  • My personal experience with research paper writing services was highly positive. I sent a request to ⇒ www.HelpWriting.net ⇐ and found a writer within a few minutes. Because I had to move house and I literally didn’t have any time to sit on a computer for many hours every evening. Thankfully, the writer I chose followed my instructions to the letter. I know we can all write essays ourselves. For those in the same situation I was in, I recommend ⇒ www.HelpWriting.net ⇐.

  • I’ve personally never heard of companies who can produce a paper for you until word got around among my college groupmates. My professor asked me to write a research paper based on a field I have no idea about. My research skills are also very poor. So, I thought I’d give it a try. I chose a writer who matched my writing style and fulfilled every requirement I proposed. I turned my paper in and I actually got a good grade. I highly recommend ⇒ www.WritePaper.info ⇐

  64. 64. Reading comprehension • Bem (1975) has argued that androgynous people are “better off” than their sex-typed counterparts because they are not constrained by rigid sex-role concepts and are freer to respond to a wider variety of situations. Seeking to test this hypothesis, Bem exposed masculine, feminine, and androgynous men and women to situations that called for independence (a masculine attribute) or nurturance (a feminine attribute). The test for masculine independence assessed the subject’s willingness to resist social pressure by refusing to agree with peers who gave bogus judgments when rating cartoons for funniness (for example, several peers might say that a very funny cartoon was hilarious). Nurturance or feminine expressiveness, was measured by observing the behavior of the subject when left alone for ten minutes with a 5-month old baby. The result confirmed Bem’s hypothesis. Both the masculine sex- typed and the androgynous subjects were more independent (less conforming) on the ‘independence” test than feminine sex-typed individuals. Furthermore, both the feminine and the androgynous subjects were more “nurturant” than the masculine sex-typed individuals when interacting with the baby. Thus, the androgynous subjects were quite flexible, they performed as masculine subjects did on the “feminine” task. 64 35. What is the independent variable in the study? a. Situations calling for independence and nurturance b. Situation to make the sex type react c. Situations to make the androgynous be flexible d. Situations like sex type, androgynous and sex role concepts 36. What are the levels of the IV? a. masculine attribute and feminine attribute b. rating cartoons and taking care of a baby c. independence and nurturance d. flexibility and rigidity
  65. 65. Interpreting Diagrams Instruction. Study the following illustrations and answer the following questions. Figure 1 65 Pretest Posttest 101. Which group received the treatment? a. group A b. group B b. c. none of the above 102. Why did group B remain stable across the experiment? a. there is an EV b. there is no treatment c. there is the occurence of ceiling effect 103. What is the problem at the start of the experiment? a. the groups are nonequivalent b. the groups are competing with each other c. the treatment took place immediately
  66. 66. Characteristics of performance-based assessment • Students perform, create, construct, produce, or do something. • Deep understanding and/or reasoning skills are needed and assessed. • Involves sustained work, [often days and weeks]. • Calls on students to explain, justify, and defend. • Performance is directly observable. • Involves engaging in ideas of importance and substance. • Relies on trained assessor’s judgments for scoring • Multiple criteria and standards are prespecified and public • There is no single correct answer. • If authentic, the performance is grounded in real world contexts and constraints.

  79. 79. Example of Performance-based task • Final Product • Chemists are often required to determine the concentration of unknown acidic or basic solutions. You will be provided with an unknown solution that is either acidic or basic. Your problem is to design an experiment, using the materials (and/or others) listed below, to determine the concentration of the unknown solution provided. Express your concentration of the unknown material in moles of H+ (aq) per liter or moles of OH- (aq) per liter of solution.

  83. 83. Rating Scales • Indicate the degree to which a particular dimension is present. • Three kinds: – Numerical – Qualitative – Combined Qualitative and Quantitative
  84. 84. Rating Scale • Numerical Scale – Numbers of a continuum to indicate different level of proficiency in terms of frequency or quality Example: Complete Understanding 5 4 3 2 1 No understanding Clear organization 5 4 3 2 1 No organization Fluent reader 5 4 3 2 1 Emerging reader
  85. 85. Rating Scale • Qualitative scale – Uses verbal descriptions to indicate student performance. – Provides a way to check the whether each dimension was evidenced. • Type A: Indicate different gradations of the dimension • Type B: Checklist
  86. 86. Rating Scale • Example of Type A: – Minimal, partial, complete – Never, seldom, occasionally, frequently, always – Consistent, sporadically, rarely – None, some, complete – Novice, intermediate, advance, superior – Inadequate, needs improvement, good excellent – Excellent, proficient, needs improvement – Absent, developing, adequate, fully developed – Limited, partial, thorough – Emerging, developing, achieving – Not there yet, shows growth, proficient – Excellent, good, fair, poor
  87. 87. Rating Scale • Example of Type A: Checklist
  88. 88. Rating Scale • Holistic scale – The category of the scale contains several criteria, yielding a single score that gives an overall impression or rating Example level 4: Sophisticated understanding of text indicated with constructed meaning level 3: Solid understanding of text indicated with some constructed meaning level 2: Partial understanding of text indicated with tenuous constructed meaning level 1: superficial understanding of text with little or no constructed meaning
  89. 89. Example holistic scale
  90. 90. Analytic scale • Analytic Scale – One in which each criterion receives a separate score. Example Criteria Outstanding 5 4 Competent 3 Marginal 2 1 Creative ideas Logical organization Relevance of detail Variety in words and sentences Vivid images
  91. 91. Rubrics • When scoring criteria are combined with a rating scale, a complete scoring guideline is produced or rubric. • A scoring guide that uses criteria to differentiate between levels of student proficiency.
  92. 92. Example of a rubric
