Analysis of junior high school students' questions based on bloom's revised taxonomy in terms of gender and school achievement level

Syahwa Adila Gepsi — 2024-06-30

Active involvement of students in the learning process is needed to make it easier for students to understand science material and to increase student curiosity. One of the important abilities to be developed is the skill of asking questions by students. In this study, researchers analysed the quantity and quality of students' questions in terms of gender differences and school achievement levels. This study aims to determine the profile of student questions in terms of gender and school achievement level and to find out whether there is a relationship between the level of student questions with gender and the level of student questions with school achievement level. The population of this study was 3 junior high schools / MTs in Ngemplak District, Boyolali Regency. The sampling technique used was cluster random sampling. The data collection technique used observation technique. The data analysis technique was descriptive and correlation test. The results of descriptive data analysis showed that there were differences in the profile of questions asked by students of different genders and students from schools with different levels of achievement, both in terms of the number, level and indicators of questions. As seen from the correlation test results, a significance value of 0.470 was obtained; meaning that there is no significant relationship between the level of questions and gender. The results of the correlation test between the level of questions and the level of school achievement also showed that there was no significant relationship between the level of questions and the level of school achievement, with a significance value of 0.531. These results may occur due to several other factors outside of gender and school achievement level, including the school zoning system and different learning time factors that make the difference in the level of questions based on gender and school achievement level insignificant.

This study aims to (1) analyze the effectiveness of the STEAM-based PjBL model on students' creative thinking skills and cognitive load on light and optical devices (2) analyze the effect of self-efficacy on students' creative thinking skills and cognitive load on light and optical devices (3) investigate the interaction of STEAM-based PJBL models and self-efficacy on students' creative thinking skills and cognitive load on light and optical devices. This research is quasi-experimental research with a pretest-posttest control group design. The population of this study was VIII grade students at one public junior high school in Blora Regency for the 2022/2023 academic year, totaling 252 students. The sample was determined using the cluster random sampling technique; the experimental class consisted of 32 students using the PjBL STEAM learning model, and the control class consisted of 31 students using the Discovery learning model. Data collection was carried out using test techniques in the form of creative thinking skills essay questions and non-tests in the form of cognitive load and self-efficacy questionnaires. The validity test technique used is content validity. The data analysis used was the MANOVA test. In the hypothesis test, it was found that H_0A was rejected (sig. 0.002 <0.05), H_0B was rejected (sig. 0.001 <0.05), and H_0AB was accepted (sig. 0.139 > 0.05). The conclusions obtained are (1) the learning model has an effect on creative thinking skills with the STEAM PjBL model, which has a better effect than discovery learning, (2) the learning model has an effect on students' cognitive load scores with the STEAM-PjBL model which can minimize cognitive load values which is better than the discovery learning model, (3) self-efficacy does not affect creative thinking skills but affects students' cognitive load, (4) and there is no interaction between learning models and self-efficacy on students' creative thinking skills and cognitive load. The research results can be used as study material and references for similar research on the effectiveness of STEAM-based PjBL learning models to improve students' creative thinking skills and minimize cognitive load scores in terms of self-efficacy levels for different materials.

The current implementation of IPAS (Integrated Science) learning in elementary schools lacks active student invoIvement in the Iearning proces, resulting in passive students and impacting their learning outcomes. This study aims to examine the effect of using the Inside Outside Circle (IOC) model, coupled with audiovisual media, on the learning outcomes of IPAS students. This research adopts a Quasi-ExperimentaI Design with a quantitativ aproach. The popuIation consists of all fourth-grade students, totaling 89 students. Sampling technique employed test of homogeneity, resulting in two homogenous classes: Class IV C (control group) and IV D (experimental group). Data from pre-tests and post-tests were analyzed using the t-test. The t-test results yielded a significance value (Sig. 2 taiIed) of (0.000) < 0.05, indicated a significant difference in the average student Iearning outcome for the experimental cIass, with an average pre-test score of (67.27) and an average post-test score of (83.64). Thus, it can be concIuded that the lnside Outside CircIe (lOC) Iearning model with audiovisual media has a significant impact on the IPAS learning outcomes of fourth grade student at Taman Siswa EIementary School, Turen, in the academic year 2023/2024.
