1. Introduction
Since the Lisbon European Council in 2000 included among its strategic purposes the promotion of an entrepreneurial culture, education systems have followed several objectives: emphasizing non-formal learning [
1], increasing university–enterprise relationships [
2], developing entrepreneurial competence in curricula [
3], and promoting transversal contents in different non-business university degrees and creating entrepreneurial in campus activities [
4]. While the majority of research on entrepreneurship education concentrates on university [
5] or pre-university levels [
6], there is an increasing interest in exploring the role of entrepreneurial education at the school level. A number of studies suggest that it is important to introduce entrepreneurship education before tertiary education [
7,
8].
In response to the challenges posed by globalization and digitalization, there has been a growing impulse towards entrepreneurship in education. European policies have encouraged this trend in its member states. In the Spanish case, it has becomes an objective of the educational system since 2006 [
9,
10,
11].
Entrepreneurial competence is recognized as having a “sense of autonomy and entrepreneurship”, being one of the eight key competencies for lifelong learning since 2018 in the EU [
12]. In addition, the European Framework for Entrepreneurial Competence: EntreComp, aims to provide a reference framework and a standard conceptual model to identify the elements that make up this competence and facilitate its inclusion in education systems [
13,
14]. It is worth noticing that entrepreneurial competence is part of the curriculum in Spain within Organic Law 3/2020.
The need to renew knowledge and boost entrepreneurial activity is increasing interest in improving entrepreneurial and financial skills at an early age [
15,
16]. Indeed, since 2012, OECD-driven financial competency has been incorporated into the PISA exams [
17]. An education that understands these competencies and empowers young people to have initiatives, make decisions, and develop projects that promote collective socio-economic improvements is an educational priority [
18]. Equipping students with these tools will help them in their personal [
19] and professional development [
20,
21] and contributes to the innovation and economic progress of society [
22]. These skills are essential in times of digital revolution and changes in the labor market [
23].
The inclusion of entrepreneurship education in school curricula has occurred gradually, either as a subject or as a transversal competence, in all educational stages [
24,
25], although it has a more substantial presence in secondary and higher education. However, teaching entrepreneurship is a challenging task due to its multifaceted and complex nature [
26]. Furthermore, its philosophical trend in education is still uncertain [
27]. Thus, recent reviews demonstrate the rise and multiple approaches to entrepreneurship education: educational levels, disciplines, tools, resources, content, assessment, pedagogies, etc. [
28]. Implementation in the classroom has been heterogeneous [
29] and usually generates some uncertainty [
8]. The literature detects the need to improve teacher training because they have a crucial role in its implementation [
30,
31,
32], the use of appropriate methodologies [
33,
34,
35], and the need to correctly evaluate it [
36,
37,
38].
In order to ensure positive results for students, it is essential to evaluate formal educational initiatives. This research on entrepreneurial education is based on consolidated theoretical backgrounds that define the influence of attitudes on entrepreneurship education, using intention models and the theory of planned behavior [
39,
40,
41], as well as theories of human capital and its connection to entrepreneurial intentions [
5,
6].
It is crucial to evaluate attitudes and knowledge that focus on business management, legal issues, and strategic vision to establish an entrepreneurial spirit. This analysis has yet to be carried out due to the recent incorporation of these materials into the educational school curriculum. Strengthening students’ identity and future entrepreneurial intention is crucial because the absence of it restricts the potential for creating entrepreneurial endeavors [
42,
43]. Moreover, it is important to explore different methods to ensure their success [
42,
44]. As part of the research, two groups of students were compared: those who only followed the entrepreneurial new curriculum and those who also participated in a specific training program. This program aimed to enhance the students’ entrepreneurial potential by providing training on personal indicators crucial for an entrepreneurial mindset. The results of both groups were evaluated to determine the effectiveness of the program.
This study provides empirical evidence demonstrating the positive impact of an entrepreneurial potential training program and curricula content on entrepreneurial knowledge among 1036 students. We seek to evaluate the influence that personal factors such as attitudes towards entrepreneurship may have on students’ learning process. Certain variables such as creativity, leadership, personal control, achievement motivation, and problem-solving are measured to verify [
37]. Reference article consists of three main sections. Firstly, a review of the theoretical framework of the curricular contents of entrepreneurship education is presented to establish the working hypotheses. We will explore how entrepreneurial competence is a combination of various skills and knowledge that can be enhanced through an educational program to improve the entrepreneurial abilities of students. Moreover, this study delves into how sociodemographic factors impact the development of entrepreneurial skills. In
Section 2, we will explain the methodology used to collect and analyze data from two separate groups (control and experimental). Additionally, the research findings will be presented according to the three levels of hypothesis testing: (1) the overall correlation between entrepreneurial attitude and entrepreneurial knowledge; (2) the observations regarding the curricular contents and students’ entrepreneurial knowledge in different groups; and (3) the impact of sociodemographic variables on entrepreneurial knowledge acquisition. Finally, we will discuss the results and compare them with the previous literature from similar studies. We will also establish recommendations for educational policy, describe the limitations of the study, and suggest possible future lines of work.
3. Materials and Methods
Education plays a crucial role in the development of human capital. Therefore, it is necessary to conduct empirical studies to assess the effectiveness of various components of the educational process. Following the research line of evidence-based education, we have conducted a quantitative analysis in order to give light on new curriculums and specific training programs at the school level. In this section, we will explain the hypotheses and the design of the methodology, including the instruments and the compositions of the groups for testing the efficacy of the programs and the new curriculum. Furthermore, the hypotheses are discussed.
3.1. Development of Hypotheses
Based on the scientific literature, several hypotheses have been put forward to evaluate the impact of the program of entrepreneurial potential on students, as well as the updated curriculum on entrepreneurship for secondary education, vocational training, and high school students.
The hypotheses are grouped into three levels of verification to study the relationship of the entrepreneurial attitude, hereinafter referred to as ATE, with entrepreneurial knowledge, hereinafter referred to as CON, as follows:
- (1)
Based on the previous literature grounded in entrepreneurial intention theoretical models and the theory of planned behavior [
39,
40,
41], we have formulated two hypotheses to test the overall correlation between entrepreneurial attitude (ATE) and entrepreneurial knowledge (CON).
Hypothesis 1. Before the educational intervention of the entrepreneurial potential program, students with higher attitudes toward entrepreneurship have higher entrepreneurial knowledge.
Hypothesis 2. Students who receive a specific educational program of entrepreneurial potential increase entrepreneurial knowledge and attitudes.
- (2)
In order to examine the various relationships between the entrepreneurial knowledge (CON) of students in the experimental and control groups, we have proposed two hypotheses. These hypotheses are based on the concepts of entrepreneurship-specific human capital [
5,
57,
61], previous research on the effects of entrepreneurship education [
6,
51], and studies on curriculum content and teaching methods [
67].
Hypothesis 3. Curricular contents on entrepreneurship improve entrepreneurial knowledge, as a whole and in each of its factors, regardless of whether the students have taken a specific program on entrepreneurial potential.
Hypothesis 4. Students who have received a specific program on entrepreneurial potential increase their entrepreneurial knowledge, as a whole and in all its variables, more than those who have not received it.
- (3)
Finally, in order to examine the connections between the dependent variables and entrepreneurial knowledge, we have formulated a hypothesis based on research into entrepreneurship education and factors such as gender, type of school, and parents’ socio-educational background [
62,
63,
64,
70,
71]. The hypothesis is as follows.
Hypothesis 5. The acquisition of entrepreneurial knowledge is related to other variables such as the gender of the students, the ownership of the schools, the educational level of the parents, or the level of education the students attend.
3.2. Instruments
Two measurement instruments were used to test the hypotheses:
- (1)
The
Basic Business Knowledge Scale (CON) is composed of 18 items distributed in three dimensions: business management knowledge (9 items), legal knowledge (5 items), and strategic knowledge (6 items). Cronbach’s alpha coefficient is adequate, ranging from 0.76 to 0.83 for each dimension [
42].
- (2)
The
Attitude Toward Enterprise Test (ATE-S), Spanish version, is composed of 22 items distributed in five dimensions: creativity (4 items), personal control (5 items), achievement motivation (5 items), leadership (4 items) and intuition for problem-solving (4 items) and with α = 0.853 [
37].
3.3. Description of the Sample
The surveys were conducted using stratified probability sampling during the 2021–2022 academic year. When analyzing the data, we considered the location (Autonomous Community), student level, school ownership, and gender of the students. Forty-one educational centers participated from Andalusia, the Community of Madrid, Castilla-León, Valencian Community, Castilla-La Mancha, La Rioja, Basque Country, and Navarre. The participants were split into two groups from the same educational center. One group served as the control and did not participate in the program, while the other was the experimental group, which underwent specific program training for entrepreneurial potential. Participation in the research was voluntary, and they were informed about the research objective, procedures, and the anonymized treatment of the data. A total of 1036 students participated, 440 in the control group (42.5%) and 596 in the experimental group (57.5%) (
Table 1).
The process complies with ethical and legal standards of anonymity and data protection.
3.4. Models and Studies Conducted
The statistical tests have been performed for data analysis and hypothesis testing. Non-parametric statistics are used to analyze the data, compare the groups at different times and evaluate whether there are significant differences. Wilcoxon tests with Lilliefors correction are used for related or independent samples, and the Kruskal-Wallis test is used to compare more than two groups. The measure of effect is obtained using the confidence interval for the medians (95%). In the statistical tests, those in which the
p-value < 0.05 will be considered significant. The Chi2 test is used to analyze the dependence of two variables. When necessary, simple correspondence analysis is used to analyze dependence. Finally, to move from a numerical scale to an ordinal scale by intervals, the following criterion has been used: Qi/i∈{1,2,3} being each of the three quartiles for each of the sections of the variable (
Table 2).
The checks are performed using the statistical program R software version 4.3.0. All the results are in the development of the following relationship analysis model (
Figure 1).
The variables compared are entrepreneurial knowledge (CON).
The results of the analyses of the described tests are shown below.
4. Results
To establish a relationship between ATE.PRE and CON.PRE, a linear regression model cannot be used due to the failure to meet the normality condition for the residuals. Therefore, the Chi2 test is utilized to test Hypothesis 1. Before the educational intervention of the entrepreneurial potential program, students with more attitudes toward entrepreneurship have greater entrepreneurial knowledge.
An analysis is performed on the relationship between the two variables which have been divided into three tracts. The contingency table and the Chi2 contrast yield the following results (
Table 3 and
Table 4).
The test shows a
p-value = 0.00005304 < 0.05, so the independence of both variables is rejected. Therefore, the dependence relationship between them is analyzed by means of correspondence analysis (
Figure 1).
In
Figure 2, it is illustrated that there is a correlation between students who have high ATE.PRE and CON.PRE scores. It should be noted that this correlation has not been verified for students who fall under the middle and low score categories. To summarize, Hypothesis 1 is supported insofar as pre-intervention data shows that students possessing strong entrepreneurial attitudes also exhibit notably higher levels of knowledge.
Regarding Hypothesis 2, it suggests that students who undergo a targeted educational program on entrepreneurial potential will exhibit an increase in their entrepreneurial knowledge and attitudes (measured by ATE.POST and CON.POST in the experimental study). However, a linear regression model could not be fitted, so we recoded ATE.POST and CON.POST using a three-stage criterion. The descriptive analysis of both variables, as well as the contingency table with the corresponding result of applying the Chi2 contrast for both variables, gives the following results (
Table 5 and
Table 6).
When the
p-value is less than 0.05 in a Chi2 test, such as
p-value = 0.0000, it indicates that the variables are not independent. This means that there is a relationship between the variables, and a correspondence analysis, shown in
Figure 3, can be conducted.
Figure 3 shows how the scores of the three tranches: high, medium, and low of the CON.POST variables are associated respectively with the high, medium, and low scores of the ATE.POST variable, thus confirming Hypothesis 2.
In relation to Hypothesis 3, it has been observed that the inclusion of entrepreneurship-focused curricular content enhances overall entrepreneurial knowledge (CON) and knowledge of individual factors (business management, legal framework, and strategy). This improvement has been noted regardless of whether the students have participated in a specific entrepreneurial potential program (CON.PRE with CON.POST). To further analyze the potential increase in knowledge and any differences between the experimental and control groups, thorough checks have been conducted. To analyze paired samples, we utilize the Wilcoxon test. Upon observing the control group (as displayed in
Table 7), it is evident that all comparisons between the before and after groups exhibit significant differences with a
p-value of 0.000, which is less than 0.05.
Research has shown that students who did not take part in the entrepreneurial potential program still displayed a significant increase in their overall entrepreneurial knowledge, including each of its individual factors. The same analysis is shown below for the experimental group (
Table 8), with an equally significant result for the knowledge variable and each of its factors (
p < 0.000).
In summary, after conducting the tests, it has been confirmed that Hypothesis 3 is applicable to both groups—those who received training on entrepreneurial potential through the program and those who only learned through the official curriculum. The differences between the groups were significant in all cases. The study has also shown that the curricular subject has a significant impact on the knowledge acquired by students, regardless of whether or not they took the specific program.
Regarding Hypothesis 4, it is believed that students who participated in the entrepreneurial potential program will have a greater increase in entrepreneurial knowledge compared with those who did not participate (both in the control and experimental groups). Various analyses will be conducted to determine the extent of this increase in knowledge among the different groups. The goal is to determine whether the increase in knowledge is particularly significant among students who completed the specific program. The results in entrepreneurial knowledge are compared using the Wilcoxon test in the two groups before (CON.PRE) and after (CON.POST) (
Table 9).
Based on the result
p = 0.10037, it appears that both groups begin at the same level. However, a significant difference is observed at a later time (POST), so we will examine this difference more closely. Upon comparing the factors of the knowledge dimension (CON) in both groups after the program (POST), we can see that there is a significant difference in all of them (as shown in
Table 10). This confirms Hypothesis 4.
Finally, tests are being conducted to validate the fifth hypothesis, which states that the acquisition of entrepreneurial knowledge is linked to various factors such as the gender of students, educational center ownership, parents’ education level, and students’ education level. The purpose is to determine if the increase in knowledge of students following a specific program is impacted by other variables.
Table 11 compares the scores obtained by men and women for entrepreneurial knowledge (CON) and its factors. It was found that there are no significant differences between genders for the CON variable and its dimensions.
To compare more than two groups, we applied the Kruskal-Wallis test (
Table 12). The difference between the groups is not significant, neither for the variable CON nor for the three factors according to center ownership.
In order to assess the influence of parental education, we utilized the categories of no degree, primary school, secondary school, vocational training, high school, and university. The resulting contingency table is displayed below (
Table 13).
It is important to mention that there is a high number of missing values in both variables: 146 for the mother’s education and 172 for the father’s. Additionally, the majority of the clustering is focused on the university level. With this condition, a new variable is constructed, which will be called Parents.Edu and is defined in 3 levels of grouping (
Table 14).
The Kruskal-Wallis test is used to compare the levels. As can be seen (
Table 15), the
p-values are very tight for the overall variable and for the factors. A large number of missing values is likely to have introduced trends, as the non-responses may not follow a random pattern. Therefore, the results are considered inconclusive.
After analyzing the data, the Kruskal-Wallis test was utilized to compare the educational levels (secondary, basic, or higher vocational training and higher education) of the four groups of students. Based on the findings, it appears that a significant relationship may exist between the CON variable and the educational level as a whole (as indicated in
Table 16). However, further examination of the results by factors shows that this relationship is not confirmed, particularly in the case of the strategy factor. Consequently, it can be inferred that while there may be some correlation between the students’ overall entrepreneurial knowledge and their educational level, this relationship appears not to be valid when examining the factors.
As a result, Hypothesis 5 cannot be confirmed for the variables of sex, tenure, and parents’ level of education. Nevertheless, it is clear that educational level has an impact on the entrepreneurial knowledge variable and its corresponding factors.
6. Limitations and Foresight
For the collection of data, due to the pandemic, reaching out to schools was delayed during the initial phase of the study, leading to some obstacles in the project.
Although the sample size is adequate, more than a thousand students and proportional among the school population participating would be possible to increase the sample size to deepen the analyses, as well as to extend it to the international level. It would also be appropriate to complete the research with a qualitative analysis that would provide balance and depth to the investigation. Furthermore, to improve our understanding of how entrepreneurship education affects students, we need long-term studies on their potential and achievements. We should also delve into sociocultural factors such as gender, the education system, and policies. Comparative studies across different countries and systems would help evaluate different curricula. Additionally, we should evaluate new methods that promote creativity and interdisciplinary programs for analyzing entrepreneurial intentions.
It should be noted that there is little research that relates the influence of attitude on the improvement of knowledge, so this research may open future lines to test the effectiveness of educational policies, as well as to improve the understanding of entrepreneurial competence and its implementation in the curriculum.
