Authors: Kurniawati Ayu
Published: August 2018

Angka kematian dan kesakitan ibu hamil, bersalin dan nifas merupakan masalah yang kompleks. Akses masyarakat terhadap persalinan merupakan salah satu faktor penting untuk menurunkan AKI dan AKB. Salah satu strategi yang dapat dilakukan adalah melalui program Jaminan Persalinan (Jampersal). Jampersal merupakan perluasan program jaminan kesehatan masyarakat (Jamkesmas) yang bertujuan meningkatkan akses terhadap pelayanan kehamilan, persalinan, nifas, bayi baru lahir dan KB pasca persalinan yang dilakukan oleh tenaga kesehatan yang kompeten dan berwenang di fasilitas kesehatan dalam rangka menurunkan AKI dan AKB (Kemenkes RI, 2012). Berdasarkan data Laporan e-Renggar yang dikumpulkan oleh Biro Perencanaan dan Anggaran Kementerian Kesehatan (Kementerian Kesehatan, 2017), diketahui bahwa beberapa kabupaten/ kota tidak dapat melakukan penyerapan anggaran DAK nonfisik program jampersal, salah satunya adalah kota Depok. Tujuan penelitian ini adalah untuk mengetahui secara mendalam potret penggunaan DAK non fisik bidang kesehatan program Jampersal di Kota Depok tahun 2016. Penelitian ini dilakukan dengan pendekatan kualitatif dengan melakukan wawancara mendalam. Informan yang diwawancarai adalah pembuat kebijakan di Pusat, penanggung jawab program di Dinas Kesehatan serta pelaksana program di Puskesmas. Instrumen yang digunakan adalah panduan wawancara mendalam dan dilengkapi dengan alat perekam suara. Hasil dan kesimpulan yang didapat  adalah informasi kendala/masalah dalam pemanfaatan dana DAK Non Fisik program Jampersal di Kota Depok pada tahun 2016 yaitu proses penerbitan juknis cukup terlambat, kurang fleksibel dan kurang disosialisasikan, perencanaan dan penganggaran dilakukan secara Top Down tanpa melibatkan daerah, SDM pelaksana program Jampersal di kota Depok sudah cukup berkualitas namun jumlahnya masih kurang memadai, dan implementasi Juknis belum mampu mengakomodir kebutuhan di daerah akibatnya penyerapan dana DAK Non Fisik program Jampersal tidak dapat terserap dengan maksimal.

Published: August 2018

Purpose: Non-communicable diseases are leading cause of the global death, especially from cardiovascular disease, cancers, chronic obstructive pulmonary disease, and diabetes. Prevention and primary detection of non-communicable disease in Indonesia were done through integrated community-based intervention called ‘Posbindu PTM’. Implementation of ‘Posbindu PTM’ needed to be evaluated to determine each component in the non-communicable disease surveillance systems. Methods: This study was descriptive. Respondent were programmer in district health office and programmer in 24 primary health care in Wonosobo. Surveillance system evaluation that used was programs evaluation based on WHO (structure, main function, support function and quality of surveillance system). Results: The weakness of ‘Posbindu PTM’ in Wonosobo were lack of knowledge in the regulation, networking, collaborating, risk factor detecting and reporting; not availability of technical guidebook; low training participant; low monitoring and evaluation activity; also complex reporting system. There was 84% ‘Posbindu PTM’ that had not reported on time and 87,50 % programmer had not done the analysis, interpretation, and dissemination. This was related to the completeness of the report caused too many data that needed to be collected and affect the timeliness of the report. Conclusion: Strengthening ‘Posbindu PTM’ should be done in the reporting system aspect, especially in the timeliness and analysis of the report. Monthly reminder and refreshing in reporting system were done to improve the reporting system aspect.

Authors: Ramadhani Ira Dewi
Published: August 2018

Masalah citra tubuh tubuh sangat rentan terjadi pada usia remaja baik di Negara Barat, maupun Asia termasuk Indonesia. Semakin kuatnya arus globalisasi mengakibatkan ketidakpuasan terhadap tubuh tidak hanya dijumpai pada remaja perempuan, namun juga pada remaja laki-laki. Penelitian di salah satu SMA ternama Kota Semarang menunjukkan 46% siswa perempuan (20% diantaranya mengalami gangguan makan) dan bahkan lebih dari 50% siswa laki-laki (7% ketidakpuasan berat) mengalami ketidakpuasan terhadap tubuhnya. Hal tersebut dapat menyebabkan perilaku pengontrolan berat badan yang tidak tepat maupun kebiasaan makan yang buruk sehingga membahayakan perkembangan fisik dan kognitif pada masa remaja, bahkan berdampak pada kesehatan mental. Tujuan paper ini adalah menunjukkan proses diseminasi informasi terkait cara pencegahan ketidakpuasan tubuh remaja yang dapat dilakukan lebih dini melalui program di Sekolah Dasar. Metode mencakup kajian dua jurnal  dengan tema pencegahan masalah citra tubuh sejak dini yang menggunakan desain studi kuasi experimen dan RCT. Adopsi program pencegahan ketidakpuasan tubuh bernama Happy Being Me berupa edukasi, diskusi, dan role play yang dilakukan selama 3 minggu pada anak SD usia 10-11 tahun hanya berdampak signifikan pada anak perempuan. Sedangkan program Healthy Medilakukan selama 1 bulan pada anak SD usia 8-11 tahun dengan metode serupa namun fokus pendekatannya berdasarkan jenis kelamin menunjukkan hasil yang lebih baik, yaitu anak perempuan maupun laki-laki mengalami peningkatan signifikan pada beberapa aspek citra tubuh. Selain itu, beberapa cara menarik yang digunakan dalam program Healthy Me adalah mempromosikan makanan sehat dan kebiasaan olahraga. Paper ini menunjukkan bahwa program pencegahan ketidakpuasan tubuh akan efektif untuk diadopsi dengan menerapkan metode yang berbeda untuk siswa SD laki-laki dan perempuan. Program ini harus dilakukan berkelanjutan dalam jangka waktu tahunan dengan evaluasi berkala setiap 3 bulan sekali oleh Guru BK atau Wali kelas. Dibutuhkan pula peran dari orang tua siswa untuk mendukung penerapan program.

Published: August 2018

This study was conducted to understand the association between low birth weight and attention deficit hyperactivity disorder (ADHD) in young children aged 36 – 59 months in Sedayu Subdistrict, Bantul District, Daerah Istimewa Yogyakarta. This study used cross-sectional design with a total of 185 children aged 36 – 59 months were selected by probability proportional to size (PPS) sampling technique. This study was located in Sedayu Subdistrict, Bantul District, Daerah Istimewa Yogyakarta. The study was conducted January 2017. Main variables in this study were low birth weight, prematurity, and attention deficit hyperactivity disorder (ADHD). Maternal and child book was used to confirm the birth weight and gestational age data. Abbreviated Conners Rating Scale form was used to detect ADHD symptoms in young children, followed by a psychologist confirmation. Data were analyzed by using descriptive statistics, chi-square test, and multiple logistic regression at 0.05 level of significance. The proportion of attention deficit hyperactivity disorder (ADHD) was 29.2% in this study. Meanwhile, the prevalence of low birth weight (<2500 g) was 8.11% and prematurity (<37 weeks gestational age) was 2.16%. Children with birth weight less than 2500 g were more likely to develop ADHD symptoms (OR: 3.2; 95%CI: 1.09-9.48) compared to children with normal birth weight. On the other hand, prematurity was not associated with ADHD (OR: 0.64; 95%CI: 0.06-6.89). This study concluded that low birth weight was associated with attention deficit hyperactivity disorder (ADHD). However, prematurity was not related significantly with ADHD. Efforts are needed in improving nutrition adequacy for infants and young children, also development stimulation, especially for those born with low birth weight.
Parameter Identification of Nonlinear System on Combustion Engine Based MVEM using PEM
Authors: Badmianto Trigas , Firmansyah Eka , Cahyadi Adha Imam
Published: August 2018

In four-stroke engine injection system, often called spark ignition (SI) engine, the air-fuel ratio (AFR) is taken from the measurement of lambda sensor in the exhaust. This sensor does not directly describe how much AFR in the combustion chamber due to the large transport delay. Therefore, the lambda sensor is used only as a feedback in AFR control "correction", not as the "main" control. The purpose of this research is to identify the parameters of the non-linear system in SI engines to produce AFR estimator. The AFR estimator is expected to be used as a feedback of the main "AFR" control system. The process of identifying the parameters using the Gauss-Newton method, due to its rapid computation to Achieve convergence, is based on prediction error minimization (PEM). The models of AFR estimator is an open-loop system without a universal exhaust gas oxygen (UEGO) sensors as feedback, called a virtual AFR sensor. The high price of UEGO sensors makes the virtual AFR sensor can be a practical solution to be applied in AFR control. The model in this research is based on the mean value engine models (MVEM) with some modifications. The research dataset was taken from a Hyundai Verna 2002 with the additional UEGO type of lambda sensors. The throttle opening angle (input) is played by stepping on the gas pedal and the signal to the injector (input) is set to a certain quantity to produce the AFR (output) value read by the UEGO sensor. This research produces an open loop estimator model or AFR virtual sensors with normalized root mean square error (NRMSE) = 0.06831 = 6.831%.

Authors: Mitchell Scott S.D. , Lim Merlyna
Published: August 2018

Background This article explores the complexity of citizen participation in social media and crowdsourced journalism by utilizing the case of r/SyrianCivilWar, the sub-community of Reddit where users discuss the Syrian crisis.Analysis  In examining the limitations and affordances of the platform, the article identifies features that characterize the r/SyrianCivilWar community, namely: algorithmic driven public discourse, deliberative communication, reflexivity and transparency, and database journalism. These features shape the functioning of the community and have broader implications for citizen crowdsourced journalism projects.Conclusion and implications  The article demonstrates that alternative media practices, such as crowdsourced journalism, are limited in their capacity to reach mainstream consciousness. In the commodified landscape of media, portability—a capacity for complex issues to be distilled into a simple or simplified concept—is made important.Contexte  Cet article explore la complexité de la participation citoyenne dans les médias sociaux et dans le journalisme financé collectivement en recourant au cas de r/SyrianCivilWar, communauté sur Reddit où l’on discute de la crise syrienne.Analyse  En examinant les limites et avantages de la plateforme, cet article identifie certaines caractéristiques de la communauté r/SyrianCivilWar, à savoir : un discours public basé sur des algorithmes, une communication délibérative, la réflexivité et la transparence, et un journalisme de données. Ces caractéristiques influencent le fonctionnement de la communauté et ont des implications plus larges pour les projets journalistiques financés collectivement par les citoyens.Conclusion et implications  Cet article démontre que les pratiques médiatiques alternatives, telles que le journalisme financé collectivement, sont limitées dans leur capacité à rejoindre le grand public. Le caractère commercialisé des médias traditionnels rend importante la portabilité, c’est-à-dire la possibilité de transformer des questions complexes en concepts simples ou simplifiés.

Published: August 2018

The purpose of this case report is to present success and failure outcomes of seven-year follow-up of resin infiltration treatment (RIT) used for the proximal caries of maxillary premolars. Although resin infiltration can be a good option for micro-invasive treatment, long-term follow-up data are not sufficient, and the outcome of this technique can be affected by factors such as technique sensitivity of procedure, patient's caries risk, and depth of caries progression. Therefore, careful case selection, application, and follow-up are needed.
Effect of Calcium-phosphate Desensitizers on Staining Susceptibility of Acid-eroded Enamel
Authors: Kyaw KY , Otsuki M , Segarra MS , Hiraishi N , Tagami J
Published: August 2018

Objective:

To investigate the effect of calcium-phosphate–based desensitizers, Teethmate AP paste (TMAP) and Teethmate Desensitizer (TMD) (Kuraray Noritake Dental, Tokyo, Japan), on the prevention of staining on acid-eroded enamel.

Methods and Materials:

Forty polished enamel samples (4×4×1 mm) from bovine incisors were randomly divided into five groups (n=8). After immersion in 50 mL of 0.5% citric acid (pH 2.5) for 15 minutes to form acid-eroded surfaces, the surfaces were subjected to different treatments with TMAP, TMD, and NaF (0.21% means 950 ppm) for five minutes. Another eroded group was not treated with desensitizer. For the control group, the samples were not eroded or treated. All the samples were stored in artificial saliva (AS) at pH 7.2 for 24 hours at 37°C. The TMAP, TMD, or NaF was reapplied at eight and 16 hours during the 24 hours of storage time. The surface roughness (Sa) was evaluated following ISO 25178 for surface texture using confocal laser scanning microscopy (VK-X 150 series, Keyence, Osaka, Japan) before acid erosion, after acid erosion, and after 24 hours of incubation in AS. Afterward, the color difference was measured with a dental colorimeter (Shade Eye NCC, Shofu, Kyoto, Japan) before and after staining with tea solution.

Results:

One-way repeated measures analysis of variance showed that acid erosion significantly increased Sa (p<0.001). TMAP- and TMD-treated groups exhibited lower Sa values than the NaF group and the no-desensitizer treatment group. The greatest staining was observed in the NaF group and the no-desensitizer group, while the TMAP and TMD groups significantly decreased the formation of stains.

Conclusions:

Acid-eroded enamel increased surface roughness and tended to absorb more stains. However, the application of TMAP and TMD moderated the roughness and thus prevented the formation of extrinsic stains.

ABSTRACTPublic universities in Kenya are operating in an environment which is faced with a lot of competition. This is because over the years the number of Universities has drastically increased and there has been advancement in technology bringing about shortage of talent. Institutions are increasingly looking at talent as a unique asset that can provide sustainable competitive advantage and superior performance. This research sought to establish the influence of talent attraction on organizational performance. The study was guided by Maslows theory. The target population for the study was; managers, academic staff and non-academic staff in campuses of public universities in county government of Nakuru, Kenya. Stratified random sampling and simple random sampling techniques were used to determine the sample of each stratum of various sub population of total sample unit size of 102. Structured questionnaire was used to collect data. The instrument was pilot tested to ascertain the reliability of the research instrument using Cronbach Alpha. The reliability of the research instrument was found to be 0.794 which was considered reliable. The study employed both descriptive and inferential statistics to present and analyze the data. The Statistical Package for Social Science (SPSS) a computer programme for windows aided the data analysis. Â The study established that talent attraction showed strong positive relationship against organizational performance in Public University Campuses in County Government of Nakuru with correlation of (r = 0.640, p < 0.05) . The study recommends that HR departments to be responsive to needs and constantly changing requirements of workforce in order to improve programmes and policies as need may be. It is also important that institutions adopt talent management to improve on its Â performance.

A graph-theoretic model of single point mutations in the cystic fibrosis transmembrane conductance regulator
Authors: Kakraba Samuel , Knisley Debra
Published: August 2018

Cystic fibrosis is one of the most prevalent inherited diseases. This disease is caused by a mutation in a membrane protein, the cystic fibrosis transmembrane conductance regulator (CFTR). CFTR is known to function as a chloride channel that regulates the viscosity of mucus that lines the ducts of a number of organs. The most prevalent mutation of CFTR is located in one of two nucleotide binding domains, namely, the nucleotide binding domain one (NBD1). However, some mutations in nucleotide binding domain two (NBD2) can equally cause cystic fibrosis. In this work, a graph-theoretic model is built for NBD2. Using this model for NBD2, we examine the consequences of single point mutations on NBD2. We collate the wildtype structure with eight of the most prevalent mutations and observe how the NBD2 is affected by each of these mutations.

Authors: Ethiraj Sumathi , Balasundaram Janarthanam
Published: August 2018

The present study was performed to investigate the phytochemical screening, total phenol, tannin content, antioxidant and antibacterial activity from seed extracts of Cucurbita pepo and Cucurbita maxima (Tindivanam). The phytochemical analysis revealed the presence of active ingredients such as steroids, cardioglycosides, phenols, terpenoids, alkaloids and tannins in the seed extract of Cucurbita pepo followed by Cucurbita maxima. Gallic acid (GA), Tannic acid (TA) and Butylated Hydroxy Toluene (BHT) were taken as standard in case of total phenol, tannin and antioxidant activity respectively. Total phenol and tannin content were quantitatively estimated which recorded maximum in Cucurbita pepo (8.37Â±0.2 mg Gallic Acid Equivalents (GAE)/g and 20.47 Â± 0.37 mg Tannic Acid Equivalents (TAE)/g). The seed extracts were evaluated for antioxidant activities by DPPH (1, 1â€“ Diphenyl -2- picryl - hydrazyl) radical scavenging assay. Among the two species with different solvents used, maximum antioxidant activity was found in the acetone seed extract (84.27Â±0.19%) of Cucurbita pepo followed by Cucurbita maxima (67.83 Â± 0.37%). Different concentrations of acetone seed extracts were tested for the anti-bacterial activity against Bacillus subtilis, Bacillus cereus, Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli using the agar disc diffusion technique. The acetone seed extracts of Cucurbita pepo had superior level of antimicrobial activity. The powerful antibacterial effect is attributed to the greater amount of tannins compound in the acetone seed extracts of Cucurbita pepo.
Encounter probability analysis of irrigation water and reference crop evapotranspiration in irrigation district
Authors: Zhang Jinping , Li Jiayi , Shi Xixi
Published: August 2018

Based on the data series of the annual reference crop evapotranspiration (ET0) and the amount of irrigation water (IR) from 1970 to 2013 in the Luhun irrigation district, the joint probability distribution of ET0 and IR is established using the Gumbel-Hougaard copula function. Subsequently, the joint probability, the conditional joint probability, and the conditional return period of rich−poor encounter situations of ET0 and IR are analysed. The results show that: (1) For the joint probabilities of rich−poor encounter situations of ET0 and IR, the asynchronous encounter probability is slightly larger than the synchronous encounter probability. (2) When IR is in rich state or ET0 is in poor state, the conditional joint probability is larger, and the conditional return period is smaller. (3) For a certain design frequency of ET0, if the design frequency decreases, the conditional joint probability of the amount of irrigation water will decrease, therefore the encounter probability of them will decrease. (4) For a certain design frequency of the amount of irrigation water, if the design frequency decreases, the conditional joint probability of ET0 will increase, thus the encounter probability of them will increase.

Authors: Stammitti-Scarpone A. , Passeport E. , Evans G. , Mahadevan R.
Published: August 2018

Abstract – To build awareness in second-year chemical engineering undergraduate students on runaway reaction dynamics and associated safety concerns, and to help students better identify crossovers between two different courses, a combined team project between the Heat and Mass Transfer and Applied Differential Equations courses at the University of Toronto has been implemented. To evaluate the effectiveness of this combined project on students learning, a survey was conducted around four different perspectives: (A) Contribution to learning, (B) Motivation and awareness, (C) Project structure and support, and (D) Personal experience and skills development. The results of the survey demonstrated that the project was effective at bringing awareness about safety issues and the role of students as future professional engineers. It helped them better learn the concepts seen in both courses and develop their team skills. A critical analysis of these results helped to provide guidance for improvement in future years are discussed.

DEVELOPMENT OF PEER TEACHING SUPPORTED DESIGN FOR X MODULES FOR SENIOR ENGINEERING DESIGN PROJECTS
Authors: McSorley Grant
Published: August 2018

Abstract – This paper presents initial results from a series of modules introducing Design for X (DfX) concepts to student project teams. DfX methods are recognised as a means to facilitate decision making throughout the design process and directly support the “Design” graduate attribute as defined by the Canandian Enginering Accreditation Board.

In this senior design course, third and fourth year students are integrated into the same project teams, with the aim of promoting peer learning and leadership.  Therefore, a flipped classroom approach was applied to the modules, followed by team-based reflection and discussion after which the appropriate DfX methods were to be applied within the projects. In the second semester third year students from each team were required to update the class on how these methods had been implemented in their projects.

Preliminary results show active participation by the fourth year students, with varying levels of application of the tools within the projects. This paper will present specific examples of student led discussion and exercises surrounding DfX topics, as well as a qualitative evaluation of the application of DfX methods by the student teams. Recommendations for future improvement include the development of additional short duration, concrete, formative DfX activities for inclusion in the modules.
THREE QUARTERS OF A LOOP: CO-OP WORK TERM EVALUATIONS AND WORK REPORTS TO MEASURE THE COMMUNICATION ATTRIBUTE
Authors: Milne A. , Pirnia M. , Al-Hammoud R. , Grove J.
Published: August 2018

Abstract –This research analyzes the available data (student work term evaluations performed by employers, and work reports evaluated by the program) to triangulate and understand student performance on the CEAB Communication attribute. In this way we aim to innovate in the field of co-operative education to leverage the diverse work experiences of our students and understand their diverse backgrounds to suggest means of improving their communication skills. In this paper, we analyze employer feedback by grouping responses in several ways (binning by engineering program, term of study, level of performance, and criteria) to assess student performances at the faculty and program levels. We also assess student work reports for communication and analytical skills. We find a notable contrast between the evaluations given for the performance criteria. Students appear to perform at a higher level in areas such as Interpersonal Communication, Teamwork, and Appreciation of Diversity, while evaluations for criteria such as Problem Solving and Oral and Written Communication are relatively lower. This is supported by work report assessments showing that some students continue to struggle with written communication and analysis. Future work will include focus groups with employers and students to add meaning to the data. Throughout the process, writing and communication experts are involved to help interpret data and recommend solutions.
WRITTEN ASSIGNMENTS, UNDERGRADUATE LEVELS OF CONFIDENCE AND THE ENGINEERING PORTFOLIO
Authors: Parker Anne , Marcynuk Kathryn
Published: August 2018

Abstract – In this paper, we will summarize some of the results, first, from our course syllabi project that we conducted at the University of Manitoba and, secondly, from our study of second-year students’ levels of confidence in a communication class. In the course syllabi project, we discovered that course outlines in our Engineering school gave little information on the assignments expected of students, so much so that students may have found completing them to be difficult. In the second study, we found that students generally lacked confidence in writing tasks, especially at the beginning of term.  These two studies suggest that we need to find a way to guide students in the writing of the assignments that we expect of them if they are to develop the necessary confidence in their ability to write well within a professional context.

One way to do that may be the introduction of a portfolio requirement within the Engineering curriculum, A portfolio will serve as a record of students’ ongoing achievements in written assignments throughout their academic programs and, as they compile their portfolios, they can reflect on that achievement and move forward – more communicatively competent and more confident.

Abstract – As a continuation of previous research pertaining to the self-assessed effectiveness in various interpersonal aspects by undergraduate Mechanical Engineering students as the Lassonde School of Engineering, the authors present in this paper, the findings of new research elaborating upon areas of concern surmised from the prior study. Motivation for this new research stems from the previous data relating to interpersonal and team relational skills inadequacies and the experiences of this paper, the authors present the findings of new research continue upon previous research pertaining to undergraduate students in Mechanical Engineering program self-assessment of effectiveness. The main objective of this paper is to present upon the common challenges of design team projects according to students, and the influence (or relation) effective and/or ineffective interpersonal relationship skills have upon those challenges. Results from this investigation indicates that human-related challenges experienced in team projects stem largely from ineffective manipulation of communication and relational skills and the various facets of team dynamics directly and indirectly affected by them. Additionally, research indicated that females team members had more gendered experiences with their teams. The author found there to be correlations between the negative female experiences and ineffective relational / interpersonal skills.
ONE-MINUTE QUIZZES TO IDENTIFY POTENTIAL STUDENTS AT RISK IN ENGINEERING COURSES
Authors: Sowinski Andrew , Turcotte Marcel , Arbez Gilbert , Taylor David
Published: August 2018

Abstract – Recent years have witnessed increased interest in reducing student attrition at universities due both to matters of improved student outcomes and the practical fiscal benefits accrued from improved retention.  The reason for student attrition can be due to many contributing factors (maturity, motivation, external stresses, etc.) and may be difficult to predict. Usually the home Faculty (and sometimes even the student) is only aware of risked academic failure at the end of the semester.  At this point it is generally too late for an intervention to be effective.

Although there are numerous intervention models that can be used to help students, these interventions are only effective if students can be identified early in their studies.  One method to address this is to assess all students as frequently as possible and in as many courses as possible to create a map of student academic engagement and performance. This paper focuses on the first phase of a long-term study to create such an early warning system to help find students at risk. The first phase consisted of using one-minute quizzes during classes and general attendance to determine the level of engagement of each student. This data was then used to try to identify students in advance that risk academic failure.

It was found that students who regularly missed 30% of class within the first 5 to 8 classes provided an indication of the likelihood of failure of the student.
LESSONS FROM ENGINEERING PHILOSOPHY
Authors: MacLeod Glenys
Published: August 2018

Current educational literature calls for a shift in educational paradigm from a system of facts and tests to a system of curiosity, innovation and entrepreneurialism. Harvard psychologist Howard Gardner defines intelligence for students today as “the ability to solve problems that one encounters in real life, the ability to generate new problems to solve and the ability to make something or offer a service that is valued in one’s culture” [2]. Engineers in the field are models of learners for life. They have blended content knowledge, skills and competencies into an intuitive engineering sense. Engineers work collaboratively with others knowing that the best possible solution will be a negotiation between perspectives, boundaries and possibilities. They are flexible in their approach to new tasks, they learn from failures and they welcome uncertainty. Engineers are able to assess a situation, identify a component or process that could be improved, gather data, develop ideas, and create something, an item, process or service that is valued. What might education learn from engineering?
AN INSTRUCTOR’S EXPERIENCE OF IMPLEMENTING BLENDED LEARNING IN ENGINEERING: BENEFITS AND CHALLENGES
Authors: Adeeb Samer , Brown Carol , Nocente Norma
Published: August 2018

This paper discusses how a blended learning approach was implemented in two courses in the Civil and Environmental Engineering program at the University of Alberta: CivE 398 (Introduction to Continuum Mechanics); and CivE 295 (Civil Engineering Analysis II). During the blend, two approaches were used to convert content to an online format: first was the development of online videos that were used to complement either in-class or laboratory activities. The second approach was the development of an online textbook (https://sameradeeb.srv.ualberta.ca) with interactive examples which replaced a traditional paper textbook. For each approach, the tools that were used along with the associated costs will be presented. Changes to in-class or lab activities will be also be discussed, along with the associated challenges, and perceived advantages of the blended approach, from the instructor perspective. In addition, the preliminary results of student surveys related
ASSESSING AND DEVELOPING THE INDIVIDUAL AND TEAM WORK ATTRIBUTE

Working effectively in teams is an essential skill that must be developed over the course of an engineering degree program. However, soft skills such as effective team behaviours can be difficult to assess and develop in students. Accordingly, the paper outlines our efforts to operationalize the Individual and Team Work attribute with the intention of outlining best practices in assessing, tracking, and enhancing the graduate attribute for both student development and accreditation purposes.A survey comprised of 40 Likert-scale items and 3 open-ended response questions was administered to all undergraduate students at a large North American university. The survey resulted in key findings, including that students rated their team work competencies significantly lower than they rated the perceived importance of those competencies for success in the workplace. Additionally, females reported significantly lower satisfaction and support in their team experiences than male students. These findings and others resulted in 12 evidence-based recommendations to strategically support the Individual and Team Work attribute.
USING POST COURSE ASSESSMENTS TO INVOLVE INSTRUCTORS IN THE CONTINUOUS IMPROVEMENT PROCESS

Abstract – Continuous improvement is a critical aspect of engineering program development and accreditation. Instructors are important stakeholders who can provide valuable feedback with regards to courses and curriculum; however, obtaining this information can be problematic. Here we present a post course assessment system (PCAS) that enables all instructors to provide timely and specific feedback about their courses as well as pause to reflect on the pedagogical successes and challenges they have faced over the course of a semester. The PCAS also serves a number of program specific uses (triggers, graduate attributes, consistency). The system has been very successful if providing course-based information and, taken in aggregate, program-based insight. The system continues to be adapted but is a good model of instructor engagement and feedback mechanism.
HOLDING THE CRUCIBLE: GROWING A PORTFOLIO OF ENGINEERING LEADERSHIP ELECTIVE COURSES AND A COMMUNITY OF EDUCATORS
Authors: Simpson Annie , Klassen Mike , Reeve Doug
Published: August 2018

Abstract – Engineering leadership programs in Canada have grown in recent years, captured by a literature that mostly documents course design and outcomes. This paper addresses a gap in understanding how courses evolve over time, and how instructors can be better supported to teach engineering leadership. Findings show detailed trajectory of elective course development, instructor profiles, results of learning outcomes mapping, and approaches to supporting a group of leadership instructors.
STUDENT AND FACULTY EXPERIENCE WITH BLENDED LEARNING IN A FIRST-YEAR CHEMISTRY FOR ENGINEERS COURSE

Published: August 2018

Abstract CHE 102, Chemistry for Engineers, is an introductory chemistry course taken by most engineering students at the University of Waterloo during their first term of study. In an effort to create time for more valuable instructor-student interaction and to allow students to explore course content at their own pace, some lecture sections piloted a blended learning model for approximately half the Fall 2016 term. Data from surveys administered throughout the term were combined with course grade data in an effort to compare and contrast student experience, satisfaction and performance between a blended learning and traditional lecture model of instruction. While the results from the Fall 2016 study are inconclusive due to challenges with survey administration and implementing the blended learning model, lessons were learned with respect to the readiness of the students for self-directed learning and the integration of the online and in-class components. We plan on continuing this study during the Fall 2017 term.
Using Role-Playing Simulations to Teach Quality Control in the Design of Medical Devices

Abstract – A simulation is used to facilitate cooperative and team-based learning to introduce concepts of human factors, risk analysis, and quality control applied to the design of medical devices. We further use a friendly game-based approach to simulate the dynamics between a customer, a regulatory agency, and competitive manufacturers. Students are divided into manufacturing teams/companies and teaching assistants act as the customer and regulator. To promote positive interdependence and individual accountability, each student within a company is assigned roles of CEO, inspector, marketer, and designer. The goal for each company is to design and produce as many eye patch medical devices as possible, which must be approved by the regulator, within a tight deadline. Products are evaluated by the customer, who decides what price to pay for each unit, at the end of production. The most successful company is determined by the greatest amount of money earned after two rounds of production and sales.
