An exploration of challenges and support when coaches model instruction for teachers

PurposeModeling is a potentially productive activity in which coaches can engage teachers to support teaching and learning (Gibbons and Cobb, 2017). Yet, there is a lack of empirical research that describes how coaches can productively implement this activity with teachers. The overarching purpose of this study was to explore the challenges and support coaches faced while modeling instruction for teachers.Design/methodology/approachTwenty-nine semi-structured interviews were conducted with five coaches and six elementary teachers in two different school districts in the United States. The data were qualitatively coded using a combination of literature-driven and emergent codes.FindingsParticipants identified 16 distinct challenges they faced during coaching cycles involving modeling, and 11 supports that could ultimately enhance the success of the modeled lesson for all involved parties. These challenges and support spanned the broad categories of contextual factors, management and logistics, pedagogical dilemmas and teacher learning.Originality/valueAlthough modeling is a popular coaching activity, researchers have only an emerging understanding of the challenges associated with modeling instruction, as well as the support that can enhance the modeled lesson's success. By having a thorough understanding of such challenges and support, coaches can effectively leverage modeling to support teaching and learning at their schools. Hence, the findings from this study will importantly inform coaching practice, as well as future research directions.

The Effectivenes of Modeling Instruction Learning on Students’ Conceptual Understanding of Rotational Dynamic

Rotational Dynamics is one of the physics topics which is quite difficult for students. Several previous studies showed students’ difficulties on this topic, one of which is the aspect of students’ conceptual understanding. Modeling instruction is the effective approach to improve students’ understanding. This model is in line with constructivist theory and cognitive model theory. This research aimed to examine the effectiveness of modeling instruction that we developed to improve students' conceptual understanding of rigid body mechanics, where the knowledge of particle mechanics serve as anchor or bridging to develop model of rigid body. This research used mixed method with embedded experimental design. It used one group pretest-posttest design and involved 65 students of a high school in Malang as the subject. Data were gathered using test consisting of 17 multiple-choice items with explanation. The students’ scores were analyzed quantitatively using t-test and N-gain to measure the improvement of students’ understanding, while the students' reasons were analyzed qualitatively. The results showed the average students’ score increased from 1.62 to 9.92 with N-gain of 0.54 (in upper medium category). We concluded that the modeling instruction was effective to improve students’ conceptual understanding.

Video Self-Modeling for a Student with Dravet Syndrome: an Intervention Involving Parents During Covid-19 Pandemic in Italy

Video-modeling instruction (VMI) offers several advantages in increased efficiency, control over stimuli presentation, and logistical factors. These characteristics seem to be critical in helping families of individuals with developmental disabilities during the restriction due to the Covid-19 global pandemic in Italy. The purpose of this study was to investigate the effects of video self-modeling (VSM) on three different behaviors of a 12-year-old boy with Dravet syndrome. The boy's mother was instructed to use VMI through the use of role-playing and performance feedback to implement the procedure directly. A multiple baseline design across behaviors was used. The dependent variable was the number of correct responses for each behavior. Results showed that the procedure was effective in increasing the performance of the participant. Considerations were made related to the potential that a telehealth intervention could have in efficiency, sustainability, and parents’ involvement during and after the health emergency.

Where Are You? Young Adults With Autism Calling and Texting Location Following Video Modeling Instruction

The purpose of this study was to evaluate the effects of using video modeling (VM) to teach three young adults with autism spectrum disorder (ASD) and intellectual disability (ID) to independently communicate their physical location via text and phone call. We used a multiple-probe research design across behaviors to evaluate the effects of the intervention. Data indicated most participants required noncontrolling prompts in addition to the VM to acquire and perform the task analysis (TA) steps with accuracy. Yet once participants reached criterion, they independently performed the multistep skills and the newly learned behaviors were generalized and maintained 6 weeks posttreatment. These results extend the potential utility of VM instruction. Implications for research and practical application are discussed.
