It is widely argued that Nanoscience and Nanotechnology (NST) is going to affect several aspects of our life. Therefore, students need to develop their nanoliteracy to cope with the everyday issues related to NST. Although there is an increasing interest in introducing NST content to primary school students, the theoretical frameworks for…

Special Relativity introduces students to Modern Physics, whose importance in the high school is increasing. Nevertheless its teaching and learning is a critical issue. Different solutions have been developed to overcome the encountered difficulties. In this paper we describe the spacetime globe, a mechanical instrument that allows to experience…

The article introduces a low-cost Arduino sensor into the Young's modulus determination laboratory for physics university students. A stainless steel ruler is used as a cantilever beam. Its free end attached a mass is slightly bent and released to make it oscillate as a simple harmonic motion. The Arduino sensor detects the moving mass's frequency…

A preliminary study showed that Biology learning in the classroom could not encourage the integration of science concepts and Islamic values. The aims of this study are to (1) develop a new learning model that integrates scientific principles and Islamic values, and (2) characterize the RQANI model's validity, practicability, and effectiveness.…

Scientific argumentation as a scientific practice has become an important issue in scientific concept learning. We systematically searched five databases to assess the potential of scientific argumentation to promote multidimensional conceptual change in science education. The systematic literature search and coding of studies were carried out by…

The purpose of this study is to develop and validate an instrument for measuring Chinese Chemistry Teachers' Perceived Self-Efficacy towards Chemistry Core Competencies. Based on the notion of the 2017 Senior High School Chemistry Curriculum Standards, the initial instrument consisted of 20 items in five CCCs as the distinct constructs were…

This article describes a simple way to introduce nanomaterials using the presence of carbon nanodots (CNDs) in widely available food. Budweiser® beer and Coca-Cola®, commercial foods that are commonly accessible, were utilized to demonstrate the optical property of nanoparticles. Specifically, green and violet laser pointers were employed for the…

The falling rod paradox, i.e. the fact that the tip of an almost horizontal rod falls with an acceleration 'higher than g', when the other end is hinged or supported, is a popular physics demonstration. It can be visualized by placing e.g. a coin on the tip of the rod and fixing a cup next to the coin. When the rod is released the free-falling…

Today's high school graduates are required to digest and interpret massive amounts of information related to science. National standards documents in science education promote the development of skills to effectively evaluate the credibility of scientific information, with the goal of producing citizens capable of making scientifically informed…

Measurement is an important concept in school mathematics (Clements, 2003). There are several studies and empirical evidence on students' thinking about geometrical measurement of length, area, and volume (e.g., Barrett et al., 2017; Battista, 2007, 2012; Eames, 2014; Lehrer, Jenkins, & Osana, 1998; Miller, 2013; Outhred & Mitchelmore,…

Growth in the biomedical and biotechnology sectors requires a highly trained and highly skilled workforce to answer the next great scientific questions. Undergraduate laboratory courses incorporating hands-on training based in authentic research position soon-to-be graduates to learn in environments that mirror those of academic, industrial, and…

Nowadays, technologies involving nanoparticles, colloids, sensors, and artificial intelligence are widespread in society, media, and industry. It is thus mandatory to integrate them into the curricula of students enrolled in chemistry and materials science. To this purpose, we designed a simple assay for the detection of glutathione (GSH) using…

Many efforts to reform science educational standards and structure have placed an emphasis on directing learners to communicate about concepts using external representations (ERs). Techniques to develop competencies with ERs often ask learners to develop understanding outside of a physical context while concurrently making connections back to the…

We developed and field-tested an active learning exercise designed to provide biology students with the opportunity to consider key aspects of the nature of science as a method of inquiry, particularly the roles of observation and inference in the development of scientific explanations and how scientists deal with uncertainty. In the activity…

A word association test was used to determine knowledge structures on biochemistry concepts of secondary school chemistry students, aged between 18-19 years. The basic biochemistry concepts related to the topic of Carbohydrates that take place in the International Baccalaureate Diploma Programme curriculum were determined as stimulus words:…
