Abstract

The study tries to see the effect of different sample sizes on the reliability of creativity tests using Cronbach’s alpha. In addition, the background of the sample (gender and grade) is also detected. The study has a practical significance for designing a sample for estimating reliability using Cronbach alpha. The secondary data are used for analysis. The sample of creativity test is determined purposively, that is, has been administered to 1,960 students. The α-coefficient calculation uses the SPSS program. The result proves in the total sample, the creativity test is reliable (α=0.852). In small sample sizes, the α-coefficients values vary greatly in the different test groups. In the larger sample size, the α-coefficients are closer to constant in the different test groups. For a polytomous scale test with a length of 20 items, the α-coefficients obtained close to constant on the sample size of more than 80 testees. This result indicates for the optimum result the sample size is at least four times larger than the number of test items in reliability analysis, especially Cronbach alpha. Based on the gender aspect, descriptively the α-coefficient in the male group (0.846) was almost equal to the female group (0.851). By grouping the testees based on the grades, there are slight differences in α-coefficients in class IV (0.850), class V (0.841), and class VI (0.809). Regarding the results of this study, in the reliability estimation of test development, it is suggested to consider the adequacy and the characteristic of samples.

Abstract

A misconception is one of the learning obstacles that often occurs in biology class. This study aims to construct a diagnostic instrument to detect misconceptions of biological concepts during the first semester of senior high school and test the quality of the developed instrument. The instrument development model used was a modification of the Oriondo, Dallo-Antonio, and Azwar models. The construction begins with planning the measuring domain and preparing the blueprint for the test instrument. The processes were followed by an instrument seminar, peer review, expert judgment validation, and trying out the test on 885 students. In addition, an unstructured interview with the teachers determines the feasibility of the test instrument. The test content validity according to the Aiken formula is 0.85; the items have different levels of difficulty and good discriminating power; the number of 62 items fits the partial credit model. The reliability of the test is shown by a Kappa coefficient of 0.47. Thus, the test instrument proved to be valid and reliable. Thirteen teachers from eleven schools stated that the test is worthy of use in learning. For the school level, the instrument meets the criteria of a good test instrument.

Abstract

In this study, the researchers want to find out how much better students learn mechanical measuring instruments when they use the NHT type of joint learning model compared to when they use the traditional model of learning at SMKN 1 Tunjung Teja. A non-equivalent control group approach is used in this kind of study, which is kind of like an experiment. The people who took part in this study were students in class X at TKRO SMKN 1 Tunjung Teja. A learning outcome test was used as a study tool, and the T-test and N-gain test were used to analyze the results. The results showed that the experimental class that used the NHT learning method learned a lot. They got an average score of 22.80 on the pretest and 90.80 on the posttest. The control class had an average score of 21.47 on the pre-test and 49.26 on the post-test for learning results. A significant value of 0.00 ? 0.05 was found when the independent sample t-test test was used to test the claim. The N-gain number for the experimental class was 88.10% with high criteria, while it was 35.71% for the control class with intermediate criteria. This shows that the students learned more. What this means is that using the NHT type group learning model makes learning about mechanical measuring tools much more effective.

Abstract

This study aims to determine the level of critical and creative thinking skills of students of Mechanical Engineering Vocational Schools. This study uses a quantitative approach with a survey method and data analysis techniques with descriptive analysis, data collection techniques by distributing essay test sheets to all students of mechanical engineering expertise programs. The results of the study show that: (1). The average level of students' critical thinking skills is low. The low level of critical thinking skills possessed by students is due to the learning process which is less effective in developing the interests, talents and potentials that exist in each student. (2). The average level of students' creative thinking skills is low because many of the answers from students are mostly the same.
