Learning Outcomes for Environmental and Sustainable Development Component in the Field of Civil Engineering

The Department of Civil & Structural Engineering (JKAS), Faculty of Engineering & Built Environment, has prescribed program outcomes (POs) that include environmental and sustainable development components (ASPL) to meet the requirements put forth by the Engineering Accreditation Council (EAC). Two programs are offered to students: the Civil & Structural Engineering Program and the Civil & Environmental Engineering Program. Therefore, the relevant courses are compulsory to prepare the Course Outcomes (COs) in accordance with teaching plans and to measure to what extent students have achieved the specified POs. This paper discusses the assessment and relationship between COs and POs for the ASPL component made within three specific courses at JKAS, which aims to determine the suitability of the ASPL component by correlating measurements of COs and POs of related courses. It is important to develop the best possible ASPL component measurement model for both study programs offered in JKAS.


Introduction
Sustainable development is a concept that emphasizes the conservation and preservation of natural resources.It is comprehensive and is therefore not limited to certain activities, and it is closely related to the continuation of human life on earth.Sustainable development concerns three primary categories: economic, social, and environmental.These three elements are interconnected to create security, harmony, and prosperity.Sustainable development seeks to balance human needs and demands with the environment's capacity to cope with human consumption and industry.Today, environment and sustainable development component (ASPL) is an important curricular component in higher education, which aims to create human capital that meets the needs of the job market and works to preserve the earth's finite resources.It covers all areas of education.Our country needs engineers, scientists, and those who are experts in various fields to jointly assist in sustaining national development, which not only depends on the earth's resources but also on worker's skills and expertise to preserve those resources.How can ASPL education achieve its desired goals, and how can we measure its effectiveness?Discussions concerning APSL in tertiary education are being held at the national and international levels.Keene and Blumstein (2010) argue that changing environmental education requires the cooperation of various organizations and academic disciplines.
The National Higher Education Strategic Plan, which was launched in 2007, prioritizes the transformation of higher education.The plan aims to achieve excellence and sustainability in higher education beyond the year 2020 (Ministry of Higher Education, 2011) and outlines seven main foci related to that goal.Among the plan's stated goals is the effort to improve the quality of teaching and learning to produce innovative and ethical individuals with the capacity to think critically and who are committed to a common moral standard.To this end, educational practice has been transformed to focus on outcomes.Outcomes-based education (OBE) endeavors to improve the quality of teaching and learning to meet or exceed international standards.For example, to achieve international recognition of credit equivalency, engineering programs in Malaysia must meet certain standards before the country is offered membership in an agreement such as the Washington Accord.According to the OBE approach, the measurement of student learning outcomes is needed to determine students' competencies and cumulative grade point averages (CGPA) for each semester.There are various approaches being used by educational institutions in Malaysia to improve the evaluation of student outcomes.Among them is the development of an electronic evaluation system (Aishah, 2010).1) Understanding of the principles of design for sustainable development.
2) Understanding of the social, cultural, global and environmental responsibilities of a professional engineer.
The Department of Civil & Structural Engineering (JKAS) has outlined 10 program outcomes (POs) that must be achieved by students (Table 1) and two components related to the environment and sustainable development in the PO3.Each course has a specified expected course outcome (CO), and each CO contributes to the achievement of its program's required outcomes (POs).The method for measuring the COs and POs in JKAS is still being improved to suit the needs of each course.Table 1 shows that the outline in PO3 is only for courses in civil engineering design and structure, or civil engineering and environment with environmental constraints and sustainability.Thus, there are courses that do not have an outline in the POs as additions to the environment and sustainable development.This paper discusses examples of PO3 made for the evaluation of three JKAS courses offered in the 2010/1011 sessions: KKKH4284 Sustainable Urban Planning; KKKH4254 Project Design II; and KKKW4024 Pollution Control.This aim is to determine the suitability of PO3 assessment COs for related courses.Evaluations of COs and POs attracted the attention of the EAC panel during their 2010 assessment visits.Therefore, the method for measuring COs and POs must be improved to better assess student achievement.
Of course, students' successful achievement of COs and POs reflects well on an institutions' teaching practices, but this is not the main goal of the assessments.Indeed, the primary aim is to produce graduates who are prepared to help the country continue national development by sustainable means.ASPL teaching and learning in UKM does not take place solely in class but is also included in outdoor activities related to the daily lives of students who seek to enhance their awareness of environmental conservation and sustainable development (Shahrom et al., 2011).

KKKH4283 Sustainable Urban Planning
This course is an elective course, available to students in both programs, which aims to foster comprehension of the core concepts related to sustainable urban planning, as outlined in Agenda 21 (Faculty of Engineering & Built Environment, 2010).It covers the fundamentals of urban design in the eastern and western hemispheres.
Students are also introduced to the use of modern tools in urban planning, for example, layers and satellite technology in mapping.Table 2 shows the relationship between POs, domains, and indicators used to determine the PO assessment for this course.Table 3 shows a complete assessment of this course, which takes into consideration the COs and POs, domains, indicators used, and the method of assessment (assignment-15%, project-40%, and final examination-45%).While Figure 1 shows the use of cognitive domains (K), Affective (A) and Psychomotor (P) are based on the level of 1 to 6 following types of domains such as those used in Table 2. 2) Ability to assess the best practice in sustainable urban planning (CO2) 3) Ability to produce and present a proposal of an existing traditional urban development for a period of 30 years based on the concept of sustainable cities (CO4) Evaluation and measurement conducted in this course shows that CO1, CO2, and CO4 contributed to the achievement of PO4 measurements involving assignments and projects.CO4: Ability to conduct the design and preparation of drawings using the relevant computer software(Excel, AutoCAD, and other design software) PO6 CO5: Ability to produce a report containing an executive summary, introduction, distribution of tasks, concepts, design calculations, drawings for bids, conclusion, etc.

PO7
CO6: Ability to present results verbally to the supervisor and examiner.PO7 CO7: Ability to perform tasks individually and to be an effective team member.

PO8
CO8: Ability to prepare bills of quantities(BQ) and the estimated cost PO10 Each group is given architectural drawings and relevant information to adjust the ASPL requirements to the design components of these projects.This course meets the 8 CO and 7 PO, as shown in Table 4. Overall evaluation of this course takes into consideration the report design, report bills of quantity (BQ); presentation of the project (evaluated by an internal and external examiner); and peer assessment.Internal and external examiners evaluate the students' performance in relation to PO3 involving the ASPL component by evaluating the students' design and presentation of project reports.Table 4 and 5 shows that the course includes components that relate to PO3 and CO2; it is therefore possible to measure the students' achievement in regard to ASPL components.Table 5 shows the breakdown of scoring for the CO2 and PO3 for each method of valuation determined by their weight measured.Weightage for CO2 and PO3 are fixed by 0.2 for the design of reports and 0.25 for presentation, respectively (internal examiner and external examiner).

KKKW4024 Pollution Control
This course is an elective course for both the JKAS program, and it is intended to give students the knowledge and understanding of the principles of preventing pollution from industrial activities, products that are environmentally friendly, and processing systems and manufacturers (Faculty of Engineering and Built Environment, 2009).Students need to understand the impact of waste from these activities and identify the methods of disposal, complete a product life cycle assessment, and understand the principles of sustainability.
The ASPL component in this course relates to CO1, CO2, and CO3 with PO3.Students are divided into groups of 3-4, and each is assigned a different PBL project title involving environmental management case studies by industry/factory.Table 6 shows the relationship between COs and PO3 with the ASPL component.Assessments are based on the PBL project reports, which contributed 30% to the overall course marks.

PO3 PBL Project Report
CO2.Understand the principles associated with planning, design and engineering analysis of some elements in the environment such as life cycle assessment, environmental impact assessment and sustainable development.

PO3 PBL Project Report
CO3. Understand the responsibilities as an engineer and awareness of environmental issues and the need for sustainable development.

Issues Highlighted for Improvement
The comparative analysis of the three courses discussed in this paper related to the measurement of COs and POs, which emphasized the ASPL component.Inclusion of the ASPL component is considered to be the initial step to be taken to improve teaching and learning in engineering programs.The ASPL component is designed to ensure that students learn to apply the concept of environment and sustainability in their work.Issues to highlight include the following: 1) Should the PO3 change to limit the ASPL components in civil engineering design / environment as to adapt to all courses?
2) Measurement between the COs and POs are different between each course; should it be standardized for the entire course?
3) Each evaluation is very time consuming and requires comprehensive work in terms of domain, indicator, COs, and POs.Can this be implemented by the lecturers?Should certain courses be linked to a specific PO only?4) Does the measurement of COs and POs accurately reflect student achievement as outlined in the objectives of the civil engineering program?
Regarding to improve CO and PO assessment, System of Assessment Plan for Educational Program (SP3P) was introduced in UKM to evaluate the CO and PO achievement starting with Semester 2 Session 20112012.Figure 2 shows how the SPS3 system is used for CO and PO assessment.

Conclusion
Based on the measurement of COs and POs for ASPL components in the three courses, it shows that there are differences in valuation carried out.Measurement of the ASPL component conducted in the KKKH4283 Sustainable Urban Planning course is through assignments and PBL project reports as outlined in PO4, KKKH4254 Course Design Project II is through the integration of project reports and presentations as outlined in PO3, while KKKW4024 Pollution Control courses are evaluated through the PBL reports project as outlined in PO3.The issue of accuracy and suitability on the performance measurement of the COs and POs for ASPL components in each course in JKAS needs to be discussed thoroughly with the full involvement of lecturers to develop the best measurement model for the Civil & Structural Engineering Program and Civil & Environmental Engineering Program.
