Cognitive load is a well-known and established theory. Basically, it posits humans have a limited amount of cognitive processing power available at any moment; game theorists would declare our cognitive capacity is a zero-sum quantity. What is used for one purpose is unavailable for other purposes. In classroom, we want to limit extraneous cognitive load Read More

Thinking About Connectionism
For most of human history, communication was an aural or gestural activity. We spoke and we made gestures, other heard and saw our movements. In both cases, the communication was ephemeral. Unheard words and unseen gestures are lost. There is evidence of humans creating painting and other artifacts which presumably were intended for meaningful communication, Read More
Technology Literacy
Technology literacy has been on my mind. My definition is inexact, but I can recognize it in people. You might be able to judge your own technology literacy by reflecting on how you react to new technology. For this post, I am going to ignore those who enthusiastically accept any new device. These folks are goo to Read More
Naming Chunks and Items: Thinking About High-Quality Virtual Classrooms #4
The names given to chunks can contribute to the ease of navigating your online classroom. By giving chunks meaningful and descriptive names, instructors both make it easier to find materials and introduce organizing themes to the course. Consider these names that could be applied to a course in which students are learning to use various Read More
Ease of Use: Thinking About High-Quality Virtual Classrooms #2
Ease of use refers to the effort participants must expand to navigate your course, see and hear the materials, and complete the work you assign. Students are more likely to learn the curriculum if the classroom is easy to use. A related idea, which further supports the importance of easy to use classrooms, is cognitive Read More
Thinking About High-Quality Virtual Classrooms #1
What exactly is a high-quality online course is a question that has held the attention of researchers, practitioners, and entrepreneurs for decades. Many schools have adopted their own set of guidelines, perhaps even templates other methods of making sure instructors have in place what the school leaders believe to be effective practices. Some schools have Read More
Thinking About Digital Reference Tools
Watching some children in my life (from a distance) grow to through into adolescence has led me to think about reference tools in emerging students’ lives. Specifically, I’m thinking about dictionaries, encyclopedias, and maps and I am led to the conclusion that the digital versions we have are better for two of these, but worse Read More
Edtech for Edleaders: Reliable and Robust IT
Is the network reliable and robust? Can all devices stay connected throughout a lesson? Can latency be induced with multiple simultaneous downloads? Are multiple SSID’s seamless? (Can I move around campus and keep my wifi connection?) Is data backed up regularly and reliably?
Leveraging ICT
Computers, networks and digital media are changing the types of tasks educators assign as students access, manipulate, and create information using previously unavailable technologies. Williams (2004) defined fundamental characteristics of tasks which influence how individuals understand the tasks they undertake: the perceived importance of the task; the frequency with which it is done; the time Read More
Technology
Accounting is a technology that accompanied the creation of writing, and counting changed when “we” decided accurate records we needed. Whereas many cultures with primary orality do not differentiate numbers (many unwritten languages quantify using words for “one,” “two,” and “many”). Accounting necessitated accurate calculation of numbers including decimal places. The familiar base 10 and Read More
