The purpose of this study is to describe students' ability in solving mathematical representation problems evaluated from mathematical disposition. The subjects are three students of 10th grade of public senior high school (PSHS) in Padalarang, West Java, Indonesia. They were selected from 35 students with high, medium, and low mathematical…

Using visuals is a well-known strategy to teach emergent bilinguals (EBs). This study examined how preservice teachers (PSTs) implemented visuals to help EBs understand mathematical problems and how an innovative intervention cultivated PSTs' capability of using visuals for EBs. Four middle school mathematics PSTs were engaged in a field…

In this study, we extend previous work on instructors' use of technology by examining how students' perceptions of teacher credibility and affective experience differ depending on how frequently instructors use two common forms of instructional technology: PowerPoint, which is typically used "inside" the classroom; and email, which is…

To deepen our understanding of those aspects of problems that cause the most difficulty for solvers, this study integrated eye-tracking with handwriting devices to investigate problem solvers' online processes while solving geometry problems. We are interested in whether the difference between successful and unsuccessful solvers can be identified…

The aim of our research was analysing the animated interactive multimedia learning activities (IMLA) with a Geography/Sciences contents, within the Mathematics and Environmental Exploration digital textbooks for the 2nd grade, edited by the CD PRESS Publishing House in 2014. We conceived an assessment grid focusing a series of features of the…

The purpose of this study was to explore the effects of multi modal representations within writing to learn activities on students' critical thinking. Mixed method was used. The participants included 32 students 5th grade from elementary school. The groups were randomly selected as a control group and the other class was selected as the…

Relating mathematical concepts to graphical representations is a challenging task for students. In this paper, we introduce two visual strategies to qualitatively interpret the divergence of graphical vector field representations. One strategy is based on the graphical interpretation of partial derivatives, while the other is based on the flux…

Organic chemistry students struggle with understanding the energetics of chemical reactions. Reaction coordinate diagrams are one tool that is widely used in organic chemistry classrooms to assist students with visualizing and explaining the energy changes that take place throughout a reaction. Thirty-six students enrolled in organic chemistry II…

Previous studies have found that individuals with autism spectrum disorders show impairments in mentalizing processes and aberrant brain activity compared with typically developing participants. However, the findings are mainly from male participants and the aberrant effects in autism spectrum disorder females and sex differences are still…

The purpose of the present meta-analysis is to the investigate the overall effectiveness of L2 vocabulary instruction and to find the moderator variables affecting its effectiveness. By defining a rigorous inclusion and exclusion criteria, a total number of 16 primary studies (N = 1008), 7 published and 9 Ph.D. dissertations, were included. Under…

This study analyzes the impact of signaling principles upon the effective use of interactive learning media. Normally, designers just design and develop learning media for use in schools without considering the way it eases users' tasks. Bearing in mind that signaling users while they are learning through interactive learning media is important,…

Students with disabilities are reading at levels lower than their nondisabled peers. Some school districts have incorporated Professional Learning Communities (PLCs) to assist in closing the reading achievement gap between students with disabilities and students without disabilities. There is a gap in the literature regarding which PLC-implemented…

Developing students' geometric reasoning skills is dependent on the quality of task designs and the role of the teacher. The purpose of this study was to apply Sfard's (2008) interpretive framework to analyse changes in students' mathematical discourse. This paper reports on the results of an investigation into the ways one class of Year 7…

Learning Mathematics in Primary Schools is often mediated through the use of multiple representations. However, teachers may not pay enough attention to the way they use these representations. Given that the translations among representations may not always be smooth, it may be insightful to examine how teachers mediate learning through the use of…

This study aims to find out the student responses in enhancing new vocabulary through subtitled English Movies. And the research question is what are students' responses in enhancing new vocabulary through subtitled English movies? To achieve this objective, the study employed a quantitative method. The data were obtained from the questionnaire.…
