This study aims to determine the item response theory model which is more accurate in estimating students' mathematical abilities. The models compared in this study are Multiple Choice Model and Three-Parameter Logistic Model. Data used in this study are the responses of a mathematical test of 1704 eighth-grade junior high school students from six schools in the Depok City, West Java. The Sampling is done by using a purposive random sampling technique. The mathematics test used for research data collection consisted of 30 multiple choice format items. After the data is obtained, Research hypotheses were tested using the variance test method (F-test) to find out which model is more accurate in estimating ability parameters. The results showed that Fvalue is obtained 1.089, and  Ftable is 1.087, the value of Fvalue > Ftable, so it concluded that Ho rejected. That means Multiple Choice Model is more accurate than Three-Parameter Logistic Model in estimating the parameters of students' mathematical abilities. This makes the Multiple-Choice Model a recommended model for estimating mathematical ability in MC item format tests, especially in the field of mathematics and other fields that have similar characteristics.
本研究旨在确定更准确评估学生数学能力的项目反应理论模型。本研究比较的模型是选择模型和三参数Logistic模型。本研究使用的数据是西爪哇德波市六所学校1704名初八年级学生的数学测试结果。抽样是通过使用有目的的随机抽样技术完成的。用于研究数据收集的数学测试由30个选择题组成。在获得数据后,使用方差检验方法(f检验)对研究假设进行检验,以找出哪种模型在估计能力参数方面更准确。结果表明,得到的Fvalue为1.089,and Ftable为1.087,Fvalue的值> Ftable,因此得出Ho拒绝的结论。这意味着选择题模型比三参数Logistic模型更准确地估计学生数学能力的参数。这使得选择题模型成为MC项目格式测试中评估数学能力的推荐模型,特别是在数学领域和其他具有类似特征的领域。

The study aimed at improving students’ learning outcomes about football through the inquiry learning model at Vocational High School 2 Makassar. Data were collected using PJOK learning result test and observation. The results of recapitulation between cycles after implementing inquiry learning model indicate that football learning outcomes of students in grade X TKJ 1 at Vocational High School 2 Makassar improved, proven by the result in cycle I that 6 (17.1%) out of 35 students were in Moderate scale and only 1 student (2.9%) was in Poor scale. In cycle II, the learning outcomes improve as there were 10 students (28.6%) in Moderate scale. Classically, cycle I is stated as unsuccessful because only 74.29% of students were in the complete category and has not achieved successful indicators which had been determined. In cycle II, there was an improvement of completeness which was stated as successful because 91.43% of students were in the complete category and has not achieved successful indicator which had been determined, which was 80%. The inquiry learning model applied in teaching football can improve learning outcomes based on the achievement of learning results completeness classically and individually.
本研究旨在通过探究性学习模式,提高望加锡职业中学2期学生对足球的学习效果。采用PJOK学习成绩测试和观察收集数据。实施探究学习模式后的周期间重述结果表明,望加锡职业高中2年级X年级tkj1年级学生的足球学习成绩有所提高,周期1的结果证明35名学生中有6名(17.1%)处于中等水平,只有1名(2.9%)处于较差水平。在第二阶段,有10名学生(28.6%)达到中等水平。经典地说,周期I是不成功的,因为只有74.29%的学生在完整的类别中,没有达到已经确定的成功指标。在周期II中,由于91.43%的学生处于完整类别中,并且尚未达到已确定的成功指标,即80%,因此完整性有所提高,被称为成功。在足球教学中应用研究性学习模式,可以在经典学习成果完备性和个体学习成果完备性的基础上提高学习效果。

Skills and competencies are highly regarded in todays global market. Different agencies specifically those seeking for  technologists, technicians, and engineers, have stressed out that skills and competencies as major components  for individual workers.  This aimed to determine  the relevance and appropriateness of acquired skills and competencies by industrial technology graduates, and determine the extent of use of skills and competencies in the current employment. Review of related literatures and studies have been considered in the realization, understanding, analysis, and interpretation of this research exploration. A descriptive method of research was used with 78 graduates from 2015-2016 and 117 graduates from 2016-2017, who participated in the study survey process. The BatStateU Standardized Questionnaire was used to gather data. A brief interview and talk during the visit of alumni in the university was also considered, as well as the other means of social media like email, facebook, messenger, and text messaging.   Results show that skills and competecnices acquired by industrial technology graduates are all relevant and appropriate.  The study also found that there is some to great extent use of acquired skills and competencies to their current employment. The study implies that the acquired skills and competencies from the university significantly provided the graduates the opportunities ins the national and global markets and industries.
