Perceptions Of School

A decline in the number of students opting to study science in high school is a matter of international concern, particularly in relation to students who demonstrate high academic ability in science. These high-ability students have the potential to be the innovators and leaders of the future. There is a paucity of research that provides insight into how schools address the motivational and learning needs of high-ability science students. Underpinned by a constructivist view of learning, this exploratory case study research used student questionnaires and focus group interviews to explore students’ views about their learning experiences in science. It investigated high-ability students’ perceptions of how their needs were being met. Findings indicate that these students generally experienced a wide range of teaching approaches across all science disciplines. Learning was mostly limited to science content and procedures with little evidence of students learning about how science works through Nature of Science.

This paper discusses the challenges of records management that arise from the use of adapted buildings as records centres in Zimbabwe, despite the advantages of using such buildings. A qualitative research approach was used as well as a case study research design. Data were collected from seven officers of the Gweru Records Centre through semi-structured interviews. Personal observation was used to triangulate findings from interviews. It was found that the use of adapted buildings as records centres was a cheaper and quicker way of establishing records centres throughout the country. However, a number of preservation, security and management challenges cropped up as the conditions of the buildings and the environment of the adapted buildings were not conducive to the proper and professional management of records. This study is important in that it explores the prospects and challenges of using adapted buildings as records centres in Zimbabwe, an area that has not been researched by many authors. This provokes archival authorities and the government to seriously consider establishing purpose-built records and archival centres.

Abstract Background and Purpose: Motivation of this research is to explore the current trend in automating the business processes through software robots (Robotic Process Automation – RPA) and its managing within enterprise environment where most of the processes are executed by human workforce. As the RPA technology expands the demand for its coordinating grows as well. The possible solution to this challenge is shown in case study research in form of implementing orchestration platform to a concrete business process of onboarding in HR department of a multinational company. The aim of this paper is to explore the phases and activities of the pilot project implementation of Robotic Service Orchestration (RSO) in combination with RPA technology and to assess the potential benefits. Design/Methodology/Approach: Case study research approach was selected to explore the research phenomena, which is the implementation of RSO platform in combination with RPA technology and assessing incoming benefits. The case is formed with 2 companies – (1) multinational company with ongoing effort of automating onboarding process, (2) technology and consulting company delivering the automation solution. Data were collected through semi-structured interviews with respondents from two involved companies and by analysing internal documents. Results: The analysis of case provided in this paper revealed some key insights: (1) strategical position of RSO and tactical position of RPA towards the existing legacy systems, (2) need for increased focus on initial process modelling phase, (3) Application Programming Interface (API) integration is more viable solution for RPA, (4) the biggest benefit of RPA - its agility, (5) future potential of the RSO replacing the BPMS. Conclusions: First of all, there is a need of higher number of software robots adopted in a company before orchestration could pay off. On the other side, current Business Process Management Systems (BPMS) solutions don’t offer functionalities for managing human and software robots workforce altogether. RPA is expected to expand and without proper orchestration the effectivity will not grow constantly.

In its development, madrasas experienced ups and downs in their development. The most basic problem is the management aspect. The following cases of management are interesting to note. There are schools or madrasas that initially experience setbacks, then can progress rapidly. On the other hand, there are schools or madrassas that initially developed, but then almost went out of business. One of the reasons is due to the management that is not mature enough, therefore personnel management in the world of education is very important especially in educational institutions especially Islamic-based educational institutions. This study aims to determine the application of personnel management in Islamic education institutions and supporting and inhibiting factors in its application. This research is a type of field research with a multi-case study research approach. Data collection methods used Participatory Observation and In-depth interviews. The steps of data analysis in this study use the analysis of the Miles and Huberman models.

This paper develops a framework for analyzing organizational change in information technology (IT) departments of state-owned enterprises (SOEs) and applies that framework to a case study of a German airport that is majority-owned by the German federal government. Specifically, we derive a framework from literature to systematically identify transformation barriers for introducing new enterprise resource planning (ERP) systems and business processes in IT departments of SOEs. This framework is based on the punctuated equilibrium model and considers dynamic process incorporation, explicit stakeholder integration, a detailed representation of the change process, and characteristics of public employees as main factors. We then apply the framework in a case study research approach and show how the framework allows identification of transformation barriers hidden to management but involved in the organizational change process (e.g., required change of organizational structures, required change of service-level-agreements). The framework can be a valuable tool for both researchers and practitioners to actively shape the effects of organizational transformation in SOEs and to identify factors that influence the change process.
