Educational Impact: Cell Phones


























I made the decision to analyze the educational impact over technical attributes of mobile phone technology. This choice stems from my lack of knowledge and experience regarding cell phones in the educational environment. Using McLuhan’s model, examination of the progressions of cell phone technology reveals explicit implications for adoption.

Cell phones significantly enhance the educational environment through a variety of instructional methods. To begin, cell phones expand the use of mobile learning including distance education and collaborative projects. Additionally, this technology improves data collection for homework, opinion polls, grading quizzes, class discussions, and research projects (Elise, 2008). Another enhancement created by cell phones involves assistive technology. Elise (2008) reports that mobile devices support visual and hearing impairments by offering free online resources and multiple applications for communication such as text and voice. Using cell phones in the educational environment improves communication and collaboration as students actively engage with peers, teachers, and experts to authenticate content. Finally, this technology advances classroom management as students and teachers store video and images, use word processing for notes, save lectures as podcasts, and read online books and articles (Elise, 2008).

The numerous enhancements provided by cell phones leads to discussion on what this technology obsoletes. Currently, budget cut-backs hinder technology development. However, funding for cell phones is the parent’s responsibility. Therefore, schools can integrate educational technology strategies without the burden of purchasing additional computers or mobile devices (Roberson & Hagevik, 2008). Furthermore, the traditional classroom transforms to learner-centered by eliminating the negative opinion that cell phones only promote social behavior. Elise (2008) suggests that future educators will appreciate the technology as a learning tool rather than a social toy.

The theory underlying cell phones in education has roots in the principles of Comenius’ instructional method. His theory supports customized education, integration of subjects, and developmentally appropriate design (Saettler, 2004). Comenius believed that a teacher could educate a mass amount of students by managing the classroom environment with a lesson introduction followed by individual learning segments and collaboration with peers. Before his time, Comenius suggested theory related to distant learning. Like Comenius, classroom strategies associated with cell phones encourage authentic learning experiences, flexible teaching, and learner ingenuity (Prensky, 2005).

Another factor related to retrieval involves global competition. The Space Age spawned urgency for mass education. Mobile technology has significantly impacted the effect on global communication and collaboration. With this technology impacting the educational system, global consciousness redevelops as fierce competition requires innovative and connected graduates (Elise, 2008).


What is the future of cell phones in education? Mobile technology will continue to improve global communication and personalization of digital devices (MOCOM2020, 2010). Additionally, MOCOM2020 (2010) reports over 4 billion mobile phone users. These facts lead to the belief that educational barriers will diminish as students develop into digital natives, compelling institutions to change traditional practices to digital methods. Eventually, educational technology theory will thrive as acceptance of mobile technology reaches critical mass.

Emerging Technolgy: The Pocket Projector

In 2008, several companies launched the first pocket projectors. This handheld, portable device enables users to cast multiple applications including video and images onto a screen equipped to 50 inches. Pocket projectors connect to a variety of media devices including the iPod, computer, digital camera, and cell phone (Feierman, 2010). At $300 for high-quality, this cost-efficient mobile device creates another element to a collaborative, interactive teaching environment.

The major challenges of this technology include improving battery life, brightness, and resolution. Currently, pocket projector developers are making advancements to improve these issues in newer models. Currently, the average battery life ranges from 30 minutes to 2 hours. By 2012, Colegrove (2010) predicts the battery life will extend to 4 hours. The brightness and resolution pales in comparison to the detail of larger digital projectors. However, the demand for this technology is increasing causing significant advances. Colegrove (2010) reports up to 50% better resolution since the first models.

Pocket projectors are designed to be used anywhere. Because the device travels easily, it offers multiple solutions for classroom, business, and entertainment demonstrations. The small size is an noticeable advantage. However, pocket projectors are also eco-friendly, lightweight, compatible with multiple devices, battery-operated, and feature an extended lamp life (Jennifer, 2009). In the classroom, pocket projects offer a simple solution to displaying images, video, and text (Mosotech, 2010). The unlimited learning opportunities will craft lessons that will spark discovery and invoke a spirit of collaboration.

Once sound and visual quality improve, pocket projectors will improve communication in the classroom. The demand for this emerging technology reveals that it is well on its way to becoming emerged. A remote would make this technology even better. Accessing the files from an separate location would add an additional “Wow” factor.

View the following video for a demonstration.
