A simple and low-cost, DIY-type, Arduino-driven experiment is presented for the study of friction and measurement of the friction coefficient, using a conductive rubber cord as a force sensor. It is proposed for high-school or college/university-level students. We strongly believe that it is worthwhile planning, designing and performing Arduino…

In this paper, we present and discuss the results of a systematic review of concept mapping-based interventions in primary and secondary science education. We identified the following recommendations for science educators on how to successfully apply concept mapping as a method for formative assessment: firstly, concept mapping should be…

In Turkey, science festivals have become more widespread and have begun to be organized especially in secondary schools. The aim of this research was to determine and compare the science festival attitudes of students participating as observers in 4006 TUBITAK science fairs organized at schools. In the research, descriptive survey was employed.…

The present study examines the integration level of the Nature of Scientific Knowledge in secondary school science classes in Greece. The research was designed and organized on the basis of the Cultural-Historical Activity Theory. The activity system of the researchers, who use the proper tools each time, are in network relations with the activity…

To enhance teaching and learning about Earth's climate and global climate change (GCC) in secondary science classrooms, the authors are engaged in a four-year, National Science Foundation (NSF)-funded project to develop, implement, and evaluate a new four-week curriculum module grounded in the use of a data-driven, computer-based climate modeling…

Authenticity is a term that has become ubiquitous within the field of science education, particularly when it relates to the practices of science. These practices are a key feature of science education reform documents in the US. However, a common definition of just what makes for the authentic doing of science is hard to come by and certainly…

It has recently been suggested that pedagogical content knowledge (PCK) has a concept-specific nature, beyond the topic-specific level of PCK. This paper reports a case study of three pre-service teachers' reported PCK about three fundamental concepts within the topic of electrostatics, namely electrostatic force, electric field and electric field…

Mathematics is of major importance in science subjects. Unfortunately, students struggle with applying mathematics in science subjects, especially physics. In this qualitative study we demonstrate that transfer of algebraic skills from mathematics in physics class can be improved by using pre-knowledge effectively. We designed shift-problems…

This study aims to determine the perceptions of the use of scientific process skills of in-service and pre-service teachers working in branches related to science courses in secondary and high schools. Therefore, this research was designed based on a relational survey model and was carried out with 150 science teachers in Turkey and 260…

Educational standards and instructional frameworks aim to foster students' scientific literacy, especially their conceptual knowledge. Previous research has examined several instructional approaches to foster students' conceptual learning. Reliable and adequate use of technical terms in science instruction is also essential for fostering students'…

We report on seven secondary science teachers' initial efforts to understand and enact NGSS-aligned teaching. After interviewing and observing them over the course of the school year, we found that teachers revised their lessons to include instructional strategies that aimed to meet the demands of the NGSS. Yet at times, the purpose for which…

The learning model is one of the critical factors in boosting student to have good learning motivation (LM) and cognitive competencies (CC). In two academic years (2016-2017), only 19.6% of Senior High School (SHS) students in Samarinda passed minimal competence in Biology subject. This research was conducted to find out a better learning model in…

The Computer has occupied a comprehensive coverage, especially in education scopes, including in learning-teaching processes, testing, and evaluating. This research aimed to develop computerized adaptive testing (CAT) to measure physics higher-order thinking skills (HOTS), namely PhysTHOTS-CAT. The Research Development used the 4-D developmental…

The topic of electric and magnetic fields is fundamental to the physics curriculum in both high school and college. The applied aspect of this topic has triggered the rapid development of modern technology in this era. This paper reported a remote data acquisition system developed for experiments with magnetic fields by coils to support…

Advances in nanotechnology have drawn attention to nanotechnology education. The aim of this study is to determine awareness, exposure, and knowledge levels of science (physics, chemistry and biology) teachers about nanoscience and nanotechnology. Teachers (N=624) from secondary schools in Turkey comprised the working group. Descriptive methods…
