Encoding and retaining information in the visuals and verbals of an educational movie

This study shows that when viewers watching an educational movie are presented simultaneously with information in two media-visual and verbal /auditory, there is no competition fa resources. When encoding information in one medium, one is not hindered from encoding information in the other; even when visual and linguistic information are presented sequentially, doubling study time, the extraction of information is not increased. College students appear to be good dual media processors.

“You can go to college”: Employing a Developmental Perspective to Examine How Young Men of Color Construct a College-Going Identity

This article examines college-going identity construction for Black, Latino, and Asian American and Pacific Islander high school students. The authors use Marcia’s (J Personal Soc Psychol 3(5):551–558, 1966; in: Delson (ed) Handbook of adolescent research, Wiley, New York, 1980) ego identity statuses perspective to examine how students develop their college-going identities to consider their post-high school pathways. We draw on focus groups interviews with 153 Black, Latino, and Asian American Pacific Islanders students enrolled in 10 urban and suburban high schools in California. The findings show the importance of being somebody, not quitting before establishing a career or graduating from college, joining the military as a pathway to finance postsecondary education, and the internal pressure to pay for higher education. The significance of this paper challenges the dominant narrative of young men of color not invested or interested in higher education, but highlight how the young men of color negotiate their agency in constructing their ideas and making decisions based on how various tensions and aspirations shape their goals after high school.     

Missing the Mark: A New Form of Honorary Authorship Motivated by Desires for Inclusion

As scientific teams in academia have become increasingly large, interdisciplinary, and diverse, more attention has been paid to honorary authorship (i.e., giving authorship to those not making a significant contribution). Our study examined whether honorary authorship occurs because of the desire to include all or many team members. Interviews with project principal investigators (n?=?6) and early-career project members (n?=?6) from 6 interdisciplinary environmental science research teams revealed that principal investigators frequently employed inclusion-motivated honorary authorship but that this practice had some negative impacts on early-career team members with less power and status, thereby undermining true inclusion of those from underrepresented groups. We believe our findings are of import not only for environmental scientists, but also for scholars who are interested in issues of authorship decision-making regardless of disciplinary affiliation.

Reducing the distance: equity issues in distance learning in public education

Distance learning and educational equity both began with an emphasis on access, on providing underserved students with an increased access to education. Today definitions of equity have gone beyond simple access to include equal or equivalent treatment and outcomes while definitions of underserved students have expanded to include girls, children of color, children with limited English proficiency and children with disabilities. At the same time the definition of distance learning has expanded to include new technologies, new audiences and new roles. Based on these new definitions and roles, the article raises a number of equity challenges for distance learning educators centering around who is taught, what is taught and how the teaching is done. To answer these challenges, a series of recommendations are suggested that educators can implement to make distance learning a leader in increasing educational equity for all students. The time to act is now.     

Improving research on computers in science learning

Although research in Computer Assisted Instruction (CAI) currently lacks a well-developed literature and experimental foundation, the number of papers relating to CAI at the 1985 NARST convention at French Lick Springs increased substantially over those presented at the 1984 meeting. This commentary critiques some of those papers and suggests implications for the conduct of research on computers in science learning. The spirit of inquiry and the willingness to share ideas at the 1985 NARST meeting at French Lick Springs enhanced the quality of the meeting and made possible the gathering of papers and information that are the basis for this commentary. One team of authors (Choi & Gennaro, 1985) was so generous as to provide us with software they had developed for their study. The willingness to share was impressive and can facilitate research and development.     

Assessing students’ ability in performing scientific inquiry: instruments for measuring science skills in primary education

Background With the increased attention on the implementation of inquiry activities in primary science classrooms, a growing interest has emerged in assessing students’ science skills. Research has thus far been concerned with the limitations and advantages of different test formats to assess students’ science skills.

Purpose This study explores the construction of different instruments for measuring science skills by categorizing items systematically on three subskill levels (science-specific, thinking, metacognition) as well as on different steps of the empirical cycle.

Sample The study included 128 fifth and sixth grade students from seven primary schools in the Netherlands.

Design and method Seven measures were used: a paper-and-pencil test (PPT), three performance assessments, two metacognitive self-report tests, and a test used as an indication of general cognitive ability.

Results Reliabilities of all tests indicate sufficient internal consistency. Positive correlations between the PPT and the three performance assessments show that the different tests measure a common core of similar skills thus providing evidence for convergent validity. Results also show that students’ ability to perform scientific inquiry is significantly related to general cognitive ability. No relationship was found between the measure of general metacognitive ability and either the PPT or the three performance assessments. By contrast, the metacognitive self-report test constructed to obtain information about the application of metacognitive abilities in performing scientific inquiry, shows significant – although small – correlations with two of the performance assessments. Further explorations reveal sufficient scale reliabilities on subskill and step level.

Conclusions The present study shows that science skills can be measured reliably by categorizing items on subskill and step level. Additional diagnostic information can be obtained by examining mean scores on both subskill and step level. Such measures are not only suitable for assessing students’ mastery of science skills but can also provide teachers with diagnostic information to adapt their instructions and foster the learning process of their students.     

Resident rats’ aggression toward intruders

A study was performed in which attacks by four different types of “resident” rat (males housed with fertile females, males housed with sterile females, paired males, and isolated males) on six different types of intruder (isolated males, grouped males, castrated males, isolated females, grouped females, and ovariectomized females) were investigated. The objective was to study features of resident and intruder rats that would allow the designing of an aggression test that used a minimum of animals and produced a rapid behavioral response. In some combinations of residents and intruders, attack was generated within a 10-min test period. Isolated resident males attacked as much as males housed with females; however, paired rats showed only low incidences of attack. The fertility of the female partner did not influence the male’s aggressiveness. Most male attacks were directed towards like-sexed intruders. Only isolated males differentiated between the different treatment types of male intruder, attacking group-housed and castrated rats less intensely than isolates. Of the females, only those that were fertile produced significant amounts of attack behavior and almost exclusively attacked female intruders. Group-housed intruder females received more attacks than isolates. The results suggest optimal conditions for generating two models of attack behavior in the laboratory rat.
