This article provides an illustrative description of the pre-post difference index (PPDI), a simple, nontechnical yet robust tool for examining the instructional sensitivity of assessment items. Extension educators often design pretest-posttest instruments to assess the impact of their curricula on participants' knowledge and understanding of the…

Secondary teachers participating in summer professional development chemistry workshops in Texas used an online chemistry tutoring program, OWL Quick Prep (Day et al. in OWL: Online Web-based Learning, Brooks-Cole Cengage Learning, Florence, KY, 1997) as a part of the inservice training. Self-reported demographic data were used to identify factors…

First- and second-grade students in two intact multiage classrooms were engaged in three read-aloud sessions with thematically related trade books, each portraying a scientist involved in authentic investigation. One group engaged in discussion of text ideas during reading, whereas the other group engaged in discussion only at the conclusion of…

This study explored how teacher variations in use of a web-technology of known effectiveness, affected growth in literacy. Teachers used ABRACADABRA (ABRA) (http://grover.concordia.ca/abra/version1/abracadabra.html), in Grade 1 Language Arts classes. Children (N = 60) across three classrooms were exposed to ABRA activities and a control class…

This study explores the relationship between teacher knowledge and student learning in the area of mathematics by developing and evaluating an innovative approach to assessing teacher knowledge. This approach is based on teachers' analyses of classroom video clips. Teachers watched 13 video clips of classroom instruction and then provided written…

This article discusses the development and implementation of a technology-supported student teacher performance assessment that supports integration with a larger electronic assessment system. The authors spearheaded a multidisciplinary team to develop a comprehensive performance assessment based on the Pathwise framework. The team collaborated…

The study examined the efficacy of an intensive form of professional development (PD) for building the knowledge of first-grade teachers in the areas of phonological awareness and phonics. The PD featured frequent in-class support from highly knowledgeable mentors for one school year, in addition to an introductory two-day summer institute and…

The goal of the X-Tech project was to enhance preservice teachers' perceptions of their preparedness to teach with technology. Results indicated that practically-oriented methods that meet a variety of technology related needs are viable for attaining such a goal. Further, it is particularly beneficial to have teachers use a variety of resources…

No other food industry depends so heavily on a wild caught resource than those associated with aquatic food products. Domestication of fish, shellfish, and other aquatic resources production has lagged behind other terrestrial livestock products; however, demand for these aquatic natural resources has continued to increase dramatically. Teaching…

Using a pretest-posttest quasi-experimental control group design, a learning environment study was conducted to evaluate the environmental literacy of postsecondary, nonscience majors. Data were collected from 183 students taking an introductory environmental science class--a 41-question Environmental Literacy Instrument (ELI) prompted students…

This paper reports on an intervention study which investigated the effect of teaching English phonotactics upon Arabic speakers' lexical segmentation of running speech in English. The study involved a native English-speaking group (N = 12), a non-native control group (N = 20); and a non-native experimental group (N = 20). Each group was pre-tested…

This study examines the use of engineering design to facilitate science reasoning in high-needs, urban classrooms. The Design for Science unit utilizes scaffolds consistent with reform science instruction to assist students in constructing a design solution to satisfy a need from their everyday lives. This provides a meaningful context in which…

This study is an analysis of the effectiveness of a faculty-designed laboratory experience about a difficult topic, cellular respiration. The activity involves a hands-on model of the cellular-respiration process, making use of wooden ball-and-stick chemistry models and small toy trucks on a table top model of the mitochondrion. Students…

The aim of this study was to explore the extent to which the characteristics of two teaching interventions can bring about cognitive progress in preschoolers with regard to the factors rolling friction depends on, when it is applied to an object that is freely rolling on a horizontal surface. The study was conducted in three phases: pre-test,…

The benefits of multisensory instruction for teaching mathematics to students in resource rooms were explored. Participants were third and fourth graders (n = 12) in 3 resource rooms for replacement mathematics in a middle-class school district in New Jersey. The students received weekly instruction for several months, using manipulatives and word…
