Teaching  Philosophy  Statement  

Module  1  –  Course  Design  

•  Title:  Basic  Electrical  Engineering  (L  –  T  –  P:  4  –  0  –  0)    •  Level:  First  year,  semester  2    •  Changes   that   were   made   based   on   theory   and   practices   learned   during   the  

course  –  Student  information  card  –  OfTice  hour  –  Technology  Incorporation    –  Active  and  collaborative  learning  was  introduced  –  Problem  Based  Learning  –  Flipped  classroom  –  Implementation  of  learning's  from  Richard  Felder’s  paper  

•  Changes  to  be  made  –  Include  course  description  document  –  Implement  learning  from  the  ‘Tirst  day  of  class’  assignment  

 •  Strategies  used  to  connect  with  the  students  

–  Student  information  card  •  Emails  •  Whatsapp  

–  Giving  assignments  to  students  which  required  my  guidance  –  Edmodo  

 

Module  –  2  Active  Learning  Activity  1:  Think  –  Pair  –  Share        Class  topic  /  subtopic  

Activity   SpeciCic  question  asked   Details  of  implementation  

Time  allotted  

Actuators   Think  –  Pair  –  Share  

List   the   various   actuators  available  which  produce  the  motion  or  action  required  in  a  mechatronic  system  

Team  of  2      Reporter   has   the  highest   roll   number  in  the  team  of  2    

Each   student   of   the  team   spends   time   on  thinking   and   writing  the  response    

The   students   then  turn  to  their  partners  a nd   s h a r e   t h e i r  response    

Each  team  shares  two  different   actuators  with  class  

2  min  list                                1  min  share  

ReClections:    Activity  1:  Think  –  Pair  –  Share    

•  I   took  a   feedback  after   the  activity.   I   received  a  good  response   for   this  activity  from  my  students,  they  all  liked  it.    

 •  The  students  said  at  the  end  of  this  activity  they  got  to  know  many  actuators  that  

are  used  in  a  mechatronic  system.    

•  I  had  to  use  the  overhead  projector  for  this  activity  and  the  remote  that  is  used  to  switch  on  the  projector  was  taken  by  some  other  faculty.  

 •  I  will  have  to  work  on  how  to  control  the  class  and  I  Tind  it  little  difTicult  to  get  

my  students  attention  back  after  the  activity.  

•  I  will  conduct  the  same  activity  in  the  next  semester  with  slight  modiTication  in  the  question.  

•  The  time  taken  to  complete  this  activity  exceeded  the  allocated  time.  

Activity  2:  Send/Pass  –  a  –  Problem  

  Class  topic  /  subtopic  

Activity   Question  that  was  asked  

Details  of  implementation   Time  allotted  

Applications  of  DC  Motors  

Send/Pass  –  a  –  Problem  

Which  DC  motor  can  be   used   f o r   an  appl icat ion   that  demands  •  Constant   speed  

and   not   very  high   start ing  torque  

•  Variable   speed  and   very   high  starting  torque  

Team  of  4  (and  four  teams  form  one  major  team)    Recorder  is  the  tallest  in  the  team    

Team  1  records  their  ideas  and  place  it  in  the  envelope    

Team  2  also   records   their   ideas  and  place  it  in  the  envelope  

Similarly   Team   3   also   records   their  ideas  and  place  it  in  the  envelope  

Team   4   looks   at   the   suggestions  provided   by   the   3   teams,   adds   its  own   and   then   synthesizes   the   ideas  from  all  the  four  teams    

Teams  select  the    two  best  solutions  and  share  it  with  the  class

ReClections:    Activity  2:  Send/Pass  –  a  –  Problem    •  I  conducted  a  feedback  after  this  activity.  As  this  activity  is  a  little  different  

from  the  other  activities  I  conduct,  my  students  were  very  excited  about  this  activity  and  they  enjoyed  it.    

•  There  was  some  problem  with  the  cable  connection  of   the  projector  which  wasted  my  time  in  Tixing  the  problem.    

•  I  had  to  remind  them  to  place  their  answers  in  the  envelope  and  pass.  There  was  lot  of  noise  in  the  class  

 •  I  will  conduct  this  activity  in  the  next  semester  as  well.  

 

Module  –  3  Collaborative  Activity  

 Student  –  Team  –  Achievement  –  Divisions  (STAD)  activity    

 The  objectives  of  this  activity  are:  

•  Better  understanding  of  the  concepts  

•  Revision  of  important  concepts  

•  Gain  mastery  over  the  concepts  

•  Students  will  learn  to  work  in  teams  

•  Increase  students  involvement  in  class  

•  Learn  by  helping  the  teammates  

ReClections:    •  In  order  to  maintain  the  objective  of  the  activity,  I  had  to  keep  on  reminding  

my  students.  

•  Maintaining   the   time   limit   for  each  bit   (60  minutes   time  of   the  class   that   I  have  divided  in  bits)  was  a  challenge.  

 •  Keeping  all  students  involved  in  the  class  was  difTicult.  

•  Keep  the  discussion  going  amongst  the  team  members    •  Keep  the  collaboration  from  wandering  from  objectives  

•  Motivate  non  participating  members  

•  Class  attendance  

Module  –  4  Technology  Incorporated  For  the  current  semester    •  I  used  an  app  called  ‘Edmodo’  which  is  freely  available.  

•  I  created  a  group  which  has  all  my  students  as  group  members  in  this  app.  

•  Students  can  access  this  app  through  their  mobile  phones  or  tablets.  

•  I  make  all  the  announcements  or  any  notiTications  on  this  app.  

•  All  the  assignment  questions  will  be  displayed  on  this  app.  

•  I  share  all  my  lecture  notes,  text  books  and  all  the  material  related  to  the  course  on  this  app  

•  I  conduct  multiple  choice  quizzes,  true  or  false  quiz  through  this  app  in  the  class  

 For  next  semester    •  I  will  be  using  the  same  app  but  in  addition  to  the  things  that  I  am  following  in  

this  semester,  I  will  record  micro  lectures  and  share  it  with  them  through  the  app  so  that  they  can  refer  it  anytime  when  they  need  it.  

 •  I  will  also  upload  some   lectures   from  NPTEL  related   to   the  course  which  will  

help  my  students  understand  the  concepts  better.      •  I  am  also  planning  to  upload  few  animations  (videos)  relating  the  concepts  of  

the  course  which  will  enhance  students  learning.      •  I  am  planning  to  conduct   Tlip  classroom  sessions  as  possible,  so  that   the  class  

time  can  be  effectively  used  to  strengthen  their  problem  solving  skills.
