Algoritma Umum Pencarian Informasi dalam Sistem Temu Kembali Informasi Berbasis Metode Vektorisasi Kata dan Dokumen

Information retrieval (IR) system is a system, which is used to search and retrieve information relevant to the users’ needs. IR system retrieves and displays documents that are relevant to the users’ input (query). The information retrieval system has several steps and must execute the steps in order to obtain query results. The steps consist of two processes. The first one is processing query and the second one is processing the document collection. Processing query includes: conduct text operation, query formulation, and make terms index for query. Processing the document collection includes: conduct text operation, indexing, and make collection index for document collection. Obtaining terms index and collection index, we are able to process terms index and collection index to obtain ranking results. To obtain ranking results requires knowledge from basic linear algebra. This paper also explores how to make ranking from the most relevant documents to the most irrelevant documents

Transformation of multiple representation in real world physics problem solving

Multiple representation (MR) refers to the use of more than one way of representing ideas, concepts, and processes such as pictorial, graphical, numerical, oral and table. Studies in physics education also found that using MR increases achievement of problem solving among students when more emphasis was placed on qualitative representation. However, students often fail to exploit the advantages of MR or are difficult to transform between MR. In this study, the transformation of MR (TMR) carried out by the secondary school students in real-world physics problems was studied. The Think-Aloud Protocol (TAP) and retrospective semi structured interview (ProTRet) were used to provide more information about how the students use TMR in solving real-world problems. The analysis was qualitative in nature, focusing mainly on the process of the TMRs employed as well as the underlying reasons for their applications. The research data was analysed using constant comparative method (CCM) including open coding axial, coding and selected coding that generates a concept. It was found that there were three types of TMR created by the participants at the early stage of problem-solving, which could be used as an evaluation guide for process monitoring

A critical analysis of COVID-19 research literature: Text mining approach

Objective: Among the stakeholders of COVID-19 research, clinicians particularly experience difficulty keeping up with the deluge of SARS-CoV-2 literature while performing their much needed clinical duties. By revealing major topics, this study proposes a text-mining approach as an alternative to navigating large volumes of COVID-19 literature. Materials and methods: We obtained 85,268 references from the NIH COVID-19 Portfolio as of November 21. After the exclusion based on inadequate abstracts, 65,262 articles remained in the final corpus. We utilized natural language processing to curate and generate the term list. We applied topic modeling analyses and multiple correspondence analyses to reveal the major topics and the associations among topics, journal countries, and publication sources. Results: In our text mining analyses of NIH’s COVID-19 Portfolio, we discovered two sets of eleven major research topics by analyzing abstracts and titles of the articles separately. The eleven major areas of COVID-19 research based on abstracts included the following topics: 1) Public Health, 2) Patient Care & Outcomes, 3) Epidemiologic Modeling, 4) Diagnosis and Complications, 5) Mechanism of Disease, 6) Health System Response, 7) Pandemic Control, 8) Protection/Prevention, 9) Mental/Behavioral Health, 10) Detection/Testing, 11) Treatment Options. Further analyses revealed that five (2,3,4,5, and 9) of the eleven abstract-based topics showed a significant correlation (ranked from moderate to weak) with title-based topics. Conclusion: By offering up the more dynamic, scalable, and responsive categorization of published literature, our study provides valuable insights to the stakeholders of COVID-19 research, particularly clinicians.3417985

The effect of interactive computer animation and simulation on students’ achievement and motivation in learning electrochemistry

Electrochemistry is difficult to learn due to its abstract concepts involving macroscopic, microscopic, and symbolic representation levels. Studies have shown that students can visualize and improve their understanding of chemistry by using interactive computer animation and simulation. This study reports the effect of interactive computer animation and simulation module named “Interactive Electrolysis of Aqueous Solution” (IEAS) developed to aid students in learning electrolysis. A pre and post-test control quasi-experimental design was carried out to investigate the effects of the IEAS on students’ achievement and motivation in electrochemistry topics. This study involved 62 16-years-old male students from two different secondary schools. Pre and post electrochemistry achievement tests (EAT) and pre and post-Instructional Material Motivation Surveys (IMMS) were used. For EAT, using one-way ANOVA, it shows that there was a significant difference in the post-test mean score in this study on the understanding of the electrolysis concept between students in the treatment and control groups [F (1, 60) = 5.15, p <0.05]. The qualitative results also provided evidence that the students in the treatment group had a better conceptual understanding than the control group, especially at the microscopic representation level. For the IMMS test, there was a significant difference between the treatment and control groups in terms of the mean score of the post motivation IMMS test where p <0.05 in chemistry learning [F (1,59) = 266.89, p <0.05]. Thus, it can be concluded that IEAS has an impact on enhancing the students’ understanding of the electrolysis concept, and the students are more motivated to learn electrochemistry

Item analysis on the effects of study visit programme in cultivating students' soft skills: A case study

Experiential learning programme is an important platform in the process of cultivating student's self-development. The teaching ap-proaches that apply experiential learning are widely implemented in higher education. The Faculty of Education in UTM has organised many of such experiential learning activities for students, however the effect of the programmes towards students' self-development is still under researched. Hence, it is still unable to fully identify their effects on cultivating students' soft skills through the process of or-ganizing the programme and students' participations. Therefore, this study was conducted to identify the effects of experiential learning programme namely UNESA Study Visit Programme of the State University of Surabaya (UNESA) organized by the Faculty of Educa-tion UTM towards developing participants' soft skills. This case study involved 39 masters students currently majoring in Primary School Education at State University of Surabaya. The data were collected through a questionnaire involving 20 items which consist of 7 soft skills constructs. Item analysis using the Rasch Measurement Model shows that the most dominant effect is from the aspect of critical thinking and problem solving skills (logit = -1.335). Meanwhile, the positive effect is also reflected in the aspects of Professional Ethics and Moral (logit = -0.495), Communication Skills (logit = -0.410), Lifelong Learning and Information Management (logit = -0.058), Leadership Skills (logit = 0.080) and Team working Skills (logit = 0.435). Lastly, the effect on Entrepreneurship Skills is weaker with logit value = 1.440. The findings show that experiential learning programmes do provide positive effect to students and should be con-ducted more widely in education
