Abstract

[Title: Gender Typical in Communicating Middle School Mathematical Problem Solving]. The emphasis of mathematics learning, especially students' communication skills, needs to be considered from gender equality in solving mathematical problems. This study aims to describe: 1) the potential Mathematical Communication Skills (MCS) of students based on gender; 2) gender equality in communicating mathematical problem solving, and 3) the suitability of the form of the model or the applied form to develop students' MCS based on gender at school. This research is descriptive qualitative research conducted on all junior high school students in Langsa with a purposive sampling technique of 283 students. The data were collected through MCS and questionnaire tests which were analyzed descriptively using the concept of Miles and Huberman. The results showed that: 1) MCS of female students were better than male students in solving mathematical problems; 2) MCS of male students are better in suburban schools and female students are better in downtown schools, and 3) learning implementation plans are still limited in emphasizing MCS and learning tends to be cooperative and individual. It is recommended that learning plans refer to developing MCS that pay attention to students' gender equality in order to optimize mathematical problem-solving.

Abstract

[Title: Moving Average Filter for Time Lapse Gravity Anomaly Separation]. Interpretation of time-lapse gravity anomaly due to fluid injection in the reservoir is difficult when it mixed with shallow source anomalies. To solve the kind of problem, anomaly separation is performed with the method of Moving Average Filter. This study was conducted to obtain an effective method to separate the gravity anomaly of shallow sources on time-lapse gravity anomaly. Trials are conducted on anomaly models derived from reservoirs with three distinct depths that are 300, 600 and 900 meters. This forward model is then mixed with gravitational anomaly from the shallow source obtained from the field data. The mixed anomaly is then separated by a Moving Average filter. Results show that Moving Average filters can separate the shallow effect from the deep source anomaly and are effective up to a depth of 900 meters. The research is also beneficial for classroom learning in the computer programming class based on Matlab.

Abstract

[Title: The Effect of Open-Ended Problems on Mathematics Problem toward Students' Ability in Solving Linear Program Problems]. The purpose of this study is to determine whether the provision of linear program mathematical problems in the form of open-ended problems can affect students' problem-solving abilities. This research is an experiment with one sample group, 28 students of class XI IPA-2 in SMA Negeri 7 Mataram. Data was collected through tests and interviews that were statistically analyzed both descriptive and inferential. The validity of mathematical problems is based on expert judgment while the reliability is tested using product-moment correlation. Pre-test and post-test data have been tested both homogeneous and normally distributed. The homogeneity test uses the F-test statistics and the normality test uses the interpretation of skewness and kurtosis. The influence test is performed using one-party t-test statistics. Student problem-solving performance was assessed using a holistic rubric. All data is processed using data analysis tools on Microsoft Excel. This experiment showed success by obtaining an average test score of students when the pre-test was 39.58 which then increased when the post-test became 79.76. This increase was statistically significant as evidenced by the one-party t-test where tcount = 37.33> ttable = 1.67 at α = 0.05, which means that Ha was accepted. So it can be concluded that there is an effect of the treatment given a mathematical problem in the form of open-ended problems to the ability of students to solve linear program problems.

Abstract

Higher-Order Thinking Skills (HOTS) must be owned by students, and need to be assessed authentically. This study aimed to 1) analyze the efforts of high school teachers in Malang in developing a HOTS-authentic assessment in tissue structure materials; and 2) analyze the pre-validation final draft of the HOTS-authentic assessment model on tissue structure materials. The research method used was Research and Development (R&D). However, in line with the objectives, this publication only focuses on define, design, and develop. The developed part is only on the product (a pre-validation final draft). The research was carried out in state high schools in Malang (SSHS 1, 3, 4, 7, and 8). The study was conducted in April-November 2018. The subjects were 2 teachers from each school (10 teachers in total). Research data and findings were analyzed by descriptive-analytic qualitative. The results showed that teachers have included or considered HOTS aspects in lesson plans. However, the development of HOTS aspects and their assessment were not able to be carried out maximally. In practice, in a greater percentage, teachers use lesson plans without modification or making adjustments to student conditions. They modify and incorporate the HOTS aspect if there is an opportunity to discuss with other part who guide them. Therefore, the existence of this assessment model is very needed. The pre-validation final draft is essentially in the form of concepts that can be linked to the MGMP activities, and various related part, in an interactive and cyclical relationship (as a model for professional development of biology teachers).
