This research investigated the relationships between pre-service chemistry teachers' science process skills and critical thinking skills. The sample consisted of 146 pre-service chemistry teachers (47 males, 99 females) drawn from an Indonesian public university in the first semester of 2017/2018 academic year. Through a quantitative correlational…

Because school laboratory activities obtained by pre-service teachers tend to use cookbook experiments, this study focused on redesigning chemistry laboratory activities at the university level from cookbook experiments to inquiry-based Science, Environment, Technology, and Society (SETS) approach, and analyzing pre-service chemistry teachers'…

The authors developed a lesson for teachers to integrate chemistry and culinary arts, providing students with an opportunity to participate in three-dimensional learning, engage in science and engineering practices, and apply disciplinary core content and crosscutting concepts (Krajcik et al. 2014). The project involved five classes: three…

As 2019 is the 150th anniversary of the Mendeleev's Periodic Table, UNESCO has proclaimed this year the International Year of the Periodic Table (IYPT2019). One of the most important steps in the evolution of the Periodic Table is the concept of atomic number, established by Moseley. In this article, his work is commented on, and the emission of…

Students today are increasingly engaged in the use of digital information and communication technologies. The Internet continues to grow and more and more young people are using it worldwide. Educational practices, however, have been slow to adapt to the corresponding developments. For example, Internet forums are generally ignored in most…

The number of science education research papers has been rapidly rising in recent years. This number has been particularly influenced by researchers from non-English speaking countries who contribute to the field. With this number of papers, literature reviews gain in importance as they help researchers more easily orient themselves in problem…

This study focuses on the design of play-based learning activities for chemistry in preschool. Viewing chemistry as a part of our past and present culture instead of as a subject, provides the backdrop for a more holistic approach to chemistry within this specific environment. A cultural-historical perspective, together with scaffolding, emergent…

Changing majors or dropping out are of great concern to universities worldwide, but the role of learning approaches in terms of students' persistence has not been previously studied. Changing majors, especially in chemistry, is a severe problem in Finland. Here, learning approach data were collected with the ChemApproach questionnaire from 733…

The ready availability of interactive platforms has produced a new generation of students able to utilize computer-based learning tools with ease and comfort. The potential to better "explore by yourself" the lecture material permits students to have an enhanced learning experience and stimulates them to tinker with equation parameters…

In this study we aimed to analyse the effects of the Instructional Curriculum based on Cooperative Learning (ICBCL) prepared for the subjects, the orders of electrons and chemical properties, chemical bonds, compounds and their formulas, and mixtures on 7th grade learners' learning achievements, motivations to learn science, and their attitudes…

This laboratory experiment, designed for undergraduate nonmajors or advanced high school students, attempts to demystify the technique of spectrophotometry by utilizing a hands-on, real-world approach. Modification of the reaction for the formation of Fe[(bpy)[subscript 3]][subscript 2+] allows students to interact with vitamin C, a compound with…

Sustainable practices in process chemistry are highlighted by a novel, 9 week team project of 8-12 students, in collaboration with AstraZeneca chemists, in an organic chemistry laboratory. Students synthesize the antiulcer medicine esomeprazole, which involves the asymmetric oxidation of pyrmetazole. To provide insight into the modern process…

Visual representations are prevalent in STEM instruction. To benefit from visuals, students need representational competencies that enable them to see meaningful information. Most research has focused on explicit conceptual representational competencies, but implicit perceptual competencies might also allow students to efficiently see meaningful…

In recent years, nanotechnology has been one of the major subjects of scientific and technological research. Currently, several applications of nanotechnologies are already available on the market. Particularly relevant are the fields of new materials and sensors, which have excellent potential future applications in the biomedical field. This…

In this work, two exercises are described that are designed to teach students about the evolution and behavior of the electronic bands of graphene and bilayer graphene. These exercises involve performing extended Hückel molecular orbital theory calculations on polyacenes and polycyclic aromatic hydrocarbons. In the first exercise, students…
