Rockfall modeling programs are continually being upgraded with more sophisticated analysis tools, such as the use of the rigid body versus lump mass models. Engineers at mine sites utilizing the software may have varied experience related to these models, their associated input parameters, and how to interpret the generated results. To address this concern, researchers at the Spokane Mining Research Division (SMRD) of the U.S. National Institute for Occupational Safety and Health (NIOSH) investigated the influence of slope height, slope angle, slope material, and rock size for both rigid body and lump mass models in a 2-D statistical analysis program. Based on a literature search and industry input, specific ranges common to that of an open pit mining environment were chosen for each of the input parameters to determine 90% rock runout distance as well as their sensitivity to change. Data collected from this numerical analysis and simulation will be compared to empirical rockfall data gathered through the duration of the Highwall Safety project conducted by NIOSH from 2022-2026.</p>","PeriodicalId":30733,"journal":{"name":"Unnes Journal of Mathematics Education","volume":"6 1","pages":"1101-1112"},"PeriodicalIF":1.5,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11261587/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80414949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thereupon, the objectives of this study were: (1) to find out the differences of students' mathematics learning motivation before and after the use of differentiated instruction-based module, (2) to determine the effect of using differentiated instruction-based learning module on students’ mathematics learning motivation. This study used a quantitative approach and mathematics learning motivation questionnaire as the technique of collecting data. Also, to analyze the data this study used the T-Test (paired Samples T-Test) with the prerequisite of analysis, namely the normality and homogeneity test. Eventually, the results of analysis prerequisite analysis showed that both data were normally distributed and homogeneous.
