eReader usage leads to less recall than paper books

eBook reading

As study conducted at Stavanger University (Norway) reported that "readers using a Kindle were significantly worse than paperback readers at recalling when events occurred in a mystery story.

In the study, 50 readers were given the same short story. Half read the 28-page story on a Kindle, and half as paperback. Afterwards, participants were tested on aspects of the story including objects, characters and settings.

The researchers found that "The Kindle readers performed significantly worse on the plot reconstruction measure, for example, when they were asked to place 14 events in the correct order."

As an explanation, the authors refer to the tactile properties of paperbacks. "When you read on paper you can sense with your fingers a pile of pages on the left growing, and shrinking on the right. The differences for Kindle readers] might have something to do with the fact that the fixity of a text on paper, and this very gradual unfolding of paper as you progress through a story, is some kind of sensory offload, supporting the visual sense of progress when you're reading."

The authors suggest that publishers should make evidence-based decisions about what kind of content is best presented in what kind of format.

Great movies for science geeks and science teachers

Mad Scientist
(Source: http://content.science20.com/)
Many movies portrait scientists (see a list here), but only few try to give realistic depiction of science and scientists (sometimes in a historical context). Scientists are often either portrayed as mad loners (see image above) or a wizard-technicians (e.g. forensic scientists or computer hackers in almost every crime TV show).

Here is a short list of movies that do a better job at representing science (and show the scientist as a positive hero):


Name of the movie
Focus
Longitude (2000)
Technology: A clockmaker needs to collect convincing evidence to support the reliability of his method to measure the position of ships out in the ocean.
Astronomy. An astronomer strives to collect convincing evidence that the royal calendar is inaccurate.
Scientists run experiments to explore an alien virus.
Architecture. The challenges of building a Japanese castle.
Agora (2009)
Astronomy. Conflict between religion and science.

What is vocational education? What are current challenges of VET in Switzerland?

Vocational Education in different contexts
(Source: technicaleducationmatters.org)
Vocational education (also called  career and technical education (CTE), technical and vocational education and training (TVET), or vocational education and training (VET)), can be described as education that prepares people for a specific trade, craft, or career.

Traditionally, vocational education refers to classic trades such as carpenter, mason, plumber, electrician, blacksmith, etc. However, the lines can get blurred when one includes programs such as engineering, accountancy, nursing, medicine, architecture, pharmacy, and law.

At the upper-secondary level in Switzerland, over 60-70% of young people enter a VET program while 30-40% go to university (OECD report). Given the above definition of VET, many university students could also be considered part of VET (such as engineers, medical doctors, architects, lawyers, psychologists, teachers, etc.).

Following this line of thought, education could (roughly) be divided into two strands:
  • Occupation-specific education: Education programs that prepare students for a specific profession (which often includes practical experiences through internships and apprenticeships).
  • General education: Education programs that teach knowledge and skills independent of specific careers, particularly the liberal arts (for example literature, languages, art history, music history, philosophy, history).
Graduates from occupation-specific programs find it often easier to find a job after their program as they have a clear(er) career path, practical experience on the job, and relevant skills. However, university education is still perceived as more desirable. In 2014, over 13,000 Swiss VET apprenticeship positions could not be filled (Newspaper article July 16 2014). In the UK, studio schools try to combine schools with VET. In the US, forming a vocational education system could improve the overall education system (see article here).

Like Germany and Austria, Switzerland has a long history for vocational education going back to apprenticeship programs in the middle ages. Today, Switzerland builds on the 'dual system' approach for VET. Students learn practical skills and procedural knowledge at the workplace (under the supervision of a vocational trainer) 3-4 days/week) and theoretical (declarative) knowledge in vocational school (under the supervision of vocational teachers) (1-2 days/week). Additionally, students also attend yearly inter-company courses (organized by their professional unions) in industry training centers to complement their skill sets (under the supervision of vocational instructors). Some professions, particularly commercial employees, attend vocational school full time. Swiss VET program can take between two and four years and lead to a Federal VET Diploma (full 3- or 4-year program) or a Federal VET Certificate (less demanding 2-year VET program). Graduates from a university of applied sciences receive a 'professional bachelor' or a 'professional master' (Newspaper article June 18 2014). Currently, PhDs can only be granted by the regular universities.

Switzerland draws a distinction between vocational education and training (VET) programs (which take place at the upper-secondary level) and professional education and training (PET) programs (which take place at tertiary level). Beyond PET, universities of applied sciences (Fachhochschulen) offer vocational education at higher tertiary levels. Pathways enable people to shift from one part of the education system to another. The line between PET and university education (particularly of the occupation-specific programs) becomes increasingly blurred.

A big difference between the two strands is the cost factor. While the state heavily subsidizes university education (students only pay about $700/ semester), higher degrees in professional education need to paid fully by the student (often around $3000-4000/ semester). A professional diploma can cost as much as $30,000 to 40,000.

The question for a society (and economy) is to find the right balance between the two education strands. A society that focuses solely on occupation-specific education might have a highly skilled workforce but lack people who see pattern across narrow contexts, think critically about bigger issues, and find innovative out-of-the-box problem solving approaches.

Gender stereotypes and the lack of women in STEM careers

Role models and encouragement can make a big difference when it comes to education program and career choices. Currently, less than 25% of STEM (Science, Technology, Engineering, and Math) in the US are held by women.

Recent research (*) suggests that boys and girls have similar psychological traits and cognitive abilities, thus gender is not the determining factor for careers in STEM.

One contributor could be repeated (but often concealed) encouragements that reinforce gender stereotypes (see video below). Women need more role models, opportunities to experience, and encouragement towards careers in STEM.

Spatial storytelling using tablets and Oculus rift

Interactive spatial storytelling with iDNA app
[Picture by Apelab]
Swiss startup company Apelab focuses on innovative ways of using digital media for storytelling. One particularly interesting project is iDNA.

Using an tablet or Oculus Rift, the user sees an interactive animation movie. The user can explore 360 degrees of each scene by moving the device around. Depending on which element in the scene the user focuses on, the story seamlessly takes a different path. The viewer gets the illusion of being right in the middle of each scene.



The paper book might be on the decline, but storytelling will find interesting new ways.

KidZania is a Mexican owned company who runs a series of vocation-based theme parks around the world.

Each KidZania location features an indoor scaled-down (2/3 of full size) model city in which children can experience different professions through role-play (following the instructions of animators). Around 60 different establishments (including a hospital, fire station, beauty salon, bank, radio station, supermarket, television station, pizzeria, and theater) offer nearly 100 different role-playing activities.

To simulate the real world, KizdZania teaches capitalist-consumerist values of earning and spending money. The role-play gets rewarded with KidZania's own currency, kidZos, which can be spent within KidZania for goods and services provided by other children working in that profession.

Each Kidzania role-play activity is heavily and directly sponsored by multi-national or local brands (what they call "integrated marketing partnership"). For example, aviation professions are sponsored by American Airlines, bank professions are sponsored by HSBC, hospitality professions are sponsored by Coca Cola, Domino's pizza, Nestle, Kellogg's and Danone, Engineering professions are sponsored by Mitsubishi Motors and Honda, and so on.



Currently, the Kidzania franchise has locations in Mexico City, Monterrey (Mexico), Tokyo, Jakarta, Osaka, Lisbon, Dubai, Seoul, Kuala Lumpur, Santiago, Bangkok, Kuwait, Mumbai, Cairo, and Istanbul (with several new locations in planning).
