Abstract

Purpose:

This study examines the perspectives of augmentative and alternative communication (AAC) professionals on the impact of participation in a professional learning community (PLC) focused on delivering AAC services to bilingual children. Specifically, it investigates the professionals' perceptions on (a) their professional development, (b) the learning environments in which they work, and (c) the families and children they serve.

Method:

Over a period of 10 months, a PLC was formed with 15 AAC service providers who work with bilingual users of AAC in educational settings in the United States. Using an action research framework, the PLC engaged in iterative cycles of goal setting, action, observation, and reflection. Data were collected through recorded online PLC meetings and reflective questionnaires. Thematic analysis was used to analyze participants' perspectives on the impact of the PLC.

Results:

Participants described changes in their professional development, including increased focus on accountability, shifts in mindset, and confidence in advocating for bilingual AAC. Changes were also noted in learning environments, with reports of staff becoming more aware of bilingual AAC and incorporating it into classroom routines to different extents. Additionally, some families engaged more and with enthusiasm in AAC use. Participants observed instances of increased use of bilingual AAC among students, although the extent of home language incorporation varied.

Conclusions:

The findings suggest that participation in a collaborative and reflective PLC can facilitate professional development, improved AAC service delivery, and increased family and student engagement in bilingual AAC. Although the study does not claim direct causation, participants perceived meaningful changes linked to their PLC involvement. Future research should explore the scalability of PLCs in AAC and their long-term impact on service provision and client outcomes.

Barriers to Effective Communication II

Barriers to Effective Communication II

The barriers to effective communication also include cultural barriers, semantic barriers, gender barriers, and time constraints.
Cultural barriers:
Differences in values, beliefs, religion, knowledge, and tradition can significantly impact communication. Awareness of nonverbal cues is critical, especially when conversing with a patient from a different culture. What appears appropriate in one culture may be inappropriate in another.
Semantic barriers:
As a result of their tendency to use...

Community Based Intervention

Community Based Intervention

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

Learning Disabilities

Learning Disabilities

Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

Language and Cognition

Language and Cognition

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Barriers to Effective Communication I

Barriers to Effective Communication I

A communication barrier is any distortion or interruption during a conversation, resulting in miscommunication of the message. A good communicator should know these barriers and continuously check for the listener's understanding by obtaining feedback.
Communication barriers include the following:
Physiological barriers: They are limitations caused by a person's health condition or disability, such as hearing loss, poor eyesight, illness, or unconsciousness. An example to overcome this...

Language Development

Language Development

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...
