Cognitive load theory and multimedia learning, task characteristics, and learning engagement: The current state of the art

Kirschner, F., Kester, L., & Corbalan, G. (2011). Cognitive load theory and multimedia learning, task characteristics, and learner engagement: The current state of the art. Computers in Human Behavior, 27, 1-4. doi:10.1016/j.chb.2010.05.003This special issue consists of 16 empirical papers, as well as a discussion based on the Third International Cognitive Load Theory Conference held at the Open Universiteit (Heerlen, The Netherlands) in 2009. All papers focus on improving instructional design from a cognitive load theory (CLT: Sweller, 1988; Sweller, Van Merriënboer, & Paas, 1998; Van Merriënboer & Sweller, 2005) perspective. They cover a wide variety of topics in which learner characteristics, tasks characteristics, and the interaction between both are studied in, new, innovative, but also traditional ways, thereby providing an overview of the current state of the art on CLT research. The overarching goal of all studies is to gain more understanding and insight into the optimal conditions under which learning can be successful, and students will be able to apply their acquired knowledge and skills in new or familiar problem solving situations. Together, the papers comprise three ways in which this overarching goal is reached: (1) by studying multimedia learning environments, (2) by studying different characteristics of a learning task and, (3) by studying how learners can be actively engaged in the learning process. Although, the research focus of most papers fit nicely within these research topics, some overlap is inevitable. The categorization has been made on the basis of the most prominent research focus and findings of each study

Contemporary cognitive load theory research: The good, the bad and the ugly

Kirschner, P. A., Ayres, P., & Chandler, P. (2011). Contemporary cognitive load theory research: The good, the bad and the ugly. Computers in Human Behavior, 27(1), 99-105. doi:10.1016/j.chb.2010.06.025This paper reviews the 16 contributions of the special issue entitled Current Research in Cognitive Load Theory. Each paper is briefly summarized and some critical comments made. The overall collection is then discussed in terms of the positive contributions they make to the field of learning and instruction, and cognitive load theory in particular (the good), as well as problematical issues such as unresolved explanations and conflicting results (the bad) and the special case of measuring cognitive load (the ugly)

Tracking eye movements when solving geometry problems with handwriting devices

The present study investigated the following issues: (1) whether differences are evident in the eye movement measures of successful and unsuccessful problem-solvers; (2) what is the relationship between perceived difficulty and eye movement measures; and (3) whether eye movements in various AOIs differ when solving problems. Sixty-three 11th grade students solved five geometry problems about the properties of similar triangles. A digital drawing tablet and sensitive pressure pen were used to record the responses. The results indicated that unsuccessful solvers tended to have more fixation counts, run counts, and longer dwell time on the problem area, whereas successful solvers focused more on the calculation area. In addition, fixation counts, dwell time, and run counts in the diagram area were positively correlated with the perceived difficulty, suggesting that understanding similar triangles may require translation or mental rotation. We argue that three eye movement measures (i.e., fixation counts, dwell time, and run counts) are appropriate for use in examining problem solving given that they differentiate successful from unsuccessful solvers and correlate with perceived difficulty. Furthermore, the eye-tracking technique provides objective measures of students’ cognitive load for instructional designers

Effects of Task Experience and Layout on Learning from Text and Pictures with or without Unnecessary Picture Descriptions

The presentation of extraneous (i.e., irrelevant or unnecessary) information may hamper learning with multimedia. The present study examined whether people can learn to ignore unnecessary information with increasing experience with the task and whether this depends on the layout of that information. In two experiments, participants learned about the process of mitosis from a multimedia slideshow, with each slide presenting a combination of expository text and a picture on one of the stages in the process. Slides either contained no unnecessary text (control condition) or unnecessary text (i.e., merely describing the picture) either integrated in the picture (integrated condition) or presented underneath the picture (separated condition). Knowledge about the studied mitosis phase was tested immediately after each slide using a cloze test. Across Experiments 1 and 2, we did not find a reliable negative effect of the unnecessary text on cloze test performance. As a result, the question of whether task experience would reduce or eliminate that negative effect could not be answered. The eye movement data did confirm, however, that participants attended less to the unnecessary information with increasing task experience, suggesting that students can adapt their study strategy and learn to ignore unnecessary information

Kesan interaksi atribut persembahan multimedia, gaya kognitif, peringkat pengajian dan bidang pengajian ke atas daya ingatan visual pelajar IPT

Various multimedia presentation attributes contribute different positive effect on the visual recall memory due to factors such as different cognitive style, field of study and level of study. The positive effects could not be optimised if the most effective combination of the factors is not identified. This study aimed to identify the main effects and interaction effects of multimedia presentation format or attribute (line drawing pictures, black and white pictures, colour pictures, animation, animationaudio), cognitive styles (field dependence (FD), field independence (FI), level of study (year one, year three) and field of study (art-based, non-art-based) on the visual recall among students in higher education institutions (HEIs) in Malaysia. The sample consisted of 400 year one and three university students. This experimental study used 5 x 2 x 2 x 2 factorial design. The findings showed that the main effects of format of multimedia presentation, cognitive style, level of education and field of study on visual recall were significant. The results showed that students who viewed animated presentation obtained better mean scores on visual recall than students who viewed other presentation formats. Students with FI cognitive styles were found to recall better than the FD students, while students from non-art-based field obtained better scores than students from the art-based field. Year one students were found to have better visual recall than year three students. The interaction effect of format of multimedia presentation and level of education on visual recall was significant. The three-way interaction effect between cognitive styles, level of education and field of study as well as the interaction effect between format of multimedia presentation, level of education and field of study on visual recall were significant. Findings of the study support the effectiveness of multimedia presentation in enhancing the visual recall memory. However, the most effective attribute should be aligned with the students’ cognitive style, field of study and level of study so as to achieve the intended learning outcomes

Augmentation of information in educational objects: Effectiveness of arrows and pictures as information for actions in instructional objects

The use of information and communication technology (ICT) in education is now central to facilitating links between learners, resources and instructors. Regardless of whether it is used in distance education or educational objects, ICT enables educators to package education opportunities in an increasing number of alternative ways so as best to meet the varying needs of the end user. Currently, one of the challenges that face instructors is to develop materials that enhance the learner-content interaction by reducing extraneous cognitive load while at the same time facilitating learning. This study explored the effectiveness of pictorial information and augmentation in instructions and educational objects. Dual coding theory is used to suggest that information that can be processed via separate but interconnected systems will facilitate faster processing and deeper learning of the information. University students were randomly assigned to six experimental conditions to perform a novel task using six different instruction manuals. A 3 (text, text-pictorial, text-pictorial-arrows) X 2 (picture of object vs. no picture of object) design was used to test whether augmenting text with pictorial information provided additional valuable information in instructional settings. Results partially support this multimedia effect; participants exhibited superior performance in a Text-Pictorial and Text-Pictorial-Arrows format over Text format. A picture of the object also facilitated superior performance on both the assembly and operating tasks, especially in a text format. Overall, combinations of text-pictorial and text-pictorial-arrows facilitated faster assembly and operation; they reduced errors, extra procedures, and unsuccessful assemblies (uncorrected errors). Results also support the idea that arrows convey unique types of information and function. In particular, arrows may attune people to important information and/or convey information movement that guides actions during tasks. Practical implications are discussed in relation to the type of information combinations that may lead to superior instructional design of instructional objects and research, including how to reduce errors of omission

Learning with self-generated drawings and the impact of learners’ emotional states

IntroductionThe present study examined the influence of emotional states when learning with self-generated drawings. It was assumed that learners in a positive emotional state would profit from learning with self-generated drawings, while learners in a negative emotional state would not profit from this strategy to the same extent but would rather benefit through reading.MethodsUniversity students (N  =  123) were randomly assigned to one of four conditions resulting from a 2  ×  2 design with self-generated drawings (yes vs. no) and emotional state (positive vs. negative) as independent variables.ResultsResults showed that learning with self-generated drawings was more beneficial for a following transfer test than learning without drawings – irrespective of a learner’s emotional state. The quality of self-generated drawings predicted the learning outcomes of the retention and pictorial test, but not for transfer.DiscussionMissing effects of emotional states and the missing interaction with self-generated drawings will be discussed

Master of Science

thesisThe current study utilized a meta-analysis review to investigate the sensitivity of several cognitive load measures. Specifically, the study examined whether self-rating, single-task performance, dual-task performance, eye-track, or physiological measures are most sensitive to changes in cognitive load. Additionally, the sensitivity of load measures was analyzed in relation to several variables such as age, research design, and learning content. After the initial search, 224 publications were identified and coded for inclusion in the meta-analysis. A random-effects model was employed, and the results demonstrated that cognitive load sensitivity varied by measure type. The load sensitivity among the study characteristics of age, content area, and research design also varied corresponding to specific cognitive load measure types. The number of self-rating items used to assess cognitive load did not significantly vary between single item and multiple item scales. Lastly, cognitive load sensitivity did not vary significantly among the measures in relation to peak and overall load. The last result may be biased by a small sample size of peak measures (n = 8)
