Development and validation of human population growth scale in the context of sustainability

Demirci, Sinem
The aim of this study is to construct valid and reliable scales to identify beliefs towards the effects of human population growth, and to explore the HPG beliefs of preservice teachers at Middle East Teachnical University. HPG is one of the essential elements of education for sustainable development and preservice teachers were included in this study since they are future teachers to implement ESD programs. The data were collected in the fall term of 2013 2014 academic year from six hundred fifty eight preservice teachers from Faculty of Education at METU pursuing different undergraduate program. Human Population Growth Belief Scale was constructed as a measuring tool and implemented in classroom environment settings. The results of Exploratory and Confirmatory Factor Analyses revealed that BHPG scale is valid and reliable scale for determining pre-service teachers beliefs towards the effects of HPG. The results proposed six dimensions named as Requirements to Support HPG, NeoMalthusian Environmentalism, Population and National Economy, Quality of Human Life, Population, Resources, and Environment, and Population and Migration. Moreover, descriptive analysis results indicated that pre-service teacher did not have complex and consistent belief systems towards the effects of HPG concept


Development and application of a four-tier test to assess pre-service physics teachers' misconceptions about geometrical optics
Kaltakçı, Derya; Eryılmaz, Ali; McDermott, Lillian Christie; Department of Secondary Science and Mathematics Education (2012)
The main purpose of this study was to develop and administer a four-tier test for assessing Turkish pre-service physics teachers’ misconceptions about geometrical optics. Sixteen pre-service physics teachers, who were selected by maximum variation and convenience sampling methods from three state universities in Ankara, were interviewed in the contexts of plane mirrors, spherical mirrors, and lenses. From these interviews and the studies in the literature, the Open-Ended Geometrical Optics Test was develope...
Investigating pre-service science teachers’ understandings and use of models
Yenilmez Türkoğlu, Ayşe; Öztekin, Ceren; Department of Elementary Education (2013)
To gain a better understanding of pre-service science teachers’ (PSTs’) views of models, a case study was conducted with fourteen PSTs in a large public university in Ankara. The study aims to provide an answer to the research question, ‘What understandings do PSTs possess about scientific models and the models used in science education?’ and to explore how they use these models in their classroom practices. Data were collected using an open-item instrument, semi-structured interviews, class observations, a...
Development of pre-service science teachers’ nature of science views and nature of science instructional planning within a contextualized expilicit reflective approach
Bilican, Kader; Çakıroğlu, Jale; Öztekin, Ceren; Department of Elementary Education (2014)
The main focus of the study was to explore pre-service science teachers’ understanding of NOS and translation of this understanding into their instructional planning for teaching NOS within the contextualized explicit reflective NOS based approach. The study, first investigated pre-service science teachers’ development of NOS views as a result of explicit reflective NOS instruction in the context of HOS based science method course, which was designed to improve pre-service science teachers’ both NOS views a...
Exploring preservice science teachers’ energy conservation behavior through motivation, psychological needs and attitude: further supported with their awareness
Çakır Yıldırım, Birgül; Yılmaz Tüzün, Özgül; Department of Elementary Education (2017)
The primary focus of this study was to examine the relationships among attitudes toward energy conservation, self-determined motivation and basic psychological needs of preservice science teachers. To this end a model showing the relationship among these variables was suggested. In order to better understand the observed relationships in the model, interviews with PSTs were conducted. For the purpose of the study mixed method was used. In quantitative part of the study, 1136 preservice science teachers, who...
Development of Teacher Autonomy Scale for Turkish Teachers
Ulas, Jale; Aksu, Meral (2014-10-31)
The purpose of this study was to develop a valid and reliable instrument in order to measure the level of autonomy of Turkish classroom teachers. For this purpose, an 18-item 5-point Likert type scale was developed and tested. Data were collected from 292 classroom teachers (teaching at grades 1 to 4) working in state elementary schools located in five main districts of Ankara, and analyzed through Exploratory Factor Analysis (EFA) in order to investigate the factor structure of the instrument. EFA resulted...
