Shepard Fairey's famous poster of Barack Obama with the word "HOPE" surely contributed to Obama's public persona. In this article, the author presents a lesson inspired by the contemporary relevance of the poster. In this lesson, students will learn that photographs can be altered to create a work of art and that art can be used to create a…

The Wilcoxon statistics are usually taught as nonparametric alternatives for the 1- and 2-sample Student-"t" statistics in situations where the data appear to arise from non-normal distributions, or where sample sizes are so small that we cannot check whether they do. In the past, critical values, based on exact tail areas, were…

We propose a robust framework for clustering data. In practice, data obtained from real measurement devices can be incomplete, corrupted by gross errors, or not correspond to any assumed model. We show that, by properly harnessing the intrinsic low-dimensional structure of the data, these kinds of practical problems can be dealt with in a uniform…

The goal of this action research is to increase student awareness of context clues, with an emphasis on student use of visual cues in making predictions. Visual cues in the classroom were used to differentiate according to the needs of student demographics (Herrera, Perez, & Escamilla, 2010). The purpose of this intervention was to improve…

This monograph offers an overview of the current research work carried out in Croatia and the surrounding countries, and specifically an interesting insight in teaching and learning issues in these countries. The authors discuss the need of the general population for becoming good problem-solvers in society of today, which is characterised by…

Of the eight practices of science identified in "A Framework for K-12 Science Education" (NRC 2012), helping students develop and use models has been identified by many as an anchor (Schwarz and Passmore 2012; Windschitl 2012). In instruction, disciplinary core ideas, crosscutting concepts, and scientific practices can be meaningfully…

Since literacy is essential for learning, one of the main purposes of elementary school is to enhance students' literacy skills. In many countries, it's quite common to use an interactive whiteboard in class, and Taiwan is no exception. The purpose of this study was to determine the effectiveness of using an interactive whiteboard to teach picture…

Physics teachers use experimental devices to show students how scientific concepts, principles, and laws are applied to understand the real world. This paper studies question generation of secondary and under-graduate university students when they are confronted with experimental devices in different but usual teaching situations: reading about…

Test-preparation classes that focus on skills will benefit students beyond the test by developing skills they can use at university. This article discusses the purposes of various tests and outlines how to design effective test-prep classes. Several practical activities are included, and an appendix provides information on common standardized…

One of the challenges that social studies educators face daily is how to make student learning relevant. Digital technologies can play an important role by connecting what happens in the classroom to the world beyond. One way to do this is by turning students into producers of information and having them create content rather than simply consume.…

Students are frequently presented with novel visualizations introducing scientific concepts and processes normally unobservable to the naked eye. Despite being unfamiliar, students are expected to understand and employ the visualizations to solve problems. Domain experts exhibit more competency than novices when using complex visualizations, but…

In this paper, it is advocated that the feedback loop between learners and teachers could be improved by making use of augmented reality (AR) techniques. The bidirectional communication between teacher and learners is sometimes hampered by students' fear of showing themselves up in front of their classmates. In order to overcome this problem, a…

Many students with complex disabilities (e.g., moderate and severe disabilities, autism spectrum disorder) require explicit instruction in social skills in order to respond to and initiate interaction with their peers. This article reviews the research on developing social skills groups to teach peer interactions for students with complex special…

The integration of information and communication technology into early year's classrooms is increasingly important for engaging and motivating digital learners. One of the more promising recent revolutions in educational technology that encourages learner's involvement is interactive whiteboard (IWB). Many schools have accepted IWB as core…

The problem addressed in this study was to understand how preservice teachers documented and communicated learning via working eportfolios to demonstrate reflective practice in a teacher education class. The purpose of the study was to use mixed methods to understand how preservice teachers document and communicate their learning in working…
