Data collected in many biology laboratory classes are on ratio or interval scales where the size interval between adjacent units on the scale is constant, which is a critical requirement for analysis with parametric statistics such as t-tests or analysis of variance. In other cases, such as ratings of disease or behavior, data are collected on…

This paper provides practical guidance for scholars and practitioners looking to develop more rigorous, comprehensive, and inclusive research that could guide proactive efforts to improve access, experiences, and outcomes for college students with disabilities. To do so, we (a) identify critical challenges affecting research and assessment related…

The fruit fly ("Drosophila melanogaster") is an ideal subject for studying inheritance patterns, Mendel's laws, meiosis, Punnett squares, and other aspects of genetics. Much of what we know about genetics dates to evolutionary biologist Thomas Hunt Morgan's work with mutated fruit flies in the early 1900s. Many genetic laboratories…

In the era of Big Data, because of diminishing cost of data collection and storage, a large number of statistical tests may even possibly be conducted all together by a high school student to seek for some "exciting" new scientific findings. In this article, we propose an interesting approach to introduce students to some important…

Every high school graduate should be able to use data analysis and statistical reasoning to draw conclusions about the world. Two core statistical concepts for students to understand are the role of variability in measures and evaluating the effect of a variable. In the activity presented in this article, students investigate a scientific question…

An exciting event had occurred for the grade 3 classes at Woodlands State School. A new play space designated for the older grades had now been opened to the third graders. In sharing their excitement over this "real treat, real privilege," the teachers invited the children to find out more about playgrounds and, in particular, their new…

Cell water relationships are important topics to be included in cell biology courses. Differences exist in the control of water relationships in plant cells relative to control in animal cells. One important reason for these differences is that turgor pressure is a consideration in plant cells. Diffusion and osmosis are the underlying factors…

Reasoning about and making sense of statistics and probability are essential to students' future success. This volume belongs to a series that supports National Council of Teachers of Mathematics' (NCTM's) "Focus in High School Mathematics: Reasoning and Sense Making" by providing additional guidance for making reasoning and sense making part of…

This study examined the perceptions of teachers on the effectiveness of organizational communication in their schools and whether the perceptions differed between teachers in primary and junior high schools as a function of gender, age, marital status, seniority, and rank. Data were collected from a sample of 334 teachers in 63 schools, working in…

This book is a guide to categorizing, measuring, testing, and assessing aspects of language, and is intended for language teachers, speech therapists and other language-related practitioners, and researchers, in conjunction with other resources on research methods and statistics. The first part is a discussion of basic terminology and the varied…

Created by teachers for teachers, the Math Academy tools and activities included in this booklet were designed to create hands-on activities and a fun learning environment for the teaching of mathematics to the students. This booklet contains the "Math Academy--Play Ball! Explorations in Data Analysis & Statistics," which teachers can use to…

An example of real-world data is used to introduce comprehensible and visual images of the data and their attributes and relationships. Stem-and-leaf plots, box-and-whisker plots, and scattergrams are used to encourage prompt recognition of data characteristics and to effect appropriate interpretations and inferences. (JJK)

Evaluation can be crucial to help meet the needs and requirements of the teacher, students, and curriculum in distance education. Distance education usually encompasses a wide diversity of students, multi-site classrooms, little opportunity for interaction among students, and unfamiliar technology. Because of these uncertainties, evaluation of…

The linking of research and action, basic methods of social research, and the uses of research in distance teaching are examined, with examples drawn from the Lesotho Distance Teaching Centre and other distance teaching programs. Ways in which research can be useful and early stages of research design and planning are discussed. An explanation of…

This report includes a collection of workshop materials which address ways microcomputers can be used in evaluation and assessment and what basic information should be covered in introducing newcomers to the use of microcomputers. It is designed for use by experienced trainers with microcomputer experience but with few workshop support materials.…
