The Effect of Online Project-Based Learning Application on Mathematics Students' Visual Thinking Continuum in Covid-19 Pandemic

Abstract

The COVID-19 pandemic led to the implementation of the Work From Home<strong> </strong>(WFH) policy. The impact of this policy is to replace the process of teaching and learning activities by using an online learning system. In this industrial era 4.0, the integration of web applications is very much needed in problem-solving learning. One that can be used to integrate web applications in learning through project-based learning. The focus of this research is to study the effects of online project-based learning applications on mathematics students' visual thinking continuum. Instruments used in the form of rubric virtual mind maps, audio-visual and virtual posters are used to observe students' visual thinking continuum. The instrument was analyzed with the Rasch measurement model software named WINSTEPS. This study used one group pretest-posttest design to see the effect of integrating web applications in learning through project-based learning analyzed using SPSS. The results of instrument analysis for rubric virtual mind maps, audio-visual products, and virtual posters on measure person obtained good person reliability, MNSQ infit, and MNSQ OUTFIT the average rating is very good. For the ZSTD infit and the ZSTD outfit, the average value is close to 0.0 so that the quality of the person's reliability is good. The results of the conformity quality of the items with the model studied from the fit order items obtained the value of Outfit mean square (MNSQ), Outfit Z-standard (ZSTD), and the value of Point Measure Correlation (Pt Mean Corr) for the three instruments met good criteria. The results of the analysis of paired samples test from 54 respondents obtained p <0.05 so that the base learning project has the effect of increasing students' visual thinking continuum. Implementation of online project-based learning in mathematics learning is an alternative that can be used to improve students' creative problem-solving skills in online learning

Mobile Application to Detect Covid-19 Pandemic by Using Classification Techniques: Proposed System

“…Antibody studies, on the other hand, use blood samples to determine the immunity induced by the previous infection. Antibody test kits look for proteins that the virus uses as "glue" to trap antibodies in the blood [30][31][32].…”

Students’ Performance and Perceptions Towards Authentic Learning Environment Based on Visual Thinking Continuum

“…However, a study by [37,28] on the use of visual learning led to the development of a continuum of visual thinking, such that when students make use of and interact with the visual tools provided by a learning system, their visual thinking and learning skills increased profoundly from visual thinking to visual learning elements, and eventually to the highest element known as visual communication. Elements of visual thinking include use of pictures, colors, diagrams or other visual media as well as animation and simulation human utilize visual thinking to imagine or conceptualize problems, or rather visualize the reality within a certain boundary of limitation [3,28].…”

“…The use of visuals from a computer logic perspective applied in this learning website is based on a proposal by [30]. According to [37,28] the continuous provision of visual materials for learning will promote students' better understanding of concepts. In addition, it helps to stimulate students' continuum development that improves from visual thinking to visual learning, and eventually to the highest-level i.e.…”

Analysis on the Actions of a Continuous Distance Training Session for Teachers and its Impact on Their Actual Practices

“…The Note which appeared on August 28, 2020, to organize teaching during the 2020-2021 school year, posed numerous challenges; At the time, it was necessary to fill the learning deficit of the previous year imposed by the Covid-19 and to optimize the learning time devoted to the students (who attended just half of the classroom sessions under normal teaching conditions) to complete the annual program on time. This required improved methods of learning in a short time and needed more commitment and technical-pedagogical skills of teachers to adopt teaching oriented towards the learner, thus promoting their participation in the construction of knowledge [64] as well as the involvement of all parties (ministry, parents of pupils, pupils, associations, etc. ).…”
