E-Pedagogy in Coastal GI

 
Technology should enhance learning and help the students achieve the learning objectives.

The design of the lesson with the active learning process and key application of technology in mind.

Due to the pandemic, we were unable to conduct the actual fieldwork so I have used Google Earth and Google suite to conduct a simulated GI.

Blended Learning for Weather GI

My colleague, Arman, coordinated the Weather GI. With the use of technology, we were able to continue the GI into the HBL period.

Students formulated their hypotheses in Google classroom and I went through with class the hypotheses they have formulated. Three were chosen and the students collected the data using a weather tracker in school. The students then record in the Google form and the data is collated on a spreadsheet. Using the data, comparative graphs and scatter graphs are generated for the data representation.

The groups collaborated in presenting their analysis and conclusion using Google slides. Images from a group's presentation is shown below.

The use of the Google suite and Google Classroom has helped to create a more engaged blended learning experience for the students using technology.

Historical maps

Interesting historical maps to see the development of Singapore.

I like that you can allow for swipe of two maps as shown below:

1. Select the maps from the years you want to compare and then click on the 3 lines (setting) beside the year.
2. Select layer swipe followed by vertical from the pop-up menu.

Google Earth for Water and Coastal GI

We opened our classroom for teachers from another school to show how our students used their personal learning devices in class. 

We had started on 𝟭:𝟭 𝗣𝗲𝗿𝘀𝗼𝗻𝗮𝗹 𝗟𝗲𝗮𝗿𝗻𝗶𝗻𝗴 𝗗𝗲𝘃𝗶𝗰𝗲 using iPad in 2019 and it was a real blessing for 2010. I must thank our HOD ICT in rolling out the 1:1 PLD program and also ensuring the infrastructure support such as 𝗔𝗽𝗽𝗹𝗲 𝗧𝗩 so that we can mirror our iPad screen to the projector screen easily. 

Of course I am also thankful that we are already on the 𝗚𝗼𝗼𝗴𝗹𝗲 𝗦𝘂𝗶𝘁𝗲.The ease of organising the lessons via the 𝗚𝗼𝗼𝗴𝗹𝗲 𝗖𝗹𝗮𝘀𝘀𝗿𝗼𝗼𝗺 and the ability for the students to use technology in their learning. The Sec 3 had fun on an overseas virtual fieldwork in UK and made interesting findings on 𝗚𝗼𝗼𝗴𝗹𝗲 𝗘𝗮𝗿𝘁𝗵. The Sec 1 love that they can explore the field sites along the Punggol waterway from their seats using 𝗚𝗼𝗼𝗴𝗹𝗲 𝗘𝗮𝗿𝘁𝗵. They would have gotten all wet if they had gone there for their GI as it started raining so heavily. 

Sec 1 

We completed stage 4 of our Water GI using 𝗚𝗼𝗼𝗴𝗹𝗲 𝗖𝗹𝗮𝘀𝘀𝗿𝗼𝗼𝗺, 𝗚𝗼𝗼𝗴𝗹𝗲 𝗘𝗮𝗿𝘁𝗵 as well as 𝗚𝗼𝗼𝗴𝗹𝗲 𝗦𝗹𝗶𝗱𝗲𝘀 for collaboration. I have placemarked the field sites and embedded the data they had collected from their water test. 








The groups entered the data into 𝗚𝗼𝗼𝗴𝗹𝗲 𝗙𝗼𝗿𝗺 and the teachers were able to help the classes collate their data for the to analyse on the 𝗚𝗼𝗼𝗴𝗹𝗲 𝗦𝗽𝗿𝗲𝗮𝗱𝘀𝗵𝗲𝗲𝘁. They were able to make observations of the field sites using the street view and explained how the features they have observed on 𝗚𝗼𝗼𝗴𝗹𝗲 𝗘𝗮𝗿𝘁𝗵 showed human activities and the impacts on the waterway. They are able to collaborate with their members to present the conclusion on their GI using 𝗚𝗼𝗼𝗴𝗹𝗲 𝗦𝗹𝗶𝗱𝗲𝘀. https://sites.google.com/a/moe.edu.sg/sec-1-geog-2021/2021-water-gi 

To show the changes overtime I have also used Juxtapose JS to create a time slider using 𝗚𝗼𝗼𝗴𝗹𝗲 𝗘𝗮𝗿𝘁𝗵 images from 2010 and 2020.

Sec 3 

We used Google Earth to understand coastal studies for map reading. I have integrated a topographical map into the 𝗚𝗼𝗼𝗴𝗹𝗲 𝗘𝗮𝗿𝘁𝗵 file. The students visited the south of UK (Seaton) and learn how the map representation came alive with 𝗚𝗼𝗼𝗴𝗹𝗲 𝗘𝗮𝗿𝘁𝗵 showing them the actual site of coastal landforms they have studied. They also better understand the concept of space, scale and place as they made measurements of the spit and made observations of how the spit has affected human activities in the area. https://sites.google.com/a/moe.edu.sg/sec3geog/google-earth 

 This was continued from the Coastal GI using 𝗚𝗼𝗼𝗴𝗹𝗲 𝗘𝗮𝗿𝘁𝗵, 𝗚𝗼𝗼𝗴𝗹𝗲 𝗦𝗽𝗿𝗲𝗮𝗱𝘀𝗵𝗲𝗲𝘁 and 𝗚𝗼𝗼𝗴𝗹𝗲 𝗦𝗹𝗶𝗱𝗲𝘀 on 15 Mar. With Google Earth, the students visited the place marked field sites and made observations of the environment. They annotated a field sketch to explain the coastal processes which could have affected their investigation. It is blended learning as I also included the fieldwork simulation of measuring the sediments I had collected. They did the wave frequency via a pre-recorded video. They also measured the gradients on the models I have created. https://sites.google.com/a/moe.edu.sg/sec3geog/geographical-investigation/gi---coast/2021-coastal-gi-fieldwork-simulation

Climate Change resources

Useful interactive on climate change shared by my colleague.

https://storymaps.arcgis.com/stories/6942683c7ed54e51b433bbc0c50fbdea







Great e-resources from Conservation International Asia Pacific with videos, worksheets and quizzes!

https://www.conservation.org/singapore/virtual-learning

The 5 episodes at a glance:

EPISODE 1: WHAT IS CLIMATE CHANGE?


EPISODE 2: WHY IS CLIMATE CHANGE
HAPPENING SO FAST?

EPISODE 3: HOW DOES CLIMATE CHANGE AFFECT US?

EPISODE 4: HOW CAN NATURE HELP US FIGHT CLIMATE CHANGE?

EPISODE 5: WHAT CAN WE DO TO CHANGE
THE COURSE OF CLIMATE CHANGE?

Within each episode, you will find resources that could complement your lessons:
  • Short video explaining and exemplifying the question with Singapore examples
  • Downloadable activity sheets to engage students in school or at home
  • Downloadable educator guides which include discussion questions for the videos and how to conduct the activity sheets
  • Pop quizzes to supplement students’ understanding of the video

Google Earth provides opportunities to explore geographical issues such as Climate Change.
Other than the Google Earth kmz file 4 degrees which shows areas most affected by global warming in terms of temperature changes.
https://sites.google.com/a/moe.edu.sg/sec3geog/google-earth, students can explore cities which will be most impacted by the rise in sea level in the simulation with Voyager in Google Earth. The file on sea level rise and the fate of coastal cities can be found under the category Nature in Voyager.



Showing the spatial extent of impact with a 2 degree increase in global temperature as compared to a four degree increase on Mumbai in India.

Coastal erosion at Changi

 Changi beach is a popular place for beach and water activities for many. However, the waves are strong and coastal erosion has taken place.

The Changi beach is a place where many families visit to relax and take part in water activities.

However, the coastal land is so badly eroded that it will give way soon.

Sand bags have been placed to protect it from erosion. How effective do you think this will be?


The erosion is so bad that the roots of trees are exposed.
Seawall protecting the another stretch of the coastal land and chalet behind it in Changi. However, you can still see the erosion at work in the foreground.

Look at the coastal erosion threatening the footpath behind it.


Weep holes on the seawall to allow the ground water to be drained so that the soil will not be too saturated and put pressure on the wall and damaging it.

Photos above taken on 20th and 23rd Dec 2020

Imagine the waves were so strong that it allowed for surfing on 15 Jan 2021!

Tanjong Rimau

Super excited to finally see Tanjong Rimau @ Sentosa again after 28 years! Brought my first batch of students from Rangoon Sec for fieldwork. We were measuring the beach profile and making observation of the cliff features such as the notch and cave. Before the hotel opened next to Tanjong Rimau. Managed to be there via my staycation as I accessed this part of the beach from the hotel's nursery.
Sentosa Nature Discovery has developed a lesson plan based on a video of this area using a drone. I have posted this earlier. 


The cave is deepened with erosion

Studying the geology of Tanjung Rimau with the guidance of EOS. So much to learn about history of tectonic activities through rocks.
