The occurrence of El Nino can be estimated by observing the sea surface temperature in Nino 3.4 region. Therefore, an accurate model on sea surface temperature prediction in Nino 3.4 region is needed to optimize the estimation of the occurrence of El Nino, such as ECMWF. However, the prediction model released by ECMWF still consists of some systematic errors or biases. This research aims to correct these biases using statistical bias correction techniques and evaluate the prediction model before and after correction. The statistical bias correction uses linear scaling, variance scaling, and distribution mapping techniques. The results show that statistical bias correction can reduce the prediction model bias. Also, the distribution mapping and variance scaling are more accurate than the linear scaling technique. Distribution mapping has better RMSE in December-March, and variance scaling has better RMSE in April-June also in October and November. However, in July-September, prediction from ECMWF has better RMSE. The application of statistical bias correction techniques has the highest refinement in January-March at the first lead time and in April at the fifth until the seventh lead time.

Teachers who hold a more potential digital literacy in education teach mathematics with patterns and procedures, leading to practical teaching mathematics. Influential digital literacy and higher thinking are not possible when teachers do not use technology to understand the concept of mathematics. Therefore, teachers are required to improve their technical abilities and higher thinking in mathematics learning. This research used a cross-sectional quantitative research. This research uses statistical analysis of the Kaiser Meyer-Oikin Test (KMO) and the Barlett's Test to obtain exploratory factor analysis. Subsequently, the analyzed using confirmatory factor analysis and structural equation model with Analysis of Moment Structure (AMOS). The purpose of this research is to provide an overview of the relationship between higher thinking skills and digital literacy. The review discoveries show that teachers' digital literacy has a more significant impact on the use of technology in the classroom, and teachers' higher thinking in the role of technology will encourage teachers to use more technology in their practical teaching. Teachers need to broaden their perspectives on the ability and quality of mathematics teaching that is more easily changed by changing practical instruction in the classroom. One of the reasons mathematics teachers still apply traditional teachings is the lower thinking and low level of digital literacy.

The presentation of teaching materials presented in the online platforms used has not been able to identify the extent of student understanding in problem-solving exploration. Therefore, this research aims to produce Kaizala teaching materials based on problem-solving exploration. The ADDIE (Analysis, Design, Development, Implementation, Evaluation) development model was used in this research to produce these teaching materials. The subjects of this research trial were grade VIII junior high school students in a public school in Ogan Komering Ulu Regency, Palembang. The choice of the place for this research was based on the fact that the mathematics learning carried out at the school was by utilizing social media platforms. The instruments used in this research consisted of validation sheets of material, language, presentation, and problem-solving integration, a questionnaire on the practicality of teaching materials, and a problem-solving ability test to assess the effectiveness of the developed teaching materials. The results showed that: (1) the developed teaching materials were in the valid criteria; (2) the practicality of the developed teaching materials are at very high and high criteria; (3) The developed teaching materials also meet the criteria of effectiveness, whereas many as 82 percent of the test subjects obtained a score of not less than 75 and the effect size value belongs to the large category.

The purpose of this research is to improve students’ mathematical logical intelligence through the online-based integration of local wisdom of Sulapa Eppa Walasuji. Sulapa Eppa Walasuji is one of the Bugis-Makassar local wisdoms with a unique pattern, appropriate to be used as a medium for learning transformation of geometry. Through the integration of local wisdom, Sulapa Eppa Walasuji can create contextual mathematics learning, so that students can easily understand the material by connecting real-life concepts. This research includes experimental research with a quasi-experimental design of the nonequivalent control group design type. The research instrument used was a mathematical logical intelligence test consisting of five essay questions. The data analysis used is descriptive statistics with gain score and effect size testing. The results showed that the mathematical logical intelligence of experimental class students increased by 43.16 with the effective contribution of the r effect size being 0.910. This indicates that the online-based integration of Sulapa Eppa Walasuji can improve students’ mathematical logical intelligence.

The independent variable is student learning interest, and the dependent variable is mathematical learning achievement.

Thirty research publications that satisfied the required criteria were utilized as the sample. Data analysis uses a quantitative meta-analysis approach with a correlation meta-analysis.

Then we verified the data using triangulation of constant comparative method from a test and a task-based interview with the stimulated recall. The results indicated two groups of students in proving strategy. Group I performed “appropriate” syntactic strategy and Group II vice versa. Blindness was experienced by the subject that does not recognize errors detection or the ambiguity of the proof. Mirage occurred when the subject recognizes an error detection on the proper strategy or application of a theorem, then is unable to verify the truth of his work. Misdirection appeared when the subject recognizes a lack of progress, then uses an incomplete or irrelevant concept. Vandalism emerged with no progress or detection of errors of the strategy then the subject performs some irrelevant steps to the issue or uses a misconception. Practically, the teachers can use these results for learning innovations in scaffolding-based proof courses. The scaffolding might need some development and application in supporting students to overcome difficulty in proving mathematical sentences.
