"Do screen captures in manuals make a difference?": a comparison between textual and visual manuals

Examines the use of screen captures in manuals. Three types of manuals were compared: one textual and two visual. The two visual manuals differed in the type of screen capture that was used. One had screen captures that showed only the relevant part of the screen, whereas the other consisted of captures of the full screen. All manuals contained exactly the same textual information. We examined immediate use on time (use as a job aid) and on learning (use as a teacher). For job-aid purposes, there was no difference between the manuals. The visual manual with full-screen captures and the textual manual were both better for learning than the visual manual with partial screen captures. We found no effect on user motivation. The tentative conclusion of this study is that screen captures seem not to be vital for learning or immediate use. If one opts for including screen captures, then the conclusion is that full-screen captures are better than partial one

Exploration of concise redundancy in online multimedia learning

With the rapid growth of multimedia in education, the importance of investigating the effect of redundancy, repeating instructional messages to enhance conceptualization in instructional material design, is becoming more important. Various studies have been conducted recently regarding the effects of different forms of redundancy. A multimedia lesson presenting concurrent on-screen text, still graphics or animations, and narration is a typical setting in redundancy research. Concise redundancy is the revision of the on-screen text into a concise form which is presented to the learners concurrently with visualizations and narration. The purpose of this study was to investigate, while controlling for spatial ability, the effects of concise redundancy on students\u27 retention and confidence when learning with highly complex multimedia materials. In addition, the effects of animation or still graphics along with text redundancy were examined. No significant differences were found between the graphic presentations (animation or series of stills) and text redundancy groups (full, concise, or none) on retention or levels of confidence. When examining the results taking into account high and low spatial abilities, no significant differences were found in terms of different graphic presentation (animation or series of stills) and different text redundancy groups (full, concise, or none). However, in one condition, low spatial ability learners exhibited significantly higher levels of confidence than high spatial ability learners when learning with narrated static graphics and concise redundancy. The current study should provide further guidance for researchers who are interested in examining narrated multimedia lessons containing concise redundancy when comparing static graphics to animated graphics

Verbal redundancy in a procedural animation: On-screen labels improve retention but not behavioral performance

Multimedia learning research has shown that presenting the same words as spoken text and as written text to accompany graphical information hinders learning (i.e., redundancy effect). However, recent work showed that a “condensed” form of written text (i.e., on-screen labels) that overlaps with the spoken text, and thus is only partially redundant, can actually foster learning. This study extends this line of research by focusing on the usefulness of on-screen labels in an animation explaining a procedural task (i.e., first-aid procedure). The experiment had a 2 × 2 × 2 between-subject design (N = 129) with the factors spoken text (yes vs. no), written text (yes vs. no), and on-screen labels (yes vs. no). Learning outcomes were measured as retention accuracy and behavioral performance accuracy. Results showed that on-screen labels improved retention accuracy (but not behavioral performance accuracy) of the procedure, especially when presented together with spoken text. So, on-screen labels appear to be promising for learning from procedural animations

A Comparison of Three Levels of Verbal Redundancy in Multimedia Learning and Its Effects on Memory Retention and Transfer in Legal Professionals

This study sought to examine verbal redundancy in multimedia learning and its effects on memory retention and transfer in legal professionals who were randomly assigned to watch one of three multimedia videos. Tests of ANOVA showed no significant differences in performance, mental load, or combined efficiency scores among the three instructional groups, but participants in the complementary text group rated the video with complementary slides as significantly more helpful than the videos with redundant, overloaded text slides and spoken words only. Factorial ANOVA also revealed that the redundant text group with fewer than five years of experience scored significantly lower than other groups. The cognitive load of the learners was discussed and recommendations included assessing the prior knowledge of learners, reducing extraneous and redundant text, and including relevant graphics with words

Reimagining the Chalk Talk: Animated Handwriting as a Social Cue to Improve Motivation in Multimedia Video Lessons

Animated handwriting in multimedia video lessons, such as those popularized by the Khan Academy, has reimagined the classic teaching technique of writing on a chalkboard while lecturing for online delivery. This digital chalk talk effect mimics classroom lectures where words are written letter by letter on a chalkboard as they are spoken. Low-cost applications, tablets, and document cameras allow instructors at all levels to easily create their own animated handwritten videos. As adoption increases, it is important to understand the effects of this strategy. This study employed a true experimental, between-subjects, posttest design that compared multimedia lessons with different text display formats on outcomes of motivation, mental effort, and learning. Undergraduate student volunteers (n = 234) from a large U.S., West Coast, regional, four-year public university were randomly assigned to one of three treatments: Animated handwritten, animated typewritten, or static typewritten. Each group watched a different version of a five-segment, twelve-minute multimedia lesson about cryptography. Lessons differed only in the visual text display format and contained identical narration and content. Results indicated that multimedia with animated handwritten text produced strong social cues motivating learners. Participants who viewed the animated handwriting reported significantly greater social agency attitudes toward the learning experience than with static typewritten text. They perceived the narrator’s voice as more dynamic with animated handwriting when compared to static, even though the voice was identical. They also reported more attention to the lesson and materials with animated handwriting than either animated typewritten or static typewritten. These motivational gains are accomplished without introducing extraneous cognitive load or negatively impacting learning outcomes. Significant findings from this research demonstrated that animated handwritten text is more than just a signaling strategy. The combination of text being hand-drawn and appearing as if a real person is writing it in real time adds a powerful social cue. Results of this study demonstrate that using animated handwriting in multimedia video lessons is an effective way to increase motivation through social cues that can be accomplished without requiring expansive technical knowledge, expensive equipment or extensive time investments
