This paper examined the effects of training in creative problem-solving on intelligence. We revisited Stankov's report on the outcomes of an experiment carried out by R. Kvashchev in former Yugoslavia that reported an IQ increase of seven points, on average, across 28 tests of intelligence. We argue that previous analyses were based on a…

While more diverse children's literature about youth activism is available than ever before, popular picturebooks often perpetuate problematic tropes about the Civil Rights Movement. In this article, we conduct a critical content analysis of the award-winning picturebook "The Youngest Marcher" and contrast the book's content to a…

School history textbooks provide an important source of information for learners of history. Textbook narratives of a nation's past often present a limited frame of reference, which impedes the aim of teaching history from multiple perspectives. This article examines the representation of the Dutch Revolt in two Dutch and two Flemish history…

Methods and approaches for teaching engineering disciplines are evolving to adapt to the needs of companies and society. Engineering Design is one of the areas most influenced by such changes and constantly striving to develop more effective and efficient strategies to prepare the soon-to-be engineers to face the challenges of a real working…

Purpose: The goal of this study was to determine whether the results obtained from a 25-utterance conversational language sample were as reliable as those obtained from a 50-utterance sample. Method: Robust conversational language samples from 220 children with typically developing language (106 boys, 114 girls) ranging in age from 3;2 to 7;10…

Signals (or cues) are added to multimedia learning materials to guide learners' attention to critical elements of the materials. Yet, research on signaling has produced mixed findings on learning outcomes. On the one hand, some studies have reported positive effects of signaling on the performance of learning outcomes (e.g., Jamet in Hum Behav…

This study compared generating information about food to viewing and verbally producing that information for learning and transfer. Specifically, during training, a list of food items was shown, and some participants generated either real calories (Experiment 1) or fabricated prices (Experiment 2) associated with those foods with feedback provided…

Ordinary kriging, a spatial interpolation technique, is commonly used in social sciences to estimate neighborhood attributes such as physical disorder. Universal kriging, developed and used in physical sciences, extends ordinary kriging by supplementing the spatial model with additional covariates. We measured physical disorder on 1,826 sampled…

In this exploratory study, I investigate the relationship between age, knowledge, and creativity in mathematics, by looking at to what extent does grade level, controlled for mathematical achievement, influence mathematical creativity and what characterizes the relationship between grade level, mathematical achievement and mathematical creativity.…

In order to obtain good grades, students involve themselves in hard work according to the best of their ability, yet an experiential learning project makes it even harder to attain the grades that the students are aiming for. Researches have shown that students are generally optimistic about their grades, yet no research has been found in Pakistan…

This study evaluated associations between similarity in personal values, accuracy of values perceptions, and relationship closeness among emerging adults and their mothers (dyads = 99). Contrary to previous studies, values similarity and accuracy were largely unrelated to relationship closeness. This was reinforced by Latent Profile Analysis…

The nature of the learning that occurs with real versus replicated objects and environments is an important topic for museums and science centers. Our comparative, exploratory study addressed this area through an investigation of family visits to two different settings: an operating permafrost research tunnel, and a replica of this permafrost…

This article shares analysis regarding quantum mechanics students' metarepresentational competence (MRC) that is expressed as they engaged in solving an expectation value problem, which involves linear algebra concepts. The particular characteristic of MRC that is the focus of this analysis is students' critiquing and comparing the adequacy of…

Recent work on measuring growth with categorical outcome variables has combined the item response theory (IRT) measurement model with the latent growth curve model and extended the assessment of growth to multidimensional IRT models and higher order IRT models. However, there is a lack of synthetic studies that clearly evaluate the strength and…

Undergraduate research benefits students by strengthening skills, providing professional growth, and improving retention. Yet significant barriers exist, including low awareness of opportunities, restrictive cultural norms, and resource constraints. The proliferation of online education potentially increases barriers, both real and perceived. This…
