Food safety science is an important field due to its practical applications in maintaining public safety and confidence in consumer goods. A significant component of food safety science is the detection and regulation of heavy metals in food. Heavy metals such as mercury (Hg) are of particular concern because of their potential to damage the…

Many efforts to reform science educational standards and structure have placed an emphasis on directing learners to communicate about concepts using external representations (ERs). Techniques to develop competencies with ERs often ask learners to develop understanding outside of a physical context while concurrently making connections back to the…

Science teachers in the local area lacked self-efficacy to teach science and were struggling to engage students in science learning, which resulted in student underachievement. Principals reported that teachers' lack of self-efficacy in teaching science may be limiting students' goals for scientific careers. The purpose of this basic qualitative…

We developed and field-tested an active learning exercise designed to provide biology students with the opportunity to consider key aspects of the nature of science as a method of inquiry, particularly the roles of observation and inference in the development of scientific explanations and how scientists deal with uncertainty. In the activity…

A word association test was used to determine knowledge structures on biochemistry concepts of secondary school chemistry students, aged between 18-19 years. The basic biochemistry concepts related to the topic of Carbohydrates that take place in the International Baccalaureate Diploma Programme curriculum were determined as stimulus words:…

In school-based research, isolating the potential effects of a single variable while attempting to maintain typical classroom routines is always a challenge. Unfortunately, the challenges and methodological approaches to overcoming them are often only shallowly reported, perhaps due to word limits or assumptions that those details are irrelevant…

Content coverage is frequently identified by faculty as a barrier to the implementation of student-centered instructional strategies. This need to cover content may be a personal belief faculty hold and/or an external requirement imposed (or perceived to be) on them ("e.g.," by their department, institution, accreditors,…

The aim of this study is to determine the effects of STEM activities carried out with the flipped learning model within the scope of science class on the scientific creativity, perceptions about STEM, and attitudes towards STEM of 4th grade primary school students and to reveal students' opinions about the learning process. The sample of this…

Research has revealed that a small percentage of weekly instructional time in the elementary grades is dedicated to teaching science. Additionally, elementary educators receive limited preparation to teach science concepts compared to math or literacy skills. Therefore, this study examined if utilizing poetry to teach science concepts had a…

The increasing attention in science education reform documents to language and literacy, coupled with the growing linguistic diversity of United States classrooms, means that science teacher educators and researchers are facing an important task of preparing secondary science preservice teachers (PSTs) to teach a language- and literacy-integrated…

Background: Developing upper secondary school students' understanding of the nature of science and technology are important priorities in educational systems worldwide. More research is needed to better understand the conditions under which teaching and learning of epistemological insights become possible, as well as the tools that are necessary…

Background: Photomicrographs are major biological representations which help students understand more about the structures of cells and tissues. Owing to their abstract nature, students often rely on representations in textbooks to develop their understanding of photomicrographs. Purpose: This study investigated how students with low, medium and…

The purpose of this research is to reveal the feelings and thoughts of physics teachers towards Algodoo training within the scope of the 4005 TUBITAK project named Innovative and Technology Supported Applications in Physics Education. This study was carried out with phenomenological research within the context of the qualitative research approach.…

This study aimed to develop a two-tier light concept test to identify student concept understanding of light. The development of the test was carried out through the content validity, construct validity, and reliability test stages using the Item Response Theory (IRT). The sample consisted of 81 students during the second semester at five…

The purpose of this study was to quantitatively assess the integration of computational thinking with learning about biological evolution. Specifically, we investigated the effectiveness of a framework from a recently developed learning progression that emphasises the complex nature of teaching both computational thinking and biological evolution.…
