Few evidence-based instructional practices achieve large-scale use, often remaining only in the schools directly involved in their development. Research on scaling up effective educational practice often lacks sensitive measures of the practice's implementation and the required research protocol. This article describes how we used rate of implementation as a sensitive measure to help identify barriers to implementation of class-wide peer tutoring (CWPT). Using communication technologies and a learning management system, we monitored the rate of CWPT implementation and its research protocol across nine schools in five states. Rate of implementation was defined as the number of weeks in which a school successfully completed the 12 implementation tasks required to reach full implementation. We discuss factors related to the variation in implementation rate (30-50 weeks) between schools, and implications of this measurement strategy for research on instructional practices and the technology used to facilitate scalability research.  相似文献

This study examines the influence of laboratory instruction that engages students in a wide range of the practices of science on Turkish high-school students’ chemistry learning. In this mixed methods study, student learning in two different laboratory settings was compared, one that featured an instruction that engaged students in a wide range of disciplinary practices (through Argument-driven Inquiry – ADI) and similar laboratories in which a more traditional Structured Inquiry (SI) approach was employed. The data sources included a Chemistry Concept test, an Argumentative Writing Assessment, and Semi-structured interviews. After seven weeks of chemistry instruction, students experiencing ADI instruction scored higher on the Chemistry Concept test and the Argumentative Writing Assessment than students experiencing SI instruction. Furthermore, girls who experienced ADI instruction scored higher on the assessments than their majority peers in the same class. The results suggest that Turkish students can substantially improve their chemistry proficiency if they have an opportunity to engage in instruction featuring a broad array of the practices of science.  相似文献

The research to explain student’s self-regulated learning has grown rapidly in recent years. However, the studies on self-regulated learning have shown fascinating but mixed results. Thus, there is a need to identify and describe the key dimensions of self-regulated learning according to an empirical framework in order to integrate these complex results. This study attempts to explore the structure and the pattern of self-regulated learning. In a sample of high-school students, it was found that self-regulated learning consists of three components; cognitive regulation, motivational regulation, behavioral regulation. The result also shows that students can be grouped into six clusters in terms of these components. This study appears to be useful for understanding self-regulated learning conceptually but has some methodological limitations.  相似文献

RAY is a learning environment that includes a flexible ray tracing simulation, graphic tools, and task authoring facilities. This study explores RAY's potential to improve optics learning in high school. In study 1, the teacher used RAY as a smart blackboard with a single computer in the classroom to explore, explain, and predict optical phenomena; to introduce concepts; to interpret experiments and to represent theoretical exercises. A comparative study shows a significant effect on the spontaneous and correct use of the model by students in solving problems and a limited effect on conceptual understanding. In study 2 students, guided by written materials used the simulation individually. Students considered in a systematic manner the relationship between image formation and image observation—a major conceputal stumbling stone. They reflected on the problem-solving activity and reformulated explicity their knowledge in the domain. Case studies describe the interplay between the various aspects of the learning process in the development of conceptual understanding. A comparative study shows the importance of three factors to students' understanding of concepts and their ability to use the ray model: the computerized environment (versus written instruction of similar kind); a task design that addresses directly conceptual difficulties; and the explicit reformulation of ideas.  相似文献

Understanding the nature of chemical thinking and action, as well as their application and impact on our world should be central goals of chemistry education at all educational levels. However, traditional school chemistry is still mostly focused on having students learn the body of declarative knowledge built over the years in the discipline. Achieving changes in curriculum and teaching practices in this context remains a challenging task. Studies in the history and philosophy of the discipline suggest that chemistry has unique characteristics that need to be recognised and considered in chemistry education. Many of these studies point to a pluralism in the discipline, and in the understanding of and about chemistry, that should be characterised and incorporated into our educational models. In this essay, we have attempted to build such a characterisation using conceptual profiles theory to propose a framework that can be used to enrich and support the thinking and action of chemistry teachers at all educational levels.  相似文献

The aim of this paper is to describe the design of chemical engineering laboratory sessions in order to focus them on the learning company approach. This is an activity carried out in the classroom similar to the activities that exist in real companies. This could lead classroom practice to a more cooperative learning and a different style of experimentation. The stated goal is to make a design that seeks to motivate students in a cooperative manner to perform their experiments self-directed and self-organised. The teaching organisation and development of participatory action research are described.  相似文献
