Suggestions how to improve the U.S. education system

A paradigm shift is needed
The U.S. education system, as many other education system, is still stuck in an industrial age paradigm that does not prepare young people for the knowledge age. There are two basic kinds of change: Piecemeal and systemic (Reigeluth, 1999). Currently, most educational reforms happen in a piecemeal fashion that try to "fix" the existing system. What is needed is a radical systemic reform.

1) The current U.S. education paradigm is based on the "conveyor belt" analogy of the Industrial Age. All students learn the same content in the same amount of time. As Campbell and Monson (1994) state "This may be a model of efficiency, but certainly not for effectiveness". The current paradigm of standardized education allows for valid comparison of students with each other and sort them out efficiently, but does not aim to educate every student (Reigeluth, 1992). When an educational system holds the time of instruction constant, achievement must vary. It is well documented that students learn at different paces. What is the alternative? Instead of grouping students by age group that passes through the education system, schools need to give each learner the time he or she needs to reach the learning goals.

2) Besides the Industrial Age paradigm, the U.S. education system still uses elements from the older Agricultural Age: The three month long summer break was intended to allow children to help during the harvest on farms. Instead of one long summer break, the U.S. could introduce several shorter 2-3 week breaks spread out throughout the year. Research provided strong documentation that the long summer break increases the achievement gap between poor and middle class students (See Summer learning loss and The Case Against Summer Vacation). This also links to the main reason for the education achievement gap in the U.S.: Poverty (or "socio-economic disadvantage") (See Poverty is key factor to improve U.S. education).

3) A dual education system, with an academic and a vocational pathway, offers students valuable alternatives. Unfortunately, the U.S. does not have a well-structured vocational school system as found in many European countries. In Finland, around 50% of students choose vocational school over University education (See The Finland Phenomenon). In the U.S. there exists no alternative to high school, and the current high school curriculum was created to prepare students for higher education not a vocation. In other words, a seventeen year old in the U.S. has only one option: He/She is either a high school student or a dropout (See Americas misplaced disdain for vocational education and Strengthening vocational education could improve U.S. education).

Instead of piecemeal reforms, like "No child left behind" that encourage standardization and assessment (=> sorting), the outdated paradigm itself needs to be changed (See Changing Education Paradigms). Changing the content (educational content standards) or assessment (standardized tests) is not sufficient to meet the needs of the Knowledge Age for the very structure of education discourages self-guided learning, initiative, and creative diversity.

Big Bang Theory Network Diagram

The popular CBS TV-show "The Big Bang Theory" presents a complex network of characters. I created the diagram below to illustrate the various types of relationships.

Celebrities of Science: Making Science Popular

Carl Sagan in Action
Science needs public faces to tell its fascinating stories. A few scientists dared to step into the TV spotlight to make science accessible to a wide audience (and sometimes gain criticism by their peers for simplifying science too much in return).


I compiled a short list of some of the most popular faces of science on TV:


General Science
Physics and Astronomy
Biology


Medicine


History




Wikipedia has an extended list of English-speaking popularizers of science. However, the world needs still more people who can make scientific findings accessible to the public.

The Meta-Geek

With geek culture becoming more mainstream, a novel form of geek emerges - the meta-geek.

A "meta-geek", or "geek geek", is fascinated with geek culture without being deeply involved in any one sub-culture. Meta-geeks are geeks about geek culture itself.

For example:

  • A meta-geek can follow geek-related blogs and watches videos from geek-related events (such as Comic-Con, Dragon-Con, or Star Trek conventions) without going there in person.
  • A meta-geek can be knowledgeable about comic characters without reading comics themselves. 
  • A meta-geek can blog about other geek cultures (for example, see Geek hierarchy chart and Evolution of geek) or read geek-related blogs (for example Geeksaresexy.net or Geekosystem.com).

Academic Workflow of an Education Researcher

As an academic researcher, I use a number of software and hardware tools in concert. To illustrate my academic workflow, I created the diagram below [Click on image to enlarge].


Academic Workflow Diagram

"Input" includes the tools I use to collect and organize documents. I distinguish between different document types and input sources. My two favorite tools to organize documents are DevonThink and PersonalBrain. DevonThink allows organizing documents into a hierarchical folder structure. The in-built AI supports storting out new documents into matching folders. PersonalBrain is a dynamic 3D mindmap that allows annotating and tagging weblinks and documents. I currently have over 8000 weblinks organized in PersonalBrain.

"Output" includes the tools I use to write and publish documents. To write academic publications, I use Scrivener to create an outline of the documents and work on drafts. I enter reference tags from Sente into Scrivener. Once I reach a final draft, I export the text from Scrivener to Word and use Sente to generate a bibliography.

What is learning?

There no single and simple answer to the question "what is learning". This blog post aims to give a short visual overview over major theories of learning: Behaviorism, Cognitivsm, Constructivism (classic and socio-cultural), and Networked learning/ Connectivism.

"Learning" is defined differently by different research fields and frameworks. The illustrations below are my attempt to visualize the progression of major theories of learning:

Learning is often closely connected to the nature of knowledge (Epistemology). Like learning, knowledge can be defined in many different ways. In relation to knowledge, Paavola (2005) distinguishes two types of learning. Based on Paavola's paper, I created the following table:





I created the dynamic mindmap below to provide an overview over some major theories of learning and education concepts. This mindmap is ongoing work in progress. Your feedback and suggestions are welcome.

To navigate the dynamic mindmap below, just click on a term and it will move to the center - showing related concepts. You can also search for terms in the textbox at the bottom.
