Problem based learning approach increases the academic satisfaction of health science students in Ethiopian universities: a comparative cross sectional study.

BACKGROUND: Problem based learning is being highly implemented in many medical schools worldwide due to its perceived advantages including improvement of problem-solving abilities, development of communication skills, creation and development of critical thinking skill, and making of individuals to be lifelong learners & responsible for their own learning process.
OBJECTIVE: The study aimed to compare academic satisfaction of Problem and Lecture based learning of regular undergraduate health science students in Ethiopian Universities, 2021.
METHOD: Institution based comparative cross sectional study was conducted from February 1-30, 2021. Data were collected using a pretested structured and self-administered questionnaire among 850 eligible students from two Universities. Data were entered into EPI info version 6.04 and analyzed using SPSS version 23. Binary Logistic regression model was fitted to identify factors associated with academic satisfaction considering the association to be significant p- value < 0.05. RESULT: The study result revealed that the magnitude of academic satisfaction among problem based and lecture based learning students were 50.9 and 49.9% respectively. Similarly, problem based learning students were more likely to be academically satisfied than lecture based learning students in their type of curriculum with (AOR = 1.50, 95% CI = 1.02, 2.21). Experience of classroom distress (AOR = 1.93, 95% CI = 1.22, 3.06), quality of teaching (AOR = 0.54, 95% CI = 0.34, 0.86), relationship with classmates (AOR = 0.33, 95% CI = 0.13, 0.80), course content (AOR = 0.56, 95% CI = 0.33, 0.93) and accessibility of technology in the campus (AOR = 0.62, 95% CI = 0.40, 0.96) were the significant factors of academic satisfaction of problem based learning students. Year of study (AOR = 0.29, 95% CI = 0.17, 0.48), quality of teaching (AOR = 0.51, 95% CI = 0.31, 0.85), course content (AOR = 0.59, 95% CI = 0.35, 0.97) and energy & effort (AOR = 0.55, 95% CI = 0.35, 0.88) were significantly associated with academic satisfaction among lecture based learning students.
CONCLUSION: The study revealed that the academic satisfaction among problem based learning students was higher than lecture based learning students. Incorporating and implementing problem based learning as a formal instructional method in across the universities curriculum is recommended.

Introduction

In health science education teaching and learning has become very important [1]. Problem-Based Learning (PBL) has been defined as an instructional method which uses well-constructed clinical problems as a context for students to learn problem-solving skills and acquire knowledge about the basic and clinical science [2]. It involves students working in small groups of five to ten to analyze problem or case scenarios as a basis for achieving the three learning domains [3]. There was a growing interest over the past decade for a paradigm shift from a traditional lecture-based mode of delivery to an active student-centered method [4]. PBL was first introduced in 1969 at McMaster University’s Faculty of Health Sciences in Canada [5].

Problem based learning is being highly implemented in many medical schools worldwide due to its perceived advantages including improvement of problem-solving abilities, increased knowledge retention, better integration of basic science and clinical skills, development of communication skills, creation and development of critical thinking skill, and making of individuals to be lifelong learners & responsible for their own learning process [6]. Globally, it is practiced in many health science faculties and currently, it serves as an active pedagogy in many disciplines to improve the teaching and learning processes in educational systems [3, 7].

Problem based learning models can be seen as pure type first introduced at McMaster University to the Hybrid models adopted in many other institutions including Ethiopia. The Hybrid models of PBL contain the skeleton of PBL but, were supported by different teaching activities like lecture and skill training sessions to provide the continual knowledge base [8].

Currently, active student involvement in the learning process is increasingly believed as one of the key indicators of quality education. Ethiopian Education and Training policy also promotes the implementation of active learning in all educational institutions including Universities [9]. Related to this PBL have been implementing in Debretabor University under Hybrid innovative curriculum since 2014 for Health science college students only and a year back the Ethiopian ministry of education in collaboration with the Ministry of Health was planned for its implementation in all higher education institutions as part of experimentation for health science faculty students whereas Mekelle University has been implementing the conventional lecture-based method to its Health science college students till the last 1 year starting from that it is on the way to start using PBL as one instructional method.

In line with education, student satisfaction defined as the favorability of a student’s subjective judgment of the various results and experiences associated with education [10].

Student satisfaction is basic for educational institutes, especially Universities but in reality, student satisfaction has never given an attention by academic authorities nor regarded as a matter of survival by higher education institutions. It implies that the impact of educational services given by a university on its student’s level of satisfaction has largely been an area that remains unexplored [11].

Therefore, this study is aimed at comparing student’s academic satisfaction with different instructional methods as it is one indicator of quality education which is among the three pillars of excellence or mission of higher education institutions shared in common. In addition, factors associated with academic satisfaction of students were also identified. Since there is no study conducted in the two study areas the result of this study will contribute as part of improving the satisfaction of regular undergraduate students in academic activities.

Methods

A cross-sectional study was conducted at Debretabor and Mekelle Universities from February 1 to 30, 2021. Debretabor University is found in Debretabor town, Amhara regional state and have been use PBL as a formal educational method since 2014 for its health science students where as Mekelle University is found in Mekelle city, the capital of Tigray regional state, Ethiopia and was using LBL method. Both universities had a health science college with 3301 regular undergraduate students enrolled and six departments each were used for the study. Those departments were Medicine, Pharmacy, Midwifery, Nurse, Clinical laboratory and Anaesthesia. The total number of second and third year student’s for the academic year in both Universities were 1053.

Study population

All second and third year regular undergraduate health Science College students found in Debretabor and Mekelle Universities during period of data collection. Inclusion criteria; All second and third year regular undergraduate health Science College students found in Debretabor and Mekelle Universities.

Exclusion criteria

Students who transferred to DTU in the academic year from other universities those were not yet use PBL as one instructional method and who transferred to MU from other Universities that were using PBL as one instructional method were excluded. Since, there were no transferred students in both Universities all second and third year students (1053) were included in the study.

Variables of the study

Academic satisfaction (five-point Likert scale merged as Satisfied or Unsatisfied) is the dependent variable. Independent variables were Socio-demographic characteristics: (Age, sex, religion, ethnic group, department, year of study & family’s educational level). Personal related factors: (Preferred learning style, Experience of classroom distress, GPA, Learning approach, Time investment, Energy and effort). Institutional factors: (Curriculum, teaching method, Quality of instructors, Quality of feedback, Student assessment, Staff helpfulness, Student centeredness) [12-24].

Data collection procedure

Data were collected by self-administered structured and pretested questionnaire. The questionnaire was adapted from previous similar studies done at the College of Medicine, King Saud University, at King Abdulaziz University in Jeddah, Saudi Arabia and others [1, 25–41].

After the data has checked for completeness and accuracy, it was coded manually and then entered into Epi Info version 6.04 and exported to SPSS version 23 for analysis. Descriptive statistics were performed on numerical value, mean, frequencies to describe the study population about dependent and independent variables. The binary logistic regression model was fitted to determine the crude associations of each independent variable with academic satisfaction. Variables with a p-value of less than 0.05 were entered to multiple logistic regression for further analysis to control for confounding variables. Adjusted OR with 95% CI was used to estimate the strength of the association between independent variables associated with the outcome variable. Finally, variables with p-value < 0.05 were considered significantly associated with academic satisfaction. The Hosmer and Lemeshow goodness of fit test was used to check model fitness and indicated that the data was fitted for the model (p = 0.63).

Ethics approval and consent to participants

Ethical clearance was obtained from Mekelle University College of health sciences, institutional board review (IBR) and a letter of cooperation was also received from the head department of midwifery, college of health sciences, Mekelle University to each Universities. The objective and the aim of the research was explained to the study subjects on the information sheet of the questionnaire, verbal and written informed consent was obtained from each study subject after explanation of the purpose of the study and involvement (to be a participant) was after their complete consent. Any health science students who were not willing to participate in the study were not forced to participate, no personal identifications were included in the data sheet and all data taken from the participants were kept strictly confidential and used only for the study purpose.

Discussion

This Institution based comparative cross sectional study tried to assess and compare academic satisfaction and identified factors affecting the academic satisfaction of regular undergraduate health science students in selected Universities with different instructional methods.

In this study, it was found that the magnitude of academic satisfaction of regular undergraduate health science students on PBL was 50.9% and their counterpart was about 48.9%. This study finding is not consistent with the study conducted in Turkey University which showed that the satisfaction of undergraduate medical students with PBL instructional method was 64.6%. The possible reason might be due to the difference in the study participants which the current study included most of the departments under health science unlike the study conducted in Turkey University which were involved medical students exclusively and study setting [16].

This study revealed that factors associated with the academic satisfaction of PBL students as experience of distress in classroom, quality of teaching, relationship with classmates, course content and accessibility of technology to use in the campus where as factors significantly associated with the satisfaction of LBL students were year of study, energy and effort, quality of teaching and course content. In general factors that affect the satisfaction of PBL and LBL students in common were type of curriculum, quality of teaching and course content.

In this survey PBL students were more likely to be academically satisfied than LBL students with the type of curriculum implementing in their campus. Since, there is no similar research done for the factors of academic satisfaction with the adjusted odds ratio the authors could not compare this research finding with the previous findings in this discussion part.

The result of this study revealed that PBL students who had not experienced distress in classroom teaching learning process were two times more likely to be academically satisfied than students who had experience. As per the authors search since, there is no similar research done for the factors of academic satisfaction with the adjusted odds ratio could not compare this research finding with the previous findings in the discussion part.

Quality of teaching is another factor that affects the academic satisfaction of University students [17]. According to this survey finding PBL students who were not satisfied with the quality of teaching were less likely to be academically satisfied than the students who were satisfied with the quality of teaching in their campus.

Similarly, LBL students who were not satisfied with the quality of teaching were also less likely to be academically satisfied than the students who were satisfied with quality of teaching in the campus. Since, there is no similar research done for the factors of academic satisfaction with the adjusted odds ratio could not compare this research finding with the previous findings in this discussion part.

Problem based learning students who were not satisfied with the relationship they had with their classmates were less likely to be academically satisfied than their counterparts.

Both PBL and LBL participants who were not satisfied with the course contents of their main subjects were less likely to be academically satisfied than their counterparts.

Accessibility of technology is also one major factor contributing for student’s satisfaction in higher education institutions. As of this study result PBL students who were not satisfied with accessibility of technology to use in the campus were less likely to be academically satisfied than those who were satisfied with. This might be due to the fact that PBL instructional method by its nature is mostly dependent on accessibility of technology that all students should get access to the internet even in the PBL sessions to make student’s learning process evidence based. Similar reason here as the above not to compare this study finding with others.

This study showed that year of study of the respondents among LBL had a significant influence on the academic satisfaction of students. Being a second year student is less likely to be academically satisfied than being a third year.

According to this research finding Lecture based learning students who were not satisfied with the appropriateness of energy and effort using in their learning were less likely to be academically satisfied than their counterpart. In order to compare this finding with others finding the authors could not get similar research findings.

Limitation of the study

This study did not include students other than regular, which might affect its generalizability.

In general, as per the authors search the articles that we found in this area were descriptive in nature and we could not find literatures done using logistic regression analysis with AOR similar with this study finding so we could not compare our study result with other researcher’s finding in the discussion part.

Conclusion

The magnitude of academic satisfaction among PBL students was higher than LBL students in selected higher education institutions of Ethiopia as this study result showed. Experience of distress in classroom, quality of teaching, relationship with classmates, course content and accessibility of technology to use in the campus were statically associated with the outcome variable independently among problem based learning participants were as year of study, energy and effort, quality of teaching and course content were factors that are statically associated with the outcome variable independently among lecture based learning participants.

This research revealed that the magnitude of academic satisfaction among PBL students was higher than LBL students. Ministry of science and higher education and educational experts may give attention to improve the academic satisfaction of students learning with LBL method to ensure quality education across all the universities to produce qualified health care providers there by decrease the health issues of the community. This can be address by incorporating PBL across all higher education institutions as a formal instructional method and making use of appropriately to make health science students satisfied with the academic activities in their campus and make them competent in their profession.

Recommendation

To ministry of science & higher education

Incorporating PBL as a formal instructional method in the curriculum across higher education institutions of Ethiopia to enhance the academic satisfaction of health science students thereby increase and maintain the quality of education and achieve one of its missions.

Since energy and effort that the LBL respondents are investing in their learning is one influencing factor of academic satisfaction in this study incorporating PBL method will resolve the problem as in its nature is constructivist that the students are the owner of their learning and involve in the construction of their own understanding to the subject matter and developing this habit will help them to use appropriate energy and effort in their learning process.

To the university administrators

In order to improve the academic satisfaction of PBL students the University administrators of DTU need to make sure that the accessibility of technology in the campus.

It is necessary that to assess and check the quality of education periodically in both universities by preparing quality measurement tools of the teaching learning process even by participating students. In addition it’s better for administrators to prepare and facilitate programs that aim in curriculum review to make it acceptable to the students of interest.

To researchers

It is recommended that researchers are better to do more research in this area by including all students of higher education institutions regardless of their academic program in health science to improve the quality of health science students there by increasing the quality of health services given in the country.

Further study of factors associated with the academic satisfaction of higher education institutions using the regression analysis is recommended.
