Symmetric alteration of four knots of B-spline and NURBS surfaces

INTRODUCTION Modification of knots of a B-spline curve changes the shape of the curve. In some recent pub-lications (Juhász and Hoffmann, 2001; 2003; Hoff-mann and Juhász, 2004; Li and Wang, 2005), the authors studied the effect of the alteration of a single knot on the shape of the curve. Hoffmann (2004) and Li & Wang (2006) applied these theories into the constrained shape modification of B-spline and NURBS curves. Juhász (2001) and Hoffmann & Ju-hász (2005) studied the effe…     

Pedagogical practices of NetNZ teachers for supporting online distance learners

A supportive online learning environment entails teachers using effective pedagogical practices to meet the needs of their students and developing a positive teacher–student relationship to foster learner motivation and engagement. This paper reports a study investigating how 32 secondary teachers in New Zealand taught their online distance classes and how they related to their students. These classes were administered by NetNZ, an online distance education community. An online survey conducted in 2016 found that NetNZ teachers used inquiry-based practices including flipped learning and knowledge-building pedagogies to support agency, autonomy, collaboration, and community development. They also used synchronous and asynchronous communication technologies to overcome barriers of relationship building in online settings. NetNZ was unique in delivering distance education in the New Zealand context in that it used a community approach to encourage a more active participation of its member schools and teachers in delivering distance courses to secondary students.

以学习动机为核心的学习动力在大学生的学习中起着决定性的作用。然而 ,缺乏学习动力的情况在相当一部分大学生身上不同程度地存在着 ,这严重影响了大学生的学习。大学生学习动力缺乏的表现形式多种多样且成因各异 ,如何采取相应措施值得深思。     

从文学接受过程看琼瑶小说

文学接受过程是较为复杂的过程,它是接受主体在文学文本中启动、强化、不断深入展现生命力的动态过程。本文试图用文学接受过程的有关理论从＂从期待视野看琼瑶小说——琼瑶重视读者;从接受心理看琼瑶小说;从读者的接受动机看琼瑶小说＂三个方面来探讨一下琼瑶小说。     

Attaching Importance to the Learner's Affective Factors in English Teaching

Traditional English teaching lacks the consciousness of the importance of learner’s affective factors and has trouble in training the qualified English speakers that the society needs.This paper talks about the importance of learner’s motivation,attitude and personality.It is proposed that teachers should adopt the eclectic method accompanying with student-centered class.Teachers are asked to pay more attention to their different roles and the ways to create a positive climate for learning in class.     

高师函授学员参与学习的动机研究

通过编制高师函授学员参与学习的动机量表,对我国高师函授学员参与学习活动的动机取向及其相关因素进行分析。发现高师函授学员参与学习主要有求知兴趣、职业与经济、他人或环境影响、体验或逃避、服务意识、社交关系六大类动机取向;动机取向与年龄、性别、学历水平等因素均存在相关。     

幼儿教师人际信任与知识分享意愿的关系——兼论知识分享动机的调节作用

本研究选取215名一线幼儿教师作为调查对象,使用逐步多元回归分析探讨了幼儿教师人际信任与知识分享意愿的关系,以及知识分享动机如何在两者之间起调节作用.结果发现,幼儿教师的情感信任对知识分享意愿具有显著的正向作用;幼儿教师的利他主义、互利主义和声誉追求动机均对知识分享意愿具有显著的正向作用.为促进幼儿园学习共同体的形成,应改变幼儿教师知识分享的观念,引导其掌握知识分享的方法;重视幼儿教师之间情感信任的建立,增强知识分享的安全感;关注幼儿教师思想动态,制定有效的知识分享激励机制;对幼儿教师实行差异化管理,加强幼儿园知识分享氛围的创设.
