Over the past few decades, the photographic process has slowly vanished from chemistry education in most schools. It happened due to vast changes in both technology and legislation. It is, however, helpful in demonstrating several concepts in natural sciences, bringing a bit of art into the subjects, and giving students an opportunity to express…

This study investigates the challenge faced by eighth-grade students at Southern State Middle School in grasping abstract concepts within the domains of physical science, physics, and chemistry. This difficulty is manifested in their poor performance on summative assessments. A comprehensive analysis of state-provided data, in conjunction with…

This study aimed to develop alternative laboratory experiments (ALEs) in Chemistry 8 and evaluate the perceived improvement of the students' basic science process skills after utilizing the material. This employed a mixed method of research. Initially, a self-assessment survey questionnaire was used to determine the basic science process skills of…

How do different components of a learning environment contribute to learning in science? The study examines the contribution of laboratory experiments and computer model explorations to the learning of chemistry through a complex-systems approach. Specifically, junior high-school students' learning of chemistry via four different methods were…

The purpose of this study was to examine the relationship among pre-service science teachers' global scientific literacy and various variables within the scope of the structural equation model. Since the relations among the variables were investigated in the structural model established for this study, correlational research methodology was…

Chemistry curricula in part rely on the use of laboratory demonstrations and experiments. The complex nature of this kind of educational activity has been posing challenges from the very early days of teaching chemistry. As chemistry is an experimental science, one possible approach to make the teaching of this subject more efficient is to use…

The extinguishment of the candle flame in the well-known candle-and-cylinder experiment has been erroneously viewed as caused by the complete consumption of oxygen, for many reasons. To address this misconception scientifically, a series of experiments are carried out to illustrate the phenomenon from a new point of view. Limewater…

Laboratory courses can help students learn in a meaningful way. In the past, students encountered difficulties in chemistry laboratory courses due to limited access to equipment and space for practicing experimental operations. In recent years, virtual laboratories have allowed students to repeatedly practice in order to achieve their experimental…

The present investigation aims to analyze the knowledge levels and chemical representation levels of pre-service primary school teachers (PPSTs) on the experiment of distillation. For this purpose, the cross-sectional survey technique, one of the quantitative research designs was employed. The study was carried out at a Faculty of Education in the…

We report a series of three experiments that introduce students at different stages of their academic preparation to the medical applications of hydrogels for controlled drug delivery and wound healing. The laboratory activity bridges the fundamental concepts of chemistry (acids and bases, equilibria, solvation, and reversible esterification) with…

In contrast to traditional science instruction, which encourages students to memorize facts from textbooks, today's science instruction emphasizes the adoption of scientific process skills by students, as well as the teaching of critical thinking skills. Lebanese Chemistry teachers detected lack in middle school and high school students' critical…

In the past decades, society in general has become strongly diverse. This change also affects schools. As a result, learning groups cannot be seen as homogeneous and taught in this way. One of the challenges is students' linguistic skills. Dealing with different linguistic competencies should not only be a focus of formal education in schools but…

The aim of the research is to assess the effectiveness of Virtual Lab (experimental group) compared to Physical Lab (control group) in the level of Science Process Skill mastery of topic salt experiment. This research also was done to compare the students' level of Science Process Skill mastery by gender and to find interaction effect between…

In natural science education it is important that the macroscopic, submicroscopic and symbolic levels are interconnected in a student's mind. Primary school children have the greatest difficulty in understanding the sub-microscopic, which is outside their experiential framework. This research examines the classroom application of the virtual…

The Case Study Compilation was developed with and for educators to provide examples of practice related to three questions: (1) What does it mean to focus on social-emotional development and the creation of positive learning environments?; (2) How can educators integrate their approaches to social, emotional, and academic development?; and (3)…
