Cognitive Constructivist Way of Teaching Scientific and Technical Contents

For pupils to obtain high-quality and permanent knowledge, it is important that the teaching of scientific and technical contents is based on cognitive constructivist approach. We carried out a research, during which we asked three research questions, on a sample of 167 class teachers in the Republic of Slovenia. We wanted to find out: how often class teachers included elements typical of cognitive constructivist approach; was the frequency of using elements of cognitive constructivist teaching model linked to the teacher’s concern for their own professional development, and was the frequency of using elements of cognitive constructivist teaching model linked to the factors, such as the teacher’s estimated importance, difficulty and necessity of Science and Technics, the assessment of their own competence and professional enthusiasm. Data were collected with three scales: ways of teaching scientific and technical contents; attitude to scientific and technical contents and teaching and components of professional development. Data were processed according to descriptive and inferential statistics. The research showed that the formulation and verification of hypotheses, two important elements in view of cognitive constructivist teaching model, were less often represented. With statistically significant higher frequency they were organized by teachers, who rated their competence higher, were more enthusiastic and cared more about their professional development.


Introduction
In today's highly developed technological world, in the time of fast and unpredictable technological changes, a relevant technological competence is of fundamental importance for people. Social and economic changes challenge expert consideration on the importance of technology and the ways of education that will, along the entire vertical of national school systems: from pre-school to post-graduate education, enable its achievement. It is important to achieve technological literacy in each individual. Johnson (1989) defines Technology as "the application of knowledge, tools, and skills to solve practical problems and extend human capabilities" (p.13), and states that it is enhanced by the discoveries of science and shaped by the designs of engineering. When defining technology, various researchers (McRobbie, Ginns, and Stein, 2000;Gardner, Penna, and Brass, 1996;Johnson, 1989;Jones and Carr, 1992) point out the following: a) technology is a process; b) it has a human dimension; c) technology is situated (it is conducted within contexts and constraints); d) it includes a social dimension; and (e) it leads to the development of products or artefacts.
For quality teaching of contents related to natural sciences and technology it is essential for teachers to have in-depth knowledge of technology that encompasses all of the five dimensions; while also their conceptions are important.
Research has shown that teachers' beliefs are a strong determinant of teachers' behaviour. Teachers' perceptions of subject discipline and their conceptions of teacher and student role have an important impact on the teachers' decision-making and teaching (Šteh Kure, 1999;Valenčič Zuljan, 2007;Tigchelaar, Brouwer, and Vermunt, 2010). For example, a teacher who saw himself as the guardian of conventional wisdom in science adopted a transmission model of teaching in the classroom and talked about imparting a desired amount of knowledge (McRobbie and Tobin, 1995, as cited in McRobbie, Ginns,

Cognitive constructivist way of teaching scientific and technical contents, International Journal of Cognitive Research in Science, Engineering and Education (IJCRSEE),9(1),[23][24][25][26][27][28][29][30][31][32][33][34][35][36] combination of grasping and transforming experience' (Kolb, 1984, p. 41). "This process is portrayed as an idealized learning cycle or spiral where the learner 'touches all the bases' -experiencing, reflecting, thinking, and acting" (Kolb and Kolb, 2009, p. 44). Various studies on the effects of experientially oriented learning in Science and Technics were carried out at various levels of schooling (Abdulwahed and Nagy, 2009;Dzan et al., 2015;Crompton, 2020;Cotič et al., 2020). Cotič et al. (2020) examined the effect of an experiential learning model (The Mobile Natural Science Learning -MNSL) on the knowledge of 4th grade primary school students in Slovenia, during natural science school lessons at the seashore through the use of tablets. Mobile technology provides authentic learning, assisting outdoor lessons providing material and environmental context in learning, which support the experience of a learner. Findings indicate that the MNSL-model had a positive effect on students' achievement in science, more precisely in knowledge on marine organisms and life at the seashore.
Several researchers studied the impact of instructional methods on students' attitudes toward technology and knowledge (Boser, Palmer, and Daugherty, 1998;Lin et al., 2020). In further text we refer to the examples of studies that in various ways emphasize the importance of connecting various didactic strategies and learning methods.
For the development of scientific and technological literacy it is crucial that learners (children and young people) get familiar with basic scientific and technical conceptions, support them with facts and connect them in a network of knowledge.
In teaching, the explanation method significantly contributes to the clarity and systematic nature of basic conceptions and rules, and the conversation and discussion methods of teaching help verify student's understanding, putting the contents in different perspectives, opening unsolved questions (Valenčič Zuljan and Kalin, 2020), while including inter-subject connections. When teaching scientific and technical contents, drawing and modelling are also important (Valenčič Zuljan and Kalin, 2020;Anning, 1997;Hallström, Elvstrand, and Hellberg, 2015). Mawson (2010) found that opportunities for pupils to draw as a form of technical activity are lacking. As he exposes, learning various techniques of drawing and modelling would enable students to obtain technical language useful to express their ideas. Teaching methods of written works and of work with texts are also important in achieving scientific and technical literacy. Ritchie, Tomas, and Tones (2011) refer to the importance of pupils' activity and creativity in writing and reading. Several researchers (Hand andPrain, 1995, as cited in Ritchie, Tomas, andTones, 2011;Prain and Hand, 1996, 1999, as cited in Ritchie, Tomas, and Tones, 2011, found that diversified writing tasks, including more imaginative writing, have been shown to assist students' learning processes, improve learning outcomes, have strong motivating effects, and impact positively on students' attitudes and engagement. In this context, the use of student-generated narratives is important. While narrative writing is not traditionally connected to teaching Science and Technics, it attracts pupils and has encouraging effect on them. Wellington and Osborne (2001, as cited in Ritchie, Tomas, and Tones, 2011) think that it helps children express their thoughts in written language through being personally engaged (p. 76), it also offers opportunities to connect personal experiences with science ideas (Hand et al., 2001, as cited in Ritchie, Tomas, andTones, 2011;Hodson, 2009, as cited in Ritchie, Tomas, andTones, 2011). Moreover, Avraamidou and Osborne (2009) seriously reflect on the question: How can the conceptual complexity of scientific information be translated into 'everyday' language without minimizing its value? A challenge for teachers, according to Vosniadou et al. (2001) should be the creation of interesting and challenging learning environments where teachers will encourage students to actively participate and direct themselves towards their own goals, building and nurturing the students' natural desire to explore. Mihaliček (2011) states that encouraging learning environment and the use of modern didactic strategies contribute not only to the quality of teaching, but also to the satisfaction of pupils and their teacher. He exposes it as an important teacher's competence. McRobbie, Ginns, and Stein (2000) emphasize that teachers should be able to plan and implement learning experiences that would engage students in the generation and evaluation of ideas, and the use and evaluation of design practices to construct a technological artefact. Despite the importance attributed to the teaching method for practical work, activities and products, when pupils make artefacts, get to know various materials and acquire skills within the framework of technology education, the education process should not remain at that level only. Mawson (2007) points that in teaching Science and Technics great emphasis is on making artefacts, while the discussions on broader questions regarding the nature of technology and connections between technology and society are less frequent. (Mawson, 2010, p. 10) The latter is particularly important for the development of pupils' technology literacy. Twyford and Järvinen (2000) point at the value of problem teaching that "brings authenticity to classroom experiences for pupils". Technological problem solving is a form of reflective thinking in which the child interacts with many sources of knowledge in the process of solving a problem. The pupil's mind changes and develops through active participation.
When teaching scientific and technical activities, particularly in younger pupils, the play-based learning method is also important. Boser, Palmer and Daugherty (1998) and Wolters (1989) found the greatest impact on developing a positive attitude toward technology was playing with technological toys, such as LEGOs, Tinkertoys, and Erector Sets.
Turja, Endepohls-Ulpe and Chatoney (2009) have established that not many studies research the play-based method in the context of technological education. When teaching scientific and technical contents to younger pupils, it is possible to apply role playing in various contents: pupils meet various professions, through play, they can get experiences on objects, materials and physical phenomena, through research and tasks, they learn to use tools and accessories (Turja, Endepohls-Ulpe and Chatoney, 2009). There can be individual or group play, which can be (psychomotor) skill-oriented or creative, focused on problem solving etc. Parker-Rees (1997) believes there are structural similarities between free play and design and technological activities, their common feature being encouraging creativity and critical thinking in problem solving. Play can contribute to language development and connecting abstract concepts and ideas with technological objects that are used during play. Free play can stimulate the ability to visualize or a certain kind of cognitive modelling, important in designing and technological activities (Parker-Rees, 1997).
Constructivist views are based on the research performed by many authors, such as Piaget, Vygotsky, Dewey (Marentič Požarnik, 2018). Piaget mostly derived from processes that a person uses to construct the understanding of the world; while Vygotsky -the founder of social constructivism, rather emphasizes the importance of dialogue in knowledge building (Marentič Požarnik and Cencič, 2003). In spite of different views constructivist-oriented researchers have, they share their emphasizing that individuals actively constructs their cognitive structures, when interpreting their own experiences in particular situations (Palincsar, 1998) or that learning means an active mental process, in which pupils themselves transform information into meaningful knowledge (Phillips, 1995). The teachers' role is to design a complex, challenging learning environment with original authentic tasks (Muijs and Reynolds, 2017), and to encourage and accept student autonomy (Moustafa, Ben-Zvi-Assaraf and Eshach, 2013).
It is pupil-oriented teaching (Valenčič Zuljan, 2002;Wilen, Hutchison and Ishler, 2008;Muijs and Reynolds, 2017) that emphasizes the importance of didactic principle of activity and individualization. Therefore, teachers should know children's concepts and experiences in addition to wrong and incomplete perceptions and consider them within the learning process. A teacher forms situations of socio-cognitive conflict and in the process of modelling offers children suitable support in solving the conflict. The teacher's support in cognitive conflict resolution and in the whole process of learning is very important (Valenčič Zuljan, 2002;Manentič Požarnik and Cencič, 2003). For quality learning, children should be able to acquire the knowledge according to different ways and various activities in a stimulating and innovative learning environment with a proper balance between individual and group work, research and discovering, and the teacher's systematic guidance and moderating (Barron and Darling-Hammond, 2013).
Deriving from the research problem, we formed three research questions: 1. When teaching scientific and technical contents, how often do class teachers introduce elements of cognitive-constructivist model?
2. Is the frequency of implementing elements of cognitive-constructivist teaching model connected to the teachers' concern about their own professional development?
3. Is the frequency of implementing elements of cognitive-constructivist teaching model connected to the following factors: The importance of scientific and technical contents; Need for Science and Technics education; Competence for quality teaching in Science and Technics; Professional enthusiasm, and Complexity of teaching Science and Technics.
In our research, we used quantitative research approach and descriptive and causal nonexperimental method of educational research.
The research included 167 class teachers from various primary schools in the Republic of Slovenia. Data were collected with three scales: a) ways of teaching scientific and technical contents; b) attitude to scientific and technical contents and teaching; c) components of professional development. We used the instrument, developed in the project "Culture of Educational Institution as a Factor in Co-Construction of Knowledge," and adapted it to our needs. 10 new statements were added to the scale Ways of teaching scientific and technical contents that was developed in the project and originally had 6 items. A factor analysis was carried out and Cronbach's reliability coefficients calculated for the new 16 item scale. The Cronbach's alpha reliability coefficients are as follows: the first factor (Importance of scientific and technical contents) .792; the second factor (Need for scientific and technical education) .798; the third factor (Competence for quality scientific and technical education) .674, the fourth factor (Professional enthusiasm) .719; and the fifth factor (Difficulty of teaching Science and Technics) .502.
Data were processed according to descriptive and inferential statistics. The data were processed in the IBM SPSS Statistics Version 27 statistical package. Correlation coefficients ( ) and factor analysis were used.
Factor analysis was carried out on the scale Attitude towards scientific and technical contents and teaching, consisting of 16 statements. The statements were abstracted into substantively five meaningful factors (KMO = 0.799; Bartlett's test of Chi-Square sphericity = 927.435 with p = .000). The method of factor extraction "Principal Component Analysis" was selected. The method of factor rotation is "Varimax with Kaiser Normalisation". The reliability coefficient of this scale is Cronbach's alpha .850. Table 1 presents eigenvalues, explained variances and the number of factors obtained. Table 2 presents the matrix of factors (a set of factors).

Factor 2 -entitled Need for scientific and technical education explains 10.796% of total variance. Factor 3 -entitled Competence for quality scientific and technical education explains 8.843% of total variance. Factor 4 -entitled Professional enthusiasm explains 6.952% of total variance. Factor 5 -entitled Difficulty of teaching Science and Technics explains 6.609% of total variance.

Frequency of implementing various elements of cognitive constructivist way of teaching scientific and technical contents
Teachers assessed 6 statements that defined elements of cognitive constructivist way of teaching scientific and technical contents. Since the cognitive constructivist way of teaching points out mental activities of pupils, all the statements were designed so that they originated in the descriptions deriving from pupils' activities.
When forming individual statements we relied on various descriptions of cognitive constructivist model (Sparks-Langer et.al., 2000;Valenčič Zuljan, 2002), that emphasize the importance of pupils' activities in collecting information to test hypotheses, in reflective observation and asking questions, formation of hypotheses, performance of various experiments, verification of hypotheses, as well as the analysis and generalization of conclusions.

The

shares of assessed frequency of implementing various elements in teaching scientific and technical contents
The table 3 shows that in no item grade 5 appears in the first position -I do very often (regularly), somewhat higher rate appears in items Pupils perceive phenomena and ask questions (24.3%) and Pupils carry out experiments (21.9%).Grade 4 -I do often appears in the first position / with the highest share in three items: Pupils perceive phenomena and ask questions (56.2%), Pupils collect information with research problem tasks (53.0%) and Pupils carry out experiments (47.9%). Grade 3 -I do at times figures first in three items: Pupils formulate assumptions (hypotheses) on possible answers to questions or solutions to problems (47.9%); Pupils examine assumptions (58.6%), and Pupils analyze obtained results and draw conclusions (51.5%). Grade 2 -I do rarely has a somewhat higher share in three items: Pupils formulate assumptions (hypotheses) on possible answers to questions or solutions to problem (36.1%); Pupils examine assumptions (20.7%), and Pupils analyze obtained results and draw conclusions (24.3%).
Is the frequency of implementing various elements of cognitive-constructivist way of teaching scientific and technical contents connected to teachers' concern of their own professional development?
We wanted to know whether the frequency of implementing various elements of cognitiveconstructivist way of teaching scientific and technical contents was connected to the teachers' concern of their own professional development, and this was covered in two items: using new scientific research www.ijcrsee.com 30 findings in the domain of learning, teaching and other subject matter and reflecting on their own pedagogical practice.

Table 4
Assessing items on teachers' concern of their own professional development In both items grade 4 occupies the largest share (Table 4) -Mostly typical 64.5% of teachers estimate to be "mostly" typical for them to use new scientific research findings from the domains of learning, teaching and other subject matter, and 56.2% to be mostly typical for them to regularly reflect on their own pedagogical practice. Grade 5 -absolutely typical with its share of 11.2% appears for item "In my work, I use new scientific research findings from the domains of learning, teaching and other subject matter" and with 24.3% share for the statement I regularly reflect on my own pedagogical practice.

Table 5 Correlation coefficient ( ) between the teacher's concern for their own professional development and the frequency of implementing various ways of teaching scientific and technical contents
Teachers who regularly reflect on their own pedagogical practice, statistically significantly more often organize classes, where pupils perceive phenomena and ask questions (p = .004); collect information with . Cognitive constructivist way of teaching scientific and technical contents, International Journal of Cognitive Research in Science, Engineering and Education (IJCRSEE),9(1),[23][24][25][26][27][28][29][30][31][32][33][34][35][36] research problem tasks (p = .004; formulate assumptions (hypotheses) on possible answers to questions or solutions to problems (p = .001); and examine assumptions (p = .006).

Correlations between factors and the frequency of implementing various elements of cognitive constructivist way of teaching scientific and technical contents
We were interested whether factors Importance of scientific and technical contents (factor 1); Need for scientific and technical education (factor 2); Competence for quality scientific and technical education (factor 3); Professional enthusiasm (factor 4), and Difficulty of teaching Science and Technics (factor 5) are statistically significantly connected to the frequency of implementing various elements of cognitive constructivist way of teaching.

Table 6
Correlation coefficients ( ) between factors and the frequency of implementing various ways of teaching scientific and technical contents Table 6 shows there are no statistically significant connections between factor 1 Importance of scientific and technical contents and the elements of implementing cognitive constructivist way of teaching scientific and technical contents. Neither are there statistically significant connections between factor 2 Need for scientific and technical education and the elements of implementing cognitive constructivist way of teaching scientific and technical contents.
Factor 3 competence for quality scientific and technical education is statistically significantly connected to all six elements. Teachers who rate higher their competences to teach Science and Technics, statistically significantly more often organize classes where pupils perceive phenomena and ask questions (p = .001); collect information with research problem tasks (p = .000); formulate assumptions (hypotheses) on possible answers to questions or solutions to problems (p = .001); examine assumptions (p = .007); carry out experiments/tests (p = .016); analyze obtained results and draw conclusions (p = .001). Factor 4 Professional enthusiasm is statistically significantly connected to four elements. Teachers who express a higher degree of enthusiasm, statistically significantly more often organize classes where pupils perceive phenomena and ask questions (p = .010); examine assumptions (p = .013); carry out experiments/tests (p = .000); analyze obtained results and draw conclusions (p = .012). Factor 5 Difficulty of teaching Science and Technics is statistically significantly connected to two elements. Teachers who rate higher the difficulty of teaching Science and Technics, statistically significantly more often organize classes where pupils examine assumptions (p = .001); analyze obtained results and draw conclusions (p = .013).

Discussions
To achieve high-quality knowledge of pupils it is crucial to respect the didactic principle of learning activity. Cognitive constructivist teaching model is based on the assumption that pupils actively build the system of their own knowledge, with teachers having the role of providing adapted cognitive in emotional support. In our research, pupils' activities are covered in 6 elements of cognitive constructive model. We found out that out of the six elements of cognitive constructivist teaching model, teachers often organized activities where pupils perceive phenomena and ask questions (56.2%), collect information with research problem tasks (53.%) and carry out tests (47.9%). Activities where pupils formulate assumptions (hypotheses) on possible answers to questions or solutions to problems (47.9%); where pupils examine assumptions (58.6%) and where they analyze obtained results and draw conclusions (51.5) were carried out occasionally. It has to be pointed out that grade 2-I do rarely has a somewhat higher share in three items: pupils formulate assumptions (hypotheses) on possible answers to questions or solutions to problem (36.1%); pupils examine assumptions (20.7%), and pupils analyze obtained results and draw conclusions (24.3%).
The research showed that the elements of cognitive constructivist way of teaching scientific and technical contents were more often organized by teachers who rated higher their competence. The importance of competent teachers for quality implementation of their professional role is confirmed in numerous studies (Brophy and Good, 1986;Marzano, Pickering and Pollock, 2006;Hattie, 2009Hattie, , 2018Darling-Hammond and Richardson, 2009). Deriving from the obtained results, it is important that already during their studies students have opportunities to obtain insights into characteristics of cognitive constructivist way of teaching and develop skills of forming a cognitive conflict and of scaffolding as basic characteristics of cognitive constructivist model. The very elements of formulating hypotheses and their examination are the items for which a greater share of teachers claim their rare implementation. It is necessary to emphasize that cognitive conflict and providing scaffolding for pupils who have various capabilities, previous knowledge and motivation requires from teachers to observe the didactic principle of learning differentiation and individualization.
If students are to be trained in cognitive constructivist way of teaching scientific and technical contents, it is important that they themselves receive this way of teaching during their studies (Richardson, 1997;Valenčič Zuljan, 2007). In this context, didactic strategies of "open teaching" are important -such as problem-based approach, project work, research teaching. Numerous studies point out the importance of problem-based approach (Roth, 1995, as cited in McRobbie, Ginns andStein, 2000;McCormick et al., 1996, as cited in McRobbie, Ginns andStein, 2000) for heightening the awareness of technology and technology education. (Andersno & Walvoord, 1990, 1993, as cited in McRobbie, Ginns and Stein, 2000Shapiro, 1996;Swain, 1991;Tyler, 1992). "The problem-solving access to educational content is always in the function of enabling students to experience, understand and evaluate the content that is being studied." (Mezak and Pejić Papak, 2019). Organization and teaching procedures should be chosen to maximize and sustain the student's thought activity and contribute to their conclusions and decision abilities.
McRobbie, Ginns and Stein (2000) carried out an investigation, using an interpretive research methodology, of preservice primary teachers' prior perceptions of design and technology and changes in their perceptions of design and technology as a result of their engagement in independent technology projects. In the research, there were 130 participants, enrolled in a one-year postgraduate teacher education program. Research findings confirmed the importance of including independent technology projects in courses for preservice primary teachers as a way of changing their perceptions of technology and technology education. Numerous studies (Anderson & Walvoord, 1990, 1993, as cited in McRobbie, Ginns and Stein, 2000Shapiro, 1996;Swain, 1991;Tyler, 1992) confirm that engagement in independent investigations can stimulate changes in students' thinking and a broader understanding of technology. . Cognitive constructivist way of teaching scientific and technical contents, International Journal of Cognitive Research in Science, Engineering and Education (IJCRSEE),9(1),[23][24][25][26][27][28][29][30][31][32][33][34][35][36] What is crucial is the experiential learning of students future teachers through current open downtoearth problems, as this contributes to a deeper personal understanding of learning contents and increased professional enthusiasm.
The research showed that teachers with a higher level of enthusiasm statistically significantly more often carried out elements of cognitive constructivist teaching model and more often organized classes where pupils perceive phenomena and ask questions; examine assumptions; carry out tests, and analyze obtained results and draw conclusions. The importance of teacher's enthusiasm has been confirmed in numerous studies (Rosenshine, 1970;Rosenshine and Furst, 1973;Brophy and Good, 1986;Patrick et al., 2003;Turner et al., 1998). Brophy and Good (1986) define ''teacher enthusiasm'' as one of the teacher qualities that significantly influences effective teaching. Rosenshine (1970), and Rosenshine and Furst (1973) established that teacher's enthusiasm and passion for the subject they teach correlate with pupils' achievements. Therefore it is important for students and teachers to be familiar with studies on the impact of teacher's enthusiasm, and also to research their own teaching in the perspective of the influence of enthusiasm on pupils. Lončarić and Pejić Papak (2009) emphasize the importance of teacher's research, which positively influences their professional commitment. Teachers' research is also an important factor of their professional development (Marentič Požarnik, 2018;Vogrinc and Valenčič Zuljan, 2009;Valenčič Zuljan, 2018).
The research showed no statistically significant differences between the frequency of implementing elements of cognitive constructivist way of teaching scientific and technical contents and factors Importance of scientific and technical contents and Need for scientific and technical education. We found out that teachers who rate higher the difficulty of teaching scientific and technical contents statistically significantly more often implement two of the six elements of cognitive constructivist model of teaching, namely they more often organize classes where pupils examine assumptions; analyze obtained results and draw conclusions.
Our research showed that the elements of cognitive constructivist way of teaching are more often organized by teachers with greater concern of their professional development, in our research measured with observance of new scientific research findings referring to learning, teaching and other subject matter as well as the reflection on their own pedagogic practice. In view of our study findings and the fact that professional development presents one of the basic competences of the modern teacher, it is important that already during their studies students future teachers are familiarized with the research on teacher's professional development and raised to awareness that taking care of their professional development is a basic value.

Conclusions
The results of our study lead to the conclusion that all 6 elements of cognitive constructivist way of teaching should be strengthened, since grade 5 -(very often) does not have a high share in any element, which however would be expected given the importance of cognitive constructivist way of teaching scientific and technical contents. For quality teaching of natural and technical contents, the share of the following three items should particularly be strengthened: Pupils formulate assumptions (hypotheses) on possible answers to questions or solutions to problem; Pupils examine assumptions, and Pupils analyze obtained results and draw conclusions.
Data from our research lead to the conclusion that the frequency of implementing elements of cognitive constructivist teaching model is linked to the teachers' concern for their own professional development, since those who use new scientific research findings in their work and regularly reflect on their own pedagogical practice, statistically significantly more often organize elements (4 to 6) of cognitive constructivist way of teaching.
The research showed that the frequency of implementing elements of cognitive constructivist way of teaching is statistically significantly connected to 3 out of 5 factors: Competence for quality scientific and technical education (in all 6 elements); Professional enthusiasm (in 4 elements), and Difficulty of teaching Science and Technics (in 2 elements).
It would be sensible to continue research, which would additionally help shed light on the reasons for the findings of our study, among others class teachers' attitudes to the importance of cognitive constructivist way of teaching, what obstructs them in introducing this way of work, in which elements they would need additional support at the level of school or support in additional education at the system level, etc.
