A quasi-experimental design was used, in which the experimental group received six weeks of Web-based problem- solving instruction in biology and the control group received non-Web-based problem-solving instruction for the same content and for the same period of time. Pre-, post- and retention tests of problem-solving and biology achievement were administered before and at two different time intervals after the instruction. With the pretest scores as a covariate, the results of MANCOVA followed by protected univariate F tests suggest that Web-based problem-solving instruction has the potential to enhance and sustain the learner’s problem-solving skills over an extended period of time. Keywords: Web-based learning; problem solving; middle school biology Introduction Promoting students’ problem-solving ability has been a prevalent objective in the science education community (Blosser, 1988; Bransford, Brown, Cocking, Donovan, states that ‘preparing students to become effective problem solvers alone and in concert with others, is a major purpose of schooling’ (American Association for the Advancement of Science, 1993, p. 282). In addition to problem solving being an educational goal, Watts (1994) suggested that problem solving should be a core skill in the curriculum because incorporating problem solving into the curriculum helps motivate learning, provide enjoyment, stimulate interest and foster creativity. Problems, by their nature and solution strategies, can be divided into two major categories: well-structured problems and ill-structured problems. Jonassen (1997) defined well-structured problems as ‘constrained problems with convergent solutions that engage the application of a limited number of rules and principles within well- defined parameters’ (p. 65). Most problems solved in regular science and mathematics
