Abstract  本研究は,学校・地域・親子をつなぐ「共に歌う」活動としての「みんなで歌おう音楽会」の実践について,その意義と課題について検討することを目的とした。本稿では,特に,実践の経緯と概要を報告しつつ,あわせて,音楽会終演後に実施した参加者対象のアンケート調査を取り上げ考察した。その結果,本実践が,「共に歌うこと」の大切さと「日本文化としての唱歌や日本のうたの継承」の大切さについて,その一端を伝える機会になったことが明らかとなった。また,子育て支援の点からも機能していることが認められた。

Abstract  2019 年度に改訂された幼稚園教諭養成の教職課程に設置される「領域及び保育内容の指導法に関する科目」は,「領域に関する専門的事項」と「保育内容の指導法(情報機器及び教材の活用を含む。)」より構成される。本研究では,従来の「教科に関する科目」が撤廃されたことにより新設された「領域に関する専門的事項」の科目において,具体的にどのような専門知識の学修を要するかについて,「保育内容の指導法」のモデルカリキュラム,及び新幼稚園教育要領の記載内容に照らして検討した。その結果,養成課程の学生自身が領域「言葉」のねらいや内容等を専門的見地から理解して保育実践のための知識や技能を修得することに加え,感じたり,考えたり等の体験的な学びから幼児の視点で言葉の世界をイメージする内容を授業に取り入れる必要性を見出した。

Title Alternative The potential of“ singing activities” in child-rearing facilitated by caregivers: A focus on three mothers
FullText URL cted_010_139_151.pdf
Author HAYAKAWA, Rinko| KATAYAMA, Mika|
Abstract 本研究は,養育者の子育てにおける「歌う行為」に着目し,養育者の立場からその可能性について検討することを目的とした。パイロットスタディとして実施した3名の子育て中の母親への質問紙調査およびグループインタビュー調査を通して,母親の「歌う行為」の様相を探り,子育てにおける有用性について検討した。<br/> その結果,「歌う行為」には,子どもがある行動をとることへの意欲を高めたり,否定的な気持ちを好転させたりする感情の切り替え手段としての有用性のあることが示唆された。言葉だけで伝えるよりも,子どもが好きな歌や多様な音声表現を用いた方が,子どもに受け入れられやすいこと,音楽的な特性自体が子どもの感情に響きやすいことも示された。また,「歌う行為」には,了解可能なメッセージを共有し,親子が楽しく養育行動を進める触媒と成り得る可能性が見出された。
Abstract Alternative The purpose of the present study was to examine the potential of “singing activities” in child-rearing, facilitated by care-givers, from the perspective of the care-givers. A pilot study constituted a survey and group interviews of three mothers currently involved in child-rearing. The effect of mothers’singing activities on child-rearing was considered in various contexts. The results suggested that singing activities have the potential to increase motivation of children to take the initiative in certain behaviors or in altering children’s negative mood to a positive focus. Rather than solely relying on words to influence children, they are more likely to respond, accept, and eventually embrace a message conveyed through their favorite songs or diverse vocal expressions. In short, messages conveyed through singing activities are more likely to resonate with children’ s emotions. Furthermore, singing activities could work as a catalyst for fun-filled and enjoyable growth for both care-givers and children in the process of child-rearing and development by allowing them to share intelligible messages with each other.

Abstract We present an alternative approach to what we call the “standard optimization”, which minimizes a cost function by searching a parameter space. Instead, the input is “orthogonally projected” in the joint input space onto the manifold defined by the “consistency constraint”, which demands that any minimal subset of observations produce the same result. This approach avoids many difficulties encountered in the standard optimization. As typical examples, we apply it to line fitting and multiview triangulation. The latter produces a new algorithm far more efficient than existing methods. We also discuss optimality of our approach.

Abstract We present highly accurate least-squares (LS) alternatives to the theoretically optimal maximum likelihood (ML) estimator for homographies between two images. Unlike ML, our estimators are non-iterative and yield solutions even in the presence of large noise. By rigorous error analysis, we derive a “hyperaccurate” estimator which is unbiased up to second order noise terms. Then, we introduce a computational simplification, which we call “Taubin approximation”, without incurring a loss in accuracy. We experimentally demonstrate that our estimators have accuracy surpassing the traditional LS estimator and comparable to the ML estimator.

Abstract We present a new least squares (LS) estimator, called “HyperLS”, specifically designed for parameter estimation in computer vision applications. It minimizes the algebraic distance under a special scale normalization, which is derived by rigorous error analysis in such a way that statistical bias is removed up to second order noise terms. Numerical experiments suggest that our HyperLS is far superior to the standard LS and comparable in accuracy to maximum likelihood (ML), which is known to produce highly accurate results in image applications but may fail to converge if poorly initialized. Our HyperLS is a perfect candidate for ML initialization. In addition, we discuss how image-based inference problems have different characteristics form conventional statistical applications, with a view to serving as a bridge between mathematicians and computer engineers.

Abstract We present a new method for optimally computing the 3-D rotation from two sets of 3-D data. Unlike 2-D data, the noise in 3-D data is inherently inhomogeneous and anisotropic, reflecting the characteristics of the 3-D sensing used. To cope with this, Ohta and Kanatani introduced a technique called “renormalization”. Following them, we represent a 3-D rotation in terms of a quaternion and compute an exact maximum likelihood solution using the FNS of Chojnacki et al. As an example, we consider 3-D data obtained by stereo vision and optimally compute the 3-D rotation by analyzing the noise characteristics of stereo reconstruction. We show that the widely used method is not suitable for 3-D data. We confirm that the renormalization of Ohta and Kanatani indeed computes almost an optimal solution and that, although the difference is small, the proposed method can compute an even better solution.

Abstract We optimally estimate the similarity (rotation, translation, and scale change) between two sets of 3-D data in the presence of inhomogeneous and anisotropic noise. Adopting the Lie algebra representation of the 3-D rotational change, we derive the Levenberg-Marquardt procedure for simultaneously optimizing the rotation, the translation, and the scale change. We test the performance of our method using simulated stereo data and real GPS geodetic sensing data. We conclude that the conventional method assuming homogeneous and isotropic noise is insufficient and that our simultaneous optimization scheme can produce an accurate solution.

Abstract Because 3-D data are acquired using 3-D sensing such as stereo vision and laser range finders, they have inhomogeneous and anisotropic noise. This paper studies optimal computation of the similarity (rotation, translation, and scale change) of such 3-D data. We first point out that the Gauss-Newton and the Gauss-Helmert methods, regarded as different techniques, have similar structures. We then combine them to define what we call the modified Gauss-Helmert method and do stereo vision simulation to show that it is superior to either of the two in convergence performance. Finally, we show an application to real GPS geodetic data and point out that the widely used homogeneous and isotropic noise model is insufficient and that GPS geodetic data are prone to numerical problems.
