We present a spreadsheet-assisted exercise using Microsoft Excel software for the<br>determination of the universal gas constant, R, in 35,712 different units. This large<br>number of units arises from a simple enumeration of possible pressure-volume unit<br>combinations and energy unit combinations covering SI (metric), Imperial (British), and<br>American units. In turn, various units for force and area used for defining pressure, and<br>various units for force and distance used for defining energy are explored. This<br>presentation serves as an excellent exercise for high school and undergraduate students to<br>master the skill of dimensional analysis, unit conversions, and basic combinatorics in<br>general chemistry and physical chemistry courses. Instructors can also use the described<br>exercise of constructing conversion matrices to train students in how to efficiently use the<br>Microsoft Excel spreadsheet program.

Cheating on tests is a serious problem in education. The purpose of this study was to test the efficacy of a modified form of the theory of planned behavior (TPB) to predict cheating behavior among a sample of Saudi university students. This study also sought to test the influence of cheating in high school on cheating in college within the framework of the TPB. Analyses were conducted on a sample of 322 undergraduate students using structural equation modeling. The results were consistent with the TPB model’s predictions. The TPB model explained a modest variance in cheating in college. When cheating in high school added to the model, the proportion of explained variance increased and cheating in high school was the best predictor of cheating in college. Although not hypothesized by the TPB, subjective norm had a direct effect on attitude.

Street foods is one of common food for undergraduate students. There are many contaminat wich can contamined street foods, such as biological, phisical, and chemical contaminant. Many health problem can be caused by contaminated food. The purpose of this reseach is to indentify chemical contaminat in street foods that is sold in front of Siliwangi University, Siliwangi street. This research is using survey method with 37 sample of street foods that are taken from 18 food�s seller. Chemical contaminant was indetify using food contaminat detection kit. Individual factor such as education, age, and income and also who is the producer of streets were also measured in this study. Univariat analysis use the frequency distribution table, graph, and statistical calculation values. The result of this research are most of the responden�s education are yunior high school and senior high school. Average of respondens are 35 years old, and daily income are Rp 314.000,00. Most of the street foods is produced by the own seller. Chemical contaminat detection showed borax and Rhodamin B aren�t detected. But formalin is found in two street foods. The recomendation are continue monitoring and ecducating food street�s seller abaout the impact of using chemical food additives.

AbstractThe impact of demoralization among the general population has received little attention due to the lack of an appropriate measurement. Three studies involving 1,143 high school and undergraduate students in Taiwan were thus conducted to develop and validate a tool to assess demoralization. A pool of 50 items was first developed and administered to high school students. Exploratory factor analysis results supported a 5-factor solution with 15 items (Study 1). Study 2 compared the potential models using confirmatory factor analysis and found the 5-factor second-order model with 15 items the best fit model. The 15-item Mandarin version of Demoralization Scale (DS-M-15) was also found to have good internal consistency, test–retest reliability, and (concurrent and predictive) validity in a sample of undergraduate students (Study 3). Taken together, the converging findings show that the DS-M-15 is a promising tool for assessing demoralization among Chinese adolescents and emerging adults.

Arizona State University has been involved in identifying the future Facility Manager (FM) paradigm which results in a sustainable FM profession. The $16M, 20-year international research program has identified, created and tested out a solution to the almost impossible task of replacing the aging FM professionals. The research has identified the future FM as one who is leadership based and leads the entire supply chain from inside the organization. This paper will cover the three year results of finding the future FM by accessing the top 10% of ASU’s 85,000 students through Barrett’s Honors Program, 7th – 10th graders through the Barrett’s Summer Honors Program, and culminating this year in placing the education in one of the top private schools in the state of Hawaii for high school students, testing the approach on 116 Brazilian engineering undergraduate students and getting approval for testing a 14 week program in the Tempe High School. The model is proposed as a prototype for future FM professionals and how the FM professional can become sustainable.

Previous research has reported that many high-school and undergraduate students have difficulty explaining the relationship between polarity and electronegativity even though they may be familiar with the concept of polarity. This study aims to address these misconceptions using a leaflet and assess its effectiveness using questionnaires and concept testing.  A simple, colorful printable leaflet was produced and distributed to students in Indonesia. The Leaflet on Electronegativity (LoEN) provided students with an overview of the theoretical basis of the concepts and guidance on applying these principles. The leaflet format is cheap and easy to mass-produce, which is an important factor given the limited access to other types of appropriate learning resources in Indonesia. The leaflet formed the basis of a classroom discussion activity. Visualization is known to play an important role in constructing students' conceptual understanding, so the leaflet made extensive use of diagrams to explain relevant concepts. The leaflet was printed in full color to make it visually appealing and facilitate student learning. Students were tested before and after learning with the LoEN. A Paired-sample t-test using SPSS is used to compare the pretest and posttest scores to measure the effectivity of the LoEN.A statistically significant improvement in scores (p = 0.000) was achieved, which indicates that using the LoEN in the classroom helps students understand the topic. Also, students' positive responses signify that the LoEN provides an engaging way to learn the concepts.

The first language (L1) usage is still found during the English lesson, specifically in non-native English countries. This may be a debatable issue among experts. Hence, investigation on students’ perception is helpful in this study. It will give an insight into students’ preferences for learning the language. The previous studies related to this topic were mainly focused on senior high school and undergraduate students as the subject. Therefore, this present study proposed to explore the perception of junior high school students. In conducting this study, the researcher applied a quantitative survey design. There were 29 questions in three sections that were distributed to investigate: (1) the language used in the EFL classroom, (2) students’ attitudes as well as (3) students’ well-being during the English foreign language lesson. The participants were 101 students of SMP Shalahuddin Malang. The findings revealed that students have positive responses towards the use of Indonesian langauge during the EFL lesson.   DOI: 10.26905/enjourme.v6i2.6701

Abstract The paper presents the topic of academic education for sustainable development (ESD). A diagnostic survey was made in a form of a questionnaire in three groups of respondents: active geography teachers, participants of postgraduate program preparing for teaching geography and undergraduate students majoring in geography. The conducted research revealed how the groups of respondents differ in regards perception and preparedness to use of SD and ESD in school geographical education
