The Effect of Using Guessing Game on Students Vocabulary Achievement at Grade VIII of MTSN 6 Agam

Vocabulary is a component of words with meaning and one of the most essential aspects of learning English. However, pupils are not taught vocabulary specifically in school. This results in a large number of students who lack fundamental vocabulary knowledge, despite the fact that vocabulary is one of the most essential components that students must comprehend in order to learn effectively in class. The purpose of this study was to determine whether the use of a guessing game has a significant impact on students' vocabulary achievement. This research employed a quantitative method and a quasi-experimental design; the research population was eighth-grade MTsN 6 Agam students. The sample was collected using a technique of purposive sampling. Students from the two classes, experimental class with 30 students and control class with 31 students, were given a pre- and post-test. This research instrument is a vocabulary test with 25 multiple-choice questions. The data were analyzed with SPSS 26. The calculated post-test result for the experimental class revealed a mean score of 89.47. It exceeds the mean score of the control group, which was 62.58. The standard deviation of each class is then calculated. Using Independent sample t-test, the researcher compared post-test experimental class and control class using the t-test formula. The output indicates that the value of Sig. (2-tailed) is 0.00 0.05. It indicates that Ha is acceptable. There is a substantial difference between students who are taught using Guessing game and those who are not. The result is also indicated by the fact that the mean post-test score of the experimental group (89.47) is higher than that of the control group (62.28). It indicates that students who are taught with Guessing game are superior to those who are not. Guessing game has a significant impact on the vocabulary attainment of eighth-grade MTsN 6 Agam students.

Development of Teaching Factory Model to Enhance Creativity of Students in the Home Economics Department of the Faculty of Engineering, UNM, Indonesia

The research aims to (1) develop an appropriate 6M teaching factory model for practical learning in the Department of Family Welfare Education, Faculty of Engineering, Universitas Negeri Makassar with a concentration in Cosmetology, (2) produce a 6M teaching factory model that is valid, practical, and effective for practical learning in the Department of Family Welfare Education, Faculty of Engineering, Universitas Negeri Makassar with a concentration in Cosmetology. This study is an R & D (Research and Development)-based development research. The subjects used were 20 students from the Cosmetology concentration. The development method adapted in this study is derived from the Borg and Gall Model, which includes three main stages, namely: preliminary study covering field surveys, document analysis, and theoretical considerations; the design phase involving the creation of a teaching factory model draft and the improvement of the model; and the experimental phase that includes initial inspection, large-scale testing, and final refinement of the product. The results of this research are the creation of a teaching factory learning model called the TEFA 6M, along with operational tools including the TEFA 6M model book, Syllabus, modules, jobsheet, and LPPO. This model is designed to strengthen the practical abilities of students. The TEFA 6M model is divided into seven phases in one round, starting from pre-order, pre-production, production, post-production, packaging, to order delivery. One TEFA 6M model cycle combines soft skill and hard skill activities. The implementation of this model uses a block and rotating system and is concluded with a competency assessment. The developed TEFA 6M model has been validated by experts, revised, and tested on both small and large scales. Based on the t-test results, it is known that the Sig. (2-tailed) value of 0.000 is smaller than the probability of 0.05, so it can be concluded that there is a difference in test results between the experimental class posttest and the control class posttest. Furthermore, for the average score of the experimental group, a score of 78.38 was obtained, and 42.36 in the control group; thus, the 6M Teaching Factory Learning Model can be said to be effective in the experimental class in improving student competencies in the Facial Makeup Techniques course. The research indicates that the TEFA-6M model has met the standard of validity. Based on the evaluations carried out, it is known that this teaching approach is practical, in terms of management abilities by the lecturer, and effective, as seen from the level of student activity, student reactions to the functionality and implementation of the model, and from test results that assess task completion.

The Influence of Implementing Problem-Based E-Modules on Students' Motivation And Learning Outcomes on Colloid Systems Chemistry Materials in Senior High School

The research aims to determine the effect of implementing problem-based e-Modules on student motivation and learning outcomes in colloid system material in class XI SMA Negeri 9 Medan.

Meanwhile, from T-test analysis found that the value of sig (2-tailed) was 0.000. As the result, it can be seen that 0.00 < 0.05 which mean that null hypothesis (Ho) was rejected ad the alternative hypothesis (Ha) was accepted. It means that there is significant effect of using Listen-Read-Discuss (LRD) strategy toward students reading comprehension at tenth grade students of SMAN 11 Jambi.

The The Influence of Mind Mapping Model towardsthe Result on Economical Lesson for Tenth Grade Islamic Senior High School in MAN 2 Kutai Kartanegara

The study examines the use of mind mapping model and its result in Economical lesson for tenth grade Islamic Senior High School in MAN 2 Kutai Kartanegara that involves two classes consisting of 35 male and 43 female students. This study uses experimental research by using post-test only control group design as the method. The data collection technique is used by using documentation, interview with the teacher who teaches Economical lesson, test, and questionnaire of the students’ respond. The technique of analyzing the data by using t-test to examine the hypothesis. The results of the study show that the implementation of using mind mapping as a leaning model is running well. The student from experimental class, X-IPS 1 or social studies class 1shows the significant changes and conventional class, X-IPS 2 social studies class 2 shows not really the significant changes. But, from these two classes together show development from how they study, their interests in learning Economical lesson, they become active, creative, and critical student especially their result in score to pass the standard lesson value in Economic is 75 in their school. Based on the research, the average score of the first post-test shows 98,5 in experimental class and 87,64 in conventional class. In the second post-test, the averagescore in experimental class having more significant difference until 10,86. Then, the average score for both two post-test in experimental class is 86,91 and conventional class is 82,07. From ten questions of questionnaire are reached each questions get 70% for the statement of agreement in using mind mapping as learning model to understand and learn Economical lesson. The analyzed of the data by using t-test shows tcount equals 5,931 and ttable equals 5%, and the percent of the freedom (dk) equals 76 or 1,991. Because tcount is bigger than ttable, means the use of mind mapping to increase the result of the students’ learning for economical lesson is accepted and revealed. The use of using mind mapping is also expected to solve the lower student speed in learning a certain lesson, the student to learn other lessons to increase their understanding, and the student and teacher are able to have good interaction and bounding to prepare them in facing the real word especially that links with Economy.
