Banknotes residues and thermoplastic starch as sustainable reinforcements for LDPE-based agricultural composites
Get PDFThis study examines the development and characterization of composites comprising low-density polyethylene (LDPE), thermoplastic starch (TPS), and cellulose fibers sourced from recycled banknotes (BR). The composites were fabricated using extrusion and injection molding techniques, followed by an evaluation of their morphological, thermal, mechanical, and water absorption properties. The inclusion of BR fibers enhanced the mechanical performance of LDPE, notably improving tensile strength and elastic modulus, while the hydrophobic treatment of the fibers ensured minimal water absorption. The incorporation of TPS increased the composites' biodegradability potential but reduced tensile strength and increased water absorption due to its hydrophilic nature. Scanning electron microscopy revealed strong interfacial adhesion between the fibers and matrix and confirmed the complete dispersion of starch in TPS-containing samples. Thermogravimetric analysis highlighted the thermal stability of the composites and identified distinct degradation stages corresponding to the matrix, TPS, and fibers. These results indicate that the developed composites offer a viable solution for agricultural applications, balancing mechanical performance and environmental sustainability
The relationship between perceived learning, academic performance and academic engagement in virtual education for university students
Get PDFThis study aimed to determine whether the three dimensions of academic engagement (cognitive, emotional and behavioral) were positively associated with perceived learning and academic performance. The participants were 301 university students from Lima. Structural equation models were used to test the proposed theoretical relationship between the variables. The results indicated that the model showed satisfactory fit indices (CFI = 0.956, TLI = 0.949, RMSEA = 0.043, SRMR = 0.062). Perceived learning was found to be predicted by cognitive engagement (β = 0.447, p < 0.01) and emotional engagement (β = 0.230, p < 0.05). However, there was no statistically significant relationship between behavioral engagement and perceived learning (β = 0.035, p = 0.840). On the other hand, academic performance was predicted by behavioral engagement (β = 0.393, p < 0.05) but not by cognitive (β = -0.164, p = 0.301) or emotional (β = 0.001, p = 0.991) engagement. The study highlights the importance of fostering academic engagement in university students to enhance both their academic performance and perceived learning

The effectiveness of science encyclopedia-assisted project-based learning integrated with the STEM approach in enhancing pre-service elementary teachers’ scientific literacy
Get PDFScientific literacy plays a crucial role for elementary teachers in developing the strategies of science learning and implementing them in the classroom. Nevertheless, the scientific literacy of college students in elementary education has not been optimal. Science encyclopedia-assisted project-based learning (PjBL) integrated into the science, technology, engineering and mathematics (STEM) approach is hypothesized to enhance scientific literacy. The present study describes and examines the effectiveness of science encyclopedia-assisted STEM-PjBL in enhancing pre-service elementary teachers’ scientific literacy. Quasi-experimental research using a pre- and post-tests control group design was applied to this study. 56 pre-service elementary teachers at the University of Halu Oleo were involved in this study whereby they were equally distributed to two groups. A test of scientific literacy was adapted and used to measure scientific literacy. Descriptive and inferential statistics were used to describe and analyse the data of scientific literacy. Results revealed that science encyclopedia-assisted STEM-PjBL had a positive modest effect on the achievement of scientific literacy. The scientific literacy of college students in elementary education who received science encyclopedia-assisted STEM-PjBL had moderate enhancement. Additionally, a science encyclopedia-assisted STEM-PjBL significantly enhanced scientific literacy. Educational practitioners can implement a science encyclopedia-assisted PjBL integrated STEM approach to enhance scientific literacy resulting in high achievement in science education

The findings highlight the relevance that teachers believe the design of educational spaces should have in the teaching-learning process. Thus, the results show that there are significant differences with respect to age and professional experience in relation to the teacher's perception of infrastructure. Therefore, it is important to conclude by highlighting the consideration of the educational space as an essential element for the incorporation of methodological renewal in the classroom
Evaluation of the application of the ACEP cycle to student writing learning outcome
Get PDFThe modification of the ACEP cycle is a pedagogical strategy consisting of four components: (A) Activities. (C) Classroom discussion. (E) Exercises. (P) Performance. The application of ACEP cycle modifications is used as a strategy to improve writing skills. This is the primary focus to consider in improving writing skills. The purpose of this study was to evaluate how effective the process of learning writing skills was by applying ACEP cycle modifications. This study used a mixed-methods approach. At the qualitative stage, an explanatory description design strategy is applied to collect comprehensive and in-depth information about the learning model applied by the teacher in the classroom. A pre- and post-test control group design is used in the quantitative stage. The average score of students using the ACEP cycle modification was 82.64, higher than that of students who studied under the demonstration learning model which was 80.03. This finding is reinforced by the result of the significance coefficient = 0.006 < 0.05 so H0 is rejected. Thus, there is a difference in average student learning outcomes between the modification of the ACEP cycle and the demonstration learning model. ACEP cycle modification has practical implications for writing skills. First, it can easily identify the initial condition of students' writing skills. Second, ACEP cycle modification allows teachers to better understand how students build an understanding of writing concepts. Third, students can actively participate in the learning process and fourth, teachers can observe the construction stage and measure student progress more accurately
