We use the Survey of Thermodynamic Processes and First and Second Laws-Long (STPFaSL-Long), a research-based survey instrument with 78 items at the level of introductory physics, to investigate introductory and advanced students' difficulties with entropy and the second law of thermodynamics. We present an analysis of data from 12 different…

Students in high school tend to find genetics difficult to learn because it requires some crosslinked knowledge about subjects like genes, proteins, cells, tissues as well as organs and systems. It also becomes more difficult to connect and explain concepts such as the gene expression at the level of the cell to conceptualize the effect of the…

Although there has been extensive research on students' understanding of the particulate nature of matter (PNM), there is still a lack of research on contexts that can be used to teach this challenging topic. In a previous design-based research study, the authors developed a teaching-learning sequence (TLS) on the PNM in the context of crystal…

The flipped classroom teaching model has been widely used in anatomy education to embrace a blended learning strategy. However, the impact that a continuous flipped classroom teaching model exerts on student learning of human topographic anatomy remains unclear. To address this question, student learning experience and performance were compared…

A wide array of conceptual change strategies attempted to address students' persistent alternative conceptions, yet there remained ubiquitous struggles of teachers teaching abstract and highly contentious science concepts. This study investigated the effectiveness of the novel Conceptual Change Framework of Instruction (CCFI) in teaching eclipses…

The alternative conceptions that students hold put a brake on subsequent meaningful learning, and therefore, the identification of these wrong ideas is crucial for effective teaching and academic success. Undergraduate STEM students often perceive Chemical Thermodynamics as a difficult subject, in which entropy has been pointed out as a threshold…

Learning in a virtual environment has been found to foster students' affective responses, indicating the importance of exploring the factors which affect students' learning when engaged in a virtual game. This study aimed to explore the relationships among students' epistemic curiosity, situational interest, and learning engagement in an…

This study focused on addressing underperformance in chemistry in Anglophone West African countries. The main purpose of the study was to determine if factors such as gender, school location and ownership impact students' perception of the difficulty of chemistry concepts and to suggest how these difficult concepts can be made easy to learn from…

Biology is a subject that contains of many difficult concepts to study. This study aimed to identify Biology topics taught in Senior High School (SHS) which were considered as difficult materials by undergraduate students. The data were gathered by means of a web-based survey from 198 Biology students of 25 universities and 51 Biology education…

Even after research-based instruction, students who demonstrate the ability to assemble relevant conceptual knowledge on one physics question may have difficulty assembling that same knowledge on a closely related problem. Recent research has suggested that reflexive, bottom-up reasoning processes seemingly unrelated to the physics concepts…

Mole, molar mass and the Avogadro number are used constantly to measure the amount of substance in chemical changes. However, students have difficulty in understanding these concepts because they are not familiar with measuring very small amounts of matter that cannot be seen and weighed in daily life, like atoms. The mole concept was developed to…

This study explored the Rwandan secondary students' opinions on learning biochemistry concepts covered in the Rwandan advanced level of secondary school biology curriculum, and the reasons behind the difficulty of the concepts. In this research, sequential exploratory mixed-method designs were adopted. The sample comprised 195 secondary school…

Organic qualitative analysis is one of the challenging chemical concepts in students learning of chemistry. The West African Examinations Council chemistry chief examiners for years, have lamented on students' poor performance in organic qualitative analysis at the senior high school level. This study, therefore, investigated chemistry students'…

Background/purpose: Understanding gifted students' perceptions by means of metaphors, carefully examining and interpreting them may help to guide the organization of training programs and the differentiation of educational content for gifted students. This study aims to reveal the perceptions of gifted students regarding science and mathematics…

This report describes an activity that helps organic chemistry students to better understand organic molecules as 3-dimensional objects. To accomplish this goal, the activity employs a unique three-way combination of analyzing computer-generated 3-dimensional renditions of open access X-ray crystallography data, building physical 3-dimensional…
