Measurement is an important concept in school mathematics (Clements, 2003). There are several studies and empirical evidence on students' thinking about geometrical measurement of length, area, and volume (e.g., Barrett et al., 2017; Battista, 2007, 2012; Eames, 2014; Lehrer, Jenkins, & Osana, 1998; Miller, 2013; Outhred & Mitchelmore,…

Reconceptualized Family Resemblance Approach to Nature of Science (RFN) explains science as a cognitive, epistemic, and social institutional system. The aim of this study is to examine the inclusion of Nature of Science (NOS) in the 5th, 6th, 7th, and 8th grade Turkish middle school science textbooks. The "content," "activity,"…

The aim of this study is to determine the students' misconceptions about the digestive system. In this quantitative research, the study group comprised totally 259 sixth-, seventh-, and eighth-grade students. The data were collected through a three-tier diagnostic test and analyzed in terms of scientific knowledge, the lucky guess, lack of…

Energy is a central concept across the sciences and an important goal of science education is to support all students so that they develop a full understanding of the energy concept. However, given the abstract and complex nature of the energy concept, only a few students develop an understanding so that they can use energy ideas to make sense of…

The prevailing portrayal of science and scientists within the public domain is a multifaceted mix of conventional stereotypes. Our study investigates these perceptions among Mexican children, analyzing 816 drawings and descriptions collected from fourth to seventh graders in rural and urban schools in Northwestern Mexico. Drawings were analyzed…

The aim of this research was to explore 11 to 12-year-old children's understanding of the mass of objects made from different materials, and the measurement of this attribute. In depth task-based interviews were conducted with six children attending six different schools; five were in Year 6 and one in Year 7. The children were found to hold…

Despite holding wide-ranging experiences with constant velocity and non-zero acceleration, students wrestling with physical science concepts struggle to demarcate the two distinct characteristics of motion. In fact, this prior experience and loose familiarity with associated terminology often act as an obstacle toward a deep and robust…

This study is an attempt to examine science teachers' views on Argumentation-Based Science Learning (ABSL) and the activities they have prepared. The study employed a qualitative case study method. The working group consisted of 5 science teachers who work in secondary schools affiliated with the Ministry of National Education in Turkey and who…

This study examined the relationship between students' (N = 229) concepts of size and scale and students' achievement in science and mathematics over a 3-year period. Size and scale are considered one of the big ideas in science that permeates disparate science and mathematics content areas, yet little is known about the relationship between…

Literature on school education suggests that teaching and learning science in basic level community schools in Nepal is largely theoretical. Consequently, achievement levels and the understanding of concepts of science is much below policy expectations. This paper builds on a shift from dogmatic lecturing to activity-based pedagogy using school…

The purpose of the study is to determine the knowledge and awareness of gifted children receiving education in the Science and Art Center on nanotechnology. The descriptive survey model was used in the study. The purposeful sampling method was chosen and a total of 160 students receiving education in two Science and Art Centers located in the city…

There is growing interest in the introduction of Einsteinian concepts of space, time, light and gravity across the entire school curriculum. We have developed an educational programme named 'Einstein-First', which focuses on teaching Einsteinian concepts by using simple models and analogies. To test the effectiveness of these models and analogies…

One of the tools that indicate the relationship between concepts is the volume of concept. Volume of concept is displayed that the relations between the concepts of the subject are exhibited in a meaningful harmonious and circular manner in a certain order. The purpose of this research; to be able to determine the usefulness volume of concept,…

The aim of this study was to investigate the effects of the applying the cooperative learning model and the modeling based teaching method together in teaching the subjects "Matter and Heat" and "The Particle Structure and Properties of Matter" on students' academic achievement and science process skills. A quasi-experimental…

The aim of this research is to develop a measurement instrument that is valid and reliable, called the Middle School-Life Science Concept Inventory (MS-LSCI), for the purpose of measuring the life science conceptual understanding of middle school-level students. Although there are several existing concept inventories related to biology concepts…
