Why do learners of different ages experience cognitive load so differently?
In today's diversified learning environment, cognitive load theory has gradually gained attention, especially among learners of different age groups. The theory was developed by John Sweller in the late 1980s to help improve the effectiveness of instructional design and to emphasize the impact of working memory limitations on learning. This means that the burden learners face when processing information may directly affect their learning outcomes, and this burden varies significantly among different age groups.
Cognitive load can be divided into three categories: intrinsic cognitive load, extraneous cognitive load, and value-added cognitive load. Intrinsic cognitive load is usually related to the difficulty of the learning material itself; extrinsic cognitive load is caused by the way the information is presented; and value-added cognitive load involves how learners effectively manage their cognitive resources to promote long-term memory. Establish.
Learners of different age groups may experience vastly different cognitive loads when faced with the same learning task.
The impact of age
Studies have shown that age significantly affects the experience of cognitive load. For example, older adults may experience higher cognitive load when performing the same cognitive task due to decreased memory and information processing speed. According to a study, as people age, their working memory capacity tends to decrease, which negatively affects their problem-solving abilities.
Increased cognitive load in older adults is often associated with declines in balance and cognitive function.
Students and children also face different cognitive loads relative to this group. Students often face excessive external cognitive load when using electronic products such as laptops and social media, which directly affects their academic performance.
Student Challenges
Today's students are often multi-tasking, such as using their laptops during class while browsing social media. This behavior not only increases cognitive load but also reduces their learning efficiency. Studies have shown that increased cognitive load can cause students to lose focus, which in turn affects their GPA and academic performance.
Especially those students who frequently use Facebook often interact with the students next to them, resulting in poor learning outcomes.
Children’s cognitive load
For children, cognitive load changes as they age. Young children usually lack foundational knowledge and world experience, which makes them face a higher cognitive load during the learning process. Research shows that children who live in poverty often experience higher cognitive loads due to a lack of exposure to school-related topics, vocabulary, and concepts.
The use of gestures has become an effective strategy for children to reduce cognitive load when communicating and help them express their ideas.
The impact of different socioeconomic conditions
In addition, socioeconomic status is also a key factor affecting cognitive load. People experiencing poverty often face stressors from their life circumstances that further increase their cognitive load. According to the study, school-age children from low-income families experience significantly higher predicted cognitive load in learning environments than middle-class children.
Challenges Ahead
With the advancement of technology and the diversification of learning environments, we must pay more attention to the differences in cognitive load among learners of different ages. This can not only help educators optimize teaching design, but also promote the improvement of learning efficiency. In today's society filled with electronic products and social media, how to effectively manage cognitive load will become a topic of great concern.
So, in the face of increasing cognitive load, how should we design more effective learning environments to support learners of different ages?
