Abstract

Integral calculus is one of the mathematics courses that requires an adequate level of reasoning, communication skills and higher-order thinking skills to be able to understand and solve problems. The purpose of this study was to identify student errors based on Newman's Error Analysis (NEA) in solving integral calculus problems accompanied by the provision of scaffolding. The research subjects were students of STKIP Hermon Timika's Mathematics Education Study Program who attended integral calculus lectures. The results showed that there were no errors made by students on indicator type 1 (reading error), the average student made an error in indicator 2 (comprehension error) of 39%, the average error on indicator 3 (transformation error) was 71%. , the average error in indicator 4 (process skills error) is 76% and the average error most often made in indicator 5 (encoding error) is 87%. The scaffolding used to overcome all student errors only reached level 2 scaffolding, namely explaining, reviewing, and restructuring. The provision of scaffolding by lecturers is to explain, review and restructure so as to encourage students to correct these mistakes. Based on the results of this study, lecturers are expected to conduct meaningful lecture activities for students of STKIP Hermon Timika's Mathematics Education Study, so that it is not easy to forget the material concepts that have been explained.

Abstract

Survey of Overhead Passing Skills in Volleyball Athletes at YPPK Santo Bernardus Junior High School in Timika. Overhead passing is a fundamental technique in volleyball. The YPPK Santo Bernardus Junior High School volleyball extracurricular activities do not optimize overhead passing skills in volleyball. Therefore, the YPPK Santo Bernardus Junior High School volleyball extracurricular activities lack mastery of overhead passing skills. This research is needed to identify the overhead passing skills of YPPK Santo Bernardus Junior High School volleyball extracurricular athletes. This research aims to determine the extent of their overhead passing skills. This research was conducted to determine the overhead passing skills of YPPK Santo Bernardus Junior High School volleyball extracurricular athletes at Timika.This research is a quantitative descriptive study. The method used in this study was a survey with test and measurement data collection techniques. The population in this study were the volleyball extracurricular athletes of YPPK Santo Bernardus Junior High School in Timika, with a total of 20 people, who were then used as research samples. The instrument in this study was the AAHPER face pass volleyball test. The data analysis technique used descriptive analysis carried out in the form of a percentage of the passing ability of the volleyball extracurricular athletes of YPPK Santo Bernardus Junior High School. The results of the study from 20 volleyball extracurricular athletes of YPPK Santo Bernardus Junior High School in Timika obtained 2 athletes (10%) with a very poor category, 3 athletes (15%) with a poor category, 8 athletes (40%) with a sufficient category, 6 athletes (30%) with a good category, and 1 athlete (5%) with a very good category. The level of passing ability of the volleyball extracurricular athletes of YPPK Santo Bernardus Junior High School in Timika was categorized as sufficient. The results of this study provide useful input for the Volleyball Extracurricular of YPPK Santo Bernardus Timika Middle School and the Volleyball Extracurricular coaches of YPPK Santo Bernardus Timika Middle School to improve the passing ability of the Volleyball Extracurricular Athletes of YPPK Santo Bernardus Timika Middle School.
