The present study sought to investigate the friendship formation of ethnic in-and out-group friendships, as well as differences in stability and quality, while accounting for the network structure (such as the tendency to befriend friends of friends). We analyzed longitudinal data from 770 students from 42 Austrian primary school classes collected…

With accelerating advances in artificial intelligence, it is clear that introducing K-12 students to AI is essential for preparation to interact with and potentially develop AI technologies. To succeed as the workers, creators, and innovators of the future, we argue students should encounter core concepts of AI as early as elementary school.…

The primary purpose of this study is to investigate the degree to which register knowledge, register-specific motivation, and diverse linguistic features are predictive of human judgment of writing quality in three registers--narrative, informative, and opinion. The secondary purpose is to compare the evaluation metrics of register-partitioned…

Recent research has focused on evaluating the relation between mindset and reading achievement. We used exploratory factor mixture models (E-FMMs) to examine the heterogeneity in reading achievement and mindset of 650 fourth graders with reading difficulties. To build E-FMMs, we conducted confirmatory factor analyses to examine the factor…

With the increasing importance of teaching STEM to young students, the engineering design process (EDP) has become a popular learning platform in K-12 STEM education. The engineering design process guides students in solving engineering problems, but there is a lack of understanding of how students utilize this process. In this study, we explored…

The Cross-Classified Mixed Effects Model (CCMEM) has been demonstrated to be a flexible framework for evaluating reliability by measurement specialists. Reliability can be estimated based on the variance components of the test scores. Built upon their accomplishment, this study extends the CCMEM to be used for evaluating validity evidence.…

The activity described here was designed to center on the observation of circadian rhythms in plants through the example of growing beans. The aim was to develop students' skills of systematic observation of various variables in the long-term. Our study took place at a Science and Arts Center with 17 gifted students in the third and fourth grades…

The assumption that multi-grade learning enhances and sustains positive self-concept is widespread, although neither theory nor empirics have yet allowed for firm conclusions. This paper reports on a representative longitudinal study of multi-grade learning in grades 3 and 4 comparing the development of students' self-concept in reading in…

Designed as action research, this qualitative study aims to develop the informational text writing skills of gifted students through the strategies of "all about" books and "biography writing frames". The study group of the research consists of 21 gifted 4th-grade students studying in the field of general mental ability in a…

This study examined the influence of addition and subtraction practice embedded within a word-problem intervention for Grade 3 students experiencing word-problem difficulty. Students (N = 448) were randomly assigned to one of two variants of a word-problem intervention or a business-as-usual comparison condition. Within the word-problem…

When preservice teachers were no longer able to visit schools due to the pandemic, their university professor partnered with an alum who teaches fourth grade to design and implement virtual book clubs. The preservice teachers created book trailers for the fourth graders to view and choose from for their book club. The groups connected using a…

This study aimed to determine fourth grade primary school students' self-regulated learning strategies and successes in mathematics course in terms of socio-economic level. A cross-section scanning model was used in the study. The sample of the study was determined by the random sampling technique. The sample consisted of 65 students studying in 2…

One of the goals of science, technology, engineering, and mathematics (STEM) education is to promote students' understanding of and interest in STEM careers. However, young students often hold stereotypical perceptions of STEM professionals. This study aimed to apply two newly developed checklists to explore upper elementary students' perceptions…

This study examines the convergent validity of the Physical Activity Questionnaire for Children (PAQ-C) for assessing moderate-to-vigorous and total physical activity (PA) in school children. 430 participants (51.6% girls) aged 9-12 years provided valid accelerometer data (wGT3X-BT) and completed the PAQ-C. Convergent validity was assessed using…

This article describes the two types of reasoning in fraction conceptions that students often use, "gap" and "missing piece," and one that the authors aspire their students to reach, "residual." Each of these types of reasoning are underpinned by a different conception of fractions. Students who use "gap…
