Science instruction is a critical aspect of early learning. Teachers can support young children's learning about scientific concepts through the use of the Universal Design for Learning (UDL) framework, which is a proactive approach to instructional planning that helps ensure success for all learners. This teaching techniques article offers…

Inquiry-based learning can be an effective approach when students are provided with sufficient guidance. However, there is an ongoing debate among practitioners about the nature, type, and level of such guidance. This study investigated the effects on middle school students' (N = 116) conceptual knowledge and inquiry skills acquisition of…

This paper examines the roles of multimodality and thematic patterns in the teaching of the particle model of matter. Although the particle model is a fundamental topic in science education, there is no consensus on (1) whether or not the model should be introduced in early grades and (2) how to introduce the model to students for the very first…

The purpose of this study was to identify and describe the improvement of students' scientific process skills and scientific creativity. This type of research is quantitative descriptive research with thirty students of Class VII of the junior high school Negeri 12 with the main subjects of temperature and heat. The results showed that the…

The glowing discharges of plasma obtained by introducing direct current high voltages between two electrodes in a chamber that contains a low pressure gas produces a spectacular effect that makes it attractive to be used as a laboratory experiment for students. Setting up this experiment is however costly and has crucial safety issues to be…

Cognitive activation is one of the central quality characteristics of teaching. Studies which analyzed cognitive activation in science instruction and its influence on the achievement and the interest of students, took most of the times place in higher grades. Since scientific thinking can be taught at a very early stage and, in particular,…

This paper investigates differences in students having various scores when designing controlled experiments in two types of scientific inquiry tasks (a fair test and an exhaustive test). We measure temporal features of preparation time and execution time, which reflect respectively the process of question understanding and answer planning and that…

A versatile and portable apparatus was developed to demonstrate exciting visual displays of catalytic phenomena that introduce basic concepts in catalysis, renewable energy, and chemical safety, in order to pique scientific curiosity in a variety of audiences including middle and high school students, undergraduate and graduate students, and the…

The aim of this study is to reveal the effect of using virtual lab application in science teaching on students' academic achievement and students' views on virtual lab application. The study group of the research consists of 62 students studying in the 8th grade of a secondary school in Antalya in the 2019-2020 academic years. Mixed method design…

The first case of coronavirus disease 2019 in Colombia was detected on March 6, 2020. Subsequently, schools, colleges, and universities were closed on March 26, which forced a massive migration to virtual education and impacted laboratory-based teaching courses. The teaching of biochemistry requires an experimental component that virtual…

A novel technology that employs computer vision (CV) to carry out an automatic titration experiment is presented. The experiment is designed to facilitate understanding of the basics of the CV technology and its application in chemistry among undergraduate students. The standard chemical procedure of titration has been chosen, since it is…

In this work we present a simple and low-cost setup to illustrate the dependence of the behaviour of a standing wave in a guitar string with the initial conditions. To do so, we impose two kinds of initial conditions; in the first instance, the initial shape of the string is varied. Secondly, different nodes are imposed on the string. This…

In this teaching laboratory, the students are directed in an exercise that involves designing and performing an experiment to determine estrogen's role in regulating delayed implantation (diapause) in female rats. To encourage active participation by the students, a discussion question is provided before the laboratory exercise in which each…

A diagnostic study is presented of the prior experiences, conceptions, and pedagogical valuations of prospective primary teachers (PPTs) about experimental activities (ExA's) in science education. The participants were 121 PPTs who, in small teams, responded to various questions related to ExA. Their responses were analysed interpretively with…

Magnetic iron oxide nanoparticles were synthesized and stabilized using ammonium cations or poly(vinyl alcohol) to produce amazing materials such as safer aqueous ferrofluids, ferrogels, ferromagnetic inks, plastics, and nanopowders illustrating how versatile materials can be produced just by simple modifications. The synthesis is fast, reliable,…
