解构与重构：将小学科学课程转换为移动学习课程

Transforming Primary Science Learning through a Mobilized Curriculum

移动通讯技术可以支持随时随地的无缝学习，而传统的教学材料没有为学生成为自我导向的社会学习者做好充分准备。文章主要介绍新加坡某小学三年级和四年级将科学课程转换为学生使用移动设备可以在课堂情境中使用的移动课程的一种方法。作者通过与实验班教师合作改造已有的课程，总结了解构和重构课程过程中使用的方法以及经验。第一个三年级实验班通过实施该课程一年的研究结果表明，实验班的教师和学生通过重新设计的课堂在思想认识和实践方面都产生了预期的变化，而且学生的期末考试成绩也有了明显的进步。文章通过分享一种移动课程设计的方法以期为国内的移动课程开发和实施方面的研究提供参考和借鉴。

The emergence of mobile communication technology allows us to rethink curriculum design and how to integrate mobile technology to support learning. Mobile technology has the potential to facilitate learning at any time and any place (seamlessly). However， traditional teaching materials have not fully prepared for students to become self-directed and collaborative learners. This paper introduces the method of transforming Singapore primary three and four science lessons into mobilized lessons. We describe our approach and experiences in deconstructing and reconstructing an existing curriculum through a co-design approach with teachers in a local school. After one year curriculum enactment and research， the teacher and her students in the experimental class have shown many expected positive changes in their beliefs and practices; students also improved significantly in their year-end science exam. In the paper， we share the methods for developing mobilized curricula for in-class learning that also extends to out-of-class learning to prepare student habits and competence in self-directed learning.
