Online prelaboratory videos and quizzes were prepared for all experiments in CHEM 231, Organic Chemistry I Laboratory. It was anticipated that watching the videos would help students be better prepared for the laboratory, decrease their anxiety surrounding the laboratory, and increase their understanding of the theories and concepts presented.…

Promoting positive attitudes about science among teachers has important implications for teachers' classroom practice and for their relationship to science as a discipline. In this paper, we report positive shifts in teachers' attitudes about science, as measured by the Colorado Learning Attitudes about Science (CLASS) survey, over the course of…

The science of climate change is a complex subject to teach. Teachers find climate change a challenging topic to teach due to a myriad of reasons. Gayford, 2010 describes some of the challenges teachers face while teaching climate change science as "first, the controversial nature of the topic; second, it does not relate well to the normal…

This paper reports a laboratorial internship included in the Portuguese Science and Technology promotion program "Internships for Young People in Laboratories (Ciência Viva no Laboratório)", which provided high school students an opportunity to approach the reality of scientific and technological research in a higher education…

There has been an increasingly dominant presence of Filipino ESL/EFL lecturers in Thai higher education; yet, few studies explore the intercultural communicative practices between these Filipino lecturers and pre-service teachers in science teacher education. This study examined Thai pre-service science teachers' perceptions of their Filipino…

Recognizing the limitations of the existing frameworks and models applied to estimate the learning loss caused by COVID-19 across the world by different studies, and the urgent need for estimating such loss at the different education levels, this paper, employs the Education Value Chain Analysis ( EVCA) approach as a new paradigm, attempts to…

Qualitative research conducted with 237 pupils from Canada, France, and Morocco, between 10 and 12 years of age, on the setting and functioning of simple electric circuits, demonstrates that similar explanatory systems of the students. For this, we had given them a paper and pencil questionnaire of a sixty minutes duration. The first question was…

The result of additive colors is always fascinating to young students. When we teach this topic to 14- to 16-year-old students, they do not usually notice we use maximum light quantities of red (R), green (G), and blue (B) to obtain yellow, magenta, and cyan colors in order to build the well-known additive color diagram of Fig. 1. But how about…

In our upper-level undergraduate laboratory course in organic chemistry we focus on a research-oriented task in a context-based and problem-based learning approach. The course starts with a preliminary training period where the students learn how to safely and independently perform synthesis and purification procedures and to operate the most…

The article substantiates the necessity of studying the peculiarities of color vision of human in the course "Biophysics" that have been integrated into many types of higher education institutions. It describes the experience of teaching this discipline in a pedagogical higher education institution. The article presents a brief review of…

This study used content analysis to examine the most studied conceptual change factors that influence students' science learning processes and their learning outcomes. The reviewed research included empirical studies published since Posner et al. proposed their conceptual change model 30 years ago (from 1982 to 2011). One hundred sixteen SSCI…

A simple and straightforward synthesis of an ultrastable porous metal-organic framework (MOF) based on copper(II) and a mixed N donor ligand system is described as a laboratory experiment for chemistry undergraduate students. These experiments and the resulting analysis are designed to teach students basic research tools and procedures while…

As a science leader in her school, the author is always looking for new and interesting ways to inspire children in the science, technology, engineering, mathematics (STEM) subjects. Attending several science conferences introduced her to new STEM programs, such as Street Science and fractals. In this article, she shares a couple of the activities…

Pupils' questions can play a powerful role in helping them to develop conceptual understanding, but can also provide a stimulus for teacher learning. This article presents a series of stories that illustrate the challenges of capitalising on pupils' questions, given the complexity of decision-making required in the science classroom and the…

This study aimed at evaluating the science textbook of the third grade primary school in Jordan from the point of view of the teachers who have taught this textbook, in order to find out how suitable and relevant this textbook is to the structure of the curriculum and its guidelines, by trying to answer this question: What is the evaluation of…
