Scientific Learning

Based on observations and interviews with a science teacher at a junior high school in Pesisir Selatan Regency, it is known that there are still many science teachers who have not carried out practicum activities in scientific learning. Science kits are rarely used by teachers in science learning. The main reason is that the competence of science teachers in operating the science kit is still low. To improve the competence of science teachers in using KIT, it is very necessary to carry out activities to optimize the use of KIT for science teachers. The purpose of this study was to improve the competence of science teachers in using IPA KIT as a support for scientific learning. This type of research is a quasi-experimental design with a pretest-posttest using multiple choice test instruments at the beginning and at the end of the study. From the results of this study, it is known that there is an increase in the competence of science teachers in using science kits, with the percentage increase of 29.25%.

Scientific Approach

In order to survive and improve self quality in higher levels of education and work, generic science skills are needed. Generic science skill is the skill that can be grown from science learning as a provision to pursue careers in a broader field. In this day and age, many things can be done by using devices, including physics learning. This study aims to find out the differences of generic science skills improvement between a class that apply solar system learning with a scientific approach assisted by Solar System Scope with a class that do not use Solar System Scope. The method used in this study was quasi-experiment with the control group pretest-posttest design. The sample consisted of 31 experimental class students and 31 control class students in the junior high school in Bandung. Both classes were given the multiple choice test. The results of data analysis showed an improvement in both classes with N-gain 45.9% in the experimental class and 22.8% in the control class. The conclusion of this study can be showed by Mann Whitney hypothesis test which produces z = -3.60. It shows that there is a significant differences of generic science skills improvement between both classes after the implementation of solar system learning assisted by Solar System Scope.

Learning English

Having many vocabularies  is very important in learning English. Vocabulary is one of factors that determines the success of four English Skills. The students who have enough vocabulary could be easier in learning English. From this reason, the teacher should give a good technique to teach vocabulary. Crossword technique is one of an interesting, enjoyable, and fun that should be used by the teacher. Crossword technique is also effective in enrich students’ vocabulary. By implementing the crossword technique the students don’t feel memorizing the vocabularies, they could add their vocabulary unconsciously. This study is aimed to find the effect of crossword technique on students’ vocabulary mastery. It was done at MTs Miftahul Ulum Palengaan Pamekasan. The participant  is the seventh grade students. The total number of the participant is 20 students. This study was quantitative research and quasi experimental as the design. Vocabulary test was used to collect the data which consist of 50 questions. The form of test was multiple choice test. There were two tests, namely pretest and posttest. Pretest was done before giving treatment and posttest was done after giving treatment. To achieve the objective of this study the data were analyzed by using dependent t test with the help of SPSS 20. The result turned out to test the hypothesis which states students score in the posttest are different from their score in the pretest. The finding showed that the alternative hypothesis is accepted. It was proven by the result of computation of t-value is higher than critical 0.05 with df 19.It means that the alternative hypothesis (Hi) was accepted.  From those explanations above, it could be concluded that there is significant effect of crossword technique on the first grade students’ vocabulary mastery at MTs Miftahul Ulum Gunung Tangis Palengaan Pamekasan. Therefore, teaching vocabulary by using crossword technique was more effective than teaching vocabulary conventionally.From this finding, the researcher suggests for the English teacher to use crossword technique in teaching vocabulary because this technique is very enjoyable and interesting for the students. Moreover, for the institution who doesn’t have enough facilities.

Android media is one of the learning media that is easy and interesting to use. This study aimed to develop an Android-based science learning media that fulfills valid, practical, and effective aspects. The research method used 3 stages of the 4D model, namely (1) define, (2) design, and (3) develop. The dissemination stage was not done because it took a long time. The research instruments were validation sheets, questionnaire, and test. The media validity test was carried out by material experts and media experts. Practicality tests were carried out by teachers and students. The effective tests were carried out by student. The data analysis techniques were qualitative and quantitative descriptive analysis. The effective test used a quasi-experimental method with an intact-group comparison design. The results showed that the android-based science learning media fulfilled valid criteria by material experts and media experts. The android-based science learning media fulfilled practical criteria by junior high school science teachers and students. There were differences in learning achievement for students who used Android-based science media and those who learned without using the media. The learning achievement for students who used Android-based science learning media was better than the students who learned without using android-based science learning media; this media can be the alternative of online learning.

Vocabulary is an important component in learning a language. Vocabulary is used to communicate to each other through listening, writing, speaking, and reading. These skills are closely related to vocabulary mastery. However, students have difficulties in understanding the vocabularies from their reading or listening activities. This research belongs to quantitative study using quasi experimental of nonequivalent control group design to find out the influence of using Hangman game on the seventh graders’ vocabulary mastery. The data were collected through a multiple-choice test. The hypothesis is tested using t-test. From the calculation of t-test, it was found that tobserved = 2.7, with df = 30+29-2 = 57 in ttable = 2.0, because tobserved ≥ ttable or 2.7 ≥ 2.0. Therefore, it can be concluded H0 is rejected, while Ha is accepted. In other words, “Hangman game influences the seventh graders’ vocabulary mastery.”
