This laboratory experiment demonstrates the important utility of transition-metal complexes as catalysts in the addition reaction of carbon tetrabromide (CBr ) to select alkenes. This application offers students the opportunity to understand why transition-metal complexes are worth synthesizing. The experiment builds on fundamental theories…

A five-day discovery-based summer workshop for incoming ninth graders was designed and conducted at the University of Cincinnati (UC). The idea was to have an inquiry-based, research-driven laboratory experience where students were provided with a mentor who encouraged creativity and inquisitiveness. Over a period of three years, 33 students…

A laboratory experiment was developed that connects the interpretation of computer-generated models to the self-assembly of macrocycles. Students compare the reactions of terephthalaldehyde and isophthalaldehyde by reacting each with (R,R)-(-)-1,2-diaminocyclohexane. These isomeric systems serve as the foundation for a discussion about the impact…

This work describes the design, building, and testing of miniature, low-cost LED-LDR colorimeters for absorption-spectrophotometry experiments. It also describes using these colorimeters for simplified context-based-learning (CBL) activities in school teaching laboratories and for public-engagement events. The colorimeters are simple and robust,…

This study aims to explore the views of pre-service chemistry teachers on the nature of science and technology. Pre-service chemistry teachers' view of nature of science and technology (VNOST) is very important to help their students later in understanding the concepts of science. This research is the initial stage in didactical design research…

Educational Technology is an applied study which aims at maximizing learning by making use of the scientific and technological method and concepts developed in other social service. "Educational technology is the application of scientific knowledge about learning and conditions learning to improve the effectiveness and efficiency of teaching…

An overview of the relationship between educational research and teaching chemistry is presented, covering the opportunity areas between production and science popularization (dissemination of scientific knowledge). Knowledge apprehension and appropriation are also discussed in the educational context of UNAM, in Facultad de Estudios Superiores…

Currently there are two primary methods of recording flipped classroom videos: (1) using the white board and (2) screencasting a PowerPoint presentation. Both methods have several disadvantages. In the former, the presenter's body obscures the content. Both methods lack an element of human interaction between the viewers and presenter and require…

The science laboratory learning environment has been a distinctive area in science education since the 19th century. Unfortunately, students are generally not aware of what science instructors expect from laboratory experiences, and far too often, the undergraduate science laboratory curriculum lacks explicit, well-defined goals. Science…

This study investigates the effect of inquiry-based learning with socio-scientific issues on students' higher-order thinking skills in the first year based on chemistry topics. This study used a quasi-experiment design as a method. A sample of 96 students in three classes was selected and was divided into two groups. An experimental group used two…

Purpose: In Malaysia, research indicates that there is an interest amongst the stakeholders, namely, administrators and academicians to be engaged in education for sustainable development (SD), but it is rarely implemented as a part of the higher education curriculum due to various barriers. This paper aims to develop a framework for integrating…

The aim of this study was to determine the attitudes towards laboratory skills and chemistry laboratory anxieties of pre-service science teachers who were currently registered to general chemistry laboratory course and who had taken this course previously. To evaluate candidates' attitudes and anxieties in line with this purpose, they were…

STEAM (Science, Technology, Engineering, Art, Mathematics) learning is design to promote student's interest in learning chemistry. Integration STEAM into chemistry learning is often seen as a challenge, such as not familiar and lack of knowledge on STEAM in chemistry. Coping, for this reason, a web-based STEAM online platform was designed. This…

During the Spring 2020 semester, many institutions abruptly transitioned their courses from face-to-face instruction to remote learning in response to the COVID-19 pandemic. To address the unique challenges posed by the remote teaching and learning modality, our department used mobile technology to adapt empirically validated instructional…

Plants encounter several different threats that affect their well-being during the spring. With chemistry, plants may defend themselves from, for example, excess UV-radiation and herbivores. The defense compounds between plant species vary, which makes it possible to utilize chemistry in identifying the plant species. In this laboratory…
