Abstract

[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.

Abstract

Utilization of technology, information and communication, especially the use of software such as Microsoft Word, Microsoft Power Point and Microsoft Excel is an ability that must be possessed by elementary school teachers in implementing an independent curriculum. The use of Microsoft Excel, for example, can assist teachers in processing various data, such as processing assessment instruments in the form of end-of-semester assessment questions for students. Based on interviews with the group leader V Lingsar, the results showed that teachers still needed time in making final semester assessment questions, starting from making question banks, sorting and randomizing questions into several question packages. To answer these problems, a service activity was carried out in the form of training on the use of Microsoft Excel to create a question bank. The training was attended by 20 teachers of the V Lingsar group. This activity consists of two sessions, namely the delivery of material and guided practice. All participants felt that the material could be understood well, guided practice could be carried out smoothly and this activity could be relevant to the needs of the teacher.
