Focusing on the variables that can affect both academic achievement and the well-being of students has been crucial for their development, making schools effective and designing educational policy as well as curriculum. The study has aimed to investigate the effect of peer bullying on academic achievement and to determine moderators in the…

The discourse of quality has permeated everyday discussions about education, yet the concept as such remains complex. Moreover, during the constant struggle to improve educational quality, governments have increasingly devoted attention to the results of international large-scale assessments. As those results are used to inform policy decisions to…

There is increasing interest in meta-analysis in different fields due to the need to combine the results of primary research. One of the crucial concepts in combining results is weighting. This study examines how Hunter and Schmidt's method, weighting by sample size; Hedges and Vevea's method, weighting by inverse variance; and Osburn and…

In this systematic literature review, we examined the theoretical frameworks, construct operationalisation, and quantitative results as they relate to student motivation and science achievement in TIMSS studies. Our synthesis of findings derived from an international dataset present notable value in that the patterns identified regarding the…

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…

By measuring students' attitudes towards science using Rasch modelling, the present study investigated the factors related to elementary students' attitudes toward science at both the individual- and school- levels using HLM in China, where students are often reported to have high achievement in science with below-average attitudes towards the…

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 racial and ethnic makeup of the United States is in constant flux and is expected to experience substantial increases in racial and ethnic diversity over the next four decades. The problem the American educational system faces is attempting to problematize race/racism in its educational system and creating a system to counteract educational…

One of the guiding principles highlighted in "A Framework for K-12 Science Education" (NRC 2012) states that "children are born investigators," claiming that students construct their own understanding of the natural world even before they learn about it in formal learning settings. Even if students lack a thorough…

Background and Context: We explored how learning trajectories (LTs) might be used to design variables instruction. Objective: We aimed to develop an LT for variables and use it to guide curriculum development for fourth graders working in Scratch in an integrated mathematics+CS curriculum. Method: We synthesized learning goals (LGs) and levels of…

This report summarizes the findings of a systematic review of practice-based literature on teaching about interdependent relationships in ecosystems to upper elementary students. The report is a product of the Knowledge Assets to Support the Science Instruction of Elementary Teachers (ASSET) project. ASSET is exploring a method for collecting and…

Modifying the environment is a characteristic of the human species. With deforestation and the expansion of urban centers, diseases known in animals have begun to be described in humans. Science textbooks constitute an instrument of great importance in understanding this issue. This study evaluated the main science textbooks, recommended by the…

Textbooks are one of the primary teaching tools frequently used in schools and most teachers use them in their classrooms (Sanchez and Valcarcel, 1999). Since there are a lot of abstract concepts in science education, images in science textbooks play a vital role in the learning process (Kenan et al., 2011). Concretization of abstract concepts may…

In this meta-analysis, I have reviewed published and unpublished research on single-track, year-round education's effect on science and social studies achievement, 2001-2016. Of 30 studies that met inclusion criteria and had data from which an effect size estimate could be calculated, 7 reported science outcomes (18 effect size estimates) or…

Problem Statement: Since the 1970s, scientific literacy has been a major goal of national educational systems throughout the world, and thus reform movements in science education call for all students to be scientifically literate. Despite some good curricular changes and developments across the globe, much remains to be achieved. Given that…
