Learning is the process of restructuring mental schemas through adaptation to new experiences. Instructional materials help form a suitable and individualized educational environment for students with hearing loss while facilitating lexical development and comprehension of academic content. This case study aims to demonstrate the contribution of visual and audiovisual materials to the efficiency of the Social Studies Course for 4th-grade students with hearing loss. Findings of the study have been collected through video recordings of the lessons, validity meetings, the research log, realia, photographs/images, graphic organizers, and educational videos/documentaries. Data analysis demonstrates that the use of visual and audiovisual materials contributes substantially to students’ (a) comprehension of the questions and explanations, (b) participation in and drawing conclusions from classroom discussions, and (c) understanding of new vocabulary and concepts. Based on the results, it can be argued that the use of visual and auditory materials presented so as to cater to the individual needs of the students, together with various educational strategies, provides significant advantages in the acquisition of academic knowledge by students with hearing loss.

Background: Mastoidectomy is the mainstay of COM treatment . Usage of the micro motor drill has an effect on the contralateral ear due to the noise induced by the drill and the sound-conducting characteristic of the intact skull. Aims And Objectives: 1. To identify the drill induced hearing loss in the contralateral ear, by transient evoked otoacoustic emissions following mastoidectomy. 2. To identify the relation between the type of burr tip used and the amount of hearing loss. Methodology: This study consisted of 63 patients that underwent mastoidectomy. A pre-operative PTA and TEOAE was done. PTA was repeated on POD-1 and POD-7. TEOAE was done on POD-1,3 and 7. Intraoperatively, the type of burr tip used and the individual drilling time for each type of drill bit was recorded. Results: 37 patients developed transient SNHL by POD-3. All patients recovered by POD-30. Higher frequencies of 3000 Hz and 4000 Hz were commonly affected. No change was detected on PTA. Conclusion: The drill is not only a source of noise but is also a strong vibration generator. These strong oscillations are transmitted into the cochlea. Thus surgeons should select appropriate burrs and drills to minimize the temporal bone vibrations.

The suprathreshold acoustic reflex responses of forty two ears affected by sensorineural hearing loss of cochlear origin and fifty-eight ears demonstrating normal hearing, were recorded by means of an electro-acoustic impedance meter and attached X-Y recorder. The recordings were done in ascending and descending fashion,  at successively increasing and decreasing 5dB intensity levels from 90-120-90 dB HL respectively, for the individual pure-tone frequencies of 500, 1 000, 2 000 and 4 000 Hz. The contralateral mode of measurement was employed. Analysis of  these recordings indicated that the acoustic reflex  responses could be differentiated into five  characteristic patterns of  growth, which could be depicted upon a continuum of peaked, peaked-rounded, rounded, rounded-flat,  and flat  shapes. The peaked and peaked-rounded patterns were found  to predominate at all four pure-tone frequencies  in the normal ears, while the rounded-fiat  and flat  patterns were found  to predominate only at the higher pure-tone frequencies of 2 000 and 4 000 Hz in the ears affected  by sensorineural hearing loss. This latter relationship was also able to be applied to two disorders of  the loudness functio— loudness recruitment and hyperacusis. It was concluded that the flattened  acoustic reflex  patterns at the higher pure-tone frequencies  constituted a potential diagnostic cue related to the differential  diagnosis of sensorineural hearing loss, and to disorders of  the loudness function.

AbstractAn increasing volume of data suggests that changes in cellular metabolism have a major impact on the health of tissues and organs, including in the auditory system where metabolic alterations are implicated in both age-related and noise-induced hearing loss. However, the difficulty of access and the complex cyto-architecture of the organ of Corti has made interrogating the individual metabolic states of the diverse cell types present a major challenge. Multiphoton fluorescence lifetime imaging microscopy (FLIM) allows label-free measurements of the biochemical status of the intrinsically fluorescent metabolic cofactors NADH and NADPH with subcellular spatial resolution. However, the interpretation of NAD(P)H FLIM measurements in terms of the metabolic state of the sample are not completely understood. We have used this technique to explore changes in metabolism associated with hearing onset and with acquired (age-related and noise-induced) hearing loss. We show that these conditions are associated with altered NAD(P)H fluorescence lifetimes, use a simple cell model to confirm an inverse relationship between τbound and oxidative stress, and propose such changes as a potential index of oxidative stress applicable to all mammalian cell types.

Hearing impairment is defined as hearing loss that leads to difficulties in hearing, or deafness, and affects an estimated 360 million people worldwide. Consequences of hearing impairment include difficulties in communication, restricting social participation, and leading to feelings of isolation. Hearing impairment cannot be cured, but its consequences can be reduced with self-management whereby the individual adopts, refines, and maintains health behaviors, supported through the provision and availability of suitable interventions. The barriers to self-management are many and should be explored to inform decision-making between the clinician and the individual with hearing impairment. The clinician can then facilitate self-management that is informed, realistic, and fully reflects the preferences and values of the individual.

Most teachers have experienced various forms of prejudice expressed in the classroom. When one hears attitudes or opinions that go against school and society’s values, it is not always easy to know how to respond appropriately and wisely.Educators have a social responsibility both towards the individual and the community. Individuals are the learning subjects, but the context for learning is group-based. Teachers’ social responsibility entails both individuals that have expressed prejudice against a particular group, and those who identify themselves with this particular group. In addition, educators have responsibility for the group based learning arena, which all the individuals belong to. Beyond this, schools are expected to contribute to a democratic society. Preventing prejudice expressed in the class room will not only ensure a safer environment for the pupils, it will also contribute to society as a whole by promoting democratic values. In other words, there are several reasons why schools should work to prevent prejudice.Many have antipathies or prejudices against groups of people. However, but some groups are more often faced with prejudice than others. A prerequisite for the development of prejudice is the formation of categories. People are able to suppress their prejudices. Prejudice is not created in a vacuum; they are social stances that must be understood in the context of the specific human environment. Studies show that if a person has prejudices against Jews, for example, the person tends to be more disposed to have prejudices against other groups as well, such as for example gays, , Muslims and immigrants. This disposition is called "group focused enmity."When a child is between eight and twelve years, the child starts to check and correct its perception of the world. Before it reaches this stage, the child’s comments about out-groups mainly stems from other people’s instructions. Studies from the USA have shown that negativity towards people with a different skin color decreases from around the age of 10 compared to when the child was younger.An individual's attitudes are formed on the basis of that person's overall experience. Although formed individually, experience often take place in social interaction with other individuals. In social settings, people find their significant other, that is, an individual or individuals they may mirror and adjust to. Such individuals may include parents, siblings, friends and teachers. The school is therefore a very important arena for promoting positive attitudes.Albert Einstein allegedly claimed that "It is harder to crack a prejudice than an atom." But even if we take hold of prejudices and actively seek to fight them, it will require time and energy. The process of changing a person’s attitude is significantly longer than the process of developing a person’s academic knowledge and skill.It is often said that "prejudice must be fought with knowledge." Prejudice consists of both beliefs and attitudes. It is important that educators have access to constructive meeting arenas, read books, play games and watch movies that can make room for empathy. It is essential to find learning resources, initiatives and approaches that promote values such as empathy and community, and then creating positive experiences for the pupils.

Teachers, trainers, and educational designers often face the problem of choosing the most suitable media for achieving their educational purposes. To solve this problem, they need to take into account both the variables at play in the educational setting and the characteristics and potentialities of the media available. This chapter discusses the criteria for media choice, with particular attention to the point of view of the individual teacher who makes decisions on the basis of the educational strategies he or she deems most appropriate and, given that schools usually have limited resources, must favor techniques for material retrieval and reuse rather than new development.

Using the Hearing Handicap Inventory for Adults (HHIA), we assessed self-perceived hearing handicap in a sample of 63 patients having either unilaterally normal hearing or a mild hearing loss (pure tone average ≤40 dB hearing level). Large intersubject variability in responses to the HHIA confirmed observations that reactions to minimal hearing impairment vary greatly among patients. The individual differences in responses highlight the importance of quantifying the perceived communication and psychosocial handicap, which cannot be determined from the audiogram alone. An item examination of responses to the HHIA revealed a number of emotional and social-situational problems encountered by patients with minimal hearing loss.

Hong Kong has adopted a dual-track system of the education for students with special educational needs (SEN). The system provides a diverse school education to cater to the individual needs of students. In principle, students with SEN are encouraged to receive education in ordinary schools as far as possible. Students with severe SEN or multiple disabilities, however, can be referred to special schools for intensive support services upon the recommendation of specialists and with parents’ consent. Before the launch of the pilot scheme of integrated education in 1998, students with SEN were mostly placed in special schools. The change from a mono-track system to a dual-track system caused concerns for teachers in ordinary schools. This is because integrated education is more than placing students with SEN in ordinary classrooms. It involves a total change in the way schools and teachers operate. Teachers require the skills and background knowledge to support a diverse range of students in the classroom through ordinary classroom practices, and the ability to meet the needs of every student as an individual. In Hong Kong, most teachers have particular concerns about the short duration of training in professional development, the difficulties in the design of the curriculum and assessment differentiation under the three-tier support system, the practice of collaboration among different teaching teams, and the change of administrators’ perceptions on the education of students with SEN. The central authority and the school community should work collaboratively to deal with these pressing difficulties.

Sensorineural hearing loss is one of the most common disabilities in humans. It is estimated that about 278 million people worldwide have slight to extreme hearing loss in both ears, which results in an economic loss for the country and personal loss for the individual. It is thus critical to have a deeper understanding of the causes for hearing loss to better manage and treat the affected individuals. The mouse serves as an excellent model to study and recapitulate some of these phenotypes, identify new genes which cause deafness, and to study their roles in vivo and in detail. Mutant mice have been instrumental in elucidating the function and mechanisms of the inner ear. The development and morphogenesis of the inner ear from an ectodermal layer into distinct auditory and vestibular components depends on well-coordinated gene expression and well-orchestrated signaling cascades within the otic vesicle and interactions with surrounding layers of tissues. Any disruption in these pathways can lead to hearing impairment. This review takes a look at some of the genes and their corresponding mice mutants that have shed light on the mechanism governing hearing impairment (HI) in humans.

This chapter explores the acquisition of spoken language and literacy in children with hearing loss whose auditory access through the use of hearing technology enables them to listen, and it examines the relationships among language, thought, and print that offer explanation of the role of spoken language as the foundation for literacy. It defines reading and writing as thinking processes that make use of symbol systems representative of spoken language and gives attention to the numerous cueing systems and conventions comprising representations of meaning. Drawing from cognitive psychology, linguistics, psycholinguistics, sociolinguistics, literary criticism, and critical traditions developed over time through study of people with typical hearing, this chapter argues that meaning making resides in the individual in the presence of symbols both heard and seen and for maximizing spoken language acquisition in children with hearing loss so as to prepare them for lifelong literacy and language use.
