W. Norton strives to produce high-ยญquality, valid, and reliable assessment supplements according to the following criteria. โ€ข TOP: This references the topic, taken from the chapter heads, that is tested by the question. โ€ข MSC: This is the level of Bloomโ€™s Taxonomy that the question is designed to test. For more information, please see โ€œBloomโ€™s Taxonomyโ€ below. STUDENT COMPETENCIES AND EVIDENCE- ยญCENTERED DESIGN A good assessment tool must: 1. define what students need to know and the level of knowledge and skills that constitute competence in the concepts about which they are learning; 2. include test items that provide valid and reliable evidence of competence by assessing the material to be learned at the appropriate level; and 3. enable instructors to judge accurately what students know and how well they know it, thus allowing instructors to focus on areas where students need the most help. ASSESSMENT INFORMATION ยญEvery question is labeled with six levels of metadata to ยญ hese metadata allow instructors to assess their students. T tags are: โ€ข ANS: This is the correct answer for each question. โ€ข DIF: This is the difficulty assigned to the probยญlem. Probยญlems have been classified as Easy, Moderate, or Difficult. โ€ข OBJ: This is the learning objective, taken from the instructorโ€™s manual, that the question is intended to assess. BLOOMโ€™S TAXONOMY ยญ hese question types are informed by Bloomโ€™s Taxonomy. T We have focused on the levels of Bloomโ€™s taxonomy that are most relevant to physical anthropology and are most reliably assessed through the types of questions included in this test bank. 1. Remembering questions test declarative knowledge, including textbook definitions and relationships between two or more pieces of information. Can students recall or remember the information in the same form it was learned? 2. Understanding questions pose probยญlems in a context difยญferยญent from the one in which the material was learned, requiring students to draw from their declarative and/or procedural understanding of imporยญtant concepts. Can students explain ideas or concepts? 3. Applying questions ask students to draw from their prior experience and use critical-ยญthinking skills to reason about the real world. Can students use learned information in new situations? 4. Analyzing questions test studentsโ€™ abilities to break down information and see how difยญferยญent eleยญments relate ยญ hole. Can students distinguish to each other and to the w among the difยญferยญent parts? viii | Introduction 5. Evaluating questions ask students to assess information as a ยญwhole and frame their own arguments. Can students make decisions and distinguish between valid and invalid claims? DIFFICULTY LEVELS 1. Easy questions require a basic understanding of the concepts, definitions, and examples presented in the textbook. 2. Moderate questions direct students to use critical thinking skills and to demonstrate an understanding of core concepts inยญdeยญpenยญdent of specific textbook examples or definitions. 3. Difficult questions ask students to synthesize textbook concepts to make analytical inferences or to evaluate claims. GENERAL RULES FOR NORTON ASSESSMENT Each question meaยญsures and links explicยญitly to a specific concept and objective and is written in clear, concise, and grammatically correct language that suits the difficulty level of the material being assessed. To ensure the validity of questions, no extraneous, ambiguous, or confusing material is included, and no slang expressions are used. In developing the questions, ยญevery effort has been made to eliminate bias (e.g., race, gender, cultural, ethnic, regional, disability, age, and so on) to require specific knowledge of the material studied, not general knowledge or experience.

Discuss the six key attributes that make humans unique relative to other species. ANS: The six distinguishing features of humanity are bipedalism, nonhoning canines, complex material culture and tool use, hunting, speech, and dependence on domesticated food. Note that the order in which these attributes appear, and their timing, can be important parts of a complete and correct answer. The commitment to walking on two legs is usually considered the most profound physical difference between humans and other primates. After bipedalism, according to the fossil record, the large honing canine tooth was lost as a result of the ability to make and use tools for processing food. Culture, involving learned behavior transmitted from person to person, facilitates survival through adaptation to varied settings. Material culture is the part of culture that is expressed as objects that humans use to manipulate our environment. The archaeological record of past culturesโ€™ material remains goes back to the simple rock tools that date from 2.5 mya. Humans require some form of technology to regulate temperature, acquire food, and so on in our varied environments. Some chimpanzees and other primates have simple material culture and even nonmaterial culture. Humansโ€™ other key attributesโ€”hunting, speech, and dependence on domesticated foodsโ€”appeared much later in human evolution. Hunting refers to cooperative hunting, which likely emerged 1 million or more years ago. Speech is very distinctive of humans but difficult to pinpoint in the fossil record. Domestication of foods is the most recently developed unique human behavior, usually traced to 10,000 years ago. Increasing dependence on culture for survival makes us quite distinct among species and necessitates a biocultural approach to both human origins and human behavior.

ANS: A hypothesis is a proposed explanation for an observation that can be tested with further analysis or an experiment. Example: Darwinโ€™s idea that bipedalism was linked to humans shifting from the trees to the ground. It was based on available observations of primate and humans working, and it was testable using anatomical evidence. A theory is an evidence-based explanation for some aspect of nature based on a great deal of well-documented information and is much more complicated and well-tested than a hypothesis. (The word theory in common language is often used to mean the opposite, referring to ideas that are not well developed or supported.) Example: The idea that life has changed over time as part of the process described by Darwin and other scientists, giving rise to new species, known as a theory of evolution. Scientific laws are few in number and describe a straightforward and irrefutably true relationship or phenomenon in nature. Though a theory is complex and based on excellent evidence, it is subject to revision and refinement over time. A scientific law is simpler and extremely unlikely to ever be proven entirely wrong. Example: Gravity is an irrefutable phenomenon and is incredibly unlikely to ever be disproven. DIF: Difficult OBJ: Distinguish between hypotheses and theories. TOP: How We Know What We Know: The Scientific Method MSC: Analyzing | Applying 3. Provide a short description of the steps of the scientific method. ANS: The scientific method includes observations, development of a hypothesis to explain the observations, experimentation to test the hypothesis, systematic collection of data, and development conclusions based on evidence. If the data support the hypothesis, more testing is done. If the data refute the hypothesis, then the hypothesis needs to be changed or replaced. DIF: Moderate OBJ: Explain the four steps involved in โ€œdoing scienceโ€ (i.e., the scientific method). TOP: How We Know What We Know: The Scientific Method MSC: Analyzing 4. Provide an imaginary example of the proper use of the scientific method. ANS: This answer should include only examples of what can be tested. It should make reference to empirical data collected by experiment or observation. The studentโ€™s response should include each step of the scientific method along with a fictional conclusion. There should be a clear reference to the development and testing of hypotheses. This question may even be used on the first day of class as an icebreaker of sorts after a thorough lecture on the scientific method.

ANS: The response should include discussions of pharmaceutical and medical testing or other important policy-related science (climate change, technology, etc.). The student should show comprehension of the value of testing and retesting data. For example, do immunization shots administered all at once increase the childโ€™s likelihood to develop autism? The answer, we know, is that they do not; however, previous doctored data were used to claim that they do, causing millions of parents all over the world to reduce inoculations or completely neglect them, thereby increasing the incidence of diseaseโ€”for example, the number of whooping cough cases in the United States.
