PurposeThis study analyzes the significance of various attributes of developmental psychology developed by male and female students within higher education institutions (HEIs) in Cambodia. It also focuses on the mismatch between planned enrollments and the final selection of a course, and the knowledge and skills accessed during the study.Design/methodology/approachA sample of 463 students (267 female) was selected for a survey from two private and two public universities, located in both Phnom Penh and other provincial locations.FindingsIt was found that (1) the Cambodian Sustainable Development Goal targets related to quality education are likely to be achieved by 2030, but this will require close monitoring of the targets. While it is likely that the male ratio will be accomplished by 2030, this is less certain for the female ratio. (2) There was a mismatch between the planned enrollment and actual course selection for just under half (49.2%) of students surveyed due to high tuition fees, a lack of scholarships, unavailability of preferred courses, failure to gain admission and parental influence. This mismatch was higher for female students for all of these factors except for parental influence. (3) Students indicated a high degree of access to knowledge and skills, except for technological literacy, economic aspects and interpersonal effectiveness. Overall, male students were found to access a higher degree of both knowledge and skills. (4) The developmental psychology of students was found to be significantly influenced by decision-making ability, empathy, people skills, community engagement and voluntary work.Research limitations/implicationsThere were a number of limitations in carrying out this research. For example, discussions were separately organized at each university; the authors did not organize a consultative meeting gathering all the students from the four universities to discuss and get consensus. Moreover, the study did not cover the interviews of parents to gain their views regarding support for their children at HEIs.Practical implicationsImprovement in key aspects of developmental psychology for male students was found to be more significant than for female students, except for intellectual capacity.Social implicationsStill, improvement in the adopt of developmental psychology is required at HEIs in Cambodia and developing countries. Improved developmental psychology among students at universities has been shown to result in a significant enhancement in study performance and competencies. These competencies range from cognitive and intellectual capacity, associated with thinking and analysis; and emotional and social capacity, associated with the development of a societal vision. Students who develop cognitive and intellectual capacity tend to perform tasks more accurately and efficiently, make decisions more effectively and respond intelligently to new or complex circumstances. Students who develop emotional and social capacity are better guided toward focusing on caring for others in the community and establishing peaceful and safe environments. An important implication of the developmental psychology of students within HEIs in Cambodia is the holistic nature of education integrating knowledge, skills, competencies and social responsibility. HEIs should take on the role of equipping students with both cognitive and intellectual capacities for employment; as well as the emotional and social capacities required to build a society based on mutual trust and harmony. Improving the psychological development of students at HEIs in Cambodia may also be significant in achieving the CSDG targets. In terms of policy, HEIs should integrate opportunities for this to be included in the curriculum to increase the opportunities for students to engage in practice-based learning and community engagement activities. This will require providing sufficient learning materials and equipment to enable students to self-learn, think, analyze and innovate, using theories obtained in class, at home. This should be coupled with community engagement programs that provide students with the opportunity to work in the field. All knowledge and skills accessed by students should be integrated with the development of both cognitive and intellectual capacities. Further, social activities organized by HEIs are required to assist in developing the emotional and social capacity of students to interact with communities.Originality/valueThe paper is solely conducted and prepared by SOK Serey, CHEB Hoeurn, CHHINH Nyda, BO Chan Koulika and NGUONPHAN Pheakdey. The findings of the research produce both quantitative and qualitative information on the implementation of Sustainable Development Goals at higher education in Cambodia. In particular, this research is one of the most pioneer academic research studies conducted by a local scholar from Cambodia.
