Introduction
                                Educational psychology informs teachers’ perspectives by providing them with evidence- based theories, research findings, and strategies that can enhance their teaching practices. By understanding the principles of educational psychology, teachers can make informed decisions about instructional methods, classroom management techniques, and assessment strategies that are more likely to promote effective learning and development in their students [1]. Teachers’ perspectives influence educational psychology by providing valuable input and feedback to researchers and theorists. Through their experiences in the classroom, teachers can offer insights into the practical implications of educational psychology theories, highlighting what works well and identifying areas that may require further investigation. Their perspectives can contribute to the refinement and development of educational psychology as a field, making it more relevant and applicable to the real-world context of teaching and learning [2].
In program research and program reform, the theoretical basis for changing the general education program is always a “hot issue”. The transformation of the general education program is crucial to meet the demands of a rapidly changing job market and prepare students for the challenges of the 21st century. It requires a multidisciplinary approach that incorporates innovative teaching strategies and technologies. The birth and development of constructivist theory is called a “revolution in current educational psychology” because it has had a tremendous impact on the theory and practice of teaching and education in many nations throughout the world, especially the reform of the general education program [3]. The theory emphasizes the importance of individual differences and the need to tailor teaching methods to meet the unique needs of each student, which has led to a more personalized approach to education. Additionally, it has encouraged the use of technology in the classroom as a means of enhancing learning and engagement. The constructivist program emphasizes the importance of nurturing pupils’ creativity, sense of teamwork, and problem-solving skills. This approach has proven effective in preparing students for the demands of the modern workforce, where collaboration and innovation are highly valued. Furthermore, it has been found to promote long-term retention of knowledge and a deeper understanding of concepts. This theory challenges traditional teaching methods by promoting active learning and student-centered approaches. It encourages teachers to facilitate learning rather than simply imparting knowledge to students. The attention of educators has been drawn to this since it conforms to contemporary standards.
According to Piaget’s theory of cognitive development, schooling should enable both men and women to innovate through creativity, invention, and discovery [4,5]. Piaget believed that education should not only focus on imparting knowledge but also on developing critical thinking skills and problem-solving abilities in individuals, which would allow them to become active and productive members of society. This approach to education would foster creativity and innovation, enabling individuals to make significant contributions to their communities. Yet, as learning is a self-directed, individual activity in which students seek their own experiences, constructivism knowledge is necessary for teaching and learning. Constructivism knowledge emphasizes the importance of active learning, where students are encouraged to explore and discover new concepts on their own. This approach allows for a deeper understanding of the material and helps students develop critical thinking skills. Two theories, notably Piaget’s cognitive constructivist theory of learning and Vygotsky’s theory of social construction, provided the foundation for this study. Piaget’s theory emphasizes the importance of individual exploration and discovery, while Vygotsky’s theory highlights the role of social interaction in learning [6]. By combining these two theories, this study aims to explore how both individual and social factors contribute to students’ understanding and critical thinking skills. It is vital to maintain a full understanding of all system components to be studied in relation to the core principles of student learning. Piaget’s theory emphasizes the importance of individual cognitive development, while Vygotsky’s theory highlights the role of social interaction and cultural context in learning. Therefore, this study aims to explore how these two theories can be applied to understand student learning in a comprehensive manner. The theories of cognitive and social education concur that students generate or construct meaning from their experiences [7]. Furthermore, cognitive theory emphasizes the importance of individual mental processes in learning, while social education theory highlights the role of social interactions and cultural context in shaping learning experiences. By combining these two theories, a more holistic understanding of student learning can be achieved. Thus, Piaget’s and Vygotsky’s theories of learning assist this study’s efforts to guide and construct appropriate learning activities that enhance science processing abilities. Piaget’s theory emphasizes the importance of individual exploration and discovery, while Vygotsky’s theory emphasizes the role of social interaction and collaboration in learning. Therefore, incorporating both theories can provide a comprehensive approach to designing effective science learning activities that cater to different learning styles. The active engagement of a child with his environment, according to Piaget’s theory of intellectual development, is what generates cognitive development. Vygotsky’s sociocultural theory, on the other hand, emphasizes the role of social interaction and cultural context in shaping a child’s cognitive development. This study aims to integrate both theories to design effective science learning activities that take into account both individual and social factors.
Students should not only be passive recipients of instruction; they should actively engage in their education. This means that students should participate in class discussions, ask questions, and take an active role in their own learning process. By doing so, they will not only gain a deeper understanding of the material but also develop critical thinking skills that will serve them well in the future. Active engagement from the youngster may take the form of physical manipulations, visual observations, or internal or mental movement or transformation. The teacher offers background knowledge, but it is the student’s responsibility to investigate a specific occurrence, discover pertinent material, quantify it, produce a hypothesis, and then verify their investigation’s interpretation and predictions by deducing or inducing. This approach to learning is known as inquiry-based learning, which encourages students to take an active role in their education and develop critical thinking skills [8]. Inquirybased learning also helps students to retain information better as they are actively engaged in the learning process, rather than just passively receiving information from the teacher [9,10]. It also prepares them for real-world problem-solving situations where they need to investigate and analyze information to make informed decisions. By engaging in this process, students are able to gain a deeper understanding of the subject matter and develop a sense of ownership over their own learning. It is also considered that interaction between students and teachers facilitates learning, improves communication, and promotes the exchange of ideas. Furthermore, students who are actively involved in the learning process are more likely to retain information and apply it in real-life situations. This approach to education also fosters critical thinking skills and encourages students to become lifelong learners. According to Vygotsky’s, cognitive growth is greatly impacted by other individuals and environmental factors. Vygotsky’s sociocultural theory emphasizes the importance of social interaction in cognitive development, suggesting that learning occurs through collaborative activities and communication with others. Therefore, creating a positive and interactive classroom environment can enhance students’ cognitive growth and academic achievement. Constructivist theory holds that individuals must first construct, comprehend, and remember what they have learnt (cognitive processing of information), then practice and apply their new skills and knowledge to make it more natural, efficient, and a permanent part of their practice (behavioral) [11,12]. Therefore, social interaction and collaboration with others play a crucial role in the learning process as they provide opportunities for individuals to construct knowledge together, receive feedback, and engage in discussions that promote critical thinking and problem-solving skills. Constructivist approaches also emphasize the importance of creating a supportive learning environment that encourages exploration, experimentation, and reflection.
If either of these processes is lacking, learning will fail. The two processes that are crucial for successful learning are attention and motivation. Without attention, the learner will not be able to focus on the material being presented, and without motivation, the learner will not have the drive to engage with the material. Theorists attempted to explain how students learned, emphasizing the significance of condition selection and mental growth. These theories led to the development of various teaching strategies that take into account the learner’s attention and motivation, such as active learning, problem-based learning, and inquiry-based learning. These approaches aim to create a more engaging and interactive learning environment that promotes deep understanding and long-term retention of knowledge. It is challenging to conclude that all learning is founded on a certain idea. Instead, learning is a complex process that involves various factors such as prior knowledge, motivation, and environment. Therefore, it is essential to consider multiple perspectives when studying the learning process. For teachers to have constructivist lessons, Powell and Kalina claimed that cognitive and social constructivism must be utilized [13]. Cognitive constructivism emphasizes the individual’s active role in constructing knowledge, while social constructivism highlights the importance of collaboration and interaction with others in the learning process. Therefore, teachers should integrate both approaches to create a comprehensive and effective learning experience for their students. It is believed that no one hypothesis adequately explains learning. By combining both approaches, teachers can address the strengths and weaknesses of each theory and tailor their teaching methods to meet the diverse needs of their students. This approach can help students develop a deeper understanding of the subject matter and improve their overall academic performance.
Currently, Vietnam is in an important period of program reform, so it is necessary to attach importance to the role of program theory, systematically study program theory (including constructivist theory), facilitate a comprehensive and systematic view, and create the ability to evaluate and choose good and positive experiences from around the world, and avoid one-sided, conservative, dogmatic approaches. By incorporating constructivist theory into their teaching methods, educators in Vietnam can create a more dynamic and interactive learning environment that promotes critical thinking and problem-solving skills. This approach can also help students develop a deeper understanding of the subject matter and better retain information. Furthermore, constructivist theory encourages students to take an active role in their own learning, which can lead to increased motivation and engagement in the classroom. Ultimately, this can lead to better academic outcomes and prepare students for success in their future careers.
Prior to now, there has been a dearth of studies on primary teachers in Vietnam, particularly the designing of teaching methods and forms through experiential activities using the constructivist theory of primary teachers. This research aims to fill this gap by investigating the effectiveness of using constructivist theory in designing teaching methods and forms through experiential activities for primary teachers in Vietnam. The findings of this study could potentially contribute to the improvement of primary education in Vietnam. In order to fill this void, this study evaluates which experiential activities primary teachers are designing by using constructivist theory and following an intervention: the research findings will provide a solid scientific foundation for evaluating the current state of designing experiential activities in the topic according to constructivist theory in elementary schools and suggesting a suitable course design approach for elementary school students. The results of this study could also inform teacher training programs and professional development opportunities to better equip primary teachers with the skills and knowledge needed to design effective experiential activities for their students. Additionally, the findings may have broader implications for education systems in other countries that are seeking to incorporate constructivist theory into their primary education curriculum.
The inquiry commences with a literature review on designing the experiential activity by using constructivist theory of primary teachers. The second section provides a foundational framework for analysis, including the study’s methodology, results, and discussion. The conclusion is contained in the final section.

Table 1 shows that the teachers participating in
  the survey have a bachelor’s degree or higher, the
  highest professional qualification of teachers is a
  master’s degree. The teachers are mainly qualified
  from university of pedagogy (62.8%), college of
  pedagogy (30.9%), pedagogical practice (4.2%),
  and graduate school (2.1%). Teachers’ teaching
  experience ranges from 1 year to 35 years, with a
  mean of 10.69 years. In which, 41.4% of teachers
  work in places with difficult facilities and socio-
  economic conditions, 58.6% of teachers working
  at schools with favorable facilities and socio-
  economic conditions. Thus, the majority of teachers
  participating in the survey have professional
  qualifications that meet and exceed standards,
  most teachers have less than 10 years of teaching
  experience. The number of teachers participating
  in the survey working in a place with favorable
  facilities and socio-economic conditions is more
  than the number of teachers working in a place
  with favorable facilities and economic conditions-
  difficult society. From April 2021 to April 2022,
  an entire year was devoted to the collection of
  data. Participants were given informed consent,
  and anonymity and confidentiality rules were
  conveyed to them; the information sheet outlined
  their obligations and right to withdraw from the
  study.
Instrument
The author collects information on the practice of designing experiential activities in a constructivist
  primary school subject by using questionnaire
  survey methods, conducted using a teacher’s
  questionnaire of primary schools in 6 provinces:
  Hanoi, Vinh Phuc, Ninh Binh, Cao Bang,
  Bac Giang, and Lao Cai. The questionnaire is
  designed and collected through Google Form.
  The questionnaires were sent to teachers to collect
  information, the total number of questionnaires
  collected was 543 with complete answers.
  Each questionnaire consists of two parts: the
  information part of the survey respondents and
  the answer to the survey questions. The survey
  questions include:
1. Survey of primary school teachers’ perceptions
  of experiential learning is done through
  a questionnaire including the characteristics
  of experiential learning and non-experiential
  learning characteristics with answers. are
  choices divided by Likert scale with 3 levels:
  disagree, agree, strongly agree and are scored
  from 1 to 3, respectively;
2. Survey the design of experiential activities
  in the subject with questions about criteria,
  bases, design process, methods and forms
  of teaching with options divided on a Likert
  scale of 5 levels: never, rarely, occasionally,
  often, very often, and are scored from 1 to 5,
  respectively.
Values on the Likert scale are divided into 3 or 5
  equal parts and distribute each part corresponding
  to a measure value: there are 3 levels: Distance
  value=(Maximum-Minimum)/3=(3-1)/3=0.66. Authors define the value fragments: 1.00-1.66
  (rounded to 1): Disagree; 1.67-2.33 (rounded to 2):
  Agree; 2.34-3.00 (rounded to 3): Strongly agree.
  For the Likert scale, there are 5 levels: Distance
  value=(Maximum-Minimum)/5=(5-1)/5=0.80. The authors also define the value fragments:
  1.00-1.80 (rounded to 1): Never; 1.81-2.60
  (rounded to 2): Rarely; 2.61-3.40 (rounded to 3):
  Occasionally; 3.41-4.20 (rounded to 4): Regular;
  4.21-5.00 (rounded to 5): Very often. The author
  determines the value segments as above because
  the value segments are divided equally, creating a
  balance between each evaluation level.
                                                                Results
                                Teaching methods, teaching forms to organize
  experiential activities in the subject according to
  constructivism theory
When designing and organizing experiential
  activities in the subject according to constructivist
  theory, primary teachers also often use a variety of
  teaching methods and different teaching methods.
  According to the survey results in Table 2, the
  teaching methods and teaching forms used most
  often by teachers are: Observation (M=4.26;
  SD=0.603), Conversation (M=4.13; SD=0.637),
  Discussion (M=4.18; SD=0.568), Practice
  (M=4.18; SD=0.612), Problem-stating and
  Problem-solving (M=4.07; SD=0.603), Games
  (M=4.09; SD=0.597) (Table 2).

There is a difference between teachers in the
  two groups when using teaching methods and
  teaching forms: Observation, Conversation,
  Discussion, Practice, Experiment, Explanation,
  Problem-stating and Problem-solving, Project, Hand making dough, Games when designing
  experiential activities in the subject according to
  constructivist theory (the Sig index of the F-test of
  these teaching methods and teaching forms are all
  less than 0.05).
Groups of teachers who are working in schools
  with difficult facilities and socio-economic conditions
  often use these teaching methods and
  teaching forms less often than teachers working
  in schools with favorable facilities and socio-economic
  conditions, the mean score of these teaching
  methods and teaching forms in the group of teachers
  working in schools with difficult facilities and
  socio-economic conditions is often higher than the
  mean score of teachers working in schools with favorable
  facilities and socio-economic conditions.
  Results of a one-way Analysis of Variance (ANOVA) test on the difference in selection between primary
  teachers with different teaching experience,
  showed that there is no difference between teachers
  in groups of seniority when choosing ideas
  (p>0.05). Thus, primary school teachers often
  use traditional and popular methods and forms of
  teaching to organize experiential activities in the
  subject according to constructivist theory. Modern
  teaching methods, teaching forms: projects, hands
  on dough, plays, clubs, etc., are used less often by
  teachers.
 The results of the independent samples test to
  examine the differences in the use of teaching methods and teaching forms in the design of
  experiential activities in the subject according to
  constructivist theory are shown in Table 3 and Table 4.

  forms: Storytelling, Investigation, Role-playing,
  Sightseeing, Contest, Drama, Club (Sig index of

The process of designing experiential activities in
  the subject according to constructivist theory
When teachers were asked about the process
  of designing experiential activities in primary
  school subjects according to constructivist theory
  with the question “When designing experiential
  activities in the subject, what do you usually do?”
  with 5 levels of opinion: 1-Never: This should not
  be done when designing any experiential activity;
  2-Rarely: This is done when the design is less than
  25% of the experience; 3-Occasionally: This is
  done when designing about 25% less than 50%
  of the experience; 4-Regularly: This is done when
  designing about 50%-75% of experience activities;
  5-Very often: This is done when designing more
  than 75% of the experience activities, the results
  are shown in Table 5.

It can be seen from Table 5 that teachers regularly
  perform the following tasks: “Identifying lessons
  or activities in the lesson that can be used for
  experiential activities” (M=4.10, SD=0.572);
  “Identifying the purpose of experience activities”
  (M=4.07, SD=0.592); “Finding out the needs,
  current capacity/existing knowledge of students”
  (M=3.99, SD=0.562); “Identifying the means of
  supporting the activity/experience environment”
  (M=3.98; SD=0.571); “Building experience
  situations” (M=3.98, SD=0.605); “Building an
  experience implementation guide” (M=3.96;
  SD=0.591); “Identifying the form of experience”
  (M=3.97; SD=0.566); “Developing methods
  and tools to evaluate experience activities”
  (M=3.96; SD=0.562) when designing experiential
  activities in primary school subjects according
  to constructivist theory. Results of one-way
  ANOVA test on the difference in choice between
  groups of primary teachers with different teaching
  experience when implementing the steps of
  designing experiential activities in the subject
  according to constructivist theory, show that
  there is a difference between groups of teachers
  with different seniority when choosing opinions
  (p>0.005). Teachers regularly take steps to design
  experiential activities in the subject according to
  the proposed constructivist theory.
                                                                Discussion
                                According to the constructivist theory, the purpose of this study was to analyze the process of organizing
  and designing experiential activities in the
  subject by primary school teachers. The constructivist
  theory posits that learners construct knowledge
  based on their experiences and interactions
  with the environment. Therefore, analyzing the
  process of organizing and designing experiential
  activities in the subject by primary school teachers
  can help improve students’ learning outcomes.
  Using the given data, the investigation led to the
  following conclusions:
1. Story-telling and conversation were the most
  chosen of teaching methods and instructional
  forms in the creation of experiential activities
  in the subject based on constructivist theory;
  and
2. Experiential activity in the subject based on
  constructivist theory was the most chosen of
  primary teachers.
The first field was the use of teaching methods and
  instructional forms in the creation of experiential
  activities in the subject based on constructivist
  theory. Observation was the most teaching
  method which primary teachers used the most
  to develop the experiential activity in the subject
  according to constructivist theory. The following
  were conversation and storytelling. And the last
  teaching method was club. In the academic life of
  any student, all subjects are regarded to be main
  subjects. The club method involves extracurricular
  activities that complement the academic
  curriculum and provide opportunities for students
  to explore their interests and develop new skills.
  Therefore, it is important for students to balance
  their academic and extracurricular pursuits to
  achieve a well-rounded education. When students
  move from one cycle to the next, they experience
  reversibility and commitment. Presently, there
  is a need to assist students with this transition,
  which is related to constructivist theory. Educators
  attempt to implement the most effective method of
  instruction, regardless of the subject matter being
  taught or learned, in order to improve student
  learning. To assist children in acquiring higher-
  order thinking skills, both teachers and students
  participate in the learning process. Teachers’ understanding of many teaching styles enables
  them to employ a variety of methods when
  developing lesson plans, which promotes higher
  order thinking. Acting and exchanging through
  conversation or story-telling is also one of the
  proactive ways in a student-centered classroom that will help maximize the learners’ related
  skills. In a constructivist classroom, learners
  acquire new knowledge and concepts through a
  variety of learning activities, and it is the teachers’
  responsibility to encourage such classrooms.
  In addition, Hussain noted that, according to
  Vygotsky’s social constructivism, effective
  learning may be achieved through group work
  and social interaction in order to learn new things
  and ideas and enhance intellectual development
  [14]. In other words, the constructivist approach
  emphasizes the importance of active participation
  and collaboration among learners, as well as the
  role of the teacher in facilitating and guiding the
  learning process. This approach also recognizes
  that knowledge is not simply transmitted from
  teacher to student, but rather constructed by
  learners through their own experiences and
  interactions with others. Learning through
  conversation and story-telling is also one of the
  ways to improve learners’ language ability. As
  according to Hajal, language is a very useful factor
  for students to utilize when learning a new notion;
  the zone of proximal development is where the
  learner develops new information based on their
  existing knowledge [15]. Therefore, incorporating
  conversation and story-telling in language learning
  can help learners to bridge the gap between their
  current knowledge and the new information
  they need to acquire, leading to a more effective
  learning experience. Additionally, these methods
  can also enhance learners’ communication skills
  and cultural understanding.
The second field was the process of developing
  experiential activities in the subject based on
  constructivist theory. While choosing opinions of
  developing experiential activities in the subject
  based on constructivist theory, there is a difference
  between groups of teachers with varying levels
  of experience. In accordance with the proposed
  constructivist theory, educators regularly design
  experiential activities in the field of study, the most
  chosen option was identifying lessons or activities
  in the lesson that can be used for experiential
  activities. This indicates that teachers with more
  experience may have a better understanding of
  how to incorporate experiential activities into
  their lessons, while those with less experience
  may need more guidance and support in this
  area. Additionally, it highlights the importance of
  providing professional development opportunities
  for all teachers to enhance their ability to design
  and implement experiential activities. For
  education, experiential learning is one of the newest but most effective approaches in the
  new era, especially in the constructivist subject
  design of subjects with experiential activities.
  Constructivist learning theory is consistent with
  experiential activity in that the consequences of
  the learning process are variable and frequently
  unpredictable, and learners take a significant part
  in evaluating their own learning. For instance,
  how one student chooses to handle an issue and
  what one student infers from experience will
  differ from that of another student [16]. According
  to Lewis and Williams, the simplest definition of
  experiential learning is learning from experience
  or learning by doing [17]. Experiential learning
  allows students to actively engage in the learning
  process and apply their knowledge to real-world
  situations, leading to a deeper understanding
  and retention of the material. This approach also
  promotes critical thinking, problem-solving skills,
  and collaboration among students. In order to
  build new abilities, new attitudes, or new ways
  of thinking, experiential education first immerses
  adult learners in an experience and then invites
  reflection on the encounter. Experiential learning
  encompasses all modes of learning despite its oftenoverlooked
  value. Active engagement involving
  the full person, including his ideas, emotions,
  and physical action, is one of its fundamental
  principles. In addition, they state that experiential
  learning can take numerous forms, including
  leisure activities, travel, experiences, cooperative
  learning, and play [18-21]. Experiential learning
  is a holistic approach that encourages learners to
  actively participate in their own learning process,
  leading to deeper understanding and long-term
  retention of knowledge. This approach has been
  shown to be effective across a wide range of
  subjects and age groups, making it a valuable tool
  for educators at all levels. In this regard, Enright
  believes that people must learn from experience
  in order to survive and that they possess a highly
  developed aptitude for doing so [22]. He concluded
  that as people mature, their experiences alter their
  learning process, and that their motivation to learn,
  their field of study, and their learning style are all
  affected by the educational process.
                                                                Conclusion
                                The design of experiential activities in the subject,
  according to the constructivist theory of the
  teacher, is aimed at the learners and based on the
  objectives and content of the lesson or learning
  activities. The teacher should create opportunities
  for learners to construct their own knowledge educathrough
  hands-on experiences, problem-solving,
  and collaboration. This approach can enhance
  students’ motivation, engagement, and retention
  of the subject matter. The constructivist theory
  emphasizes that learners actively construct their
  own knowledge and understanding through their
  experiences. Therefore, the design of experiential
  activities should provide opportunities for
  learners to engage in meaningful and authentic
  tasks that promote active learning and reflection.
  The design steps ensure the requirements and
  characteristics of experiential activities according
  to constructivist theory but have not yet brought
  about high efficiency. Therefore, in order to
  improve the effectiveness of the design of
  experiential activities in primary school subjects
  according to constructivist theory, teachers need
  to fully and correctly perceive the characteristics
  of experiential activities in subjects based on
  constructivist theory. This can be achieved
  through continuous professional development
  and training programs for teachers to enhance
  their understanding and implementation of
  constructivist theory in designing experiential
  activities. Additionally, collaboration among
  teachers and the sharing of best practices can
  also contribute to improving the effectiveness of
  experiential activities in primary school subjects.
  When teachers design well-designed experiential
  activities in primary school subjects according
  to constructivist theory, they will significantly
  contribute to the development of quality and
  capacity for students at this foundation level.
