PLANNING OF VIRTUAL FIELDWORK

01

FROM THE EYES OF TEACHERS

(5)

Rationale

(6)

Rationale for Virtual Fieldwork

After CCA Restrictions

• Insufficient resources / days to conduct real fieldwork.

• Shortening of usable teaching time.

• Curriculum needs: FBQ / Fieldwork skills

• Fieldwork skills are learnt in the field, in the wild and in everyday life…

Teachers led field-work / visits

Fieldwork Based Assessment (2022)

There is still a genuine need for learning fieldwork skills on the basis of

• effective learning & cognitive development

• generic skills learning

• handling public assessment

Managing River Environment Opportunities & Risks

Disappearing Green Canopy

(8)

Why there is a need to use Virtual Fieldwork / Fieldtrip

SHOCKINGLY

Majority of students NEVER visit a REAL natural river in real life.

Some believe water comes from

TAPs.

(9)

What should students learn about local rivers / drainage basin?

1. Many tributaries

2. Mostly short / transacted rivers 3. Flow through urban areas

4. Large seasonal variation in discharge 5. Sharp change in altitude

River and our environments

Conclusion

(10)
(11)

Where?

• There are so many rivers in Hong Kong.

• Many urban / concealed / dammed channels.

• Question:

• What is the enquiry topic / issue for fieldwork research in fluvial environment?

• Pre-trip preliminary data analysis

• Safety

• Available tools / equipment

• Accessibility

• Feasibility

• Data quality

(12)

The hardship… From the perspective of geographical concepts

• Source of river?

• Mainstream of river?

(13)

Testify the changes of discharge / velocity / erosion / deposition / transportation rate etc

Fluvial processes

Validate whether Hong Kong has various erosional / depositional landforms along river courses.

Fluvial landform / morphology

Interview residents / users on the perception of a good / useable river.

Rivers and Living Environment

Decide whether the existing flood management is appropriate / needs for extra flood management.

Flood Management

What issues / topics are suitable?

(14)

How to take field records?

• Ng Tung River is chosen

• Its large catchment, long river (13km)

• Relatively natural

• Relatively accessible by public transport

• Then, the following are considered:

When?

How?

What?

(15)

Sampling method

• Appox. equal distance

• Systematic point sampling

• Each point is about 1.2 km in distance

• Capture represented fluvial characteristics & changes

along river sections

(16)

• Upper course

• Which stream should we record?

• How can we reach the river?

• Is it safe / legal to walk in the river?

• How to deal with pests / weeds?

• Lower course

• How to position the accurate point / ensure data validity?

• How to log more useable data from the channel?

• How to take best photo to represent the point?

How to prepare for the

virtual fieldwork materials?

• Using bicycle to travel to field sites in a day.

• Accurate fluvial characteristics of the day.

• Some sites are inaccessible by vehicles.

• Reduce biases.

• Safety concerns

• Dogs

• Slopes

• Pests / Mosquitoes

• Exposed location

• Rocky / slippery channel

• Trespassing private land

• Lack of mobile signal

• Exhaustion

Reasons for using 2 different APP / Software

Google Earth (Presentation)

• Can show terrain / map

• Clear understanding of environment

• Easy to navigate

• Less details / blurred view

• Service may be suspended

• Best for

• Understanding the field sites

• Pre-Trip

EduVenture VR

• Authentic view

• Can show videos / audios

• Guess the velocity, noise level etc

• Can set questions / tasks

• More details (add data set)

• Need to install APP / download much data

• Need specific tools

• e.g. VR Google / VR Headset

• Best for

• Observing and recording

(26)

Using Virtual fieldwork….

Advantages

• All weather

• Easy to monitor discipline

• Safer

• Lower costs

• Time-saving

• Easier to cater SENs / diversity

• Reliable (data wont change)

Disadvantages

• Objective

• Little training on using authentic field tools / equipment

• Man-induced errors

• Lower validity of data collected

• Mostly second-hand data

• Less flexible research design

• fixe route / tasks

• restricted to data collected

From the Fieldwork Perspective

(27)

Adolescent loves to play and curious about new environment.

• During authentic fieldwork, it provides space for cultivating creativity, problem-solving and effective communications with other classmates.

• Cannot control & give instant feedback.

1 Less social / peer learning

3 Hard to conceptualize abstract concepts

2 Lower degree of

students engagement

4 Fewer physical development

• Collect field data of Ng Tung River to learn categorization / summarization / coding skills.

• Justification of data collected and further improvements in future field enquiry.

OPTIONAL

• To do a self-designed geographical

issue inquiry on river (e.g. self-determined methodology / collection of data etc)

Virtual Fieldwork Worksheet Design

• To compare the findings with repeated test at the sites in VFW.

• Assess the potential risks / difficulties to conduct fieldwork in the selected sites.

• Developing / refining own field enquiry question based on the virtual pre-trip at the site.

2) Collection: One-for-all or multiple collection?

3) Presentation: Data reliable?

4) Conclusion: Can we make a solid and sound conclusion?

5) Reflection: Room for improvement?

Reflective Questions for Students after VFW

• Students need to fully aware of the relationship between precipitation (rainfall) and discharge in Hong Kong.

• Only take a virtual fieldwork once may not understand the actual hydrological characteristics of Ng Tung River.

* Not to scale

Perceived Constraints for Virtual Fieldwork

• Biological threats?

• Restricted access?

Planning

• Insufficient primary data to validate secondary data

 Data Presentation

• Site selection?

• Choice of sampling?

• Sufficient data collected?

Data Collection

• Accumulated biases &

superficial interpretation may lead to invalid conclusions

Conclusion

Fixed route and a fixed screen.

• Can only provide more verbal, imagery information of the site on a particular day.
