An interdisciplinary laboratory experiment was designed and carried out on the basis of the photo/electrochromism of N,N'-bis(cysteine)pyromellitic diimide (BCPD), suitable for organic chemistry laboratory I and physical chemistry laboratory II students. In the organic chemistry laboratory, students synthesized BCPD and studied its…

The purpose of this study is to examine the process of conceptual change in which the heat concept has gone through in time and provide an analytical assessment. To this end, problem-based learning groups were formed with 13 sophomore university students. One of these students was selected and interviewed. The interviews were examined using the…

This study investigates the modelling conceptualisation of secondary school students in two situations related to particle dynamics: pendulum's motion and horizontal motion. We performed in-depth clinical interviews with secondary school students (N = 10). Participants' ideas about properties which are not 'given' in empirical observations were…

Students in introductory physics courses encounter harmonics when they study standing waves on strings and in pipes. The Fourier spectrum, which plots amplitude against harmonic number, can describe all periodic tones imaginable. However, most sounds are aperiodic and therefore have additional spectral components. A real-world application that…

The convenient synthesis of dihydroberberine by the reduction of berberine is described as an experiment for an upper-division undergraduate organic chemistry laboratory course. Students obtained up to 74% yield of the desired pure product without the use of chromatographic techniques. The antimicrobial activities of both compounds against…

Biology is an important subject in curriculum. It helps to develop the scientific attitude, scientific temper, logical reasoning, scientific literacy, awareness of environmental issues, and respect about surrounding life among students. Biology textbook content is an authentic source of information for teachers & students. According to the…

Earlier research has shown that students have tremendous difficulties with understanding certain aspects of rolling without slipping, such as the zero-velocity at the contact point and plausibility of application of the law of conservation of mechanical energy despite action of the friction force. The aim of this research was to explore whether…

"Make to Learn Invention Kits" allow students to reconstruct working models of historic inventions. This design case describes the development of a series of "Make to Learn Electric Motor Invention Kits" that spans the time frame from development of the first patented electric motor in the United States to contemporary…

Background: Chi and colleagues have argued that some of the most challenging engineering concepts exhibit properties of emergent systems. However, students often lack a mental framework, or schema, for understanding emergence. Slotta and Chi posited that helping students develop a schema for emergent systems, referred to as schema training, would…

The purpose of this research is to determine the sources of cognitive and metacognitive strategies that 7th-grade students use when studying the "Cell and Divisions" unit that belongs to the field of Biology. In the study, the case study which is one of the qualitative research methods was used. A total of 6 students from 3 different…

Constructing Direct Current (DC) electric circuits is simple and engaging for primary students, but that is not all there is to learning about electricity. Mandatory learning in the Australian Curriculum: Science (ACARA, 2018) expects Year 6 students to explain some of the processes underlying electric circuits. The abstract nature of key…

A teaching approach based on the Biggs and Collis SOLO taxonomy is described. Lessons were planned using the SOLO taxonomy to communicate how students could demonstrate increasing complexity of response to scientific questions. Consideration is given to extending the use of the SOLO taxonomy to create a relational curriculum, which may be useful…

The aims of teaching have evolved along with the society in which we live, from a teaching based in memory to a one that teaches to reason, in order to adapt to the accelerated rate of change imposed by the application of scientific discoveries in our society. We have a society in continuous learning, which requires the ability to reason in order…

Evolutionary evidence is important scientific background for appreciating the theory of evolution. We describe a STEAM-based lesson plan that uses paleontological drawings and a modern evolutionary database to explore and understand fossil, morphological, and molecular evidence. Together, with a focus on arthropods and the Cambrian explosion,…

Chemistry is traditionally perceived as difficult to comprehend. Its mastery requires that a variety of concepts be linked to form an organized knowledge system. The connections need to be made not only between the concepts associated with the macroscopic level of the chemistry triplet but also between the submicroscopic and symbolic levels. Many…
