Developing seventh grade students’ scientific epistemological beliefs, science process skills and lake ecosystem understandings through Lake Eymir education program

Yağlı, Müşerref Büşra
The main purposes of this study were to investigate the effectiveness of an inquiry-based education program on students’ science process skills, scientific epistemological beliefs, understandings of a lake ecosystem and examine their views about the education program. In this study, a single subject experimental research with pretest and posttest design was used. The sample of the study was 52 seventh grade students in a public school located in the Eymir Lake basin, in Golbasi district of Ankara. The education program had 8-week in-classes (16 hours), 4-week fieldworks (16 hours) and 2 seminars (2 hours) designed in order to fulfill the competencies, values, skills and objectives determined by the Ministry of National Education. In line with this target, the treatment was implemented in 2017-2018 Spring Semester. Science teachers were given training before the course and the implementation of lessons were performed by science teachers of each classroom. Qualitative and quantitative data were collected from the students through Demographic Information Questionnaire, Science Process Skills Test, Epistemological Belief Questionnaire, Lake Ecosystem Drawing Test and Students’ Review Questionnaire. SPSS 25.0 Statistical program and paired samples t-test were conducted for the analysis of the quantitative data and inductive data analyzing methods were utilized for analyzing qualitative data. The results indicated that Lake Eymir Education Program was effective on students’ scientific epistemological beliefs, scientific process skills and understandings of ecosystem conception. Students had also positive views about in-class activities, fieldworks and seminars given by scientists.


Use of self-determination theory to support basic psychological needs of preservice science teachers in an environmental science course
Karaarslan, Guliz; Ertepinar, Hamide; Sungur, Semra (2013-06-01)
In this paper, we examine how the basic psychological needs of preservice science teachers (PSTs) were supported in a series of environmental science course activities informed by self-determination theory (SDT). We collected qualitative data about the PSTs' sense of competence, autonomy, and relatedness through interviews, group discussions, assignments, and reflection papers. Data were analyzed in relation to the instructional design features of the course; namely, collective construction of ideas, studen...
Preservice Science Teachers' Beliefs about Application of Science Process Skills: A Case Study
Yılmaz Tüzün, Özgül (2012-04-01)
The purpose of this study was to investigate preservice science teachers' (PSTs) beliefs about scientific process skills (SPS) and application of SPS during microteaching session. A case study approach was used. Participants were elementary PSTs enrolled in the practice teaching in elementary education course. Findings revealed that PSTs were not proficient in teaching SPS to students, however, their beliefs about SPS were found as satisfactory. After examining 200 lesson plans, it was observed that 77 of t...
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...
Learner Characteristics and Understanding Nature of Science Is There an Association?
Cetinkaya-Aydin, Gamze; Çakıroğlu, Jale (2017-11-01)
The purpose of this study was to investigate the possible associations between preservice science teachers' understanding of nature of science and their learner characteristics; understanding of nature of scientific inquiry, science teaching self-efficacy beliefs, metacognitive awareness level, and faith/worldview schemas. The sample of the current study was 60 3rd-year preservice science teachers enrolled in the Nature of Science and History of Science course. Using a descriptive and associational case stu...
Novice and experienced science teachers’ conceptual knowledge of evolutionary theory within the context of micro-and macroevolution
Yesilyurt, Ezgi; Öztekin, Ceren; Çakıroğlu, Jale; Deniz, Hasan (Informa UK Limited, 2019-01-01)
The purpose of this study was to explore science teachers' conceptions about micro-and macro-evolutionary processes. In this study, a case study was employed to compare and contrast novice and experienced middle school science teachers' evolution conceptions. The data were collected using four micro-and macro-evolutionary scenarios alongside cognitive interviews. The findings illustrated that while the novice teacher mostly provided non-Darwinian explanations, the experienced teacher predominantly applied k...
