Development and validation of nature of science instrument for elementary school students

Yılmaz Tüzün, Özgül
The purposes of this study were to develop and validate an instrument for assessing elementary students’ nature of science (NOS) views and to explain the elementary school students’ NOS views, in terms of varying grade levels and gender. The sample included 782 students enrolled in sixth, seventh, and eighth grades. Exploratory factor analysis factor structures and confirmatory factor analysis fit indices confirmed the existence of the hypothesised four dimensions in the structure of the nature of science instrument (NOSI). These dimensions and associated Cronbach α reliabilities of scores were observation and inferences (0.74), tentative NOS (0.76), imagination and creativity (0.80), and empirical NOS (0.63). Descriptive analyses revealed that the most favourable NOS views were obtained for the empirical nature of scientific knowledge. The students were uncertain about NOS views related to tentative NOS and imagination and creativity. The least favourable NOS views were obtained for observation and inferences.

The purpose of this study was to assess middle school students’ Nature of Science (NOS) views in relation to gender, grade level, and learning environment perceptions in science classes. The sample included 608 middle school students (289 boys and 319 girls) from Grade 7 (n = 286) and Grade at (n =322) attending public schools located in Yenimahalle and Sincan districts in Ankara. The Background Characteristics Survey, The Students’ Views of Nature of Science (SVNOS) and “What is Happening in this Class (WI...
Investigating Elementary School Students' Motivational Traits in Science Classrooms
Gocer, Fatma Yavuz; Sungur, Semra; Öztekin, Ceren (2011-07-01)
This study examined elementary students' motivational traits in science with respect to students' gender and grade levels. A total of 3685 students from 6th, 7th and 8th grade levels participated in the study. Findings showed that gender and grade level differences exist among elementary students. Concerning the gender difference, girls appeared to be more curious, conscientious, and social with a higher level of need for achievement. Moreover, it was revealed that as grade level increased, students' motiva...
Investigation of the relationship between pre-service science teachers' understandings of nature of science and their personal characteristics
Çetinkaya, Gamze; Çakıroğlu, Jale; Department of Elementary Science and Mathematics Education (2012)
The purpose of this study was to investigate the possible relationships between pre-service science teachers' understanding of nature of science (NOS) and their personal characteristics; understanding of nature of scientific inquiry (NOSI), epistemological world views, self-efficacy beliefs regarding science teaching, attitudes towards science teaching, metacognitive awareness level and faith/worldview schemas. The sample of the present study were 60 PSTs that are 3rd year students at elementary science edu...
Examining middle school students' understanding of the nature of science
Çelikdemir, Meliha; Çakıroğlu, Jale; Department of Elementary Science and Mathematics Education (2006)
The aim of this study is to investigate the elementary school students’ understandings of the nature of science (NOS). A total of 1949 students (1026 sixth graders and 923 eighth graders) from six different elementary schools participated in the study. “Nature of Science Questionnaire for Elementary Level (E-NOS)” questionnaire, adapted from Views on Science-Technology-Society (VOSTS) developed by Aikenhead, Fleming and Ryan (1989) and Views on Nature of Science (VNOS-D) constructed by Lederman, Adb-El-Khal...
Exploring the Development of Preservice Science Teachers' Views on the Nature of Science in Inquiry-Based Laboratory Instruction
Ozgelen, Sinan; Yılmaz Tüzün, Özgül; HANUSCIN, Deborah L. (2013-08-01)
The purpose of this study was to explore the effect of the inquiry-based and explicit-reflective laboratory instruction on preservice science teachers' (PSTs) conceptions of the nature of science (NOS) aspects. This study was carried out during the Laboratory Application in Science II course. All 52 preservice elementary science teachers enrolled in the course consented to participate in the study; 37 were female and 15 were male, with a mean age of 22.8 years. All had the same science major background, and...
