Students' issues dealing with reflection tasks, especially with inclined mirror lines, are widely known. Previous research conducted with primary school students mainly focussed on task difficulty and students' outcomes, especially their errors of reflection. Little is known about which not obviously sustainable understanding of reflection leads…

Purpose: This study examined language group differences in English syntactic knowledge based on performance on a sentence repetition task. Method: Fourth and sixth grade students who were monolinguals (n = 30), early bilinguals (i.e., simultaneous; n = 27), or late bilinguals (i.e., sequential; n = 29) completed an English sentence repetition…

Language and numerical development are associated in early childhood. In the present study, we focused on the association of the development of children's cardinality understanding of small numbers and their knowledge on unspecific quantifiers (i.e., many, a few). In a longitudinal study, we pursued the research question whether children's…

In the past decade, many scholars conducted research concerning cultural content, policy changes, and other issues in the field of EFL textbook evaluation in China. However, a limited number of studies shift their attention to task types used in EFL textbooks. This study employs Nunan's (1999) task taxonomy to investigate how task types are…

Fifty-one 23-to-55-month-old-infants faced two apparatuses that required the use of a rigid (box apparatus) or flexible (hose apparatus) stick-like tool to retrieve a toy stuck inside. Before attempting the extraction, however, they had to pick the only one tool (of three) on display that had the appropriate rigidity/flexibility to be effective.…

Purpose: Verbal fluency, a task frequently employed in neuropsychological assessment, provides important word productivity data but little information about subjective effort associated with demand monitoring and resource allocation. In two experiments, this study investigated the effects of task variables (semantic vs. phonemic cues; alternating…

This study aims to determine the relationships between mental effort and the use of learner controls while working with instructional software. Various versions of instructional software including control components were developed to examine this relationship. Twenty-four secondary school students participated in the study and studied with…

Although there is a broad consensus that both the procedural and declarative memory systems play a crucial role in language learning, use, and knowledge, the mapping between linguistic types and memory structures remains underspecified: by default, a dual-route mapping of language systems to memory systems is assumed, with declarative memory…

In this paper, we present parts of an online qualitative research project which lasted a whole semester about the understanding of real numbers by sixty first-year Greek mathematics undergraduate students during the COVID-19 pandemic. We focus on the distinction between rational and irrational numbers and their location on the number line using…

This study examines whether second language (L2) learners predict upcoming language prior to the verb in Japanese. Taking the dependency involving negative polarity adverbs -- "zenzen" 'at all' and "amari" '(not) very' -- as a test case, this study examined whether Japanese native speakers and L2 learners of Japanese, aided by…

Purpose: Children with speech sound disorders have more difficulties producing speech sounds accurately than same-age peers. In addition, they often have difficulties with speech perception, and weaker phonological awareness skills than their peers and are at risk for negative long-term academic and socio-emotional outcomes. In this tutorial, we…

We examined the impact of images on novel word learning and consolidation, in a conceptual replication of Liu and Van Hell (2020). After participants had learned one set of novel words with definitions and images on Day 1 (remote words) and a different set on Day 2 (recent words), they judged the semantic relatedness of word pairs on Days 2 and 8…

The main purpose of this study was to investigate the consistency of pictorial representations of the atomic structure drawn by students on the basis of particular quantum numbers' characteristics. Participants were 192 students of the 12th grade of secondary Greek schools. This study's instrument, a paper-and-pencil assessment tool, included four…

Maurice Sendak's picture book Where the "Wild Things Are" was investigated as a means of emotion recognition in preschool children. Sixty-six children and 60 adults participated in two tasks. The first was a book task, requiring identification of emotions in three target pictures, in three conditions. The visual condition presented the…

In this paper, I share an activity that reinforces students' understanding of translations, reflections, and rotations via body movement. As a result of this activity, students gain a different perspective compared to previous explorations on paper, communicate mathematics, and visualize transformations as rigid motions on the plane. Furthermore,…
