THE DEVELOPMENT OF LIVEWORKSHEET-ASSISTED PROBLEM BASED LEARNING TEACHING MATERIALS TO IMPROVE STUDENTS' LEARNING OUTCOMES ON SOCIAL ARITHMETIC

ABSTRACT


INTRODUCTION
The 21st century is centered on the development of the Industrial Revolution Era 4.0 which prioritizes knowledge and technology.However, knowledge alone is not enough to realize the Industrial Revolution Era 4.0, there needs to be a balance between knowledge and skills as the basis of quality human resources.The world of education has also begun to apply various technological advances to support more efficient learning, including by utilizing technology for distance learning, and so on (Negeri, 2021).
Mathematics is one of the compulsory subjects for students in elementary to secondary school (Roza et al., 2019).The process of learning mathematics is used to train human thinking skills in the process of solving mathematical problems, including through the use of ideas or ideas obtained while studying mathematics learned from elementary to higher education (Tunnajach, 2021).
There are many materials in mathematics learning related to everyday life, one of which is social arithmetic material where the material studies the value of an item, sales price, purchase, percentage of profit and loss, taxes and so on.Social arithmetic material is one branch of mathematics whose use is very close to complex problems in social life so it is necessary to show students the meaning of the social arithmetic material studied (Friantini et al., 2020) However, in reality in the field, based on the results of Hasanah's research (2022), student learning outcomes for social arithmetic material are still low.According to research Marlina et al., (2021) in social arithmetic material, many involve story problems in its presentation, this makes many students have difficulty solving the problems presented.
One way to overcome this is to use teaching materials in the form of the right student worksheets.The use of LKPD in mathematics learning can encourage students to learn teaching materials alone or together with their friends (Hidayat &;Irawan, 2017).With the creation of LKPD, students are expected to increase learning activities and express their creative ideas both individually and in groups.Therefore, as a learning medium, the role of LKPD is very important in the learning implementation process because it is able to increase student activities in the learning process (Elfina & Sylvia, 2020).
In addition to the use of LKPD in learning, to help achieve learning objectives, they must use teaching methods or models that are in accordance with the problems faced (Wulandari et al., 2019), one of which is by using a problem-based learning model.According to Sulistyani & Retnawati (2015), problem-based learning is an innovation in 21st century learning, because in this learning the thinking ability of students is really optimized through systematic group or team work, so that students can develop their thinking skills continuously.
According to Widyastuti & Eliyen (2022), to create interesting teaching and learning activities is to create facilities so that students have high interest, one of which is to create learning media that implements information technology, namely a web-based system, because it can be accessed and used by everyone.One of them can take advantage of Live Worksheet webassisted technology According to Fitriani et al., (2021) Live worksheet is a media that converts traditional worksheets into interactive and presented online which can be designed for various materials.In the live worksheet there are text, images, animations and videos that make students not easily bored.So that the LKPD developed in this study is web-aided, namely a live worksheet that can be accessed on the live worksheet.com.
Based on the description above, researchers are interested in applying the Problem-based learning approach and web liveworksheet to develop worksheets for students.

Volume 7, No. 1, March 2024 pp 57-66 61 materials used are printed books from the government and the lack of use of technology in the teaching and learning process, Then the learning approach used still uses a conventional approach.This research was conducted in schools that support their facilities and infrastructure but have not been used optimally in the learning process, so the teacher's response to the development of LKPD is very enthusiastic.Likewise, students are very interested in the development of LKPD, because students are more interested in technologybased learning that utilizes devices, laptops and computers.
The stage of LKPD development is design.Where researchers design appropriate products based on the results of observations that have been carried out and make learning tools.In the preparation of media, researchers use Canva media to design an interesting LKPD, because in Canva there are many animations and components that can be used to make this LKPD more interesting.Based on the validation results from validator 2, 80% were obtained for material eligibility, 97% for LKPD display and 73% for language suitability, the total percentage obtained was 87% which was in the Very valid category.Next is the assessment of validator 3 presented in table 5: Based on the results of the questionnaire given to students, it can be seen that the developed LKPD gets a very practical category with different percentages in each aspect of the assessment, namely the aspect of ease of use 91%, the display of LKPD 85%, efficiency 86% and the display on liveworksheet 89%, and the average percentage is 87.75%.There are several inputs from validators 1 and 2 that there needs to be a re-examination of the spelling section that must refer to the EYD, as well as animations that must be in accordance with the learning learned Therefore, validation is carried out again before conducting wide-scale trials.
After the fix, validation is again performed by validators 1,2 and 3.Here are the second validations performed before the wide-scale trial: Based on the validation results from validator 1, 100% was obtained for material feasibility, 94% for LKPD display and 86% for language suitability, the total percentage obtained was 94% which was in the very valid category.Next is the wide-scale trial assessment of validator 2 presented in table 8: Based on the validation results from validator 2, 80% were obtained for material feasibility, 100% for LKPD display and 100% for language suitability, the total percentage obtained was 94% which was in the valid category.Next is a wide-scale trial assessment of validator 3 presented in table 9: Very Good Based on the results of the questionnaire given to students in wide-scale trials, it can be seen that the LKPD developed gets a very practical category with different percentages in each aspect of the assessment, namely the aspect of ease of use 91%, the display of LKPD 83%, efficiency 92% and the display on liveworksheet 90%, and the average percentage of 88.33% there is an increase of 0.58% in wide-scale trials on student response results.

Discussions
This research and development resulted in a mathematical LKPD product with social arithmetic material using a problem based learning approach assisted by live worksheets.The LKPD developed is for grade VII junior high school students through development-based research.The development of LKPD is carried out in stages, the first of which is the define stage.Where researchers make observations about LKPD used in schools and the difficulties faced by teachers.Based on observations reinforced by interviews, it shows that it is necessary to develop a more attractive and efficient LKPD for students.This is in line with Haryonik & Bhakti's (2018) research that LKPD used by teachers and students in schools is one of the things that needs to be improved and developed.
In the next stage, namely the design of compiling product designs, starting from the preparation of learning tools and test instruments with reference to KD and GPA, continued by compiling the following framework with designs made first in the Canva application by presenting interesting animated images and videos so as to increase student interest and enthusiasm for learning.This is in line with Alfansyur & Mariyani's (2019) research that the colors and sounds that awaken students' enthusiasm for learning.LKPD is made using the PBL learning model on social arithmetic material.The use of media that researchers use is web live worksheets, media selection has been adjusted to learning conditions.
After the next design stage goes to the development stage, before being distributed to students, the product developed needs to know its validity.This validation aims to determine the feasibility of the developed LKPD.In line with Simbolon et al., (2023) Validation is carried out to produce decent teaching materials so that they can be tested on students.The validation of this research was carried out by IKIP Siliwangi Mathematics lecturers and mathematics teachers in schools according to their fields and ability criteria.After the LKPD is validated and uploaded on the web live worksheets, researchers will share the LKPD link with students which will later be accessed via Android or other devices that are connected to the internet.Furthermore, small-scale trials will be carried out for 5 students.In this trial stage, researchers provided questionnaires of student responses to LKPD.When learning, students are very enthusiastic about using LKPD assisted by liveworksheet because this LKPD is a new thing for them.Furthermore, researchers conducted a wide-scale trial, researchers gave questionnaires of student responses to LKPD to 30 students.

CONCLUSION
Based on the results of the analysis and discussion, it can be concluded that an LKPD assisted by Liveworksheet shows very feasible and very practical criteria.This shows that the developed LKPD is very well used for the learning process in the classroom
