“…The effect of heuristic strategy on creativity ability is 48.0%. This is consistent with the results of the study that learning strategies can improve mathematical creative thinking skills (Nanang, 2016;Sormin, 2016;Rahmazatullaili, 2017;Rochani, 2016). The effect of heuristic strategy on mathematical communication ability is 62.5%.…”

The purpose of this study is to determine the impact of heuristic strategy on students' mathematical abilities in high order thinking. This descriptive research uses a correlation design. The population of this study were all second-grade public and private high school students representing schools from eight districts in North Sumatra province, and samples (N = 257) were taken randomly. Based on linear regression analysis through analysis of variance (ANOVA) results obtained that heuristic strategy has a very strong influence on students 'mathematical abilities in high order thinking, and partially heuristic strategies affect students' ability in (1) understanding of concepts, (2) creativity, (3) mathematical communication, (4) problem solving, and (5) reasoning ability.

“…Problem solving constitutes an exercise for students to deal with non-routine problems and try to solve them followingly (Simamora & Saragih, 2019). Problem solving ability is necessarily needed in solving various problems, so students need to be trained to solve problems that provide opportunities to explore their ability in order to put forward ideas or strategies in solving the problems (Rahmazatullaili, Zubainur, & Munzir, 2017;Pimta, Tayraukham, & Nuangchalerm, 2009). Strategies in solving problems related to mathematical problems are called heuristics because in learning mathematics, basically, students must be able to find their own knowledge (Guven & Cabakcor, 2013;Shoimin, 2014).…”

[English]: This study aims to determine the level of lower secondary school students’ ability in solving mathematical word problems and how much both mathematical modelling ability and verbal ability influence the ability to solve word problems in the implementation of Kurikulum 2013 (Curriculum 2013). This study involved 411 students as samples determined by stratified proportional random sampling technique. The test used was declared valid through construct validity and reliability with Cronbach's alpha. Data were analyzed descriptively and inferentially. Descriptively, the students' ability in solving mathematical word problems was classified as medium. Meanwhile, inferentially, results were obtained indicating that: (1) students' verbal ability is significantly influential on the ability to solve word problems by 47.6%; (2) the students’ ability in mathematical modelling is significantly influential on the ability to solve word problems by 84.6%; and (3) students' verbal and mathematical modelling abilities are significantly influential on the ability to solve word problems by 87.8%. This indicates that the increase in students' ability to solve mathematical word problems will be more optimal if the verbal ability and the mathematical modelling ability are considered simultaneously, rather than focusing on one ability only. Keywords: Verbal ability, Mathematical modelling, word problems, Curriculum 2013 [Bahasa]: Penelitian ini bertujuan menentukan tingkat kemampuan siswa SMP menyelesaikan soal cerita matematika dan seberapa besar pengaruh kemampuan membuat model matematika dan verbal terhadap kemampuan menyelesaikan soal cerita pada pelaksaaan kurikulum 2013. Penelitian ini melibatkan 411 siswa sebagai sampel yang ditentukan melalui teknik stratified porposional random sampling. Tes yang digunakan dinyatakan valid melalui uji validitas konstruk dan reliabel dengan Alpha Cronbach. Data dianalisis secara deskriptif dan inferensial. Secara deskriptif, kemampuan siswa dalam menyelesaikan soal cerita matematika masih tergolong sedang. Sedangkan secara inferensial diperoleh hasil bahwa (1) kemampuan verbal siswa berpengaruh secara signifikan terhadap kemampuan menyelesaikan soal cerita, dengan kemampuan verbal 47,6%; 2) kemampuan siswa dalam membuat model matematika berpengaruh secara signifikan terhadap kemampuan menyelesaikan soal cerita, dengan kemampuan membuat model matematika 84,6%; 3) kemampuan verbal dan membuat model matematika siswa berpengaruh secara signifikan terhadap kemampuan menyelesaikan soal cerita, dengan kemampuan verbal dan membuat model matematika sebesar 87,8%. Hal ini mengindikasikan bahwa peningkatan kemampuan siswa dalam menyelesaikan soal cerita matematika akan lebih optimal jika kemampuan verbal dan kemampuan membuat model matematika diperhatikan secara bersamaan dibandingkan hanya fokus pada salah satu kemampuan saja.

“…2017). Activities in learning through problems that are packaged in the form of project work also provide an interesting learning experience, have a significant effect on the achievement of learning outcomes and are able to improve student's thinking skills in solving problems (Rahmazatullaili, et al 2017;Rahardjanto, et al 2019). In integrated science learning, the PjBL strategy is able to improve learning outcomes, understanding and applying the concept of developing integrated science learning media Safaruddin, Ibrahim, et al, 2020).…”

This research is to precieve the learning outcomes and student responses to the applied models and applications. The type of research carried out was experimental research using a one group pretest-posttest design with the research subjects were 29 students of the fifth semester of 2019/2020 academic year who took Capita Selecta Chemistry Course. The data collection technique was carried out by means of test techniques, namely learning outcomes as seen from the pretest and posttest scores, as well as non-test techniques as seen from observation, interview and student response questionnaires to the application used via google form. The t test was carried out with the help of the SPSS 23 program. Based on the research conducted, there was an increase in student learning outcomes from a value of 65.172 (pretest average score) to 84.586 (posttest average score). The N-Gain score of 0.557 is included in the moderate category, indicating that there is a significant increase in student's critical thinking skills using the PjBL model and the Edmodo application. The results of the student response questionnaire stated that only 48.28% of students liked learning using the online/edmodo application. 51.72% of students still like direct/face-to-face learning. As many as 96.55% of students considered the Edmodo application to provide a new atmosphere in capita selecta lectures. The response to the edmodo application and the project model used was very good. Students are enthusiastic about the edmodo application because it has complete, interesting and easy to learn features. Project Based Learning (PjBL) learning model using the Edmodo application can be recommended to be applied by the lecture.
