1. a list of corrections with the exact locations within the text
Q1 agree, remove (3-1), (3-2) and (3-3) in the abstract.
Q2 II refers to "Physics model"
Q3 (3-1), (3-2) and (3-3) were subsections. in view of the IOP formatting i am agreeable to remove the text "(3-1), (3-2) and (3-3)".
Eick, C., Meadows, L., & Balkcom, R. (2005). Breaking into Inquiry: Scaffolding Supports Beginning Efforts to Implement Inquiry in the Classroom. Science Teacher, 72(7), 49-53.

my list of questions for consideration:

'easy Java simulation' should be "Easy Java Simulation" as it is the tool name and if accepted the changes are everywhere in the paper.
page 2 Physics model
line 4 'velocity equation equation (1)'  should be "velocity equation (1)"
line last "beyond the scope of this paper," should be "beyond the scope of this paper."

page 5 after equation (6) move the "." to end of sentence "as well"
remove the 'in (1)' and 'in (2)' as the referencing in the IOP format does not have that.
for example,

'Now that we have covered the need for the same rotation sense in (1) and the same period as the earth or angular speed in (2)' should be "Now that we have covered the need for the same rotation sense and the same period as the earth or angular speed"
after 'weather satellites," should be "weather satellites."
'equation equation (3)' should be "equation (3)"

page 6 first word 'model.' should be "mode." right before 'We also got the students to think about the force that would need to be continually applied on the satellite in order for this unlikely orbit to be possible.'

By the way, I wanted to add on to the story during PS21 presentation dated 03 May 2012, on innergy award “gravity-physics by inquiry” that my colleague in school and me have been successful in publishing in a peer-reviewed journal called “Physics Education”, provisionally scheduled to be published in Jan 2013.;jsessionid=17B2BD7C11561C7C7CBA434A44887684.c1

Summary of Singapore teachers’ contributions include:

  1. Made use of Singapore’s geographical location as a teaching point, adding pride to being a Singaporean, I hope.
  2. Made a world-first research reporting (see page 1: introduction of the proof-read copy of the paper attached) in Physics education journals in the topic of geostationary orbits.
  3. Made the simulation freely downloadable from (require Java and Java3D to run) with the aim to benefit anyone in any part of the world.

I hope this Singapore physics teachers’ story can serve an encouragement to all Singaporeans to continue to “move the education forward for Singapore” and shape the world to be a better place for all humankind.

Campus Tsunami Singapore Physics Style

Update 06 November 2012:
recently, ashley tan shared on Open education matters 2.

i think is it awesome and align with my being an educator, hope the rest in the team can lead with their hearts too. Being "close-minded" on even very pedagogical sound lesson are slow to improve learning practices in Singapore (just look around, do i need to say more?), we need to be "open-minded" to the possibilities of open educational resources, and stop propagating and re-inventing lesson packages that simply live in a closed system and cannot benefit everyone in this world.

watch this video 'Why Open Education Matters' from Blink Tower

Time for us to truly lead, care inspire with your heart for the world, not just for Singapore to be the best in the world, but best for the world.

the following text are taken for ashley tan  blog, thanks prof ashley tan !
If we stopped being so close-minded, everyone wins in terms of free and open education!
Open education helps overcome:
  1. financial costs
  2. socio, geo and political barriers
  3. out-of-date information, teaching methods, and learning expectations
As the video explains, open and free is no longer associated with poor quality when
  1. the resources can be updated quickly
  2. teachers can customize content more easily
  3. quality players step into the playing field

Original Blog Post:
Original Idea: Khan Academy
Scope: Junior College
Subject: Physics

  1. Developing and implementing online resources for A-Level Physics teaching and learning
  2. Identifying high quality online educational resources to complement classroom teaching
  3. Encouraging and supporting teachers to use a range of student centred pedagogies (e.g. flipped classroom , student-knowledge reconstruction that enable better student engagement and participation in class
  4. Leveraging on crowd –sources approach to grow a pool of syllabus- relevant resources for the benefit of all teachers and students
Current Stage and my choice of platform which i can make public to benefit all humankind. Campus Tsunami Singapore Physics Style

The campus tsunami (David Brooks, International Herald Tribune [US], 5/5)

Online education is not new. The University of Phoenix started its online degree program in 1989. Four million college students took at least one online class during the fall of 2007.
But, over the past few months, something has changed. The elite, pace-setting universities have embraced the Internet. Not long ago, online courses were interesting experiments. Now online activity is at the core of how these schools envision their futures.
This week, Harvard and the Massachusetts Institute of Technology committed $60 million to offer free online courses from both universities. Two Stanford professors, Andrew Ng and Daphne Koller, have formed a company, Coursera, which offers interactive courses in the humanities, social sciences, mathematics and engineering. Their partners include Stanford, Michigan, Penn and Princeton. Many other elite universities, including Yale and Carnegie Mellon, are moving aggressively online. President John Hennessy of Stanford summed up the emerging view in an article by Ken Auletta in The New Yorker, ‘‘There’s a tsunami coming.’’
What happened to the newspaper and magazine business is about to happen to higher education: a rescrambling around the Web.
Many of us view the coming change with trepidation. Will online learning diminish the face-to-face community that is the heart of the college experience? Will it elevate functional courses in business and marginalize subjects that are harder to digest in an online format, like philosophy? Will fast online browsing replace deep reading?
If a few star professors can lecture to millions, what happens to the rest of the faculty? Will academic standards be as rigorous? What happens to the students who don’t have enough intrinsic motivation to stay glued to their laptop hour after hour? How much communication is lost — gesture, mood, eye contact — when you are not actually in a room with a passionate teacher and students?
The doubts are justified, but there are more reasons to feel optimistic. In the first place, online learning will give millions of students access to the world’s best teachers. Already, hundreds of thousands of students have taken accounting classes from Norman Nemrow of Brigham Young University, robotics classes from Sebastian Thrun of Stanford and physics from Walter Lewin of M.I.T.
Online learning could extend the influence of American universities around the world. India alone hopes to build tens of thousands of colleges over the next decade. Curricula from American schools could permeate those institutions.
Research into online learning suggests that it is roughly as effective as classroom learning. It’s easier to tailor a learning experience to an individual student’s pace and preferences. Online learning seems especially useful in language and remedial education.
The most important and paradoxical fact shaping the future of online learning is this: A brain is not a computer. We are not blank hard drives waiting to be filled with data. People learn from people they love and remember the things that arouse emotion. If you think about how learning actually happens, you can discern many different processes. There is absorbing information. There is reflecting upon information as you reread it and think about it. There is scrambling information as you test it in discussion or try to mesh it with contradictory information. Finally there is synthesis, as you try to organize what you have learned into an argument or a paper.
Online education mostly helps students with Step 1. As Richard A. DeMillo of Georgia Tech has argued, it turns transmitting knowledge into a commodity that is cheap and globally available. But it also compels colleges to focus on the rest of the learning process, which is where the real value lies. In an online world, colleges have to think hard about how they are going to take communication, which comes over the Web, and turn it into learning, which is a complex social and emotional process.
How are they going to blend online information with face-to-face discussion, tutoring, debate, coaching, writing and projects? How are they going to build the social capital that leads to vibrant learning communities? Online education could potentially push colleges up the value chain — away from information transmission and up to higher things.
In a blended online world, a local professor could select not only the reading material, but do so from an array of different lecturers, who would provide different perspectives from around the world. The local professor would do more tutoring and conversing and less lecturing. Clayton Christensen of Harvard Business School notes it will be easier to break academic silos, combining calculus and chemistry lectures or literature and history presentations in a single course.
The early Web radically democratized culture, but now in the media and elsewhere you’re seeing a flight to quality. The best American colleges should be able to establish a magnetic authoritative presence online.
My guess is it will be easier to be a terrible university on the wide-open Web, but it will also be possible for the most committed schools and students to be better than ever.

    Student outcome:

    In my paper (Wee, 2012b, p. 306), evidence on student learning outcomes include:

    Active learning can be Fun
    “…[It] is an eye opener...[we] don’t usually get to learn with virtual learning environment…and it makes learning fun and interesting”.

    “The lesson was fun and makes us think instead of just listen[ing] to teacher and remember[ing] whatever the teacher said”.

    “It makes learning much more interesting and fun. It makes us want to learn and find out more about the topic”.

    Need experience to understand

    “…it [this lab] lets me figure out the concepts rather than just listen[ing] and believing what is taught without understanding”.

    “Normally people would have to experience any physics concepts themselves through hands[-]on to really remember concepts. Lectures on the other hand may not be effective since maybe what the lecturer is bringing through us is unclear, and thus practical lessons to learn concepts is a great learning deal”.

    Simulation can support inquiry learning and thinking like real scientist

    “These kinds of lesson force us to think critically. It makes us look at the results, analyze and then find the trend within, which is a really good way to learn independently. It also gives us confidence and a sense of accomplishment when the conclusions we arrive at are correct.”

    “Such vlab[virtual lab] lesson effectively utilizes the IT[information technology] resources to enhance lessons, making physics lessons less dry. Besides, by identifying trends in values first hand, I can remember it easier rather than via lecture notes and slides”

    Need for strong inquiry learning activities

    “The activity worksheet did not generate much thinking and concept understanding, just simply presents a set of values to copy to get the answers”.

    “It [virtual lab] helps hasten the process of learning but the exchange of data [in the worksheet activities] is troublesome”.

    Need for testing and well designed simulation (N. D. Finkelstein, et al., 2005)

    Some students suggest visual and audio enhancements like “better quality so that the simulations could be more interesting and appealing” and “add sound effects”.

    A good suggestion surface is to make the “program[simulation] designed as a game , thereby making it more interactive. At the end a table can be provided and it would provide us[students] with the values. From there, we do analysis”.

    This suggestion has inspired us to design ‘C Game for concept testing’ in earlier part III.
    Appreciative learners

    “I[student] really thank you for spending time coming up with this program[simulation]. You are really an educator who cares and dares to try new things. Thanks! Hope you can come up with even better programs so that they can empower students in physics subject.”

    “Thank you teachers for spending time to develop this app[lication] :)”

    Intended benefit(s) to teachers
    Allow teachers to design productive experiential activities around the investigative data collection on one of the 4 computer models.
