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

Workshop Goals

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)

• What are PhET simulations and who creates them?

• How can PhET simulations help students learn?

• Explore the simulations and activities• Discuss how to find ideas for use

Make easy to use

CCK in middle school: “Make the light bulb light”

CCK in high school:

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

Adaptable for Variety of Learners

Compare these tools? Thoughts on these tools …

Provide real-time, animated

feedback as students play

Implicitly scaffold inquiry through

design of controls and representations

Make simulations highly interactive

Use accurate, dynamic visual representations

Show the invisible

Provide an intuitive interface,

usable without instructions

Create a game-like environment

Allow actions that would be difficult or impossible

in the real world

Designed to support inquiry learning

Use of PhET sims in class

Lecture/classroomVisual Aid, Demo complement, Interactive Lecture Demos, & Concept tests

Lab and RecitationGroup activity, Exploration &

discoveryHomework

Pre-class assignment – introduce new ideasPost 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.

Lecture – Interactive Lecture Demos

Demo 4: Sketch position vs time and velocity vs time graphs for when Moving Man: walks steadily towards the tree for 6 seconds,then stands still for 6 seconds, and then towards the house twice as fast as before for 6 seconds.

Demonstration in Slow Motion

Electromagnetics PhET Simulation

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.
