Should you show me the money? Concrete objects both hurt and help performance on mathematics problems

How do concrete objects that cue real-world knowledge affect students' performance on mathematics word problems? In Experiment 1, fourth- and sixth-grade students (N = 229) solved word problems involving money. Students in the experimental condition were given bills and coins to help them solve the problems, and students in the control condition were not. Students in the experimental condition solved fewer problems correctly. Experiment 2 tested whether this effect was due to the perceptually rich nature of the materials. Fifth-grade students (N = 79) were given: perceptually rich bills and coins, bland bills and coins, or no bills and coins. Students in the perceptually rich condition made the most errors; however, their errors were least likely to be conceptual errors. Results suggest that the use of perceptually rich concrete objects conveys both advantages and disadvantages in children's performance in school mathematics.     

How to understand what you don't believe: Metacognitive training prevents belief-biases in multiple text comprehension

Prior beliefs often bias the comprehension of multiple science-related texts such that belief-consistent texts are better comprehended compared to belief-inconsistent texts (text-belief consistency effect). Two experiments were conducted to investigate whether a metacognitive strategy training focusing on belief-biasing validation processes can reduce the text-belief consistency effect in multiple text comprehension. Participants in the control condition received the PQ4R training as a well-situated and effective reading skill training that increases receptive elaborative processing. In Experiment 1 (n = 39) and Experiment 2 (n = 53) participants receiving a metacognitive strategy training achieved a similar level of comprehension of belief-consistent and belief-inconsistent texts, whereas a text-belief consistency effect was found in the PQ4R condition. These results indicate that a training focusing on belief-biasing validation processes prepare readers for the challenges to comprehend belief-relevant multiple texts, whereas strategies that foster receptive processing of information are not sufficient in the context of controversially discussed topics.     

Fostering the use of pedagogical practices among teachers to support elementary students’ motivation to write

Based on self-determination theory, this research aimed at evaluating the effectiveness of the CASIS professional development (PD) program for fostering (1) teachers’ use of five recommended pedagogical practices during a writing lesson and (2) students’ motivational resources (intrinsic, identified, and controlled regulations) toward writing. Two quasi-experimental studies with two-time points were conducted among preservice (Study 1, n = 32) and inservice (Study 2, n = 111) elementary teachers and their students (Study 1, n = 559; Study 2, sample 1, n = 1779; sample 2, n = 1471). In both studies, the CASIS PD program appeared to foster the use of two of the five recommended pedagogical practices. For the other three, some effects were observed in one study but were not always reproduced in the other. Although the CASIS PD program fostered greater use of the pedagogical practices, this effect did not always translate directly to the students’ motivational resources. However, some significant differences were observed between students of the CASIS and the control groups on identified and controlled regulations, as a function of the socioeconomic background of the schools in which teachers and students were sampled. The results are discussed in light of past research and relevant theories.     

How a picture facilitates the process of learning from text: Evidence for scaffolding

Three experiments were conducted to study on a more fine-grained level how processing a picture facilitates learning from text. In Experiment 1 (N = 85), results from a drawing task revealed that the global spatial structure of a pulley system picture was extracted even from its brief inspection (for 600 ms, 2 s). In Experiment 2 (N = 105), students who initially inspected the pulley system picture (for 600 ms, 2 s, or self-paced) had better comprehension of the system's functions and made more eye movements in line with the system's global spatial structure when listening to text than students who listened to text only. In Experiment 3 (N = 39), students who first saw the picture (for 2 s) processed written text of the pulley system's spatial structure more efficiently than students who read text only. Results suggest that global spatial information extracted from the picture was used as a mental scaffold to facilitate mental model construction.     

What kinds of perceptions and daily learning behaviors promote students' use of diagrams in mathematics problem solving?

This study investigated factors promoting the use of self-constructed diagrams by examining students' perceptions and daily class activities, and comparing Japanese (n = 291) and New Zealand (n = 323) students. Algebra word problems and a questionnaire were administered. The results revealed that the New Zealand students used diagrams more often and scored higher than their Japanese counterparts. Lack of confidence and perceptions of difficulty in diagram use, and viewing diagrams more as a strategy that teachers use, were found to link with lower use. Possible ways of promoting diagram use in math word problem solving are discussed.     

The role of learning approaches in explaining the distinct learning behaviors presented by American and Chinese undergraduates in the classroom

The distinct learning behaviors observed in the classroom between American and Chinese students have been discussed extensively in literature. The authors speculated that learning approaches (structure-oriented approach vs. depth-oriented approach) might play a role in explaining different behavioral traits presented by American and Chinese students. Two measures assessing learning approaches and learning behaviors in the classroom were administered to two samples: American undergraduates (n = 199) and Chinese undergraduates (n = 265). The results revealed that American undergraduates appeared to be more “active” in the classroom compared to Chinese undergraduates. Chinese undergraduates scored significantly higher on the structure-oriented approach, but did not differ significantly in the depth-oriented approach compared to American undergraduates. The results also indicated that the structure-oriented approach mediated the relationship between cultural group and learning behavior, and thus suggest that the structure-oriented learning approach might partially explain the distinct behavioral traits presented by American and Chinese students in the classroom.     

Benefits of emotional design in multimedia instruction

Emotional design of multimedia instruction involves making the essential elements in the lesson's graphics more appealing, such as by rendering them with human-like features and with distinct, appealing colors (Um, Plass, Hayward, & Homer, 2012). College students received an 8-slide multimedia lesson on how a virus causes a cold for 5 min (Experiment 1) or for as long as they wanted (Experiment 2). For the control group, the graphics consisted of simple black-and-white drawings in which the host cell was represented as a large circle, and the virus was represented as a small circle with small spikes on the outside and a rectangle on the inside. For the enhanced group, the graphics were redrawn to render the host cell as a red face with expressive eyes (registering surprise, fear, and sickness at various stages in the process), and the virus as a blue face with fierce eyes and with a green dot at the end of each of the blue tentacles surrounding the virus face. The enhanced group performed better than the control group on a subsequent learning test (d = 0.69 in Experiment 1, d = 0.65 in Experiment 2) and gave higher effort ratings in Experiment 1 (d = 0.65) but not in Experiment 2 (d = −0.10). The findings are generally consistent with the cognitive affective theory of learning with media, and point to the importance of incorporating motivation into cognitive theories of multimedia learning.     

Materialism does not pay: Materialistic students have lower motivation,engagement, and achievement

The aim of this study was to examine how materialism, or the focus on acquiring money and material possessions, is associated with students’ academic engagement and achievement via their motivational regulation (amotivation, controlled motivation, and autonomous motivation). Study 1 (n = 606 secondary students) was a cross-sectional study which found that materialism was negatively associated with engagement. This association was partially mediated by amotivation. Study 2 (n = 404 secondary students) was a longitudinal study which found that Time 1 materialism was negatively associated with Time 2 engagement and Time 3 academic achievement via amotivation. Results of the two studies provide converging lines of evidence that materialism is negatively associated with key indicators of learning. Students with high levels of materialism have lower levels of engagement and achievement, and these associations are partially mediated by amotivation. Theoretical and practical implications are discussed.     

Elementary mathematics teachers’ judgment accuracy and calibration accuracy: Do they predict students’ mathematics achievement outcomes?

In this study we investigated whether elementary mathematics teachers’ knowledge of their students, as reflected in both the accuracy and confidence with which they are able to estimate their students’ task-specific performance on sets of mathematics problems, predicted students’ overall mathematics achievement. Thirty-nine teachers made predictions about the performance of a random sample of target students (n = 150) in their classrooms on sets of “easy” and “difficult” multiplication and division problems. Teachers also provided confidence ratings for those judgments. From these data, indicators of teachers’ judgment accuracy, judgment confidence and calibration accuracy (a measure of metacognitive monitoring) were then related to all of their students’ (n = 834) performance on year-end standardized mathematics achievement tests. Multilevel analyses indicate that teachers’ calibration accuracy, but not their task-specific judgment accuracy, significantly predicted students’ mathematics achievement. Implications for future research on teacher knowledge as well as professional development programs are discussed.     

Do preservice teacher education candidates’ implicit biases of ethnic differences and mindset toward academic ability change over time?

Teachers' implicit biases about ethnic differences in student achievement and teachers' mindsets have been associated with significant differences in their students’ achievement. In two studies (N = 313; N = 57) with preservice teachers undertaking a three-year teacher education programme aimed at promoting social justice, we found that third-year students showed significantly less implicit ethnic achievement bias and reduced fixed mindsets compared to the first-year preservice teachers. Students from the ethnic minority were found to have the least bias, but still associated student achievement more with the ethnic majority group. It is concluded that more is needed to reduce implicit biases and develop a growth mindset among our preservice teachers.     

Infants' Perception of Emotion From Body Movements

Adults recognize emotions conveyed by bodies with comparable accuracy to facial emotions. However, no prior study has explored infants' perception of body emotions. In Experiment 1, 6.5‐month‐olds (n = 32) preferred happy over neutral actions of actors with covered faces in upright but not inverted silent videos. In Experiment 2, infants (n = 32) matched happy and angry videos to corresponding vocalizations when the videos were upright but not when they were inverted. Experiment 3 (n = 16) demonstrated that infants' performance in Experiment 2 was not driven by information from the covered face and head. Thus, young infants are sensitive to emotions conveyed by bodies and match them to affective vocalizations, indicating sophisticated emotion processing capabilities early in life.     

The Development of Selective Copying: Children's Learning From an Expert Versus Their Mother

This study tested the prediction that, with age, children should rely less on familiarity and more on expertise in their selective social learning. Experiment 1 (N = 50) found that 5‐ to 6‐year‐olds copied the technique their mother used to extract a prize from a novel puzzle box, in preference to both a stranger and an established expert. This bias occurred despite children acknowledging the expert model's superior capability. Experiment 2 (N = 50) demonstrated a shift in 7‐ to 8‐year‐olds toward copying the expert. Children aged 9–10 years did not copy according to a model bias. The findings of a follow‐up study (N = 30) confirmed that, instead, they prioritized their own—partially flawed—causal understanding of the puzzle box.     

Sensitivity to Visual-Tactile Colocation on the Body Prior to Skilled Reaching in Early Infancy

Two experiments examined perceptual colocation of visual and tactile stimuli in young infants. Experiment 1 compared 4- (n = 15) and 6-month-old (n = 12) infants’ visual preferences for visual-tactile stimulus pairs presented across the same or different feet. The 4- and 6-month-olds showed, respectively, preferences for colocated and noncolocated conditions, demonstrating sensitivity to visual-tactile colocation on their feet. This extends previous findings of visual-tactile perceptual colocation on the hands in older infants. Control conditions excluded the possibility that both 6- (Experiment 1), and 4-month-olds (Experiment 2, n = 12) perceived colocation on the basis of an undifferentiated supramodal coding of spatial distance between stimuli. Bimodal perception of visual-tactile colocation is available by 4 months of age, that is, prior to the development of skilled reaching.     

Learning by writing explanations: Is explaining to a fictitious student more effective than self-explaining?

Research has demonstrated that oral explaining to a fictitious student improves learning. Whether these findings replicate, when students are writing explanations, and whether instructional explaining is more effective than other explaining strategies, such as self-explaining, is unclear. In two experiments, we compared written instructional explaining to written self-explaining, and also included written retrieval and a baseline control condition. In Experiment 1 (N = 147, between-participants-design, laboratory experiment), we obtained no effect of explaining. In Experiment 2 (N = 50, within-participants-design, field-experiment), only self-explaining was more effective than our control conditions for attaining transfer. Self-explaining was more effective than instructional explaining. A cumulating meta-analysis on students’ learning revealed a small effect of instructional explaining on conceptual knowledge (g = 0.22), which was moderated by the modality of explaining (oral explaining > written explaining). These findings indicate that students who write explanations are better off self-explaining than explaining to a fictitious student.     

Learning executive function skills by playing focused video games

The objective of the present study was to determine whether it is possible to design a video game that could help students improve their executive function skill of shifting between competing tasks and the conditions under which playing the game would lead to improvements on cognitive tests of shifting. College students played a custom video game, Alien Game, which required the executive function skill of shifting between competing tasks. When students played for 2 h over 4 sessions they developed significantly better performance on cognitive shifting tests compared to a control group that played a different game (d = 0.62), but not when they played for 1 h over 2 sessions. Students who played Alien Game at a high level of challenge (i.e., reaching a high level in the game) developed significantly better performance on cognitive shifting tests compared to controls when they played for 2 h (Experiment 1, d = 1.44), but not when they played for 1 h (Experiment 2). Experiment 3 replicated the results of Experiment 1 using an inactive control group, showing that playing Alien Game for 2 h resulted in significant improvements in shifting skills (d = 0.78). Results show the effectiveness of playing a custom-made game that focuses on a specific executive function skill for sufficient time at an appropriate level of challenge. Results support the specific transfer of general skills theory, in which practice of a cognitive skill in a game context transferred to performance on the same skill in a non-game context.     

Child maltreatment among boy and girl probationers: Does type of maltreatment make a difference in offending behavior and psychosocial problems?

This study examined differences in offending behavior and psychosocial problems between juvenile offenders who have been sexually abused (n = 231), physically abused (n = 1,568), neglected (n = 1,555), exposed to multiple forms of maltreatment (n = 1,767), and non-victims (n = 8,492). In addition, the moderating effect of gender in the association between type of maltreatment and offending behavior/psychosocial problems was examined. Results showed that violent offenses were more common in victims of physical abuse and victims of multiple forms of abuse than in non-victims, both in boys and girls. In boys, sexual offenses were far more common in victims of sexual abuse than in victims of other or multiple forms of maltreatment or in non-victims. In girls, no group differences were found in sexual offending behavior. For both boys and girls, externalizing problems were relatively common in victims of physical abuse and neglect whereas internalizing problems were relatively common in victims of sexual abuse. In victims of multiple forms of maltreatment, both internalizing and externalizing problems were relatively common. Implications for clinical practice are discussed.     

Mini managers: Children strategically divide cognitive labor among collaborators,but with a self-serving bias

Strategic collaboration according to the law of comparative advantage involves dividing tasks based on the relative capabilities of group members. Three experiments (N = 405, primarily White and Asian, 45% female, collected 2016–2019 in Canada) examined how this strategy develops in children when dividing cognitive labor. Children divided questions about numbers between two partners. By 7 years, children allocated difficult questions to the skilled partner (Experiment 1, d = 1.42; Experiment 2, d = 0.87). However, younger children demonstrated a self-serving bias, choosing the easiest questions for themselves. Only when engaging in a third-party collaborative task did 5-year-olds assign harder questions to the more skilled individual (Experiment 3, d = 0.55). These findings demonstrate early understanding of strategic collaboration subject to a self-serving bias.     

Effects of creating video-based modeling examples on learning and transfer

Two experiments investigated whether acting as a peer model for a video-based modeling example, which entails studying a text with the intention to explain it to others and then actually explaining it on video, would foster learning and transfer. In both experiments, novices were instructed to study a text, either with the intention of being able to complete a test (condition A), or being able to explain the content to others (condition B and C). Moreover, students in condition C actually had to explain the text by creating a webcam-video. In Experiment 1 (N = 76 secondary education students) there was no effect of study intention on learning (A = B), but explaining during video creation significantly fostered transfer performance (C > B; C > A). In Experiment 2 (N = 95 university students), study intention did have an effect on learning (C > A; B > A), but only actual video creation significantly fostered transfer performance (C > A).     

Instructional methods and languages in class: A comparison of two teaching approaches and two teaching languages in the field of intercultural learning

The article presents the results of a quasi-experimental intervention study with a 2 × 2 factorial design. We implemented a problem-based intercultural learning unit in four secondary schools (grades 9 to 12) and varied the teaching approach (analytical/affective-experiential) and the language of instruction (German/English). The learning unit covered six 45-min lessons and was conducted in nine school courses (n = 143). Five additional school courses (n = 66) served as a control group. In all experimental groups, students engaged with critical incidents. These were either analysed (analytical focus) or acted out as role plays (affective-experiential focus). In addition, students analysed film clips (analytical focus) or participated in a simulation game (affective-experiential focus). The experimental groups outperformed the control group in the post-test, which required the analysis of critical incidents. Both teaching approaches were equally effective; however, students evaluated affective-experiential learning more positively. Using a foreign language for teaching did not impair performance.
