Organic chemistry is challenging for novices as it involves a large quantity of organic reactions. Effective learning requires not only profound theoretical knowledge but also the ability to reason about causal mechanisms. This study investigated pre-service chemistry teachers' mechanistic reasoning and the implicit cognitive process. Participants…

The sounds of birds form the outdoor playlist of our lives. Birds appeal to the public, in part because of the wide variety of interesting sounds they make. This popularity has led to a long history of amateur participation in ornithology, which has recently produced rapid increases in freely available online databases with hundreds of thousands…

A systematic review of Threshold Concepts provides a thorough and structured analysis of the existing literature related to these essential and transforming concepts in education. Threshold Concepts represent ideas or knowledge that, once understood, allow the student to access deeper levels of understanding of a discipline. These concepts are…

Modelling roles of mathematics in physics has proved to be a difficult task, with previous models of the interplay between the two disciplines mainly focusing on mathematical modelling and problem solving. However, to convey a realistic view of physics as a field of science to our students, we need to do more than train them to become fluent in…

This study aimed to investigate the following questions: Does the use of thinking maps and semantic mapping during explicit vocabulary instruction affect content specific science vocabulary knowledge and comprehension in fourth grade students? and What are student perceptions of using thinking maps and semantic maps to learn new vocabulary? To…

Background: Blended mathematical sensemaking in science ("Math-Sci sensemaking") involves deep conceptual understanding of quantitative relationships describing scientific phenomena and has been studied in various disciplines. However, no unified characterization of blended Math-Sci sensemaking exists. Results: We developed a theoretical…

Load reduction instruction (LRI) is an instructional approach designed to manage the cognitive load on students as they learn complex learning materials. According to Cognitive Load Theory, complex learning is associated with high cognitive load and when not effectively managed, could impede learning. Inquiry-based learning with hands-on…

Cognitive load studies are mostly centered on information on perceived cognitive load. Single-item subjective rating scales are the dominant measurement practice to investigate overall cognitive load. Usually, either invested mental effort or perceived task difficulty is used as an overall cognitive load measure. However, the extent to which the…

With the release of Framework for K-12 Science Education (National Research Council, 2012) and Next Generation Science Standards (2013) documents, engineering was integrated into science teaching. With that emphasis, teachers require to incorporate engineering practices and nature of engineering into their practice. Most of the attention has been…

Students need a strong understanding of how to represent chemical compounds in order to succeed in organic chemistry. This project set out to gain a better understanding of students' difficulties with symbolic representations, by identifying the specific errors associated with drawing wedge-dash structures. The focus was on how students…

Educators cannot overlook the affect's potential for students' educational success. In this study, affective analogies are proposed as a didactic resource to foster students' affect for chemistry learning and positive attitudes towards the physics-chemistry subject. To examine the influence of the affective analogies on it, we grouped contents of…

Educational animation, recognized for its potential accessibility and engaging qualities, has become increasingly prevalent in classroom instruction. However, not all educational animations exhibit high quality or significantly enhance learning outcomes. This study addresses the need for optimizing educational animation design to enhance student…

This study explored the impact of oxidation-reduction reaction problem difficulty on university students' cognitive load using event-related potentials (ERPs). Forty-eight balanced low and high difficulty problems were designed. Fifteen undergraduate students majoring in chemistry (8 females and 7 males) participated in the study. Results…

In this study, I documented, analyzed, and compared the thought processes of six high school science teachers during twenty minutes of planning for NGSS-aligned instruction. Teachers' thoughts were captured using a virtual revisit think-aloud protocol and their thoughts were analyzed and compared using a novel tool called a thinking web. A…

Understanding how and why science works is a major goal of science education. The aim of this article is to analyze the influence of a research experience in real science contexts, in the thinking and practice of preservice elementary teachers regarding inquiry and nature of science teaching. An in-depth case study which highlights the affordances…
