PROCESSUS DE RECHERCHE D’INFORMATION (suite)
Élaborer des stratégies de recherche – Réajuster les stratégies
Difficultés techniques pb: difficulté à visualiser abstraitement la séquence de l’alphabet et à évaluer la distance entre deux notices (pour les élèves du primaire) | Hooten, 1992; Edmonds et al., 1990; Solomon, 1994 (cf. Brodeur, 1996) |
pb: even among high school students, misspellings created problems while searching | Fidel et al. , 1999 (secondaire) (cf. Broch, 2000) |
pb: sont également présentes des difficultés liées à la maîtrise de l’orthographe | Dinet, 1999 |
Difficultés dans l’élaboration des stratégies pb: tendency to conduct simple searches, crafting poor searches; considerable guessing of appropriate terms; typical user only performs 2 or 3 inquiries per search; very small number of citations exa- mined (5-6); abort searches quickly; | Hertzberg et Rudner, 1997 et Nims et Rich, 1998
(cf. Todd, 2001) Hertzberg et Rudner, 1997 c(f. Todd, 2001) |
pb: formulating ineffective search queries; limited use of thesaurus; | Bilal et Watson, 1998; McNicholas et Todd, 1996 (secondaire); Todd, 2000 (cf. Todd, 2001) |
pb: high expectation of the technology’s ability to make up for poor searching techniques | Nims et Rich , 1998 (cf. Todd, 2001) |
pb: Evidence that many searchers are unaware of the role of controlled vocabulary is demonstrated by the fact that many of the children in the study enter their queries using natural language | Bilal, 1998; Nahl et Harada, 1996; Schacter, Chung et Dorr, 1998 (cf. Broch, 2000) |
pb: unfamiliarity with indexing terms made it difficult to formulate the initial search and was even more of a barrier when an initial search failed and subsequent searches were needed | Bilal et Watson, 1998; Borgman et al., 1995; Fidel et al. , 1999; Nahl and Harada, 1996 (cf. Broch, 2000) |
pb: the most significant problems their students encountered in database searching were « generating search terms » and « designing effective search strategies. | Neuman, 1995 (cf. Broch, 2000) |
Difficultés avec les opérateurs booléens pb: failure to utilize Boolean operators | Bilal et Watson, 1998; McNicholas et Todd, 1996 (secondaire); Todd, 2000 (cf. Todd, 2001) |
enq: 44% knew the booleen operators, only 28% used them correctly | Coupe, 1993 (université) |
enq: Not even 1% of the students could identify Boolean searching | Kester, 1994 (secondaire-collège) |
pb: the ability to use Boolean logic on CD-ROM sys- tems shows higher skill rates at tha senior level | Greer, Weston, Alm, 1991 (université) |
pb: Boolean logic is confusing to apply, particularly for children | Borgman, 1996; Borgman et al., 1995; Nahl et Harada, 1996 (cf. Broch, 2000) |
