A pedagogical framework for enhancing skills of references and citations

References and citations form a basis for scientific research and creation/discovery of knowledge. However literature reviews had indicated that many errors are present in scholarly papers published in journals and conferences as well as in books and articles. Furthermore, course works of students studying in higher education institutions contain mistakes in references lists and in-text citations. Problems that stem from these inaccuracies are multifarious and range from the act of plagiarism, not acknowledging the source, problems in information access and retrieval as well as causing inaccuracies in ranking articles and journals, thus hindering the growth of knowledge. Based on the importance of this global issue this research was initiated. The first objective of our research was to determine root causes for the presence of mistakes and inadequacies in references and citations within the academic arena. We chose the academic arena because they are the training grounds for education and scientific research. Furthermore, through this research we sought a unique practical solution for this issue. In order to conduct a thorough and comprehensive investigation into the above mentioned problems, and to achieve the aim of proposing a suitable solution, we divided our research work into three main phases. First phase was the investigative phase. During this phase a thorough literature review was conducted. As a result of this review, research questions were formed. Both quantitative and qualitative methods were adopted to investigate the causes of erroneous references and citations. Triangulation research methodology was used to get reliable and comprehensive information. Data received through these methods were analyzed and core issues such as inadequate feedback and training in referencing task were highlighted. In the second phase, termed as solution phase, a pedagogical framework was proposed to resolve issues that were reported during the investigative phase. A conceptual framework was built on the principles of Learning theories and spaced repetition theory. To evaluate this framework experiments were conducted. This was done in the third and final phase of the research which was termed as evaluation phase. Two types of experiments were conducted, first type was in a traditional classroom environment and the second type of experiment was with students who chose to work independently (without tutors). Data were collected and analyzed from these experiments using both quantitative methods and qualitative methods and were analyzed. This research provides insight into causes of errors within referencing tasks of students in higher education. It Indicates that reform in the pedagogy for teaching this skill is needed. Furthermore a unique pedagogy is presented. Results from experiments have indicated that through the proposed operational model improvements of referencing skills have been seen

Towards a circular economy: fabrication and characterization of biodegradable plates from sugarcane waste

Bagasse pulp is a promising material to produce biodegradable plates. Bagasse is the fibrous residue that remains after sugarcane stalks are crushed to extract their juice. It is a renewable resource and is widely available in many countries, making it an attractive alternative to traditional plastic plates. Recent research has shown that biodegradable plates made from Bagasse pulp have several advantages over traditional plastic plates. For example, they are more environmentally friendly because they are made from renewable resources and can be composted after use. Additionally, they are safer for human health because they do not contain harmful chemicals that can leach into food. The production process for Bagasse pulp plates is also relatively simple and cost-effective. Bagasse is first collected and then processed to remove impurities and extract the pulp. The pulp is then molded into the desired shape and dried to form a sturdy plate. Overall, biodegradable plates made from Bagasse pulp are a promising alternative to traditional plastic plates. They are environmentally friendly, safe for human health, and cost-effective to produce. As such, they have the potential to play an important role in reducing plastic waste and promoting sustainable practices. Over the years, the world was not paying strict attention to the impact of rapid growth in plastic use. As a result, uncontrollable volumes of plastic garbage have been released into the environment. Half of all plastic garbage generated worldwide is made up of packaging materials. The purpose of this article is to offer an alternative by creating bioplastic goods that can be produced in various shapes and sizes across various sectors, including food packaging, single-use tableware, and crafts. Products made from bagasse help address the issue of plastic pollution. To find the optimum option for creating bagasse-based biodegradable dinnerware in Egypt and throughout the world, researchers tested various scenarios. The findings show that bagasse pulp may replace plastics in biodegradable packaging. As a result of this value-added utilization of natural fibers, less waste and less of it ends up in landfills. The practical significance of this study is to help advance low-carbon economic solutions and to produce secure bioplastic materials that can replace Styrofoam in tableware and food packaging production
