The effects of combining simulations and laboratory experiments on Zimbabwean students’ conceptual understanding of electric circuits

ABSTRACT

Background

Information Communication Technologies are increasingly present in the African educational system at all educational levels. However, their integration into pedagogical practices to improve the quality of teaching and learning across disciplines remains the exception.

Enhancing quality with a research-based student feedback instrument: a comparison of veterinary students’ learning experiences in two culturally different European universities

This paper explores the value of a research-based student inventory from the quality assurance point of view in two culturally different European higher education institutions for veterinary education. Perceived heavy workload is a well-known problem in veterinary studies and is a challenge to the quality of learning. First- and third-year students in both institutions responded to an inventory consisting of items regarding their approaches to learning, self-efficacy, study workload and the teaching-learning environment. There were differences in students’ approaches to learning and perceived workload between the two institutions. In both contexts, the strongest predictor of the workload turned out to be the surface approach to learning. Self-efficacy showed a positive correlation with the deep approach to learning and organised studying. The strengths of the teaching-learning environment varied between the institutions. Moreover, the present study discusses how the gained information could be used in improving the teaching-learning environment and students’ learning.     

A sociocultural perspective on mediated activity in third grade science

This ethnographic study of a third grade classroom examined elementary school science learning as a sociocultural accomplishment. The research focused on how a teacher helped his students acquire psychological tools for learning to think and engage in scientific practices as locally defined. Analyses of classroom discourse examined both how the teacher used mediational strategies to frame disciplinary knowledge in science as well as how students internalized and appropriated ways of knowing in science. The study documented and analyzed how students came to appropriate scientific knowledge as their own in an ongoing manner tied to their identities as student scientists. Implications for sociocultural theory in science education research are discussed. John Reveles is an assistant professor in the Elementary Education Department at California State University, Northridge. He received his Ph.D. from the University of California, Santa Barbara in 2005. Before pursuing his Ph.D., he worked as a bilingual elementary school teacher for 3 years. His research focuses on the development of scientific literacy in elementary school settings; sociocultural influences on students' academic identity; equity of access issues in science education; qualitative and quantitative research methods. Within the Michael D. Eisner College of Education, he teaches elementary science curriculum methods courses, graduate science education seminars, and graduate research courses. Gregory Kelly is a professor of science education at Penn State University. He is a former Peace Corps Volunteer and physics teacher. He received his Ph.D. from Cornell in 1994. His research focuses on classroom discourse, epistemology, and science learning. This work has been supported by grants from Spencer Foundation, National Science Foundation, and the National Academy of Education. He teaches courses concerning the uses of history, philosophy, sociology of science in science teaching and teaching and learning science in secondary schools. He is editor of the journal Science Education. Richard Durán is a Professor in the Gevirtz Graduate School of Education, University of California, Santa Barbara. His research and publications have been in the areas of literacy and assessment of English Language Learners and Latino students. He has also conducted research on after school computer clubs, technology and learning as part of the international UC Links Network. With support from the Kellogg Foundation, he is implementing and investigating community and family-centered intervention programs serving the educational progress of Latino students in the middle and high school grades.     

浅论王廷相的认识论

王廷相在认识的来源上提出“合内外而一之” ,论证了一切认识都是主观对客观的反映 ;在认识的途径上 ,提出可分“见闻”和“思虑”两阶段 ,并阐述了两个阶段的区别和联系 ,反对“见闻”和“思虑”之外 ,别有所谓“德性之知” ;在知与行的关系上提出“知行兼举” ,强调实践的极端重要性 ,发展了古代朴素唯物主义认识论。当然 ,其认识论也有缺陷     

论学生的主体地位在教学活动中的建构

中小学教学活动，关键在于充分体现教学的主体性精神。承认学生在教学中处于主体地位，即承认学生在教学中既是认识活动的主体，又是价值活动的主体。活动是学生主体地位得到落实的重要保证。学生的活动及活动方式必须得到巧妙的安排和组织。
