This paper presents a game-based learning study in Malaysia in which a game has been designed for remedial Mathematics students at primary school level. Mathematics is a core subject taught in all primary schools in Malaysia. However, for students who are recognized as weak in Mathematics, teachers use remedial modules supplied by the Ministry of Education in teaching and learning activities. A research study has been initiated to propose digital game-based learning for the remedial students, aiming to enhance the effectiveness of the modules. A prototype game is designed to be playable on tablet computers. The game contains lessons under the title of Whole Numbers: Addition in Year Two syllabus. This paper reveals the concepts and rationale behind the study and the game design. The research plan is also included to justify the ecological validity of the study.

Purpose: This study compared the short- and long-term clinical outcomes of laser hemorrhoidoplasty (LH) vs. conventional hemorrhoidectomy (CH) in patients with grade II/III hemorrhoids. Methods: PubMed/Medline and the Cochrane Library were searched for randomized and nonrandomized studies comparing LH against CH in grade II/III hemorrhoids. The primary outcomes included postoperative use of analgesia, postoperative morbidity (bleeding, urinary retention, pain, thrombosis), and time of return to work/daily activities. Results: Nine studies totaling 661 patients (LH, 336 and CH, 325) were included. The LH group had shorter operative time (P<0.001) and less intraoperative blood loss (P<0.001). Postoperative pain was lower in the LH group, with lower postoperative day 1 (mean difference [MD], –2.09; 95% confidence interval [CI], –3.44 to –0.75; P=0.002) and postoperative day 7 (MD, –3.94; 95% CI, –6.36 to –1.52; P=0.001) visual analogue scores and use of analgesia (risk ratio [RR], 0.59; 95% CI, 0.42–0.81; P=0.001). The risk of postoperative bleeding was also lower in the LH group (RR, 0.18; 95% CI, 0.12– 0.28; P<0.001), with a quicker return to work or daily activities (P=0.002). The 12-month risks of bleeding (P>0.999) and prolapse (P=0.240), and the likelihood of complete resolution at 12 months, were similar (P=0.240). Conclusion: LH offers more favorable short-term clinical outcomes than CH, with reduced morbidity and pain and earlier return to work or daily activities. Medium-term symptom recurrence at 12 months was similar. Our results should be verified in future well-designed trials with larger samples.
