The effects of a concept map-based information display in an electronic portfolio system on information processing and retention in a fifth-grade science class covering the Earth's atmosphere

An electronic portfolio system, designed to serve as a resource-based learning space, was tested in a fifth-grade science class. The control-group students accessed a traditional folder-based information display in the system and the experimental-group students accessed a concept map-based information display to review a science portfolio. The student-constructed science portfolio was a result of a collection of digital artefacts such as graphic images, instructional videos and textual files on terms and definitions relevant to the Earth's atmosphere. In the information-processing performance test, the experimental-group students scored significantly higher and spent much less time in finding answers to the questions presented. Also, in the 3-day delayed memory retention tests, the experimental-group students achieved significantly higher scores. The multiple regression models confirm that the visualisation variation is the most significant predictor for student performance (ie, comprehension and access time). Also, the regression models suggest that language-arts proficiency may reduce overall system access time; while higher math proficiency may predict retention scores.     

YouTube-based course orientation videos delivered prior to matriculation fail to alleviate medical student anxiety about anatomy

Gross anatomy is a source of anxiety for matriculating medical students due to the large volume of information presented in a truncated timeline, and because it may be their first exposure to human cadavers. This study aimed to assess if video-based resources would affect matriculating medical students' anatomy state anxiety levels. Videos were designed to be short, YouTube-based units that served to provide orientation information about the anatomy course, dissection facilities, and available study resources to dispel anxiety around beginning their anatomy studies. To evaluate the impact of the videos, students in two consecutive matriculating years (2018 and 2019) completed the validated State-Trait Anxiety Inventory and a demographic questionnaire. The 2019 cohort (n = 118) served as the experimental group with access to the videos; while the 2018 cohort (n = 120) without video access served as a historical control. Analyses revealed that the groups were equivalent in terms of trait anxiety (P = 0.854) and anatomy state anxiety even when student video exposure was controlled (P = 0.495). Anatomy state anxiety was only significantly lower in students with prior formal anatomy exposure (P = 0.006). Further inquiry into students' prior anatomy experience identified that individuals with post-secondary dissection experience were significantly less anxious than those without formal anatomical experience (P = 0.023). These results may serve as a cautionary tale to educators; while preference for video-based instructional materials is prevalent in the literature, videos delivered on public social media platforms fail to prepare students for the psychological impact of studying human anatomy.     

Exploring the effects of multimedia learning on pre-service teachers’ perceived and actual learning performance: the use of embedded summarized texts in educational media

In light of the increased usage of instructional media for teaching and learning, the design of these media as aids to convey the content for learning can be crucial for effective learning outcomes. In this vein, the literature has given attention to how concurrent on-screen text can be designed using these media to enhance learning performance. The present study sought to examine whether utilizing concurrent on-screen summarized text (CST) could improve students’ learning performance while estimating their perception of performance when learning with educational multimedia content. Although the findings did not show a significant improvement in students’ performance on the retention test among the CST groups, students exhibited a considerable higher level of confidence toward their performance. The findings suggest that students who learned with CST educational media may have overestimated their performance. Further analysis and discussion are included.     

Effects of using a second-screen application on attention,learning, and user experience in an educational content

Using a secondary device while viewing a primary device (i.e. TV), or media multitasking, is now common. Numerous researchers and practitioners have attempted to introduce secondary devices into education as a new learning environment providing additional information to the user. However, the learning-related effects of using a second screen remain controversial. This study examined the effects of second-screen-application use on attention, learning performance, and user experience per content relevance for three primary contents (PC; i.e. videos) requiring different amounts of cognitive load: low, medium, and high. Second-screen use reduced learning performance and user satisfaction when the PC required high cognitive load. However, participants exhibited increased learning performance, concentration, and satisfaction with the PC requiring medium-cognitive-load when highly relevant information was presented on the secondary screen simultaneously. Based on these findings, guidelines were suggested for designing a second-screen application without degrading users’ learning and experience.     

How the second screens change the way people interact and learn: the effects of second screen use on information processing

The use of a second screen can enhance information processing and the execution of search tasks within a given period. In this study, we examined the learner's attentional shift (AS) between two screens and controlled secondary tasks (STs) in the media multitasking setting and its effect on the learning process. In particular, we analyzed how cognitive and emotional learning effects can be explored depending on the role of this setting. A between-subject experiment was conducted with 69 participants (simultaneous vs. sequential use of a second screen in terms of open versus closed STs). The findings showed that there was a greater difference in emotional learning effects than in cognitive learning effects for participants who used a second screen. In terms of estimated emotional learning effects of media multitasking, participants engaged in sequential use demonstrated lower anxiety levels and higher competence beliefs during learning compared to participants who were engaged in simultaneous use. Moreover, an interaction effect occurred in the AS between the two screens and in controlled STs of recognition memory. These results indicate that attentional change and controlled STs are key predictors of learning effects in the media multitasking environment.     

Expertise reversal effect and sequencing of learning tasks in online English as a second language learning environment

The aim of this paper is to examine the effects of sequencing instructional materials and learners' prior knowledge on learning ESL (English as a second language) through an online learning course. 121 fifth-grade students from an elementary school in Korea participated in the study. Each participant was allocated to one cell of a 2?×?2 between-subjects factorial design, with an instructional format (i.e. sequential or concurrent) as a first factor, and prior knowledge (i.e. high or low) as a second factor. Instructions of the words and grammar rules were allocated to each page for the sequential group, whereas integrated on a single page for the concurrent group. The result indicates that the sequential instruction of words followed by grammar explanations was more effective for the students with higher levels of prior knowledge than the concurrent presentation. The reverse was also found for the students with lower levels of prior knowledge in English. There are four possible explanations for the results. First, split-attention effect, temporal-contiguity effect, or transient information effect might occur. Second, worked-example effect might occur and over-ride the effect of sequencing. Third, intrinsic and extraneous cognitive load might intertwine each other. Last, the levels of element interactivity in two instructional formats might be different from each other. The implications for instructional designers and future research are discussed.     

Mind wandering,control failures,and social media distractions in online learning

Mind wandering often leads to performance and accuracy errors during activities that are demanding and require concentration. Students are often asked to concentrate on demanding tasks in their studies, and by the nature of this principle, off-task thinking would inherently be prohibitive to their success. Further, the distracting nature of social media and technology may greatly increase the likelihood of mind wandering when students are engaged in online learning, requiring them to engage with said technology. To examine the relationships among working memory, interest, mind wandering and performance, 126 participants from at a large Midwestern state university completed three complex span tasks, responded to mind-wandering probes while watching two online lectures and rated interest in the lecture topics. Higher levels of mind wandering predicted lower levels of academic performance. Lower levels of working memory capacity predicted higher levels of mind wandering and lower levels of academic performance. Higher levels of topic interest predicted lower levels of mind wandering. A novel mind wandering probe, thinking about or using another technology, accounted for 29% of all off-task thinking.     

Daily interest,engagement, and autonomy support in the high school science classroom

The current investigation examined relations between high school students’ daily and cumulative situational interest in science class and their engagement, as well as their perceptions of the motivational climate of the classroom. Two-hundred and eighteen high school students in 43 science classes participated in a diary study in which students provided reports of their classroom experiences after each class session for a six-week instructional unit. Multilevel modeling results suggested that interest during science class and behavioral engagement declined over the course of the unit. Daily and cumulative interest during science class predicted behavioral engagement (working hard, participating, and paying attention), cognitive engagement, and agentic engagement. Students’ interest during science class also predicted perceptions that teachers engaged in the motivationally supportive practice of emphasizing student choice during the same and the following class day. Results suggested that the links between interest with working hard and perceptions of choice provision were stronger early in the instructional unit compared to later in the unit. Moreover, some variation was found in these relations depending on students’ gender and ethnicity, as well as depending on the course content and level. Implications for practice, theory, and future research are discussed.     

How do students’ achievement goals relate to learning from well-designed instructional videos and subsequent exam performance?

Well-designed instructional videos are powerful tools for helping students learn and prompting students to use generative strategies while learning from videos further bolsters their effectiveness. However, little is known about how individual differences in motivational factors, such as achievement goals, relate to how students learn within multimedia environments that include instructional videos and generative strategies. Therefore, in this study, we explored how achievement goals predicted undergraduate students’ behaviors when learning with instructional videos that required students to answer practice questions between videos, as well as how those activities predicted subsequent unit exam performance one week later. Additionally, we tested the best measurement models for modeling achievement goals between traditional confirmatory factor analysis and bifactor confirmatory factor analysis. The bifactor model fit our data best and was used for all subsequent analyses. Results indicated that stronger mastery goal endorsement predicted performance on the practice questions in the multimedia learning environment, which in turn positively predicted unit exam performance. In addition, students’ time spent watching videos positively predicted practice question performance. Taken together, this research emphasizes the availing role of adaptive motivations, like mastery goals, in learning from instructional videos that prompt the use of generative learning strategies.     

The influence of prior knowledge and viewing repertoire on learning from video

Video is increasingly used as an instructional tool. It is therefore becoming more important to improve learning of students from video. We investigated whether student learning effects are influenced through an instruction about other viewing behaviours, and whether these learning effects depend on their prior knowledge. In a controlled environment, 115 students watched a number of instructional videos about the technical equipment needed in a course on digital photography. Every second student was instructed about other possible viewing behaviours. A pre-post-retention test was carried out to calculate learning effects. The differences with respect to the learning effects of students who received an awareness instruction on an alternative viewing strategy were not significantly different. The differences as observed in our earlier experiment however could not be reproduced. Students with a broad viewing repertoire showed higher learning effects than students with a narrow repertoire. Furthermore, students with a strategic viewing approach also showed higher learning effects. Certain conditions have to be met: the technical and didactical quality of the video must be good, the integration in a learning task must be apparent, students must be aware of their viewing behaviour, and teachers must be aware of their students’ viewing behaviour in order to enrich the viewing repertoire of students when they have at least some basic knowledge e.g. after several lessons on the topics at hand. In future research, this study should be replicated using more complex video episodes than the instruction videos we used in our experiments that were only on the factual knowledge level of the taxonomy of Bloom. Moreover, replication of this study with a larger sample size could yield a significant improvement in learning effects. This is plausible because students need an amount of prior knowledge beyond a certain threshold value in order to be able to expand their knowledge network in their long term memory. Finally, additional media player functionality, facilitating effective student learning from video, can be described based on the results of this study.     

Wounded Healers: Graduate Students with Histories of Trauma in a Family Violence Course

Social work students are witness to a variety of challenges from course content through scenarios, videos, role-plays, and field practice. Students may be vulnerable to experiencing vicarious traumatization from this exposure. Some students, however, may have personal histories of trauma and may therefore experience posttraumatic stress reactions due to triggering of past trauma through course content. This case study examines feedback from three graduate students from a family violence class who self-identified that they had personal histories of trauma from family violence. Their feedback can be beneficial to instructors in managing students' reactions that might be triggered from course content.     

Looks Like Me,Sounds Like Me! Race,Culture, and Language in the Creation of Digital Media

The technology education movement includes the introduction and application of digital books into science classrooms. These digital books are attractive alternatives to traditional texts because they can be customized for students. This qualitative study examined 35 students as they customized their own digital books. Using a variety of digital photos and videos, each student was asked to drag and drop images into their text. The students were provided with a variety of digital photos and videos to use to customize their books. The images were identical except for the racial cues of the characters. We used content analysis of students' selections and interviews of students (N = 35). We discovered that cues about racial authenticity served as the primary motivation for students selecting particular images. As students were given options, they consistently chose images that reflected their racial, gender, and linguistic identities. The results of this study indicate the need to recognize how racial cues can help students draw deeper connections to digital media if those cues are culturally authentic. This implies that culturally authentic racial cues would spawn deeper engagement for students.     

Cognitive style and instructional preferences

The aim of the study was to investigate the relationship between learners' cognitive styles and their instructional preferences. The sample consisted of 240 business studies students at a UK university. Subjects' cognitive styles were assessed using the Cognitive Styles Analysis (which assesses the wholist-analytical and verbaliser-imager dimensions of style) and their instructional preferences assessed using an instructional preferences inventory which consisted of three sub-inventories (instructional method, instructional media and assessment method). Overall subjects favoured dependent methods, print based media and informal assessment methods. There was a significant main effect of wholist-analytical style on collaborative method preference (role play, group discussions and business games) and non-print based media preference (overhead transparencies, slides and videos). There was an interaction of the two dimensions of style and gender in their effect on informal assessment method preferences (individual and group assignments and multiple choice and short answer-type questions). The findings are discussed in terms of: (i) models of the cognitive style construct; (ii) the practical implications of individual differences in style and preference.

The Impact of Video Length on Learning in a Middle-Level Flipped Science Setting: Implications for Diversity Inclusion

Popularity of videos for classroom instruction has increased over the years due to affordability and user-friendliness of today’s digital video cameras. This prevalence has led to an increase in flipped, K-12 classrooms countrywide. However, quantitative data establishing the appropriate video length to foster authentic learning is limited, particularly in middle-level classrooms. We focus on this aspect of video technology in two flipped science classrooms at the middle school level to determine the optimal video length to enable learning, increase retention and support student motivation. Our results indicate that while assessments directly following short videos were slightly higher, these findings were not significantly different from scores following longer videos. While short-term retention of material did not seem to be influenced by video length, longer-term retention for males and students with learning disabilities was higher following short videos compared to long as assessed on summative assessments. Students self-report that they were more engaged, had enhanced focus, and had a perceived higher retention of content following shorter videos. This study has important implications for student learning, application of content, and the development of critical thinking skills. This is particularly paramount in an era where content knowledge is just a search engine away.     

Potential Values of Incorporating a Multiple‐Choice Question Construction in Physics Experimentation Instruction

The potential value of a multiple‐choice question‐construction instructional strategy for the support of students’ learning of physics experiments was examined in the study. Forty‐two university freshmen participated in the study for a whole semester. A constant comparison method adopted to categorize students’ qualitative data indicated that the influences of multiple‐choice question construction were evident in several significant ways (promoting constructive and productive studying habits; reflecting and previewing course‐related materials; increasing in‐group communication and interaction; breaking passive learning style and habits, etc.), which, worked together, not only enhanced students’ comprehension and retention of the obtained knowledge, but also helped distil a sense of empowerment and learning community within the participants. Analysis with one‐group t‐tests, using 3 as the expected mean, on quantitative data further found that students’ satisfaction toward past learning experience, and perceptions toward this strategy’s potentials for promoting learning were statistically significant at the 0.0005 level, while learning anxiety was not statistically significant. Suggestions for incorporating question‐generation activities within classroom and topics for future studies were rendered.
