The research aim was to identify the effect of revising the thematic unit "Changes in Chemical Reactions" using IBSE (based on confirmation inquiry) in the 8th grade of secondary school. This thematic unit is taught in chemistry lessons in the 2nd term of the 7th grade. A set of activities verified by a piece of pilot research was used…

Background: In Slovakia, no relevant information is available about the scientific literacy levels achieved by secondary school students. Purpose: The objective of the research was to identify the levels of scientific literacy among students in the last year of grammar school and examine to what extent this determined the subject chosen for a…

We describe the conceptualization, design, development, validation, and testing of a summative instrument that measures high school students' ability to analyze and evaluate data, construct scientific explanations, and formulate scientific arguments in biology and chemistry disciplinary contexts. Data from 1,405 students were analyzed to evaluate…

Chemistry is an experimental discipline that uses experimentation as one of its most important research methods. Laboratory work and other practical work are therefore also essential in chemistry lessons. Chemistry demonstrations are used by teachers as an educational approach that can increase students' interest in chemistry and motivate them to…

The COVID-19 lockout situation affected people all over the world. Despite all of the disadvantages, this situation offered new experiences and perspectives and pushed education advances forward as never before. Something that seemed to be unreal became a worldwide reality within a few days. Instructors of all subjects at all educational levels…

The coronavirus disease 2019 (COVID-19) pandemic is being considered one of the most challenging global crises that the world has experienced in recent history, causing ripple effects and major disruption across all aspects of our daily lives, especially education. Many countries around the world, including Jordan, have instituted shutdown of…

Just-in-Time Teaching, collaborative learning, and specifications grading were used for Organic Chemistry 2 during the switch to remote instruction caused by the COVID-19 pandemic during Spring 2020. Relatively minor adjustments to the face-to-face instructional plan enabled remote instruction and assessment of all planned learning objectives to…

This paper summarizes a project seminar in analytical chemistry that includes a method comparison approach and collaborative learning. In this project seminar, 12 students worked in four groups, each of which focused on one method for quantitative element analysis, including flame atomic absorption spectroscopy, inductively coupled plasma mass…

On the basis of the results of two prior studies at the US Naval Academy (USNA), which described the choice of study resources and the self-reported learning approaches of students of differing achievement levels, the current investigation examines how students of differing achievement levels in general chemistry actually solve multiple-choice…

This paper describes a service-learning course in Chemistry Honours at Rhodes University in South Africa. Students visit two schools in different settings, where they present a lecture-demonstration, entitled 'A Pollutant's Tale', and two hands-on experiments to school learners. The students are assessed on their learnings as seen through their…

This research was conducted to facilitate the conceptual understanding of the solutions that contain abstract concepts and not to understand easily. The aim of this research is to determine the effect of applied methods on the achievement level of prospective science teachers and conceptual understanding level at the particulate nature of matter…

This study is a detailed look at the level of understanding of fundamental ideas about blackbody radiation (BBR) among physics teachers. The aim is to explore associations and ideas that teachers have regarding blackbody radiation: a concept used routinely in physics and chemistry, which is necessary to understand fundamentals of quantum physics.…

Little scholarly investigation of chemistry outreach carried out by undergraduate students in schools and communities has occurred despite widespread practice and monetary investment by large national and international organizations. This study provides the first investigation of these fairly uncharted waters by characterizing expected outcomes of…

This article examines how emergent bilingual students used gestures in science class, and the consequences of students' gestures when their language repertoire limited their possibilities to express themselves. The study derived from observations in two science classes in Sweden. In the first class, 3rd grade students (9-10 years old) were…

In a university third-year instrumental chemistry laboratory students build a laser based polarimeter for determining light scattering with commercially available optical components used in modern optics research laboratories. During this laboratory experiment, students learn that solutions containing molecules which scatter light also influence…
