Abstract

Assessments play an important role in chemistry learning and for specific uses. The construction of a test based on multiple representation approaches is needed for measuring the 21st century thinking skills. This study aims to construct and validate a standardized test to measure students’ analytical thinking and chemical representation ability in rate of reaction topic. The test captures four aspects on analytical thinking and four levels of multiple representations (macroscopic, sub-microscopic, symbolic and mathematic). A group of experts confirmed the construct and face validity of the Test of Analytical Thinking based on Multiple Representation (TAT-MR) with 32 items. The TAT-MR was then validated by participating 449 high school students. The test characteristics were analyzed usingRasch model with Partial Credit Model-1 Parameter Logistic (PCM-1PL) approach. The results of theRaschmodeling show that there are 22 TAT-MR items with excellent reliability. Hence, the TAT-MR is acceptable as a good instrument to collect the data. This study suggests that TAT-MR will prove to be a useful instrument for measuring the students’ ability on analytical thinking and chemical representation for rate of reaction topic in chemistry learning.

Abstract

A decision-making process in an organization is more effective if it is supported by reliable and valid information systems. Management Information System (MIS) and Decision Support System (DSS) are two systems commonly used by organizational leaders to collect information for making the Quality of Decision (QD). This study aimed to empirically investigate MIS influences on vocational high school principals’ QD. Besides, this study examined the moderation effect of the DSS on the decision-making processes. This quantitative research employed the survey method and purposive sampling technique. As many as 60 vocational high school principals and vice-principals in Yogyakarta, Indonesia were the participants of this study. They filled in questionnaires consisting of 19 items that were developed using the Likert scale. The quantitative data obtained were analyzed using Structural Equation Modeling. The research findings show that MIS has a significant effect on the quality of the decision-making process by vocational high school principals. However, for improving the decision quality, the model must be assisted by DSS as the moderator variable. MIS carries information required for principals while DSS provides data, model, and analysis instruments used for special cases in vocational high schools.
