Workshop Goals

1. Become familiar with PhET simulations to teaching critical thinking • What makes PhET sims unique learning tools? • How can they be used in class? (

easy, effective)

2. Plan for sim use in your class • Identify useful PhET sims • Practice activities using sims • Develop your own activity

Pendahuluan

• Peranan Lab dalam Pembelajaran Sains • Lab Maya (Virtual Lab) dalam pembelajaran Sains • Keterampilan Berpikir kritis dalam pembelajaran sains

Berpikir Kritis (Critical Thinking)

• Ennis (1985), berpikir kritis merupakan bagian dari pola berpikir tingkat tinggi yang bersifat konvergen. Berpikir kritis menggunakan dasar proses berpikir untuk menganalisi argumen dan memunculkan gagasan terhadap tiap-tiap makna dan interpretasi, untuk mengembangkan pola penalaran yang kohesif dan logis, memahami asumsi dan bias yang mendasari tiap-tiap posisi, serta memberikan model presentasi yang dapat dipercaya, ringkas dan meyakinkan.

• Facione (1998), inti berpikir kritis adalah deskripsi yang rinci dari sejumlah karakteristik yang berhubungan, yang meliputi analisis, inferensi, eksplanasi, evaluasi, pengaturan diri, dan interpretasi

Indikator Keterampilan Berpikir Kritis ( R. Ennis, 1985)

CCK in middle school:

“Make the light bulb light”

CCK in high school:

“Explain why the light dims when you turn the heater on”

Thoughts on these tools …

Designed to support inquiry learning

Use accurate, dynamic visual representations Create a game-like environment Show the invisible Make simulations highly interactive Provide real-time, animated feedback as students play Implicitly scaffold inquiry through design of controls and representations Allow actions that would be difficult or impossible in the real world Provide an intuitive interface, usable without instructions

Use of PhET sims in class

Lecture/classroom Visual Aid, Demo complement, Interactive Lecture Demos, & Concept tests Lab and Recitation Group activity, Exploration & discovery Homework Pre-class assignment – introduce new ideas Post instruction – develop robust understanding

Ideas for Next steps

Try ideas from teachers

• http://phet.colorado.edu/en/for-teachers/browse-activities • Use Key Word Search to find a sim, then scroll down for ideas • Watch for Gold Star Inquiry Activities • • • •

Think about your learning goals

use Key Word search to find sims

Search for sims by Topic or Grade level Read handouts from webinar Watch iTunes PhET videos

Sample lesson ideas

These following supplemental slides have examples of ways to use PhET that could be used.

Simulation Extends Lab Concepts

?

Qualitative lab

: Use the motion probe to graph position and velocity of some motion, also make motions to fit given graphs •

Quantitative lab:

Use Moving man to accurately interpret and draw position, velocity and acceleration graphs for common situations and explain reasoning.

Demo Scientific Model

Electrostatics – Traditional balloon demos - Charge transfer, Coulomb attraction, Polarization

Simple, but effective

Replace Expensive Equipment

Challenge: Use the simulation to see how the design of a lens effects how it works.
