This study aims to describe the problem-solving ability of two-variable
linear equation system material in students with visual, auditorial, and kinesthetic
learning styles. This type of research is descriptive qualitative. The subjects of the
study were grade VIIIB students of SMPN 1 Gunungsari for the 2023/2024 school
year, totaling 20 students, with 5 students of visual learning style, 7 students of
auditorial learning style, and 8 students of kinesthetic learning style. The sampling
technique is carried out by purposive sampling technique. The research instruments
are questionnaires, test questions, and interviews. The data analysis technique used
is data reduction, data presentation, and conclusions. Analysis is carried out based
on John Dewey's stages, namely facing problems, defining problems, finding
solutions, testing several solutions, and choosing the best hypothesis. Based on the
results of the study, it was obtained that, students of visual learning style, in general,
have high problem-solving skills because they are able to carry out all five stages.
Students of auditorial learning style, in general, have high problem-solving skills,
where auditorial students are able to carry out all five stages. Meanwhile, the
kinesthetic learning style has moderate problem-solving abilities, where kinesthetic
students are only able to carry out four stages, because at the stage of choosing the
best hypothesis, kinesthetic students are not able to carry it out

The independent and communication skills in mathematics learning are
two very important competency components that students must master and greatly
influence student learning outcomes. However, students at SMPN 4 Mataram have
relatively low independence and mathematical communication skills. As a result,
student learning outcomes obtained by more than 50% are classically below the
KKM. Therefore, this research focuses on two variables that influence learning
outcomes, namely independence and mathematical communication skills. This
research uses quantitative methods. The population was 125 class VIII students.
Using Simple Random Sampling, a sample of 32 students was obtained. Data on
class VIII students at SMPN 4 Mataram for the 2023/2024 academic year was
collected using questionnaires and tests. By using regression analysis the results
obtained were 1) There was an influence of independence on student learning
outcomes in relation and function material of 25,4%; 2) There is an influence of
mathematical communication skills on learning outcomes V of 43,8%. 3) There is an
influence of independence and mathematical communication skills together on
student learning outcomes in relation and function material of 72,4%

The Effect of Mathematics Anxiety on the Problem-Solving Ability

Math anxiety is a disturbing condition in mathematics learning. The influence of math anxiety is one of the causes of low student problem-solving ability. This study aims to obtain the influence of mathematics anxiety on the problem-solving ability of grade XI science students of SMA Negeri 1 Gerung for the 2023/2024 school year. The type of research used in this study is quantitative research with ex-post facto research methods. The data analysis used is inferential statistical analysis. The results of the t-test that obtained a value of t_hitung = 6.955 > t_tabel = 1.967 with a sig value = 0.05 or 5% then there is a significant influence between mathematical anxiety on problem solving ability. The results of the regression equation Y ̂ = 4.072 – 0.831X, showed that there was a negative relationship between mathematical anxiety and problem-solving ability. The result of a correlation coefficient of 0.459 shows that between mathematical anxiety and problem-solving ability has a moderate relationship. The coefficient of determination points to 0.617 or 61.7%.

This research aimed to determine the effect of the Realistic
Mathematics Education (RME) learning model on students critical thinking
ability for systems of linear equations with two variabels material in class VIII at
SMP Negeri 3 Jerowaru for the academic year 2023/2024. Research with a
quantitative approach that uses a quasi-experimental design, the experimental
class learning using the RME learning model while the control class using direct
learning. The population in this study was 3 class VIII students. The samples
were taken using a simple random sampling technique, resulting in class VIII A
as the experimental class and VIII B as the control class. Data collection was
carried out using critical thinking ability test questions (posttest). From the
research results, it was found that there were differences between the
experimental class and the control class. Judging from the average score of the
experimental class 69.08 and the control class 58.40, this shows that the critical
thinking ability of the class whose learning uses RME is better than the class
whose learning uses direct learning. The effect size test results obtained were
0.69, which is in the medium category. So it can be concluded that there is an
effect of the RME learning model on students' critical thinking skills in SPLDV
material in class VIII of SMP Negeri 3 Jerowaru in the medium category.

Augmented Reality in the Application of 3 Dimensional Objects as Laboratory Equipment

Gilang Primajati — Sun, 31 Mar 2024 00:00:00 +0800

In today's developing era, quite a few schools still have limitations or lack
of learning media. So technology is needed to support the learning process so that
it is easier for students to learn both online and offline. This research aims to create
and add Augmented Reality-based learning media at SMA Negeri 1 Plampang. The
learning media created is a chemistry practical learning application using the
Android platform which will be implemented in the chemistry textbook for class X
MIPA students at SMA Negeri 1 Plampang. Augmented Reality technology makes
it possible to combine the virtual world and the real world in real time. So it will be
able to provide a real learning experience. By applying Augmented Reality to the
Chemistry textbook, students will be able to get to know the chemistry practical
tools displayed through the application without needing to look directly into the
chemistry laboratory.
The research method used is the ADDIE method which consists of analysis, design,
development, implementation and evaluation stages. This method will produce
output in the form of an Android-based application that uses Augmented Reality
technology to display 3D objects for chemistry practical tools. Based on the results
of the questionnaire or questionnaire that was given to respondents, the result was
that the application that had been created was feasible and could be used as a
learning medium that would be used at SMA Negeri 1 Plampang in the Chemistry
subject class X-IPA CHAPTER 1
