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…

Background: Cognitive and linguistic factors have been incorporated into models to explain reading comprehension beyond classical models of reading. This study explores the contribution of executive functions, mainly domain-general and reading-specific cognitive flexibility, in reading comprehension of science texts in monolingual Spanish speaking…

Aim/Purpose: This study aims to analyze the cognitive load experienced by secondary school students in Biology within m-learning environments and its impact on learning performance. Background: Cognitive load has become a critical issue that schools need to address to ensure students can excel in their learning without being overwhelmed. While…

Retrieval-based learning, using tests for content review, frequently proves more effective for knowledge retention compared to alternative methods. Extensive research has explored this with older students, often in contrast to more passive techniques like rereading or note rewriting, typically focusing on vocabulary content, in non-classroom…

Genetics is an area that is increasingly important in people's daily lives. Despite this, its teaching/learning is among the most challenging topics in biology. Several instruments were created over a number of years to ascertain the quality of teaching and learning genetics. In our study, we created a specific instrument to investigate Mendelian…

The performance in biology at the secondary level has not been as good as expected. This has been a matter of concern. Thus, there has been a continuous focus on exploring newer innovative learner-centered and friendly instructional strategies to enhance understanding and retention in biology. This study, therefore, determined the effects of…

This study aimed to determine the cognitive structures of preservice primary school teachers for basic biology concepts using Word Association Test (WAT). The study group consists of 50 preservice teachers studying in a university in Western Black Sea Region in Turkey. Four separate cut-off points were determined and analysed. Organ, living…

Over the past few decades, researchers have focused on the lack of conceptual understanding of mole concept because it is considered to be difficult for students globally. Due to its abstract and mathematical nature, chemistry teachers tend to use algorithmic teaching strategies to provide learning experiences for students, resulting in…

Chemical equilibrium is so important domain knowledge in chemistry that the corresponding organisation of concepts in students has been an interesting but unsolved issue. A deeper understanding of how students organise the relevant concepts in long-term memory is beneficial to develop more targeted teaching practices. This research utilized the…

Learners underperform in stoichiometry as they lack conceptual reasoning of the underlying concepts and the ability to solve stoichiometric problems. Therefore, it was necessary to determine if there is a statistical correlation between problem-solving skills and conceptual reasoning in stoichiometry and if so, whether one can significantly…

This study aims to reveal the problems faced by a dyslexic student in learning science and determine what can be considered an effective science teaching method for this kind of learner. The case study design was used, and the study was conducted with a 7th-grade dyslexic female student. This study used observations and a semi-structured interview…

The aim of the present research is to explain how the heuristics utilized by the students in a multiple choice examination on the general chemistry subject of "chemical bonding theories and molecular structures" caused biases on intuitive judgment and decision making processes, using the three characteristics of associative memory…

Combinations of text and different types of pictures are commonplace in biology as in science in general. The single representations (i.e., text, picture) constituting a text-picture combination may contain redundant or complementary information. The ability to identify and integrate information in different kinds of text-picture combinations is…

Children often learn information in a context that is vastly different to the one in which they are asked to recall or use that information. Despite this, little is known about the effect of context change on children's recall of educational information. Here, 197 5- and 6-year-olds were taught the same interactive lesson in their classroom or on…

Virtual laboratory simulations are commercially available to train students; these creative resources are available to complete remotely without traditional time and safety restrictions of laboratory-based practical classes. We introduced a Health and Safety virtual laboratory simulation to a core large first-year science module. Having surveyed…
