Effectiveness of Case-Based Learning Instruction on Epistemological Beliefs and Attitudes Toward Chemistry     

Aylin ?am  ?mer Geban 《Journal of Science Education and Technology》2011,20(1):26-32

The purpose of the study was to investigate the effectiveness of case-based learning instruction over traditionally designed chemistry instruction on eleventh grade students’ epistemological beliefs and their attitudes toward chemistry as a school subject. The subjects of this study consisted of 63 eleventh grade students from two intact classes of an urban high school instructed with same teacher. Each teaching method was randomly assigned to one class. The experimental group received case-based learning and the control group received traditional instruction. At the experimental group, life cases were presented with small group format; at the control group, lecturing and discussion was carried out. The results showed that there was a significant difference between the experimental and control group with respect to their epistemological beliefs and attitudes toward chemistry as a school subject in favor of case-based learning method group. Thus, case base learning is helpful for development of students’ epistemological beliefs and attitudes toward chemistry.  相似文献   

How young people respond to learning spaces outside school: A sociocultural perspective     

Alan?PeacockEmail author  Nick?Pratt 《Learning Environments Research》2011,14(1):11-24

This article focuses on educational enterprises outside the formal sector, such as museums, botanical gardens and interactive science centres. International research is drawn on to illuminate how design, culture, educational strategies and settings combine to affect the way in which young people respond to experiences on offer, leading to analysis of the impact of such settings in promoting learning, and the likely implications for those who staff such venues. Aikenhead’s concept of the educator as ‘culture broker’ is developed to suggest ways in which learning might be best supported. It envisages a shift from ‘delivery’ strategies targeted at large groups towards approaches which focus on what learners choose to know about using dialogue between children and ‘known and trusted people’. Analysis of observed responses in various settings is undertaken from a sociocultural perspective using the notion of communities of practice. Implications for the roles of education managers and their staff in further research are developed.  相似文献   

Spannungsfeld Polyvalenz in der Lehrerbildung

The Bologna Process of higher education reform has led to a vast array of different programs of study in German teacher training. In this article, we firstly analyze the implementation of Bachelor programs in teacher training, comparing profession-oriented programs (i.e. those aiming to train students for the teaching profession from the beginning of studies) to polyvalent programs (i.e. those aiming at broad qualifications and including a late decision to become a teacher). Secondly, we investigate whether students enrolled in these study programs differ systematically in their subjective certainty about their career choice. To answer these questions, we analyze portfolios of documents related to teacher training programs from nine German universities that prepare students for teaching in the academic track. Additionally, we analyze data from N?=?2585 Bachelor and N?=?928 Master degree students. We found that most programs, even when they espouse polyvalence, require an early decision to become a teacher. Moreover, our data confirm findings from earlier studies indicating that student teachers are highly certain about their career choice from the very beginning, with students in polyvalent programs being slightly less certain than those in profession-oriented programs (d?=?0.32).  相似文献   

The Relationship Between Undergraduate Attendance and Performance Revisited: Alignment of Student and Instructor Goals     

James W. Westerman  Luis A. Perez‐Batres  Betty S. Coffey  Richard W. Pouder 《Decision Sciences Journal of Innovative Education》2011,9(1):49-67

We revisit the relationship between attendance and performance in the undergraduate university setting and apply agency theory in the instructor–student context. Building on agency theory propositions in the educational setting advanced by Smith, Zsidisin, and Adams (2005) , we propose that the student and instructor must align goals to promote the student's achievement of performance learning outcomes, and attendance functions as a behavior‐based alignment mechanism to encourage the convergence of faculty and student interests. Further, we propose that attendance does not equally affect lower‐ and higher‐performing students and that absences are also negatively related to students' cumulative grade point average. We test these hypotheses with data from undergraduates enrolled in management courses at a state university in the southeast. Our results show that attendance is positively related to exam performance, there are more pronounced negative effects of an absence for lower‐performing students than for higher performers, and absences are negatively related to a student's cumulative grade point average. We discuss the implications of our findings for students, instructors, and universities as well as practice in teaching and learning.  相似文献   

Interactions of numerical and temporal stimulus characteristics on the control of response location by brief flashes of light     

Fetterman JG  Killeen PR 《Learning & behavior》2011,39(3):191-201

Pigeons pecked on three keys, responses to one of which could be reinforced after 3 flashes of the houselight, to a second key after 6, and to a third key after 12. The flashes were arranged according to variable-interval schedules. Response allocation among the keys was a function of the number of flashes. When flashes were omitted, transitions occurred very late. Increasing flash duration produced a leftward shift in the transitions along a number axis. Increasing reinforcement probability produced a leftward shift, and decreasing reinforcement probability produced a rightward shift. Intermixing different flash rates within sessions separated allocations: Faster flash rates shifted the functions sooner in real time, but later in terms of flash count, and conversely for slower flash rates. A model of control by fading memories of number and time was proposed.  相似文献   

An investigation of the relationship between metacognition and mathematics achievement     

G?khan ?zsoy 《Asia Pacific Education Review》2011,12(2):227-235

The aim of this study is to determine fifth-grade students’ metacognitive knowledge and skills and its relationship with mathematics achievements. A total of 242 primary school students from six different schools were participated in the study. Turkish version of Metacognitive Knowledge and Skills Assessment (MSA-TR) was used to measure metacognitive knowledge and skills. The results demonstrated a significant and positive relationship (r = .648, p < .01) between metacognition and mathematics achievement. Furthermore, research results showed that 42% of total variance of mathematics achievement could be explained with metacognitive knowledge and skills.  相似文献

Function oriented service composition modeling     

刘方方  李成玲  余洁 《上海大学学报(英文版)》2011,15(5):369-374

Formal models for service composition have been proposed with the variation of the requirements of service developers. Some famous models have provided checking and verification techniques and tools for the behavior of service composition. These models generally focus much on the message flow of web services and neglecting the data contained in the exchanged messages among services, which restrict the application range of these models and also the web service techniques. As new kind of services with different protocols and communication methods have appeared, it is needed to model service composition from a new view which is adapted to the new development in service area. In this paper we offer a function oriented model of service composition which treats the composite service as a software system and specify the function of services which can be directly used to the realization by service providers.  相似文献
