This research aims to interpret Vygotsky’s theory in development of a child’s semiotic activity in first
grade mathematics classroom taught by open approach. This study focuses on investigate how first grade
students construct signs and symbols in solving addition problems with the help of psychological tools in
a mathematics classroom taught by open approach. The research was carried out in one first grade
mathematics classroom including 32 students aged 6 - 7 years old and an internship student who was
classroom teacher. Ethnographic methods were employed for collecting and analyzing data through
classroom observation with audio-video tape recordings on 17 consecutive lessons on addition, students’
written works, field note taking and interviewing the classroom teacher. The result showed that the learn-
ing and instructional materials and drawing schematic diagrams and students’ language use are psycho-
logical tools that play a crucial role in development of first grade students’ semiotic activity in solving
addition problems. Students used units blocks and base ten blocks to operate addition with two numbers
by decomposing and making ten strategies. Then, students drew schematic diagrams as symbol with their
words to represent how to add two numbers corresponds to the meaning and the strategies they used.

Vygotsky’s (1986, 1998) theory stipulates that the develop-
ment of the child’s higher mental processes depends on the
presence of mediating agents in the child’s interaction with the
environment. Vygotsky himself primary emphasized symbolic
tool-mediators appropriated by children in the context of par-
ticular sociocultural activities, the most important of which he
considered to be formal education (Kinard & Kozulin, 2008).
Cultural-historical development of human kind created a wide
range of higher order symbolic tools, including different signs,
symbols, writing, formulae, and graphic organizes. Individual
cognitive development and the progress in learning depend,
according to Vygotsky (1978), on the student’s mastery of
symbolic mediators and their appropriation and internalization
in the form of inner psychological tools. In Vygotsky’s cultural
historical theory cognitive development and learning are opera-
tionalized through the notion of psychological tools. Psycho-
logical tools first appear as external symbolic tools available in
a given culture (Kinard & Kozulin, 2008).
Vygotsky (1929: p. 145) described that the culture develop-
ment consists in mastering method of behavior which are based
on the use of signs as a means of accomplishing any particular
psychological operation. In this context culture has a special
meaning for Vygotsky. As van der Veer and Valsiner (1991)
mentioned, Vygotsky identified culture as sign systems-writing
systems, counting systems, and language. Such sign systems-
the key to a cultural-historical development of human behavior
are explained as psychological tools by Vygotsky. Psychologi-
cal tools are artificial instruments directed toward control over
human behavior and they are the products of historical devel-
opment of human behavior (Vygotsky, 1930/1997). Moreover,
psychological tools are differentiated from technical tools be-
cause the technical tools change the object but influence human
behavior or mind (Yoshida, 2006).
Based on Vygotsky’s cultural-historical perspective discus-
sion above, psychological tools play a crucial role in human
behavior and cognition by “transforming the natural human
abilities and skills into higher mental functions” (Vygotsky,
1986: p. xxv). Semiotic activity (van Oers, 2000) is one of
higher mental activity of inventing symbols and attributing
meanings explored by the children already from an early age.
van Oers (2000: p. 147) defined the term semiotic activity as
“the (inter or intra)mental activity of creating meanings and
signs, by reflecting on the interrelationships between (changes
in) signs and (changes in) their corresponding meanings, and of
adjusting signs and meanings accordingly”. Semiotic activity
(van Oers, 2000) in young children is one of mediated activity
focused on supporting student to get involve in mathematical
activity with the help of appropriated symbolic tool as psycho-

pline by drill and practice, without a proper understanding of
the relationship between sign/symbol and their meanings. The
children just memorized the formal mathematics sign/symbols
without the help of any mediating tool or psychological tool.
Although the discussion given above is important theoreti-
cally, it is more important to interpret the theory for enlighten
development of a child’s semiotic activity in a school context.
This research focuses investigation on how first grade students
construct signs and symbols in solving addition problems with
the help of psychological tools in a mathematics classroom
taught by open approach. In this study, the mathematics class-
room used for analyzed is the one of mathematics classroom
innovated by “Lesson Study and Open Approach” (Inprasitha,
2010) in Thailand. The open approach as a teaching approach
(Inprasitha, 2010) used in this research was incorporated in the
process of lesson study, the core professional development
process Japanese teachers use to continually improve the qual-
ity of the learning experiences they provide to their students
(Yoshida, 1999). In Thailand, Lesson Study and Open Ap-
proach is becoming an innovation for Thai teacher professional
development that help teacher recognize this aspects of stu-
dents’ mathematics learning. In this study, the researcher pre-
sents the analysis the psychological tools that help or has a
crucial role in development of first graders’ semiotic activity in
learning how to add two numbers from Vygotsky’s cultural-
The research was carried out in one first grade mathematics
classroom including 32 students aged 6 - 7 years old and an
internship student who was classroom teacher. The mathemat-
ics classroom was choose to be target group is the one of class-
room in Ban Nam Prae school, an elementary school in Chiang
Mai province, which participated in the “Project for mathemat-
ics teacher professional development innovated by lesson study
and open approach in northern educational service areas” since
2009 academic year. The project was conducted by Center for
research in mathematics education, Khon Kaen University and
the mathematics education program, faculty of education,
Chiang Mai University.
Data were collected during November-December in the sec-
ond semester of 2010 school year and consist of daily video-
taped recording of 17 consecutive lessons on addition in first
grade mathematics classroom made by two cameras. During in
each classroom teaching, one camera focused primary on inter-
action between teacher and student, especially in whole-class
discussion. The second camera focused on students’ group
working. Moreover, documentation consists of 17 lesson plans
on addition; students’ written works; daily field notes that
summarized classroom events and student ways of thinking;
and audio taped interview with the teacher. The data from the
video recording of each class was transcribed into protocol to
be used for video analysis and discourse analysis to analyze the
semiotic activity based on the cultural-historical perspective.
The analysis focused on the method by which student make
their own sign and symbols in solving addition problem with
the help of psychological tool.
From the analysis, in each lesson of the mathematics class-
room taught by Open Approach as a teaching approach has 4
steps as 1) posing open-ended problem situation 2) students’
self learning 3) whole discussion and comparison and 4) sum-
mary the lesson through connecting students’ ideas emerged in
the classroom. Three lesson (2/17, 4/17, 10/17) of a series of
seventeen addition lessons were choose to evidence the origin
and development of semiotic activity with the help of psycho-
logical tool. In the beginning of the lesson, the teacher typically
started with the presentation of the problem situation by telling
a story along with the real world objects and picture in an at-
tempt to motivate the student to learn about addition according
to the meaning of addition as “altogether” and “increasing”.
The task for first lesson, teacher ask student to express the ad-
dition sentence and think about how to add the two number (the
number of all children in play ground) in various way as fol-
lowings Figure 1.
Through this lesson, then children used units block and
base-ten blocks that teacher provided as thinking tool for solv-
ing the addition problem by decomposing and composing
strategy. Then, they drew picture and wrote up the process il-
lustrated their action in thinking about adding how to solve 9 +
4 as Figure 2.
The student reflected his thinking imagining using the num-
ber blocks and drew them up as shown above. The student took
out one single unit block and used arrow to transfer it to lining
of 9 blocks and finally showed the product of 10 to be com-
bined with the rest 3 blocks making the final product of 13. The
drawing was a psychological tool for developing semiotic ac-
tivity showing the thinking process using the blocks, which
served as the signifiers (meaning of addition) and the signified
(using the block in order to make ten).
Moreover, in the lesson 4/17 on the activity-Adding 8 + 3 I
can do it the students used the idea discussed in the previous
lesson in solving addition problem 8 + 3 from which the teacher

had taken the students’ idea accumulatively added up and con-
nected it with the thinking tools such as unit blocks and
base-ten block. The process further led to the development of
semiotic tool such as diagram which is the psychological tool
as suggested by van Oers (2000) reflected in the following pro-
tocol and the Figures 3(a), (b).
Ice: This one has only 8, not yet full. Find 2 more to fill it up.
Teacher: I see. Class, Ice told us that there were only 8
blocks. There were none here. Two are left out. Ice then took
two from there…
Ice: Yes, …to there.
Teacher: Oh, yes. Two are placed here making it…. (Turned
to other students)
Teacher: Making it ten. When we put two blocks here, (wrote
2 on the two blocks). Two and 8 (drew the line between number
8 and the 2 blocks and drew the arrow down) making it…
Teacher: Make it ten now (writing 10). Here, the remaining
Teacher: There is only one left (writing 1). And now ten and
Ice: Combined and become 11.
Teacher: Combined both to make… (writing + sign between
10 and 1.)
Students: Eleven (the teacher wrote equal sign followed by
From above protocol, it show how the teacher led student
into a semiotic activity in adjusting the sign (drawing with
block) invented by children in the previous lesson to more ab-
stract one as diagram. This process indicated that children’
semiotic activity has transformed through the process of inter-
nalization from mani p ulative tool to inner psychological tool.
In addition, through the lesson children were able to refine
the diagram by themselves. We can see that the process of cre-
ating and adjusting sign or in here the schematic diagram along
with the linking of the meaning through the use of arrows and
operation in each of the steps had been originated with the lan-
guage interaction between the teacher and the students in dis-
cussing and comparing done together in the classroom. In the
next lesson with more complex problem, we found that the
students used diagramming as the tool to solve addition prob-
lems and refined the diagram to represent the variety of think-
ing about how to make ten from decomposing the number dur-
ing the process of solving the addition problems easily and
skillfully. The teacher encouraged the students to communicate
their thinking with written explanation of their diagram as
shown in Figure 4.
Conclusion and Discussion
Based on Vygotsky’s theory, this research interprets the de-
velopment of a child’s semiotic activity in leaning to solve
addition problem in the classroom taught by open approach as

dents used units blocks and base-ten blocks to operate addition
with two numbers by decomposing and making ten strategies
and drew iconic sign according to the action of decomposing
number. Then, students drew schematic diagrams as symbol
with their words to represent how to add two numbers corre-
sponds to the meaning and the strategies they used. This finding
supports van Oers (2010)’s suggestions that young children
were able to reconstructed symbols according to their intentions,
gradually shifting to more abstract symbolizations. From the
analysis we found that, in promoting mathematical thinking like
semiotic activity in young children is culturally guided process,
wherein mathematical meaning can be assigned to action of the
From the interpretation, in conclusion, the development of a
child’s semiotic activity start out from the operating with ma-
nipulative materials into the children’s own schematic repre-
sentation and helping them to improve these representation for
the use of solving more complex problems, children are per-
sonally involved in the construction of psychological tools
(drawings, diagrams). Consequently, the research results con-
firm to van Oers (2010)’s mentions that the children learn to
carry out semiotic actions with the help of these psychological
tool as authenticated action of themselves. Moreover, devel-
oped semiotic activities of solving addition problem mediated
by schematic diagram with the use of language helped students
to learn a real concept of addition.
The results showed that the learning and instructional mate-
rials like unit blocks and base-ten block and drawing schematic
diagrams with students’ language use are psychological tools
that play a crucial role in development of first grade students’
semiotic activity in solving addition problems. In their deve-
lopment of semiotic activity in solving addition problems, stu-
