This study explores how the implementation of problem-based learning (PBL) in technical and vocational education training (TVET) systems of Nigerian higher education (HE) can enhance quality graduate outcomes. The study also explores the issues and challenges of PBL implementation in the TVET system of Nigerian HE.

This study follows the assumptions of qualitative research. The authors interviewed 55 participants and had a focus group with 7 TVET postgraduate students. The 55 interviewees were drawn from TVET teachers (n = 33; 24 males and 9 females), Directors at National Board for Technical Education (n = 4; 3 males and 1 female), Directors of National Directorate of Employment (n = 5; 3 males and 2 females), Directors at the Federal Ministry of Education (n = 3 males), and industry executives (n = 10; 7 males and 3 females). Data were collected through a semistructured interview approach, transcribed and coded using NVivo 12 plus and analyzed through thematic analysis.

The results show that PBL in the Nigerian TVET system has positive implications for quality TVET graduate outcomes in that it can enable integrating theory and practice, motivate learning, improve students' self-efficacy, allow students to construct learning on their own, enhance graduate competencies and graduate employability. It also revealed six perceived possible major challenges to effective implementation of PBL in the Nigerian TVET system, which includes inadequacy of teaching and learning facilities; corruption in Nigerian education sector; recruitment of unqualified incompetent TVET teachers; difficulties in identifying real-life problems, among others. Participants offered benchmarks and actions and standards for improving the identified challenges, which formed a framework for coping with issues, challenges, and barriers to effective implementation of PBL in the TVET system of Nigerian HE (Table 1).

The results of this study are original and serve as an advocacy for Nigerian HE authorities to explore how PBL can be implemented in the TVET system to improve graduate outcomes. The study serves as a starting point for more research in the domain of improving the quality of TVET programs in Nigerian HE. Industry leaders and policymakers in Nigeria and other developing countries could use the findings from this study to increase HE and industry participation and partnership for quality of TVET program.

This study explores how career training with mentoring (CTM) programs work in Nigerian higher education (HE) institutions to foster students' career development and employability of graduates. It also explores how Nigerian HE curriculum can be adequately used to facilitate CTM as well as possible constraints to effective implementation of CTM programs in Nigerian HE institutions.

The study draws on interviews with well-qualified and experienced experts from six Nigerian public universities (each from the 6 geo-political zones of Nigeria), and 20 industries also within the same 6 geo-political zones of Nigeria that were selected for this study using a purposeful sampling technique. The study interviewed 33 experts comprising 21 senior academics at Nigerian universities and 12 industry executives to reveal substantial information about CTM programs in Nigerian HE institutions.

Drawing on the three key themes that emerged during the thematic analysis and linked to social cognitive career theory, it is clear that participants are convinced that CTM can enhance clarity about students' career ambitions, career interests, personal development plans and employability. Findings show that there are some career-related programs or activities that Nigerian HE students are presented with, but the programs have not been effective as to offer graduates quality career guidance and employability skills that employers demand. Acknowledging these, participants recommend establishing CTM centres in all Nigerian HE institutions to provide students with the opportunity to receive quality career advice, coaching and mentoring services while schooling.

The findings of this study shed light on varying resources required to cope with the demands of labour market in terms of supply of competent workforce that can contribute to Nigeria's economic growth and development. The findings are highly relevant for Nigeria and other developing countries' policy and research initiatives that aim to promote social inclusion and equity and improve better working conditions for all. The findings also have implications for career development and employability of HE graduates in developing world context.

Understanding the role that CTM programs can play in facilitating career development and graduate employability can arguably be of importance within the developing world context. This study, therefore, provides significant suggestions on how to build sustained HEIs and labour market partnership to foster career development and employability of HE graduates through establishing CTM centres in every Nigerian HE institutions.
