The aim of this study is to determine the effect of concept cartoons on 7th grade students' acquiring the concepts in "The Structure and Properties of Matter" chapter. To reach this aim concept cartoons involving students' preconceptions and alternative conceptions about the concepts in the unit were developed. The data of the research…

This paper presents item-analysis data to illustrate how to identify a set of internally consistent test items that differentiate or discriminate among examinees who are highly proficient and nonproficient on the construct of interest. Suggestions for analyzing the quality of test items are offered as well as a pedagogical approach to augment the…

The aim of the study is to investigate the attitudes of prospective science teachers towards the use of problem-based learning methods in the learning of concepts related to the subject of solids, and their opinions on its role in academic success, science process skills and the chemistry course. The study group consists of 83 prospective teachers…

Although the benefits of addressing cognitive, social and affective aspects of learning in order to support conceptual change have been discussed in the literature, there are few studies of such interventions in the normal classroom. This study used a multidimensional conceptual change framework in order to teach five biology and physics topics…

The present study examined data from the 2015 Trends in International Mathematics and Science Study to address cross-cultural differences in 4th grade students' attitudes towards science and how students' sense of school belonging (SSSB) scores were related to attitude towards science. Regression results indicated that SSSB emerged as a…

Australia has seen declining numbers of students choosing mathematics and science subjects in the senior secondary years, running counter to economic projections of an accelerating need for science and mathematics skills. Many students become less engaged with these subjects in the junior secondary years but attitudes such as self-concept, utility…

The 3D visualization program paves the way for the development of virtual reality. This study produces a 3D visualization program in virtual reality to increase high school students' critical thinking skills and scientific attitude. The Research and Development (R&D) method was based on the ADDIE model - analysis, design, develop, implement,…

The purpose of this study is to comparatively investigate the science teaching curricula in Turkey, which have undergone changes four times since the millennium. For this purpose, we carried out a technical and taxonomic examination of the learning outcomes listed in the science curricula that were introduced in 2000, 2005, 2013, and 2017…

This study enhanced the 7E instructional model towards enriching the science inquiry skills of senior high school learners in General Chemistry 1. A total of 136 Grade 12 learners enrolled in the Science, Technology, Engineering, and Mathematics (STEM) strand participated in the study. The study was composed of three phases. In Phase I, the…

Evolution by natural selection is key to understanding life and of considerable practical importance in public health, medicine, biotechnology, and agriculture. "The Next Generation Science Standards" (NGSS) include natural selection among several evolutionary concepts that all third-graders should know. This article explores a novel…

A total of 136 Grade 12 learners enrolled in the Science, Technology, Engineering, and Mathematics (STEM) strand participated in the study. The study was composed of three phases. In Phase I, the…

Making inferences and reasoning with new scientific information is critical for successful performance in biology coursework. Thus, identifying students who are weak in these skills could allow the early provision of additional support and course placement recommendations to help students develop their reasoning abilities, leading to better…

Climate change and the resulting and related environmental and humanitarian outcomes are some of the fundamental challenges of the 21st century. Green chemistry, a relatively recent addition to the chemistry family, aims to reframe chemistry so that chemistry ethically and responsibly attends to its own environmental and human health impacts and…

The COVID-19 pandemic caused widespread disruptions to the educational system in Nebraska and across the world. At the onset of the pandemic in March 2020, schools in Nebraska were forced to replace on-site instruction with virtual instruction. During the 2020-2021 academic year, many students learned online or under hybrid learning formats.…

This paper discusses the effectiveness of the inverted classroom implemented in a pre-university physics classroom on topics of classical mechanics. Inverted classroom moves from traditional lectures to providing students with pre-recorded lectures and other materials such as videos, online quizzes and online exercises to foster independent…
