This study analyzed the comprehension strategies and visuals in two science textbook series for grades 6, 7, and 8 as means of better understanding a core element of the ecological component of science literacy. The iScience [Biggs et al. in iScience (Grade 6), McGraw-Hill, 2015a, iScience (Grade 7), McGraw-Hill, 2015b, iScience (Grade 7),…

A structural/cross-sectional micro-analytic perspective prevails in the Socio-constructivist research of peer knowledge construction. This paper proposes an alternative micro-sequential approach that focuses on the transitions between events during the activity. From this micro-sequential perspective, the study aimed to (a) explore the…

Hands-on activities are considered to be particularly suitable for generating long-term knowledge that increases environmentally friendly behaviour. Appropriate flagship species in a respective curricular context can enable high-quality education. We have developed a teaching concept and material for hands-on activities with bumblebees. This…

With the implementation of Next Generation Science Standards, educators shifted from lecturer to facilitator using inquiry-based learning approaches. Teachers may express anxiety about this role reversal in providing scientific instruction. This study addressed conflicting perspectives in the implementation of inquiry-based learning approaches as…

The aim of this study is to conduct a meta-analysis study to examine the effectiveness of the argumentation-based teaching method in terms of sample, subject, years and some variables (academic success, attitude, interest, etc.). Meta-analysis method was used in this study. In order to gather the studies included in meta-analysis, various sources…

Project-based learning (PjBL) instruction is an inquiry-based method that is beneficial to student achievement and their exploration of 21st-century learning skills, but there is a gap in the literature about how Grades 6 to 8 teachers feel about PjBL and its implementation. The research problem was science teachers in the United States were not…

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…

This paper introduces the LIDO, or the Low-Inference Discourse Observation tool, that captures discourse moves produced by students and teachers in whole-classroom discussions. Coding methods are described, followed by analyses that explore validity of the LIDO through correlations among LIDO-coded discourse moves and between LIDO scores and…

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…

To improve understanding of identities and inverses, and to provide a stronger foundation for future mathematics, Sandra Miles designed a two-part lesson that makes the relationship between identities and inverses explicit. This article illustrates Miles' teaching of the first part of the lesson, focused on addition and subtraction, and then gives…

A differentiated science activity was created for gifted students. The focus is on Sustainable Development Goal 15 (SDG-15) for life on land, enhancing engagement, self-regulated learning skills, and scientific creativity in gifted students. The activity spanned eight lesson hours, with tasks encouraging observation, inquiry, and creative…

In this study, an extracurricular observation module is suggested for the purpose of observing the sustainability of biodiversity based on gathering evidence regarding different seed dispersal processes in the natural environment. These observations were made during the period of the COVID-19 pandemic, a time when human activity inflicted a…

The aim of this study is to examine how the nature of science dimensions are represented in the secondary school 5th, 6th, 7th, and 8th grade science textbooks of the last twenty years. It is also within the scope of the research to investigate how these dimensions in the textbooks changed during the twenty years. The document analysis method was…

Ocean currents play an important role in regulating the Earth's climate by redistributing ocean heat around the planet. One important climate phenomenon that includes several large ocean currents is the Atlantic Meridional Overturning Circulation, which is the process of warm surface currents in the North Atlantic Ocean moving to the Arctic to…

This study examined the level of knowledge the students had about owls by means of drawings and written answers. In the interviews, the students in the lower grades were found to have more limited information and less biological literacy than the ones in the upper grades. The aim was to determine students' knowledge, experience, and sources of…
