Students, lessons learned, and goals

Dr. Christine Royce reports on another busy day in Shanghai.


Thursday, November 18, 2010

Today was the day for students, lessons, and—for me—personal goals. Now, this may sound like the students are those in the classes we teach or observed and you would be correct. However, the word student took on a much more meaningful connotation today for me and I hope for others. We, the participants in the conference on both sides were the students in that we were learning from each other, our colleagues, and the experience at hand. We also visited schools where we were able to interact with students allowing us to be in a familiar setting.
The morning was spent in concurrent sessions on similar topics from yesterday. The structure—the Chinese present a series of case reports related to the topic, engage in discussion, and then we, the Americans, present on the same topic. While the original intent was that we would do similar things, there was something lost in translation at some point. The group from NSTA convened teams that would present the topic as a team approach, having worked several months on our presentations. I appreciated this approach in that it allowed me to better know some of my colleagues—David, Walter, and Piyush—as well as have a discussion (albeit via email or conference call) on the topic at hand. Our topic was how we prepare teachers in this country, which focused on a historical overview of the structure of teacher certification. In contrast, we received different examples of programs that work with teacher preparation from our friends in China. Each was interesting and informative, just simply assembled in a different manner than we expected.

One example of our becoming students today dealt with the translation. While the past two days were simultaneous translation, today’s approach was sequential translation—we say something and then it is translated. This actually was an interesting experience, identifying where to break to allow enough information to be provided, but not too much that the translator would lose the concept presented. Back and forth went the sharing of information—first in Chinese to English and then English to Chinese. My lesson learned, related to the preparation of presentations, is that it may not always go according to the plan given; however, in this case the task was successfully accomplished if you stay flexible. Staying flexible is not always an easy goal—so today was a great reminder of how much you can learn if you do remain flexible.
We were also students learning about the other countries programs and efforts to improve science education. For example, one presenter was sharing that the Chinese education programs are attempting to move away from traditional programs towards competency based programs. This point was reiterated on the American side in that we are doing the same. One aspect that did amaze me during the presentations was our counterpart’s ability to interweave examples of their programs and efforts with those of other countries. Singapore, Taiwan, Australia, and France were but a few of the countries that were mentioned. Usually the connection was related to something the other country has done that China has adapted or modified. If we are all lifelong learners—it was clear today that I—and I would venture to say, some of my colleagues—aren’t as skilled at knowing what China is doing as quickly as they know what we are doing. The lesson I learned from this aspect is that it is a large global world, and too often I get caught up in the happenings within America only. My goal for the future is to broaden my horizon to learn more about science education efforts worldwide.
Following lunch, one of the highlights of the trip thus far: visiting a primary school and high school. First we were treated to a presentation at Haihua Primary School, which would be considered a “key” school, or as we call it, “magnet school.” This elementary had as an emphasis science and technology. Much of the focus was related to the environment and man’s impact on the environment. Upon entering the room, the delegation naturally gravitated to the back of the room where students were sitting at different stations, ready and willing to show us their activities. After being gently guided to our seats for a presentation about the structure and purpose of the school, we were then able to interact with the students, ask them questions, observe them building or constructing things, and get a sense some activities that were identified as lessons. Activities included using paper magazines to make ecological holders for pencils as well as constructing cars from kits provided. Several students also demonstrated two “magic” activities which had a connection to science content. It was enjoyable to meet these students, most of which could converse with us in very good English (thank goodness, since we weren’t able to converse in Chinese). They answered our questions, showed us their activities, and were generally pleased to represent their school.
This was one of the factors that came to the forefront at both schools—a sense of pride in what they were doing and a sense of belonging to their school. Students at the high school were engaged in demonstrating similar activities as well—robotics and a biology investigation. While not as conversant with us, the sense of enthusiasm was present for what they were doing. We had a presentation and question-and-answer session with the administration and teachers at Luwan Senior High School. One of the interesting answers to the question “What are your challenges in the classroom?” related more to the big ideas than what we often hear if American teachers were to answer this question. There are many reports that describe teacher challenges as classroom management, class size, impact on time, lack of parental involvement, as well as a myriad of others all of which do impact learning and the classroom environment. The teachers talked about average class sizes of thirty-five students and having less instructional time in the week than we have. The teachers provided reasons such as “breaking traditional thinking of the students,” how to get them to think independently without the help of a teacher, and “how to make the lesson more interesting to meet the needs of the students” were answers provided. My lesson learned here is that we often focus on the logistics and process of running the classroom, which I know is important, and often forget that there are bigger ideas to consider such as those mentioned by our Chinese friends. My goal is to try and remember the bigger picture even when the day becomes overwhelmingly filled with those minor details.
Finally, the last student experience of the day was an individual one. I was fortunate to have a former graduate student and graduate assistant Tian Shen join our team for today’s presentation. Tian was at Shippensburg University for two years obtaining his Master’s degree in Curriculum and Instruction and has since returned to his home city of Shanghai, where he teaches at the Shanghai International School High School Division. While not a science teacher, as he teaches 7th grade math, Tian was able to join the team and provide comments related to his experience of taking classes in a teacher preparation program during the session. The excitement he demonstrated at being asked to participate in this event made the day absolutely wonderful. He was an outstanding student in our department and is obviously becoming a well-respected teacher at his school. The most important lesson of all is that involving your students engage in opportunities such as these as well as those that are present in your classroom allows them to grow. What seems like a simple goal—involve more students in opportunities that meet their needs and desires is often overshadowed by the two lessons mentioned above—only focusing on the local agenda, the here and now if you will, as well as becoming consumed by the daily logistics and not looking towards that big picture. My final goal that I set today is to involve more students in opportunities and programs in which I am involved, to help broaden both their and my own views of education in a global society.

Dispatch from China

The delegation seems to be feeling a bit more comfortable with the surroundings and food. The hotel is a couple of blocks from “the Bund” (the historic area along the Huangpu river) and the Yuyuan Garden.
So far the conference has hosted speakers from China (Ministry of Education, Higher Education, and Informal Education) and the U.S. (Higher Education, Curriculum Developers, informal education). Most of the talks were at a higher level without much mention of science instructional approaches or strategies. I was surprised to learn about the scale of the Chinese education system. There are 1.3 billion people in China and 200 million K–12 students. Approximately 8.5 million students are children of migrant workers, and 24 million students’ parents leave during the week to work in factories. The class sizes average around 35–50 students.
There are 17 million teachers in China and the professional development for teachers (including science teachers) is required; one third of it is provided by the government and the rest is provided by the local school. Teachers are certified for 5 years and need to receive continued support to become recertified.

There is a national science curriculum (Learning by Doing) and standards. The topics are essentially the same as ours and include guidelines, similar to U.S. science education standards, which decrease doing some things and increasing others. A couple of chemistry examples include less chemistry calculation and demonstration experiments or increasing the teaching of ecological balance, and connecting to life experiences.
Inquiry is a focal point and appears to be very important to the Chinese. However there was agreement with some of the U.S. speakers that the concept of inquiry is not well understood or implemented in Chinese classrooms. The issue of assessing inquiry seemed to leave all speakers challenged to provide a good answer. The Chinese teachers started to ask questions today and were quite comfortable with asking pointed questions.
Three themes really stood out today: Equity, assessment, and implementation. The challenge of the scale of China is mind boggling. China has so many students and teachers that the implementation issues are huge. The delivery systems are massively designed; however it is not clear how they are actually working.
There are 40 different groups of people within China and the wealth of China is very uneven, particularly among the urban and rural communities. Assessment is used mostly as a filter of students rather than being used to improve instruction. Technology is helping provide these and some instructional approaches across the country.
More soon …

Maps and models

By Mary Bigelow

Posted on 2010-11-18

Click here for the Table of Contents


Both of these words can be nouns or verbs, and both interpretations are essential in science, as described in this month’s edition of Science Scope. Students use models and maps as learning tools; they also can model design processes or map their understanding of a concept.
It appears that many of these articles on maps and models are related to the Earth Sciences. Using Google Earth to Study the Basic Characteristics of Volcanoes goes way beyond the build-a-volcano models of yesterday to using a technology application to study real volcanoes. And if you can’t take your students to a cave, the author of Caving in the Classroom describes how to bring a caving experience to your students. She shares activities, rubrics, and resources for this simulation. Check out other resources in SciLinks Caverns.Students seem to enjoy working with maps, with a renewed interest in them thanks to GPS technology. Seafarers, Great Circles, and a Tad of Rhumb: Understanding the Mercator Misconception illustrates some misconceptions people have about the Earth based on map projections. I gained a new vocabulary term (rhumb line), too. The SciLinks topic Mapping has lists of resources to supplement those recommended in the article.

In Astronomical Scale of Stellar Distances Using 3-D Models, students demonstrate their understanding by creating models. Building Models to Better Understand the Importance of Cost Versus Safety in Engineering has ideas for introducing students to engineering projects such as building a tower. Both of these articles include teaching suggestions, rubrics, and resources. If you want to expand the engineering projects, consider some of the projects in the SciLinks Bridge Structures.
“Model” can also mean a plan or prototype. A Revolutionary Model of Professional Development compares traditional teacher training workshops to differentiated professional development.
The Scope’s Scoops feature has summaries of current research in various topics. These reports could be used by students, too, for extra reading on the topics. The topics this month could be expanded with information and activities found in SciLinks: Meteors, Dinosaurs, the Brain, and Black Holes.

Science bridges many barriers

By NSTA Web Director

Posted on 2010-11-17

An update from Dr. Christine Royce, a member of the NSTA team at the Sino–US Science and Education Forum in Shanghai.


Wednesday, November 17, 2010

Today in one sense was a long day—this was heard stated by many of the participants here. It wasn’t that we were uninterested in what was said; it wasn’t that we started any earlier or finished any later. It might have felt like a long day since as one person stated –the adrenaline rush of being in a foreign country on such a journey is starting to wear off and jet lag may be setting in just a bit. The reason I think it felt long to others and specifically the reason it felt long to me was simple—with the exception of tea breaks (which by the way is customary everywhere you go) we sat. To clarify—we sat on our butts all day and listened to speakers—eight in all. Now please don’t get me wrong—the topics the speakers presented on were wonderful—informal science education, preparation of teachers, curriculum design, and research relating to improving the field. There will be more on these later, however to get back to why the day felt long—it’s because the consensus among an informal survey of participants was—we rarely ever sit that long. One person even went as far as to comment that we now know what our students may feel like at the end of a day.
Today’s presentations from both sides presented interesting and informative perspectives to consider. One of the main points that jumped out towards the end of the day as Elizabeth Mulkerrin was speaking was when she said something like science is the bridge to helping students learn in reference to a particular program she was highlighting. That phrase summed up the entire day for me. Science truly bridges many barriers.

One of the feature presenters from the Chinese delegation spoke about two priorities that the Chinese government has set for education in the next ten years—equity and quality. Equity in China means exactly what it means in the United States—addressing the situation of students in poverty, ethnic minority areas (an interesting fact that we learned today was that the Hun group was the most prevalent in China), bringing equity to all schools and eliminating key schools, as well as allocating more resources for schools. Dr. Wang Dinghua discussed the need to address dropout rates, support special education and migrant workers (not something I ever really considered, to be honest) as well as their equivalent of “latch-key kids.” Point by point he could have been talking about issues and concerns in the United States. Quality again was repetitive of what we hear regularly—improving all schools, laying a solid foundation for future development and education. However—there was one that we as Americans are just starting to see on the horizon (fingers crossed that the direction of travel continues) and that is having all students complete their studies with science literacy. He pointed out that the 3Rs are important in helping people communicate, however science literacy was important in helping the country move forward as a nation. He connected it to energy, the environment, sustainability and what he referred to as a “higher R requirement”—that of responsibility. Responsibility to each as an individual, society as a whole, and the future of the country.
As I understood his presentation, science is the key connector between all aspects of the future as the Chinese see it—it bridges the past with the future. Dr. Dinghua continued to discuss the components that go into making their national curriculum (which does have a certain percentage determined by the local provincial offices) better and future- looking—teacher efficiency, a reduced workload for student homework, the need to foster creativity and continuing to strengthen hands-on experiences of the students. His point was further reflected by a statement in Dr. Liu Enshan’s presentation on biology curriculum later in the day. He stated that part of the national agenda was in order to “maximize human capital to build a creative country; science education should play a critical role in general education.” He further discussed that science is taught in grades 3–11 with integrated content being covered up through grade 9 followed by discipline specific topics for high school. Dr. Enshan focused on a change that has been implemented into the biology curriculum in recent years—that of inquiry.
Which led nicely into the session presented by Dr. Alan McCormack and Dr. Karen Ostlund. Alan and Karen focused on how to engage students, including preservice educators, in inquiry based experiences. Discrepant events were presented which resulted in an equal reaction between the Americans and Chinese—a look of wonder as well as a brief bit of confusion as the water should have come right through the glass that had a hole poked in it. What followed was another example of science serving as a bridge.  Even though we were still SITTING, they had us do the “fish inquiry”—you know the one—where a red fish cut out of cellophane like put on the palm of your hand and you observe what happens to it … does it curl up, have its head move or its tail. Next they distributed simple materials and asked us to design an experiment to test our hypothesis as to why the fish moves. If you can picture Chinese educators who speak little English, and American educators who speak almost NO Chinese, sitting side by side in an auditorium, communicating with each other through pictures and hand gestures designing and conducting an experiment—to observe the event was unbelievable but to participate in the opportunity was amazing. The act of “doing science” crossed barriers of language and allowed us to engage in a meaningful way with each other thus making additional connections between individuals.
In considering Elizabeth’s statement and the events of the day—science truly does bridge many barriers that often divide individuals and countries. Classroom science bridges the achievement gap according to information presented by Dr. Janet Carlson and Dr. Arthur Eisenkraft today during their presentations. Science information brings nations together for summits on global warming, nuclear energy, and natural disasters. I am not saying that everyone reaches the table with the same goals or agrees on the desired outcomes—but that too is part of science—presenting your side and evidence in a persuasive argument and then should it come to it– agreeing to disagree—but continuing the conversation and pursuit of scientific knowledge. Science education has brought together all of the people attending this forum who will now have connections to maintain in the future. Some may be intermittent, while others may be regular. The important point that I learned from today is that there are many ways to cross a divide or conquer a barrier—and science education and the experiences at this forum will help us all to build many bridges and connections well into the future.

Notes from day 1 at the Sino-US forum

By Francis Eberle

Posted on 2010-11-17

NSTA Executive Director Francis Eberle

NSTA Executive Director Francis Eberle


The NSTA delegation of science educators landed Monday night and began the inaugural 2010 US–Sino Forum in Shanghai on Tuesday. The purpose of this trip is to learn about Chinese science education, and to identify any features, characteristics or practices that will help in teaching science in the U.S. We are also looking forward to an exciting cultural experience in the one of the fastest growing economies in the world. Shanghai is the largest city in China with a population of about 20 million people in a country often quoted as “highly motivated” and “beating” the U.S. in the development of highly educated scientists and engineers.
Our host, the China Association of Children’s Instructors of Science (CASCI), is NSTA’s counterpart in China. Our secondary host is the China Association of Science and Technology (CAST), which is an organization run by the government of China. This is an important distinction which I will discuss later. They have made the beginning of our visit very comfortable and have made us feel welcome by providing us with translators, a tour guide to get around, and by providing lots of food (which I will comment on later, too).
During the first morning, about half of the NSTA delegation spent time at the Shanghai International Forum on Science Literacy of Precollege Students. In its sixth year, this event is an opportunity for science educators from France, the U.K., the USA and China to interact and promote the development of precollege student science literacy. Dr. Jo Ellen Roseman and Ted Willard from the AAAS/Project 2061 represented the U.S. We were able to hear several presentations from two countries and see the award ceremonies for many science educators from around the country. (The background music for as the awardees went up to the stage was the theme song from the popular 1959–1973 TV show Bonanza.)
The NSTA/CASCI forum began after lunch with introductory speeches and then keynote speeches from Dr. Norm Lederman from the Illinois Institute of Technology and Dr. Wei Yu from the Research Center for Learning Science in Southeast University.   Dr Lederman provided a clear history of reform efforts in the U.S over the last ten years and concluded describing the challenges ahead with many of the reform programs. Dr Wei described the reforms efforts in China over the last 50 years, but spent most of the time on a recent large-scale effort called Learning by Doing in Science.
It was remarkable that she talked about many of the same things that science teachers say are key features of science education in the United States, such as experiential learning, inquiry, and Internet based communications. She quoted Piaget and other constructivist educators. She also spoke about several issues related to the unmet promises of the Learning by Doing effort in China, such as inadequate resources and qualified teachers.
One issue that differed greatly was the effect of the one child policy in China on children’s empathy and communication skills, particularly in the rural areas of China. Dr. Yu posited that because so many children in China are growing up as single children they have little empathy for others and lack many of the people skills that a child in a family with multiple children might develop growing up with siblings. She felt that this was a critical weakness and had to be addressed by the Chinese education system.
The second day begins with presentations from both U.S. and Chinese science educators.

Sino-US forum gets underway

Dr. Christine Royce reports from the Sino–US Science and Education Forum in Shanghai.


Tuesday, November 16, 2010

Where did Monday go … well, due to the time difference, the delegation didn’t actually arrive until Monday evening … so today was the first day of the Forum. Some members of the delegation headed over this morning to an optional event—the Shanghai International Forum on Science Literacy of Precollege Students, while others took advantage of the down time to either relax, sleep in, or wander around the Yu Garden area, which is home to a series of shops and bazaars selling everything from silk scarves to Chinese tea to pearls.
The actual opening of the US–Sino Forum began after lunch at the Sinan Building which is where we heard the opening ceremony and keynote speeches. Opening comments were given by Mme. Chen Saijuan from CACSI (Chinese Association of Children’s Science Instructors” and Dr. Francis Eberle, Executive Director of NSTA. During Francis’s opening comments, he remarked that the differences between our countries are as important as the commonalities as we have much to learn and share. He further commented that the future of both countries is tied to science and education. This struck me as an important point, because earlier that morning, I took full advantage of trying to regulate my clock by sleeping in a bit and then wandering around Yu Gardens. While there with a colleague Steve Rich, we came across a group of upper elementary school girls in their uniforms, complete with backpacks and what appeared to be a worksheet in hand. Steve and I immediately assumed that they had a series of tasks to complete while there as they looked like they were searching for specific locations (albeit stopping and sharing in the treats for purchase as well). It was interesting to see these school aged children from China acting just like I have observed school age children from the United States doing. They were writing things down when they “got an answer”; laughing and joking with each other and they were obviously engaged in this time outside of the traditional classroom.

I have yet to visit a Chinese school so I am not sure what their traditional classroom even looks like, however, there were many similarities between my observations of these children and those from my home state. I don’t know what subject they were trying to do or even if they were there for school reasons. I am assuming so as it was mid morning which is after the “normal” school start time and they were in uniforms complete with backpacks. I noticed the similarities first, rather than the differences which brings me back to Francis’s opening points. There are many similarities to my home world even in this bustling city. I have yet to feel “out of my element” or “in a foreign land” if you will—rather I found it easy to read the street signs while on the bus yesterday and today (even though I have no orientation as to where I am going); could locate the traditional types of stores—convenience stores, fresh fruit stands, tourist places and yes—even a Pizza Hut and McDonalds; and most of all, I was able to navigate around a new city with some basic skills and a map. The hardest part of the trip so far was figuring out how to turn the lights on in my hotel room and then keep them on (one must insert their key card into a wall slot while in the room for the lights to remain on—once removed, the lights shut off in a few minutes which is one way to conserve energy I guess).
Following the opening comments, we had the pleasure to hear a keynote speech from both the Chinese Science Educators and the US delegation. Mme Wei Yu is an academician of the Chinese Academy of Engineering as well as holding many offices in associations such as the Chinese Association for Science and Technology. She is internationally cited for her efforts in promoting “Learning by Doing” which is an inquiry-based science education project for grades one to six. Her presentation focused on her work in designing and implementing “Learning by Doing” and the successes she has had as well as the challenges she has faced. One of the points she reiterated was that science and education are important to strategic issues that affect our future. She also stated that science teachers are essential to reform … so we must share both countries experiences of teachers because we can learn from each other and inspire each other.  The US Keynote was given by Dr. Norman Lederman, who is Chair and Professor of Mathematics and Science Education at the Illinois Institute of Technology. His speech also focused on the promise and challenges of science education reform in the United States.
Throughout both presentations, many commonalities emerged—that both countries have teachers who put effort into and are dedicated to their fields; that global issues need to be addressed and worked on together—because we have much to share with each other; that evidenced based and science based reform requires teacher training and money; and that both the US and Chinese views on elementary science education are not always at the forefront of the daily teaching agenda since there is no mandatory test that measures young student learning. The first several were interesting to hear, but the last one was somewhat of a surprise for me. It appears that both countries teachers of science are fighting to make science a subject that receives priority in schools. The differences were few but demonstrated the major difference between our countries. China has a national curriculum and can guide what happens in all schools from as Mme Wei Yu stated a “top down approach” where as the US has local control of schools. Another difference that was illustrated related to Dr. Lederman’s statement that often there is “teacher resistance to change” in our country since it is often a swinging pendulum in the education arena, however, teachers “follow” the directives that are provided by the Ministry of Education in China. Before I get emails, I am not making a judgment regarding which it should be or why as I do not have enough information about the Chinese system to draw a fair comparison, rather I am just simply stating one difference that was clearly pointed out.
Regardless of which you focus on, the similarities or the differences, there is no doubt that both countries delegations have entered into the inaugural US–Sino Forum on Science and Education with open minds in order to build on a commonality—an obvious passion for our field and desire to improve education for our students.

Conference Exhibit Hall

One of the conference highlights is visiting the exhibits—a great way to preview materials or software, create a wish list of equipment, add to a professional library, or meet new people. Many vendors have give-aways such as maps, pens, rulers, posters, samples, or brochures that, although they don’t seem like much, are really helpful to teachers.

Models and modeling

By Mary Bigelow

Posted on 2010-11-15

When I’m at an NSTA conference, I try to attend a session on a topic about which I know very little. This time, I saw a session entitled Epigenetics: Beyond the Central Dogma. After a brief discussion of research on how the environment interacts with the epigenome (a layer of biochemical reactions that turns genes on and off), I must admit I was still a little lost. But then the presenter Louisa Stark from the University of Utah guided us (using a handout and a video) through the process of making a DNA and histone model, demonstrating accessible and inaccessible DNA. My own personal lightbulb went off! She shared two websites: Learn Genetics and Teach Genetics that include sections on epigenetics.  I spent quite a bit of time exploring them on my own with more light bulbs going off in my head!
A session on the modeling project WikiWatershed was presented by a team who is developing this amazing resource. With this model, Susan Gill (from the Stroud Water Research Center) and Nanette Marcum-Dietrich (from Millersville University) modeled how students can explore their own watershed environment using real-time data. They’re starting with the Delaware River watershed in southeastern PA, but it’s easy to see the potential for a nationwide (or even global) expansion. Several teachers (Elizabeth Harvey, Isabel Pilling, and Thomas Gaffney from The School District of Philadelphia and Melissa Hess from the Conestoga Valley SD) shared their classroom experiences in using the model and lessons they are developing.
