Improving Problem Resolve Skill and Science Learning Result with Creating Worksheet Based on STEM

The occurring problem, student worksheets have not been created truly in the learning process student worksheets used in the learning process only comes from. The student worksheets are not interactive, so that they have an impact on low learning outcomes and ability to solve science problems for fourth grade students at SDN 05 Binanga Dua. This research includes development research. This development research uses ADDIE development. The results of the development show that the manufacturing process produces the student worksheets on the STEM approach for grade IV students with a quality and valid. The results showed that the validation results of student worksheets feasibility test were based on the assessment of the three validators, namely the validation results of learning material experts of 88.23% with a very feasible classification, the validation results of linguists of 83.03% with a very feasible classification, the results of the presentation design expert validation of 93.75% with very decent qualifications. Furthermore, a feasibility test was carried out in small groups to obtain a data percentage of 84.6% and the trial was carried out again in the large group with a percentage result of 89.25% as a reinforcement of the feasibility assessment carried out by the homeroom teacher with a percentage result of 90%. So based on the validity of the student worksheets product, it shows very valid results which show that the student worksheets product is very feasible to be applied in learning activities.

still low, this is shown in the daily tests for the even semester of the 2022/2023 academic year where some students have not reached the minimum standard of completion criteria.The specified minimum completeness criteria of science subject score limit is 7.However, 13 of the 22 students have not yet completed their learning result.The 13 students still had learning outcomes ≥ 70.However, in reality there were still many students who got the under minimum completeness criteria score in science subject.The results of the learning process are realized in student learning achievement which is measured by the grades obtained by students after working on questions given by the teacher at the time the evaluation is carried out (Crosbi, &. H., 2000).
Based on a meta-analysis survey conducted by the World Economic Forum 2015 on elementary and middle school students, 16 abilities were produced that were needed in the 21st century.These sixteen abilities were divided into three categories, namely basic literacy skills and competencies and personality quality.The competency category bunch comprises of 4 capacities, specifically basic considering and problem-solving, innovating, communicating and collaborating.Issue understanding capacity is one of the most aptitudes that understudies must have.Separated from the study from Joynes, C., Rossignoli, S., & Fenyiwa Amonoo-Kuofi, E. ( 2019) the Consortium for Evaluation and Instructing of 21st Century Abilities (AT21CS) moreover gotten the same discoveries.The significance of having the capacity to unravel issues as an expertise to confront this competitive period requires instructors and schools to alter learning designs.Creating issue understanding capacities must begin from changing the student's part in learning from a detached learner to a dynamic learner.
The reality that happens within the field is that students' capacity to reply to questions with reasons, inquire questions when they do not get it the fabric is still missing, as well as when understudies are inquired to analyze a issue, conclude issues, and talk about issues that are still missing.This fact supports the researchers' initial findings which found that only around 47.8% of elementary school students at SDN 05 Binanga Dua class IV still had not achieved the minimum completeness criteria score (≥70) in the previous semester's science exam.Students still experience difficulties in determining and solving the problems they experience related to science learning material.This can be since there are still numerous understudies who as it were memorize concepts and are less able to utilize these concepts in case they experience issues in their lives related to the concepts they have, understudies are indeed less able to decide issues and define them (Trianto, 2009;Wijayanti, A, 2018).
Educating materials play an imperative part in guaranteeing the viability of educating and learning exercises, one of which is understudy worksheets (Pertiwi, J W., Solfarina., & Langitasar, I. 2021).In this manner, it is regarded essential to create understudy worksheets that's adjusted to the conditions and needs of understudies.In an exertion to create problemsolving capacities, instruction nowadays ought to lead to a learning handle that emphasizes natural problems.The arrangement that's considered fitting to overcome the issue over is to utilize an suitable learning approach and educating materials so as to energize understudies to create a logical demeanor in basic considering.This STEM approach is an approach that alludes to the four components of science, specifically information, innovation, designing and arithmetic.The STEM approach is an integration of science, technology, designing, and arithmetic learning that's suggested to cultivate victory in 21st century aptitudes.(Brown, et al, 2011;Pertiwi, J W., Solfarina., & Langitasar, I. 2021;Irfana, S., D, Y., & Wijayanto, 2018).The STEM learning approach gives openings for instructors to appear understudies that concepts, standards, science, innovation, engineering and arithmetic are utilized coordinating way within the improvement of items, forms and frameworks utilized in their everyday lives (Zamista, A. A., 2018).
