learning  process  of  students,  so  teachers  and 
parents can know children development from time 
to time. However, the success of a learning model 
depends  on  teaching  instruments  used  to  support 
the  learning  model.  The  instrument  is  something 
that  supports  the  implementation  of  learning, 
therefore  learning  instruments  must  be  in 
accordance with the learning model. In portfolio-
based  learning,  learning  instruments  are  needed 
such as manuals used by teachers in implementing 
learning, the role of students worksheets is used to 
test children's abilities and its results can be used 
as children's  portfolios, and daily  lesson plan  are 
used to support learning models in accordance with 
activity portfolio based. Based on the explanation 
above, the researcher wants to conduct research on 
the  development  of  portfolio-based  learning 
instruments in kindergarten. 
2  RESEARCH METHOD 
This  research  is  research  and  development/R&D 
method  because  researchers  want  to  develop 
portfolio-based  learning  instruments  for  early 
childhood  using  the  4D  development  model 
includes  four  stages  of  development  namely 
define,  design,  develop,  and  disseminate.  It  is 
expected  to  get  products  in  the  form  of  teacher 
guidebook,  students  worksheets, and  daily  lesson 
plans  for effective  activities.  It was  conducted  at 
PAUD  Terpadu  Alkhairat  Skep  in  Ternate  City. 
The  subjects  were  students  in  group  B  academic 
year 2018/2019, the reason is students were able to 
recognize letters, were able to read the beginning, 
were able to write and were able to understand the 
teacher's explanation. This research was conducted 
from  September  to  October  of  the  2018/2019 
school year. The instruments used in this study are: 
(1)  teacher  questionnaire  on  portfolio  learning 
devices  (2)  learning  implementation  observation 
sheet (3) validation results sheet. 
Data has been collected using these instruments 
will  then  be  analyzed  quantitatively  to  explain 
validity  and  effectiveness  and  the  practicality  of 
the  learning  devices  developed.  Data  obtained 
from  the  results  of  validation  by  experts  were 
analyzed  to  explain  the  validity  of  learning 
devices.  The results  of  the  trial  data,  namely  the 
teacher  questionnaire  and  student  performance 
value  data  are  used  for  the  effectiveness  of  the 
learning learning device.

Analysis to calculate the percentage of the 
number of teachers who responded to each category 
listed on the teacher's response questionnaire using 
the following formula: 
Pr= 
∑𝑅𝑠
∑𝑠
x 100% 
Then determine the category of implementation of 
each aspect or overall aspect of the implementation of 
the learning device (Nurdin, 2007): 
1.5   M   2.0 all implemented 
0.5  M   1.5 partly implemented 
0.0   M   0.5 not implemented 
3  RESULTS AND DISCUSSION 
Portfolio-based learning is student-centered learning 
that is very effective in teaching and learning. This is 
in  accordance  with  the  constructivism  theory 
according  to  Yager  (1992),  the  application  of 
constructivism  means  placing  students  in  a  central 
position in the overall learning. To support portfolio-
based learning, supporting instruments such as daily 
lesson plan do not include all portfolio and portfolio-
based  learning  scenario  stages  so  that  daily  lesson 
plan are needed, then improper portfolio compilation 
and  making  portfolios  are  only  a  collection  of 
students assignments that only cognitive and motoric 
development can be  seen while  in the  portfolio all 
that is included or all aspects of development are in, 
that is why photos and videos are needed to find out 
the extent of language development, gross motoric, 
art  and  several  other  developments,  in  accordance 
with  previous  research  deal  with  portfolio-based 
learning  showed  that  portfolios  contain  work  and 
activities  of  children  in  learning  process  so  that 
teachers and parents can see child development, this 
is in accordance with Herman's theory, Gearhart and 
Ascbacher (1995) states that the use of portfolios in 
learning has two functions, that are used as a form of 
learning assessment as well as learning techniques. 
Furthermore  winter  (1989)  also  emphasizes  the 
use  of  a  good  portfolio  must  contain  a  number  of 
learning  experiences  and  should  also  be  supported 
by documentation. Therefore it takes preparation and 
assessment  handbook  that  summarizes  how  the 
portfolio and preparation of portfolio as well as ways 
to assess the portfolio. The process of developments 
instruments  done  through  some  stages  such  as 
define, design and develop and disseminate aims to 
produce  learning  instrument  in  this  case  teacher 
handbook,  students  worksheet,  and  daily  teaching
