Redesign of Black Sand Exhibit at Exploratorium Museum ED 229 Huiping Liao Wuping Lu
Introduction n n Museum: Exploratorium Location: San Francisco, CA Time: from 3: 10 to 4: 30 PM, Oct 21 Exhibit: Black Sand
Black Sand - Manipulation n n Magnetic lines of force can be seen and felt Form images of the magnetic field Provides a very pleasant and unusual tactile sensation Magnetic "castles of sand" can also be built
Black Sand - Learning Intended n n Electromagnetic Forces Ferromagnetism Magnetization Perception of Texture

Observation n n n 3: 10 Dad and son: 2 minutes (guided by father). 3: 15 Parents with two sons: around 7 minutes 3: 23 Mom with two boys and one girl: around 6 minutes 3: 30 Two Ladies with shopping bags: 3 minutes. 3: 34 Parents with the son: 8 minutes 3: 44 Four Adults (half and half in gender); 3 minutes n n 3: 47 Parents with their daughter: 3: 58 Mom with daughter: mom with glasses on. Mom play the black Sand with the daughter happily. She build a bridge between the two magnets with her daughter. Then they add more sand on the bridge and shake the bridge a little bit to have pure sand away from the iron sand. Mom keeps talk to her daughter and they seem enjoy playing sand together.
Interview n n n Ping: Do you enjoy it? Rebecca: yes P: why? R: it’s not at school. P: Do you come here with your parents? R: My mum P: where is your mum? R: She went to get a cup of drink. P: Do you know what is it? R: ( read the explanation on the board) yes, its black sand from iron ore, you can find it on the ocean beach. P: Any more? R: No.
Summary on Observation and Interview n n n Most of then do not pay much attention on the text explanation; Read through only when bored but have to stay there; If with only button to control, no fun, got to touch and play with it for a while Moms are not attracted that much No challenge and curiosity (Food for thought thereafter)
Evaluation n Strength • • • Manipulative Mapping Tangible n Weakness • Playing more than learning • Lacking strong motivation for real learning • Lacking interactivity • Not very safe • Not clean • No individualized
Principled Redesign n n Purpose: elicit real learning Learning Theories Employed • Primarily based on Contextual Model of Learning (Falk and Dierking) Personal Context n Sociocultural Context n Physical Context n • Also integrate other learning approaches if appropriate (may overlap)
Principled Redesign – How to Improve n Set up a computer terminal (Learning Station) along Black Sand (Play Station) with following features • Learning modules in different areas on various levels – opportunities for choice based on personal experience (personal context of CML, cognitive) • Learning material represented by multimedia (cognitive, media response) • Assessment after each modules – reinforce learning • Searching and FAQs – interactivity, choice and control (personal context of CML)
Principled Redesign – How to Improve • Offer rewards n Motivation by means of coupons to buy relevant books, discounted admission tickets for next visit, or black sand toys based on the result of assessment (personal context of CML, behavioral, motivation) • Extend learning beyond museum n Coupons and tickets with key learning elements on the other side and toys of black sand – reinforce events and experiences out -side the museum (physical context of CML)
Principled Redesign – How to Improve n Improve Environment • Use special floor material preventing sliding – safety (physical context of CML) • Set up a sink for visitors to wash hands – cleanliness and attract more females (physical context of CML) • Use relevant pictures on the wall behind Black Sand (cognitive)
Current Learning Environment
Redesigned Learning Environment with Learning Station and Sink Added, Background Pictures Replaced, and Floor Modified
