Evaluating student learning in large introductory biology courses: predictors of student success and lessons for course redesign

In 2009, the University of Calgary began an extensive redesign of its first-year biology courses based on survey feedback from both students and faculty, as well as the extensive literature showing the effectiveness of student-centered pedagogies in enhancing student learning, engagement and retention in large classes. The two newly designed courses, Energy Flow in Biological Systems and DNA, Inheritance and Evolution are concept-based courses that emphasize the integration of key concepts from biomolecules to the biosphere within a student-centered learning environment; these courses begin in Fall 2011. In order to understand the factors influencing student success in first-year biology, we have initiated a three-year mixed-methods investigation of students’ a priori knowledge, motivations, and approaches to learning. In our current first-year courses, we collected data related to changes in both student motivation and learning over the entire first year for 750 students. The strongest predictors of student success, based on grades earned in the lecture component of the course, were multiple-choice pre-test scores (

Less Traditional – More Conceptual: Enhancing Student Learning in First-Year Biology

Over the last two decades, a number of influential reports have called for fundamental changes to undergraduate science education. Most importantly, these reports advocate a shift from traditional lecture-based teaching formats to ones that use student-focused pedagogies to encourage deep student learning about key conceptual ideas in science. Based on these reports, and the underlying research, the University of Calgary completed an extensive redesign of its first-year biology courses in 2011, resulting in two courses: Energy Flow in Biological Systems and DNA, Inheritance and Evolution. These courses focus student learning on two foundational concepts and use student-centered pedagogies to encourage the development of critical-thinking and problem-solving skills. Pre/post data collected from one year of the previous introductory courses and two years of the redesigned courses were used to determine the impact of the transition to a conceptual-based curriculum and the incorporation of active learning strategies including clickers and in-class group assignments on student learning gains measured via normalized change using questions from Biological Concept Inventory, Respiration and Photosynthesis Diagnostic Question Clusters and the Conceptual Inventory of Natural Selection. Student motivations and approaches for learning (e.g. deep versus surface approaches) using the published Approaches and Study Skills Inventory for Students (ASSIST) survey and the Experiences of Teaching and Learning Questionnaire (ETLQ). Data show significantly higher learning gains during the two consecutive years of implementation of the redesigned courses than those achieved in the previous format. Additionally, students reported that lecture activities allowed them being more engaged with course content. We are currently analyzing student written responses, which will provide further insight into the impact of course redesign on content knowledge and critical reasoning skills on student success

Assessing the Need and Receptivity for an Integrated Healthy Sexual and Dating Relationships Intervention for Community College Students

Background: In emerging adulthood, youth often become involved in more serious romantic relationships. However, many lack the skills to avoid an unplanned pregnancy or sexually transmitted infection (STI), and to ensure a healthy dating relationship. Community college students serve nearly half of all undergraduate students in the United States; yet, community colleges typically lack resources for sexual health promotion. Purpose: To assess the need and receptivity for a web-based integrated healthy sexual and dating relationships intervention among community college students. Methods: In summer 2016, we partnered with three community colleges in South Central Texas to conduct an online survey of students’ sexual behaviors and dating relationships, and usability testing of activities from an integrated, web-based healthy sexual and dating relationship intervention. Results: Online survey participants (n=271) were 70% female, 38% Hispanic, 24% White, 17% Black, and 16% Asian; 20% self-identified as sexual minority; mean age was 20.8 years (SD = 2.05). Participants reported high rates of sexual risk behavior including sex without a condom or an effective birth control method, low use of long-acting reversible contraception, frequent use of emergency contraception, and low use of dual protection to prevent pregnancy and sexually transmitted infections. Two-thirds reported experiencing any type of dating violence perpetration or victimization in the past year. Usability testing participants (n=14) were 86% female, 42% Hispanic, 50% Asian/Pacific Islander, 14% Black, and 7% White; 71% were sexually experienced; mean age was 20.7 years (SD = 1.64). The web-based activities were highly rated in terms of usability parameters, and positively impacted short-term psychosocial outcomes related to condom use, accessing contraceptive health services, and constructive interpersonal conflict resolution. Conclusion: Findings underscore the high need and receptivity for an integrated healthy sexual and dating relationship web-based intervention among community college students, an understudied subgroup of youth in emerging adulthood

An empirical assessment of innovation practices of quantity surveying firms in Ghana

Innovation is ascertained to be a major driver of growth of the productivity of a firm. This has spurred the interest of many researchers to study and harness the adoption of innovation. Extant literature indicates that some professional services offered by the quantity surveying (QS) firms are not needed by the client, or may be outdated. Consequently, the QS firms have to develop the stamina to challenge the existing unnecessary and unwanted or outdated practices and implement innovative practices. What is more alarming is that the QS firms are rated to have a low disposition towards the adoption of innovation. This established context propelled the need for empirically assessing the innovation practices amongst the QS firms in Ghana. A quantitative research approach was employed for this study and a census sampling technique was adopted. A total of 43 questionnaires were administered to the entire population and 24 were retrieved. The current level of innovation practices amongst the Ghanaian QS firms was interpreted using Rogers’ innovation diffusion theory. The results indicated that QS firms in Ghana are early adopters of process innovation, product/technological innovation and business system innovation. The study showed that QS firms adopt innovation practices in rendering their services and even though they do not initiate new ideas, they are the first to adopt the ideas initiated by the innovators. This study has drawn attention to the assessment of innovation practices and increasing the knowledge base of innovation practices in Ghanaian QS firms

Development of 3-D Ice Accretion Measurement Method

A research plan is currently being implemented by NASA to develop and validate the use of a commercial laser scanner to record and archive fully three-dimensional (3-D) ice shapes from an icing wind tunnel. The plan focused specifically upon measuring ice accreted in the NASA Icing Research Tunnel (IRT). The plan was divided into two phases. The first phase was the identification and selection of the laser scanning system and the post-processing software to purchase and develop further. The second phase was the implementation and validation of the selected system through a series of icing and aerodynamic tests. Phase I of the research plan has been completed. It consisted of evaluating several scanning hardware and software systems against an established selection criteria through demonstrations in the IRT. The results of Phase I showed that all of the scanning systems that were evaluated were equally capable of scanning ice shapes. The factors that differentiated the scanners were ease of use and the ability to operate in a wide range of IRT environmental conditions

Riparian Zone Nitrogen Management through the Development of the Riparian Ecosystem Management Model (REMM) in a Formerly Glaciated Watershed of the US Northeast

The Riparian Ecosystem Management Model (REMM) was developed, calibrated and validated for both hydrologic and water quality data for eight riparian buffers located in a formerly glaciated watershed (upper Pawcatuck River Watershed, Rhode Island) of the US Northeast. The Annualized AGricultural Non-Point Source model (AnnAGNPS) was used to predict the runoff and sediment loading to the riparian buffer. Overall, results showed REMM simulated water table depths (WTDs) and groundwater NO3-N concentrations at the stream edge (Zone 1) in good agreement with measured values. The model evaluation statistics showed that, hydrologically REMM performed better for site 1, site 4, and site 8 among the eight buffers, whereas REMM simulated better groundwater NO3-N concentrations in the case of site 1, site 5, and site 7 when compared to the other five sites. The interquartile range of mean absolute error for WTDs was 3.5 cm for both the calibration and validation periods. In the case of NO3-N concentrations prediction, the interquartile range of the root mean square error was 0.25 mg/L and 0.69 mg/L for the calibration and validation periods, respectively, whereas the interquartile range of d for NO3-N concentrations was 0.20 and 0.48 for the calibration and validation period, respectively. Moreover, REMM estimation of % N-removal from Zone 3 to Zone 1 was 19.7%, and 19.8% of N against actual measured 19.1%, and 26.6% of N at site 7 and site 8, respectively. The sensitivity analyses showed that changes in the volumetric water content between field capacity and saturation (soil porosity) were driving water table and denitrification

Critical drivers for the adoption of wearable sensing technologies (WSTs) for construction safety monitoring in Ghana: A Fuzzy Synthetic Analysis

Purpose: The construction industry is one of the most hazardous working environments globally. Studies reveal that wearable sensing technologies (WSTs) have practical applications in construction occupational health and safety management. In the global south, the adoption of WSTs in construction has been slow with few studies investigating the critical drivers for its adoption. The study therefore bridges this gap by investigating the factors driving WSTs adoption in Ghana where investments in such technologies can massively enhance health and safety through effective safety monitoring. Design/Methodology: To meet the objectives of this study, research data was drawn from 210 construction professionals. Purposive sampling technique was used to select construction professionals in Ghana and data was collected with the use of well-structured questionnaires. The study adopted the Fuzzy Synthetic Evaluation Model (FSEM) to determine the significance of the critical drivers for the adoption of WSTs. Findings: According to the findings, perceived value, technical know-how, security, top management support, competitive pressure, and trading partner readiness obtained a high model index of 4.154, 4.079, 3.895, 3.953, 3.971, and 3.969, respectively, as critical drivers for WSTs adoption in Ghana. Among the three broad factors, technological factors recorded the highest index of 3.971, followed by environmental factors and organizational factors with a model index of 3.938 and 3.916 respectively. Implications: Theoretically, findings are consistent with studies conducted in developed countries, particularly with regard to the perceived value of WSTs as a key driver in its adoption in the construction industry. This study also contributes to the subject of WSTs adoption and, in the case of emerging countries. Practically, findings from the study can be useful to technology developers in planning strategies to promote WSTs in the global south. To enhance construction health and safety in Ghana, policymakers can draw from the findings to create conducive conditions for worker acceptance of WSTs. Originality/Value: Studies investigating the driving factors for WSTs adoption have mainly centered on developed countries. This study addresses this subject in Ghana where studies on WSTs application in construction process is uncommon. It also uniquely explores the critical drivers for WSTs adoption using the Fuzzy Synthetic Evaluation Model
