Researchers from Loughborough University in the UK presented an interesting case in which they applied Richard Mayer's principles of multimedia learning to create mathematics teaching materials for young children (7-9 years old) and middle school children (11-14 years old). Their work focuses on the use of multimedia elements to improve the perception and assimilation of mathematical concepts. The application of Mayer's theories improves learning, making it more interactive and accessible to children, which, in turn, contributes to the formation of sustainable knowledge and skills in mathematics.

The researchers developed and presented teaching materials based on the principles of multimedia learning proposed by Richard Mayer. These principles are formed on the basis of his theory, as well as Allan Paivio's dual coding theory and John Sweller's cognitive load theory. The main goal of these principles is to facilitate the process of perceiving new material for students, minimizing the overload of working memory and attention. Thus, the implementation of these approaches promotes more effective learning and assimilation of information, which is especially important in the modern educational process.

Although the principles of cognitive science proposed by Mayer seem useful and logically formulated, their application in the field of instructional design proves difficult. Some of these principles raise reasonable doubts about their effectiveness. The authors of the article "Problems of Applying Cognitive Science Principles in Developing a School Mathematics Curriculum" share their experience and observations, which are based on professional impressions. In the future, they plan to test their findings on schoolchildren to evaluate the practical applicability of these principles in the educational process.

This article examines key aspects related to the topic. The authors analyze the main problems and propose effective solutions. A key point is the emphasis on the research's significance for the further development of this field. The role of modern technologies in process optimization is also emphasized. The article includes examples of successful practices, which allows for a better understanding of the proposed ideas. In the conclusion, the authors draw conclusions about prospects and recommendations for further action.

Coherence Can Interfere with Clarity, and Vice Versa

The creators of the program faced an important dilemma regarding the principle of coherence. This principle states that learning materials should contain only what is necessary to achieve educational goals, without unnecessary elements. For example, materials should not contain images that carry no semantic load and are added only for aesthetic effect. Such elements can distract attention and occupy limited working memory resources, which hinders the learning process. Optimizing the content of educational materials with this principle in mind promotes more effective knowledge acquisition.

To ensure consistency, the program's authors sought to minimize cognitive load by eliminating redundant details, unnecessary design elements, and inessential examples from the content. The materials were designed in a unified style: a minimum of extraneous elements, user-friendly fonts, a simple color scheme, and sufficient white space were used. This avoids the feeling of information overload on the page and promotes better comprehension of the material.

The assignment texts were written in simple and accessible language. The use of officialese and complex terminology was excluded to ensure easy perception of the information. We strived to make each idea clear and concise, ensuring clarity and ease of assimilation.

Conciseness of the text can lead to a number of problems. Despite its appeal, brevity can hinder understanding of the essence of the information and reduce its informativeness. Readers may not get a full understanding of the topic, which negatively impacts the perception and assimilation of the material. Therefore, it's important to find a balance between succinctly expressed ideas and sufficient depth of presentation to ensure effective engagement with the audience. Brevity can sometimes reduce clarity, while more detailed explanations can enhance it. However, such explanations often lead to long text blocks. In situations where there is a conflict between brevity and clarity, we prefer clarity and precision. This is especially important for understanding many mathematical concepts and definitions. Research shows that clear language promotes better retention and increases learning effectiveness.

In the section on statistics, the authors noted that a definition that is too laconic makes it difficult to clearly present the topic and omits important details necessary for a full understanding.

In the section on fractions, the lengthy definition proved redundant, as it lacked a clear meaning and was not part of the learning objectives. In each specific case, it was necessary to carefully determine when more detailed exposition was required to achieve complete clarity, and when brevity was more appropriate.

The issue with images is also relevant. The principle of consistency suggests avoiding an excessive number of illustrations—for example, for a problem about a train, a picture of a train may be redundant. However, the developers noted that in some cases, visual elements are necessary. For example, for children learning English as a second language, familiarizing themselves with certain words can be difficult, even if it is a simple word like "train." Visual cues in such situations can significantly facilitate comprehension.

The authors presented a head rotation problem, examining the ability of barn owls (a species of owl) to rotate their heads more than 270 degrees. For clarity, they illustrated the problem with an image of a barn owl. This solution is also intended to help native English speakers better understand the "angle of rotation" involved. As a result, such visual accompaniment helps to reduce the cognitive load and facilitates the perception of the material.

Differentiating Context from Engaging Details

Textbooks and learning materials provide more than just a collection of facts; they contain meaningful and engaging information that promotes effective learning. According to cognitive load theory and the principles of multimedia learning, it is important to avoid excessive stimulation, which can overload learners with irrelevant information. Figuring out what is truly useful and relevant can sometimes be challenging. While interesting facts can spark curiosity, they can also distract from the main ideas and make it difficult to remember. Such facts are often referred to as engaging or enticing details. Therefore, when creating educational materials, it is necessary to strive for an optimal balance between interest and information content to ensure deep and productive knowledge acquisition.

The developers of the mathematics curriculum arrived at an effective solution by eliminating historical digressions and distracting facts. As a result, only useful content directly related to problem solving remains. This allows users not only to familiarize themselves with the material but also to apply it in practice to successfully solve mathematical problems.

Content selection is key not only for presenting interesting facts but also for creating scenarios that help students better absorb the material. For example, in a statistics section for middle school students, the researchers were faced with a choice between examples related to organizing a charity concert and examples focused on personal gain. As a result, they preferred the former, as it avoids distracting questions from students, such as: "What would I buy if I raised this amount?" This approach promotes a deeper understanding of the material and develops empathy in students.

Personalization Potentially Leads to Errors

The developers of the mathematics program applied the principle of personalization, which assumes that people absorb information more effectively in a conversational and relaxed style. This approach is closer to the real life of users. To address the problem of perceiving abstract concepts, the authors used cartoon characters representing children and adults. This method helps make complex ideas more accessible for visualization and understanding, which contributes to better assimilation of the material.

Fictional characters were integrated into the learning materials. For example, one of the characters in the textbook incorrectly solves a problem, which allows students to analyze his mistake. Other characters may give the same answer, suggesting different solutions, which creates an opportunity for discussion among students. Frequent use of fictitious student errors and misconceptions is intended to normalize such behavior, helping students feel more comfortable with the value of learning through their own mistakes and resolving disagreements through discussion. This approach promotes the development of critical thinking and argumentation skills in students.

However, this approach is associated with certain risks, as pointed out by instructional designers. For example, a young reader might remember an incorrect solution presented in a colorful illustration. However, a teacher, noticing gaps in a student's knowledge, can promptly make adjustments and help correct errors. It's important to remember that visual elements should support the educational process, not distract from it.

The authors were careful to ensure that errors weren't attributed solely to one character, to avoid creating unwanted stereotypes. This required care and balance in creating characters, which contributed to a deeper perception of the plot and its characters.

Reading is an important part of our lives, as it enriches our experiences and deepens our understanding of the world around us. Books, articles, and other sources of information help us develop our skills and broaden our horizons. It's important to choose quality materials that will not only help you enjoy reading but also enrich your knowledge. We recommend paying attention to current research and articles that can influence your worldview and professional activities. Reading relevant and useful texts promotes personal growth and the development of critical thinking. Adding interactivity to a course using characters can significantly increase student engagement and interest. Characters can become conduits for knowledge, helping to explain complex concepts and creating a more engaging learning experience. To effectively integrate characters into a course, start by developing unique and memorable characters that align with the course topic. These characters can have their own stories, goals, and challenges, making it easier for students to identify with them. Use characters to create scenarios and situations that students can discuss or solve. This can be useful for practicing critical thinking and problem-solving skills. Interactive elements, such as character dialogue or choice of actions, will help students actively engage in the learning process.

Also consider using multimedia materials, such as animations or videos, where characters can interact with learners. This will add visual interest and make lessons more dynamic.

Incorporating characters into a course not only makes it more interactive but also helps create an emotional connection between students and the material. This approach will help improve information retention and increase the overall effectiveness of learning.

Mayer's principles do not always help with successful content arrangement

Researchers developed illustrations with examples, diagrams, and graphs based on two of Mayer's principles. The first principle is spatial relationship, which suggests that people retain information better when captions accompanying illustrations are located directly within or near them. The second principle is signaling, which indicates that important points are highlighted and noted, which helps improve navigation. These principles contribute to improved perception and assimilation of information, making it more accessible and understandable to the audience.

British researchers took a creative approach to organizing the material, using subheadings to separate blocks of text and adding captions to illustrations. However, in practice, strict design principles sometimes created layout problems. For example, some captions did not fit within the images, and excessively close spacing between text and images caused visual clutter. As a result, it was necessary to either compress the illustrations or reduce the text size, which negatively impacted their perception. Optimizing the layout and properly distributing space between content elements are crucial for improving readability and perception of information.

Issues related to the use of colored fonts often arise when denoting mathematical structures and operations. Designers face limitations in choosing a color palette, as excessive colors in images can hinder the comprehension of information. Furthermore, individual differences in color perception can hinder content comprehension, as not everyone can distinguish all shades. Proper color selection is important for ensuring the accessibility and readability of materials. Since the materials are intended for educational use and for printing in educational institutions, the researchers decided to provide teachers with the ability to edit colors themselves. All materials are freely editable, allowing teachers to adapt them to their needs. Furthermore, with each new section, the frequency of color elements is gradually reduced, which promotes better comprehension of information and increases learning effectiveness.

Helping Beginners Potentially Harms Experienced Learners

The program developers had to grapple with an important challenge related to two key learning principles. The first principle, known as the principle of prior preparation, states that information is learned more effectively if learners are familiar with the terms and concepts used in the material. This means providing reminders of topics or including a glossary is essential for successful completion of tasks. The second principle, based on cognitive load theory, is called the principle of worked examples. It states that learners should be provided with problems that include detailed solutions and questions at the end. This approach is especially useful for those who are inexperienced, as it helps reduce cognitive load and facilitate the learning process.

Both of these principles are effective for people with limited knowledge in a given area. However, for more experienced learners, they can be not only useless but even harmful, as they present redundant information. Researchers focused on how Mayer's principles can help reduce the redundancy effect and improve learning for experienced learners. The program's creators developed several effective methods for actively engaging users. For example, in some cases, they placed compact "reminders" next to problems, highlighted in color and with corresponding subheadings. More complex examples used diagrams and color coding for clarity. Furthermore, the complexity of the examples increased gradually, and the number of examples decreased from chapter to chapter, which contributed to better learning. Examples were accompanied by illustrations and sometimes presented as dual solutions from different characters, demonstrating the existence of multiple paths to a solution. Over time, the authors increasingly focused on open questions and problem solving, refusing to offer ready-made algorithms, which contributed to the development of critical thinking in users.

The study showed that prior knowledge do not reduce, but rather increase cognitive load. This discovery sheds new light on traditional ideas about how information is absorbed. Previously, it was believed that having basic knowledge facilitates the learning process and reduces the level of load on the brain. However, new data indicate that this knowledge can complicate the perception of new information, creating additional mental effort to integrate old and new data. This study opens new horizons in understanding educational processes and can be useful for developers of educational programs and teaching methods.

What conclusion did the developers of educational materials draw?

The authors of the article will need to confirm their observations and conclusions in practice, testing them on real schoolchildren. However, they have already made an important conclusion: although the theory looks beautiful and practical, in practice it turns out to be not so convenient for application. Scientists must clarify the scope of this theory and address existing contradictions to determine its true value in the educational process.

Instructional designers cannot claim to use principles of cognitive science unless they possess the relevant knowledge. The ease of applying these principles is a myth. Research on the educational program development process emphasizes the importance of understanding the trade-offs between different principles. Such research can help instructional designers make informed, collaborative decisions when choosing approaches and finding the optimal balance between competing demands.
