Seven studies showed a low risk of bias while three studies showed a high risk of bias according to the Jadad scale. The Jadad scale scores the methodological quality of trials based on randomization, blinding, and withdrawals. Both the Jadad scale and Delphi scale were used to assess study quality, where only studies with a Jadad score of 4-5 and a Delphi score of 6-9 were considered high quality.

Brown Myford NCME presentation
This study investigated potential method effects in performance assessments used by two medical specialty certification organizations. Using many-facet Rasch measurement, the study compared candidate proficiency, examiner severity, and case/protocol difficulty across assessment formats. Some differences were found between formats for 12-17% of candidates and 15-27% of examiners, indicating possible method variance. Cases tended to be easier or harder to get high ratings than protocols depending on the organization. The results provide initial evidence of method effects, but limitations prevent definitive conclusions about specific sources. The findings suggest certification organizations should consider steps to mitigate method variance.
Test standardization
Standardized tests are designed and administered consistently to allow for comparison of student performance. Tests are given to a sample group to determine average scores and the spread of scores. This establishes norms that individual students can be compared to. There are two main types of standardized tests - norm-referenced tests which compare students to peers, and criterion-referenced tests which assess knowledge of a defined subject area. Tests go through a process of development that includes trying out drafts, analyzing results, revising weak questions, and further testing to establish reliability and validity.
Psychological Test Construction and its steps
The document discusses test construction and evaluation in student assessment systems. It describes the meaning of psychological tests and their various types. It outlines criteria for good tests, including practical criteria like purposefulness and technical criteria like standardization. The process of test construction is explained, including planning, drafting preliminary and final versions, tryouts involving pre-testing and item analysis to evaluate difficulty and discriminative power. Methods to determine reliability through re-testing and validity through correlation are presented. The document also discusses Bloom's taxonomy of educational objectives and writing objectives in behavioral terms.
Reliability and validity of Research Data
The following PPT is PPT submitted and presented in partial fulfillment of Research Methodology in English Language Teaching Course. under the guidance of Dr. H. Nur Samsu, M.Pd.
Aligning tests to standards
This chapter discusses aligning language tests to standards. It defines standard setting as establishing cut scores on exams to assess learner performance against an absolute standard. Various standard setting methodologies are presented, including test-centered methods like Angoff and Ebel, and examinee-centered methods like contrasting groups. Effective standard setting requires expert judgment, training judges, and evaluating the process and results both internally and externally. While standards can promote harmonization, issues like unintended consequences, lack of context specificity, and forcing consensus must be considered. Ultimately uncertainty remains in standard setting.
Testing in language programs (chapter 8)
The document discusses the reliability of language tests. It defines reliability as the ability of a test to consistently produce the same results under the same conditions. There are different types of reliability: test-retest reliability measures consistency over time; parallel forms reliability uses different but comparable test forms; and internal consistency examines consistency between parts of the same test using methods like split-half reliability and Cronbach's alpha. Reliability can be affected by factors like test length, range of scores, and item similarity. Ensuring high reliability is important so tests accurately measure constructs without measurement error.
New item analysis
Item analysis is a process used to evaluate test questions and assess the quality of a test. It involves both qualitative and quantitative procedures. Quantitatively, it examines the difficulty index, discrimination index, and distractor power of each question. The difficulty index indicates how many students answered correctly, the discrimination index shows if a question distinguishes between high- and low-scoring students, and distractor power evaluates the effectiveness of incorrect answer options. Conducting item analysis helps improve the validity and reliability of assessments by identifying high- and low-quality questions.
Overview of GRADE approach_selected slides for Cochrane Public Health.pptx
This document provides an overview of the GRADE approach for evaluating evidence and developing recommendations. It discusses that GRADE provides a systematic, explicit approach to appraising evidence quality and recommendation strength. Evidence quality can be high, moderate, low, or very low based on study design and risks of bias. Recommendation strength can be strong or weak/conditional based on how desirable versus undesirable effects are balanced based on the evidence and other factors.

Test interpretation and report writing
The document provides guidance on scoring and interpreting results from the NCIP aptitude test. It discusses using norms to interpret scores by comparing them to the mean scores of the norm group. High, moderate, and low ranges are provided for factors like deportment, learning process, and motivation. The document also reviews the different uses of tests and discusses norm-referenced versus criterion-referenced interpretation of scores. It provides an example of how to convert a raw score to a standard score based on the normal distribution curve.
Analysis of item test
The document analyzes the validity, reliability, difficulty, distinguishing characteristics, and response patterns of a 40-item multiple choice test administered to 7th grade students. The analysis found that 3 items were valid, the test had high reliability, difficulty levels varied but most items were easy, characteristics varied from poor to excellent, and most items and distractors were good with room for improvement. In conclusion, most items could be used again but some invalid items need replacing to effectively measure student ability.
Analysis of item test
The document summarizes the analysis of a 40-item multiple choice test administered to 7th grade students. The analysis examined the test's validity, reliability, difficulty, distinguishing characteristics, and response patterns. The summary is:
(1) Validity analysis found 3 valid items (7.5%) and 37 invalid items (92.5%) that should be replaced, as they could not accurately measure ability.
(2) Reliability was high, with 21 items very reliable and the rest highly reliable, allowing consistent ability measurement.
(3) Difficulty varied, with 4 hard, 13 average, and 23 easy items, showing most items were easy for the students.
Instrumentation
This document discusses instrumentation and quantification in research methods. It defines reliability as consistency over time, between parallel tests, and within test items. There are four main methods to estimate reliability: test-retest, parallel forms, split-half, and internal consistency. Interrater reliability measures consistency between raters, while intrarater reliability measures consistency of a single rater over time. The document also discusses criterion-related and construct validity. A key point is that a measure can be reliable without being valid, but cannot be valid without first being reliable.

Bonding between materials can occur through either adhesion or cohesion. Adhesion is chemical bonding between dissimilar materials through the reaction of atoms and molecules at the interface. Examples include denture retention through a thin film of saliva. Cohesion is bonding between similar materials through the same type of bonds, such as bonding two pieces of gold together. For adhesion to occur, the materials must be in intimate contact and the adhesive applied in liquid form to create a thin bonding layer. There are two main mechanisms of adhesion: mechanical adhesion through interlocking of the adhesive in surface irregularities of the adherend, and chemical adhesion involving direct bonding between molecules.

Adhesion is the chemical bonding between dissimilar materials through the reaction of their atoms and molecules, such as the adhesive action of saliva bonding a denture to soft tissue. Cohesion is the bonding between similar materials, like two pieces of gold bonding together through metallic bonds under pressure. For adhesion to take place, the materials being joined must be in intimate contact and the adhesive must be applied in a liquid state to form a thin bonding layer. There are two main mechanisms for adhesion - mechanical adhesion which involves the flow of a liquid adhesive into surface irregularities of the adherend to form a mechanical interlock without an actual chemical bond, and chemical adhesion which forms a

Adhesion occurs through chemical bonding between dissimilar materials at the atomic and molecular level, such as the bonding between a denture base and soft tissue through a thin film of saliva. Cohesion is bonding between similar materials through the same type of bonds, such as bonding two pieces of pure gold together under pressure via metallic bonds. For adhesion to occur, the materials being joined must be in intimate contact and the adhesive must be applied in a liquid state to form a thin bonding layer. There are two main types of adhesion: mechanical adhesion through mechanical interlocking of an adhesive that flows into surface irregularities of the adherend; and chemical adhesion involving direct chemical bonding between the adhesive and adherend at the molecular level.
dental implant.pptx
Titanium and its alloys have several desirable properties for use in dental implants, including high strength, light density, corrosion resistance, and a modulus of elasticity close to bone. Specific alloys like Ti-6Al-4V can have tensile strengths over 500 MPa, densities around 4.5 g/cc, and melting temperatures between 1300-1500°C. The surface of titanium implants can be roughened through processes like plasma spraying, grit blasting, acid etching, or anodization to encourage osseointegration with bone.
ceramics.pptx
Dental ceramics are compounds formed from metallic and non-metallic elements whose desirable properties are achieved through high-temperature firing. They include oxides, nitrides, and silicates used in dental materials like gypsum, cements, composite fillings, and porcelain. Ceramics range from purely ionic to covalent or a combination of bonding, have high melting temperatures and stability but are brittle with low fracture toughness and act as electrical and heat insulators due to their lack of free electrons. Silica-based ceramics can form glass through vitrification or crystals through devitrification.
Microsoft PowerPoint - German-Smart Materials in Dentistry [Read-On.pdf
The document discusses smart materials for dentistry and their potential applications. It defines smart materials as those that can interact with their environment to provide beneficial outcomes. Examples mentioned include chromogenic systems, piezoelectric materials, and shape memory alloys and polymers. The document explores how certain dental materials like glass ionomer cements (GICs) and resin-modified GICs (RMGICs) exhibit smart behaviors through water absorption, thermal expansion and contraction, and sustained fluoride release and recharging. Controlling porosity and biofilm interactions are discussed as ways to optimize these smart behaviors. The concept of a "smart cycle" is introduced where biofilms concentrate and store fluoride, then acid conditions trigger its release in a beneficial

Ceramics are brittle with higher compressive than tensile strength due to small flaws and cracks. They are hard with low fracture toughness. Vitrification is the process of forming glass by cooling a substance without crystallization, resulting in a short-range atomic structure. Devitrification occurs when crystals form in glass at high temperatures over long periods. Glass ceramics contain both glass and crystalline phases, making them harder and stronger but less translucent than glass. Dental porcelain is a ceramic used for dentures, crowns, and porcelain fused to metal restorations.

Biodegradable_Polymers_Use_In_dental_Application.pptx
Biodegradable polymers can be used in dental applications as an alternative to past techniques. Specifically, homopolymers of lactide and copolymers of lactide and glycolide are biodegradable polyesters like polylactic acid, polyglycolic acid, and polylactic-co-glycolic acid that degrade into natural metabolites. These biodegradable polymers have properties making them suitable for use as membranes in guided bone regeneration or as bone grafting materials, and they degrade within months into carbon dioxide and water.
Chipping Fracture Resistance Of Dental CAD-CAM Restorative Materials.pptx
This document discusses methods for evaluating the chipping fracture resistance of dental CAD/CAM restorative materials. It describes several parameters used to measure chipping resistance, including brittle index, edge toughness, edge chip power law, and chipping factor. Different types of indenters are also evaluated for their effect on chipping test results. Comparative results are presented for various dental materials, showing relationships between brittleness index and chipping factor, as well as differences in chipping resistance curves based on indenter type. Edge chip power law is found to better fit data than edge toughness, especially at greater distances from the edge.
Evaluation Methods of Depth of Cure for Dental.pptx
This document discusses various methods for evaluating the depth of cure of dental resin composite materials, including thickness measurements, scraping technique, hardness tests, atomic force microscopy, glass transition temperature measurements, and degree of conversion measurements using differential scanning calorimetry and Fourier transform infrared or micro-Raman spectroscopy. No single technique can fully characterize the complex curing behavior, so a combination is typically used to evaluate factors like light absorption, scattering, filler properties, and how well material cures at different depths.
