The science and technology program developed by the Ministry of National Education of Turkey aims at training students as science and technology literates. In order to achieve this, method implemented by teachers should enhance science process skills, increase achievement and actualize differentiation in the conceptual structure of students. The present study aims to investigate the effectiveness of guided inquiry experiments over traditionally designed experiments on the acquisition of science process skills, content knowledge achievement and differentiating conceptual structure of 8th grade students about floating, sinking, buoyancy and pressure subjects. Guided inquiry laboratory manuals were developed for the experimental group. Traditional confirmation type laboratory manuals were developed for the control group. The study was conducted with 55 eighth grade students at a private elementary school in the Bahçelievler district, İstanbul. In this quasi-experimental study, two of the three intact groups assigned as experimental group, while the control group. Unit achievement test (UAT), science process skills test (SPST) and two-tiered test for determining differentiation in conceptual structure (DDSCT) were used as data collection instruments. All of these instruments were administered to the students as pre-test and post-test. It was found that guided inquiry experiments were effective than traditional confirmation type experiments in differentiation of students’ conceptual structure about floating, sinking, buoyancy and pressure. However, there was not a significant difference in the effectiveness of both inquiry and traditional methods on enhancing the students’ science process skills and their achievement at the unit of force and motion.

The purpose of this study is to investigate the effectiveness of guided-inquiry approach in science classes over existing science and technology curriculum in developing content-based science achievement, science process skills, and attitude toward science of grade level 6 students in Turkey. Non-equivalent control group quasi-experimental design was used to investigate the treatment effect. There were 162 students in the experimental group and 142 students in the control group. Both the experimental and co...
Design and skill labs: Identifying teacher competencies and competency-related needs in Turkey's national makerspace project
Demirata, Ahmet; Sadık, Olgun (2021-06-01)
Turkey's Ministry of National Education started to establish makerspaces called Design and Skills Labs (DSLs) in every public school across Turkey by 2023. However, public school teachers' qualifications required for DSLs are not clear. This study aimed to find out the necessary competencies for educators in makerspaces, and public school teachers' competency-based needs in DSLs. Mixed methods research design was utilized in this study. First, interviews were held with professionals working in private and n...

Kayaduman, Halil; Delialioğlu, Ömer (Association for the Advancement of Computing in Education (AACE); 2017-06-23)
The aim of the present study is to investigate technology integration self-efficacy beliefs of teachers treated with Learning Technology by Design (LBD) activities. The participants of the study were 24 (2 males and 22 female) English language pre-service teachers taking the “Instructional Principles and Methods” course in the department of Foreign Language Education in a public university in Turkey. The LBD activities were aligned with the course goals and objectives and Web 2.0 tools were utilized. Techno...
