This research is a quasi-experimental study that aims to determine the effect of interactive video-assisted Blended Learning models on mathematical problem solving abilities. This research was conducted at SMPN 13 Serang City class VIII. The population in this study consisted of 10 classes VIII and taken 2 classes to be sampled. Sampling was done by cluster random sampling technique. The Blended Learning model used in this study isconventional learning in class by involving online resources and online activities which are not a requirement for students to follow. While the video used is a video adopted from one of the paid online learning rooms, Ruang Guru. Problem solving ability is measured using a test in the form of a valid and reliable question description. Furthermore, the data obtained were analyzed using quantitative descriptive analysis.

Face To Face Learning

This research is based on the background of the low mathematical problem solving abilities due to less effective learning, especially lack of lesson hours. Blended learning is a two-way learning model namely face-to-face learning and online learning, while E-learning is a face-to-face learning model. The blended learning and e-learning learning model requires online media such as Edmodo. Efforts to address these problems, researchers aim to determine the effect of these two learning on improving mathematical problem solving abilities. The research method used in this study uses quasi-experimental methods (Quasy experimental design) with the type of research used is the pretest-posttest control group design. The data collection technique uses a randomized class technique, where the population is all eighth grade students of SMP N 21 Bandar Lampung. The hypothesis test used is gain-test with analysis techniques using one way ANOVA. From the results of the study, blended learning and e-learning using edmodo there was an increase in mathematical problem solving skills with moderate levels of calcification.

The Impact

Creating an enjoyable atmosphere and fostering creativity are the two most required components in learning mathematics. Hence, creativity would enable students to formulate something new. In addition, creativity is one of the most important and highest competencies in Bloom’s latest taxonomy. Furthermore, it is necessary to be possessed by everyone including prospective teachers. Not only for producing products in the form of objects, but the term creative also refers to problem solving in mathematic problems. This research is conducted to obtain a detail description regarding the impact of 3CM learning model among blended learning toward the enhancement of students’ creative thinking skills in mathematical problem solving. To achieve this goal, a pre-experimental design with one group pre-test post-test design pattern is chosen. Creative thinking skills are measured by test techniques and are emulated with observation techniques. Observations were performed when students worked on the test. The impact of 3CM learning with blended learning seen from test results paired sample T tests with the help of SPSS program a that are acquired from close ended questionnaire techniques. The results show that the average of pre-test is 60.51 and the average of post-test is 75.96. As for the results of paired T tests is the test got sig value (2-tailed) 0.000, and hence there was a significant gap among the results of pre-test and post-test. All of these results imply that 3CM learning within blended learning is undoubtedly able to increase students’ creativity in solving mathematical problems. This is due to the learning situation and activities which push students to do systematic thinking. It was started by criticizing the enchanting contextual problems, creating creative products based on particular mathematical concepts, and ended by having meaningful reflection.

The Ideal

The reconstruction of a three-dimensional image of a specimen from a set of electron micrographs reduces, under certain assumptions about the imaging process in the microscope, to the mathematical problem of reconstructing a density distribution from a set of its plane projections.In the absence of noise we can formulate a purely geometrical criterion, which, for a general object, fixes the resolution attainable from a given finite number of views in terms of the size of the object. For simplicity we take the ideal case of projections collected by a series of m equally spaced tilts about a single axis.
