This study aims to examine the effects of argumentation-supported problem-based learning (AS-PBL) carried out in the Chemistry-II laboratory course on the conceptual understanding of prospective science teachers about "Chemical equilibrium and Le-Chatelie... see more

La realización de experimentos tiene gran importancia en el proceso de aprendizaje de la Química Física, pues los conocimientos teóricos deben ponerse a prueba en la práctica para obtener mejores resultados. La falta de equipamiento y de algunos reactivos... see more

This researh aims to detect the presence of histamine by forming complex compounds of 5-fluorouracil, Mn (II) metal ions and alizarin red S reagents. This type of research is a laboratory experiment. This research was conducted at the Ikip Chemistry Labor... see more

In practical activities, it is necessary to have media that can provide multi-representation explanations, namely macroscopic, microscopic and submicroscopic, especially in qualitative analytical chemistry for group I and II cations. It takes an innovatio... see more

This study introduces a small-scale chemistry (SSC) approach to inquiry-based practicum activities. SSC was introduced to train PCTs' laboratory skills so that they can be creative when teaching in schools in situations where it is not possible to obtain ... see more

Background: Very few studies have covered emotions and performance of high schoolers in the chemistry laboratory in the world. Science teaching should be supported by the use of laboratory practices that allow students to prove theoretical concepts, and t... see more

In this study, student success metrics using a combined lecture/laboratory “atoms-first” approach will be compared to traditional teaching models in which lecture and laboratory are separate courses with separate meeting times. This model was piloted earl... see more

Virtual laboratory is becoming one of the most significant educational technologies due to financial challenges which often required construction of physical laboratories, particularly in educational institutions in developing countries. This paper presen... see more
