Senior high school students’ understanding of mathematical inequality

Mathematics inequality is an essential concept that students should fully understand since it is required in mathematical modeling and linear programming. However, students tend to perceive the solution of the inequalities problem without considering what the solution of inequality means. This study aims to describe students’ mistakes variations in solving mathematical inequality. It is necessary since solving inequality is a necessity for students to solve everyday problems modeled in mathematics. Thirty-eight female and male students of 12th-grade who have studied inequalities are involved in this study. They are given three inequality problems which are designed to find out students’ mistakes related to the change of inequality sign, determine the solution, and involve absolute value. All student work documents were analyzed for errors and misconceptions that emerged and then categorized based on the type of error, namely errors in applying inequality rules, errors in algebraic operations, or errors in determining the solution set, then described. The result shows that there were some errors and misconceptions that students made caused by still bringing the concept of equality when solving the inequalities problem. It made them did not aware of the inequality sign. Students are still less thorough in operating algebra and do not understand the number line concept in solving inequalities. The other factor was giving “fast strategy” to the students without considering the students’ understanding.

Teachers as change agents: social justice theory to practice

Purpose The purpose of this study is to investigate how participation in a multicultural literature course impacted K-12th classroom teachers’ social justice pedagogy and classroom practices one to three years after completion of the course. Design/methodology/approach This study investigated the effectiveness on teacher practices of a graduate literacy course, which was redesigned within a framework of social justice pedagogy by focusing on critical analysis of texts, teacher inquiry and a literacy civic engagement project. The authors interviewed 20 teachers one to three years after they enrolled in this multicultural children and young adults’ literature course. The authors also explored their classrooms and kept a researcher’s reflective journal. Findings The authors describe how participants implemented social justice pedagogy and strategies with their K-12th grade students. Originality/value While many studies look at how teacher education programs integrate social justice education into their programs, few researchers follow their students into the K-12 classrooms to investigate if teachers are connecting higher education course work and theory into practice.

Development Electronic Student Worksheet based on Relating, Experiencing, Applying, Cooperating, and Transferring (REACT) in Introduction to Chemistry and Laboratory

This research aims to development a REACT-based e-worksheet that is feasible to use to stimulate the critical thinking, creativity, collaboration, communication (4C) skills and determine student response. The challenges of a dynamic era require students to have a 4C skills set critical thinking and problem-solving skills; creativity and innovation; communication; and collaboration. One of the tools that can be used in online learning to achieve this goal is to use the electronic Student Worksheet (E-Worksheet) which includes the student's 4C skill values with REACT strategies: Relating, Experiencing, Applying, Cooperating, and Transferring. The research chooses one of the topics in chemistry, which is introduction to chemistry and laboratories. This REACT-based e-worksheet was developed using the ADDIE development model which consists of five stages those are analysis, design, development, implementation, and evaluation. In addition, the study used a sample of 10 students of mathematic and natural science 12th grade MAN 4 Tangerang. Based on the results of validation and student response questionnaires, REACT-based e-worksheet to stimulate students' 4C skills was declared valid and obtained an average percentage of 91.8% with very good criteria.

Motivational Essay - A Useful Tool in Career Choice?

The proposed study is based on a double causality, such as: the need to improve the counselling tools for high school students for the appropriate choice of a career development path; the existence of the category of disadvantaged students from an economic perspective, whose difficulties in choosing a training path for their career have been augmented during the pandemic. Our research provides an analysis of how the motivational essay can be substantiated as a useful tool in career counselling activities, as well as how it can be integrated into counselling approaches for the economically disadvantaged teenagers to choose the academic development path. We have used a mixed research methodology, which complements the peer review approach with the qualitative analysis of a set of motivation essays developed by the 11th and 12th Grade students. The research aims to identify the level of development of self-analysis, self-reflection and self-assessment of motivational factors, which may be decisive in choosing a future career. The essay analysis highlights a series of elements, which reflects the dynamics of the change of motivational resources in the context of the digitalisation acceleration, of the upheavals on the labour market generated by the new social and economic context. The obtained results allow the formulation of conclusions: confirming the need for such an approach; certifying the possibility and usefulness of integrating the motivational essay into the career counsellor’s methodological portfolio and professional counselling approaches; illustrating useful effects and limits of the reflective effort generated during the essay.

’MPower Shows Me Who I Want to Be’: A Qualitative Study of a Youth Purpose Program

<p style="text-align: justify;">Studies have documented widespread academic disengagement in middle and high school students. This disengagement has been tied to a myriad of negative outcomes, including failure to graduate from high school and transition into college and meaningful vocations. Supporting adolescents in cultivating a sense of beyond-the-self purpose is one factor that may combat student disengagement. MPower is a program designed to cultivate beyond-the-self purpose in an effort to promote student engagement and completion of high school (Klein et al., 2019). In a recent quantitative study, MPower participants compared to controls demonstrated a higher GPA, BTS purpose, self-efficacy, and decreased performance approach and performance avoidance goal orientations. In the current qualitative descriptive study, 11th and 12th grade (N=25) students in the Northeastern region of the United States, described their experiences in the MPower program. Three themes associated with the transformative aspects of MPower emerged from focus group data: 1) practice in strategic goal planning, 2) engagement in mentoring relationships, and 3) increased social support within a community. Because fostering youth purpose engenders many promotive and protective factors, these findings hold important implications for implementing similar programs more widely.</p>

Noise Exposure and Use of Hearing Protection Among Adolescents in Rural Areas

Purpose: Noise-induced hearing loss (NIHL) has been found in rural children, potentially due to occupational and recreational noise exposure without consistent use of hearing protection devices (HPDs). However, questions remain regarding the specifics of rural adolescents' noise exposure and use of hearing protection around different types of noise. As such, the purpose of the current study was to provide preliminary results on rural adolescents' noise exposure and use of hearing protection for gunfire, heavy machinery, power tools, all-terrain vehicles (ATVs), and music. Method: A questionnaire was administered to 197 students (seventh to 12th grade) from rural schools in West Texas. Questions were related to noise exposure and use of HPDs for specific categories of noise. Testing was performed at the schools, with an investigator recording each student's responses. Results: Approximately 18%–44% of adolescents reported exposure 12 or more times a year to gunfire, heavy machinery, power tools, and ATVs. Only 1%–18% of the adolescents reported never being exposed to such noise sources. Almost half of rural adolescents never used hearing protection around gunfire, and 77%–91% reported never wearing hearing protection when exposed to heavy machinery, power tools, and ATVs. Conclusions: The current study revealed that rural adolescents are exposed to noise sources that could damage their hearing. However, the majority of rural adolescents do not consistently wear hearing protection. Additional research is now needed to extend these findings by assessing rural adolescents' duration of exposure to different noise sources, in addition to investigating prevention of NIHL in this population.

Exploring the Relationship between Interest in Higher Education and 12th Grade Mathematics NAEP Scores

This study presented a secondary analysis of the National Assessment of Educational Progress (NAEP) dataset. The paper examined if a gap exists between the mathematics scores of 12th-grade public school students who have different levels of interest in higher education. - This study used a quantitative descriptive research design to analyze data from the 2013, 2015, and 2019 NAEP data sets. The findings include (1) the average mathematics scale score of students who complete college entrance exams, ACT/SAT, is higher than those who do not complete these exams. (2) The average mathematics scale score of students who complete the FAFSA is higher than those who do not complete the FAFSA. (3) Students who applied to four-year colleges performed significantly higher on the 12th-grade mathematics NAEP than those who did not. (4) Students who applied to two-year colleges performed significantly lower on the 12th-grade mathematics NAEP than those who did not. (5) Students who perceived a future benefit to mathematics scored higher on the mathematics NAEP. These findings indicate that students who are interested in higher education, particularly four-year education, do have higher 12th NAEP mathematics scores. These findings may provide insight into college preparation and guidance at the high school level.
