A closer look at split visual attention in system- and self-paced instruction in multimedia learning

Two experiments examined visual attention distribution in learning from text and pictures. Participants watched a 16-step multimedia instruction on the formation of lightning. In Experiment 1 (N = 90) the instruction was system-paced (fast, medium, slow pace), while it was self-paced in Experiment 2 (N = 31). In both experiments the text modality was varied (written, spoken). During learning, the participants’ eye movements were recorded. Results from both experiments revealed that learners spent more time studying the visualizations with spoken text than those with written text. In written text conditions learners consistently started reading before alternating between text and visualization; moreover, they spent more time reading the text than inspecting the visualizations. While in Experiment 1 additional time that was made available in conditions with a slow or medium instruction pace was spent inspecting visualizations, in Experiment 2 longer learning times resulted from reading the text more intensively. With respect to learning outcomes (retention, transfer, and visual memory) Experiment 1 revealed an effect of text modality for visual memory only. In Experiment 2 no modality effects were found. Instruction pace was hardly related to learning outcomes. Overall, the results confirm prior findings suggesting that the distribution of visual attention in multimedia learning is largely guided by the text.     

Role of morphological awareness in biliteracy development: Within- and cross-language perspectives among Korean ESL learners in grades five and six

The study investigated the within- and cross-language contribution of morphological awareness (MA) to vocabulary and reading comprehension among students learning to read two typologically different orthographies at the same time: Korean and English. Fifty Korean ESL learners in grades five and six were administered Korean and English measures of MA (derivational and compound morphemes), vocabulary, and reading comprehension (narrative and expository texts), in addition to measures of phonological awareness (PA) and orthographic awareness (OA). Information about home language environment was also obtained from a parental questionnaire. Path analysis showed that MA was the most significant contributor to vocabulary (β = 0.33, p < 0.05) and reading comprehension (β = 0.46, p < 0.01) in English; and in Korean (β = 0.62 and β = 0.54, respectively, all ps < 0.01), controlling for effects of PA and OA. Unidirectional cross-language transfer was found from Korean MA to English vocabulary (β = 0.27, p < 0.05) and reading comprehension (β = 0.22, p < 0.05) and multiple determining factors are discussed. Educational implications and research recommendations are also presented.     

Dynamic task selection: Effects of feedback and learner control on efficiency and motivation

Structural features of learning tasks are relevant for problem solving but not salient for novice learners. Feedback in the form of Knowledge of Correct Response (KCR) during practice is expected to help learners recognize the structural features and to profit from learner control over the selection of learning tasks. A 2 × 2 factorial experiment (N = 118) was conducted to study the effects of the KCR feedback (present and absent) and control over the selection of learning tasks (learner control and program control). The presence of the KCR feedback yielded higher efficiency on a near-transfer test as well as higher learner motivation. An interaction between feedback and control, indicating extra beneficial effects of feedback when learners control the selection of learning tasks, was not found. Theoretical and practical implications are discussed.     

How do we learn in a negative mood? Effects of a negative mood on transfer and learning

Findings show that both positive and negative mood may hinder or promote information processing. In two experiments, we show that negative mood impairs transfer effects and learning. In the first experiment, N = 54 participants drawn from a training course for the Swiss Corps of Fortification Guards first learned to solve the three- and four-disk Tower of Hanoi (ToH) problem to mastery level. After mood induction, they were asked to solve one proximal (five-disk ToH) and two distal transfer tasks (the Missionary and Cannibal Problem and the Katona Card Problem). Participants in a negative mood solved the transfer tasks less efficiently. In the second experiment, this result was replicated with a sample of N = 80 participants drawn from a training course for nurses. Additionally, mood affected performance if it was induced before the learning phase; participants in a negative mood needed more repetitions to reach the mastery level and also performed worse in the transfer tasks, although there were no greater mood differences in this problem-solving phase. The implications for the design of learning settings are discussed.     

Comprehending animations: Effects of spatial cueing versus temporal scaling

In the present experiment the animation of the operating mechanism of a pendulum clock was used in order to compare the effects of spatial cueing with those of temporal scaling on the comprehension of the animation. The presentation speed of the clock mechanism (normal vs. fast) and signalling cues to three different parts of the mechanism (weight, pendulum, and an irrelevant gear as blinking elements) were used in a 2 × 3 between subjects design with 144 participants. It was found that compared to normal speed condition, understanding was improved in the fast speed condition, but was unaffected by any of the cueing conditions. The results indicate that, although guidance of attention to relevant parts of an animation is often seen as a key to effective instructional design, the way temporal manipulations affect understanding is independent from local attention guiding.     

Does IQ matter in adolescents' reading disability?

We studied the connection of IQ, reading disability (RD) and their interaction with reading, spelling and other cognitive skills in adolescents with average IQ and RD (n = 22), average IQ, non-RD (n = 71), below average IQ and RD (n = 29), and below average IQ non-RD (n = 33). IQ was not connected to reading and spelling in subjects without RD, but a connection to non-word spelling in subjects with RD existed. IQ and RD showed a connection to other cognitive skills (IQ to working memory, verbal memory and syntactic skills, RD to poor performance in text reading and rapid naming and both of them to reading comprehension, phonological and arithmetic skills), but no interaction existed. Our results are consistent with those of earlier studies showing that IQ does not play a significant role in the presentation of RD. However, adolescents with below average IQ and RD seemed to have much broader deficits in academically important skills such as arithmetic and reading comprehension than the other groups.     

Children's acquisition of science terms: Simple exposure is insufficient

The ability of school children (N = 233) to acquire new scientific vocabulary was examined. Children from two age groups (M = 4.8 and M = 6.5) were introduced to previously unknown words in an educational video. Word knowledge was assessed through accuracy and latency for production and comprehension over a 9-month period. A draw and write task assessed acquisition of domain knowledge. Word learning was poorer than has previously been reported in the literature, and subject to influences of word type (domain specificity) and word class. The results indicate that the acquisition of scientific terms is a complex process moderated by lexical, semantic and pragmatic factors.     

The influence of visual cognitive style when learning from instructional animations and static pictures

In a 2 × 2 design, we examined the role of visual cognitive style in two multimedia-based learning environments (text plus static pictures/animations). A statistically significant interaction was obtained for deeper comprehension: Highly developed visualizers (HDV) who learned with static pictures performed better than HDV who learned with animations, and less developed visualizers (LDV) performed the same with static pictures or animations.For factual knowledge, there was a main effect in favor of HDV. Subsequent tests revealed that HDV outperformed LDV only when learning from static pictures, but not when studying animations. There were no overall differences between animations and static pictures. The assumption is made that HDV benefit from their cognitive style when they have to construct a mental animation from static pictures.Concluding, we did not find any rationale for converting static pictures to animations — HDV learned better with static pictures, while for LDV, it made no difference.     

Achievement and engagement: How student characteristics influence teacher judgments

Teachers' judgments of student characteristics are affected not only by the characteristic in question, but also by other factors. This article presents three studies examining whether students' achievement influences teachers' judgments of their engagement (as a proxy for motivation) and vice versa. First, a field study was conducted with N = 52 teachers and N = 1135 students. Structural equation modeling revealed an effect of student achievement on teacher judgments of student engagement and an effect of student engagement on teacher judgments of student achievement—above and beyond the association of each student characteristic with teacher judgments of that characteristic. These results were then replicated in two experimental studies involving a computer simulation of an instructional situation, the Simulated Classroom, with N = 40 and N = 181 teacher candidates, respectively. The psychological determinants of the effects observed are discussed, as are their practical implications.     

Making the right connections: Differential effects of reading intervention for subgroups of comprehenders

The purpose of this study was to compare the effects of different types of questioning interventions on students' reading comprehension. Fourth-grade students (n = 246) were identified as struggling, average, or good readers and assigned randomly within school to one of three questioning interventions: two inferential conditions (Causal or General) or one literal condition (“Who, What, Where, When” or W-questioning). Teachers delivered the interventions for 20–30 min, 2–4 times per week, for 8–10 weeks. All readers made reliable pre- to posttest comprehension gains as measured by story recall (ps < .001 to .04). Differential effects for intervention were found between two subgroups of struggling comprehenders—elaborators and paraphrasers. Elaborators benefited more than paraphrasers from Causal questioning (d = .86) whereas paraphrasers benefited more than elaborators from General questioning (d = 1.46). These findings suggest that identifying subgroups is important in developing and evaluating the effectiveness of reading comprehension interventions.     

The onion model: Myth or reality in the field of individual differences psychology?

To bring order in concepts related to individual learner differences, Curry (1983) designed the three-layered onion model. As this model provides an interesting way to distinguish related concepts – such as cognitive styles and approaches to studying – on the basis of their stability in learning situations, ample studies build further on this model. Given that only few studies have been conducted to empirically test the model, we conducted two studies to address this research gap. In the first study (N = 113), analyses do not show a clear causal path from three concepts belonging to different layers in relation to learning outcomes. In the second, longitudinal study (N = 162), no support is found for differences in stability between cognitive styles and approaches to studying. Our research does not provide solid evidence for the onion model, which warns to be cautious with applying the assumptions of theoretical models in educational practice without empirical support.     

Reciprocal effects between fluid and crystallized intelligence and their dependence on parents' socioeconomic status and education

The investment theory of Cattell supposes an influence of fluid on crystallized intelligence. The development of fluid intelligence largely depends on biological factors, of crystallized intelligence on fluid intelligence and environmental stimulation. To test this theory two contrasting samples representing a broad ability range were chosen, a Brazilian sample (ages 7 to 15, N = 833, mean IQ 92) and a sample with a higher ability level in Germany (ages 11 to 19, N = 722, IQ 118). Analyses of cross-lagged effects across two year intervals show similar effects of fluid intelligence on crystallized and vice versa (around β = .17). Parental socioeconomic status and parental education have in both samples a slightly stronger effect on crystallized than on fluid intelligence. The first result refutes Cattell's theory, the second gives some support. The development of fluid intelligence also seems to be influenced by non-biological environmental factors resulting in a concept of intelligence as a malleable ability.     

Prerequisite knowledge and time of testing in learning with animations and static pictures: Evidence for the expertise reversal effect

An animation can have an informational advantage over a static picture by depicting dynamic features. The aim of this study was to investigate whether the provision of prerequisite knowledge can help learners infer dynamic features from a static picture. It was assumed that this supposedly more active processing with a static picture would result in longer lasting knowledge representations. A 2 × 2 × 2 between-subjects design with visualization format (static picture vs. animation), prerequisite knowledge (provided vs. not provided), and time of testing (immediate vs. one week later) was used (N = 260). The results of a transfer test showed that learners with low prerequisite knowledge benefited from the animation, but this was not the case for learners with high prerequisite knowledge. Time of testing had no influence. In line with the expertise reversal effect, prerequisite knowledge not only fostered learning with the static picture but also hindered learning with the animation.     

Effects of instruction on changes in epistemological beliefs

In this study, we investigated the effects of teaching critical-thinking principles on university students’ epistemological beliefs, whether these effects had any relation to the teaching approaches, and whether there was any significant interaction effect between teaching approach and students’ epistemological beliefs. One hundred and eight undergraduates were randomly assigned to three different 65-min instructional interventions, namely, General, Infusion, and Immersion approaches. Statistical analyses of the data using a Repeated Measures ANOVA showed a statistically significant higher post-assessment performance, F (1, 105) = 19.769, p = .00. The main effect related to the intervention was also significant, F (2, 105) = 3.995, p = .021, but there was no significant interaction between intervention and epistemological beliefs. Post hoc comparisons revealed that students assigned to the Infusion strategy outperformed those assigned to the General approach on epistemological change.     

Do learning protocols support learning strategies and outcomes? The role of cognitive and metacognitive prompts

Although writing learning protocols is an effective follow-up course work activity, many learners tend to do it in a rather suboptimal way. Hence, we analyzed the effects of instructional support in the form of prompts. The effects of different types of prompts were investigated in an experiment with four conditions: cognitive prompts, metacognitive prompts, a combination of cognitive and metacognitive prompts, or no prompts (N = 84 undergraduate psychology students). We found that the prompts stimulated the elicitation of cognitive and metacognitive learning strategies. The provision of purely metacognitive prompts did not, however, improve learning outcomes. Only the groups who had received cognitive, or a combination of cognitive and metacognitive, prompts learned more than the control group. This effect was mediated by cognitive learning strategies. The learners in the successful groups did not perceive the prompted learning strategies as more helpful than the learners of the group without prompts. It can be concluded that cognitive prompts—alone or in combination with metacognitive prompts—are an effective means to foster learning. However, additional means should be employed in order to convince the learner of the usefulness of such prompts.     

Effects of computer support,collaboration, and time lag on performance self-efficacy and transfer of training: A longitudinal meta-analysis

This meta-analysis (29 studies, k = 33, N = 4158) examined the longitudinal development of the relationship between performance self-efficacy and transfer before and after training. A specific focus was on training programs that afforded varying degrees of computer-supported collaborative learning (CSCL). Consistent with social cognitive theory, results suggested positive population correlation estimates between self-efficacy and transfer before (ρ = 0.31) and after (ρ = 0.39) training, and thus a small but positive increase. Three boundary conditions were estimated. First, effect sizes were higher in trainings with rather than without computer support. Second, effect sizes were higher in trainings without rather than with collaboration. Third, time lag had marginal effects. These findings are discussed in terms of their implications for theories of complex social and computer-mediated learning environments and their practical significance for scaffolding technology-enhanced learning and interaction.     

Attachment in institutionalized children: A review and meta-analysis

In this article we review the literature on attachment patterns in institutionalized children and then perform a meta-analysis on data from 10 attachment studies involving 399 children in institutional settings. We computed the overall attachment distribution of secure, insecure, and disorganized rates and explored the effect of a set of moderating variables (i.e., country of institutionalization, attachment assessment procedure, age at entry, and age at assessment). To overcome bias related to the small number of studies, we conducted both classical and Bayesian meta-analysis and obtained comparable results. Distribution of children's attachment patterns was: 18% secure, 28% insecure, and 54% disorganized/cannot classify. Compared to their family-reared peers, children living in an institution were found to be at greater risk for insecure and disorganized attachment, with a similar medium effect size for both distributions (d = 0.77 and d = 0.76, respectively). The following moderating variables were associated with insecure attachment: representational assessment procedures (d = 0.63) and Eastern European countries of origin (d = 1.13). Moderators for disorganized attachment were: Eastern European countries of origin (d = 1.12), age at institution entry before the first birthday (d = 0.93), and age at assessment under three years of age (d = 0.91). Implications for child development and policies are discussed.     

What is the effect of talking heads in educational videos with different types of narrated slides?

Video-based learning plays an increasingly important role and thus the optimal design of video-based learning materials attracts the attention of scientists and practitioners alike. In this context, producers of educational videos often include a talking head in their videos, although theory (e.g., cognitive theory of multimedia learning) also suggests potential disadvantages for this format. Since talking heads attract a lot of visual attention, further empirical research is necessary to investigate whether a talking head can hinder learning, especially presented next to graphic-based learning content. To address this research gap, we conducted two online experiments to investigate the effects of a talking head in educational videos with narrated slides (short slideshow lectures) on learning outcomes (i.e., factual knowledge acquisition) and participants’ subjective ratings of the learning material (e.g., perceived learning). In Experiment 1 (N = 96), we varied whether the instructor’s talking head was present or absent in the videos as a between-factor, and whether the visual content on the slides was graphic-based (pictures, diagrams, maps) or text-based (bullet points) as a within-factor (slide type). In Experiment 2 (N = 184), we additionally varied as a between-factor whether the contents appeared sequentially or statically all at once (presentation type). Our results showed that the talking head did not affect learning outcomes, regardless of slide type and presentation type of the videos suggesting that the inclusion of a talking head offers neither clear advantages nor disadvantages. Potential explanations for the findings and directions for future research are discussed.     

The effectiveness of educational technology applications for enhancing mathematics achievement in K-12 classrooms: A meta-analysis

The present review examines research on the effects of educational technology applications on mathematics achievement in K-12 classrooms. Unlike previous reviews, this review applies consistent inclusion standards to focus on studies that met high methodological standards. In addition, methodological and substantive features of the studies are investigated to examine the relationship between educational technology applications and study features. A total of 74 qualified studies were included in our final analysis with a total sample size of 56,886 K-12 students: 45 elementary studies (N = 31,555) and 29 secondary studies (N = 25,331). Consistent with the more recent reviews, the findings suggest that educational technology applications generally produced a positive, though modest, effect (ES = +0.15) in comparison to traditional methods. However, the effects may vary by educational technology type. Among the three types of educational technology applications, supplemental CAI had the largest effect with an effect size of +0.18. The other two interventions, computer-management learning and comprehensive programs, had a much smaller effect size, +0.08 and +0.07, respectively. Differential impacts by various study and methodological features are also discussed.     

Enhancing self-regulated learning by writing learning protocols

Learning protocols are a self-guided way of writing that allows for elaboration and reflection on learning content. In an experimental study (N = 103), we supported protocol writing with prompts to elicit important strategies as postulated by a cyclical model of self-regulated learning. Students received either (a) no prompts, (b) cognitive prompts, (c) metacognitive prompts, (d) mixed prompts without, or (e) including prompts for planning of remedial strategies. Prompting all essential sub-processes of self-regulated learning (group e) fostered students' comprehension best. Thus, with appropriate support, writing can serve as a beneficial medium helping students to self-regulate their understanding of subject matter.
