A program is described and presented to readily plot the molecular orbitals from a Huckel calculation. The main features of the program and the scope of its applicability are discussed through some example organic molecules. (Contains 2 figures.)

Science on a Sphere (SoS) is a compelling educational display installed at numerous museums and planetariums around the world; essentially the SoS display is a large spherical surface on which multicolor high-resolution depictions of (e.g.) planetary weather maps may be depicted. Fascinating as the SoS display is, however, it is in practice…

While engaged in a research project involving the use of visual methods with children, the authors discovered that there are many ethical considerations beyond what could have been predicted at the outset. Some of these considerations are important with respect to research with children in general, while others arise more particularly when using…

This study determined whether using photographic stimuli displaying different ethnicity (African American vs. Caucasian American) influenced preference, word count, and number of content units produced by African American or Caucasian American participants. Six photograph pairs depicting common scenes were developed, differing only by model…

We are in the age of the millennial student: students are ethnically diverse, sheltered, pressured, confident, technologically advanced, team oriented, and some have helicopter parents. Furthermore, while academically inclined, these students also show increases in pressure, feeling overwhelmed, and levels of stress, in addition to academic…

The concept of formative assessment is considered by many to play an important role in enhancing teaching in higher engineering education. In this paper, the concept of the flipped classroom as part of a blended learning curriculum is highlighted as an ideal medium through which formative assessment practices arise. Whilst the advantages of…

Beginning learners of English frequently use flashcards as a tool for learning vocabulary. However, because of the consciousness difference between the picture-readers and picture-drawers on vocabularies, errors may be involved in the learners' comprehension of the vocabulary terms on the flashcards. This article develops and evaluates an English…

Children with disabilities often demonstrate difficulties in code-focused and meaning-focused domains of literacy. Best practice indicates that skills within these domains should be taught together. The current study used principles of ABAB single-case experimental design to monitor the development of narrative retelling and phonemic awareness in…

The findings of the research literature about the necessity and contribution of Interactive Whiteboards (IWB) are not unequivocal and are sometimes contradictory. The study aimed to examine the interactive attributes in lessons with an IWB and the students' attitudes. Methodical structured observations of 26 science lessons were conducted in…

This article describes the design and application of a computer-based system for simultaneously teaching Korean, English and Japanese languages in a classroom setting using knowledge visualization techniques to show the relationships between vocabularies, grammars and meanings. The system consists of a knowledge database of Korean, English, and…

Mathematical problem solving typically involves manipulating visual symbols (e.g., equations), and prior research suggests that those symbols serve as diagrammatic representations (e.g., Landy & Goldstone, 2010). The present work examines the ways that instructional design of student engagement with these diagrammatic representations may…

In this paper, we discuss how externalizing learners' interaction behavior may support learners' explorations in an adaptive educational hypermedia environment that provides activity-oriented content. In particular, we propose a model for producing interpretative views of learners' interaction behavior and we further apply this model to…

Field trips are recognized as an essential component of the study of geography. They are popular with learners and teachers, but their value as learning experiences is largely assumed. What is needed are interactive and relevant learning activities like "drawing in the sand," a participatory learning activity that has been introduced…

The rationales behind design are dissimilar to those behind art. Establishing an adequate theoretical foundation for conducting design education can facilitate scientising design methods. Thus, from the perspectives of the semiotic theories proposed by Saussure and Peirce, we investigated graphic design curricula by performing teaching…

PowerPoint has received much criticism regarding excessive use of text and the lack of contact with the audience. Why presenters use PowerPoint in this way has not been studied so far. Our study using interviews with beginning and advanced presenters shows that some use the program as a speaking note and as a means to draw the attention away from…
