Note is presented on the standard lab from a second year chemistry course. The lab "Determining which of the Seven FD&C Food-Approved Dyes are Used in Making Green Skittles", familiarizes students with the operation of the CHEM2000 UV-Vis spectrophorometer.

Hands on activities with artisan materials used in order to realize different practical devices helpful in learning process are one of the most frequently used activity in science classes. Usually, the main strength of these activities are: a deeper learning, an increased motivation of pupils for actively learning and development of practical…

The aim of this study is to investigate Emiratii high school students' understandings of stoichiometry, their use of metacognitive strategies, and the influence of students' use of metacognitive strategies on their understandings of stoichiometry. Two instruments were used in this study, the first to measure students' understandings of…

The National Research Council ([NRC], 2001) has stated that formative assessment is essential to fulfilling the mission of the National Science Education Standards (NRC, 1996). This paper explores the relative utility of four different types of formative assessment prompts in eliciting middle school students' ideas about sinking and floating.…

This paper presents part of the findings from a comparative study on existing and proposed science curricula of grades IX-X in Bangladesh. It aims to explore relevant research to find out what ideas about science are recommended to include in school science curriculum, and then to compare the existing and proposed curricula in terms of ideas about…

Assessing student-led, open-ended scientific inquiry holds a unique problem for classroom teachers because of the diverse skills and content that emerge from student work. This article provides tangible strategies for teachers to assess divergent student-generated inquiry in a manner that is manageable for teachers, informative for students, and…

Reform efforts in science education emphasize the importance of rigorous treatment of science standards and use of innovative pedagogical approaches to make science more meaningful and successful. In this paper, we present a learning-goals-driven design model for developing curriculum materials, which combines national standards and a…

In science education, students should come to understand the nature and significance of models. In the case of chemistry education it is argued that the present use of models is often not meaningful from the students' perspective. A strategy to overcome this problem is to use an authentic chemical modelling practice as a context for a curriculum…

Research is starting to show that an inquiry-based approach can positively impact student learning. In this paper, the author propose a model of inquiry-based learning with the support of virtual mentorship. They identify the key players involved, define each of their responsibilities and explain how they work collaboratively to develop…

The application of psychology and technology are used in the learning process while we use programmed learning modules. In programmed learning we use the small steps of learning resulting in mastery. The modules helps to respond the learners activity and to give immediate feedback. The learners will get their own timing to go through the lessons…

Educational researchers have suggested that the tension between the learner-centred and teacher-centred pedagogies represents a real classroom issue that influences teaching and learning. This issue may be particularly significant in East-Asian countries such as Taiwan due to some cultural influences. For example, teacher authority is highly…

While it is generally acknowledged that the first years of teaching are the most difficult, little is known about the development of subject matter specialists during this period. In order to add to the knowledge in this area, the present study explores the first year of 114 secondary science teachers as they participate in one of four different…

The conservation of biodiversity is an important socio-scientific issue that is often regarded as a precondition to sustainable development. The foundation for citizens' understanding of conservation issues can be laid down in formal school education. This research focuses on decision-making discussions about biological conservation issues among…

This study is based on data collected during 6 years (12 semesters) in the secondary science methods courses at an urban university in Southern California. The secondary science credential candidates were teaching on emergency permits or internship credentials in local urban secondary schools. They taught science during the day and pursued their…

This document includes the strategies being used by the state of Maryland to reach five goals and six essential outcomes regarding science education for their students. Also included is a discussion of seven recommendations made by committee members and reviewers of this effort to improve the quality and use of science laboratories in Maryland.…
