Collaboration among students is fundamental for knowledge building and competency development. Nonetheless, the effectiveness of student collaboration depends on the extent that these interactions take place under conditions that favor commitment, trust, and decision making among those who interact. The worldwide pandemic due to COVID-19 and the…

This sixth-form chemistry activity describes how students can use acid-base titrimetry to investigate how adding salt to the aqueous phase may change the value of the partition coefficient of an organic acid between water and 2-methylpropan-1-ol. While the presence of lithium chloride and sodium chloride increases the value of the partition…

Balanced science was a possible answer to a perceived need in England, Wales and Northern Ireland for students to study the three major science subjects up to age 16 without taking too large a proportion of curriculum time. Experience has shown that it is not a simple problem to solve, and this article describes various attempts going back several…

There is, broadly speaking, an agreement within the international science education community that comprehension of the nature of science (NOS) should be a key element in the scientific literacy of citizens. During the last few decades, several didactic approaches have emerged concerning what and how to teach NOS. Also, one of the basic objectives…

The problem of the current research lies in the need to integrate some requirements of the sustainable development (SD) in secondary school chemistry curriculum. The research specifically seeks to answer the following question: What "requirements of sustainable development" should be taught in the secondary school chemistry curriculum in…

This paper describes a responsive, digital periodic table that has been specifically designed as a visual aid for high school or college chemistry classrooms and lecture halls. The periodic table runs in a web browser and can therefore be used in any classroom that has a digital projector and screen. It features click-to-highlight table cells that…

The present study aimed to explore the availability and utilization of a science laboratory for the teaching and learning of science. This study was a joint collaboration with India's Ministry of Human Resource Development, the Government of India, and the National Council of Educational Research and Training. The study adopted descriptive survey…

Students often have difficulties comprehending situations in which wave characteristics of light are manifested. After teaching wave optics, we studied the level of understanding of reflective diffraction of light with a group of secondary school students, and the phenomenon of diffraction in general. We analysed the possibility of using…

This study is aimed at exploring ninth-grade Bhutanese students' views of nature of science (NOS). A total of 389 students from middle secondary and higher secondary schools from the eastern, western, southern and central regions of Bhutan took part in this study. To generate a representative population, a stratified random sampling technique was…

In this paper we present a novel approach to teach kinetic energy as an observable and measurable concept. The fundamental principles have been outlined for gravitational potential energy in an earlier work, that we extend here. By accelerating or decelerating bodies with springs we begin, in a first step, with a direct comparison method for…

Teaching the concept of pH buffers is considered to be important both in the final high-school years and at the early undergraduate level. Here, we propose the use of pH-log C diagrams to investigate the properties of pH buffers. This graphical approach is extremely simple to employ because it only requires drawing a simple square that can then be…

Purpose: Self-efficacy plays a crucial role in achievement; and thus, it is important to determine the factors affecting self-efficacy. It has been known that one's reflections and evaluations of their thoughts, emotions, and behaviors are of paramount importance in the development of self-efficacy. Therefore, the aim of this study was to…

The main aim of this study is to compare the information about meiosis and mitosis divisions of secondary school students with different methods. The mixed method was used in the research. In the mixed method, it is aimed to close the deficiencies in the solution of the research problems with both qualitative and quantitative data. Homogeneous…

This paper aims to examine how science teachers adapted their practices to the context of the COVID-19 pandemic and what they learned during the period of confinement. The participants are fifteen science teachers who currently collaborate on a STEM research project. To collect the data, we used two techniques (individual interviews and teachers'…

The study determined the extent of the special science curriculum implementation in public secondary schools in the Division of Rizal for the school year 2022-2023. This research employed a descriptive survey design to determine the assessment of the teachers and school heads on the program's implementation. The findings revealed a commendable…
