In this section of Resonance, we invite readers to pose questions likely to be raised in a classroom situation. We may suggest strategies for dealing with them, or invite responses, or both. “Classroom” is equally a forum for raising broader issues and sharing personal experiences and viewpoints on matters related to teaching and learning science.The demonstration described in this article is to show that while H2O ice floats in water, D2O ice sinks in water, proving the higher density of ‘heavy water’. This experiment can be done in a classroom or in an auditoriam. 相似文献

The main purpose of this paper is to demonstrate how to apply the Hierarchical Linear Modeling (HLM) technique to multi-wave
Curriculum-Based Measurement (CBM) measures in modeling academic growth and assessing its relations to student- and instruction-related
variables. HLM has advantages over other statistical methods (e.g., repeated measures ANOVA, Structural Equation Modeling)
in modeling academic growth. The advantages include allowing more flexible research designs in collecting multiple data points
and estimating growth rates and their relations to correlates in more reliable, accurate ways. CBM, as a multi-wave progressmonitoring
system, also has distinctive psychometric features that facilitate longitudinal research on academic skill development. These
features include provision of multiple data points within short time periods, good validity and reliability, and sensitivity
for detecting small degrees of change. Finally, research questions related to assessing the academic growth of students with
learning difficulties and using assessment results to improve educational practices for them are discussed 相似文献

A case study is reported involving 32 applied and academic program student volunteers aged 15–18 years from two high schools located in Northern Ontario, Canada. Students were interviewed regarding a number of educational policy and school climate issues. The study examines perceptions of rights as an aspect of the school learning environment. The need for greater school community and additional supports for struggling students was voiced by students across both program groups. Students strongly endorsed either a meritocratic or an equalitarian perspective on rights issues with both philosophies represented to some extent in both program groups. Surprisingly, students across both program groups expressed little interest in their education rights or their legal rights generally. The importance of fostering school community and student interest in rights issues is discussed. Also considered is the role of the social science researcher in providing youth a forum for the discussion of social policy issues. 相似文献

The aim of this study is to design and implement a digital interactive globe system (DIGS), by integrating low-cost equipment to make DIGS cost-effective. DIGS includes a data processing unit, a wireless control unit, an image-capturing unit, a laser emission unit, and a three-dimensional hemispheric body-imaging screen. A quasi-experimental study was conducted to evaluate the learning effectiveness of our system. A total of 105 junior high-school students from Taiwan participated in this 8-week experiment. The students were divided into three individual groups of 35 students each, with one control group and two experimental groups (EG1 and EG2). The results of one-way mixed design ANOVA indicated that participants in the experimental group, who used the DIGS, outperformed the other two groups, in the post-test as well as in the delayed test. These findings demonstrate that the proposed DIGS can effectively enhance the performance of the learners in an Earth Science course. 相似文献
