As a representative catabolic reaction that widely exists in nature, anaerobic digestion (AD) exhibits great value regarding the global carbon cycle, renewable energy development, and environmental protection. Such an important biochemical reaction was ignored before and should be introduced into the teaching and textbooks of undergraduate…

This study aimed to examine the views of preservice science teachers on concept map use in a General Chemistry II class. The study was conducted with 47 preservice science teachers. In the study, an interview form grounded on determining their views on concept maps and comprised of open-ended questions, was used as the data collection tool. In…

This study reviewed the green and sustainable chemistry education (GSCE) research that provided training at the tertiary level from 2000 to 2024. The Web of Science and ERIC databases were screened using title and abstract review. In total, 49 studies were analysed. The analysis instrument has two main parts, namely, general characteristics of the…

The examination of students' motivation towards lessons is an important aspect of educational studies. The constructivist approach significantly impacts the improvement of students' motivation. The present study aims to examine the use of the 5E learning model with concept maps to support students' motivation and compare the 5E approach and the…

Learning progressions (LPs) are descriptions of students' growing sophistication in the understanding of a particular construct through a curricular sequence. They are particularly useful for organizing complex constructs for which students do not necessarily connect concepts as taught in different courses. However, they are challenging to…

This study evaluates the use of an open-ended question to determine students' knowledge structure on the topic of galvanic cells. The open-ended question was developed and administered to 163 Grade 10 students who had earlier completed a course on electrochemistry. Students' responses were marked as well as coded on the basis of the fields…

One challenge associated with introducing systems thinking in chemistry classrooms is the increase in content complexity that students face when they engage in this type of approach. Placing core chemical ideas within larger systems has promise, as long as students are not overwhelmed by the added complexity. Although there are many potential…

The aim of present research was to examine the effects of interdisciplinary teaching approach on teaching the topic of proteins. In the research, unequal control group model- one of the quasi-experimental research designs was used. The experimental group included 16 students (8 female and 8 male) whereas the control group included 14 students (6…

Describes the exploratory assessment of strategy for learning redox reactions in High School, which seeks to prevent students from developing memoristic and mechanical skills, in addition to emphasize the experiences of daily life that go unnoticed or unexplained to the student in the classroom and at the same time are able to incorporate the key…

In this paper educators provide a valuable feedback in the use of concept maps in secondary education. More specifically their use in teaching dyslexic students Science. Almost 100 educators replied to an online questionnaire after they studied a set of evaluation sheets provided to them based on concept maps. We will begin with a brief…

We review literature on the teaching and learning of chemical kinetics at both the secondary and tertiary levels. Our aim in doing so is to summarize research literature, synthesize recommendations for future research, and suggest implications for practitioners. Two main bodies of literature emerged from the chemical kinetics education research:…

The "mole" is a fundamental concept in quantitative chemistry, yet research has shown that the mole is one of the most perplexing concepts in the teaching and learning of chemistry. This paper provides a survey of the relevant literature, identifies the necessary components of a sound understanding of the mole concept, and unpacks and…

This work focuses on a possible teaching approach to promote chemistry learning for students during the first two years of technical high school in Italy (age 14-15). Critical thinking skills can be developed by integrating two different curriculum designs, converging in a novel didactic approach, a modified version of the Systemic Approach to…

Many studies suggest that students have difficulties in learning acid-base concepts. This study presents some conflicts in the textbook descriptions of these concepts and proposes these to be the cause of the students' difficulties. This is especially true regarding the description of the relationship among the Arrhenius, Brønsted-Lowry, and Lewis…

This study aims to analyse prospective chemistry teachers' cognitive structure related to the subject of covalent and ionic bonding. Semi-structured interviews were conducted with the participants in order to determine their cognitive structure, and the interviews were audio recorded to prevent the loss of data. The data were transcribed and…
