The activity presented here is about an approximate or order-of-magnitude approach to information technology on the nano level, dealing in particular with the genetic code. Based on "There's Plenty of Room at the Bottom", the famous and visionary paper by Richard Feynman, the activity provides insight into a core concept of nanoscience…

Flame Emission Spectroscopy (FES) is a powerful analytical technique widely used for identifying and quantifying elements in various samples. In this laboratory experiment, undergraduate students were introduced to FES and its significance in analytical chemistry. The experiment aimed to provide students with hands-on experience in constructing…

This paper describes and compares primary school students' perceptions of science learning skills in a teacher-centered approach (TCA) and in inquiry-based science fieldwork (IBSF). This comparison was prompted by primary school students' perceptions of science learning skills, which has recently gained momentum, and the Namibian primary schools'…

The internationalisation of higher education as well as the emergence of evidence for the claim that bi/multilingualism in science should be the norm, not just an option, are conditions that explain the rise in university bilingual science courses. Thus far, however, little is known about how to foster bilingual scientific argumentation in this…

A new perspective on chemistry learning could be the optimal learning moment of view based on flow theory. Optimal learning moments (OLMs) that occur when students experience high levels of interest, challenge, and skill at the same time were investigated in this study. Participants of the study were 47 pre-service science teachers. Data were…

Further analysis of the effectiveness of integrating project-based learning (PjBL) in Invertebrate Zoology courses to improve students' science process skills and conceptual understanding needs to be carried out. This research was aimed to analyze the integration of PjBL in the Invertebrate Zoology course on scientific process skills and…

Fungi mostly reproduce through spores that are adapted for airborne dispersal; hence, fungal spores (and fungi) are found virtually everywhere. Fungi can be "friends or foes." Our friends include fungi used in the food and biotech industries, fungi that contribute to the cycling of carbon and nutrients, and those involved in the…

In upper-secondary chemistry education, the concept of 'Amount of Substance' occupies a central position within the computation framework. However, comprehending this concept often poses a challenge for students. To address this issue, our study aimed to design and implement a computation skills test to assess the varying levels of students'…

This research purposed to test the accuracy of Machine Learning techniques for learner analytics based on SEEEM factors of secondary education students in Thailand's COVID-19. Research volunteer came from secondary education students in Thailand who invited by researcher. The research questionnaire adapted from Computational Thinking Assessment by…

The first step to access information; it is possible to perceive it by hearing, seeing and touching. It is necessary to make sense of this gained knowledge. Therefore, having some basic skills forms the basis of all disciplines. The purpose of this research is to determine skills through activities prepared with an interdisciplinary approach. The…

Most introductory courses in environmental science are large, lecture-style general education classes. North Carolina State University's ES 100 is no exception, enrolling between 200 and 300 students and holding class meetings in the campus cinema. A key underlying learning objective, however, is to teach students that science is the pathway to…

Previous work has identified that recognition from others is an important predictor of students' participation, persistence, and career intentions in physics. However, research has also found a gender bias in peer recognition in which student nominations of strong peers in their physics course disproportionately favor men over women. In this…

A key part of the practice of chemistry is the analysis of chemical composition, including through gravimetric analysis and spectrophotometry. However, the complexity of doing multiple calculations to obtain analytical evidence, such as that required to determine an empirical formula, presents a challenge if such analytical methods are to be…

This study was carried out with the aim of determining the effect of robotic coding education on pre-school children's skills of scientific process. Study group consisted of 30 children aged five who studied in an independent kindergarten connected to Ministry of National Education in Refahiye district of Erzincan province in the first semester of…

When Mentos candies are dropped into a bottle of Diet Coke, a foamy fountain jets out of the beverage container. It has previously been argued that ingredients found in Mentos candies significantly enhance this fountaining effect. Other previous work has demonstrated that the kinetics of foam production can be quantitatively monitored using a…
