This research aims to analyze the profile of students’ problem-solving ability in problems of optical instruments. This survey research involved 65 students class XI of MAN 3 Yogyakarta. The research instrument was in the form of 3 problem-solving questions in the form of a description. The results showed the percentage of students in the expert category was still relatively low at 30,7% and the students in the novice category were quite high at 69,3% so that students’ overall physics problem-solving abilities were relatively low. In this research, some student difficulties were still found, one of which was in determining the focus of the right lens for patients with eye disorders to use glasses and determine magnification when using a magnifying glass. Efforts to implement innovative learning are needed to improve problem-solving abilities in overcoming students’ physics problems.

PurposeThe purpose of this study is to investigate the role that communication, trust and digital transformation can play in the relationship between joint problem-solving and supply chain resilience. More specifically, the authors try to examine the possibility of digital transformation as a replacement for trust within a joint problem-solving context.Design/methodology/approachA survey instrument was developed and administrated to manufacturing firms within the United Kingdom and the United States. Based on data collected from 291 senior managers, multiple linear regressions were conducted through a customized process model to test the proposed hypotheses.FindingsThe results point to the actual impact of digital transformation being far more complicated than the initial benefits that it appears to bring within a supply chain. Thus, technology is only effective when applied within the right context. The authors showcase that the trio of digital transformation, trust and joint problem-solving can be highly valuable to establish supply chain resilience and that further investigation on the interrelationships between these concepts is warranted.Practical implicationsManufacturing firms that aim to adopt new technologies should not consider advanced digital technologies as an alternative to trust. While digital transformation can improve resource sharing and integration, governance mechanisms–such as trust–will remain the cornerstones of strategic supplier relationships. Therefore, supply chain partners must strive to achieve a balance between trust and the right type of digital technology.Originality/valueThis study contributes to the growing literature focusing on the role that digital transformation can play in developing supply chain capabilities. It adds an early empirical insight on the role of technology and governance in joint problem-solving and supply chain resilience.

The implementation of the 2013 Curriculum is to create a creative and innovative person. One of the right approaches is Problem Solving. Circulatory system material is the material that suits the problem solving approach. Less varied teaching materials will make the learning process becomes monotonous so that learners are not interested to learn. Therefore, a research aimed to produce problem-based solving module with mind map of circulatory system material for students of class VIII SMP.This research is a development research using development procedure from Plomp with three stages: initial investigation stage, development stage or prototype, and assessment phase. The object of this research is problem solving module minded mind map, and the subject of research is teachers and learners SMPN 15 Padang.Validity results obtained an average of 86.46% with valid criteria. The results of small group practice test (small group) obtained an average of 100% very practical category. Modular practicality test obtained an average result of 83.33% with practical category, while learners of 79.32% with practical category. It can be concluded that problem solving module with mind map about circulation system material for students of class VIII SMP has been valid and practical.

The concept of organizational leadership has engendered a lot of arguments. This is because the effect of leadership on every human endeavor cannot be over emphasized. This study examines the effect of organizational leadership styles, particularly transformational and servant leadership styles on deposit money banks (DMBs) employees’ performance in Nigeria. The study employs survey research design, through the administration of structured questionnaire on some selected employees of Guaranty Trust Bank, United Bank for Africa and First Bank. The research instrument was validated through content validity index, while test-retest method was employed in ascertaining the reliability of the research instrument. The findings revealed that transformational leadership and servant leadership styles have positive and significant combined effect on deposit money banks employees’ performance (F-stat= 58.02 *0.000). The adjusted coefficient of determination (adjusted R2) suggested that, 39.4% variation in employees’ performance is accounted for by transformational leadership and servant leadership styles. The t-value revealed that when the two variables (transformational leadership and servant leadership styles) are combined, they both have positive and significant effect on deposit money banks employees’ performance. Therefore, it can be concluded that transformational leadership and servant leadership styles both have individual as well as combined positive and significant effect on deposit money banks employees’ performance.

Purpose The purpose of this study is to understand the challenges faced by the higher educational institutes in imparting entrepreneurial education during the COVID-19 pandemic and to explore the institutional response to handle the difficulties posed by COVID-19 through innovative educational initiatives. Design/methodology/approach To understand the challenges faced, data was collected from entrepreneurship students and entrepreneurship educators through focus group discussions. The study followed Kitzinger (1995) as data was analyzed in its entirety as a group and then individually. Groups and individuals were the focus of the analysis. The study applies the Kepner Trego problem analysis technique (KPTA) as the problem-solving technique adopted by the institute and SAP-LAP (situation, actor, process, learning, action, performance) to discuss the findings of the study. Findings The study found that to engage, encourage and enable students to study on their start-up/business ideas; it is important to facilitate peer interactions, internships in start-ups and meaningful engagement with alumni entrepreneurs. Some proactive interventions are also expected from institutes to energize the student community with positivity. It is also important to nurture the emotional well-being of budding entrepreneurs. Research limitations/implications The case study narrates the innovative and agile problem-solving approach of the business school during the pandemic. KPTA focuses more on appreciative dialogue and also helps to replicate the best from other situations to the problem areas. SAP-LAP method also helps practitioners to initiate the right new actions with targeted performance. Practical implications As a greater number of academic institutions impart entrepreneurship education today, the findings of the study would be relevant to the stakeholders, including students, educators and institutes. Social implications The study underpins the importance of the emotional well-being of entrepreneurs/student entrepreneurs and an innovative approach to keep the student moral high during such a challenging situation. Originality/value It is an ongoing exercise at a business school where the challenges were identified, analyzed and solutions were implemented using a structured methodology such as focused group discussions, KPTA and SAPLAP. The innovative initiatives not only engaged the student well but also were able to ensure their emotional well-being.
