{"title":"Investigating Factors Contributing to Poor Performance in Teaching and Learning of N3 Assembly Drawing: A Case of uMgungundlovu TVET College","authors":"Philani Brian Mlambo, Mthokozisi Sakhile Mkhwanazi","doi":"10.36312/esaintika.v8i1.1479","DOIUrl":"https://doi.org/10.36312/esaintika.v8i1.1479","url":null,"abstract":"Poor performance in Assembly Drawing (AD) has been a significant issue in Engineering Graphics and Design (EGD) in high schools and TVET colleges. This poor performance in AD, which is a crucial component of the EGD exam, leads to students not performing well in Grade 12 and consequently limits their entry into engineering programs in TVET colleges. Consequently, this study aims to investigate the contributing factors to poor performance in the teaching and learning of AD among N3 students. To achieve the objectives of this study, a mixed research approach was employed, and data was collected through semi-structured interviews and the Purdue Spatial Visualization Test (PSVT). A purposive sampling method was used to select four Engineering Drawing (ED) lecturers and 45 N3 Engineering Drawing students to participate in this study. Furthermore, Piaget's perception and imagery theory and Pedagogical Content Knowledge (PCK) were utilized as frameworks underpinning this study. The interview results were analyzed using thematic analysis, while the data from the PSVT was analyzed using the Statistical Package for Social Sciences (SPSS). The findings of this study indicate that N3 students have very low spatial visualization skills, and the negative attitude displayed by both students and lecturers towards the teaching and learning of AD contributes to poor performance in N3 ED. The findings further revealed that the lack of drawing-related teaching qualifications among lecturers also contributes to poor performance in AD. Furthermore, the quantitative findings show that the students achieved a mean score of 16.82, with a standard deviation of 8.389, indicating poor performance on the PSVT test. One limitation of this study is the small number of lecturers interviewed (four), which makes it difficult to generalize the results. Therefore, future studies should include a larger sample size of lecturers. This study recommends that lecturers be hired based on their relevant teaching qualifications and further suggests the use of technology to enhance students' spatial visualization skills and improve their performance in AD.","PeriodicalId":165148,"journal":{"name":"Jurnal Penelitian dan Pengkajian Ilmu Pendidikan: e-Saintika","volume":"96 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140495769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the proposed process, the main product from the reaction is biodiesel, whereas the by-products consist of glycerol and fertilizer. Biodiesel is mainly used in automotive diesel engines for various reasons, such as having a greater oxygen content, a higher cetane number, a higher viscosity, a lower aromatic content, and very little sulfur. These properties are essential in engine performance, combustion, and emissions. This review provides a comprehensive analysis of recent literature on biodiesel production methods from waste cooking oil, where the methods are grouped systematically and assessed. A decision table on process selection is provided to screen the most suitable technology for biodiesel production from waste cooking oil.

Initial symptoms of damage to host plants are marked by the appearance of black spots until the plant parts rot and fall. Fruit flies will inject their eggs until they hatch and become larvae, then the larvae will gnaw the fruit flesh from the inside. Control of fruit flies so far still uses factory chemical insecticides that are not environmentally friendly and leave residues that threaten health. Controlling fruit flies that are environmentally friendly and not at risk of leaving residue can use attractants made from natural ingredients. This study was aimed to determine the effectiveness of the use of natural-based attractants that utilize local raw materials on the allure of fruit fly insects. The materials used in this study were clove leaves, lemongrass leaves, guava leaves, pandan leaves, lime leaves, pineapple and star fruit. The tools used to trap insects use two tools, namely trap bottles and glue. The results showed that the use of lemongrass leaves, clove leaves, guava leaves and pineapple fruit was quite effective in trapping fruit fly pests. Lemongrass leaves more effective than others (27 results in a week). A more effective tool to use is fly glue. The most effective combination is glue with clove leaves, guava leaves, and pineapple (number of results is >100 in a week).","PeriodicalId":165148,"journal":{"name":"Jurnal Penelitian dan Pengkajian Ilmu Pendidikan: e-Saintika","volume":"186 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115800408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically, the assessment of the quality of learning implementation involves observation by multiple raters. This study aims to provide construct validity evidence and estimate the reliability of performance assessment instruments for educators in higher education. 225 second-year and third-year students from the Faculty of Education participated as raters, evaluating the performance of educators in their teaching practices. Forty assessment items were used to evaluate the performance of 19 instructors. Exploratory Factor Analysis (EFA) and Generalizability Theory (G-Theory) were employed to examine the quality of the performance assessment instruments. The EFA analysis resulted in the identification of five factors that contribute to educators' performance in teaching: (1) readiness and planning, (2) pedagogy and professionalism, (3) personality, (4) social relationships within the classroom, and (5) social relationships beyond the classroom, collectively explaining 67.671% of the variance. Of the 40 assessment items, 37 demonstrated construct validity, while three required revisions. These findings indicate the alignment between the instrument's factors and the formulated theory of teaching competence. The reliability of the measurements was estimated using G-Theory in RStudio, yielding a relative G coefficient of 0.88 for three raters. The D-Study results indicated that the instrument could be used to assess performance, with an estimated generalizability coefficient of 0.738, requiring a minimum of five raters for each person (educator) being evaluated. We recommend employing G-Study and D-Study to determine the number of raters involved in performance assessment as a means of cost and time efficiency in the evaluation process.","PeriodicalId":165148,"journal":{"name":"Jurnal Penelitian dan Pengkajian Ilmu Pendidikan: e-Saintika","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125530527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It typically exists as complex organic substances generated in the natural water ecosystem as part of hydrologic, biological, and geological cycles. The significant variation, composition, and abundance of NOM in natural water or wastewater necessitate the implementation of robust and adaptive technologies, particularly in addressing even more stringent standards of drinking water supply or treated water discharge. Coagulation is one of the most common processes for water and wastewater treatments. It is highly desirable to treat feed containing NOM because it prevents the disinfection of by-products formation. Therefore, current dynamics of NOM in terms of varying compositions and concentrations demand improvement in handling the coagulation process through optimization of operational parameters (dosing and the control of pH), application of novel and more effective coagulants, and as a combination with other processes through process intensification. This review provides a comprehensive analysis of recent literature on developments of coagulation for NOM removal. The coagulants are grouped systematically and assessed. Next, enhanced coagulation via process intensification with other processes (membrane filtration, oxidation, adsorption, and ion exchange) is discussed. Lastly, the future outlook on research direction on sustainable coagulation process is listed to support circular and bioeconomy.","PeriodicalId":165148,"journal":{"name":"Jurnal Penelitian dan Pengkajian Ilmu Pendidikan: e-Saintika","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134053084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
