング・クロス集計の機能で，各コードと性別（男子・女子）の関連を確認した。χ2 検定により「きょうだい・いとこ他（男子15，女子39）」「父母（男子16，女子6）」において有意な連関がみられた。本研究から小学生がおこなう向社会的行動の相手には性差があり，女子は男子よりも「きょうだい・いとこ他」を，男子は女子よりも「父母」を相手として，向社会的行動をしていることが示唆された。

There are various difficulties encountered by learners during learning such as good or bad learning content, the difficulty level of the learning content, and the degree of learning proficiency. It is possible to detect these difficulties by measuring the browsing history, editing history, and biological information such as brain waves or eye-tracking information. In this paper, we aim to detect the learning state of each learner by measuring brain wave information during learning of visual programming using the Minecraft educational edition. Furthermore, the detected learning status is statistically correlated using the results of a questionnaire conducted after the experiment. The results show that the assessment of task difficulty by learners is more significantly affected by the experience with Minecraft than by the experience with programming.

In a flipped classroom, the roles of a classroom and homework are reversed. We propose a method for increasing the effectiveness of the flipped classroom lessons based on the self-study log information. Specifically, when students study by e-learning at home, we collect and analyze their learning logs and then classify students into groups based on their study time and the degree of understanding of the material. We call our proposed method a grouped flipped classroom. We applied it to actual lessons during 16 weeks in the autumn semesters of 2017 and 2018 at the Shonan Institute of Technology. The results revealed that students’ performance improved after the grouped flipped classroom lessons, especially in the group of students who had low understanding during self-study: there was a statistically significant difference between their average scores in the tests after the self-study and after the face-to-face lessons. In addition, the average scores in the tests after the face-to-face lessons were higher for students in the grouped flipped classroom than for students in conventional style classes (lecture style class and mixed ability class).

The objective of this study was to investigate the factors, including the frequency of therapeutic intervention (physical therapy: PT, occupational therapy: OT and speech therapy: ST), that infl uence the recovery of activities of daily living (ADL) related motor functions in patients with stroke based on stratifi cation by ADL severity at admission.

Abstract The thermal transformations of the following three types of nickel(II) complexes were investigated by means of TG-DSC analyses: [Ni(t-chxn)2(H2O)2]X2, [Ni(c-chxn)3]X2·nH2O, and [Ni(t-chxn)3]X2·nH2O (X=Cl−, Br−, and NO3−), where c- and t-chxn denote cis- and trans-1,2-cyclohexanediamine respectively. The distorted octahedral [Ni(t-chxn)2(H2O)2]X2 complexes (X=Cl− and Br−) are thermally deaquated to form yellow complexes, which then turn into parental diaquabis-complexes in the air at room temperature. [Ni(t-chxn)2(H2O)2] (NO3)2 undergoes a thermal deaquation-anation reaction. The octahedral tris(c-chxn) complex is converted into a square planar bis(c-chxn) one by the evolution of one molecule of the ligand upon heating, whereas tris(t-chxn) complex became a distorted octahedral bis(t-chxn) one with anion coordination. In this paper, the stereochemical thermal changes of the complexes in the solid state will be discussed with regard to the steric configuration of the ligands.

Abstract Metal chelates of cis- and trans-2-aminocyclohexanecarboxylic acids with divalent metals were newly synthesized and the binding ratios were found to be 2:1. Measurements of pKa of cis- and trans-ligands, as well as the stability constants of Cu and Ni chelates were performed and the stability constants of cis chelates were found to be larger than those of the corresponding trans chelates.
