Abstract

To many abstract concepts in mathematics learning make students think mathematics is difficult. The purpose of this research is to obtain the effectiveness of Guided Teaching learning with E-learning to improve students mathematical communication skills by 1) students mathematical communication skills who are given Guided Teaching learning with E-Learning achieve minimal mastery of both individual and classical learning, 2 ) students mathematical communication skills are given Guided Teaching learning treatment with E-Learning better than expository learning, and 3) an increase in mathematical communication skills of students who are given Guided Teaching learning treatment with E-Learning better than expository learning. The method used in the experiment (quantitative). Data collection methods using observation, interviews, and tests about students mathematical communication skills. Data analysis uses the completeness test, proportion test, comparative test, and N-Gain test. The results of this study obtain the effectiveness of guided teaching-learning with e-learning as follows (1) individual completeness meets KKM (68), (2) classical completeness by 75% with the proportion of students already getting 68 grades has exceeded 75%; (3) students mathematical communication skills of Guided Teaching learning with e-learning by 80.75 higher than expository learning by 69.50 (4) an increase in students mathematical communication skills of 0.407 medium categories and the difference in the increase in mathematical communication skills of students who were given treatment guided teaching-learning with e-learning is greater than Expository learning.

Abstract

The purpose of this study is to know whether the development of teaching materials gamification for seventh-grade students is feasible and interesting for use in junior high school. The subjects of the experiment were seventh-grade students at SMP Bandar Lampung. This research method is Research and Development (R&D), which a using Borg and Gall development model. The results of the assessment are: the expert assessment of the material giving a scored with an average percentage of 76% is categorized as highly feasible, the media or design experts scored with an average percentage of 71% categorized as feasible and the linguist gave a score with an average percentage of 69% categorized as feasible. In small group trials, an average of 3,6 was obtained with very attractive and feasible categories. In the field trial, it was found that the average of 3,4 was obtained with very attractive and feasible categories and the teachers response to the materials gamifikasi, it was found that the average of 3,3 was obtained with very attractive and feasible categorized. So it can be concluded that the gamification teaching materials on the are categorized very attractive and feasible for use in mathematics learning in junior high school.

Abstract

The purpose of this study is to describe the mathematical communication skills of high school students in terms of guardian and idealist personality types. Subjects in this study were taken using a purposive random sampling technique of two students from class X senior high school in Bandar Lampung with different personality types, that is one student with guardian personality type and one student with a idealist personality type based on David Keirseys personality dimensions, with personality type initial guardian (NAP) and initial idealist personality type (DBD). Mathematical communication skills are analyzed based on the following criteria : (1) the ability to write down what is known and asked about the questions; (2) the ability to write answers according to the purpose of the questions; (3) the ability to write down reasons for answering questions; (4) the ability to make mathematical terms and symbols; (5) the ability to make images that are relevant to the questions; (6) the ability to make conclusions in their own language. The results showed that subjects with guardian personality type were only able to master the five criteria of mathematical communication ability. The subject was unable to conclude with his own language. The results showed that subjects with idealist personality type were only able to master the five criteria of mathematical communication ability but the subject does not master the third criterian, the subject is unable to write down the reasons for answering the question.

Abstract

The ability to understand students concepts is important. But the ability to understand the concept of students does not grow without just passing on an action from a serious educator in dealing with this problem. Developing learning objectives in general is one of the right steps taken by educators in learning. Bloom Revision Taxonomy that researchers will use in developing learning objectives in this study. so this study aims to describe students abilities in understanding concepts through Bloom Revisions taxonomy. This type of research uses a qualitative descriptive method to see students understanding of concepts in the implementation of microteaching in accordance with taxonomic steps of the revised bloom on the Education of Mathematics students at UIN Raden Intan in the sixth semester. Data collection techniques are tests on the implementation of microteaching and interviews. Based on the results of the assessment seen in the results of the observation sheet on the implementation of the learning that the steps of Blooms Taxonomy can be applied in accordance with the selected indicators and in general students have been able to understand mathematical concepts well. So it can be concluded that the application of Bloom Revised Taxonomy in learning can improve students ability to understand concepts

Abstract

Mathematics is a means of communication science about patterns that are useful to practice thinking logically, critically, creative and innovative.  The importance of mathematics in education is inversely related to the interest of students, because mathematics is considered to be difficult and tedious, it is necessary for the innovation in learning so that math seems easy and interesting, namely one of them with developing a learning media in the form of a video by using the app Sparkols video scribe. The purpose of this research is learning media math using software Sparkol Video scribe on the main discussion of linear program simplex method, as well as test the feasibility and know the response of students to the media. This study uses a model ADDIE which includes 5 steps, namely: analysis (analyze), planning (design), development (development), implementation (implementation), and evaluation (evaluation). The feasibility of learning media obtained from the results of the validation by media experts and matter experts with the category and the attractiveness of the video data obtained from a questionnaire filled by the students include small class and large class and qualitatively qualified interesting.

Abstract

This study aims to determine the effect of the use of the super-scaled model of scaffolding on students mathematical problem solving abilities. The sampling technique used was cluster random sampling with 3 classes namely experimental class 1 (the class was treated with scaffolding assisted superememe learning model), experimental class 2 (superitem learning only) and control class (the conventional treatment class). Hypothesis testing used is anava 1 cell path is not the same. The results of the study found that there were differences in students mathematical problem solving abilities by using learning models of scaffolding assisted supermarkets. Furthermore, the mathematical problem solving ability of students with the super-intensive learning model assisted by scaffholding is the same as the mathematical problem-solving ability of students using superemit learning models. The mathematical problem solving ability of students with superficial learning models assisted by scaffholding is better than the students mathematical problem-solving abilities using conventional learning models. Furthermore, the mathematical problem solving ability of students with superemit learning models is the same as the mathematical problem solving ability of students using conventional learning models.
