Studies have shown that course participation and academic performance are key factors in defining the success of online education, but much remains unknown regarding how best to define the success of online K-12 after-school education that are popular in Asian countries. To address this issue, we used a longitudinal clustering approach to analyze…

The ruler is the standard measuring instrument used for measuring lengths. However, measuring lengths with a ruler is a challenge for children. For this reason, this study explores how children who have not received specific school instruction on its use, measure lengths with a conventional ruler. The relative object-ruler position, the strategy…

This matched-sample study investigates the use of a wide range of texts of varying--and often challenging--complexity to promote fluency for students experiencing below grade level achievement. We designed a repeated-reading protocol called 'Read Like Us', and performed a pilot implementation in small groups with third- and fourth-grade students…

Previous research has not adequately explored students' behavioral processes when addressing computational thinking (CT) problems of varying difficulty, limiting insights into students' detailed CT development characteristics. This study seeks to fill this gap by employing gamified CT items across multiple difficulty levels to calculate…

Persistence has proven to be a great challenge in online learning environments. Gaming and interactivity have been suggested as essential features in reducing dropout and increasing persistence in online learning. Yet in interactive game-based learning environments, persistence in moving forward in the game may come at the expense of investing in…

The purpose of the study was to assess the volume of academic vocabulary in elementary grades disciplinary textbooks. Academic vocabulary was examined in a corpus of best-selling elementary grades textbooks in three disciplinary areas--science, mathematics, and social studies. Academic words in texts were determined through automated procedures…

The researchers explored the conceptual complexity of vocabulary in contemporary elementary-grades core science program textbooks to address two research questions: (1) Can a progression of concepts' complexity level be described across grades? (2) Was there gradual developmental growth of the most complex concepts' networks of associated concepts…

Spelling is a language problem-space, not only a school subject. Successful spelling demands going beyond letter to sound mapping and gaining access to a full representation of the orthographic structure of words. We traced bilingual Catalan/Spanish speakers' spelling performance in Catalan across elementary school in two tasks: isolated words to…

This dissertation reports the results of a research project that examined the effects of varying rates of reinforcement on students' math performance and assignment preference. The relationship between students' instructional level and the rate of reinforcement threshold for influencing assignment preference was also explored. Participants were…

The two studies reported on in this paper examine the features of words that distinguish students' performances on vocabulary assessments as a means of understanding what contributes to the ease or difficulty of vocabulary knowledge. The two studies differ in the type of assessment, the types of words that were studied, and the grade levels and…

The purpose of this meta-analysis was to examine the relation between mathematics anxiety (MA) and mathematics performance among school-aged students, and to identify potential moderators and underlying mechanisms of such relation, including grade level, temporal relations, difficulty of mathematical tasks, dimensions of MA measures, effects on…

Purpose: As children develop skills in writing across academic contexts, clinicians and educators need to have a fundamental understanding of typical writing development as well as valid and reliable assessment methods. The purpose of this study was to examine the progression of linguistic elements in school-age children's narrative and expository…

This study investigated the complexity of leveled passages used in four classroom reading assessments. A total of 167 passages leveled for Grades 1-6 from these assessments were analyzed using four analytical tools of text complexity. More traditional, two-factor measures of text complexity found a general trend of fairly consistent across-grade…

The present paper investigates differences in the process of mastering the four basic arithmetic operations (addition, subtraction, multiplication and division) between Flemish and Chinese children from Grade 3 till Grade 6 (i.e. from 8 to 11 years old). The results showed, firstly, that Chinese students outperformed Flemish students in each grade…

The main aim of this study was to develop standardised tests that assess some of the most important spelling skills for children in primary school: sound-letter mappings (non-lexical spelling) and word spelling accuracy (lexical spelling). We present normative comparison data for children in Grades 1-7 as well as measures of validity and…
