Link:
Yesterday, we ended the ‘Force and Motion’ unit and solved some
problems.
Today, we will see that the matters can charge by gaining or losing
electrons.
Tomorrow, we will see the charge distribution of charged
objects and electric force.

14. Teaching
strategy:
We found “inquiry based learning” method
appropriate for this lecture. Inquiry-based learning is a student-centered and
teacher-guided instructional approach that engages students in investigating
real world questions that they choose within a broad thematic framework.
Inquiry-Based learning complements traditional instruction by providing a
vehicle for extending and applying the learning of students in a way that
connects with their interests within a broader thematic framework. Students
acquire and analyze information, develop and support propositions, provide
solutions, and design technology and arts products that demonstrate their
thinking and make their learning visible.
15. Steps
which will be followed during lecture:
a) Introduction
to new unit.
In this part we will give
an introduction to the electricity unit and talk about the previous knowledge
of students related to electricity.
b)
Showing a video and talk about it.
In order to attract students’
attention we will show a video which related to the static electricity. Then we
will discuss the reasons of the situation in the video.
c)
Make groups and distribute the activity sheets to
groups. Doing activities and controlling the students while they do demos.
After discussing video, we
will distribute the activity sheets to students and give them enough time for doing the activities and answer the
questions in this sheets. There are four different activities and groups could
be formed by 3 to 5 students. While students do the demos, we will control and
help them about their faults.
d)
Distribute evaluation sheets about group performance.
After all groups finish their
activities we will distribute evaluation sheets and ask them to answer in 1
minute.
e)
Let students to explain what they have done.
After collecting evaluation
sheets, we will let students to explain what they have done in each activity.
Every group will choose a talker for their group and these students will
explain groups’ ideas.
f)
Explain briefly the students’ results.
After students finis their
explanations, we will briefly explain their results and if there will a wrong
thing in their explanations we will correct them.
g)
Give the concept effectively. Talk about similar
examples.
We will again talk about the
concept and give effective explanations again. After giving concept, we will
talk about two similar examples with the help of the slides.
h)
Make a quiz.
At the end of the course we
will distribute a quiz.
16. Evaluation:
- Evaluation sheet about group
performance:
It involves 1 minute at the end of
activity where the students write down answers on a ``1 minute paper'' to a few
questions as feedback to the instructor. The questions are as following:
·
Did
everyone in the group participate?
·
Did
the group stay on task?
·
Did
an individual dominate the group?
·
What
was the most important idea you learned today?
·
What
is one idea you are still confused about?
- Quiz:
At the end of the course students do this
5 minutes quiz which includes questions as following:
1) Give one example to electrify with impact,
friction and interference.
2) In the activity of bending water with a
straw, what was the reason that the pvc pipe draw the running water?
17. Teacher role:
- The
teacher reflects on the purpose and makes plans for inquiry learning. Teacher:
- Plans ways for each learner to be actively engaged in the learning process.
- Understands the necessary skills, knowledge, and habits of mind needed for inquiry learning.
- Understands and plans ways to encourage and enable the learner to take increasing responsibility for his learning.
- Insures that classroom learning is focused on relevant and applicable outcomes.
- Is prepared for unexpected questions or suggestions from the learner.
- Prepares the classroom environment with the necessary learning tools, materials, and resources for active involvement of the learner.
- The
teacher facilitates classroom learning.
· The teacher's daily, weekly, monthly, and
yearly facilitation plans focus on setting
content
learning in a conceptual framework. They also stress skill development and
model
and nurture the development of habits of mind.
- Teacher:
· Accepts that
teaching is also a learning process.
· Asks
questions, encouraging divergent thinking that leads to more questions.
· Values and
encourages responses and, when these responses convey misconceptions,
effectively
explores the causes and appropriately guides the learner.
· Is
constantly alert to learning obstacles and guides learners when necessary.
· Asks many
‘Why? How do you know? What is the evidence?’ type of questions.
· Makes
student assessment an ongoing part of the facilitation of the learning process.
18. Students’
role:
- Students view themselves as learners in the process of learning.
- They look forward to learning.
- They demonstrate a desire to learn more.
- They seek to collaborate and work cooperatively with teacher and peers.
- They are more confident in learning, demonstrate a willingness to modify ideas and take calculated risks, and display appropriate skepticism.
- Students accept an "invitation to learn" and willingly engage
in an exploration process.
- They exhibit curiosity and ponder observations.
- They move around, selecting and using the materials they need.
- They confer with classmates and teacher about observations and questions.
- They try out some of their own ideas.
-
Students raise questions, propose explanations, and use observations.
- They ask questions (verbally and through actions).
- They use questions that lead them to activities generating further questions or ideas.
- They observe critically, as opposed to casually looking or listening.
- They value and apply questions as an important part of learning.
- They make connections to previous ideas.
-
Students plan and carry out learning activities.
- They design ways to try out their ideas, not always expecting to be told what to do.
- They plan ways to verify, extend, confirm, or discard ideas.
- They carry out activities by: using materials, observing, evaluating, and recording information.
- They sort out information and decide what is important.
- They see detail, detect sequences and events, notice change, and detect differences and similarities.
-
Students communicate using a variety of methods.
- They express ideas in a variety of ways, including journals, drawing, reports, graphing, and so forth.
- They listen, speak, and write about learning activities with parents, teacher, and peers.
- They use the language of learning, apply the skills of processing information, and develop their own "ground rules" appropriate for the discipline.
-
Students critique their learning practices.
- They use indicators to assess their own work.
- They recognize and report their strengths and weaknesses.
- They reflect on their learning with their teacher and their peers.
19. Next lecture:
In our next lecture we will talk about charge
distribution of charged objects and electric force.
