This study examined the effects of prior knowledge, learner preference for control, and type of control (learner or program)
on the achievement of middle-school students in a computer-based instructional program on adding and subtracting integers.
Students were blocked by preference-for-control scores and randomly assigned to either a learner-control or program-control
version of instruction. A significant three-way interaction (prior knowledge × preference scores × type of control) revealed
that students with high prior knowledge achieved better on the posttest when their preference for control was matched with
the type of control they received, whereas students with low prior knowledge achieved better when their preference was mismatched.
A significant three-way interaction on attitude reflected the same pattern found in the interaction for achievement scores.
The overall results indicate that matching learner preference to the type of program they receive is an effective strategy
for high-prior-knowledge students but not for those with low prior knowledge.

Referential perspective and instruction: A study on teacher-student interaction and text remembering
The aim of this paper is to study the role ofteacher-student interaction, in the acquisitionof text comprehension and memory skills from asocio-cultural approach. In our view, one ofthe most important areas of neglect in cognitive research in this field is the interactional nature of that development. We intend to establish the way in which teacher-student interaction and, specially, the use of some specific semiotic means mayfacilitate the acquisition and internalizationof general strategies for understanding andremembering expository texts. The role ofreferential perspective (Wertsch, 1989) in theinternalization of complex text study actionsis analysed.The task was to study three expository textsthat were similar in their structure. Thecontent of the texts was analysed in terms ofidea-units (Meyer, 1984). Each text was formedby idea-units from three different levels: mainideas, secondary ideas and details. A categorysystem for the analysis of study and recall ofthe text is developed. In the study phase theanalysis proceeded in two steps: study actionsand text ideas. In the recall phase, two types ofindexes (number of ideas and degree ofclustering) were considered. For the analysisof instructional actions, both the nature ofinstruction and referential perspective wasrecorded. 相似文献

The time, material, and staff‐consuming nature of anatomy's traditional pen‐and‐paper assessment system, the increase in the number of students enrolling in medical schools and the ever‐escalating workload of academic staff have made the use of computer‐based assessment (CBA) an attractive proposition. To understand the impact of such shift in the assessment method, an experimental study evaluating its effect on students’ performance was designed. Additionally, students’ opinions toward CBA were gathered. Second‐year medical students attending a Clinical Anatomy course were randomized by clusters in two groups. The pen‐and‐paper group attended two sessions, each consisting of a traditional sectional anatomy steeplechase followed by a theoretical examination, while the computer group was involved in two similar sessions conducted in a computerized environment. At the end of each of the computer sessions, students in this group filled an anonymous questionnaire. In the first session, pen‐and‐paper group students scored significantly better than computer‐group students in both the steeplechase (mean ± standard deviation: 66.00 ± 14.15% vs. 43.50 ± 19.10%; P < 0.001) and the theoretical examination (52.50 ± 12.70% vs. 39.00 ± 21.10%; P < 0.001). In the second session, no statistically significant differences were found for both the steeplechase (59.50 ± 17.30% vs. 54.50 ± 17.00%; P = 0.085) and the theoretical examination (57.50 ± 13.70% vs. 54.00 ± 14.30%; P = 0.161). Besides, an intersession improvement in students’ perceptions toward CBA was registered. These results suggest that, after a familiarization period, CBA might be a performance equivalent and student accepted alternative to clinical anatomy pen‐and‐paper theoretical and practical examinations.
