Go-Chemist! App and Its Impact on Students’ Attitudes Toward Chemistry

The current study aims to explore the impact of using the Go-Chemist! app on students’ attitudes toward chemistry on colligative properties. This pretest-posttest quasi-experimental design study involved 71 twelfth-grade students in Jakarta, Indonesia. One class was randomly assigned to a treatment group which was taught using a mobile application and another class was assigned to a comparison group which was taught using e-books. The Attitude Toward Chemistry Lessons Scale (ATCLS) was administered before and after instruction to both groups. To analyze the data, we employed independent and paired sample t-tests. The results indicated that after the intervention, the gap in attitude scores between the two groups was statistically significant in favor of the intervention group. Students in the treatment group also showed a statistically significant improvement in average scores from pre- to post-administration with a large effect size. This reflected the use of the Go-Chemist! app effectively increases students’ positive attitudes toward chemistry lessons on the topic of colligative properties.

The formation of subject-specific values as a two-step process: Self-concepts mediate the relation between achievement and values

Within the framework of a generalized internal/external frame of reference model, influences of social and dimensional comparisons of academic achievement on the formation of subject-specific values (or related constructs) are empirically well documented for secondary school students. Furthermore, a wide range of theories also hypothesize an effect of subject-specific self-concepts on values. Accordingly, prior studies suggested a mediating effect of self-concepts on the achievement–value relationship. However, these studies have been limited to two school subjects or exclusively math and science subjects. Based on data from N = 1,339 ninth- through twelfth-grade students, we extended prior research by relating students’ grades in mathematics, physics, social studies, German, English, and the second foreign language to value scores in these subjects; subject-specific self-concepts were included as mediators. Our results support the hypothesis of a full mediation of the relationship between grades and values through self-concepts. Additional analyses showed a comparable fit between a mediation model with direct paths from grades to values and a mediation model without these direct paths. We discuss which subject-specific self-concepts are the most important mediators for the achievement–value relationship and the importance of self-concepts for forming values above grades.

It could be seen that tcaunt was greater than ttable (17,39 1,68). The hypothesis was accepted. In the other words, there was a significant influence between using experiment method on physics achievement in mechanics waves subject at the twelfth grade students of SMA Negeri 1 Pangaribuan.

The Effect of Realistic Mathematics Education Approach and Learning Motivation To Improving Higher Order Thinking Skills By Controlling Students Intelligence Quotient

This study aimed to determine whether students' HOTS could be improved by using the Realistic Mathematics Education (RME) approach. More specifically, this research wants to know the effect of the RME approach on HOTS, it will be studied from students' learning motivation and will be controlled for students' Intelligence Quotient (IQ). The research design used was pretest-posttest control group design with covariables and the implementation of the research design was factorial design by level (2 X 3). The research samples were 110 twelfth grade students from two schools in East Jakarta in the 2022/2023 academic year. The results of the study showed that the increase in HOTS of students who were taught using the RME approach was higher than students who were taught with conventional learning after controlling for students' IQ. There are differences in HOTS abilities between students with high, medium, and low motivation after controlling for student IQ. There is an influence between the learning approach and learning motivation on HOTS abilities after controlling for students' Intelligence Quotient.

Gender Stratification and Changing in Gender Expectations: A comparative analysis between coeducational schools and single-sex schools in Erbil

This study explores the impact of coeducational schools on reducing gender inequality by comparing students' perspectives in coeducational and single-sex schools with similar academic levels. Seventh-grade (aged 12,13) and twelfth-grade (aged 17,18) students from three basic and three preparatory schools participate. Qualitative data is gathered through eight focused group interviews with 80 students and analyzed using coding. Quantitative data is collected through questionnaires, including students' perspectives on gender issues and controllable variables related to their home background. SPSS program is used for analysis, employing cross-tabulation and correlation. The study supports the "enlightenment approach" as both types of schools show changes in gender expectations, with twelfth-grade students exhibiting more egalitarian views. Gender inequality in teacher treatment was observed in all selected schools. Preparatory coeducational schools showed better treatment towards girls, while twelfth-grade girls faced inequality in a preparatory single-sex school for girls. Similarly, a significant gender inequality was found in teacher treatment towards boy students in the preparatory school for boys. This indicates that the school somewhat reproduces inequality. In analyzing the questionnaire, gender, age, and school type were compared as independent variables with dependent variables related to students' perspectives. Results showed that girls generally hold more egalitarian perspectives than males, older students are more egalitarian than younger students, and students in coeducational schools are more egalitarian than those in single-sex schools. This suggests that coeducation is a step towards gender equality. Furthermore, a comparison between seventh-grade and twelfth-grade students' perspectives in each selected school revealed changes in gender expectations between these two stages, emphasizing the impact of education on enlightening gender equality. However, when comparing students' perspectives with their home background, the impact of the school becomes less apparent. Despite the influence of school or education on gender expectations, home socialization remains the primary factor in increasing or reducing gender inequality.

TEACHER'S COMMUNICATIVE LANGUAGE TEACHING (CLT) STRATEGIES IN IMPROVING THE SPEAKING ABILITY OF THE HOSPITALITY STUDENTS (A CASE STUDY AT SMKN 5 BARRU)

The descriptive study focused on investigating CLT strategies employed by the English teacher in hospitality classrooms to improve the hospitality students' speaking abilities. This research conducted a mixed method design with the quantitative analysis applied in small proportion only to measure the mean score of pre-test and post-test students speaking improvements. The participants in this study involved one teacher and one class from twelfth-grade (XII) students of hospitality at SMK N 5 Barru that consisted of 20 students. Observation with field notes and interviews were used as instruments for data collection. This research utilized Richards's (2006) three practices of mechanical practice, meaningful practice, and communicative practice as the basis in investigating the CLT strategies used by the teacher. The data were analyzed in three major steps such as data reduction, data display, and conclusion drawing proposed by Miles & Huberman (1994). The findings indicated that the English teacher mostly used meaningful and communicative practices rather than mechanical practices. In applying CLT strategies to improve the hospitality students speaking abilities, the teacher mostly provided active discussion activities and worked in pairs or groups with the encouragement of integrating some additional tools such as the online platforms and applications. Moreover, cumulative score analysis from pre-test and post-test verified that the level of speaking proficiency in hospitality students demonstrated a 57.5% improvement, leading to the enhancement in their speaking score, which was classified as moderate categorization. The findings of this study concluded that CLT strategies that applied by the teacher helped improve the students speaking abilities gradually, as these applications also serve the purpose of engaging and captivating students in language learning by encouraging them with opportunities to utilize technological advancements in developing their language skills.

Searching for Consistency in Attendance Data Recording, Reporting, and Utilization in the USA

According to the United States Department of Education (USDOE), 16% or over eight million kindergarten through twelfth grade students in the US missed 10% or more school days during the 2017−2018 school year. This is approximately 18 of 180 days required. We know this because schools are mandated to report their attendance data to their respective states and to the USDOE. There are concerns around accuracy and consistency because each state is allowed to compile data in their own way and report only select metrics to the USDOE to comply with federal guidelines. The consistency on federal metrics, nonetheless, allows for similar analyses at the federal and state levels and comparisons across states. To best understand what is reported, we report on data compiled by the National Center for Education Statistics (NCES) housed in the Institute of Education Sciences, the science branch of the USDOE, and describe how attendance data are collected, reported, and used at the national level. We share similar findings for two representative US states − Connecticut and Indiana − to highlight similarities and differences between them, and their “best practices.” Key results from these multiple levels of analyses are then discussed, with the goal of informing research, practice, and policy related to school attendance, so that students of all ages and from all backgrounds are provided the opportunity to obtain optimal benefits from schooling throughout their school careers.
