Objectives
Objectives:
To construct a virtual field class in the Mountain of
Lousã, Central Portugal
To assess the resources
Activity planned for 11th grade students, to teach
magmatic and metamorphic processes
Methodology
Document analysis
Field work
Laboratory work; study of collected rocks hand samples; thin
sections analysis using a polarizing microscope
Preparation of schemes and simplified geological maps
Construction of the materials
Validation by secondary education teachers
Reformulation of materials
Validation by secondary
education teachers
Nine teachers answered to two open-ended questions:
1) Please, give your opinion about the teaching materials
(strong and weak aspects, its importance in teaching,
suggestions).
2) Would you use the teaching materials in a geology
class? Please, justify.
The answers were subjected to content analysis

Resources constructed to the
virtual field class
 Preparation phase: video
 Field class: field guide
Available in an electronic site
 Synthesis phase: discussion
topics, paper and pencil
activities for the summary
phase
 Others: glossary, information
about lithologies, pictures,
simplified geological maps,
schemes

Diagram of the electronic site
Validation of the resources
The resources were distributed by e-mail and assessed by
9 teachers (anonymous)
All the participants agreed with the structure of the virtual
class and with the resources
The resources allows the accomplishment of this type of
activity without leaving the school
The field guide was redesigned and improved based on the
identified weaker points
Conclusion
The virtual field class consists of three phases:
preparation, field class and summary
 The methodology involved documental analysis,
fieldwork, laboratory work, pictorial representation and
geological map simplification
The resources were made available in an electronic site
 Nine teachers validated all the resources and agreed to
use them in their classes
