The effects of Common Knowledge Construction Model sequence of lessons on science achievement and relational conceptual change

The purpose of this study was to investigate the effects of the Common Knowledge Construction Model (CKCM) lesson sequence, an intervention based both in conceptual change theory and in Phenomenography, a subset of conceptual change theory. A mixed approach was used to investigate whether this model had a significant effect on 7th grade students' science achievement and conceptual change. The Excretion Unit Achievement Test (EUAT) indicated that students (N = 33) in the experimental group achieved significantly higher scores (p < 0.001) than students in the control group (N = 35) taught by traditional teaching methods. Qualitative analysis of students' pre‐ and post‐teaching conceptions of excretion revealed (1) the addition and deletion of ideas from pre‐ to post‐teaching; (2) the change in the number of students within categories of ideas; (3) the replacement of everyday language with scientific labels; and (4) the difference in the complexity of students' responses from pre‐ to post‐teaching. These findings contribute to the literature on teaching that incorporates students' conceptions and conceptual change. © 2009 Wiley Periodicals, Inc. J Res Sci Teach 47: 25–46, 2010     

Effective Writing Assessment and Instruction for Young English Language Learners

The total number of English Language Learners in the American public schools is more than 4.5 million students or 9.6% of the total school population. This article focuses on instructional writing strategies and assessments for English Language Learners in the elementary classroom. This article provides early childhood education teachers with information about differences amongst English Language Learners because they are not a homogenous group. English Language Learners’ academic abilities can range from emergent readers, writers, and speakers of English to proficient readers, writers, and speakers of English.     

Making a Difference in the Lives of Youth: Mapping Success with the “Six Cs”

Many museums offer specialized programs for young people during out‐of‐school time, yet the consequences of such programs are not well documented. This article explores the potential utility of borrowing a conceptual framework from the youth development literature as a tool for assessment. The authors map findings from three studies of museum youth programs onto the youth development framework as an exercise in understanding the extent to which this model may be useful in developing museum youth programs. Results from this preliminary analysis demonstrate that the framework could serve as a viable tool for program design, and could offer a clear, grounded framework with common language for articulating program impacts often known intuitively and/or anecdotally but not formalized.

Experiences of Being Heterosexual Allies to Lesbian,Gay, and Bisexual People: A Qualitative Exploration

In this qualitative study, heterosexual professionals with an interest in lesbian, gay, and bisexual (LGB) issues were surveyed about their ally work with LGB people. Data were analyzed to describe participants' experiences. Results are discussed in terms of implications for counseling and student affairs professionals who engage in LGB‐affirmative work.     

Sign tracking in domesticated quail with one trial a day: Generality across CS and US parameters

When the conditioned stimulus (CS) is located some distance from the unconditioned stimulus (US), pairings of the CS and US can yield either conditioned approach to the CS (sign tracking) or conditioned approach to the US (goal tracking). However, goal tracking is the more common outcome, and, because of that, goal tracking has come to serve as a “standard” measure of associative learning in several laboratories. In contrast, in previous studies of sexual conditioning with domesticated quail, only sign tracking was observed. In the present study, quail continued to show sign tracking rather than goal tracking whether or not the US was highly localized (Experiment 1), whether food or a sexual US was used (Experiment 2), whether the CS was mobile or immobile (Experiment 3), and whether the CS was 91 or 233 cm from the US compartment (Experiment 4). The present findings encourage caution in the routine use of goal tracking as a measure of learning. The possible mechanisms of goal tracking are discussed in terms of occasion setting and behavior systems theory.
