Sexual health communication in adolescence is important for sexual well-being. With limited empirical work utilizing longitudinal methodologies, this study aimed to investigate how the frequency of sexual communication with parents, peers, and dating partners changes across adolescence and varies based on sex, race/ethnicity, and sexual…

Years and Centuries are the measurement units used to quantify a longer time duration, while subtraction is the operation required to determine the duration based on two given time points. However, subtraction of time is a difficult skill to be mastered by many elementary students. To identify the root cause of the student's failure in performing…

This study explores how the chronotope, a particular time-space, of a collective in-time experience through music takes shape through the individual and interconnected actions and responses of a teacher and students in joint music-making. The dataset consists of video recordings of a joint music-making lesson (45 min) and the interviews of the…

This large-scale study characterizes the algebraic learning of a cohort of nearly 800 French students during the last year of middle school (9th grade, 14-15 years old) and examines their evolution in relation to the composition of the classes to which the students belong. Based on the Anthropological Theory of the Didactic (ATD), the study is…

Even with the increase in virtual learning, there remains a stigma that virtual schools are not successfully supporting students based on traditionally lower graduate rates and state assessment data. The problem is statewide educational decision-makers lacked an understanding of the prior academic performance, specifically credit attainment, among…

Considering the negative situations faced by the migrating societies, it is known that the language and culture factors exert a stronger influence on the mathematics course than the other undesirable conditions. From this perspective, it is known that the mathematical performance of individuals is likely to increase by placing the concept of…

The current study examined associations between proactive and reactive aggression and disciplinary actions in an academic year among middle school-age youth at Time 1 (Fall) and 6-month later (Spring) and evaluated school attachment as a moderator of these links. Findings indicated that reactive, not proactive, aggression was robustly positively…

We compare poor-performing and normal-performing decoders' processing times on real words, pseudo-homophones, and nonwords (Study 1), and evaluate how a processing time difference is associated with rates of decoding development (Study 2). Over 800 sixth and seventh graders took an online reading component battery, which included a decoding test,…

Mathematics education researchers suggest that providing the opportunity to struggle with important mathematics (SOS) is a necessary component of lessons in order for students to conceptually understand mathematics. There are many ways to promote and support SOS, yet very few lessons demonstrate SOS in today's middle grades classrooms. This study…

Background: Student absenteeism is a growing concern in U.S. schools. In 2015-16, states' chronic absenteeism rates -- defined as rates of students missing 10% or more of a school year -- ranged from 9.5% to 26.9% of students (U.S. Department of Education, n.d.). Although abundant research exists on absenteeism and its effects on student outcomes,…

This conceptual paper discusses two frameworks, developed independently by the lead author, that will provide the conceptual foundation for the identification and evaluation of mental computation strategies students demonstrate during an upcoming research project entitled Mental Computation in Year 5. These frameworks will be used by the lead…

Background: The excessive use of Internet-based technologies has received a considerable attention over the past years. Despite this, there is relatively little research on how general Internet usage patterns at and outside of school as well as on weekends may be associated with mathematics achievement. Moreover, only a handful of studies have…

The examples used in the teaching-learning process of mathematics have a crucial role in fostering conceptual understanding, and some variables can affect instructors' qualified example usage. This longterm study focused on mathematics teachers' exemplification process in face-to-face and online learning environments. In this regard, the change in…

Extensive reading (ER) provides young English language learners (YELLs) many benefits, including the sustainable development of writing (e.g., the reading-writing relationship). However, this area is underresearched. To address this, this quasi-experimental study investigated the effect of ER on YELLs' second language writing achievement using an…

The purpose of this study was to determine the amount of time elementary and middle-school students spend away from the classroom and clinic time required to administer vaccines in school-located vaccination (SLV) clinics. We conducted a time study and estimated average time away from class and time to administer vaccine by health department (HD),…
