During the August 21, 2017, solar eclipse, high school students measured secondary cosmic ray flux using QuarkNet detectors. These students conducted experiments examining cosmic ray flux, shower, speed of muons, and muon lifetime using QuarkNet cosmic ray muon detectors (CRMDs). These detectors measure muon flux of momenta greater than ~2 GeV, a…

The falling temperature of the photosphere with height is responsible for the effect known as limb darkening. The Sun is not equally bright all over the disc. When we observe the Sun towards the limbs, it appears to get darker. Light from the photosphere travels through an absorptive medium. Therefore, one can see only so far into the photosphere.…

This quantitative study investigates the impact of four types of discussion activities on adult learners' asynchronous online interactions. Specifically, this study aims to understand how different discussion activities incorporated into online discussion boards motivate adult learners' online participation. The four discussion activities are…

Little is known about the impact of teachers' questions on child bilingual's heritage language reading process and outcomes. This study examined the role of adults' questions in English-Mandarin bilingual preschoolers' Mandarin word learning, story comprehension, and reading engagement. Ninety-nine 4- to 5-year-old preschoolers in Singapore were…

To determine the effects of explicit instruction (EI) and potential moderators in second/foreign language (L2) teaching, this study meta-analyzed 28 primary reports (a total of 67 unique samples, N = 3754). The main results show that EI was significantly effective in facilitating L2 development, with effect sizes ranging from moderate to large…

Background: Integrating programming in K-12 curriculum has become a global consensus. Teachers are central figures in programming instruction. But the majority of current research focuses on teachers' external teaching behaviours and less on teachers' attitudes towards programming. Objectives: The purpose of this study is to validate the K-12…

Differentiated Instruction (DI) is a hot topic in educational research. Keeping abreast of its latest developments and frontiers can provide new perspectives for future study. Using CiteSpace software, 1086 publications included in the Web of Science core collection from 2000 to 2020 were analysed to create knowledge maps of DI research. The…

From my home on the west bank of the Columbia River in Richland, Washington (46.3°N latitude), I have an unobstructed view of the sunrise along the east bank during an entire year. As a retirement project after a career of teaching and research in physics, I decided to take photographs of the sunrise for a year and, and at the same time, carry out…

The Sun is a central feature to the human experience. It is found in many familiar idioms like "nothing new under the Sun." It defines our days, makes our planet habitable, and is the ultimate origin of your last meal. Yet how do we understand how it works?

Since the end of the last century, the English as a foreign language (EFL) community seems to have entered a new era: the postmethod era. Despite fierce debate about its rationality and feasibility, the three pedagogical parameters--particularity, practicality, and possibility--have been influential and applied to various teaching contexts. Under…

This study offers a critical content analysis of thirty-six contemporary realistic picturebooks featuring transracial Chinese adoption. The theoretical framework of critical literacy highlights significant sociocultural implications of these portrayals: in particular, negative stereotypes and ideologies, in an attempt to call for inclusivity and…

Numerous studies have tested the effects of extensive reading (ER) on L2 acquisition, while limited research has investigated the implementation of ER, especially in secondary L2 teaching contexts. In line with the advocacy of integrating ER into L2 curriculum, this qualitative case study explores a veteran EFL teacher's perceptions of ER…

Situated in China and under the context of curriculum reform, this project is an effort to combine long-time separate research streams in language teaching and learning studies: the history-in-person perspective (Holland & Lave, 2001) and the discourse analysis perspective (Cazden, 1988). Informed by the concepts of…

At a conference on educational physics, someone described a series of multiple-choice problems to test students' ideas about various mechanical phenomena. One of the problems questioned students' conceptions about the shape of the Earth's orbit in the solar system. The question was as follows: "Which of the following schematic illustrations…

In this study, we propose to analyse students' drawings using the Semiotic Cultural Psychological Theory (SCPT), a socio-cultural psychological model that integrates semiotics with dynamic systems theory. According to the SCPT framework, students-generated drawings can be analysed in terms of generalised meanings, i.e., implicit assumptions about…
