AbstractMatrix determinant with the order 2 x 2 and 3 x 3 can be determined by  certainly formula (Sarrus method).  Nevertheless, that method can’t be used and applied to solve the biggest case such as  matrix with order up on it. The Gauss eliminations method  is used  to finish  the matrix determinant with the order 4 x 4 and 5 x 5 by using MATLAB. The calculation results show that the new matrix is produced by row operation elementary like that addition and subtraction between the row have the same  determinant. The resulting  new matrix determinant from the operation of  the exchange between the rows of the matrix has the distinction of beginning so needs to be multiplied by -1. The number of -1 timer involved depending on the multiplicity of exchanges between the line that performed well in the initial matrix or matrix of operating results given. Keywords : Model of solutions, Determinants, Matrix, MATLAB AbstrakMenentukan determinan  matriks berordo 2 x 2 dan 3 x 3 dapat menggunakan rumus yang telah ditentukan (metode Sarrus). Walaupun demikian, metode tersebut tidak dapat digunakan dan diterapkan untuk memecahkan kasus yang lebih besar misalnya matriks yang berordo di atasnya.  Metode eliminasi Gauss digunakan untuk menyelesaikan determinan matriks berordo 4 x 4 dan 5 x 5 dengan menggunakan MATLAB. Hasil perhitungan menunjukkan bahwa matriks baru yang dihasilkan dari operasi baris elementer seperti penjumlahan dan pengurangan antar baris memiliki determinan sama. Determinan matriks baru yang dihasilkan dari operasi pertukaran antar baris memiliki perbedaan dari matriks awal sehingga perlu dikalikan oleh -1. Banyaknya pengali -1 yang dilibatkan bergantung dari banyaknya pertukaran antar baris yang dilakukan baik pada matriks awal maupun matriks baru dari hasil operasi yang diberikan.Kata kunci :  Model Penyelesaian, Determinan, Matriks, MATLAB

Published: October 2018

This study aims at assessing changes in the surface water quality in Dong Nai province (2010- 2014). In addtion, the pollutant loads of wastewater sources were calculated till 2020–2030 with 03 wastewater treatment scenarios serving for the local environmental management. The water quality index (WQI) showed the surface water quality of Dong Nai Province to be gradually improved during the dry season but significantly declined in the rainy season in the last 5 years due to high concentrations of suspended solids (SS), Fe and microorganism - especially in the 3rd segment of Dong Nai river through Bien Hoa City. This current status certainly relates to pollutant loads from waste water sources in the province. Pollutant loads of domestic and industrial wastewater in Bien Hoa city are the highest (40 % per source), livestock activities in Xuan Loc district account for 20 %; aquaculture activities in Nhon Trach district contribute more than 75 % of the corresponding total loads, etc. in which loads of BOD5, COD and SS are significant, about 581,570 tons, 1,035,403 tons and 639,153 tons per year, respectively, and tend to increase in the future, requiring appropriate solutions.

Published: October 2018

The spectral evolution and spectral lag behavior of 92 bright pulses from 84 gamma-ray bursts observed by the Fermi Gamma-ray Burst Monitor (GBM) telescope are studied. These pulses can be classified into hard-to-soft pulses (H2S; 64/92), H2S-dominated-tracking pulses (21/92), and other tracking pulses (7/92). We focus on the relationship between spectral evolution and spectral lags of H2S and H2S-dominated-tracking pulses. The main trend of spectral evolution (lag behavior) is estimated with

(

), where E

p
is the peak photon energy in the radiation spectrum, t + t
0 is the observer time relative to the beginning of pulse −t
0, and

is the spectral lag of photons with energy E with respect to the energy band 8–25 keV. For H2S and H2S-dominated-tracking pulses, a weak correlation between

and k

E
is found, where W is the pulse width. We also study the spectral lag behavior with peak time

of pulses for 30 well-shaped pulses and estimate the main trend of the spectral lag behavior with

. It is found that

is correlated with k

E
. We perform simulations under a phenomenological model of spectral evolution, and find that these correlations are reproduced. We then conclude that spectral lags are closely related to spectral evolution within the pulse. The most natural explanation of these observations is that the emission is from the electrons in the same fluid unit at an emission site moving away from the central engine, as expected in the models invoking magnetic dissipation in a moderately high-σ outflow.
Surface Radioactivity or Interactions? Multiple Origins of Early-excess Type Ia Supernovae and Associated Subclasses
Authors: Jiang Ji-an , Doi Mamoru , Maeda Keiichi , Shigeyama Toshikazu
Published: October 2018

Early-phase Type Ia supernovae (SNe Ia), especially those with luminosity enhancement within the first few days of explosions (“early-excess SNe Ia”), play an irreplaceable role in addressing the long-standing progenitor and explosion issue of SNe Ia. In this paper, we systematically investigate 11 early-excess SNe Ia from subluminous to luminous subclasses. Eight of them are selected from 23 SNe Ia with extremely early-phase optical light curves (“golden” early-phase SNe Ia), and three of them are selected from 40 SNe Ia (including 14 golden samples) with early-phase UV/NUV light curves. We found that previously discovered early-excess SNe Ia show a clear preference for specific SN Ia subclasses. In particular, the early-excess feature shown in all six luminous (91T- and 99aa-like) SNe Ia is in conflict with the viewing angle dependence predicted by the companion-ejecta interaction scenario. Instead, such a high early-excess fraction is likely related to the explosion physics of luminous SNe Ia; i.e., a more efficient detonation happening in the progenitor of luminous SNe Ia may consequently account for the early-excess feature powered by the radiation from a 56Ni-abundant outer layer. The diversity of early-excess features shown in different SN Ia subclasses suggests multiple origins of the discovered early-excess SNe Ia, challenging their applicability as a robust progenitor indicator. Further understanding of the early-excess diversity relies not only on multiband photometry and prompt-response spectroscopy of individual early-excess SNe Ia but also on investigations of the general early-phase light-curve behavior of each SN Ia subclass, which can be realized through ongoing/forthcoming transient survey projects in the near future.
Calibration of Differential Light Curves for Physical Analysis of Starspots
Authors: Basri Gibor
Published: October 2018

This paper presents detailed consideration of methodologies to calibrate differential light curves for accurate physical starspot modeling. We use the Sun and starspot models as a testbed to highlight some factors in this calibration that that have not yet been treated with care. One unambiguously successful procedure for converting a differential light curve into a light deficit curve appears difficult to implement, but methodologies are presented that work in many cases. The years-long time coverage of Kepler provides a strong advantage, but unresolved issues concerning the competing and sometimes similar effects of surface differential rotation versus spot number and size evolution can prevent the confident recovery of correct spot covering fractions in certain cases. We also consider whether faculae are detected by Kepler and/or must be accounted for. We conclude their effects are such that absolute photometry is not required for spot deficit calibrations. To elucidate their signature, we re-examine correlations between absolute brightness, differential variability, and apparent spot coverage for hundreds of Kepler stars with absolute calibrations from Montet et al. The results are similar to theirs, but we draw somewhat different conclusions. Most of the stars in this active solar-type sample are spot-dominated as expected. Partly because of a dearth of longer period stars, the evidence for facular dominance in this sample is both sparse and relatively weak. The facular population exhibits a puzzling lack of dependence on rotation period, which raises questions about the apparent detection of a “facular” signal at short periods.

The Case for Smart Specialization Strategies (RIS3) as an Instrument for Place-Based Policies
Authors: Ferreira Filipe , Seixas Paulo Castro
Published: October 2018

Place-based policies are considered the new regional policy paradigm, replacing an existing concept of regional development pillars and redistributive logics. At EU policy-making level, the territorial dimension of the programming cycle for 2014-20 requires place-based policies to the formulation and implementation of a new set of instruments as the smart specialization strategies (RIS3). Based on dynamic competitive advantages anchored on territorial idiosyncrasies, RIS3 are as well an ex-ante condition of access to the structural funds at both a national and regional level. RIS3 are thus seen by us as a benchmark instrument for the place-based theory. An analysis of the scientific literature and official documents of the EU and its member states supported a correlation matrix that cross-referenced the characteristics of the RIS3 with those of the regional policy paradigms. Results reveal that RIS3 are hybrid policy instruments partly place-based but still with characteristics that bring them closer to the polarized and redistributive paradigm.

Authors: Dettenhofer Markus , Doussineau Mathieu , Arregui-Pabollet Eskarne
Published: October 2018

The chapter examines the multi-dimensional university governance topic, looking into five governance dimensions of universities and the differences across EU member states. It analyzes how the differences in university governance dimensions influence in their role in their regional research and innovation systems, and specifically in the smart specialization strategies (S3) implementation. The S3 is a new policy that has introduced novelties in regional development policy, requiring the mobilization of quadruple helix actors in setting the regional priorities for innovative potential. The involvement of universities in the formulation of these strategies is of high importance; however, it poses a number of challenges, particularly in regions with incipient regional innovation systems with low institutional capacity and leadership to coordinate the different actors' capacities. The chapter sheds light for policymakers and university managers on the most relevant university governance dimensions that can influence on how they engage with their regional research and innovation system.

Authors: Marinelli Elisabetta , Mironov Cosmina
Published: October 2018

The chapter analyzes the links between the higher education system and the design and implementation of smart specialization strategies in north-east Romania, with the aim of providing actionable steps for policymakers, higher education institutions (HEIs), and other stakeholders. This case study allows reflecting on the potential of smart specialization in a region recognized as a higher-education hub in Romania and characterized by a very proactive regional development agency (RDA), but in which universities display limited engagement with the territory and where public administration is highly centralized. The findings identify actions that HEIs and the RDA can undertake to enhance universities' roles within RIS3. These revolve around (1) improving collaborations among HEIs within the region; (2) accessing international collaboration networks for research, teaching, and innovation; and (3) finding avenues of interaction with local actors.
Digital Image Enhancement Techniques for Dental Radiographs
Authors: Priya E.
Published: October 2018

Dental radiographs suffer frequently from issues such as low contrast and non-uniform illumination. The first step, indeed a significant step, is to enhance these digital images to prepare them for successful post-processing. This pre-processing stage assists to increase the contrast between the foreground that is the teeth and bone from the background regions. In this chapter, image enhancement methods based on spatial, frequency, and spatial-frequency are implemented. The dental radiographs used are available in the public database. The performance of the enhancement methods is validated using qualitative and quantitative measures. It is observed from the results that the enhancement method aids in improving dental features such as crowns, fillings, and bridges. This enables human identification and diagnostic purpose in the way it is possible to identify a variety of diseases. It also prevents the need for a remake, saving the patient from an additional treatment.

As globalization continues to be a reality around the world, the rules and context of business activity have been affected. Globalization increases the complexity of businesses and drives managers to be globally oriented. With globalization, people from various cultural backgrounds get together virtually and interact. National boundaries of countries are becoming less relevant. More significantly, the impact of technology and particularly information and communication technology (ITC), is the other characteristic aspect of the 21st century. ITC is essential in today's business and modern globalization as business partners are constantly in communication around the globe. This chapter discusses the effect of globalization and the global business environment as it is shaped by various economic and politic-economic blocks around the world.
Integrating Multiculturalism in the Design and Implementation of Work-Life Balance Strategies
Authors: Abe Ethel Ndidiamaka , Abe Isaac Idowu
Published: October 2018

Globalization has affected the outlook of contemporary workforce through migration by introducing multiculturalism. Customary work-life balance strategies (WLBS) are not adequate in addressing work-family challenges faced by employees in the 21st century. This chapter furthers literature on the integration of multiculturalism in the design and implementation of WLBS to address the needs of employees in multinational corporations. A concise review of previous studies on multiculturalism and work-life balance was carried out. This chapter submits that WLBS do not address the issues of multiculturalism in managing each group challenges in accordance with their cultural backgrounds; therefore, most of these WLBS are not achieving the objectives for which they were adopted. The review of literature also noted the existence of traditional WLBS and emerging non-traditional interventions. The managerial implication of this chapter hinges on adoption of pragmatic strategies to address multiculturalism in the design and implementation of WLBS.

Authors: Genty Kabiru Ishola
Published: October 2018

Leadership in this 21st century need to shift their tents to cover major areas of technological revolution, especially interpersonal relationships among the global leaders due to globalization challenges. For this purpose, the chapter attempts to interrogate the concept of interpersonal relationship and its correlation with global leadership mindset. A literature review was conducted to establish the link between global leadership mindset on the interpersonal relationship, particularly cultural differences. Discourse content analysis was carried out to explain the collected information. It was established that job-related interactions and social interactions within the work enhance cordial relationships among peers, subordinates, and superiors. However, today's global leaders have been shying away from this responsibility. The chapter concludes that strategic partnership is required by the global leaders in the area of relational competencies such as social interaction, supportive networking, and avoidance of racial discrimination in order to achieve global performance.

Published: October 2018

Sustainability is concerned with the most efficient use of resources where the residues play an essential role. Trends in concrete technology include natural or artificial additions and additives in order to reduce the consumption of cement. The characterization of the wastes is of great importance with respect to the amount that must be incorporated into the matrices of construction materials both for its economic and engineering impacts (strength and durability). The authors study the impact in strength, durability, and sustainability of the use of finely ground waste of ferroalloys in concrete. The behavior of durability of sustainable concrete also is evaluated. The proportioning between traditional materials and these additions involves preliminary tests on pastes and mortars. Also, they study the impact of the use of different plastic wastes (polyethylene) in different percentages. They evaluated consistency, compressive strength, suction capability, and leaching.
Energetic Forms of Matter
Authors: Ida Aletheia
Published: October 2018

One of the challenges that architects and designers are confronted with in contemporary contexts is the need to address an ethical responsibility towards the health of the environment through understanding the energetic processes embedded in materials and their compositions. A scientific explanation of material fundamentals, including chemistry, physical structure, and embodied energy, provides the greatest insight to material property performance values and relative environmental impacts. This information aids architects in making informed decisions about building materials in the design process. This chapter addresses the book topic of reusable and sustainable building materials through the position that all matter is a form of energy, just as living systems are the transmutation of matter and energy. The seven major material groups, which include natural materials, non-technical ceramics, technical ceramics, metals, polymers, foams and elastomers, and composites, are presented with examples and applications discussed.
The Development of Technology Integration in a Graduate Course for Practicing Teachers
Authors: Smits Anneke , Voogt Joke , van Velze Lieke
Published: October 2018

This chapter describes the design and outcomes of a graduate course for practicing teachers that aims to develop the quality of technology integration in their educational contexts. The course is rooted in a set of concepts and theories and in three pedagogical principles for enhancing teachers' technology integration. The outcomes of the course were measured by using a mixed methods design. After the course, all students showed satisfactory TPACK scores and most students (83%) produced lessons that showed a good quality of technology integration, and 75% of the lessons showed a rich array of technological affordances. Neither the quality of the technology integration as shown in their lesson design and enactment nor the number of different technological affordances students showed in their (enacted) lesson design were related to students' TPACK scores after the course. This unexpected finding is discussed. Students reported a development from unconscious technology integration to conscious technology integration.

Authors: Thomas Amanda , Trainin Guy
Published: October 2018

This case study outlines the components and outcomes of a program-wide approach to transforming elementary pre-service teachers' technological pedagogical content knowledge (TPACK). The approach emphasized the creation of laboratories of practice in which pre-service teachers learned about and enacted technology for teaching and learning. Pre-service teachers developed TPACK through carefully designed and scaffolded learning experiences in technology and content methods coursework, internship experiences, and student teaching. The case offers descriptions and outcomes within a mathematics methods course and across eleven cohorts of student teachers. TPACK survey results at the beginning and end of one course of the program, and measures of TPACK-efficacy and frequency of technology integration at the end of the program indicate that the programmatic approach led to TPACK growth among pre-service teachers.
Ubiquitous Bodies
Authors: Cipolletta Giorgio
Published: October 2018

While the digital era has provided us with an incredible amount of accessibility, availability, and speedy tools, it has also made us lose that sense of critical awareness that was once considered a rare and precious gift. The marking feature of the present is ubiquity, as in the loss of spatial and temporal coordinates and the gain of a presence-absence that new technologies allow us to live – both positively and negatively. The body is the core of this electronic, virtual, and increased involvement. In this phase we're living in, the author suggests we introduce the neologism “metrobody” to identify this new hybrid condition undertaken by the body. This expression allows the author to reconfigure and hypothesize a different level and a different meaning of corporeality.

Published: October 2018

Teacher self-efficacy is an important motivational construct that informs actions associated with teaching. Teacher self-efficacy develops during teacher education. Highly effective teacher education is able to support and enhance self-efficacy. Variation however can occur for a number of reasons. In the case of digital technology and the arts, teacher self-efficacy informs perceived levels of competence in teaching students. This chapter reports on the current levels of teacher self-efficacy of pre-service teachers at three Australian universities. Dance, drama, music, media, visual arts and digital technology were explored. Findings highlight that the different cohorts had different levels of perceived competence. Such findings are important for teacher education and also the professional development of teachers for arts and digital technology education.

Authors: Cuthrell Kristen C. , Lys Diana B. , Fogarty Elizabeth A. , Dobson Ellen E.
Published: October 2018

This chapter will share a model for teacher preparation programs to consider when attempting program improvement through the use of edTPA data. This model, regardless of the edTPA context, mandated or voluntary, provides a frame in which teacher education programs can begin using edTPA data for program improvement and can advance their data use towards transformative, institutional improvements. This additive model takes time, commitment, and vision in order to systematically create programmatic improvements. Performance assessment data provides the structure and information needed for units and programs to make these purposeful changes. The increasingly explicit culture of assessment in teacher education, in conjunction with the promise of valid and reliable performance assessments, invites teacher education programs to engage in third spaces with renewed focus.

It is the unavoidable and it is not going away. The gravity of technology has firmly planted itself in our daily existence and yes, this includes teacher education. As technology has because our normative environment in daily life it has also become normative in educator preparation; our new oxygen. This commonplace element is hailed as a tool of equity for learners, preschool through college. Our current populations of learners are digital natives, but many educational leaders are digital tourists. As we look to challenge the traditional notions of distance learning, program offerings, and educator preparation models we must rapidly embrace the persona of the digital native to increase relationships with those we prepare as teachers while at the same time valuing and increasing diversity and voice. This chapter seeks to examine how a teacher educator engages preservice teachers in the world of diversity using technology.

Common Scenario for an Efficient Use of Online Learning
Authors: Nuninger Walter
Published: October 2018

Training efficiency required for Higher Education (quality, accessibility, bigger groups with heterogeneous prior experience, funding, competition…) encourages providers to find new ways to facilitate access to knowledge and enhance skills. In this scope, the use of digital pedagogical devices has increased with innovative solutions; the ones based on an LMS to support a blended course or MOOCS design for self-education. This evolution has impacted teaching practices, learning and organizations leading to a new paradigm for trainers and a new business model to be found for online and distance learning. The innovation mostly relies on the use of learner-centered digital learning solutions in a comprehensive way for the commitment of more active and independent learners and their skills recognition. Based on a 3-year experiment (hybridized course for CVT) and continuous improvement in the WIL, a common scenario is proposed to address the issue for distance training.

Authors: Catelli Linda A. , Carlino Joan , Petraglia GinaMarie , Godek Patricia , Jackson Valerie
Published: October 2018

Race to the Top (RttT) reforms in States around the nation have initiated changes in the way teachers are evaluated and in the way new teachers are certified. The focus of this chapter is on sets of video-based action research studies aimed at analyzing and assessing classroom teaching performances and evaluating program effectiveness in a Professional Development School (PDS) partnership setting. The studies were part of a larger longitudinal research project begun in 1998. Authors present selected sets of studies as exemplars of a model research approach for continually changing and improving classroom teaching and the PDS's integrative pre-and inservice teacher education program. Readers are provided with the research and inquiry questions of the studies, key findings, and how findings were used to provide evidence of program effectiveness.
A New Paradigm for Learners and Teachers Thanks to Situational Pedagogical Games
Authors: Nuninger Walter , Châtelet Jean-Marie
Published: October 2018

Part of sustainable outcomes in Higher Education relies on the design of trainings able to help learners to develop transversal skills. Beyond such challenges, the aim is to obtain widespread involvement and to take advantage of interaction and dialogue in order to facilitate deeper learning and strengthen autonomy and decision-making based on specific context. An evolving pedagogical game, conducted over fifteen years in Master's degrees with inter-cultural groups, is presented; guiding learners towards skills in quality management. It has inspired a set of pedagogical mini-games (lasting less than two hours) as a solution to face the evolution of trainees' expectations and the reduction of time; part of hybridized courses, the aim is to incent involvement and learning with focus on knowledge. Results and comparison bring out the non-variable parts in order to make the best of such devices; worthwhile adaptation to increase problem-solving ability and future efficiency in the workplace.
Expanding Opportunities in Teacher Education
Authors: Mitchell Donna Mathewson
Published: October 2018

Initial teacher education has a critical role in preparing future teachers. In an era of increasing distance education, an additional challenge is to effectively prepare pre-service teachers who connect with higher education in an online environment. The diversity of the higher education student cohort studying by distance is significant and can easily be rendered invisible through the ‘facelessness' of digital technology. In addressing this challenge, this chapter outlines an innovative program undertaken in two secondary visual arts curriculum subjects delivered in distance mode in a graduate-entry teaching course. The innovation models a practice-based partnership involving higher education and community and culminates in a professional student exhibition. Outcomes include: positive student experience; high levels of achievement; increased civic consciousness and involvement; meaningful integration of cross-curriculum perspectives; and sustained focus on teaching practice. The program provides an example of an integrated use of technology to enhance university teaching and learning with the aim of informing future K-12 educational possibilities.
Practicum-Based Approach to Bridge Between Information-Systems Industry Expectations and Graduates Qualifications
Authors: Lavy Ilana
Published: October 2018

In this study, a practicum-based approach to bridge the gap between industry expectations and Information Systems graduates skills is presented and discussed. Students participate in the practicum project during their last study year, and take part in various professional activities in the industry in accordance with their professional aspirations and their desired specialty. Semi-structured questionnaires and interviews with students who participated in the project in the last four years were conducted in order to reveal the students' perceived contributions of the project. The students experienced real workplace environments, acquired extended knowledge and skills, built social infrastructure to assist them with future job seeking, and above all gained real world experience that help them to build their professional image, and gain confidence in their traits and abilities. In addition, the practicum-based approach was compared with other common approaches used to bridge the gap, and its relative advantages and disadvantages were discussed.

This chapter explores a number of issues for consideration when adopting and implementing edTPA as a summative performance-based assessment of preservice teacher candidate tasks. This chapter aims to offer guidance and support for programs in the beginning stages of implementation of edTPA. Each of the considerations includes a vignette from personal experiences at a regional comprehensive university in the southeast. Issues discussed include timeline for implementation, buy-in, decision-making processes, professional development and training, mapping, and next steps. The vignettes detail particular issues or concerns and include faculty, staff, and/or teacher candidates. Data used to develop the vignettes was collected via interviews, surveys, and reflections.
Prospective EFL Teachers' Perceptions of Using CALL in the Classroom
Authors: Rakicioglu-Soylemez Anil , Akayoglu Sedat
Published: October 2018

The study focuses on prospective English as a foreign language (EFL) teachers' perspectives on the use of Computer Assisted Language Learning (CALL) resources in teaching English as a foreign language context. In addition to examining prospective teachers' perceptions, the similarities and differences in their perceptions and factors affecting their beliefs about using CALL resources will be addressed. The study aimed to identify the prospective EFL teachers' perceptions of their existing skills to integrate CALL into their future professional practices. The perceived factors that will facilitate and inhibit their future teaching practices by using CALL resources and their expectations from the teacher education program in terms of providing the necessary training to use CALL resources in their teaching practices were examined. The perceived benefits and challenges of using CALL in EFL teaching contexts will be addressed from the participants' perspectives. Finally, the study provides implications for further research in addition to recommendations for EFL teacher education programs.
Blended Learning in Teacher Education
Authors: Kim Jackie HeeYoung , Baylen Danilo M. , Leh Amy , Lin Lijia
Published: October 2018

This chapter acknowledges that there is sparse literature to consult about the pedagogical and empirical foundations of blended learning in teacher preparation programs because this field is in its infancy. This chapter will first define blended learning, identify the challenges in teacher preparation programs and indicate how blended-learning approaches will assist teacher educators to meet long-standing and newly emerged challenges, and help future teachers to be reflective practitioners, better problem-solvers, and critical thinkers. This chapter also will discuss pedagogical values of blended learning and factors affecting blended learning course designs, and then showcase best practices using blended learning in order to show the effectiveness of blended learning approaches in teacher education. Lastly, this chapter will discuss considerations when blending teacher education courses.
Case Study Analysis of a Team/Collaborative Model With Specific Learning Disabled Students
Authors: Epler Pam L. , Ross Rorie
Published: October 2018

This chapter focuses on Specific Learning Disabilities (SLDs), which is the most common type of designated disability among school-aged students in the United States. SLD is a disability that can have devastating effects on a student's learning ability, as in the most severe cases the SLD student may remember little, if anything, about what he or she has learned; may have difficulties focusing on even one thing; may not be able to read above an elementary level; and may live in isolation due to poor social and motivational skills. This chapter discusses the service delivery models for students who have SLD and provides two case studies of models that can be successful if implemented properly. Finally, the chapter presents intervention strategies to assist the general education teacher when working with students with SLD.
