Abstract

This study addressed the role of the reflection-informed learning and instruction (RILI) model on students’ academic success by using CourseMIRROR mobile system. We hypothesized that prompting students to reflect on confusing concepts stimulates their self-monitoring activities according to which students are expected to review their understanding, search for related knowledge, and try to identify the confusing concepts. With this student-reflection information, instructors can thus address students’ difficulties effectively, which can lead to enhanced academic success. We tested our hypothesis by conducting a semester-long quasi-experimental study in undergraduate industrial engineering classes (N?=?153). The analyses revealed that students in the RILI condition performed significantly better than students in the control condition (Cohen’s d = .82). In addition, reflection analysis showed that both quality and quantity of reflections were significantly associated with exam performance. Surveys indicated users highly valued the RIFI model; they rated CourseMIRROR favorably and said they would continue to use it in future classes.  相似文献

The main purpose of this research is to elements and mathematical properties when they are axiomatic structure of the Euclidian geometry forms a determine to what extent preservice teachers use visual dealing with a geometrical construction activity. The coherent field of objects and relations of a theoretical nature; and thus it constitutes a favorable ground for the learning of the reasoning and justification. In geometry, even if the reasoning is assisted by concrete elements such as drawings, it is not based on actions or spatio-visual elements. Arguments based on mathematical properties are required in geometrical reasoning. A successful teaching of the geometry directly depends on the subject knowledge of the teachers. Another purpose is to map out the different kinds of justifications implemented by teachers related to such an activity. Analyses of the responses indicate that a large proportion of preservice teachers use visual elements for their geometrical constructions and they are tended to use naive empiricism concerning their justifications.  相似文献

While there has been a remarkable interest to make computer science a core K-12 academic subject in the United States, there is a shortage of K-12 computer science teachers to successfully implement computer sciences courses in schools. In order to enhance computer science teacher capacity, training programs have been offered through teacher professional development. In this study, the main goal was to systematically review the studies regarding computer science professional development to understand the scope, context, and effectiveness of these programs in the past decade (2004–2014). Based on 21 journal articles and conference proceedings, this study explored: (1) Type of professional development organization and source of funding, (2) professional development structure and participants, (3) goal of professional development and type of evaluation used, (4) specific computer science concepts and training tools used, (5) and their effectiveness to improve teacher practice and student learning.  相似文献
