Application of Design-Based Learning and Outcome-Based Education in Basic Industrial Engineering Teaching: A New Teaching Method

This paper provides and illustrates a design-based learning (DBL) and outcome-based education (OBE) approach for fostering the innovation, practice, and autonomous learning ability of industrial engineering students. We performed two studies with on industrial engineering students in typical educational activities. The first study used a topic of “sheet metal parts turnover protection optimization” to explore the application effect of “DBL + OBE” and its shortcomings in the implementation process, so as to help students understand this new teaching method. Then, in order to verify the use effect of “DBL + OBE”, the second study used the topic of “production line balance” to divide the students into an experimental class and a control class. The experimental class adopted the design learning teaching method, while the control class adopted the traditional teaching method. In order to verify the effectiveness of the proposed method, students and teachers were interviewed. It was found that the students in the experimental class were more outstanding in personal abilities, such as systematic thinking, independent innovation ability, etc. The results show that: the rational use of design-based learning and outcome-based education concept can stimulate students’ interest in learning, cultivate students’ team spirit, improve students’ innovation ability, practical ability and problem solving ability, and cultivate “innovative talents” needed in the new era.

MiniCP: a lightweight solver for constraint programming

This paper introduces MiniCP, a lightweight, open-source solver for constraint programming. MiniCP is motivated by educational purposes and the desire to provide the core implementation of a constraint-programming solver for students in computer science and industrial engineering. The design of MiniCP provides a one-to-one mapping between the theoretical and implementation concepts and its compositional abstractions favor extensibility and flexibility. MiniCP obviously does not support all available constraint-programming features and implementation techniques, but these could be implemented as future extensions or exploratory projects. MiniCP also comes with a full set of exercises, unit tests, and development projects.

Supervised Learning Applied to Graduation Forecast of Industrial Engineering Students

<p style="text-align: justify;">The article aims to develop a machine-learning algorithm that can predict student’s graduation in the Industrial Engineering course at the Federal University of Amazonas based on their performance data. The methodology makes use of an information package of 364 students with an admission period between 2007 and 2019, considering characteristics that can affect directly or indirectly in the graduation of each one, being: type of high school, number of semesters taken, grade-point average, lockouts, dropouts and course terminations. The data treatment considered the manual removal of several characteristics that did not add value to the output of the algorithm, resulting in a package composed of 2184 instances. Thus, the logistic regression, MLP and XGBoost models developed and compared could predict a binary output of graduation or non-graduation to each student using 30% of the dataset to test and 70% to train, so that was possible to identify a relationship between the six attributes explored and achieve, with the best model, 94.15% of accuracy on its predictions.</p>

El acoplamiento de la manufactura con la pertinencia ambiental como motivador de interés en estudiantes de Ingeniería Industrial

Manufacturing is a key economic activity. Its know-how and its competitive advantages have shaped the history of humankind. In many Industrial Engineering (IE) programs, however, manufacturing is not taught as related to process know-how, but as systemic integration and management. It is possible to capitalize on the recent 3D printing technologies to reintroduce IE students to manufacturing principles through prototyping projects. Sparking the interest of IE students, though, can also be achieved through selecting problems of environmental awareness. This work describes a project of self-assemblies developed under the scheme of undergraduate research that makes prototyping a central endeavor with the aim to foster plastic recycling as an end goal.

Developing Models of Evaluation Through Performance Task Instrument: Its Implementation and Usefulness

Analyzing attitudes of students toward the use of technology for learning: simplicity is the key to successful implementation in higher education

PurposeResearch has shown that the much-anticipated technology revolution in higher education has failed to come to fruition. The arrival of ‘digital natives’ millennial students to higher education was presume to present even greater challenge concerning technology use. In light of these gaps, this research aims to capture higher education students' choice, use and preferences of technology in learning and teaching.Design/methodology/approachA paper-based questionnaire was distributed to third and fourth year students of industrial engineering and management at an engineering college in Israel. The students were asked to indicate their use of devices and technologies for learning, their frequency of use and their purpose of using.FindingsStudents extensively use a variety of technologies for learning. They prefer to use the same technologies for learning that they use in their personal lives – mainstream, commercially available technologies – rather than those offered by the institute. They perceive technology as a learning tool more than as a logistic/administrative tool, they would like technology to be more easily accessible and that it not be used as a facilitator of pedagogical change.Practical implicationsThe results indicate that technologies intended for use in teaching should be designed similar to commercially available alternatives that are simpler to use and more appealing.Originality/valueThis study provides an up-to-date view of students' perceptions of technology for learning that can be used to more effectively implement teaching technologies in higher education.

Website library information system design using fast method

This research was conducted at the Department of Industrial Engineering as part of the department at Sultan Ageng Tirtayasa University which has applied information technology to support every academic activity, information media, and services. Likewise the library which is part of the academic facilities in industrial engineering matters.

Analisis ergonomi pada perkuliahan daring menggunakan smartphone selama masa pandemi covid-19: studi kasus mahasiswa Prodi Teknik Industri Universitas Mulawarman

When Covid-19 emerged in Indonesia in early 2020, students had to learn from home to prevent the spread of the virus. The changing activity could effect on physical and mental health caused by student’s behavior during learning from home. Survey showed that 84% students of Industrial Engineering, Mulawarman University used smartphone while learning from home. Therefore, this study aimed to identify students’ behavior, to measure physical (i.e., musculoskeletal and visual fatique) and mental health (i.e., stress and smartphone addiction) problems that occurred when they were learning from home, as well as to suggest ergonomic recommendation for reducing the negative effects. At the time of the study, they were 155 students studied in the IE department and a total of 134 (86.45%) participated in the online survey. Musculoskeletal disorder was assessed using Nordic Body Map and visual fatique was evaluated using symptoms that were reported on previous studies. Additionally, Smartphone Addiction Scale (SAS) and Perceived Stress Scale (PSS) were administered to identify smartphone addiction tendency and stress level respectively. The results showed that MSD occurred in left and right shoulder (95%), followed by upper neck (82.14%) and back (72.62%). 86% of participants experienced visual fatique with headache (71.55%), ache eye (68%) and dry eye (60.34%) symptoms. Subsequently, this survey revealed that 35% of the participants addicted to smartphone and 68.66% experienced moderate level of stress. To alleviate these physical problems, several ergonomic recommendations were proposed i.e., supporting the arm that holding the smartphone with the other hand, practicing the 20-20-20 rule and applying stop, drop and flop slogan. Moreover, cooperation among parents, students and lecturers was needed to create conducive learning environment so as the mental health problems could be minimized.

Those three variables are simultaneously able to explain the satisfaction variable.

Developing a Multi-Criteria Decision Making approach to compare types of classroom furniture considering mismatches for anthropometric measures of university students.

The mismatch between students' anthropometric measures and school furniture dimensions have been investigated in many countries. In Iran, collegians spend at least a quarter of the day hours at university in the sitting position, so it is essential to evaluate furniture mismatch among university students. In Iranian universities, the use of chairs with an attached table is widespread, while the study of mismatches in these chairs among the collegian community is rare. This study was aimed to compare and rank different classroom furniture types based on the mismatch between collegians' anthropometric measures and the dimensions of classroom furniture among Industrial Engineering students by developing a Multi-Criteria Decision Making approach in an integrated Methodology. The sample consisted of 111 participants (71 males, 40 females). Ten anthropometric measures were gathered, together with eight furniture dimensions for four types of chairs. Mismatch analyses were carried out using mismatch equations, and the Simple Additive Weighting method was used as a base method to solve the decision-making problem. The results indicated that Underneath Desk Height and Seat to Desk Clearance showed the highest levels of the match, while Seat Width presents the highest levels of low mismatch. According to the results, Type 1 and Type 3 were the best current classroom furniture. The Sensitivity Analysis was performed in two ways: changing the weights of criteria in nine scenarios and comparing the results with five other MCDM methods. The proposed MCDM approach can be used widely in furniture procurement processes and educational environments.

Corporate Social Responsibility Practices of Colombian Companies as Perceived by Industrial Engineering Students.

This work describes the perceptions that Industrial Engineering students have regarding Colombian firms' corporate social responsibility (CSR) practices. It also explores the incidence of gender, academic level, work experience and entrepreneurial intention on students' vision. A survey with 70 CSR practices was designed based on previous research. Practices were grouped in ten dimensions: shareholders, customers, employees, suppliers, stakeholders, ethics, environment, legal, human rights and society. A representative sample of 142 students was used. Results show that students perceive a higher commitment of Colombian companies with the shareholders dimension, while a lower with the society, ethics and environmental CSR practices. Work experience and entrepreneurial intention are the only variables affecting the identified perceptions. Thus, as they gain experience, their perceptions become more favorable. On the other hand, potential entrepreneurs have a more critical view on the companies' commitment. Additionally, the fact that the academic level does not impact students' perceptions constitutes a challenge for the academic program, since it is expected that this will affect the vision of future engineers. This is the first study that evaluates perceptions of Industrial Engineering students, who, given their object of study, will be responsible for designing and managing production processes in organizations of the future. Results respond to a specific context (students at a Colombian public university), therefore further research to explore the subject is recommended.

Classroom or pub - Where are persistent peer relationships between university students formed?

This paper discusses the formation of peers in an anonymous higher education setting using a unique data set of industrial engineering students. For identification, we exploit the random assignment of students into groups and student performance before students met. We compare two different settings for potential peer formation: a voluntary freshman orientation week organized by the students’ union and a mandatory group work course. It is only in the case of the group work course that we report persistent impacts on subsequent academic achievement. In line with our theoretical reasoning, peer effects exist between groups of two students who were already similar before.

VALIDITY AND INTER-RATER RELIABILITY OF POSTURAL ANALYSIS AMONG NEW RATERS

Work posture analysis is crucial in observing and reducing work-related musculoskeletal symptoms in the workplace. However, in a developing country, new raters are commonly assigned to conduct postural analysis to save on cost. This study aims to observe the validity and inter-rater reliability (defined as the degree of agreement among different raters) among new raters of three different commonly used work posture analysis methods: Rapid Upper Limb Assessment (RULA), Rapid Entire Body Assessment (REBA), and Ovako Workload Assessment System (OWAS). Fifty industrial engineering students, divided into five groups, who received prior training about the use of the methods, participated voluntarily in this study by observing ten different working postures in five different industries: the tofu, military equipment manufacturing, automotive maintenance and service, cracker, and milk-processing industries. One ergonomics expert also observed the working postures. Validity was observed based on the correlation between new raters’ ratings and the rating of the ergonomics expert. Inter-rater reliability within one group was calculated using the percentage of agreement and kappa value. The result shows high validity of RULA, REBA, and OWAS among new raters. There are insignificant differences in the inter-rater reliability of new raters among RULA, REBA, and OWAS. The implications of the result are discussed.

THE USE OF REQUEST STRATEGIES OF INDUSTRIAL ENGINEERING STUDENTS

The aim of this study is to investigate the types of the request strategy used by Industrial Engineering students as EFL learners. Using qualitative data, this study discusses the use of request strategy in case-based teaching of foreign languages. The participants of the study are 37 Industrial engineering students who learnt English in the second semester. The testing instruments used were discourse completion task. For this aim, a discourse completion test was used to generate data related to the request strategies by each group. Selection of request situation in discourse completion test was based on three social factors of relative social distance, power, and rank of imposition. The participants� responses were analyzed according to the classifications of request strategy by Blum-Kulka & Olshtain. The case study findings indicate that 57% of Industrial Engineering students� responses mostly use conventional indirect strategies, 29.2 % responses are direct strategies, and 13 % responses belong to non-conventional indirect strategies. 49.7 % responses belong to query preparatory.� 17.8 %� responses� are identified as explicit performatives, 10.3 %� responses categorized as want statements, 9.2 % responses classified as strong hints, 6.5 % responses grouped as mild hints, 4.9 % responses recognized as suggestive formulas, and 1.6 % responses indicated as mood derivable. The indirectness is greatly influenced by students� cultural background, which belong to high-context culture. People in high context culture refer to the value cultures placing on indirect communication. A message is understood with a great deal of gesture, facial expressions, tone of voice, eye contact, body language, posture, and other ways people can communicate without using language. The findings of this study may set pedagogical implications for teachers, and learners of EFL therefore conducting a further field investigation is recommended to have in depth exploration�� about request strategies made by EFL Learners.

Analysis of Learning Motivation in Industrial Engineering Teaching in University of Extremadura (Spain)

Motivational orientations predispose and condition behaviour, and determine the degree of assimilation of concepts by students during their training stage. Knowing them allows professors to conduct their lessons in order to favour maximum achievement for students. The objective of this work is to evaluate the motivation that guides the learning process of Industrial Engineering students at the University of Extremadura (Spain). About three quarters of the students present a high motivation for learning; half of them tend to be result-oriented and less than 10% show a high level of fear of failure. Homogeneous groups were formed based on the level of each dimension, and influential teaching methodologies were discussed. Therefore, it is possible to create a context that favors the acquisition of knowledge by students according to their motivations, and thus achieve maximum academic performance from them. The results shown here may be interesting for the design of promotional activities for SDGs in the university context.

Improving Speaking Skill by Using Group Work Method

There are four skills in English and one of the skills that students think is very difficult is speaking. Speaking is the skill that needs more practice and exercise, otherwise speaking fluency cannot be improved. Teacher needs to use different teaching techniques in order to reach all students effectively. The objective of this research is to see whether the method in teaching Speaking English by using the group work technique has a positive effect on the academic achievement of the students at Polytechnic ATIM (ATI Makassar), especially for Agro Industrial Engineering students who studied at the second grade. This research was carried out through class action research where teacher give some materials , apply the method, then give direct testing such as written test to find out how far students understand about the materials after they discussed in group. It is one of the assessment materials. Others assessments are taken from groups’ activities in class room, groups’ presentation, Individual’s interview test and questionnaire. This technique plays a positive role in improving the academic achievement in speaking. The technique can also improve students’ motivation in learning English; develop their Self-confidence and cooperation among students. The finding from questionnaire proves that this method can also be used to improve students’ mastery of grammar in use and motivate students in learning grammar. The method promotes learner autonomy by allowing students to make their own decision in the group without being told what to do by the teacher.
