Curriculum-based measurement yearly growth rates: An examination of English Language Learners and native English speakers

The use of curriculum-based measurement (CBM) is supported by several decades of research regarding their technical adequacy, practical utility, and use with diverse populations. Questions remain regarding the measurement of growth using tri-annual reading CBM (R-CBM) assessment. Existing research on annual rates of growth is inconclusive with some studies suggesting that the most growth occurs from the fall to the winter and others finding growth accelerates from winter to spring. With a sample of students in third through fifth grades, consisting of a high percentage of English Language Learners (ELLs) and students exited from bilingual instruction, this study found that Non-ELL students demonstrated semester differences in R-CBM growth consistent with prior research in third and fourth grades, but not in fifth grade. However, this pattern was not always consistent for ELLs and students recently exited from bilingual instruction, suggesting that conclusions regarding semester differences in R-CBM growth rates should not be consistently extended to ELLs.     

Serial overshadowing of taste aversion learning by stimuli preceding the target taste

Three experiments tested whether events taking place before a rat has access to a target taste, sucrose, can proactively interfere with the acquisition of a sucrose aversion when sucrose is followed by a lithium chloride injection. Using a serial overshadowing procedure with various delays before lithium injection, proactive interference by a taste (Experiments 1 and 3) and by a novel context (Experiment 2) was found following two conditioning sessions, but not after a single conditioning session. Conversely, overshadowing by a taste given after the target was detectable after a single conditioning trial (Experiment 3) and, thus, indicated that retroactive interference involves a process different from that producing proactive interference. A simulation confirmed that the results are consistent with a modified Rescorla and Wagner (1972) interpretation of Revusky??s (1971) concurrent interference theory of delay learning.     

Evaluating interactivity and learning in computer conferencing using content analysis techniques

This paper outlines the application of a particular model of content analysis to the evaluation of an online discussion group. A set of online discussion data from a group of students enrolled in an educational management course offered by the Open University of Hong Kong (OUHK) was examined. The provision of the online discussion facility for this group of students was mainly for enrichment purposes and their participation was completely voluntary. Overall, the analysis confirmed the usefulness of Henri’s model in examining the interaction and learning processes in an online forum. It also provided insights towards increased understanding of the complex processes and methodological considerations involved in analysing online conferences.     

Genetics Reasoning with Multiple External Representations

This paper explores a case study of a class of Year 10 students (n=24) whose learning of genetics involved activities of BioLogica, a computer program that features multiple external representations (MERs). MERs can be verbal/textual, visual-graphical, or in other formats. Researchers claim that the functions of MERs in supporting student learning are to complement information or processes, to constrain the interpretation of abstract concepts, and to construct new viable conceptions. Over decades, research has shown that genetics remains linguistically and conceptually difficult for high school students. This case study using data from multiple sources enabled students' development of genetics reasoning to be interpreted from an epistemological perspective. Pretest-posttest comparison after six weeks showed that most of the students (n=20) had improved their genetics reasoning but only for easier reasoning types. Findings indicated that the MERs in BioLogica contributed to students' development of genetics reasoning by engendering their motivation and interest but only when students were mindful in their learning. Based on triangulation of data from multiple sources, MERs in BioLogica appeared to support learning largely by constraining students' interpretation of phenomena of genetics.     

Applying the Structure of the Observed Learning Outcomes (SOLO) Taxonomy on Student's Learning Outcomes: An empirical study

This article explores the application of different educational taxonomies in measuring students' cognitive learning outcomes. The objectives were to compare three educational taxonomies--namely, the Structure of the Observed Learning Outcomes (SOLO) taxonomy, Bloom's taxonomy and reflective thinking measurement model--and to test the application value of these taxonomies. A comparative literature review was conducted to provide an underlying conceptual framework. Recommendations from this review were examined experimentally. Scripts of long essay papers and short classroom discussion responses were analyzed by the modified versions of the taxonomies. It was found that SOLO is suitable for measuring different kinds of learning outcomes. However, finer categorization of SOLO levels did not eradicate the problem of SOLO's conceptual ambiguity. It is suggested that the next step of research should be on setting up panels of judges to find out which taxonomy is suitable for measuring what learning outcomes under which contexts.     

Pre‐service Teachers' Conceptions about Teaching and Learning: A closer look at Singapore cultural context

A questionnaire was administered to 313 teacher education students of the National Institute of Education, Nanyang Technological University, Singapore to examine their conceptions about teaching and learning. Two dimensions were identified, viz. traditional and constructivist conceptions about teaching and learning. While both conceptions were prevailing, there was a greater tendency for students to hold a constructivist conception about teaching and learning. Multivariate data analysis showed that there were significant differences in the two conceptions about teaching and learning across program groups, among different race groups, with respect to qualifications, but no significant differences for age, gender and subject groups. Explanations were sought in the ambit of educational initiatives and cultural premises. Implications were also drawn for future development and planning in teacher education.     

Successful Treatment of a Noise Phobia in a Nine‐year‐old Girl with Systematic Desensitisation in vivo

A nine‐year‐old girl with a severe noise phobia was successfully treated in 10 sessions of in vivo desensitisation. Gains were maintained at three month follow‐up.
