The hands-on approach in teaching and learning is an important resource to be explored because it offers a meaningful platform for student-instructor interaction that fosters sound scientific reasoning and improves the understanding of abstract chemistry concepts. Experiment-centric pedagogy (ECP) is a contemporary teaching approach that integrates active student participation in problem-based activities through hands-on mobile devices. This paper describes how experiment-centric pedagogy (ECP) has been used to teach key chemistry concepts to undergraduate students in the chemistry discipline at Historically Black University (HBCU). To assess whether ECP achieves a lasting increase in undergraduate student curiosity and engagement in the chemistry discipline, ECP was implemented from Fall 2021 to Fall 2022 using an inexpensive, safe, and portable electronic instrumentation system usable in both classrooms and laboratories. The Motivated Strategies for Learning Questionnaire developed by Pintrich, Smith, García, and McKeachie in 1991 was used to measure the key constructs associated with students’ curiosity and engagement. The classroom observation protocol (COPUS) was used to assess instructors’ effectiveness, and signature assignments were used to evaluate knowledge gains.

Students' feedback on the use of low-cost, portable and safe hands-on tools in teaching and demonstrating noise pollution at a historically black university
Dynamism of using pedagogy to teach concepts related to noise engineering at undergraduate level can fuel leaners desire to find a career opportunity in the field. This study aimed to investigate the impact of low-cost, portable, and safe hands-on tools used in teaching and demonstrating noise pollution at a historically black university (HBCU). The study was conducted among undergraduate students at one HBCU, and feedback was obtained regarding the device and the pedagogy using a 5-scale Likert questionnaire. The purpose of the study was to improve teaching pedagogy by assessing the impact of the tools on teaching and learning. The feedback from the students showed that the tool was well accepted and provided learners with an advantage in understanding noise pollution. Additionally, the engagement of students in class improved as a result of the use of the tool. The findings suggest that the use of low-cost, portable, and safe hands-on tools can enhance the teaching and learning of noise pollution and other related topics. This study highlights the importance of evaluating teaching and learning pedagogy to improve the quality of education.

Learning critical concepts that are centered on the analysis, design, and maintenance of transportation infrastructure systems poses a measure of difficulty for undergraduates in engineering. Therefore, hands-on learning pedagogy should be an excellent precursor to increase understanding of these concepts, since the pedagogy incorporates real-life experience in the delivery. This paper describes how a hands-on learning pedagogy called experiment-centric pedagogy (ECP) has been used to teach these concepts to undergraduate students at a historically Black university. The research questions are as follows: (1) How well can ECP improve students’ understanding of concepts essential to the analysis and design of transportation infrastructure systems? (2) How has the ECP facilitated the achievement of the learning objectives of these concepts? and (3) Does an ECP increase the engagement of undergraduate students in their transportation infrastructure engineering learning and lead to measurable lasting gains? To answer these research questions, ECP was implemented and assessed when used to teach the concepts of stress and strain utilized in the analysis of bridges and other transportation infrastructure, sound used in the development and design of noise barriers, moisture content in controlling compaction of highway infrastructure systems, and degradation of infrastructure systems exposed to various environmental settings. Assessment results from 92 undergraduates reveal an increase in students’ motivation and cognitive understanding of the relevant concepts, as well as learning gains and an improved success rate compared to the traditional method of teaching.more » « less

Noise engineering is not a new field of study, but statistics showed that experts in the field are on a decline. Observing that motivation and curiosity are among the hallmarks of any workforce development pipeline, the study developed an experiment-centric pedagogy to detect and measure noise from pollution using low-cost hands-on devices with the aim of motivating learners. The study design was a pre- and post-test method. The learners were enrolled in a transportation course and the noise detection and measurement strategies course module was used for the study. Motivated Strategies Learning Questionnaire was adopted for the study. Learners’ response to the use of technological tools incorporated in learning was predominantly positive revealing that the learners’ gain extensively. More so, significant improvement was observed in the task value and expectancy component of leaners (p<0.05) and overall, there was an increase in their motivation at the posttest. Significant improvement in academic performance of learners was also observed at post-test (p<0.05). It is therefore posited that there is need for effective engagement with learners with similar low-cost hands-on to lead to better understand and motivation that can lead to development of workforce in noise engineering.more » « less

A cost-effective, secure, and portable electronic instrumentation equipment is used in Experiment Centric Pedagogy (ECP), formerly known as Mobile Hands-On Studio Technology and Pedagogy, as a teaching method for STEM subjects both inside and outside of the classroom. Since the Spring of 2020, ECP has been integrated into two Industrial Engineering (IE) courses: Thermodynamics and Materials Engineering. This has been done in various ways, including through student use at home and in-class demonstrations and teaching labs. During the most recent academic session (Fall 2021–Spring 2022), the effects of practical home-based experimentation and lab activities on students' attitudes, interests, and performance were examined for the Engineering Thermodynamics course. The outcomes of a survey known as the Motivated Strategies for Learning Questionnaires (MLSQ), which was given to 51 students, demonstrated better improvements in the student's motivation, epistemic, and perceptual curiosity, three crucial characteristics linked to their success. Along with the MLSQ, the Classroom Observation Protocol for Undergraduate Students (COPUS) assesses active learning in Industrial Engineering courses, and quantitative and qualitative data on the significant components of student achievement were gathered. Results obtained show that using ECP has improved students' awareness of material properties and increased their interest in learning about the thermodynamics concept of heat transfer in connection to various solid materials.more » « less
