Effectiveness of case-based learning instruction on pre-service teachers’ chemistry motivation and attitudes toward chemistry

Background: The development of primary pre-service teachers’ chemistry motivation and attitudes toward chemistry were examined in order to develop their science literacy using case-based learning. Students’ ideas were emphasized, real-life situations were discussed, and students could share their ideas and knowledge with peers; as a result, students were active in the learning process.

Purpose: The purpose of the study was to investigate the effectiveness of using case-based learning instruction to increase pre-service primary teachers’ chemistry motivation and improve their attitudes toward chemistry as a school subject.

Sample: The subjects of this study consisted of 51 (20 female, 31 male) freshman primary pre-service teachers from an urban university in Turkey. The mean age of the primary pre-service teachers was 21.

Design and methods: One group pre-test and post-test design was used. A chemistry motivation questionnaire and chemistry attitude scale were used for data collection. For the data analysis, two-way repeated measures of ANOVA and repeated measures MANOVA were conducted.

Results: The results indicated that the mean of the attitude score after the treatment was significantly greater than the mean of the attitude before the treatment. The results also demonstrated that there is no significant difference between females and males. According to the results of the study, there is no significant difference between primary pre-service teachers’ chemistry motivation. However, some chemistry motivation constructs mean scores are greater after the treatment.

Conclusions: In sum, it could be stated that case-based learning is helpful for the development of students’ chemistry motivation and attitudes toward chemistry.     

An analysis of burnout and job satisfaction between Turkish headteachers and teachers

This study attempted to explore Turkish headteachers’ and teachers’ burnout and job satisfaction relating to work status, gender and years work-experiences. The purpose of this study is to find out whether there is difference between headteachers’ and teachers’ burnout and job satisfaction in terms of work status, gender and years work-experiences. In this study, quantitative approach was used. A total of 290 subjects (80 headteachers and 210 teachers) responded to the survey. As research instruments, the Job Satisfaction Scale (JSS) and the Maslach Burnout Inventory (MBI), were used to measure dimensions of headteachers’ and teachers’ burnout. The study results indicated that headteachers have more job dissatisfaction and depersonalisation than teachers. Males have less emotional exhaustion but higher depersonalisation than their female counterparts. Subjects participated in this study seemed to be different on depersonalisation and personal accomplishment dimensions on the scale in relation to their work years. More experienced subjects have higher depersonalisation and less job satisfaction than their less experienced counterparts. In contrast, more experienced subjects have higher personal accomplishment than the others.     

A graphical method for relating multiple socio-economic goals to research and development objectives in agriculture

A quantitative graphical method is presented that identifies a set of technologies within an agricultural production sector that best serves a number of socio-economic goals. Technical research objectives that are derived from this set of technologies can be used by agricultural R&D policy planners as a guide when deciding on the selection and encouragement of specific research programmes.The application of this approach is illustrated with an example from sheep husbandry and wheat cultivation in a semi-arid zone in Israel. It is shown that the set of socio-economically viable technologies includes some of those that are applicable today as well as those that require more research. Despite the fact that some technologies do not meet all the goal criteria, they are currently applied for various reasons.It is suggested that the approach developed here can serve to bridge a communication gap between the agricultural development administration and the research establishment when evaluating agricultural R&D policy. It can also be used to determine the socio-economic limits to technological development in a given situation.     

Student Views of Teacher Actions in Science Classrooms Designed to Meet Current Reforms

Science/Technology/Society (STS) as a reform effort has been active in Iowa for three decades. A program called Iowa Chautauqua has evolved over the four decades to promote K-12 STS teaching in Iowa’s 300 school districts. This is a study of how teachers have become Teacher Leaders of the reforms and lead other teachers who enroll as new teachers and schools each New Year. All were involved with Action Research projects each year while also assisting graduate student teams who serve as research associates. In this study, students were asked to identify specific teacher actions that were designed to make student learning more successful. The study examines general student views of teacher actions as well as specific examples of how students interact with the teacher and how the teachers encourage greater student/student involvement. The results show success with STS and how it defines science and affective actions of teachers in classrooms. Student views of Teacher Leaders, new Chautauqua teachers, and Control Teachers with no STS or Chautauqua experiences provide ways of recognizing successes of current reform efforts.     

Government Publications and Gray Literature in Turkey

This paper investigates bibliographic control of government publications and gray literature in Turkey, in order to determine what further measures are needed to support researchers in both Turkey and abroad. It reports the circumstances surrounding the creation of The Bibliography of Government Publications prepared in 1971, and outlines how gray literature was collected in various bibliographies and thesis centers according to types and made available to researchers. The development of systems for publication and access to government publications and gray literature are evaluated in the context of current studies and past endeavors to provide for bibliographic control and access to these sources.     

Does It Matter If I Feel Sorry or Sorry for You? Testing the Roles of Empathy and Sympathy as Mechanisms Driving Viewer Response to a Dramatic Ad

Narrative messages on average produce higher levels of involvement, intention, and behavior than other message formats. Narratives also generate feelings of sympathy and empathy, although few studies have directly compared the roles of each emotion in the persuasion process. This article presents the results of two studies that tested the effect of exposure to a narrative or nonnarrative ad on persuasive outcomes and the roles sympathy and empathy play in the persuasion process. Both studies found that the narrative ad produced higher levels of involvement, intention, and behavior and that empathy played a more important role in persuasion than sympathy.     

Making learning fun: Quest Atlantis, a game without guns

This article describes the Quest Atlantis (QA) project, a learning and teaching project that employs a multiuser, virtual environment to immerse children, ages 9–12, in educational tasks. QA combines strategies used in commercial gaming environments with lessons from educational research on learning and motivation. It allows users at participating elementary schools and after-school centers to travel through virtual spaces to perform educational activities, talk with other users and mentors, and build virtual personae. Our work has involved an agenda and process that may be called socially-responsive design, which involves building sociotechnical structures that engage with and potentially transform individuals and their contexts of participation. This work sits at the intersection of education, entertainment, and social commitment and suggests an expansive focus for instructional designers. The focus is on engaging classroom culture and relevant aspects of student life to inspire participation consistent with social commitments and educational goals interpreted locally. This research was supported in part by a CAREER Grant from the National Science Foundation, REC-9980081 and by the National Science Foundation Grant #0092831.     

Programs of teacher education as mediators of White teacher identity

A growing body of scholarship in teacher education has explored the historical, systemic, interactional, and individual factors that create possibilities and challenges in White teachers’ reconceptualization of their racial identity and of the purpose and nature of their work in a racialized society. However, there has been little attention to programs of teacher education as critical mediators of such learning and change. Through an analysis of in-depth interviews with four prospective White teachers in the United States, we develop a framework of White teachers’ racial identities as situated within racial ideologies and mediated by the context of teacher education programs. The framework helps elucidate how teachers’ racial identities are instantiated through interactions and available identities in a program space, which are in turn shaped both by ideology and program structure and culture. The framework and findings urge an insertion of our own agency, as teacher educators, into the analyses of White prospective teachers’ learning and change, by highlighting our role as individuals who co-construct the programmatic structure and culture that partially instantiates these teachers’ racial identities.
