The published study of Nurrenbern and Pickering in 1987 raises awareness among chemistry educators that students' success in answering numerical questions does not necessarily reflect their degree of understanding of the related chemical concepts. Efforts have been made to provide more opportunities for students to improve their ability in…

In second language acquisition, a popular method of introducing new vocabulary is by embedding the words in a natural text. Supplementary information (e.g., definitions, illustrations, synonyms, etc.), or glosses, can be included in the margins of the texts to highlight and improve retention of the new words. Previous studies suggest multimodal…

Background and aims: This study was conducted in a clinical setting with the aim of replicating previously used procedures for teaching receptive vocabulary. Researchers increased the number of vocabulary words and maintained use of match-to-sample (MtS), prompting, and reinforcement procedures. Researchers were also interested in the efficacy of…

Students in a typical instrumental analysis course may learn more than 30 analytical techniques. There are more than 150 components associated with the instrumentation that they learn. To help students organize this large amount of information, we classified these components into four categories: sources, samples, discriminators, and detectors. In…

Our ability to shift from current to alternative (e.g., past and future) perspectives (i.e., "self-projection") plays a fundamental role in accurate decision-making. We investigated 3-, 4-, and 5-year-olds' ability to shift perspective to reason about their future and past preferences. In Experiment 1 (N = 96), children were presented…

The purpose of the present study was to investigate the differential effects of video modeling (VM) and picture-based interventions (PI) for teaching children with ASD to recognize emotions in context. The study used an adapted alternating treatments design. One girl and three boys in China, 4.5-5 years old with autism spectrum disorder,…

The most recent studies on the acquisition of evidentiality, be it morphologically or syntactically encoded, have argued that the comprehension lag detected is due to factors having to do with others' authority or mental perspective, where "others" stands for other individuals involved in the experiment in various manners (e.g., the…

This study examines the effectiveness of images on warning signs that communicate risk and risk avoidance in public spaces. Specifically, I compared data from 749 survey responses to determine whether the use of images can increase the effectiveness of a warning sign in a public space. Although the findings indicate that image-based warning signs…

This study explored appropriate speaking activities for speakers of different proficiency levels by measuring the changes in their brain blood flow with near-infrared spectroscopy (NIRS). Fifty adult speakers and learners of English of various proficiency levels participated in the study by undertaking four types of task: a single-speaker picture…

This study examines the relationship between EFL students' noticing and three written feedback strategies. The convenience sampling method was adopted and four intact classes were randomly assigned into four groups: the model, the error correction, the reformulation, and the control groups. After the completion of picture-cued writing tasks as…

Meaningful understanding of chemistry, among others, includes the ability of an individual to think simultaneously at macroscopic, submicroscopic and symbolic levels, and this presupposes the competence to translate between different types of chemical representations. In this study, we investigated 11th grade Greek students' and 3rd year…

This study investigates the impact on L2 oral performance of participatory structure of strategic planning (individual vs. collaborative pair planning) and task complexity (simple vs. complex tasks) defined according to the number of elements involved. It also explores individual and collaborative planners' planning behaviours prior to simple vs.…

This study examines the role of phenotypic stereotypicality on pre-service teachers' perceptions and classroom management decisions about Black girls using participants from the Teacher Education Program (TEP) at the UCLA. Participants read the same subjective disruptive classroom behavior vignette paired with a photo of white or Black girl that…

Student engagement in the second language classroom has been the focus of numerous researchers and teachers. Previous studies have shown that there are several dimensions of student engagement, but it is still unclear how they change (or not) over time and consequently how they affect actual task performance. This study investigated the task…

Most studies of children's attitudes to mathematics have dealt with children in second grade or later, and have suggested that attitudes deteriorate, and anxiety increases with age. The present study investigated attitudes to mathematics in 67 English and 49 Chinese children at the end of their first year of school. The participants were given…
