This study aimed to examine the diagrammatic representation skills and problem-solving performances of students according to their problem-solving representations. A cross-sectional survey design using quantitative methods was used in this study. The sample consisted of 31 second-grade and 41 third-grade students from a public primary school in…

Different molecular representations are usually used to depict the three-dimensional (3D) structure of organic compounds. Mastering the skill of interconverting one form into another is essential for students to ensure success in organic chemistry. The traditional and recently developed methods for completing such interconversions that rely on 3D…

Structural equation modeling (SEM) is widely used in behavioral, social, and education research. Drawing publication-ready path diagrams for SEM is not a pleasant task with the existing software. The article introduces an open-source web-based graphical application, "semdiag," for drawing WYSIWYG SEM path diagrams interactively. The…

Flashcards are with us from our very earliest learning experiences. As infants, we learn to speak words from flashcard pictures. As toddlers, we are introduced to vocabulary concepts and thinking skills with flashcards. In early learning experiences we learn facts, languages, associations, and even social skills. Flashcards remain highly prevalent…

In this article, we study the role of teacher support in a collaborative learning setting that involves students' constructions of visual representations in the environmental education context. Despite the consensus in the field of science education research that engagement with visual representations--such as diagrams, animations, and graphs--can…

In both general chemistry and analytical chemistry courses, students are introduced to the concept of predominant species in solution when discussing acid/base chemistry. Speciation diagrams are often used to illustrate the concept and predict the relative abundance of species in solution. Herein, we describe a laboratory experiment for an…

This study compared effects of student choice of task sequence to two variations in teacher-manipulated task sequences on on-task behavior of elementary-aged students with disabilities. Researchers modified Call et al.'s (J Appl Behav Anal 42: 723-728, 2009) demand assessment to determine high-, moderate-, and low-probability tasks. Next,…

The teaching-learning process is complex and requires continuous research and dedication. Research has been important to prove that student achievement can improve when active methodologies are properly implemented, either in isolation or integrated with a short lecture. The purpose of this work was to evaluate the performance and perception of…

This paper investigated two adult English learners' reading processes of reading informational texts through Retrospective Eye Movement Miscue Analysis (REMMA). The readers read two texts and retold what they read. Their reading was recorded by the Tobii Pro eye tracker. They watched their eye movement video and discussed their miscues and eye…

To prepare for college and careers, students at all grade levels can begin identifying the course for their futures. By incorporating purposeful activities, teachers can give students opportunities to visualize and state their future goals.

Eye tracking is a useful tool for studying human cognition, both in the laboratory and in real-world applications. However, there are cases in which eye tracking is not possible, such as in high-security environments where recording devices cannot be introduced. After facing this challenge in our own work, we sought to test the effectiveness of…

Reaction coordinate diagrams (RCDs) are an important tool used to visualize the energetics of a chemical reaction. RCDs provide information about the kinetics of the reaction, the mechanism by which the reaction occurs, and the relative thermodynamic stability of the molecules in a reaction. Previous research studies have characterized student…

Textbooks on Dynamical Systems Theory usually present only three types of codimension-one bifurcations occurring in autonomous first-order nonlinear differential equations. These three types are called saddle-node, transcritical, and pitchfork. However, the number of bifurcations is virtually infinite. In this didactic work, the bifurcation…

Most individuals view the world through images and many share memories through social networking sites (SNSs) and other online spaces continuously. Due to the immense amount of communication through images, it is increasingly important to develop competencies in visual, media, and privacy literacy; therefore, this article presents Photovoice 2.0,…

iPhoneography is the practice of capturing, enhancing, and sharing images using a smartphone device. With the emergence of image-based social media platforms that highlight the experience of making images, it becomes critical to examine how the act of creating images enhances comprehension of visuals. The practice of iPhoneography and image-based…
