Authentic Assessment for Academic Performance; Study on the Attitudes, Skills, and Knowledge of Grade 8 Mathematics Students

The purpose of this research is: (1) To know the quality of the mathematics learning outcomes that apply an authentic assessment, (2) To know the student's response to the application of an authentic assessment of mathematics learning. This study uses a quantitative method of a causal-comparative type, using test instruments, questionnaires, and observations. The object of this study is conditioned in 2 classes, control class (Class 8B) and experiment class (Class 8E). The results showed that the application of the authentic assessment used by teachers is good. On the basis of the data obtained, it is known that the result of learning two classes (control class and experiment class) on attitudinal aspects and skills has the same relative quality. While the learning outcomes on the knowledge aspect, the maximum value reached by the experimental class is higher than the control class (from 72.5 to 65). The effect of treatment on the experimental class is low, indicated by the value of ES (effect size) obtained equal to 0.3. The result of the study based on the student's response level shows that there are 7 students who have a low response to the learning activity (18%), 23 students have an average response to the learning activities (61%) and 8 students have a high response to learning activities. Two other categories, none of the students had very low and very high responses to learning activities (0%). This study also confirmed that Ho was rejected and Ha was accepted so it can be concluded that there are differences in mathematics learning outcomes among students who use authentic assessment with students who do not use authentic assessment.

PENGGUNAAN BAHAN AJAR BERBASIS MULTIMEDIA INTERAKTIF TERHADAP HASIL BELAJAR MATEMATIKA SISWA

Mathematics is a lesson that most students do not like. This, resulting in low mathematical learning outcomes. Therefore, in order to optimize the results of learning mathematics is required interactive and innovative teaching materials. The utilization of teaching materials based on interactive multimedia is an alternative solution that is needed to the problem. So the purpose of this study is to analyze the influence of the use of interactive multimedia-based teaching materials to the results of learning mathematics. The measured mathematical learning results include affective, psychomotor and cognitive spheres. The method used in this study is a qualitative research design with One-Group Pretest-Posttest Design. The study population used class VII in MTsN 8 Losari. With class study sample VII A by random sampling. Data collection was done before and after being treated which was obtained through math test, then analyzed using linear regression test. it was found that interactive multimedia usage response was in a good category with 74% percentage. In the affective domain is in the good category with a percentage of 74%. While in the psychomotor realm is in a good category by obtaining 77.5% percentage. In addition, the results of pretest (33.22) and posttest (85.84) averaged, then an increase of 44%. When viewed from hypothesis test by using regression test; 1) ineffective learning result, interactive multimedia influence 15,5%, 2) learning result of the psychomotor domain, multimedia affects 15,8%, and 3) in multimedia cognitive domain influence 11,4%. This shows that there is the influence of interactive multimedia usage to the three aspects of student learning result of mathematics
